Abstract： Maternal sensitivity plays a pivotal role in the child's development. A large number of studies have proved the influence of attachment on maternal sensitivity. However, these studies ignored the relationship between attachment styles and cognitive processes of maternal sensitivity, and therefore cannot answer how attachment styles can affect maternal sensitivity The social information processing model of maternal sensitivity integrates crucial cognitive structures and cognitive processes related to maternal sensitivity and divides the cognitive processes of maternal sensitivity into four stages. Based on this model, we reviewed individual differences and mechanisms related to attachment styles at all four stages of maternal sensitivity: emotional perception, maternal attribution, motivational response, and response selection. Future research should further investigate the influence of attachment styles on the cognitive processes of maternal sensitivity from a temporal perspective. Additionally, research should explore the joint influence of multiple cognitive structures on cognitive processes related to maternal sensitivity. Furthermore, attention should be paid to the role of environmental factors in attachment styles and the cognitive processes of maternal sensitivity. Finally, future research should explore the dual influence of attachment style on the cognitive and emotional processes of maternal sensitivity.

Abstract： Attention-deficit/hyperactivity disorder (ADHD) is a persistent neurodevelopmental disorder characterized by inattention and/or hyperactivity-impulsivity, which is closely related to the executive function deficits resulting from the dysplastic of prefrontal cortex. However the underlying psychological mechanisms behind neurological abnormalities leading to core symptoms in children with ADHD remain unclear, particularly how executive function deficits, which are related to abnormal prefrontal development as the underlying cognitive deficit and endophenotype, influence the emergence of core symptoms of ADHD. To address this scientific question about why and how executive function affect the two core symptoms of ADHD, the following aspects are analyzed and discussed. Firstly, based on the neuro - cognitive - behavioral developmental path, it can be inferred that executive function deficits may be the pathogenesis of the core symptoms of ADHD at the cognitive level and act as a cognitive bridge connecting neuro-developmental abnormalities to the core symptoms. Secondly, executive function can be divided into two distinct components: “cold” and “hot”, which may be the two cognitive pathways leading to different core symptoms of ADHD. And these deficits can result in different behavioral manifestations and have diverse effects on developmental outcome. Among that, the “cool” executive function deficits rooted in the dorsal prefrontal cortex might be the dominant factor affecting inattention symptoms, while the “hot” executive function deficits linked to the ventromedial prefrontal cortex might be emerge as the primary contributor to the symptom of hyperactivity and impulsivity. Building upon this understanding, the present study combines empirical and theoretical evidence to investigate the specific mechanisms through which deficits in the subcomponents of “cold” and “hot” executive function influence the two core symptoms of ADHD. And a graph is presented to illustrate the relationships between the abnormal behavioral manifestations and key executive function deficits observed in children with ADHD under these two core symptom categories. Specifically, on the one hand, the deficits in “cool” executive function mainly results in failures in working memory representation, lack of inhibitory control, and difficulties in cognitive flexibility, and further lead to limitations in attention maintenance, selection, and switching. On the other hand, the deficits in “hot” executive function bring problems like delay aversion, reward abnormality and motivation disorders, which make one fail to inhibit behavior and more likely to make impulsive decision, thereby displaying more symptoms of hyperactivity or impulsivity. In addition to elaborating the specific mechanisms of action of executive function deficits affecting core symptoms of ADHD from the perspective of cognitive and neural correlations, further empirical evidence is provided to support and refine the mechanisms from the perspective of causal manipulation of cognitive interventions and neuroregulatory techniques. Finally, future studies are expected to examine and improve the theoretical model of “cold” and “hot” executive function deficits affecting the core symptoms of ADHD, and provide more empirical evidence at the cognitive neural level. Meanwhile, future studies need to examine this influence the mechanism mentioned above in ecological backgrounds, and further develop intervention projects with personalization, precision and long-acting to alleviate the core symptoms of ADHD based on executive function. To sum up, examining the impact and mechanisms of “cold” and “hot” executive function deficit on the two core symptoms of ADHD children from the perspectives of neuroscience, cognition, and behavior is of great scientific value and practical significance. This exploration offers evidence at the cognitive and neuroscience levels, enabling a deep understanding of the pathogenesis of ADHD. Additionally, it provides an evidence-based foundation for individualized interventions and precise treatments for children with ADHD by examining the effectiveness of interventions through causal manipulation of cognitive interventions and neuroregulatory techniques.

