Is the Lateralized Categorical Perception of Color a Situational Effect of Language on Color Perception?

This study investigated whether and how a person's varied series of lexical categories corresponding to different discriminatory characteristics of the same colors affect his or her perception of colors. In three experiments, Chinese participants were primed to categorize four graduated colors—specifically dark green, light green, light blue, and dark blue—into green and blue; light color and dark color; and dark green, light green, light blue, and dark blue. The participants were then required to complete a visual search task. Reaction times in the visual search task indicated that different lateralized categorical perceptions (CPs) of color corresponded to the various priming situations. These results suggest that all of the lexical categories corresponding to different discriminatory characteristics of the same colors can influence people's perceptions of colors and that color perceptions can be influenced differently by distinct types of lexical categories depending on the context.

时间顺序与时间距离对语言理解的影响:进一步的证据

探讨时间顺序和时间距离对语言理解的影响,包括2个实验.实验采用关系再认范式(relation-recognition paradigm)和句子-探测再认范式(sentence-probe-recognition paradigm).实验一探讨探讨在简单句条件下,时间顺序对不同频率事件理解的作用;实验二探讨在复句条件下时间顺序与时间距离对语言理解的影响.2个实验结果一致表明,在语言理解过程中,存在对将来取向(顺时序)的事件进行优先加工处理.时间距离对语言理解的影响取决于不同时距的事件能否整合成情景模型.     

文本表述结构对空间维度非线索更新的影响

采用实时窗口阅读技术,探讨阅读中文本表述结构在情境模型空间维度非线索更新中的作用。实验一结果表明,阅读中,如果文本叙述中采用以人为参照的描述方式,那么可以促进相应空间设置内物体的实时更新。实验二考察了空间设置不同程度的描述对空间信息加工中的影响,结果发现,相对于对空间设置的简单描述,在文本中对空间设置进行精细阐述更有利于情境模型空间维度非线索更新的达成。     

Situation Awareness and Workload in Aviation

A pilot faces special challenges imposed by the need to control a multivariate lagged system in a heterogeneous multitask environment. The time lags between critical variables require prediction in an uncertain world. The interrelated concepts of situation awareness and workload are central to aviation psychology. Three components of situation awareness are spatial awareness, system awareness, and task awareness. Each of these components has real–world implications, spatial awareness for instrument displays, system awareness for keeping the operator informed about actions that have been taken by automated systems, and task awareness for attention and task management. Task management is directly related to mental workload, as the competing demands of tasks for attention exceed the operator's limited resources.     

Caught in the act: How extraverted and introverted friends communally cope with being recorded

This study explored how close friends who were similar or opposite on extraversion communally coped with being put on the spot to produce a recorded conversation. Participants were 50 pairs of same-sex college-age friends (54% female) who explicitly discussed the fact that their conversation was being recorded. The initial ‘on-stage’ episode emerged consistently earliest for extraverted dyads, and the majority of their episodes quickly diverted the on-stage moment. Dyads that included at least one introvert engaged in more extensive assortments of on-stage maneuvers, including research talk, soothing, and joking. In introvert–extravert dyads the extravert usually initiated and ended these episodes. Implications are discussed for understanding how personality is reciprocally implicated in managing shared everyday problems.
