Correlation between inspection time and psychometric abilities: A personal interpretation

More than 25 years of research suggests that the measure inspection time (IT) does capture low-level aspects of cognitive functioning that contribute to human intelligence. However, recent evidence does not support earlier claims that IT estimates the speed of a single mechanism like “sampling input” or “apprehension.” Rather, together with other tasks that employ pattern backward masking to limit the duration for which information is available for processing, IT is probably sensitive both to focused attentional capacities to detect organization and change under severe time constraints and to decision processes, ongoing beyond mask onset, that monitor responding. Among normal young adults, IT is correlated with the broad psychometric factor Gs (“speediness”). This mediates correlation with general intelligence. In this group, IT is not correlated with Gf. However, whether this outcome generalizes to samples of persons with an intellectual disability, to young children, or to elderly persons is not yet known. Psychological processes underpinning IT are currently only speculatively defined, but it should prove possible to unravel these by experimentation. To this end, backward masking procedures are arguably more theoretically tractable than reaction time tasks because they reduce the impact of higher-level cognitive strategies on performance. On this basis, IT may hold promise as a means for developing partial explanations for intelligence in psychological terms. However, whether this is realized depends on identifying the psychological functions that support IT.     

Fixed-time schedule effects as a function of baseline reinforcement rate

Using an arbitrary response, we evaluated fixed-time (FT) schedules that were either similar or dissimilar to a baseline (response-dependent) reinforcement schedule and extinction. Results suggested that both FT schedules and extinction resulted in decreased responding. However, FT schedules were more effective in reducing response rates if the FT reinforcer rate was dissimilar to baseline reinforcer rates. Possible reasons for this difference were evaluated with data analysis methods designed to identify adventitious response-reinforcer relations.     

健康领域的跨期决策与健康行为

健康领域的跨期决策关系着个体和国民的健康和福祉。目前学界对该领域的研究主要停留在参考传统金钱领域的相关理论模型和方法的阶段, 但健康跨期决策具有领域特异性, 沿袭金钱领域理论模型和方法, 导致该领域在研究方法和结果上存在较大的不一致性。健康跨期决策的行为后果是该领域关注重点, 多数研究均报告个体的低时间折扣率、高未来时间取向与其健康保护行为正相关, 与健康风险行为呈负相关。该领域也关注健康跨期决策的影响机制, 如决策对象和决策主体的核心特征等因素。未来研究亟需发展适用于健康领域的跨期决策模型和研究范式, 明确健康行为与跨期决策偏好的关系, 深入探讨健康跨期决策的内在选择机制, 并在健康行为干预和医疗卫生政策应用方面进行更多的尝试和探索。     

社会认知基本维度与主观幸福感：未来时间洞察力的中介作用

基于社会认知双视角模型和人类适应机制,探讨能动性和表达性与主观幸福感的关系及其作用机制,采用社会认知基本维度形容词词库、未来时间洞察力问卷和幸福感指数量表对全国21个省市居民进行调查,共回收有效问卷4071份,其中男性1714人（42.1%）,女性2342人（57.5%）。结果表明：（1）能动性、表达性显著正向预测主观幸福,且能动性的预测效力大于表达性;未来时间洞察力显著正向预测主观幸福感;（2）能动性、表达性能通过未来时间洞察力的中介作用间接预测个人主观幸福感。本研究结果有利于揭示能动性、表达性如何影响个体主观幸福感体验,以及能动性、表达性对主观幸福感的影响程度,对于提升个人主观幸福感有一定启示意义。     

父亲参与教养状况对学前儿童社会技能的作用

作为孩子成长的关键人物之一,父亲对儿童早期的社会性发展具有重要作用。本研究以184名学前中班儿童及其父母为被试,考察父亲参与教养的量(参与教养的时间)和质(积极教养行为)对儿童早期社会技能的作用。结果发现:(1)控制母亲积极教养行为以后,父亲参与教养时间仍显著预测儿童的社会技能,父亲积极教养行为的预测作用不再显著。(2)控制母亲积极教养行为后,父亲参与教养时间显著预测女孩的合作性、责任感、自我控制及总体社会技能,边缘显著预测男孩的主张性;父亲积极教养行为边缘显著预测男孩的主张性,对女孩各项社会技能的预测均不显著。(3)父亲参与教养时间显著预测母亲积极教养水平低组儿童的合作性、主张性、责任感、自我控制及总体社会技能,父亲积极教养行为边缘显著预测母亲积极教养低组儿童的合作性和总体社会技能。表明父亲参与教养对母亲消极教养具有缓冲作用,其中父亲参与教养时间的缓冲效应更明显。     

判断与决策中的情感启发式

情感启发式是指在判断与决策的过程中,个体会有意识或无意识的利用自己对任务选项的主观情感反应来做出决策。具体来说,个体头脑中物体和事件的表征会激起不同水平的情感体验,这种不同的体验会对所有的表征做出积极或消极的标记,人们根据这些被标记的体验来做出判断和决策。情感启发式是个体在决策中常用的策略。目前,关于情感启发式心理机制的解释主要有情感启发式模型和双加工理论。此外,情感启发式的影响因素主要包括经验、时间压力、可评估性和计数能力等。未来的研究应主要集中在探究情感启发式的产生根源和进一步扩展情感启发式应用领域的研究。     

未来时间的心理结构

２２０名大学生被试用秒、分、小时、日、星期、月和年７个时间单位和模糊统计试验方法对３９个不定的未来时间修饰词作经验赋值,结果表明：①３９个不定的未来时间修饰词与秒、分、小时、日、月、年有一定的对应关系,②未来的心理时间分为三个时间段,即以秒和分为计时单位的“较近的未来”,以小时、日和月为计时单位的“近的未来”,以及以年为计时单位的“远的未来”。③离现在越近的未来时间修饰词,词义模糊度越小,评量的把握度越大;而离现在越远的未来时间修饰词,词义模糊度越大,评量的把握度越小。     

Reasoning and concurrent timing: a study of the mechanisms underlying the effect of emotion on reasoning

Negative emotions typically have an adverse effect on reasoning, especially analytic or logical reasoning. This effect can be explained using an attentional framework in which emotion detracts limited-capacity cognitive resources which are required for reasoning. Another possibility is that the effect of emotion on reasoning is mediated by arousal, as previous research has shown that physiological arousal can be associated with decreased reasoning performance. In this research, we used a dual-task paradigm combining a syllogistic reasoning task and a time production task. Prospective timing allows to disentangle the effects of attention and arousal: time productions should lengthen if emotion takes up cognitive resources that are therefore not available for timing, whereas time productions should shorten if emotional reasoning results from increased arousal. Results from two experiments confirm the adverse impact of emotion on logical reasoning performance. Reasoning about emotional contents led to lengthened time productions, which suggests that the capture of limited cognitive resources is the main factor accounting for the adverse effect of emotion on reasoning and not arousal.