Abstract： Owing to its advantages in time resolution, electroencephalography (EEG) provides an important basis for studying the dynamic cognitive process of the human brain. To explore the electrophysiological mechanism of psychological processes, scalp EEG must have good test-retest reliability. Most studies explore the reliability of the resting-state EEG (rsEEG) or event-related potentials (ERP), lacking a comprehensive comparison of multiple states. We comprehensively compared the test-retest reliability of the two rsEEG with eyes-open (EO) and eyes-close (EC) states, and the ERPs of PVT and oddball tasks, from frequency, time, and spatial domains to identify more widely applicable indicators.A total of 42 healthy adults (age range = 18-26 years old; mean = 19.5 ± 1.4 years old; 14 males) underwent all three EEG recording sessions, including the present (Session 1), 90 mins later (Session 2), and one month later (Session 3). During each EEG recording session, all the participants completed the same five states including two resting states (eyes-open, eyes-closed, each with 5 minutes) and two task states (PVT and oddball task). Intra-class correlation coefficients (ICC) were computed to assess the test-retest reproducibility of the five states.This study compares and analyses the test-retest reliability of two resting-state and three task-state EEG from the perspectives of time, frequency, and spatial domains. Results revealed the following: (1) The test-retest reliability of rsEEG was generally better than that of ERP. (2) For rsEEG, the test-retest reliability of the EC resting-state was higher than that of the EO, with the ICC median value of approximately 0.6. Furthermore, the test-retest reliability of the alpha band was the highest in all frequency bands. (3) For the two task-states ERP, the overall ICC of the PVT paradigm was higher than that of the oddball paradigm, and the test-retest reliability was highest at about 200 ms after the stimulus onsets. (4) In the spatial domain, the test-retest reliability is higher in the central region than in the peripheral region, which may be related to the signal-to-noise ratio (SNR).Our research involves multiple resting-state and task-state experiments. Based on the characteristics of frequency, time, and space domains, we comprehensively compared the optimal retest characteristics of multiple EEG and suggest the possible reasons. Some suggestions for the selection of appropriate experimental paradigms and indicators for the follow-up study of EEG test-retest reliability are provided and guide the application of EEG in the basic and clinical fields.

Abstract： As an important aspect of information processing, memory has become a hot spot of research in attachment cognition field during recent years. There are some differences in memory biases of attachment styles by reviewing previous studies, and the results are not always consistent. Based on two theoretical models: the model of attachment related social information processing and the integrative model of the activation and dynamics of the attachment system, it can be concluded into two different processing modes which can partly explain the discrepancy between the previous results, the schematic information processing mode and the strategic information processing mode. Future researches can focus on exploring the inner mechanisms of the two different processing modes, increasing attachment related memory studies of anxious attachment, and examining the application of the two processing modes on improving the insecure attachment state.

Abstract： Maternal behavior is a kind of instinctive behavior with strong motivation and regularity, reflected in a series of care and protection for their pups. Previous studies have shown that maternal behavior does not only affect the emotions, the cognitive and learning abilities of offspring, but also relates to the incidence of cardiovascular diseases. Therefore, the influence of maternal behavior on offspring's psychological functions and behavior has received more and more attention in recent years. A lot of researches have explored the influence of maternal behavior on offspring's psychological functions and behavior and tried to elucidate the mechanisms underlying it. While there is no review to discuss the issues above in details. In the present review, we deeply discussed the effects of maternal behavior on the psychological functions and behavior of offspring. Furthermore, we also tried to explainthe limitations of the previous studies. Lastly, in view of these deficiencies, we put forward some suggestions that might improve the future study work in this field.

Abstract： Researching purpose in life from a psychological perspective is crucial for life education. Progress in this area has shown the following. Despite some differences in definition, researchers agree that purpose in life is essentially about a consistent and central future-oriented aim that gives a sense of direction and meaning to life. The measurement of purpose in life mainly focuses on its content and the extent of being purposeful. A high score on purpose offers a testable system that synthesizes outcomes including better stress coping, healthier behaviors, and better physical and mental state, but it is not clear whether there is a functional distinction between types of purpose in life with different content. The content and extent of purpose in life could be shaped by many factors, including individual and contextual factors. Future studies should further clarify the concept, improve the measurement system, and research on its function and influencers systematically. Additionally, the cultural differences should be considered.

