不同回避动机强度的消极情绪对类比推理的影响

通过控制负性情绪的不同回避动机强度,采用经典四项比例式的推理任务,探究不同回避动机强度的负性情绪对类比推理的影响。研究结果发现:(1)不同回避动机强度的负性情绪(悲伤和恐惧)均会导致推理任务的正确率下降;(2)在低回避动机强度情绪(悲伤)下完成推理任务的反应时比高回避动机强度情绪(恐惧)下更长。结论:不同回避动机强度的负性情绪均会对类比推理产生消极作用,高回避动机强度的负性情绪下完成推理任务的速度更快,但正确率较低,这可能是由于注意窄化和情绪的动机强度通过工作记忆影响了推理过程。     

The Influence of Reasoning with Emergent Quantities on Students' Generalizations

This paper reports the mathematical generalizations of two groups of algebra students, one which focused primarily on quantitative relationships, and one which focused primarily on number patterns disconnected from quantities. Results indicate that instruction encouraging a focus on number patterns supported generalizations about patterns, procedures, and rules, while instruction encouraging a focus on quantities supported generalizations about relationships, connections between situations, and dynamic phenomena, such as the nature of constant speed. An examination of the similarities and differences in students' generalizations revealed that the type of quantitative reasoning in which students engaged ultimately proved more important in influencing their generalizing than a mere focus on quantities versus numbers. In order to develop powerful, global generalizations about relationships, students had to construct ratios as emergent quantities relating two initial quantities. The role of emergent-ratio quantities is discussed as it relates to pedagogical practices that can support students' abilities to correctly generalize.     

不同趋近动机强度的积极情绪对类比推理的影响——来自ERP的证据

实验采用类比推理的经典四项比例式"A:B::C:D",选择两种有难度差异的类推题目(同形、反义)作为实验任务,用情绪图片诱发情绪,采用事件相关电位(event-related potentials,ERPs)技术,探究欲求(高动机强度)、愉悦(低动机强度)和中性情绪影响类比推理的差异及脑机制。结果发现:(1)图式生成阶段:N400、P300和LNC被诱发,情绪在LNC上的主效应不显著;(2)类比映射阶段:N400和LNC成分被诱发,情绪在LNC上的主效应显著。LNC幅值:欲求情绪(高动机强度)愉悦情绪(低动机强度)中性情绪。结果表明情绪对类比推理的影响主要发生在类比映射阶段。不同趋近动机强度的积极情绪均会降低推理质量,延长推理的反应时,部分支持情绪的动机维度模型。     

The Effect of Rest Following Massed Practice of Continuous and Discrete Motor Tasks

Theories of the rest-related phenomena of reminiscence and warm-up decrement regard them as independent, being due to different factors. In this study it was found that rest following massed practice of a continuous task increased performance (reminiscence) and rest following massed practice of a discrete task lowered performance (warm-up decrement). The near-zero correlation found between the phenomena indicates that they are indeed independent and task-specific. Implications of the findings for the prediction of the effect of rest, and the fact that much motor learning and performance is task-specific, is discussed.     

Reasoning Continuously: A Formal Construction of Continuous Proofs

We begin with the idea that lines of reasoning are continuous mental processes and develop a notion of continuity in proof. This requires abstracting the notion of a proof as a set of sentences ordered by provability. We can then distinguish between discrete steps of a proof and possibly continuous stages, defining indexing functions to pick these out. Proof stages can be associated with the application of continuously variable rules, connecting continuity in lines of reasoning with continuously variable reasons. Some examples of continuous proofs are provided. We conclude by presenting some fundamental facts about continuous proofs, analogous to continuous structural rules and composition. We take this to be a development on its own, as well as lending support to non-finitistic constructionism.

Heuristic Value of Eclecticism in Theory Development: The Case of Piagetian-Vygotskian <Emphasis Type="Italic">dialogue</Emphasis> about Proportional Reasoning

Køppe’s proposition of four layers in theoretical building are used here in the exploration of a specific case of eclectic combination, the use of Piagetian and Vygotskian general approaches to the analysis of proportional reasoning as a cognitive mathematical ability. It is proposed here that the eclectic consideration of these contributions depends on the consideration of their specificity, in the sense that they highlight different aspects of the phenomenon under scrutiny, and also on the consideration of the coherence between this eclectic convergence and premises in terms of schools of thought under which each contribution is framed. We conclude proposing in accordance to S. Køppe’s proposal that eclecticism can be valuable and heuristic in theory development, but this contribution will depend largely on the effort in establishing careful relations between the four layers of theory-building.     

工作记忆对类比推理的影响

该实验采用2(类比推理类型)×6(组别)双因素实验设计来探讨工作记忆与类比推理之间的关系,尤其关注工作记忆的各个子成分对类比推理的影响。控制组的被试只需完成类比推理测验,而实验组的被试是在双任务的条件下进行实验。结果表明,工作记忆是影响类比推理的一个重要因素。在图形类比推理中,主要有视空间模板中的空间成分,语音回路中的发音成分以及中央执行器的参与;在言语类比推理中,则是视空间模板中的空间成分起主要作用。     

Development of Conditional Reasoning: A Longitudinal Study

This study examines the development of conditional reasoning within a longitudinal design. Two age cohorts were assessed each year for 3 years. One cohort began the investigation as 6th-grade students (M = 11 years, 6 months of age); the other cohort began as 8th-grade students (M =13 years, 8 months of age). At each measurement point, each participant completed 5 reasoning problems consisting of modified versions of the Wason Selection Task (Overton, 1990). Results demonstrated a significant improvement in reasoning performance for each cohort. Furthermore, participants performed better when "if-then" propositions were formulated with the antecedent phrase specifying an action and the consequent specifying a condition, than they did when the antecedent specified a condition and the consequent an action. The results are consistent with the position that the development of logical thinking moves toward the integration of inferential schemes into a systematic network, and that this network is not consistently available before adolescence.     

