选择性注意的分心物加工机制对工作记忆的影响

通过实验法严格筛选被试,探讨了在有无分心物干扰的条件下,选择性注意的分心物加工机制(分心物抑制机制、分心物习惯化机制)对工作记忆的影响。结果揭示了,分心物抑制机制不仅能影响工作记忆的储存而且还影响工作记忆的加工;而习惯化机制只影响工作记忆的储存,不影响工作记忆的加工。     

The Role of Abstract and Specific Knowledge in the Formation of Product Judgments: An Analogical Learning Perspective

Prior research has assumed that existing knowledge exerts its influence on consumer judgments primarily through abstract knowledge structures. Consequently, little attention has been given to the possibility that judgments may, under certain circumstances, be influenced by knowledge associated with more specific knowledge structures. This article examines the factors responsible for determining the impact of abstract versus specific knowledge on consumer judgments. Based on the Consumer Learning by Analogy model (CLA model; Gregan‐Paxton & John, 1997), it is argued that the relative influence of abstract and specific knowledge is a function of (a) the relation between the new product and existing knowledge and (b) the nature of consumer's knowledge. These ideas were tested in a series of experiments in which participants were required to judge a new product that varied in its relation to an existing product or brand. In this context, the influence of specific knowledge was most evident when participants were able to construct an attribute mapping, but not a relational mapping, to link the novel product to a familiar brand exemplar. When it was possible to construct a relational mapping, a more abstract knowledge structure, such as a schema, was retrieved and used as the basis of product judgments.     

A Test and Refinement of the Demand–Control–Support Model in the Construction Industry

This study aims at a test and further refinement of the Demand–Control–Support (DCS) model among construction workers (N = 210). On the basis of theory and empirical evidence, we hypothesized that mental or physical job demands, low job control, and lack of social support at work have direct and synergistic effects on burnout. The model was expanded by hypothesizing that burnout mediates the relationships between these potentially demanding working conditions on the one hand, and health complaints on the other. Results of a series of structural equation analyses partly supported these hypotheses. The proposed model fitted adequately to the data, although some variables in the DCS model did not make a unique contribution to explaining variance in burnout and (indirectly) health complaints. Interestingly, lack of social support was the most important determinant of burnout and health complaints among construction workers. In addition, a significant three-way interaction effect partly confirmed the synergism hypothesis: Physical demands were only related to burnout if participants had poor job control and reported high social support. The implications of these findings for research and practice are discussed.     

Examining a Gender Stereotype: Menopausal Women1

Two studies evaluated whether there was a subtype of menopausal women and, if so, how it differed from the global gender stereotype. Study 1 had participants generate items associated with women going through menopause, midlife women, and midlife men. Results showed that there is a menopausal women stereotype, and it is mostly negative in content. Moreover, this stereotype differs from the perceptions of women in general. Study 2 examined the effects of the menopausal women stereotype by employing the illusory correlation paradigm (e.g., McConnell, Sherman, & Hamilton, 1994) and found that participants greatly overestimated the number of times that menopausal women and negative moods appeared together. This research highlights the importance of examining stereotype subtypes and subgroups     

Thinking styles,self‐esteem,and extracurricular experiences

This study had two objectives. The first was to examine the relationship between thinking styles and self‐esteem. The second objective was to investigate the relationship of the participants' extracurricular experiences to both thinking styles and self‐esteem. Seven‐hundred and ninety‐four university students from Hong Kong participated in the study. Participants responded to the Thinking Styles Inventory (Sternberg & Wagner, 1992) and the Self‐Esteem Inventory (Adult Form, Coopersmith, 1981) as well as to a questionnaire designed to elicit both personal and situational characteristics. It was found that thinking styles and self‐esteem are statistically related. Meanwhile, both thinking styles and self‐esteem are statistically related to the participants' extracurricular experiences. Implications of these findings for teachers are discussed.