Abstract： Temporal order perception is the perception of the simultaneity, successiveness and order of events in a few milliseconds to hundreds of milliseconds. The exploration of the influencing factors of temporal order perception can be divided into two research orientations: bottom-up and top-down. The bottom-up study explored the effects of stimulus properties, the biological characteristics of the subjects, and measuring methods on temporal order perception. And the top-down study explored the effects of the causal beliefs, emotions and culture on temporal order perception. In the future, it is necessary to combine the behavioral and neuroscience techniques, explore the two processes of temporal order perception to examine whether they are separated or simultaneous, and reveal the brain area that controls timing processing.

Abstract： Memory is a vital component of retrospective duration estimation, which is either assessed by the interval between two successive events, or the duration of an event after it has ended. Retrospective duration estimation can be divided into two types: close-range and long-distance. The timing mechanisms of both are related to memory; however, they have distinct foci. The former focuses on short-term memory or long-term memory; here, direct evidence is derived from the immediate recall of a single or multiple cognitive tasks to estimate time, while indirect evidence refers to the influence of physical, physiological, and psychological factors. The latter emphasizes the role of autobiographical memory, as evidenced by the measurement mode of a questionnaire or an interview and the influencing factors of subject-object characteristics. Future research should focus on further extending the timing mechanism of retrospective duration estimation in an integrated manner, expand the research of behavioral measurement, and explore the basis of neurobiology for retrospective duration estimation.

Abstract： Autobiographical Memory is the memory of personal experiences. Attachment theory provides an important framework for understanding autobiographical memory. Based on the differences in individual attachment styles and the Self-Memory System of Conway and Pearce’s, this article concludes that attachment system plays the role of target director, defensive exclusion and emotion regulation in autobiographical memory retrieval. Studies have found that secure individuals have advantages over insecure ones in the quantity, specificity, accuracy, accessibility, emotional intensity and arousal of memory retrieval. Future research can be carried out on the effects of attachment activation, the differences in specific components of memory retrieval between anxious and avoidant attachment styles, the relationship between attachment and retrieval of involuntary autobiographical memory.

Abstract： It has been identified that physical exercise is able to enhance cognitive functions, attracting attention to the underlying brain mechanisms. The literature shows that the enhancing effects rely basically on two distinct mechanisms, on the microscale and macroscale levels, respectively. At the microscale level, physical exercise favored synaptogenesis and the survival of neurons through better nutrient supply and metabolism. At the macroscale level, physical exercise could enhance cognition through enlarging the volume of white and grey matter, and changing the brain activity and functional connectivity. Notably, multiple factors could influence the enhancing effects of physical exercise on cognition, such as individual differences, time, and the interaction between physical exercise and cognitive stimulations. These factors provide new directions to conduct deep and systematic investigations on the brain mechanisms of enhancing effects on the two levels.

Abstract： Insomnia has high incidence in modern society. The resting-state functional magnetic resonance (rs-fMRI) becomes one of the main imaging methods for the neuroimaging studies of insomnia, with its convenience and non-intrusive during data recording. Recent rs-fMRI studies showed that patients with insomnia had abnormalities in the prefrontal lobe, the temporal lobe, anterior cingulate gyrus and insula. Large-scale brain network is a brain structure that contains multiple brain regions and has relatively unique cognitive function. Based on the perspective of large-scale brain networks, patients with insomnia had abnormal activities and connectivities within the default network, the salience network, the cognitive control network and the negative affect network. More important, growing evidence presented an altered connectivities pattern among these four large-scale brain networks. Based on the symptoms, therapy, and the patterns of the large-scale brain networks, we proposed a "precision treatment" approach for insomnia. Future researches could integrate the big data with multimodal neuroimaging technology to verify the findings of rs-fMRI. Moreover, longitudinal and sequential design of insomnia can further benefit for the understanding of the neural mechanisms of insomnia.

Abstract： As time passes, the dynamic characteristic of retrospective duration estimation is reflected in two aspects: short-term delay and long-term development. The former focuses on delay in seconds and minutes, attributing to context changes or a series of cognitive differences caused by target duration. The latter emphasizes individual development across ages (such as infancy, childhood, and adulthood) and considers differences in the speed of information processing as the main cause. Finally, from a comprehensive perspective, it is believed that the dynamics may be due to distinct mental representation of duration from seconds to minutes, which reflects the range-synthetic characteristic of time cognition. Future research should focus on extending temporal representation in the process of time lapse, further explore the role of timing strategies closely related to the target intervals in the retrospective duration estimation, and expand the dynamic characteristic of individual differences such as age and personality type.

