社交焦虑注意偏向的动态变化

蒋婧琪; 王浩宇; 钱铭怡
Subjects: Psychology >> Clinical and Counseling Psychology

注意偏向是社交焦虑障碍(Social Anxiety Disorder,SAD)个体症状维持的重要因素,其中注意警觉、注意回避、注意脱离困难三种注意模式得到了研究者最广泛的研究与讨论。随着研究深入,有研究者提出SAD个体的注意模式不是单一、静态模式,更有可能在不同注意模式间切换,表现为动态的过程。目前,依据相关研究结果和理论假设,证据均指向SAD个体的注意偏向具有随着焦虑水平提高和注意控制能力受损而动态变化的倾向,从注意警觉过渡到注意回避与注意脱离困难均如此。此观点还需研究进一步证实,并且基于研究结果提出更具有针对性的干预方式。

ERMSS_WL_The Prosodic Encoding of Focus in Lujiang Dialect.pdf

Lu Wang1; Yao Lu1,
Subjects: Linguistics and Applied Linguistics >> Linguistics and Applied Linguistics

The focus is the component highlighted in the sentence, which can be broadly divided into broad focus and narrow focus. Prosodic encoding of focus can be reflected on pitch, duration and intensity. Different languages and dialects show different characteristics. This paper takes Lujiang dialect in Anhui Province as the research object, and discusses the prosodic encoding of focus in different tones with wide focus and narrow focus. The results show that the prosodic encoding of focus in Lujiang dialect is reflected in pitch, duration and intensity.

ERMSS_ZH_The effect of non-labial facial information on audiovisual speech perception.doc

Zeyu Huang; Yao Lu
Subjects: Linguistics and Applied Linguistics >> Linguistics and Applied Linguistics

We conducted an experiment consisting of five blocks to examine the effect of non-labial facial information on audiovisual speech perception. 20 Chinese native speakers were asked to report the syllables they perceived during five condition: audio-only, video-only, video-only without labial part, audiovisual and audiovisual without labial part. The materials were /pa/, /tsa/, /ta/, /tʂa/ and /ka/, which were selected according to places of articulation from front to back. The results showed that even though the non-labial facial information was not enough to distinguish non-labial consonants, they could have significant effect on auditory speech perception

视网膜上物象对应的外在注视点之间的距离, 即双眼注视点间距(distance of binoculars point of regard, DBPR)在自闭症谱系障碍(autism spectrum disorders, ASD)个体上存 在异常的表现, 而 ASD 个体伴随较高的斜视发病率, 可能会对其双眼注视点间距产生影响。 研究采用正弦曲线平滑追踪任务范式, 探索视觉正常的 ASD 儿童在动态刺激加工过程中 DBPR 的鉴别意义。 结果发现, ASD 儿童 DBPR 过大且具有跨任务类型的稳定性, 且与斜视 无关。 DBPR 在大振幅、 快速度的条件下具有优良的鉴别力, 并与自闭症行为量表总分以及 感知觉维度显著正相关。 结果表明, 双眼注视点间距具有良好的鉴别价值。

执行功能可塑性:任务转换训练的研究

王梓宇; 孔子叶; 朱荣娟; 游旭群
Subjects: Psychology >> Cognitive Psychology

任务转换训练是提高个体执行功能的方法之一。学者们采用不同的任务范式进行任务转换训练。研究结果发现,任务转换训练可以降低个体的转换代价、提高其他认知任务的绩效。训练效果可以维持一定的时间。但是,也有研究未发现明显的迁移效果和维持效果。年龄、其他执行成分的参与度、认知灵活性和策略可能会影响训练效果。任务转换训练可能通过提高个体解决任务设置冲突的能力、提高与任务转换相关的额——顶脑网络的参与程度以及建立自下而上的自动控制来提高个体的转换能力。未来研究应当对现有研究方法和程序进行标准化,从执行功能整体与分离的结构特征角度看待任务转换训练,寻找更为灵活的训练手段,如tDCS技术。
