事件切割：我们如何知觉并记忆日常事件?

事件切割指的是人们将连续的外界信息析解成若干个有意义且互相关联的事件的过程, 实验室中通常使用事件切割任务对其进行研究。事件切割既包含自下而上的加工过程, 也有自上而下加工的成分。事件切割活动对记忆有着重要的影响, 个体知觉事件、回忆事件的能力被认为与其日常生活紧密相关。解释事件切割加工过程和特征的理论模型主要包括情境模型、事件切割理论和事件视界模型。未来的研究可以深入探讨事件记忆在不同测试类型上的差异, 并关注事件切割过程中的注意分配过程。     

Integrating The Diverse Definitions of Happiness: A Time-Sequential Framework of Subjective Well-Being

The field of subjective well-being (SWB) is primarily concerned with people's evaluation of their lives; however, it includes a wide range of concepts, from momentary moods to global life satisfaction judgments. We propose a framework that integrates these diverse constructs. Our sequential temporal framework of subjective well-being describes experiences of well-being from the events and circumstances that cause evaluative reactions, through the emotional reactions to these events, to recall of these reactions, and finally to global judgments of well-being based on the previous stages. The hypothesized processes that translate the various steps in the sequence into one another are described, and supporting evidence is reviewed. We outline the implications of our framework for understanding subjective well-being, and discuss the research that is needed to further explore the proposed framework.     

Grip strength and physical demand of previous occupation in a well-functioning cohort of Chinese older adults

The grip strength of 214 independently ambulatory Chinese older adults (M age = 75.1 +/- 7.0 yr.) was measured, and preliminary mean values presented. Their previous occupations were recorded, and the physical demands of those occupations in terms of oxygen consumption and work done were classified. Grip strength generally decreased across age groups. The physical demand of individuals' previous occupations had significant associations with grip strength, for example, participants who previously worked as construction site workers had a greater grip strength than those who worked previously as office workers.     

Culture and judgment of causal relevance

The authors hypothesized that because the causal theories of East Asians were more holistic and complex than those of Americans, the amount of information considered before making a final attribution would be larger for East Asians than for Americans. This hypothesis was supported through 4 studies. When participants attempted to explain a deviant behavior (Study 1) or a prosocial behavior (Study 2), Korean participants took into consideration a greater amount of information than did either American or Asian American participants. Study 3 replicated the findings of Studies 1 and 2 within each culture. Finally, Study 4 established a link between the present findings and past research on culture and attribution. Namely, Study 4 found that Koreans made more external attributions than Americans because Koreans considered more information than did Americans.     

Long live Proust: the odour-cued autobiographical memory bump

The autobiographical memory bump is an increase in the frequency of reported autobiographical memories (AMs) from a particular age range, and has been reported by numerous investigators (for reviews, see Conway, M. A. & Rubin, D. C. (1993). The structure of autobiographical memory. In A. F. Collins, S. E. Gathercole, M. A. Conway & P. E. Morris, Theories of memory. Hove: Lawrence Erlbaum; Rubin, D. C., Rahhal, T. A. & Poon, L. W. (1998). Things learned in early adulthood are remembered best. Memory and Cognition, 26, 3-19) to occur in the second and third decades of life. Invariably, word labels have been used as AM cues but, given that a popular interpretation of the anecdotal 'Proust phenomenon' is that odours evoke AMs which are especially aged, we wondered if a different pattern in the AM bump might emerge if AMs were cued by odours rather than labels. Here we report an attempt to substantiate this aspect of the 'Proust phenomenon' by comparing the distributions of memories across the lifespan when cued by odour and label. Data showed that, in line with previous studies, the bump for label cues was found to peak between ages 11 and 25 years and was confirmed to be quadratic in form. In contrast, the odour-cued memory distribution peaked at 6-10 years and decreased linearly thereafter. In the earliest age interval, 6-10 years, the proportion of AMs retrieved in response to odour cues was significantly greater than that for the label cues. These results provide empirical support for the Proust phenomenon, and have more general implications for the structure and age distribution of stored AMs.     

自我与他人视角的动态信息加工：一项行为振荡研究

为了实现流畅的社会互动,个体需要同时加工自我与他人视角下的信息,并能有效地区分二者。然而个体对自我与他人视角下的信息存在共享神经表征,那么大脑是如何在同时完成自我与他人视角信息加工的前提下又不至于混淆二者的呢？本文通过创新性的、具有高时间分辨率的内隐视觉观点采择任务,发现对于自我视角和他人视角下的信息加工存在频率约为1 Hz的行为振荡现象,并且二者存在180°左右的相位差。这一结果说明在有他人在场的社会情景中,自我视角与他人视角下的信息加工是一种具有周期性的交替优势的过程。     

Examining college students' food security coping strategies and experiences during the COVID-19 pandemic

College students' food situations may have been disrupted by the COVID-19 pandemic, which could have affected their health and well-being. However, little is known about how the pandemic impacted students' food experiences and how students coped with food-related disruptions, particularly from the student's own perspective. This study reviews data from 571 undergraduates who attended public colleges during Fall 2021 and Spring 2022 and wrote a narrative about the pandemic's impact on their food experiences. Most students indicated they experienced a wide range of food difficulties and adapted new food practices. Despite these challenges, students emphasized proactive coping strategies and positive pandemic outcomes rather than difficulties and negative outcomes. These findings have implications for students' long-term health and well-being.     

心算对内外倾者的心率、T波幅度和呼吸频率的影响

该文旨在探讨内、外倾者在三种不同难度心算时,心率、Ｔ波幅度、呼吸频率变化的差异。通过艾森克个性问卷筛选出１５名内倾者和１５名外倾者作为被试,让其完成三种不同难度的心算任务。实验结果表明,心算时两组被试心率均显著上升,内倾组上升幅度大于外倾组;Ｔ波幅度显著降低,内倾组降低幅度大于外倾组但差异不显著;呼吸频率显著上升,但两组上升幅度差异不显著。此外,从心率变化上看,两组被试对心算均表现出适应,内倾组的适应速度比外倾组慢。本实验表明,焦虑性精神紧张比智力操作性精神紧张对心率的影响更大。     

Stimulus intensity and foreperiod effects in intersensory facilitation

Intersensory facilitation refers to the more rapid reaction time (RT) to a target in one modality and an accessory stimulus in a different modality compared to a RT to the target alone. Prior studies suggest two processes contribute to the phenomenon, termed the preparatory state and energy integration which refer to the action of accessory stimulation in providing forewarning and intensifying the reaction signal, respectively. Experiment I factorially varied foreperiod duration, light (target) intensity and tone (accessory) intensity in a discriminative RT task. The results were that foreperiod (preparatory state) and intensity (energy integration) effects were additive, implying that they affected separate processing stages. Accessory stimulus intensity affected false alarm rate on catch trials. This suggests that energy integration involves a form of response bias (increased likelihood of responding) and not facilitation (more rapid information processing). Experiment II indicated that comparable energy integration effects obtain with tone as target and light as accessory, as well as vice versa. The findings further indicated that RT to a bisensory pairing is more rapid when attention is directed to the more potent member of the pair.
