推理与决策的双加工理论研究简评

决策与推理的双加工理论是一个颇有影响力的理论,通过对两个加工系统的基本特点、区别点以及基本关系、推理错误原因等几个方面进行分析阐述,发现目前在该理论的一些基本问题的认识上还存在诸多问题。主要表现在以下几方面：（1）两个加工系统的关键区别点不在于工作记忆有无绝对参与;（2）对于推理和决策错误的原因,不同的双加工理论给出了不一致的解释;（3）今后有待从情绪与推理决策的关系、影响等方面加深对推理与决策错误的理解     

面孔再认及学习程度判断中的同龄效应

同龄效应指个体对自己年龄段面孔的记忆成绩显著高于其他年龄面孔.实验采用3×3混合设计,考察不同年龄被试对面孔再认及学习程度判断中的同龄效应,探讨同龄效应的发展规律.结果显示,青年和老年人对同龄面孔的再认显著好于异龄面孔,儿童对同龄与异龄面孔的再认成绩差异不显著;各组被试对不同年龄的面孔学习程度判断准确性之间的差异没有区别.这表明:青年和老年人在面孔再认中出现了同龄效应,儿童没有表现出同龄效应;个体学习程度判断中不存在同龄效应,且这种特点与年龄无关.     

工作记忆负荷和自动化提取对小学生加法心算策略执行效果的影响

本研究选取43名小学四年级学生(18名男生和25名女生)为实验被试,探究了工作记忆负荷和自动化提取对复杂加法心算策略效果的影响.结果显示:(1)工作记忆负荷对复杂加法心算策略的影响显著,即一项加法心算策略所需的工作记忆负荷越小,该策略的执行效果越好;(2)自动化提取对加法心算策略的影响显著,即一项加法心算策略所需自动化提取的程度越高,该策略的执行效果越好;(3)工作记忆负荷和自动化提取对加法心算策略效果的交互作用显著,表现为在自动化提取水平较高的情况下,工作记忆负荷的大小对心算策略执行效果的影响差异不显著;而在自动化提取水平较低的情况下,工作记忆负荷小的心算策略的执行效果显著优于工作记忆负荷大的心算策略的执行效果.     

Incertitudes au cours de la carrière et construction des perspectives temporelles

The increasing uncertainty context, in which individuals' professional paths are taking form today, is the occasion to a critical renewal of career course analysis models. In the first part of the article, we argue with the model propounded by Power and Rothausen (2003), which aims to analyse and support mid-career professional orientation behaviours, by extending the Super's career maintenance stage. We partly break free with them, defending the conception of an active socialisation, which analysis of orientation behaviours is based on the conjoined study of temporal perspectives and of exchanges between life domains. This point of view is supported by results from a research dealing with future temporal perspectives reconstruction processes of individuals confronted with the unemployment uncertainty. They show that individuals do not project in the future only by striving for yielding “employable”. Their projects do not only result from the rational control of the information related to the anticipated professional environment. Ascribed to peculiar paths, those projects summon up processes of values confrontation and comparisons with others, in the plurality of individuals' life fields.     

Syntactic transfer in artificial grammar learning

In an artificial grammar learning (AGL) experiment, participants were trained with instances of one grammatical structure before completing a test phase in which they were required to discriminate grammatical from randomly created strings. Importantly, the underlying structure used to generate test strings was different from that used to generate the training strings. Despite the fact that grammatical training strings were more similar to nongrammatical test strings than they were to grammatical test strings, this manipulation resulted in a positive transfer effect, as compared with controls trained with nongrammatical strings. It is suggested that training with grammatical strings leads to an appreciation of set variance that aids the detection of grammatical test strings in AGL tasks. The analysis presented demonstrates that it is useful to conceptualize test performance in AGL as a form of unsupervised category learning.

Adolescents’ Change in Motivation as a Result of Buddhist Education: How Does It Make a Difference in Their Learning Outcomes?

Motivation significantly influences students’ learning outcomes. Changing their learning motivation improves their performance. This study used an exploratory sequential mixed methods approach, with the participation of 140 adolescents attending retreats at three Zen monasteries belonging to the Truc Lam (Bamboo Forest) Zen sect, to examine how they changed their motivation, what made them change, and how the change improved their learning outcomes. The study also evaluated the effect of gender and age on changes in motivation. The results indicated that many teenagers had changed from extrinsic to intrinsic motivation thanks to Dharma lessons, teacher support, and leisure activities. Compared to students who maintained their extrinsic motivation unchanged, they had better learning outcomes. Age, but not gender, had a considerable effect on changes in teenagers’ motivation. These findings provide more evidence for extending Buddhist education and conducting further research on young Buddhist learners’ motivation in various contexts.