Abstract： The lens model emphasizes that the validity of cues is important in accurate personality judgment. Existing research indicates that text messages, voice communication, face images, video clips reflecting different situations, and face-to-face communication involving many kinds of verbal and nonverbal information play an important role in the process of personality judgment. On the other hand, conventional text and video information against the background of the network can also effectively reflect an individual's personality traits. Besides, the validity of some network languages—the use of facial expressions and status updates and clicking “like,” which are closely related to personality traits—is worth further exploration. Future research should consider the cues into the real-life situation and improve the ecological validity. It is also important to consider comparison between different cues to see which kind of lead is more effective. Finally, future research should be conducted from the perspective of the validity of the individual behaviors in the network situation to try to understand the cues of personality judgment more deeply.

Abstract： The effect of the babyface schema is an innate instinct that promotes the formation of early parent-child relationships; this has been thought to be primarily influenced by the baby's face structure. However, in recent years, the influence of facial expression on this effect has begun to attract attention. With the adult face as the baseline, the size of the babyface schema’s effect will change with different facial expressions, and the effect of a neutral babyface schema becomes the strongest. Because the cause of this phenomenon and its neurological mechanism are still unclear, this project first plans to establish a set of standardized facial pictures of an infant and adult displaying various affective faces. Then, based on this, the researchers will investigate whether facial expression uncertainty can moderate adults’ preferences and attention biases for infants with different facial expressions, and they will furthermore explore the corresponding neurological mechanism to promote research on the parental brain in China.

Abstract： Postpartum depression is a complex phenomenon of severe depressive episodes that occur within a period of time after delivery. Evidences suggest that oxytocin is an important modulator of female reproductive functions including parturition, lactation and maternal behavior, while it also plays an important role in modulating the development of postpartum depression and the maintain of maternal behavior. In postpartum depression patients, the emotional and cognitive impairment might contribute to the impairment of maternal behavior. Oxytocin directly regulates maternal behavior through the mesolimbic dopamine system. Oxytocin acting on medial preoptic area (MPOA) to activate the pathway of ventral tegmental area (VTA)-nucleus accumbens (NAc) and thus modulate the secretion of dopamine in NAc. Finally, we point out that oxytocin mediates maternal behavior in postpartum depression is through its modulation of the serotoninergic system, and its interactions with other hormones. Future studies should focus on functional differences of oxytocin in the central nervous system and the effect of social support on oxytocin uses in postpartum depression.

Abstract： In the context of the effect of acute stress on aggressive behavior, most studies on stress responses involve exposing participants to novel, one-time stressors; however, people are constantly exposed to similar stressors in everyday life multiple times. Compared with the response to one-time exposure to stressors, the ability to adapt to repeated stress has greater evolutionary utility as it preserves resources by relieving the response to non-life-threatening stress; however, little is known about the effect of repeated acute stress on aggressive behavior. In Study 1, we investigated the effect of repeated acute stress on aggressive behavior. Sixty healthy male college students were selected for this study. A modified version of the Trier Social Stress Test for Groups (TSST-G) was introduced as a standardized, economic, and efficient tool to simultaneously induce a psychobiological stress response in a group of subjects. All participants were exposed to the modified version of the TSST-G twice one week apart. The main characteristic of the stress response is the activation of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic adrenomedullary (SAM) system. The HPA axis responses were assessed by measuring salivary cortisol levels. The assessment of the SAM stress system during the experiment was conducted by monitoring its correlates—heart rate (HR), and emotional responses were assessed by measuring state anxiety. Following the modified version of the TSST-G, the Taylor Aggression Paradigm (TAP) was adopted to induce and measure aggression. Subsequently, according to the social information processing model (SIP), we explored the influence mechanism of repeated acute stress on aggressive behavior. After each of the modified version of the TSST-G, participants completed a dot-probe task and a single-target implicit association test (ST-IAT). In Study 2, we further investigated the change in aggressive behavior after the regulation of repeated acute stress through internal channels. First, we investigated the change in aggressive behavior after regulating repeated acute stress by changing the frequency of repeated stress. Participants were exposed to the modified version of the TSST-G twice on consecutive afternoons. We then investigated the change in aggressive behavior after the regulation of repeated acute stress by reducing the intensity of repeated stress. The TSST-G control condition contains all factors except for the psychosocially stressful components—socio-evaluative threat and uncontrollability. Participants were exposed to the TSST-G control condition twice, at an interval of one week. Self-reported state anxiety, salivary cortisol levels, and heart rate were assessed during the protocol. In Study 3, we further investigated the change in aggressive behavior after the regulation of repeated acute stress through external channels. Specifically, using a double-blind, placebo (PL)-controlled between-subjects design, we explored whether intranasal oxytocin (IN-OT) can accelerate the habituation of individuals to repeated stress, thereby reducing aggressive behavior. Participants either took a nasal spray containing oxytocin or a placebo spray. Approximately 40 minutes after OT or PL administration, the participants completed the modified version of the TSST-G. Following the modified version of the TSST-G, the TAP was adopted to induce and measure aggression. Self-reported state anxiety, salivary cortisol levels, and heart rate were assessed during the protocol. The oxytocin receptor (OXTR) genotype is an important factor in IN-OT signal transduction and is also an important reason for individual differences in the behavioral effects of IN-OT. Thus, we further investigated the moderating role of oxytocin receptor genotyping in this process. Specifically, four single nucleotide polymorphisms (SNPs) in OXTR rs53576, rs237887, rs237897, and rs7632287 were tested. These studies have great scientific and practical significance in providing further empirical evidence to support the phenomenon of HPA habituation and the “fight or flight” theory and reveal the effect of repeated stressors in everyday life on aggressive behavior and cognitive processing mechanisms. Additionally, the study of internal and external regulation will help accelerate an individual’s habituation to repeated stress and attenuate the HPA axis responses.

