采用时间比较法,考察数目及其呈现方式对时间知觉的影响。任务中,首先呈现标准时距,此时变化刺激的数目或呈现方式,然后呈现比较时距,被试的任务是判断比较时距比标准时距长还是短。实验1和实验2分别采用1秒内和1秒以上的时间,结果发现: 1秒内的时间加工中,刺激一个一个连续呈现时,小数引起标准时距的低估,大数导致标准时距的高估,而同时呈现时,刺激的数目对知觉到的时间无影响;数目及其呈现方式影响计时的准确性,而对计时的变异性和敏感性无影响。时间在1秒以上,同时呈现和连续呈现条件下,刺激的数目影响知觉到的时间;计时的  相似文献

This research examined the effects of vocational interest levels and differentiation on annual income. Following the environmental perspective, we investigated whether relationships existed at the occupation level of analysis. Using data from 665 occupations in the U.S. obtained from U.S. Bureau of Labor Statistics and O*Net, we demonstrated that certain vocational interests – namely investigative, enterprising, and realistic interests – were most critical in predicting annual income for occupations. Controlling for interest levels, differentiation not only positively predicted annual income but also moderated each interest's relationship with income. In addition, occupations' education and training requirement partially mediated the effects of interest profiles on income. Our findings reveal the need for a better understanding of how characteristics of an occupation's interest profile may shape the experiences of its workers.  相似文献

Prior research in social psychology indicates that East Asians from collectivistic and interdependent sociocultural systems are more sensitive to contextual information than Westerners, whereas Westerners with individualistic and independent representation have a tendency to process focal and discrete attributes of the environment. Here we have demonstrated that such systematic cultural variations can also be observed in cyberspace, focusing on self‐presentation of photographs on Facebook, the most popular worldwide online social network site. We examined cultural differences in face/frame ratios for Facebook profile photographs in two studies. For Study 1, 200 digital profile face photographs of active Facebook users were randomly selected from native and immigrant Taiwanese and Americans. For Study 2, 312 Facebook profiles of undergraduate students of six public universities in East Asia (Hong Kong, Singapore, and Taiwan) and the United States (California and Texas) were randomly selected. Overall, the two studies clearly showed that East Asian Facebook users are more likely to deemphasize their faces compared to Americans. Specifically, East Asians living in Hong Kong, Singapore, and Taiwan exhibited a predilection for context inclusiveness in their profile photographs, whereas Americans tended to prioritize their focal face at the expense of the background. Moreover, East Asian Facebook users had lower intensity of facial expression than Americans on their photographs. These results demonstrate marked cultural differences in context‐inclusive styles versus object‐focused styles between East Asian and American Facebook users. Our findings extend previous findings from the real world to cyberspace, and provide a novel approach to investigate cognition and behaviors across cultures by using Facebook as a data collection platform.  相似文献

Different dimensions of health are intertwined. The purposes of this study were: (1) to investigate the psychological and socioeconomic health status of community‐dwelling older adults in Taiwan, and (2) to compare the psychological and socioeconomic health differences among people of different age groups, gender, marital status, and exercise habits. Using stratified random sampling, 384 Taiwanese community‐dwelling older adults were recruited for this survey research. Based on the Health Model of Older Adults, seven constructs were measured: (1) psychological health: sleep quality, emotional health, cognitive functioning, and health promotion behaviors; (2) socioeconomic health: social engagement, social support, and financial status. Results showed that most participants were in a good state of psychological and socioeconomic health, except that 38.02% of them suffered from sleep disruptions, and the majority of them were not involved in any social group, nor engaged in any volunteer work. Young‐old older adults had better psychological and socioeconomic health than middle‐old and old‐old older adults. Male older adults had better psychological health than female older adults; however, they had less social engagement and social support than female older adults. Married older adults and exercisers performed better in most of the psychological and socioeconomic health indicators than single/widowed older adults and non‐exercisers.  相似文献

A complete survey of a network in a large population may be prohibitively difficult and costly. So it is important to estimate models for networks using data from various network sampling designs, such as link-tracing designs. We focus here on snowball sampling designs, designs in which the members of an initial sample of network members are asked to nominate their network partners, their network partners are then traced and asked to nominate their network partners, and so on. We assume an exponential random graph model (ERGM) of a particular parametric form and outline a conditional maximum likelihood estimation procedure for obtaining estimates of ERGM parameters. This procedure is intended to complement the likelihood approach developed by  Handcock and Gile (2010) by providing a practical means of estimation when the size of the complete network is unknown and/or the complete network is very large. We report the outcome of a simulation study with a known model designed to assess the impact of initial sample size, population size, and number of sampling waves on properties of the estimates. We conclude with a discussion of the potential applications and further developments of the approach.  相似文献

A serious challenge to Hull’s (1943) theory of reminiscence and intertrial-interval effects is posed by the current contention that reactive inhibition (IR) must be task-specific since it does not seem to transfer from one task to another. This notion was examined within the framework of a practice-rest paradigm in which three control groups were given 20 1-min trials on a principal task with intertrial intervals of 0, 5, and 70 sec, respectively, while two experimental groups practiced alternately on the principal task and a secondary task known to produce evidence for IR. The two secondary tasks varied in their similarities to the principal task. Additional control groups were used to assess the magnitude of habit transfer effects. The total sample consisted of 70 males and 70 females whose modal age was 18 yr. With habit transfer effects controlled, results showed clearly that work effects transferred from the alternate tasks to the main task without regard for differences in similarity. Thus, the task-specificity hypothesis was not supported.  相似文献

This study examined longitudinal associations of prenatal exposures as well as childhood familial experiences with obesity status from ages 10 to 18. Hierarchical generalized linear modeling was applied to examine 5,156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth. Higher maternal weight, maternal smoking during pregnancy, lower maternal education, and lack of infant breastfeeding were contributors to elevated adolescent obesity risk in early adolescence. However, maternal age, high birth weight of child, and maternal annual income exhibited long-lasting impact on obesity risk over time throughout adolescence. Additionally, childhood familial experiences were significantly related to risk of adolescent obesity. Appropriate use of family rules in the home and parental engagement in children’s daily activities lowered adolescent obesity risk, but excessive television viewing heightened adolescent obesity risk. Implementation of consistent family rules and parental engagement may benefit adolescents at risk for obesity.  相似文献
