小学儿童学习时间分配决策水平的发展

利用自由回忆,线索回忆和再认三种提取方式,以儿童任务难度预见（EOL）的判断等级与学习时间分配之间的G相关值作为指标,考察了小学儿童学习时间分配决策水平的发展过程。小学2、4、6年级儿童和成人大学生(作为对照)参与本研究,每个年龄组各24人。主要研究结果表明：（1）总体而言,小学各年级儿童,其学习时间分配的决策都受对任务难度预见等级的制约,对EOL判断等级越高的项目,分配的学习时间越长,说明小学儿童具有一定程度的学习时间分配的决策能力;（2）在自由回忆条件下,小学4年级和小学6年级儿童对EOL的判断等级与学习时间之间的G相关值差异显著,表明儿童的决策水平由小学4年级到小学6年级表现出快速发展的趋势;（3）在线索回忆的条件下,小学2年级和4年级儿童G相关值有显著差异,表明决策水平由小学2年级到小学4年级之间有快速发展的趋势;（4）在再认的条件下,小学各年龄儿童学习时间分配的决策水平没有显著性差异,表明再认条件下小学阶段的决策水平进步不显著;（5）在三种提取方式下,小学儿童对任务难度预见判断等级与首次学习时间之间的G相关值都不同程度地低于与总的学习时间之间的相关值。这说明小学儿童在反复学习的过程中在不断调整自己的学习时间分配,调整的程度有随年龄增长而加大的趋势。小学6年级儿童在任务难度预见判断等级与学习时间之间的G相关值已接近成人水平。     

不同任务定向下小学儿童学习时间分配决策水平的发展

研究包含3个实验,分别探查了儿童在“速度定向”、 “准确性定向” 以及“速度和准确性定向”3种任务定向下学习时间分配决策水平的发展。3个实验均采用3×3混合设计,选择小学2年级、小学4年级、小学6年级学生各24人为被试,提供难度不同的3种材料,考查在限定的时间内儿童在3种材料间进行的学习时间分配决策水平的发展。结果：（1）在三种任务定向下,儿童学习时间分配决策水平均随年龄增长而提高。（2）不同的任务定向要求对不同年级儿童学习时间分配决策的影响不同。（3）在本实验条件下,儿童学习时间分配策略的使用,经历了三个阶段：第一个阶段,不使用策略;第二个阶段,使用策略但效果不稳定;第三个阶段,使用策略且有稳定效果     

不同时间限制下小学儿童学习时间分配决策水平的发展

采用3×3二因素混合实验设计,利用计算机呈现刺激并记录被试的反应,以语意联系密切程度不同的词对作为难易不同的材料,借助线索回忆作为提取方式,利用四项研究分别探查小学儿童在短时限、中等时限和无时限三种时间限制下,学习时间分配的发展特点和趋势。得到如下结论：（1）小学各阶段儿童在学习过程中,主动进行了学习时间分配的决策。（2）儿童学习时间分配的决策水平随年龄增长而提高。（3）不同的时间限制难度不同,儿童在不同的难度任务下选择了不同的掌握标准,进行了不同的时间分配,支持了“标准影响分配假说”。（4）随着年龄增长,儿童的提取正确率有增加的趋势,时限越长,提取正确率越高。     

学习困难儿童元记忆能力的实验研究

该研究以有和无意义联系的两种中文词对为材料,采用2×3×2混合实验设计,对小学三到五年级的学习困难儿童与学优儿童的JOL监测判断水平和学习时间分配之间的差异及其发展特点进行研究。结果表明：（1）学习困难儿童的JOL判断等级显著低于学优儿童;（2）在自定步骤学习过程中,随着年级增长,学习困难儿童能够根据学习材料的性质决定其学习时间的分配策略,表现出一定的元记忆控制能力,但其分配策略的有效性不高;（3）学习困难儿童的JOL监测判断水平和学习时间分配策略从小三到小五在缓慢提高;（4）学习困难儿童的JOL监测判断和学习时间分配之间存在交互影响。     

儿童学习时间分配决策能力发展的研究进展

学习时间分配的研究进行了将近40年,而对儿童学习时间分配的发展研究也走过了近40年的历史。从最初的他控步调的学习到后来的自控步调的学习,从关注学习材料的难度这一外部线索到关注学习者内部的活动机制,从讨论学习时间分配活动本身到探讨影响学习时间分配发展的各种因素,对于学习时间分配发展的研究始终在不断深入。文章从上述视角,对学习时间分配的新近研究进行了总结。并对今后的研究趋势进行了展望。     

