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。     

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。     

材料呈现方式对不同音乐训练经验的汉语儿童英语言语记忆的影响

选取受过音乐训练和未受过音乐训练的汉语儿童为被试,在同一呈现速率条件下以歌曲、韵律和朗读三种方式呈现一段英文材料,从单词、句子和篇章三个层面探讨音乐训练经验和材料呈现方式对第二语言言语记忆的影响。结果发现：1）音乐组的记忆成绩高于非音乐组;2）相比于朗读材料,儿童对于歌曲和韵律材料的记忆效果更好;3）在单词和句子层面,音乐组和非音乐组的差异主要体现在歌曲材料上,而篇章层面没有类似发现。该结果表明音乐训练和材料呈现方式均能影响儿童的第二语言言语记忆,并且音乐训练效应对材料呈现方式表现出选择性     

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.     

itsme: Interaction Design Innovating Workstations

Background  In the last 30 years, there has been little innovation in workstations. The desktop metaphor has become the standard user interface, with its pros (e.g., ease of learning) and cons (e.g., interaction constraints for skilled users, lack of context awareness). Objectives  In this paper, we present itsme, an Italian initiative to design the next-generation workstation. Interaction design is the basis of the project, as well as the involvement of a wide community of contributing users. Results  The early design phases of the project led to the definition of a new metaphor for personal computing, based on stories and venues. The metaphor is being adopted for the development of a novel front-end for the Linux operating system, aimed at fulfilling the needs and desires of knowledge workers.

Enhancing early communication through infant sign training

Existing research suggests that there may be benefits to teaching signing to hearing infants who have not yet developed vocal communication. In the current study, each of 4 infants ranging in age from 6 to 10 months was taught a simple sign using delayed prompting and reinforcement. In addition, Experiment 1 showed that 2 children independently signed in a variety of novel stimulus conditions (e.g., in a classroom, with father) after participating in sign training under controlled experimental conditions. In Experiment 2, crying and whining were replaced with signing when sign training was implemented in combination with extinction.     

不同呈现方式的网页广告的眼动研究

选择25名视力正常的大学生,用眼动仪记录他们浏览不同呈现方式、不同位置的网页广告的眼动过程。结果发现：1．对于不同呈现方式的网页广告,从记忆成绩看：彩色组显著优于黑白组,两者与动画组没有显著差异;从眼动指标看：动画组和彩色组的注视次数和注视时的明显高于黑白组。2．网页广告的位置对被试的记忆成绩与眼动模式有一定的影响,表现为上部与中部注视次数增加,注视时间长。记忆成绩也表现为差异显著,中部与上部的记忆效果好。     

Functional visual field in a rapid serial visual presentation task

Dynamic temporal change in the size of functional visual field was measured using a dual task: a peripheral task in which one square in a background pattern of squares was changed in shape to a dot; and a central task involving the rapid serial visual presentation of a sequence of letters (RSVP task). The temporal lag between the occurrences of the dot and the RSVP target was manipulated. University students were asked to detect the dot and to depress a mouse button as quickly as possible while searching for the RSVP target among a sequence of distracter letters. The abrupt change in the shape of a background square in the peripheral task caused a processing deficit in the RSVP task at relative lags from –3 to –1 (255 ms to 85 ms before presentation of the RSVP target), but the encoding and retaining processes involved in identifying the RSVP target did not impair the detection of the peripheral dot. The functional visual field was found to expand while participants were performing the dual task, suggesting that preattentive detection is affected by general attentional activity.     

等待是一种折磨？等待时间知觉及其导致的非理性决策行为

等待时间知觉是指人们在等待过程中对等待时长的主观感受和心理体验, 它对人们的决策行为产生影响。影响等待时间知觉的客观因素包括等待过程的填充物、等待时间的确定性、接受服务的阶段和等待的物理环境等; 主观因素有负性情绪、自我控制和人格因素等。等待时间知觉导致的非理性决策行为包括时间沉没成本效应、“延迟-提前”框架效应、峰-终效应、偏好反转等。未来研究可从三个方面开展：(1) 时间启动和金钱启动下等待时间知觉的差异; (2) 基于时间心理账户视角研究等待时间知觉规律; (3) 借鉴时间知觉理论探讨等待(时间)影响决策行为的心理机制。     

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.
