Abstract： With the application of confirmatory factor analysis, research on reliability has entered a new stage. In the first two decades of the 21st century, the studies on test reliability (including point estimation and interval estimation) in China’s mainland show three main lines of development. The first line is the development from research centered on the coefficient αto the reliability research based on confirmatory factor models, including the homogeneity coefficient, composite reliability, maximum reliability, single-indicator reliability and reliability of the whole item set scores. Studies have shown that the coefficient αis still useful. In most cases, the α coefficient is the lower bound of the reliability of the composite score (total or average score). As long as the coefficient αis high enough, the test reliability will be even higher. But the coefficient αcannot be used to measure the homogeneity and the internal consistency of a test. The homogeneity coefficient based on the bi-factor model can be adopted to measure the homogeneity of a multidimensional scale, and the composite reliability can be adopted to measure the internal consistency (if consistency is understood as the consistency within each dimension). Furthermore, the Delta method can be employed to estimate the confidence intervals of various reliability. The second line is the expansion of data types collected by scales (or questionnaires), from single-level data to multi-level and longitudinal data. Whether unidimensional or multidimensional, it is recommended to use a multi-level confirmatory factor model to calculate the reliability of multi-level data. As for the longitudinal data, it is recommended to use the test reliability developed on the basis of the linear mixed model, and the longitudinal data can also be used as a special case of the two-level data for reliability analysis. The third line is the extended use of reliability, involving rater reliability, encoder reliability, attribute-level classification consistency in cognitive diagnostic assessment, and reliability of difference scores. In addition, research of reliability generalization and reliability meta-analysis appeared. For a common test with item-errors that can be reasonably assumed uncorrelated, the following procedure of reliability analysis is recommended. When the coefficient αis high enough, report the coefficient α; otherwise calculate the composite reliability on the basis of the factor model. If the composite reliability is high enough, report the composite reliability; otherwise the test reliability is considered unacceptable. If the composite reliability of every variable in a statistical model is very high (over 0.95), modeling with composite scores does not differ much from modeling with latent variables. Otherwise, it is better to use latent variable modeling.

Abstract： None quantitative comparisons of reliability for assessment tools for OCD so far. The selection of appropriate scales may be difficult for clinicians. Therefore, this study systematically reviewed the OCD scales used in the child and adolescent populations over a 30-year period to evaluate the reliability coefficients. The results of the meta-analysis indicated that the overall reliability of current OCD assessment instruments in children and adolescents is good. Of all the OCD scales for children and adolescents, the Children’s Florida Obsessive Compulsive Inventory had the lowest internal consistency coefficient and the Padua Inventory had the highest internal consistency coefficient. It is recommended that our primary and secondary school mental health practitioners use the Obsessive Belief Questionnaire-Child Version to assess obsessive-compulsive thinking and the Padua Inventory or the Obsessive-Compulsive Symptoms Questionnaire of Adolescent to assess obsessive-compulsive behavior.

Abstract： Single-item measures have long been debated by researchers. Proponents advocate the efficiency of single-item measures, while opponents question reliability and validity of them. Through comprehensive qualitative and quantitative reviews, advantages and disadvantages of single-item measures are summarized, and doubts and debates in the literature are analyzed and responded specially. Through systematic review, results show that single-item measures have acceptable level of reliability and validity. More notably, the criterion-related validity of multi-item measures is not superior than single-item measures. With the review and current findings, issues that should be noted during the development and usage of single-item measures were addressed. Although multi-item measures are more acceptable, single-item measures may also have its legitimacy in academic research. That is, researchers should value the potential advantages and application scope of single-item measures, so that single-item measures can play its appropriate role in managerial psychology and social science research.

Abstract： Social account credibility evaluation is an important link to ensure the benign development of network social ecology. Aiming at the problems of multi-dimensional credibility evaluation indexes and various data information uncertainty, this paper proposed a credibility evaluation method based on the improved hierarchical belief rule base. Firstly, this paper constructed a hierarchical structure by analyzing the relationship between the indicators of credibility evaluation from three perspectives: account attribute, communication attribute, and content attribute. Secondly, this paper introduced an adaptive coefficient into the information transformation function to better deal with the characteristic differences between indicators. Finally, to make up for the model error caused by the limitation of expert knowledge, this paper used the covariance matrix adaption evolution strategy with projection to optimize the adaptive coefficients and model parameters. Taking Sina Weibo account as the experimental object, the results show that this method can obtain higher accuracy when the data samples are limited.

