Internal attribution for bad events, along with stable and global attributions, has been regarded as a component of pessimism, a precursor of negative work outcomes. Most evidence in support of this conceptualisation has come from research conducted in individualist cultures. We questioned if internal attribution has the same pessimistic implication in a collectivist culture. Findings from two studies conducted on Chinese employees supported our expectations that the stability and globality dimensions (but not the internality dimension) would predict disengagement responses (such as quitting and being neglectful at work) and lack of engagement responses (such as voicing suggestions and being loyal to the organisation). A reconceptualisation of pessimism in the workplace is therefore necessary. A dimensional, rather than a composite, scoring method is proposed for maintaining the predictive and construct validities of attributional style as an indicator of pessimism.  相似文献

Cognitive neuropsychology provides a theoretical framework and methods that can be of value in the study of developmental disorders, but the "dissociation" logic at the centre of this approach is not well suited to the developmental context. This is illustrated with examples from specific language impairment. Within the developing language system there is ample evidence for interaction between levels of representation, with modularity emerging in the course of development. This means that one typically is seeking to explain a complex pattern of associated impairments, rather than highly selective deficits. For instance, a selective impairment in auditory processing can have repercussions through the language system and may lead to distinctive syntactic deficits that are seen in written as well as spoken language. Changes in the nature of representations and in the relationships between components of a developing system mean that cross-sectional data at a single point in development may be misleading indicators of the primary deficit. Furthermore, traditional cognitive neuropsychology places a disproportionate emphasis on representational (competence) deficits, with processing (performance) deficits being relatively neglected. Methods for distinguishing these two kinds of impairment are discussed, as well as other approaches for elucidating the underlying nature of developmental disorders.  相似文献

We investigated eye‐movements during preschool children's pictorial recall of seen objects. Thirteen 3‐ to 4‐year‐old children completed a perceptual encoding and a pictorial recall task. First, they were exposed to 16 pictorial objects, which were positioned in one of four distinct areas on the computer screen. Subsequently, they had to recall these pictorial objects from memory in order to respond to specific questions about visual details. We found that children spent more time fixating the areas in which the pictorial objects were previously displayed. We conclude that as early as age 3–4 years old, children show specific eye‐movements when they recall pictorial contents of previously seen objects.  相似文献
