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.     

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.     

组织行为学中的时间相关研究与未来方向

绝大部分组织行为学研究都是从静态视角聚焦变量在一段时间内的整体平均水平, 而忽视了时间的角色, 如变量在一段时间内的动态变化特征。通过引入时间的角色, 从动态视角关注变量的动态变化特征并探讨其影响因素和结果, 可能为现有研究提供新的、突破性视角, 进而帮助拓展传统管理理论。鉴于其对理论发展的重要性, 近年来, 部分新近研究开始逐步关注时间的角色, 从动态视角探索变量的动态变化特征。然而, 整体来看, 这类研究仍相对较少, 且分散在不同的研究领域, 还未能形成结构化体系。基于此, 在将相关研究按照两个维度——变量的动态变化特征的类别(趋势 vs. 波动)与变量的动态变化特征的角色(自变量 vs. 因变量)分为四大类别后, 系统地回顾和梳理相关研究, 并厘清研究背后的理论机制。最后, 基于以上梳理分析, 未来研究可从关注变量的波动; 考察趋势、波动和整体平均水平等的交互作用等角度出发, 更加全面、系统地扩展组织行为学理论。     

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.     

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。     

干扰材料的熟悉性和认知方式对语篇阅读的影响

采用熟悉词和不熟悉词为干扰材料,考察了干扰材料的熟悉性对语篇阅读的影响.实验第一阶段要求不同认知方式被试朗读插入熟悉度不同干扰材料的短文,考查被试的阅读效率;第二阶段采用学习—自由回忆任务考查不同提示条件下在短文中使用过的干扰词和新词的学习效果.结果发现:(1)对场独立者而言,熟悉词的干扰作用明显大于不熟悉词,而对场依存者而言,熟悉词和不熟悉词的干扰作用无差异;(2)在提示条件下,被试对干扰词的回忆量大于对新词的回忆量.研究结果表明,在语篇阅读过程中,与场依存者相比,熟悉的干扰材料对场独立者的影响更大;熟悉词比不熟悉词产生更大干扰的原因可能是由于其激活了读者更多的经验,而非具有加工的优势.     

信息的充分性和情绪性对推理的影响：时间压力的调节作用

主要探讨推理中信息相关因素对分析系统与启发式系统的影响。通过两个实验考察信息的充分性和情绪性对突发事件情境下推理的影响。实验1任务无时间压力,结果发现：信息充分性对推理的影响显著,表现为信息越充分,被试推理的逻辑指数越高,更多使用了分析系统;且信息充分时,接受积极信息的被试的信念指数显著增高。实验2任务有时间压力,结果发现：信息的情绪性对推理的影响显著,表现为接受积极信息的被试推理的逻辑指数显著大于接受消极信息组,更多使用了分析系统。两个实验结果表明,信息的充分性主要通过分析系统对推理产生影响,而信息的情绪性可通过双系统影响推理过程,即积极信息在推理时间充裕时促进启发式系统,但在有时间压力下促进分析系统。     

Biculturalism amongst ethnic minorities: Its impact for individuals and intergroup relations

This review article offers an integration of acculturation, biculturalism, and intergroup relations research. Additionally, it argues that bicultural identities can be more accurately conceptualised as a third, hyphenated cultural identity (e.g., Chinese‐Australian), in addition to one's ethnic and the dominant national identity. In doing so, this article proposes that hyphenated cultural identities may be personally meaningful for many ethnic minorities and discusses the function of hyphenated cultural identification for individuals and society. Given the relevance of bicultural identification, it is argued that recognising and understanding a hyphenated cultural identity is fundamental to ethnic minorities' wellbeing, as well as improving the quality of intergroup relations in multicultural societies, such as Australia.     

Assessing Proprioception in Children: A Review

Proprioception is the subconscious and conscious awareness of the spatial and mechanical status of the musculoskeletal framework. When working with children with motor delays and sensory integrative dysfunction, occupational therapists routinely assess the client's proprioceptive system. However, currently available assessments for occupational therapists are primarily observer-based and concerns have been raised about the reliability of observer-based assessments of sensation. The author's purpose was to review measures of proprioception currently available to occupational therapists and explore direct measures of proprioception from neuroscience and rehabilitation that can be adapted for pediatric clinical use. Observer-based and direct measurements of proprioception assessments complement each other in meeting clinical needs. A better understanding of both types of evaluation will improve proprioceptive evaluation.