自定步调学习时间的习惯性反应：来自眼动的证据

习惯性反应指学习者根据自身阅读习惯来进行学习时间分配,它通常由词对位置这一外部线索激发。研究运用眼动记录技术,采用Metcalfe范式探讨词对位置和难度对学习时间分配的影响,以检验自定步调学习时间的习惯性反应。结果发现：（1）在自定步调总学习时间上,学习者倾向于对难度越大的项目分配越多的学习时间;（2）在前期自定步调学习进程上,当词对位置为易-中-难条件时,学习者倾向于优先在容易项目上分配较多的学习时间,接着是中等难度项目,最后是困难项目;当词对位置为难-中-易条件时,结果相反。这说明学习者的自定步调总学习时间受项目难度驱动,而前期自定步调学习时间受习惯性反应影响。     

学习时间分配的基于议程调节模型*

作为学习时间分配研究热点的基于议程调节模型认为,学习者是在学习目标的指导下,建构并执行议程来进行学习时间分配。议程即学习计划,是学习时间分配的驱动力。该模型强调学习者在自我调节学习过程中有意识的进行着学习效益最大化的权衡决策来实现学习目标,包容了以往学习时间分配的经典理论。大量的新近研究支持了基于议程调节模型,并深入地探讨了议程驱动与习惯性反应之间的关系。 未来的研究应进一步考察学习时间分配权衡过程中的意识和无意识双加工机制,探讨个体变量对学习时间分配议程建构的权衡机制的影响,并在更加生态化的情境中考察学习时间分配议程建构的权衡机制。     

学习不良儿童元记忆监测与控制的发展

采用2×3×2的混合设计,在自定步调和对项目逐项评定的学习条件下,对小学四~六年级学习不良儿童的元记忆监测与时间分配策略进行了实验研究。结果表明：在对学习材料难度的有效区分上,学习不良儿童与对照组儿童间无差异,不论学习不良组还是对照组,四年级儿童均不能对实验中配对学习材料难度性质做出明确区分,五、六年级儿童能够很好的区分学习材料难度;在学习判断水平上,五、六年级学习不良儿童均低于对照组儿童,四年级两组之间无差异;从对不同难度学习材料的时间分配来看,四年级学习不良儿童与对照组儿童分配在不同难度材料上的学习时间均无显著差别。五、六年级对照组儿童能够根据学习材料的不同难度分配不同学习时间,而且学习时间分配与难度判断之间存在显著相关。五、六年级学习不良儿童能在一定程度上根据学习材料的不同难度分配不同的学习时间,但这种时间分配与难度判断之间相关未达到显著水平,提示他们尚不能在有效元记忆监测基础上对不同难度学习材料进行合理的时间分配

惩罚对学习时间分配中决策与绩效的影响*

学习时间分配中的学习决策及其如何影响后续学习绩效是学习心理研究的重要领域。但对惩罚学习条件下,学习者是如何调整学习策略的,以及这种调整与后续学习绩效之间的关系尚不明确。本研究发现,奖励和惩罚条件下,参与者都会更多地选择高分的项目进行学习。在学习时间分配上,奖励组和惩罚组都倾向于将时间更多地分配到困难和高分的项目。但惩罚条件下参与者对低分项目的选择比例显著低于奖励条件,这表明惩罚影响学习者的学习策略。而且惩罚条件也影响低分且容易项目的学习效率。有趣的是,奖励和惩罚虽然对学习策略产生影响,却对学习绩效影响不显著,这表明在不同的学习条件下,不同的学习策略可以获得相似的学习成绩。     

项目分值对学习时间分配的影响：一种动态的过程

摘 要 研究考察了不同学习时段上,项目分值对学习时间分配的影响。结果发现: (1)分值的主效应显著,被试会选择更多的高分值项目学习, 且在高分值项目上分配更多的学习时间; (2)分值与学习时段存在交互作用,被试首先学习高分值项目,随后逐渐将学习重心转向中等分值项目,最后在临近测试前重点重学高分值项目。结果表明：学习时间分配是动态变化的,个体为了尽可能实现学习目标会在学习过程中不断调整所建构的议程。     

权力不稳定性对权力效应的逆转作用

摘 要 基于权力的趋近-抑制理论，本研究探讨权力不稳定性对权力效应产生逆转作用以及权力动机对这一逆转作用的影响。实验采用角色扮演法和真实任务角色来操纵被试的权力水平和权力不稳定性，以赌博任务中的冒险行为和金钱分配任务中的趋利行为来测量被试的权力趋近/抑制效应。结果发现：权力稳定条件下，高权力被试比低权力被试表现出更多的冒险行为和趋利行为；权力不稳定条件下则相反，低权力被试比高权力被试表现出更多的冒险行为和趋利行为。权力不稳定条件下高权力动机的高权力者相比低权力动机的高权力者倾向给自己分配更少的金额数，表现出更为明显的抑制倾向；而高权力动机的低权力者相比低权力动机的低权力者倾向于提出更高要求的金额数，表现出更为明显的趋近倾向。该研究证实了权力不稳定性对权力效应的逆转作用，而权力动机对这一逆转作用起到增强趋势。     

