轻度阿尔茨海默症患者的前瞻记忆

轻度阿尔茨海默症往往伴随着不同程度的前瞻记忆衰退。已有研究以轻度阿尔茨海默症与前瞻记忆衰退的关联程度为主线, 对比了这一关联与“其他认知缺陷疾病-前瞻记忆衰退”、“轻度阿尔茨海默症-回溯记忆衰退”以及“轻度阿尔茨海默症-遗传表达”这三种关联的类似程度。此外, 也有研究涉及到了如何促进轻度阿尔茨海默症患者的前瞻记忆。将来的研究应引入病情程度、前瞻记忆任务类型等变量, 深入探讨轻度阿尔茨海默症与前瞻记忆衰退的关联, 并使用ERP、fMRI等神经生理技术确定轻度阿尔茨海默症患者前瞻记忆衰退的机制。     

一种混合型前瞻记忆的干扰效应的神经机制

采用3（任务类型）×2（时段）被试内实验设计,对比一种混合型前瞻记忆（MPM）和基于事件的前瞻记忆（EBPM）在不同时段对进行中任务的干扰效应的神经机制。结果表明,在目标出现的时段,MPM对进行中任务有干扰效应,额区电极最活跃,额区电压最高,而在非目标时段MPM无干扰效应,但刺激出现后200-300ms额区电极较活跃。说明前瞻记忆任务在大脑中可能处于较高的激活状态,额叶灵活地调配意识的不同状态在前瞻记忆加工中参与的程度和时段。     

The effect of personality variables in the prediction of the execution of different prospective memory tasks in the laboratory

The study of prospective memory (ProM), the remembering of the delayed execution of intentions, has been growing in recent years, and we know quite a bit about the cognitive variables that affect it. But the performance of a task depends on personality variables as well as on cognitive ones, and the role of personality variables in ProM has only been partially studied, the results being less conclusive. We sought to address two main objectives: (1) to quantify the joint influence of cognitive and personality variables on three ProM tasks in the laboratory (two based on events and the other on time), and (2) to identify the personality profiles of those who perform well in these three ProM tasks as opposed to those who do not. The cognitive and personality variables were evaluated with two sessions of 157 participants. The 16 PF-5 was applied (Cattell, Cattell & Cattell, 1993) and other cognitive variables were measured. With the data obtained, we ran several regression analyses to determine how some cognitive variables (sustained attention, verbal fluency, interference, retrospective memory, selective attention) and personality factors (tested using the 16 PF-5) can help to explain the variance in the performance of prospective memory tasks. Our results show that the contribution of personality predictor variables is moderate and smaller than that of the cognitive variables for predicting the execution of ProM tasks in the laboratory. Furthermore the intervention of the personality variables differs depending on the ProM tasks used. Global self-control and rule-consciousness were the personality variables that contributed the most in the prediction of the scores in the ProM tasks that were used.     

On the Fulfillment of Moral Obligation

This paper considers three general views about the nature of moral obligation and three particular answers (with which these views are typically associated) concerning the following question: if on Monday you lend me a book that I promise to return to you by Friday, what precisely is my obligation to you and what constitutes its fulfillment? The example is borrowed from W.D. Ross, who in The Right and the Good proposed what he called the Objective View of obligation, from which he inferred what is here called the First Answer to the question. In Foundations of Ethics Ross repudiated the Objective View in favor of the Subjective View, from which he inferred a Second Answer. In this paper each of the Objective and Subjective Views and the First and Second Answers are rejected in favor of the Prospective View and a Third Answer. The implications of the Prospective View for another question closely related to the original question are then investigated: what precisely is your right regarding my returning the book and what constitutes its satisfaction?     

