跨领域项目间联结记忆中项目提取和关系提取的分离：一项事件相关电位研究

使用ERPs技术, 探讨跨领域项目间联结记忆中项目提取和关系提取的差异。学习阶段, 系列呈现面孔-事件动词材料, 让被试识记面孔、事件动词以及两者之间的关系; 测验阶段, 要求被试对成对刺激进行“相同”、“重组”或“新”判断。结果发现：提取阶段, 刺激呈现后约200 ms, “相同”、“重组”和“新”3种条件下的ERPs开始出现分离, 存在“相同/新”、“重组/新”和“相同/重组”三类新旧效应。在200~300 ms, “相同/新”和“重组/新”两类新旧效应表现在前额和额区皮层; 在300~500 ms, 这两类新旧效应广泛地分布在从前到后各个脑区皮层; 在500~700 ms, “相同/新”新旧效应出现在额-顶区皮层, 而无“重组/新”新旧效应; 在700~1400 ms, 这两类新旧效应发生在前额和额区皮层; 在上述4个时段, “相同/重组”关系新旧效应都发生在额中-中央-顶区皮层。从这些结果可以推知：跨领域项目间联结再认中, 项目新旧效应和关系新旧效应同时出现, 但是关系提取比项目提取较晚完成; 额中-中央-顶区皮层关系新旧效应反映了对项目间关系的回忆加工; 而700 ms以后, 前额、额区皮层新旧效应可能反映了项目之间关系提取过程的执行加工功能。     

小学生同伴接纳对其人格发展的影响：友谊质量的多层级中介效应

以班级为单位选取1-6年级23个班级的小学生,通过最好朋友提名法,得到有互选朋友有效被试700人,采用同伴提名法、小学生友谊质量问卷、小学生人格发展教师评定问卷,运用多层线性模型（HLM）考察个体和班级两个水平上的同伴接纳、友谊质量对人格的影响,并在两个水平上检验友谊质量在同伴接纳对人格的影响上的多层中介效应。结果表明：（1）班级水平：班级平均友谊质量对外倾性、亲社会性、认真自控、情绪稳定性有预测作用;班级平均同伴接纳对情绪稳定性有预测作用。（2）个体水平：同伴接纳对人格5个维度均有直接影响;除情绪稳定性,友谊质量分别在同伴接纳对智能特征、外倾性、亲社会性、认真自控影响上有部分中介效应。     

健康行动过程取向模型的发展与前景

健康行动过程取向(HAPA)模型的提出源于健康行为社会认知模型的发展和Bandura社会认知理论的应用。在HAPA中, 健康行为变化被视为一个包括行为产生、保持和恢复在内的连续过程; 结果预期、危险感知、三种自我效能感和两类计划被用来解释意图的形成及其向行动的转化; 两个阶段的划分有助于区分三类干预对象, 建议实施菜单式干预。HAPA模型具有明显的理论优势, 也引发了有关模型实质的争论。当前和未来的研究旨在考察更多的自我调节变量、检验因果模型, 在健康行为的多个领域开展应用和干预研究。     

Resemblance and investment in children

According to evolutionary explanations men hardly ever are absolutely certain about their biological fatherhood therefore they must seek various sources of information to subjectively establish whether they are the genetic fathers of the children they raise. Apicella and Marlowe (2004) showed that fathers who perceived greater similarity between their children and themselves were willing to invest more resources (e.g., time, money, care) in their offspring presumably because the perceived resemblance indicated to the fathers their genetic relatedness with their children. The present study extended the design of Apicella and Marlowe's original study and included both fathers and mothers as participants. Parents were recruited by a female confederate at the airport and at the railway station in Wroclaw (Poland). Multiple regression analyses showed that perceived resemblance predicted parental investment in the child for both men and women. The fact that mothers' declarations of investment in their children also depended on the perceived resemblance factor is not consistent with evolutionary formulations delineated by Apicella and Marlowe (2004; 2007). Future studies must resolve the issue of whether the resemblance‐investment relation in fathers results from men relaying on child's resemblance to themselves as an indicator of their own biological paternity, or whether it results from the more parsimonious phenomenon that people in general are attracted more to other people who are similar to them.     

