Sex and developmental differences by complexity of functions of occupational aspirations of school children across ten years

The present longitudinal study examined the complexity of workers' functions for 65 children's occupational aspirations during a 10-yr. span beginning when the children were 7 yr. old and in Grade 2. Every two years through the senior year in high school, the children were interviewed, for a total of six interviews. Sex and developmental differences in occupational aspirations were examined with respect to the focus on Data, People, or Things. Girls (n=31) selected occupational aspirations requiring greater complexity in People functions throughout the study. From G;rades 2 to 8 boys chose occupations with greater complexity of Things and girls chose occupations with greater complexity of Data. Developmentally, all children chose increasingly more complex Data occupations from Grades 2 to 12. Occupational aspirations in high school showed a decrease in the complexity of workers' functions involving People and Things. These observations would be expected from social cognitive theory and the 1981 career development theory of Gottfredson.     

停表错觉的机制：注意是否为决定因素

通过两个实验探讨了注意是否影响停表错觉（chronostasis）。实验一要求被试在注视时或眼跳后,估计处于眼跳目标或其附近位置的刺激的持续时间;实验二要求被试在眼跳条件下辨别眼跳目标或其附近位置的刺激,以考查两种位置的注意水平。结果表明,眼跳目标位置的注意水平高于其附近位置,而两种位置均可产生停表错觉,且两者的错觉量近似相等。从而说明注意并不影响停表错觉,停表错觉的机制可能是眼跳目标及其附近刺激的知觉提前。     

Using verbal and blind-walking distance estimates to investigate the two visual systems hypothesis

Verbal estimates of egocentric distance are usually too short at distances greater than several meters, yet blindfolded walking to previously viewed targets can be surprisingly accurate. We present evidence from three experiments for the existence of two visual pathways with differentencodings of perceived egocentric distance. We found that (1) blind-walking estimates of egocentric distance are consistently more accurate than verbal reports; (2) an indoor versus outdoor environment selectively influences verbal reports; and (3) wearing prism lenses, which displace the visual field vertically, selectively influences the blind-walking estimates. We interpret these results in terms of the two visual systems hypothesis.     

Perceptions of teachers' general and informational feedback and intrinsic motivation in physical education: two-year effects

Relative change or stability of perceived positive general feedback and perceived informational feedback and their influence on students' intrinsic motivation in physical education over two years were examined. 302 students, ages 11 to 15 years, responded to the Perception of Teacher's Feedback questionnaire. Two years later, these students filled out the questionnaire again, along with a modified version of the Sport Motivation Scale. Analysis showed that both types of perceived feedback exhibited moderate stability over the two years. Perceived positive general feedback demonstrated a significant direct effect on students' intrinsic motivation measured concurrently in physical education. Further, fixing to zero the effect of perceived positive general feedback on intrinsic motivation measured concurrently, an effect emerged over the two years.     

Health beliefs,optimism, and health‐related decisions: A study with Hong Kong Chinese

T he Health Belief Model (HBM; Rosenstock, 1966) is the most widely used psychological theory of health‐related behaviours but its applicability to non‐Western, especially Asian, populations has not been systematically studied. The main objective of the current study was to examine the effects of components of the HBM and dispositional optimism on preventive intention in two separate samples of 220 Hong Kong Chinese adults and 340 Hong Kong Chinese adolescents. Two HBM variables, benefits and barriers, were experimentally manipulated for an imaginary flu outbreak and a hypothetical vaccine. Optimism in the two samples was assessed using the Chinese revised Life Orientation Test (Lai et al., 1998). Participants indicated their intention to take the hypothetical vaccine after reading information for each of the treatment combinations defined by the two HBM variables. The order of the presentation of each of the six treatment conditions was counterbalanced. Results of ANOVA showed that the effects of the two HBM variables were similar in the two groups. Higher benefits and lower barriers were associated with stronger behavioural intention to take the vaccine. The two HBM variables interacted significantly in the adolescent but not the adult sample. Among the adolescents, the difference in intention scores between low and high barriers became larger when the benefits of taking the vaccine increased. In addition, optimism had significant effect on preventive intention only among the adolescents. These findings suggest that age may be an important factor moderating the effects of HBM components as well as optimism on preventive intention in Hong Kong Chinese. Implications of these findings to future research among Chinese were discussed.     

刻板印象威胁来源对防御反应的影响

以多重威胁框架为理论基础,探讨了刻板印象威胁来源对防御反应的影响。实验一和实验二选取了性别-数学刻板印象威胁,分别考察了自我概念威胁和群体概念威胁对女性防御反应的影响。结果发现,不管是自我概念威胁还是群体概念威胁,女性尝试数学题目数量都显著小于语文题目数量,表明产生了领域回避。两项研究共同说明,以自我为刻板印象威胁来源对防御反应产生影响。