精神分裂症患者的前瞻记忆比较研究

近年来有越来越多的心理学家从神经心理学角度对前瞻记忆进行研究,其中涉及较多的是正常被试与脑损伤患者之间的前瞻记忆比较。本文则针对目前关注比较少的精神分裂症这种特殊的脑损伤病人,通过对28名精神分裂症患者与30名正常被试在一定试验条件下进行前瞻记忆研究,试图发现其与正常被试在前瞻记忆的水平、影响因素以及自我评价方面的差异并分析其原因。     

幼师生职业决策自我效能感问卷的初步编制

以344名幼儿师范学校的学生为被试,检验了自编《幼师生职业决策自我效能感问卷》的信效度,同时考察了幼师生职业决策自我效能感的特点。结果显示:(1)《幼师生职业决策自我效能感问卷》具有良好的结构效度和效标效度;(2)对幼师生职业决策自我效能感的方差分析发现,生源地与年级的主效应不显著;(3)喜欢幼师专业与否的主效应显著,平均数比较发现,喜欢幼师专业的学生在职业决策自我效能感及其五个维度上的得分都显著地高于不喜欢幼师专业的学生;(4)生源地与年级、生源地与对幼师专业的兴趣以及年级与对幼师专业的兴趣的交互作用均不显著。     

12-20岁个体前瞻记忆的发展与影响因素的研究

以334名12～20岁个体为被试,采用两因素混合设计,探讨这一年龄阶段个体前瞻记忆的发展及影响因素。结果发现,被试前瞻记忆水平随年龄增长而提高,且在14～16岁发展最快;提高基于时间的前瞻记忆负载,会使前瞻记忆成绩降低;前瞻记忆与当前任务的完成呈负相关。表明前瞻记忆是一种策略加工过程。     

MEMORY ALTERING TECHNOLOGIES AND THE CAPACITY TO FORGIVE: WESTWORLD AND VOLF IN DIALOGUE

I explore the impact of memory altering technologies in the science fiction drama (2016–2020) in order to show that unreconciled altered traumatic memory may lead to a dystopian breakdown of society. I bring Miroslav Volf's theological perspectives on memory into conversation with the plot of Westworld in order to reveal connections between memory altering technologies and humanity's responsibility to remember rightly. Using Volf's theology of remembering as an interpretive lens, I analyze characters’ inability to remember rightly while recalling partial memories of their trauma. In virtue of this examination, I contend that memory altering technologies may inhibit individuals from relational processes of healing, such as forgiveness. Consequently, I argue that this study leads to a richer understanding of the potential that memory altering technologies have for undermining humanity's ability to interact in a relational capacity, specifically in terms of forgiveness.     

The effects of empathy on search efforts for missing persons

People have difficulty sighting missing persons, partially because people's limited cognitive resources are required for searching. As a result, people sometimes do not devote resources to searching. This research will examine whether empathy increases the resources devoted to searching and search performance. In Experiment 1, we will manipulate empathy toward a formerly missing person and measure willingness to volunteer to search and actual search performance. In Experiment 2, we will manipulate empathy felt toward a missing person. We will measure the time participants spend studying the missing person's photograph. We hypothesize that participants induced to feel empathy will indicate more willingness to search (Exp 1 & 2), put more effort toward searching (Exp 1), and spend more time studying the photograph (Exp 2) than those not induced to feel empathy. If empathy increases search effort and performance, it could be induced in actual missing persons cases to increase recovery rates.     

Intraindividual reaction time variability predicts prospective memory failures in older adults

This study investigated the relationship between intraindividual variability (IIV) in reaction time and prospective memory errors in older adults using data from the Zurich Longitudinal Study of Cognitive Aging (n = 336 individuals aged 66–81 years). The results indicated that increased IIV measured from independent tasks was associated with a greater proportion of prospective memory errors. These significant findings were not influenced by age and did not vary according to prospective memory cue type. Variability is thought to reflect fluctuations in attentional and executive control and these attentional processes may also impact on prospective memory through failure to detect the target cue. The findings suggest, therefore, that measures of variability may have some potential in the identification of older persons who are more vulnerable to everyday errors such as prospective memory failures.