不同建议来源和关系亲疏下突发事件决策中的框架效应

从建议来源和关系亲疏两个方面对突发事件下的决策框架效应进行探讨。采用2（建议来源：来自普通群众／消防人员）×2（关系亲疏：关系亲密／关系疏远）×2（任务框架：正面框架／负面框架）完全被试间实验设计。实验材料以突发事件为背景,根据Kahneman（1981）研究的经典“亚洲疾病问题”改编。采用集体施测的方法,240名来自济南和重庆的大学生参加了实验。结果发现：①建议来源影响被试的决策反应,尤其是当建议来自专业人士（如消防人员）时,决策者表现出偏好于风险的单向框架效应;②关系亲疏导致不同的框架效应,在拯救包括亲属在内的受灾人群（关系亲密）时,框架效应非常明显;但当拯救陌生人（关系疏远）时,决策者表现出偏好于风险的单向框架效应;③当建议来源和关系亲疏共同作用于被试决策时,凡涉及关系亲密条件时决策者不管建议来源都表现出明显的框架效应;而当关系疏远时不同的建议来源导致决策者的决策框架不同。这说明,不同的建议来源和关系亲疏对突发事件下的决策框架效应产生了影响。     

Extending the classical view of representation

Representation has always been a central part of models in cognitive science, but this idea has come under attack. Researchers advocating the alternative approaches of perceptual symbol systems, situated action, embodied cognition, and dynamical systems have argued against central assumptions of the classical representational approach to mind. We review the core assumptions of the representational view and these four suggested alternatives. We argue that representation should remain a core part of cognitive science, but that the insights from these alternative approaches must be incorporated into models of cognitive processing.

Argumentation: The Mixed Game

The paper introduces a new model of argumentation, the Mixed Game Model, that no longer separates rule-governed competence from actual performance but starts from human beings and their ability of competence-in-performance. Human beings are able to orientate themselves in ever-changing surroundings and to negotiate diverging views in argumentative action games. Argumentation is thus described as a mixed game played by human beings according to principles of probability. These principles include constitutive, regulative and executive principles. Constitutive Principles focus on the basic components of the game, that is, action, dialogue, and coherence as the interplay of different communicative means. Regulative Principles mediate between correlated human abilities and interests. Executive Principles guide the sequencing of action according to cognitive strategies. The mixed game no longer rests on pre-established harmony but describes performance as a non-equilibrial process of negotiation that mediates between order and disorder and is based on the integration of various parameters such as rationality, reason, persuasion and emotion. How the model works is exemplified by an analysis of part of a debate in the European Parliament.     

The Action-Sentence Compatibility Effect: It's All in the Timing

When participants are asked to make sensibility judgments on sentences that describe action toward the body (i.e., "Mark dealt the cards to you") or away from the body (i.e., "You dealt the cards to Mark"), they are faster to respond when the response requires an arm movement in the same direction as the action described by the sentence. This congruence effect is known as the Action–Sentence Compatibility Effect (ACE). This study reports 4 experiments that extend our understanding of the ACE by exploring how the time at which one prepares the motor response required for the sensibility judgment affects the magnitude of the ACE. Results show that the ACE arises only when participants have the opportunity to plan their motor response while they are processing the sentence.     

The Isolation, Primacy, and Recency Effects Predicted by an Adaptive LTD/LTP Threshold in Postsynaptic Cells

An item that stands out (is isolated) from its context is better remembered than an item consistent with the context. This isolation effect cannot be accounted for by increased attention, because it occurs when the isolated item is presented as the first item, or by impoverished memory of nonisolated items, because the isolated item is better remembered than a control list consisting of equally different items. The isolation effect is seldom experimentally or theoretically related to the primacy or the recency effects—that is, the improved performance on the first few and last items, respectively, on the serial position curve. The primacy effect cannot easily be accounted for by rehearsal in short-term memory because it occurs when rehearsal is eliminated. This article suggests that the primacy, the recency, and the isolation effects can be accounted for by experience-dependent synaptic plasticity in neural cells. Neurological empirical data suggest that the threshold that determines whether cells will show long-term potentiation (LTP) or long-term depression (LTD) varies as a function of recent postsynaptic activity and that synaptic plasticity is bounded. By implementing an adaptive LTP-LTD threshold in an artificial neural network, the various aspects of the isolation, the primacy, and the recency effects are accounted for, whereas none of these phenomena are accounted for if the threshold is constant. This theory suggests a possible link between the cognitive and the neurological levels.