Abstract： As the features of service composition such as large scale, high complexity, various failures and resource dynamics, a safe and credible service composition scheme is one of the biggest challenges for flexible deployment and on-demand providing. Based on the critical analysis of block chain infrastructure, consensus mechanism and programmable features, contrasting to the characteristics and process of web service composition, this paper developed an novel service composition system architecture with much more credibility and reliability using service overlay networks (SON) theory; In addition, considering the security strategies derived from block chain consensus mechanism, and making full use of smart contract’s functions and effects, this paper proposed an effective algorithm based on the predictive route life time(RLT) and service intensity(SI) across overlay networks for the generation of service paths. Besides, it designed a better service-path selection algorithm which was decided by the trusted quality of service (ToS) model with the single-node’s trust index and interactive tightness index. The simulation results show that the service composition strategy based on block chain mechanism has greatly increased the success rate and credibility of service components after composition.

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： The impression of trustworthiness based on facial appearance plays an important role in interpersonal trust and cooperative behavior. Previous research results have indicated that a variety of additional information (e.g., facial features, context) could affect facial judgments by both bottom-up and top-down processes. However, the mechanism of the two adjustment factors is still unclear. Focusing on this issue, our previous research has found that the top-down process is dominant when both approaches work together. Based on previous findings, the current research proposes the “experience transfer hypothesis”, that is, whether additional information could adjust the trustworthy evaluation of the current face is depended on the evaluator’s previous experience and its generalization results. Experience generalization determines the success of experience transfer. When new cues are lack of similarity to the cues from previous experiences or when previous cues are not strongly associated with the propensity to trust, the experience of trust will not be transferred to the new condition and thus the adjustment factors will fail. When people face two conflicting adjustment cues, the cue which is more similar to the previous cues that are closely related to trust tendencies will dominate the adjustment effect. Under the experience transfer hypothesis framework, this research will design and conduct behavioral experiments to verify the critical role of previous experience in adjusting facial trustworthiness. At the same time, we will use neuroimaging techniques to explore the cognitive neural mechanism of facial trustworthiness adjustment. For this purpose, three studies have been designed in the present research. Study 1 is designed to investigate the cognitive mechanism of the bottom-up and top-down adjustment factors and verify the moderating effect of experience transfer on the evaluation of facial trustworthiness. Regarding the adjustment effect, Study 2 will explore the boundary conditions of experience transfer from three different aspects: the similarity of visual cues, the correlation between visual cues and the tendency to trust, and the contrast effect of different visual cues. Referring to the adjustment process, by using neuroimaging techniques, Study 3 will explore the influence of adjustment direction, and clarify the neural mechanism of facial trustworthiness evaluation. This project proposes the “experience transfer hypothesis” theoretically and introduces the variable “experience” into the process of facial evaluation adjustment, providing new ideas and empirical evidence to deepen our understanding of how interpersonal trust builds. Moreover, this research will systematically answer the question that how people use previous experiences to adjust the evaluation of facial trustworthiness on a given first impression. We will explore the boundary conditions of experience transfer, the influence of adjustment directions on the evaluation of facial trustworthiness, and find out the reason for the failure of facial evaluation adjustments. The solution to the above problems will help to deepen the exploration of the mechanism of trust behavior and improve the theory of facial evaluation. It has important theoretical significance for our in-depth understanding and discussion of the regulation mechanism of interpersonal trust. Meanwhile, it can help people improve interpersonal trust while maintaining their original appearance through the establishment of external experience. This research will provide the empirical basis for further prediction and adjustment of interpersonal trust behavior, offer suggestions for creating a harmonious and credible interpersonal relationship and social atmosphere, and guide people to adjust their own trust levels more effectively.

Abstract： The single image haze removal algorithm based on dark channel priori is currently the most efficient image defogging technology. However, when the image does not fully satisfy the dark channel priori, many artifacts and color distortion will appear in the processed image, so that the method should be modified according to the image situation. This paper proposed the hypothesis that the brighter the scene is, the less credible the dark channel priori will be; the lower the scene saturation is, the less credible the dark channel priori will be. Based on this assumption, an image’s dark channel confidence was designed to limit the dark channel value when the scene does not fully satisfy the dark channel prior. Furthermore, the image was post-enhanced to improve the visual effect. Three typical fog weather images were selected to verify the effectiveness of the proposed method. The experimental results show that the proposed algorithm performs better in preserving color and removing artifacts comparing to some current related defogging algorithms. A new dark channel confidence calculation method is designed to overcome the problem that the estimation of dark channel value will be too large when the image scene does not fully satisfy the dark channel priori. The proposed method improves the adaptability of the dark channel priori defogging model to different foggy scenes.