Abstract： The development of natural language processing has offered reliable and valid research methods for exploring the relationship between semantic distance and creative thinking. There are more and more studies in this direction in recent years. However, the research findings are inconsistent in this line of research. It remains unknown whether semantic distance could predict creative thinking and whether this relationship is influenced by other potential factors. Therefore, a more comprehensive study is necessary to investigate the relationship between semantic distance and creativity. To fulfill such a research gap, the present study, based on the Associative Theory of Creativity and the Spreading-Activation Model, has investigated the relationship between semantic distance and creative thinking by using a meta-analysis method. The reasons for the inconsistency of previous studies in this line of research were also analyzed. The current research has involved 14 studies and extracted 53 independent effect sizes from 4729 subjects. Since the heterogeneity test showed that there was significant heterogeneity (I2 = 92.21), the random effect model was used for the meta-analysis. Results of funnel plots, Egger's test of regression, and Fail-Safe Number (Nfs) showed that there were low levels of publication bias in the selected publications. The sensitivity analysis also suggested that the meta-analysis in the present study had acceptable reliability. The main effect analysis suggested that there was a moderate level of correlation between semantic distance and creative thinking (r = 0.379, 95% CI [0.300, 0.452]). Further meta-regression analysis found that the correlation was moderated by the age of participants and dimensions of creative thinking. Specifically, the results suggested that the correlation between semantic distance and creative thinking decreased with the increase in the age of participants. In addition, the flexibility (r = 0.473, 95%CI [0.180, 0.688]) had a higher correlation coefficient with semantic distance than originality (r = 0.328, 95%CI [0.197, 0.447]) and fluency (r = 0.447, 95%CI [0.338, 0.545]). However, elaboration had a negative correlation with semantic distance (r = -0.533, 95%CI [-0.664, -0.372]). The current study showed that semantic distance was associated with creative thinking. It has been suggested that the moderation effects of the age of participants and dimensions of creative thinking might be the potential reasons for the inconsistent results in previous studies. In theory, the present study provides new perspectives and explanations for exploring cognitive and neural mechanisms of creativity. It contributes to the exploration of the relationship between semantic distance and creative thinking. The current study offers better scientific evidence and important implications for interpreting, predicting, and improving creativity. In practice, the current study contributes to quantifying creative thinking by using semantic distance. Future explorations should investigate the relationships between semantic distance and domain-specific creativity (e.g., scientific creativity and artistic creativity), as well as the influence of other higher cognitive functions (e.g., cognitive control) on these relationships.

