Variables latentes et propriétés mentales : pour une épistémologie affirmée pragmatiste et réaliste

The reliability of models with latent variables is questioned by different authors: what is the ontology of mental properties? How to integrate the complex of mental processes with latent variables? All these debates raise the question of the legitimacy of latent variables as methodological approach comparatively to new approaches such as Network analysis. By clearly posing the ontological nature of mental properties as emergent properties of mental processes, and by clearly posing a theory of pragmatist and realistic knowledge, our work seeks to show that latent variables are efficient approaches for inferring mental properties.     

Implications of an initial empirical victory for the truth of the theory and additional empirical victories

Psychologists take two propositions for granted. Specifically, empirical verification of predictions derived from a theory (a) support that the theory is more likely to be true and (b) support that additional predictions derived from the theory have an increased probability of being sustained if subjected to empirical testing. In contrast, I argue that both propositions depend strongly on whether auxiliary assumptions are taken into account. When auxiliary assumptions are not taken into account, the first proposition is valid but the second is not. When auxiliary assumptions are taken into account, the first proposition is not valid, and the second proposition encounters additional problems. I use Venn diagrams and Bayesian principles to demonstrate these conclusions.     

有关条件推理中概率效应的实验研究

通过预备实验选取了四种不同条件概率的条件规则和四种不同前后件概率组合的条件规则作为实验材料,以大学生为被试,考察了两种概率因素(条件概率和前后件概率)对条件推理的演绎形式(MP、DA、AC、MT)以及变通形式(四卡问题)的影响。结果表明,两种概率因素对四种条件推理的影响都非常显著,研究进一步证实了人们对四种推理的认可程度主要与范畴前提的概率成正比的结论;但概率因素对四卡问题的解决影响不明显。     

A Sequent Formulation of Conditional Logic Based on Belief Change Operations

Peter Gärdenfors has developed a semantics for conditional logic, based on the operations of expansion and revision applied to states of information. The account amounts to a formalisation of the Ramsey test for conditionals. A conditional A > B is declared accepted in a state of information K if B is accepted in the state of information which is the result of revising K with respect to A. While Gärdenfors's account takes the truth-functional part of the logic as given, the present paper proposes a semantics entirely based on epistemic states and operations on these states. The semantics is accompanied by a syntactic treatment of conditional logic which is formally similar to Gentzen's sequent formulation of natural deduction rules. Three of David Lewis's systems of conditional logic are represented. The formulations are attractive by virtue of their transparency and simplicity.     

Parental conditional regard as a predictor of deficiencies in young children's capacities to respond to sad feelings

This study explored the relationship between parents' use of conditional regard (PCR, Assor, Roth, & Deci, 2004; Roth, 2008) to promote suppression of sad feelings and the following emotional skills in young children: (1) recognition of sadness in facial expressions, (2) awareness of sad feelings in oneself, and (3) empathic response to others' sad feelings. The study distinguished between two PCR components: conditional negative regard (similar to love withdrawal) and conditional positive regard. Emotion‐focused interviews were conducted with 102 children aged 5–6 years, and their parents completed questionnaires assessing parents' use of conditional regard. As expected, both PCR components correlated negatively with the emotional skills. Regression analyses showed that the seemingly benign practice of conditional positive regard had unique negative associations with the three emotional skills also when effects of negative PCR were controlled.

无意识目标启动的定义、机制及应用

无意识目标与社会态度、刻板印象和图式等一样, 是行为的满意状态或结果在个体头脑中的一种表征, 包含有目标设定、追求情境和追求手段等内容。这些内容能够被环境中的刺激自动激活, 在意识不到的情况下影响人的心理和行为。无意识目标启动的概念和其他心理表征的启动不同, 无意识目标启动能够促使带有动机性的行为出现, 启动线索的影响不会随着时间的推移而消失。无意识目标启动的自变量与自身心理状态和环境中他人的影响有关, 无意识目标启动的因变量与任务表现和社会关系的处理有关。“知觉-行为模型”、“无意识行为选择模型”、“评价准备模型”和“情感因素模型”能够分别从“无意识”和“目标”两个角度对无意识目标启动的心理机制进行解释。无意识目标启动原理在商业、教育、医疗等领域当中有着广泛的应用前景, 为了更好地完善理论研究和进行实际应用, 今后应该更加重视无意识目标启动的脑机制研究。     

厌恶与恐惧情绪习得的性别差异研究:一项ERP研究

采用事件相关电位技术（ERPs）,用条件性习得范式探讨厌恶与恐惧情绪习得的性别差异。行为结果表明,在成功习得厌恶、恐惧和中性情绪之后,男女性在唤醒度维度上,性别差异显著;脑电结果表明,在早期N1和P2成分,厌恶情绪与恐惧情绪的习得无显著性别差异;但男女不同性别在N2成分上差异显著,主要表现为女性在厌恶、恐惧、中性这三类CS的N2成分均差异显著,但男性仅厌恶与中性情绪的CS差异显著。结果表明在负性情绪的习得中,女性比男性更敏感。     

Elimination problems in logic: a brief history

A common aim of elimination problems for languages of logic is to express the entire content of a set of formulas of the language, or a certain part of it, in a way that is more elementary or more informative. We want to bring out that as the languages for logic grew in expressive power and, at the same time, our knowledge of their expressive limitations also grew, elimination problems in logic underwent some change. For languages other than that for monadic second-order logic, there remain important open problems.
