输出方式和输出时间对数字广度的影响

实验目的是探讨在不同的输出方式下,输出时间对短时记忆的影响是否相同。在数字广度实验中,给被试呈现单个数字组成的数字串,要求被试分别采用口头和书写两种输出方式来报告不同的内容：直接报告刺激呈现的单个数字串,以及在每个数字前附加不同长度的字符报告。结果发现附加字符使口头和书写的输出时间都增加。但在口头报告中,输出时间增加的同时伴随着记忆成绩下降,而书写报告的记忆成绩不受影响。讨论了此结果的意义,推测输出阶段中影响记忆成绩的可能是发音时间,而不是延迟时间。     

米契尔关于满足延宕的研究

满足延宕是非常重要的自我控制行为,本文主要介绍米契尔在这方面的研究,涉及到了满足延宕的研究模式、影响个体做出延宕选择的因素、注意转移和认知表征对延宕过程的影响、儿童关于延宕的元认知发展、早期延宕行为与多年后个体的认知能力、社会应对技能的相关性研究、双重系统结构的理论,并分析了米契尔的研究对当今儿童教育的启示。     

The Effects of Social Status and Culture on Delay Discounting

People generally tend to discount future outcomes in favor of smaller but immediate gains (i.e., delay discounting). This study examines the hypothesis that culture and social status moderate this tendency, as well as the alternative hypothesis that social status and culture influence delay discounting independently of each other. American and Japanese adults were asked to choose receiving hypothetical monetary rewards either immediately or receiving rewards of different amounts with a delay of 1 year. The results replicated previous findings and supported the alternative hypothesis. Delay discounting was lower when subjective socioeconomic status (i.e., an individual’s perception of her or his social rank) was higher. Also, the Japanese were less likely to discount future rewards than the Americans. However, there was no interaction between social status and culture in influencing the rates of delay discounting.     

婴儿指示性手势与其语言学习的关系

指示性手势是指明空间中某个物体、处所或事件的手部动作,在婴儿1岁时出现,与婴儿的语言学习存在着较强的相关,然而目前尚不清楚为什么会存在此相关。可能存在两种内在机制:(1)指示性手势影响婴儿的学习环境——引发了适时的语言输入;(2)影响学习者本身——帮助婴儿创造有效的学习状态并示意给他人。未来的研究需要探讨这两种机制如何交互作用,以及如何将指示性手势作为诊断或干预工具,用于识别和帮助有语言障碍风险的个体。     

ALTERING THE MAGNITUDE OF DELAY DISCOUNTING BY PATHOLOGICAL GAMBLERS

The present study explored the delay discounting of future and past monetary rewards by pathological gamblers. Using a multiple baseline design, following repeated exposure to choices between smaller immediate and larger delayed consequences, participants completed a relational responding task that attempted to alter the psychological functions of irrelevant stimuli and to affect subsequent delay discounting. Results support previous literature on the discounting of delayed consequences by pathological gamblers, illustrate that the discounting of past rewards occurs in a similar fashion to the well‐documented literature on the discounting of future rewards, and that magnitude of discounting can be altered.     

Including Manual Signing as Nontargeted Information When Using a Constant Time Delay Procedure to Teach Receptive Identification of Packaged Food Items

This investigation extends the constant time delay research base by embedding nontargeted information in the task direction when teaching communication skills. Specifically, instructors taught receptive identification of packaged food items to 4 secondary students with moderate to severe disabilities and evaluated generalization to the community. In addition, instructors included the manual sign for each food item. The instructional strategy was a constant time delay procedure using a 5-s delay interval. The intervention, conducted within a multiple probe design across behaviors replicated across students, resulted in the acquisition and generalization of receptive identification of packaged food items by 3 out of 4 of the students. In addition, the students acquired the nontargeted manual signs with an average of 60% percent in the final probe session.     

职业延迟满足研究述评

职业延迟满足强调人们为了实现长期职业目标, 克服职业生涯中即时满足的冲动和诱惑的选择倾向, 并为审视和解释个体职业生涯发展提供了新的视角。国外研究者一般从工作伦理的范畴来考察职业延迟满足, 而在中国, 职业延迟满足则成为一个明确的组织行为学概念得以发展。虽然国内外研究者从个体、组织和社会等多个层面考察了职业延迟满足的相关因素及其效果, 但由于该领域的研究起步较晚, 现有研究并不深入。未来应重点关注职业延迟满足的本土化研究、概念发展、测量方法的改进, 并纵向研究其对个体职业成长的影响机制与效果。     

回溯式时距估计的动态性及心理机制

时间流逝过程中, 回溯式时距估计动态性体现在短时延迟和长时发展两个方面。前者聚焦秒、分级的延迟, 将其归为背景变化或由目标时距引发的认知差异; 后者聚焦跨年龄(如婴儿、儿童到成年)的个体发展, 认为主要是信息加工速度的差异。最后, 从综合视角出发, 认为其动态性可能是由不同时距信息心理表征的差异造成的, 这体现时间认知的分段综合性。未来需以时间流逝的动态视角开展回溯式时距估计的心理表征研究, 深入探讨与目标时距紧密相关的计时策略在回溯式时距估计中的作用, 并扩展年龄、人格类型等个体差异方面的动态特征研究。     

Effects of delayed time‐out on problem behavior of preschool children

Time‐out is a common negative punishment procedure in home and school settings. Although prior studies have shown time‐out is effective, more research is needed on its effects when implementation is imperfect. We evaluated delays to time‐out with 4 preschool children who engaged in some combination of aggression, property destruction, and rule breaking. Target behavior decreased for all subjects exposed to delayed time‐out, with 3 of 4 subjects displaying low levels of target behavior even when time‐out was delayed by 90‐120 s. These data suggest delayed time‐out might be effective in situations in which a caregiver or teacher cannot implement time‐out immediately.