NATURAL SELECTION AND THE PROBLEM OF EVIL: AN EVOLUTIONARY MODEL WITH APPLICATION TO AN ANCIENT DEBATE

Abstract. Since Darwin, scholars have contemplated what our growing understanding of natural selection, combined with the fact that great suffering occurs, allows us to infer about the possibility that a benevolent God created the universe. Building on this long line of thought, I develop a model that illustrates how undesirable characteristics of the world (stylized “evils”) can influence long‐run outcomes. More specifically, the model considers an evolutionary process in which each generation faces a risk from a “natural evil” (e.g., predation, disease, or a natural disaster) subsequent to a basic resource allocation game. This allows both resource allocation and the natural evil to influence the number of surviving offspring. As the model shows, when the risk from the natural evil can be mitigated through the benevolent behavior of neighbors, the population may have increasing benevolence as a result of (1) greater risk from the natural evil and (2) a greater degree to which selfish individuals transfer resources to themselves in the resource allocation game. The main implication is that a world with evolutionary processes (in contrast to a world of static design) can allow two factors that have traditionally been considered “evils”—namely, the indiscriminate cruelty of the natural world and the capacity for humans to harm each other—to promote desirable long‐run outcomes.     

Effect of verbal messages with reminders to communicate driving situations to alter driver behavior in conditional driving automation

In conditionally automated driving, drivers are relieved of steering (hands-off), accelerating, and braking actions as well as of continuous monitoring of driving situations and the system operation status (eyes off). This enables continuously engagement in non-driving-related activities. Managing the allocation of a driver’s attention to the surrounding environment and automation status presents a major challenge in human–machine system design. In this study, we propose a verbal message with a reminder (monitoring request) to divert the driver’s attention from non-driving-related activities to peripheral monitoring under conditionally automated driving. When the system encounters events related to weather, traffic, and road geometry, it provides a verbal message pertaining to the road surroundings (e.g., “It is foggy outside”) to the driver. After three seconds, the system provides a reminder message (i.e., “Did you confirm it?”) to the driver. We explore two questions: (1) how does the message with the reminder affect the driver’s attention allocation, and (2) how does the message with the reminder affect the driver behavior in response to a request to intervene (RTI). With a driving simulator, we designed a repeated measures mixed design with a between-participant factor of “Driving condition” and within-participant factors of “Event type” and “Measurement time”. Three driving conditions were established as follows: no messages, messages without reminders, and messages with reminders. Twenty-seven drivers participated as participants in the driving simulator experiment. Results showed that the reminder message was effective in allocating the participants’ attention to the surrounding environment, and the participants took over the driving task after spending more time understanding the take-over situation in the condition of messages with reminders compared to those in the condition of no messages. We conclude that the proposed reminder message can direct drivers’ attention to the road surroundings during conditionally automated driving. In the future, we plan to design adaptive verbal monitoring requests to adjust the reminder message according to the situation.     

Retention of autobiographical memories: An Internet-based diary study

In this online study we examined the retention of recent personal events using an Internet-based diary technique. Each participant (N=878) recorded on a website one recent personal event and was contacted after a retention interval that ranged between 2 and 46 days. We investigated how well the participants could recall the content, time, and details of their recorded event. We found a classic retention function. Details of the events were forgotten more rapidly than the content and the time of the events. There were no differences between the forgetting rates of the “who”, “what” and “where” elements of the content component. Reminiscing, social sharing, pleasantness, and frequency of occurrence aided recall, but surprisingly importance and emotionality did not. They were, however, strongly associated with reminiscing and social sharing.     

L'influence de l'activation des rapports intersexes sur les choix en faveur de la famille,du travail,du bénévolat ou des loisirs personnels

The aim of this paper was to study how the activation of intersexes relations affected the choices of activities linked to “relational” or “market” individualism. Firstly, as in Marro's research (1998), stories were presented in which the protagonists, being female or male, for different reasons (personal, professional, etc.) must decide or not to modify the time allocation that they devote to various activities, such as family, work, leisure, or voluntary help. Next, the subjects had to point out which choice they would personally advise. In addition, an activation of intersexes relations was carried out. The results have shown: 1) that personal advice in favour of “relational” or “market” individualism are found in both sexes ; 2) that the activation of intersexes relations modified more personal advice of female subjects than of male subjects (then more oriented, to family and work for women, to leisure for men).