Abstract： The positivity effect in facial trustworthiness evaluation refers to the phenomenon that older adults (OA) tend to evaluate unfamiliar faces as more trustworthy than younger adults (YA). Numerous previous studies have reported the presence of the positivity effect in judgments of trustworthy, neutral, and untrustworthy unfamiliar faces. Socioemotional selectivity theory (SST) and the dynamic integration theory (DIT) explain the underlying mechanisms of the positivity effect from the perspective of cognitive control and cognitive decline respectively, but a unified model has yet been established. According to the SST, OA with adequate cognitive resources can actively improve their evaluation of facial trustworthiness by selectively paying more attention to trustworthy faces or/and less attention to untrustworthy faces. In contrast, according to the DIT, cognitive decline in OA can lead to a passive increase in attention towards trustworthy faces or/and a decrease in attention towards untrustworthy faces, which can also improve the evaluation. There are discrepancies in the results of previous empirical studies as well. Some studies have supported the motivation explanation of the SST by demonstrating that OA may require sufficient cognitive resources to better process trustworthy faces than YA and thereby improve the evaluation of these faces. However, other studies have supported the cognitive explanation of DIT by showing that OA may “passively” improve their trust evaluations by reducing their processing of untrustworthy faces due to cognitive decline. Neuroimaging studies have found that the functions of the amygdala and anterior insula, which are sensitive to untrustworthy faces, decline with age. This could lead to a decrease in the ability of OA to recognize untrustworthy faces, resulting in reduced processing of such faces and a perception of higher trustworthiness evaluation. On the other hand, the function of the caudate nucleus, which is sensitive to trustworthy faces, enhances with age. This may enhance the rewarding significance of trustworthy faces for OA, resulting in increased processing of such faces and a perception of higher trustworthiness. Based on the theoretical mechanisms and empirical researches mentioned above, a dual-process model of the positivity effect in facial trustworthiness evaluation is proposed. Specifically, for trustworthy faces, OA may tend to “actively” increase their attention to it and show higher trust evaluations through cognitive control. For untrustworthy faces, OA may “passively” decrease their attention to it due to cognitive decline and show higher trust evaluations. Future research should take into account the physiological, psychological, and social changes that come with aging to construct a more comprehensive theoretical framework for explaining the OA positivity effect in facial trustworthiness evaluation. Secondly, by quantifying the age-related differences in facial trustworthiness at different stages using eye-tracking and event-related potentials (ERPs), we might be able to better understand the cognitive mechanisms underlying the positivity effect. In addition, using multiple analytical methods and combining them with behavioral data can further clarify the neural mechanisms. Finally, mindfulness practices as well as transcranial magnetic stimulation can be also introduced to help reduce older adults' vulnerability to fraud in the initial interpersonal interactions.

Abstract： The positivity effect in facial trustworthiness evaluation is that older adults are more positive in trustworthiness evaluation of unfamiliar faces than younger adults. Socioemotional selectivity theory and dynamic integration theory explain its mechanisms from the perspective of cognitive control and cognitive decline respectively, but a unified model has yet been established. Existing studies have found that under the condition of sufficient and insufficient cognitive resources, older adults would improve the trustworthiness evaluation of trustworthy and untrustworthy faces respectively. Neuroimaging studies have found that the decline of the amygdala and anterior insula may reduce the sensitivity of older adults to untrustworthy faces, while the hyperactivation of the caudate may enhance their sensitivity to trustworthy faces. In light of previous studies, a dual-process model of the positivity effect in facial trustworthiness evaluation was proposed. Future studies should attempt to construct a more comprehensive theoretical explanation framework, investigate the age difference of facial trustworthiness processing and clarify the neural mechanism by using a variety of analysis methods. Furthermore, mindfulness practices as well as transcranial magnetic stimulation can be introduced to help reduce older adults' vulnerability to fraud in the initial interpersonal interactions.