Generalized Processing Tree Models: Jointly Modeling Discrete and Continuous Variables

Multinomial processing tree models assume that discrete cognitive states determine observed response frequencies. Generalized processing tree (GPT) models extend this conceptual framework to continuous variables such as response times, process-tracing measures, or neurophysiological variables. GPT models assume finite-mixture distributions, with weights determined by a processing tree structure, and continuous components modeled by parameterized distributions such as Gaussians with separate or shared parameters across states. We discuss identifiability, parameter estimation, model testing, a modeling syntax, and the improved precision of GPT estimates. Finally, a GPT version of the feature comparison model of semantic categorization is applied to computer-mouse trajectories.     

Cross-Domain Development of Scientific Reasoning

The two studies presented here examine processes of theory revision and strategy change that occur when preadolescent subjects engage in self-directed exploration of a problem domain. The microgenetic method, involving frequent encounters with the same tasks over a period of months, permitted detailed observation of the change process. Not only do theories themselves undergo revision but also the reasoning strategies subjects use to generate new knowledge show improvement over time. The cross-domain feature of the research made it possible to establish that these strategies show co-development when subjects are observed over time working in two different content domains. The research thus accomplishes the objective of more clearly distinguishing the reasoning competencies that are developing from the domain-specific contexts in which they are situated.     

因果信息在贝叶斯推理中的作用:问题情境的调节

以大学生为被试,考察因果信息在不同贝叶斯推理问题中的作用。结果表明:(1)问题情境的主效应显著(F(1,122)=16.33,p0.05,η~2=0.120),因果信息的主效应不显著((F(1,122)=1.161,p=0.283,η~2=0.01),但问题类型和因果信息的交互作用显著(F(1,122)=4.757,p0.05,η~2=0.038)。(2)不同类型的问题上因果信息的作用是不同的。具体表现为,在乳癌问题中,增加了因果信息,被试的正确率明显提高(χ~2(1)=6.759,p0.05,V=0.607),而在中彩问题中没有因果信息的推理成绩反而更好(χ~2(1)=1.864,p=0.221,V=0.167)。

分类活动对归纳推理多样性效应的影响

归纳推理多样性效应被证实为普遍存在的,然而研究者Heit和Medin却对多样性效应的普遍性存在分歧。本文通过三个实验针对两位学者的分歧展开研究。结果发现:1.两位学者之间的分歧是由不同的分类活动引起的。当分类活动为外显时,被试的推理结果既不支持Medin,也不支持Heit;当分类活动内隐时,被试的推理结果支持Heit的观点。2.人们在日常生活及现实情境中,往往是根据直觉对事物进行分类及多样性推理。     

The Development of Strategic Processing of Ambiguous Words: Riddles Versus Neutral Context

Children in Grades 4 and 6 read isolated target words following the auditory presentation of an ambiguous word (e.g., deck). The ambiguous word occurred as the last word in either a neutral sentence (e.g., “There is the deck”) or as the last word in a riddle (“Why couldn't anybody play poker on the ark? Because Noah sat on the deck). Related target words were consistent with either the dominant meaning (e.g., porch) or the subordinate meaning (cards) of the ambiguous word. In the neutral context, Grade 4 children showed equivalent facilitation for dominant and subordinate targets relative to unrelated target words; Grade 6 children showed facilitation only for the dominant targets. In the riddle context, both groups of children showed equivalent facilitation for the two types of related targets. The neutral context results supported the hypothesis that the two bases of context effects—automatic lexical access and selective access—develop at different rates (Simpson &; Foster, 1986). The results obtained from the riddles suggest that the selective process is strategic (Ceci, 1989).     

Counterfactual Reasoning for Regretted Situations Involving Controllable Versus Uncontrollable Events: The Modulating Role of Contingent Self-Esteem

We report a study that examined the modulating impact of contingent self-esteem on regret intensity for regretted outcomes associated with controllable versus uncontrollable events. The Contingent Self-Esteem Scale (e.g., Kernis & Goldman, 2006) was used to assess the extent to which a person’s sense of self-worth is based on self and others’ expectations. We found that there was an influence of self-esteem contingency for controllable but not for uncontrollable regret types. For controllable regret types individuals with a high contingent (i.e., unstable) self-esteem reported greater regret intensity than those with a low contingent (i.e., stable) self-esteem. We interpret this finding as reflecting a functional and adaptive role of high contingent self-esteem in terms of mobilizing the application of counterfactual reasoning and planning mechanisms that can enable personal expectations to be achieved in the future.     

"锚定参照错误"偏向对贝叶斯推理成绩的影响

采用贝叶斯推理问题作为实验材料,通过分析被试推理过程中的理由叙述,探讨被试贝叶斯推理所使用的启发式策略,从认知偏向的角度分析该问题的困难原因.结果发现:(1)在贝叶斯推理过程中,对"击中率"命题的"换位表征"错误和锚定"基础比率"信息导致了"锚定参照错误"偏向,从而表现出对贝叶斯推理成绩显著的高估或低估;(2)"锚定参照错误"偏向程度和锚定参照目标受任务情境的影响;(3)解决良构的问题和非良构的问题时,"换位表征"的现象都有可能发生,而且表现得比较一致.
