情绪的确定性评价对信息加工的影响

检验了情绪的效价和确定性评价对个体的信息加工策略选择的影响及其心理机制。结果表明,情绪效价对个体的信息加工方式的影响会受到情绪确定性评价的调节。高确定评价的情绪中,积极情绪的被试更倾向于采用启发式加工,消极情绪的被试更倾向于采用系统式加工。积极情绪中,高确定评价情绪的被试更倾向于采用启发式加工,低确定评价情绪的被试更倾向于采用系统式加工。当个体对自己产生情绪的原因进行合理归因后,情绪效价和确定性评价对个体信息加工方式的影响效应都消失了,说明情绪的效价和确定性评价均以信息的方式对对个体信息加工策略的选择产生影响。     

儿童对他人情绪与过去经验的关系的认知

用设置故事情景的方法对儿童对他人情绪与过去经验的关系的认知进行了实验研究。研究表明,4～7岁儿童能够认知他人情绪与过去经验的关系,认知能力随年龄的增长不断提高。情绪效价和情绪情景的匹配性影响儿童对他人情绪与过去经验关系的认知。4、5岁儿童更能认识到正性情绪情景条件下体验到负性情绪的他人情绪与过去经验的关系,其得分显著高于其它情绪情景故事和行为故事。     

Thinking about product attributes: Investigating the role of unconscious valence processing in attribute framing

In the present investigation we conducted three studies to examine how unconscious valence processing influences participants' quality judgments in an attribute-framing task. In Studies 1 and 2 we observed how individuals who had depleted cognitive resources, through distraction (Study 2) and time constraint (Study 3), differed in their responses to an attribute-framing task. In Study 3 we subliminally primed participants with attribute frames and then presented them with a frameless decision task. Our results revealed that attribute framing arises from unconscious valence processing and conscious processing may only play a role when the frame is especially salient.     

The influence of negligence, intention, and outcome on children’s moral judgments

Piaget (1932) and subsequent researchers have reported that young children’s moral judgments are based more on the outcomes of actions than on the agents’ intentions. The current study investigated whether negligence might also influence these judgments and explain children’s apparent focus on outcome. Children (3–8 years of age) and adults (N = 139) rated accidental actions in which the valences of intention, negligence, and outcome were varied systematically. Participants of all ages were influenced primarily by intention, and well-intentioned actions were also evaluated according to negligence and outcome. Only two young children based their judgments solely on outcome. It is suggested that previous studies have underestimated children’s use of intention because outcome and negligence have been confounded. Negative consequences are considered to be important because children assume that they are caused by negligence. The findings indicate that young children can show sophisticated understanding of the roles of intention and negligence in moral judgments.     

Myopic regret avoidance: Feedback avoidance and learning in repeated decision making

Decision makers can become trapped by myopic regret avoidance in which rejecting feedback to avoid short-term outcome regret (regret associated with counterfactual outcome comparisons) leads to reduced learning and greater long-term regret over continuing poor decisions. In a series of laboratory experiments involving repeated choices among uncertain monetary prospects, participants primed with outcome regret tended to decline feedback, learned the task slowly or not at all, and performed poorly. This pattern was reversed when decision makers were primed with self-blame regret (regret over an unjustified decision). Further, in a final experiment in which task learning was unnecessary, feedback was more often rejected in the self-blame regret condition than in the outcome regret condition. We discuss the findings in terms of a distinction between two regret components, one associated with outcome evaluation, the other with the justifiability of the decision process used in making the choice.     

How do valence and meaning interact? The contribution of semantic control

The hub-and-spoke model of semantic cognition proposes that conceptual representations in a heteromodal ‘hub’ interact with and emerge from modality-specific features or ‘spokes’, including valence (whether a concept is positive or negative), along with visual and auditory features. As a result, valence congruency might facilitate our ability to link words conceptually. Semantic relatedness may similarly affect explicit judgements about valence. Moreover, conflict between meaning and valence may recruit semantic control processes. Here we tested these predictions using two-alternative forced-choice tasks, in which participants matched a probe word to one of two possible target words, based on either global meaning or valence. Experiment 1 examined timed responses in healthy young adults, while Experiment 2 examined decision accuracy in semantic aphasia patients with impaired controlled semantic retrieval following left hemisphere stroke. Across both experiments, semantically related targets facilitated valence matching, while related distractors impaired performance. Valence congruency was also found to facilitate semantic decision-making. People with semantic aphasia showed impaired valence matching and had particular difficulty when semantically related distractors were presented, suggesting that the selective retrieval of valence information relies on semantic control processes. Taken together, the results are consistent with the hypothesis that automatic access to the global meaning of written words affects the processing of valence, and that the valence of words is also retrieved even when this feature is task-irrelevant, affecting the efficiency of global semantic judgements.     

情绪的自动加工与控制加工

由于人类注意资源有限,对相关刺激的加工经常以抑制对其它刺激的加工为代价。大量的研究表明,情绪的加工是注意加工过程的一个特例。通常认为情绪信息的加工是自动的,不需要注意资源的调节。但最近的研究结果倾向于支持对立的观点,即情绪信息的加工需要注意的控制。该文结合认知神经科学研究证据,对情绪的自动加工的观点提出质疑。主要的证据来自对情绪的皮层和皮层下通路的研究以及对盲视病人的研究。     

时间间隔和情绪效价对双字词重复启动效应的影响

已有研究大多以中性刺激为材料,尚缺乏同时关注预存知识表征和情绪效价对重复启动效应影响及时间间隔对情绪材料相应效应调节机制的探究。本研究以国际情绪词库翻译而成的汉语双字词为材料并控制其效价,旨在探讨时间间隔对不同情绪效价词的重复启动效应的影响,并与转置词的结果相比较。结果显示,转置词较标准词的重复启动效应更强;立即重复较长间隔条件的重复启动效应更强;情绪效价与时间间隔交互影响词的重复启动效应。上述结果表明,情绪效价对重复启动效应的影响受时间间隔调节且支持注意资源缩减理论;该作用为材料是否具有预存知识表征所调节,支持自下而上加工的观点。
