思维聚焦对发展型文化消费产品购买意愿的影响

本研究探析了消费者的思维聚焦（过程聚焦/结果聚焦）对发展型文化消费产品购买意愿的影响,发现结果聚焦的消费者比过程聚焦的消费者对发展型文化消费产品的购买意愿更强烈。同时,时间距离对这一效应存在调节作用,即时间距离远时,这一效应显著;时间距离近时,思维聚焦对发展型文化消费产品的购买意愿没有显著影响。此外,本研究进一步考察了时间距离较远时,消费者的未来时间洞察力部分中介了思维聚焦对发展型文化消费产品的购买意愿。     

触觉时序知觉手臂交叉效应的性别差异

本研究探讨触觉时序知觉的手臂交叉效应是否存在性别差异。通过两个实验在较短和较长的SOA条件下考察男性和女性被试在基于体觉和基于外部空间的触觉时序判断任务中的表现。结果表明,男性与女性被试在基于体觉和基于外部空间的触觉时序判断任务中均存在手臂交叉效应,SOA较短时男性被试的手臂交叉效应显著小于女性被试,但在SOA较长的条件下手臂交叉效应没有明显的性别差异。触觉时序知觉手臂交叉效应的性别差异可能与空间知觉能力和生理解剖学因素有关。     

心理距离对基线比例忽略的影响

基线比例忽略是指在不确定情境中, 个体进行判断和决策时不能充分利用或者忽略基线比例的现象。本研究通过系列情境实验探索了三种不同维度的心理距离, 即时间距离、空间距离和社会距离对基线比例忽略的影响。结果发现, 三种心理距离均能够对基线比例忽略产生影响：当时间距离、空间距离和社会距离较近时, 个体更容易表现出基线比例忽略现象; 而当时间距离、空间距离和社会距离较远时, 个体的基线比例忽略倾向减弱。     

判断与决策中的投射偏差

投射偏差是指个体常常会高估未来偏好与当前偏好的一致性, 从而把当前偏好投射到未来的心理倾向性。本文从情感–认知加工、时间修正和心理模拟等视角对投射偏差的心理机制进行了解释, 并概括出投射偏差的内源性(含内脏感觉、情绪状态和需要)和外源性(含事件相关信息、天气状况和选择情境)影响因素, 还总结归纳出投射偏差的三种应对策略, 最后指出了投射偏差在未来研究的方向。     

不同时间关注点下的空间-时间联合编码效应

摘 要 本研究旨在探讨时间关注特征对空间-时间反应编码联合效应的影响。采用时间关注点量表将有效被试分为关注过去组和关注未来组,进行反应区分实验。实验代表过去或未来的时间词作为启动刺激,要求被试判断的目标刺激是随后出现在屏幕左或右侧的圆点。结果发现,关注过去的个体对“左/过去词”的反应更快,关注未来的个体对“右/未来词”反应更快。表明时间关注点影响人们的空间-时间联合编码效应,不同的时间关注点产生人们对于过去和未来时间在注意分配上的差异,从而表现出不同的空间表征方式,在“左-右”水平轴上验证了时间关注点假设。     

Robust memory of where from way back when: evidence from behaviour and visual attention

Retention of events typically exhibits a sharp initial decrease followed by levelling off of forgetting. In an apparent exception to this general rule, college students have robust memory for their own locations in obscured versions of photographs of their entering classes taken during orientation-related activities, whether tested 2 months or 42 months after the event. Experiment 1 of the present research was a test for conceptual replication of this finding in photographs depicting more than twice the number of students (and thus potential distracters). There was no difference in memory accuracy for personal spatial location across retention intervals of 6–30 months. Experiment 2 featured 40-h and 2-month retention intervals, thereby providing a more fine-grained test of the forgetting function. The findings replicated Experiment 1. In Experiment 3, eye-tracking measures of visual attention revealed that participants rapidly fixated their own spatial locations within the photographs, even in the absence of explicit awareness. In all three experiments, memory for temporal features of the orientation activities (e.g., day and time the photograph was taken) followed the typical forgetting function. The findings suggest differential preservation of episodic memory for where relative to other aspects of events and experiences, such as when.     

Time manages interference in visual short-term memory

Emerging evidence suggests that age-related declines in memory may reflect a failure in pattern separation, a process that is believed to reduce the encoding overlap between similar stimulus representations during memory encoding. Indeed, behavioural pattern separation may be indexed by a visual continuous recognition task in which items are presented in sequence and observers report for each whether it is novel, previously viewed (old), or whether it shares features with a previously viewed item (similar). In comparison to young adults, older adults show a decreased pattern separation when the number of items between “old” and “similar” items is increased. Yet the mechanisms of forgetting underpinning this type of recognition task are yet to be explored in a cognitively homogenous group, with careful control over the parameters of the task, including elapsing time (a critical variable in models of forgetting). By extending the inter-item intervals, number of intervening items and overall decay interval, we observed in a young adult sample (N?=?35, M_age?=?19.56 years) that the critical factor governing performance was inter-item interval. We argue that tasks using behavioural continuous recognition to index pattern separation in immediate memory will benefit from generous inter-item spacing, offering protection from inter-item interference.     

The role of white matter hyperintensities and medial temporal lobe atrophy in age-related executive dysfunctioning

Various studies support an association between white matter hyperintensities (WMH) and deficits in executive function in nondemented ageing. Studies examining executive functions and WMH have generally adopted executive function as a phrase including various functions such as flexibility, inhibition, and working memory. However, these functions include distinctive cognitive processes and not all may be affected as a result of WMH. Furthermore, atrophy of the medial temporal lobe (MTA) is frequently observed in ageing. Nevertheless, in previous studies of nondemented ageing MTA was not considered when examining a relationship between white matter and executive function. The goal of the present study was to examine how WMH and MTA relate to a variety of executive functions, including flexibility, fluency, inhibition, planning, set shifting, and working memory. Strong correlations were observed between WMH and MTA and most of the executive functions. However, only MTA was related to flexibility and set shifting performance. Regression analysis furthermore showed that MTA was the strongest predictor of working memory, after which no further significant association with WMH was noted. Alternatively, both MTA and periventricular hyperintensities independently predicted inhibition performance. These findings emphasize the importance of MTA when examining age-related decline in executive functioning.     

生态心理学——心理学研究模式的转向

生态心理学是西方心理学的一种新取向,它在方法论上倡导将交互作用原则作为主要研究原则,具体来说,就是主张实际生活环境的研究原则、多元方法选择原则、多元交互解释原则,这些原则带来了心理学研究模式的转向：从探讨思辨中或实验室中的心理向探讨真实环境中的心理转变;从人的心理内部机制的探求转向对人和环境互动关系的探求;从对理论模型的追问到对理论背景与实验设计之间匹配的关注;从分析性思维模式为主转向综合性思维模式。