Abstract： Previous studies based on attachment theory have proved the influence of attachment on emotion regulation. These influences can be manifested in many aspects, such as the choice of emotion regulation strategies, the effect of emotion regulation, and some cognitive processing related to emotion regulation. However, these studies ignore the complexity and diversity of emotion regulation as a process, and therefore cannot answer how attachment can affect emotion regulation. The extended process model divides emotion regulation into three stages, and clearly describes the process of emotion regulation and the relationship between various factors in the process. Combining the extended process model and the attachment theory to look back to previous studies is helpful to find out the relationship among these studies and expand new research directions. From the perspective of the extended process model, it can be found that there are individual differences related to attachment in all the three stages of emotional regulation. Specifically, in the recognition stage, the influence of attachment on emotion regulation is mainly reflected in the cognitive processing related to emotions. Both higher attachment anxiety and attachment avoidance are related to lower emotion recognition ability. At the same time, higher attachment avoidance is related to lower emotion recognition ability, and higher attachment anxiety is related to lower emotion regulation self-efficacy. In the selection stage, individuals with different attachment styles have different preferences for the choice of emotion regulation strategies. Most studies have found that individuals with secure attachment prefer to use highly adaptable and efficient strategies (such as cognitive reappraisal), and individuals with insecure attachment styles prefer to use strategies which are less adaptable and efficient(such as hypo-regulation or hyper-regulation). In the implementation stage, most studies have found that both attachment anxiety and attachment avoidance are significantly positively correlated with emotion regulation difficulties or disorders, but in some studies, high attachment avoidance individuals may not have problem with emotion regulation. In general, many factors are influenced by attachment in the process of emotion regulation, and the extended process model provides a theoretical framework for describing the sequence and causal relationship between these factors. However, there are still many key issues that have not yet been resolved. Future research can be expanded from the following aspects: The influence of attachment on emotional regulation should be explored while paying attention to the impact of environmental factors; New experimental paradigms need to be designed to confirm the continuity of the three stages and explore the reasons why attachment could affect emotional regulation. It is necessary to explore the influence of attachment on the emotion regulation flexibility. In addition, future intervention studies should design more targeted interventions to improve the emotion regulation of insecurely attached individuals.

Abstract： Procrastination, as Steel (2007) reviewed, is the phenomenon that individuals voluntarily delay to start or complete an intended course of action despite expecting to be worse off for the delay. The previous studies have indicated that chronic procrastination exists in different cultural backgrounds, with about 15% ~ 20% of adults troubled. Academically, more than 40% of students admit to academic procrastination, and some may even suffer from chronic tendencies. With the rapid development of modern society, the problem of procrastination is more serious and prominent. Obviously, putting off the task irrationally not only does harm to individuals’ study, work, emotion, but also endangers mental health. However, little is known about procrastination concerning the core mechanism of origin, the critical period of its formation, and its corresponding underlying neural substrates. To fill this gap, the current study investigates the core mechanism of procrastinated decision - making which rely on the Temporal Decision Model (TDM) we outlined, and explores the developmental cognitive neural mechanism of procrastination form a behavior - environment - brain perspective, and also sheds light on how to prevent or intervene the procrastination in these critical periods. First of all, the behavioral development measurement of the study aims to use a cross-sectional design to explore the occurrence and developmental characteristics of procrastination, the critical period (sensitive period) and the relevant influence factors (including various environmental and educational variables) of procrastination formation in children with three age groups (6 ~ 8 years, 10 ~ 12 years, and 12 ~ 15 years). And we also investigates the effects or underlying mechanisms of the cognitive abilities such as self-control, long-term value evaluation, time discounting, and emotion regulation on procrastination at each age stage. Meanwhile, the time decision model of procrastination is tested and refined in the study form a developmental perspective. Secondly, on the basis of neural level, procrastination is related to functional deficits in the frontal lobe, limbic system (e.g., amygdala, hippocampus) and other brain regions. Thus, the brain development measurement of the study aims to examine the development of brain structure and brain function in children aged 6 ~ 15 years using Magnetic Resonance Imaging (MRI) multimodal imaging techniques (including task, resting, voxel-based morphometry (VBM), diffusion tensor imaging (DTI)), and functional Near-Infrared Spectroscopy (fNIRS) techniques. Based on the correlation analysis among brain structural data, functional data and behavior data, the study systematically investigates the developmental cognitive mechanisms of procrastination that are influenced by relevant influence factors, such as long-term value evaluation, delay discounting, self-control, emotion regulation and episodic future thinking. In addition, the study intends to build a behavioral - environmental - brain multilevel model for predicting the formation of procrastination in children. By integrating multimodal data on behavior, environment, and brain variables, the influence of environmental variables on procrastination through the malleability of brain structure and function is examined using the mediation analysis and structural equation model. What’s more, considering behavioral intervention for procrastination and malleability of the brain development, the study also sheds light on develop a clinical proposal for the prevention and intervention of procrastination at each critical periods according to the developmental characteristics of each age (including childhood, adolescence, and adult), mainly using intervention training methods, such as episodic future thinking, time management, and emotion regulation, and so on. To sum up, on the one hand, the current study can reap enormous scientific contributions to clarify the neurocognitive mechanism and the rules of development of procrastination; on the other hand, the study further obtain the practical significance for the prevention and intervention against procrastination behavior with exploring the effectiveness of intervention from the perspective of brain malleability.

