大学生决策的内隐偏向研究

分别运用外显的描述性范式和内隐联结测验两种方法对决策的比率偏好及其特性进行了考察,结果表明:(1)外显决策受到效价类型的影响,负效价情景下的比率偏好现象明显降低;(2)被试存在内隐比率偏好效应,这种偏好影响着被试对决策的认知和解释,具有一定的稳定性;(3)运用内隐联结测验来测量内隐比率偏好是有效、敏感的。(4)外显比率偏好与内隐比率偏好涉及决策的不同结构。     

Coordinated affect with mothers and strangers: A longitudinal analysis of joint engagement between 5 and 9 months of age

The coordination of affect in joint attention was assessed in a longitudinal study of 5- to 9-month-old infants as they interacted with mothers and strangers. Results showed that the coordination of affect with joint attention looks increased reliably with age. In addition, context effects were found such that joint attention looks increased while interacting with strangers but not with mothers. The study demonstrates the emergence of joint engagement before the end of the first year, and suggests that affect may play a key role in aspects of joint attention that may be unique to humans.     

BRIEF REPORT Forgetting “murder” is not harder than forgetting “circle”: Listwise-directed forgetting of emotional words

The list-method directed forgetting (DF) paradigm has attracted the attention of clinical psychologists because it is widely believed that a retrieval inhibition mechanism underlies its effects. Thus, the idea is that people are capable of intentionally forgetting negative emotional material. On the other hand, there are reasons to believe that negative stimuli are relatively resistant to forgetting. The present experiment compared listwise DF of emotional and neutral words in healthy college students. A modified procedure (i.e., a simulated computer crash) showed a reliable DF-effect in that list 1 recall was larger under remember than forget instructions whereas the reverse was true for list 2 recall. Emotionality did not modulate the magnitude of this effect. Thus, negative emotional material is not resistant to forgetting. Although overall, the present findings are in line with a retrieval inhibition interpretation (i.e., decreased access to list 1 material), attentional focusing during list 2 learning may provide a sufficient explanation.
