The pre-reflective experience of “I” as a continuously existing being: The role of temporal functional binding

The present moment is of infinitesimally brief duration. In the brain, however, there are perceptual processes that bind together events occurring at different times, on a time scale of milliseconds, into a coherent and integrated temporal representation. These processes include temporal integration, as in perception of biological motion, synchronisation, and change detection. These processes are also responsible for temporal integration and coherence in inner mental life, such as in mental imagery. I argue that this gives rise to the pre-reflective experience of the self as a continuously existing being. Temporal integration is also a feature of the experience of action–outcome relations, and I argue that this produces a pre-reflective experience of the self, not just as continuously existing, but also as the doer of both physical and mental actions. This is the foundation on which the idea of the self as continuously existing on longer time scales – the narrative self – is built.     

Better moods for better eating?: How mood influences food choice

How do moods influence one's preference for foods? By introducing the role of enjoyment- versus health-oriented benefits of foods in the mood and food consumption relationship, this research informs both temporal construal theory and mood management framework by positing that mood influences the choice between healthy versus indulgent foods through its impact on temporal construal, which alters the weights people put on long-term health benefits versus short-term mood management benefits when making choices. The results from four experiments show that a positive mood cues distal, abstract construal and increases the salience of long-term goals such as health, leading to greater preference for healthy foods over indulgent foods. The results also show that a negative mood cues proximal construal and increases the salience of immediate, concrete goals such as mood management, leading to greater preference for indulgent foods over healthy foods.     

时间分层加工研究述评

为了探讨数秒内不同层级时间加工的特性,研究者分别从“时间信息加工”和“信息加工的计时特性”角度开展了一系列研究。Münsterberg (1889)、Michon(1985) 、Lewis 和 Miall(2003) 及Vierodt(1868)从前一角度,分别指出1/3秒、1/2秒、1秒及3秒可能是数秒以内时距加工机制的分界点,分界点以下与以上的加工机制存在差异。P?ppel(1997, 2009)则从后一角度指出限制信息加工过程的两类时间窗,一类时间窗是以20-60毫秒振荡周期运行的高频系统,属于初级整合单元;另一类时间窗主要是处理2-3秒以内事件系列的低频系统,属于高级整合单元。前一类时间窗可以为信息加工整合基本的心理事件,后一类时间窗则是把2-3秒内的心理事件整合为基本知觉单元。基于以往研究的剖析,我们认为1/3秒、1/2秒及1秒等分界点的真伪性尚需进一步验证,并进一步假设40毫秒以内时间不能觉察为时距;40毫秒至3秒之间,随着长度增加,自动化加工减弱,控制性加工增强;3秒以上主要为控制性加工,涉及记忆过程。     

Skilled players’ and novices’ difficulty anticipating left- vs. right-handed opponents’ action intentions varies across different points in time

A left-handers’ performance advantage in interactive sports is assumed to result from their relative rarity compared to right-handers. Part of this advantage may be explained by athletes facing difficulties anticipating left-handers’ action intentions, particularly when anticipation is based on kinematic cues available at an early stage of an opponent’s movement. Here we tested whether the type of volleyball attack is predicted better against right- vs. left-handed opponents’ movements and whether such handedness effects are evident at earlier time points in skilled players than novices. In a video-based experiment volleyball players and novices predicted the type of shot (i.e., smash vs. lob) of left- and right-handed volleyball attacks occluded at six different time points. Overall, right-handed attacks were better anticipated than left-handed attacks, volleyball players outperformed novices, and performance improved in later occlusion conditions. Moreover, in skilled players the handedness effect was most pronounced when attacks were occluded 480 ms prior to hand-ball-contact, whereas in novices it was most evident 240 ms prior to hand-ball-contact. Our findings provide further evidence of the effect of an opponent’s handedness on action outcome anticipation and suggest that its occurrence in the course of an opponent’s unfolding action likely depends on an observers’ domain-specific skill.