Abstract： The interference of space on time and vice versa are common in daily life. The spatiotemporal interference effect is a phenomenon in which temporal perception is disturbed by spatial information or spatial perception is disturbed by temporal information. Some studies suggest that spatiotemporal interference is asymmetric, and the spatial interference on time is always greater. Other studies indicate that the strength of mutual interference between time and space is influenced by experimental factors. In general, spatial interference on time is greater, but time can also produce the same degree or even greater interference on space. Results of previous studies on the direction and strength of spatiotemporal interference effects have been controversial, and there are phenomena in which space interferes with time to a greater degree, time interferes with space to a greater degree, and time and space interfere with each other to an equal degree. A rational theory is required to explain the phenomena and mechanisms of the spatiotemporal interference effect. Some reviews have introduced related research, but they all explain the spatiotemporal interference effect from the perspective of metaphor theory and a theory of magnitude (ATOM). In recent years, researchers have applied Bayesian models to the field of spatiotemporal interference effects and have achieved rapid developments in this area, but no systematic review of these studies has been conducted. Therefore, it is necessary to summarize and discuss the research that has used Bayesian models to explain spatiotemporal interference effects.First, this paper introduces the recent studies related to the spatiotemporal interference effect and reviews the main viewpoints of metaphor theory and ATOM to explain the spatiotemporal interference effect. Metaphor theory suggests that people's tendency to use spatial metaphors to think about time extends into the perceptual domain, producing asymmetrical spatial interference on time, and ATOM proposes that temporal and spatial information are processed in a common magnitude system in the parietal cortex, which allows time and space to influence each other comparably but not necessarily symmetrically. Then we highlight four types of Bayesian models in the field of spatiotemporal interference effect research: the constant velocity Bayesian model, the slowness Bayesian model, the dimensional covariance Bayesian model, and the ATOM Based Bayesian model. Next, based on Bayesian models, we propose a new interpretation of the generation mechanism of spatiotemporal interference. The Bayesian model that explains the effect of temporal perception interfered by spatial information can serve as an example. The observer's perceptual time (posterior) is an integration of the time in experience (prior, a belief that longer distances take longer to arrive) and the time of sensory input (likelihood). The more unreliable the sensory input (e.g., low salience of temporal stimuli), the more the observer will rely on the prior and be interfered by the spatial information from the prior, resulting in a spatiotemporal interference effect. The Bayesian models assume that the spatiotemporal interference effect is not always symmetrical or asymmetrical, and the direction and strength of the spatiotemporal interference effect is modulated by the relative noise of spatial and temporal information in working memory (i.e., the relative variance of spatial and temporal likelihood distributions). If they are of equal size, there will be symmetrical interference between space and time; if they are of different sizes, there will be asymmetrical interference from the dimension with less memory noise (i.e., smaller variance of the likelihood distribution) to the other dimension. Thus, the symmetry of the spatiotemporal interference effect can be affected by experimental factors such as stimulus saliency and perceptual acuity. Finally, we discuss the relationship between metaphor theory, ATOM, and Bayesian models. All three accounts propose that people expect space and time to co-vary in the same direction, which suggests that we can assimilate reasonable views of spatiotemporal relations in metaphor theory and ATOM to the prior hypotheses of Bayesian models and then construct an optimal model in the future by optimizing the prior and revealing the neural basis of the inference and decision-making processes. Specifically, three issues should be addressed in further studies: (a) expanding the scope of the Bayesian model to explain the spatiotemporal interference effect, (b) exploring the neural mechanism of spatiotemporal interference based on Bayesian inference, and (c) seeking regulation methods for spatiotemporal interference, which laid a foundation for unraveling the cognitive and neural mechanisms of spatiotemporal interference in the future.
