Graphic designers and an experimental psychologist worked together to improve the design of two map symbols which are frequently confused: the symbols for cuttings and embankments on topographic maps. The problem was analysed in terms of the function of the symbols and their likely cognitive representations. Tests were developed to evaluate alternative designs, including an intervisibility task which requirred users to visualize the landform from the symbols viewed in the context of a map. Tests were given to schoolchildren and to experienced map users in order to compare the standard symbols with five alternative designs. Children's performance was strongly affected by the symbols they used, but experienced users were much less affected. After some refinement of the symbols a further experiment demonstrated the superiority of a number of alternative designs over the existing symbols on a range of test: scores were almost double on the intervisibility task. The paper makes recommendations to cartographers and argues for greater consideration of the inexperienced map user in the design process.  相似文献

Summary A study of movement disorders such as Parkinson's disease and Huntington's disease can provide an indication of the motor functions of the basal ganglia. Basal-ganglia diseases affect voluntary movement and can cause involuntary movement. Deficits are often manifested during the coordination of fine multi-joint movements (e. g., handwriting). The disturbances of motor control (e.g. akinesia, bradykinesia) caused by basal-ganglia disorders are illustrated. Data suggest that the basal ganglia play an important role in the automatic execution of serially ordered complex movements.  相似文献

Recent evidence suggests a larger role for personality determinants of the coping response than has been traditionally held. In the two studies presented here, we examined the influence of personality on the use of social support and other coping strategies in samples of undergraduate students. The first study surveyed a range of coping responses to naturally occurring stressors and found that Extraversion was related to social support seeking, optimism (identified as germane to coping in prior research) was related to problem solving, and both dispositions were negatively related to avoidance. The second study used an experimental approach and multiple personality measures to correct for possible methodological problems in the first. Extraversion again proved to be associated with help seeking; moreover, this relationship accounted for that of another disposition, self-esteem—a construct considered crucial in the literature. The utility of personality variables, particularly Extraversion, in predicting and explaining the choice of a coping strategy is discussed.  相似文献

Student’s ability to read computer text was investigated by comparing reading performance on decoding and phonetics tests of the Woodcock-Johnson (Revised) Tests of Achievement, Forms A and B. Fifty-one students completed one form of the reading tests through the traditional administration method and a second form using computer administration. Initial form and administration order were counterbalanced. Coefficients of equivalence of .91 and .86 were obtained for traditional and computer administration methods of the two tests. The results are interpreted as indicating that computer-administered reading tests can assess the same domains as traditional measures, and that they may become increasingly important in the complete assessment of functional reading skills.  相似文献

Qualitative reviews of the withdrawal literature have reached inconsistent conclusions regarding the strength of the relationship between promotion and turnover. Several issues were addressed in this study which may account for these inconsistencies. First, we differentiate among three distinct operationalizations of promotion: (1) promotion satisfaction; (2) perceptions of promotional opportunity; and (3) actual promotion. We then conduct quantitative reviews using meta-analytic procedures on turnover and the three operationalizations of promotion. We found no significant relationships between promotion satisfaction and turnoveror between perceived promotional opportunities and turnover. However, a significant negative relationship was found between actual promotion and turnover. Theoretical implication of these findings are presented.  相似文献

The relationship between academic gender bias and female students' agentic self-efficacy expectations was examined. Agentic self-efficacy expectations was defined as an individual's beliefs about her ability to successfully engage in proactive educational and career facilitative behaviors. Participants included 67 full-time junior and senior undergraduate women enrolled in traditional, nontraditional, and gender-neutral majors. Results revealed that perceived academic gender bias was significantly predictive of agentic self-efficacy expectations, above and beyond the contributions of sex role attitudes, gender concentration of major, and race/ethnicity. Implications for women's career development and future research are discussed.  相似文献
