When children learn a name for a novel artifact, they tend to extend the name to other artifacts that share the same shape—a phenomenon known as the shape bias. The present studies investigated an intentional account of this bias. In Study 1, 3-year-olds were shown two objects of the same shape, and were given an explanation for why the objects were the same shape even though they were intended to be different kinds. The shape bias disappeared in children provided with this explanation. In Study2, 3-year-olds were shown triads of objects, and were either given no information about the function of a named target object, told the function that object could fulfill, or told the functions all three objects were intended to fulfill. Only in the third condition did children overcome a shape bias in favor of a function bias when extending the name of the target object. These findings indicate that 3-year-olds' shape bias results from intuitions about what artifacts were intended to be. 相似文献

Abstract—With the widespread emergence of required community-service programs comes a new opportunity to examine the effects of requirements on future behavioral intentions. To investigate the consequences of such "mandatory volunteerism" programs, we followed students who were required to volunteer in order to graduate from college. Results demonstrated that stronger perceptions of external control eliminated an otherwise positive relation between prior volunteer experience and future intentions to volunteer. A second study experimentally compared mandates and choices to serve and included a premeasured assessment of whether students felt external control was necessary to get them to volunteer. After being required or choosing to serve, students reported their future intentions. Students who initially felt it unlikely that they would freely volunteer had significantly lower intentions after being required to serve than after being given a choice. Those who initially felt more likely to freely volunteer were relatively unaffected by a mandate to serve as compared with a choice. Theoretical and practical implications for understanding the effects of requirements and constraints on intentions and behavior are discussed. 相似文献

The Motivations to Volunteer: Theoretical and Practical Considerations 总被引:10,自引:0,他引:10
Why do significant numbers of people engage in the unpaid helping activities known as volunteerism? Drawing on functional theorizing about the reasons, purposes, and motivations underlying human behavior, we have identified six personal and social functions potentially served by volunteering. In addition to developing an inventory to assess these motivational functions, our program of research has explored the role of motivation in the processes of volunteerism, especially decisions about becoming a volunteer in the first place and decisions about continuing to volunteer. 相似文献

In three experiments, rats received exposure to a sucrose solution followed by conditioning with a neutral flavor as the conditioned stimulus (CS) and sucrose as the unconditioned stimulus (US). In Experiments 1 and 2, some rats were given both the preexposure and the conditioning phases in a highly familiar context (the homecage), whereas other animals received both phases in a novel and distinctive context. In both cases the magnitude of the conditioning effect was reduced by preexposure to the US. Experiment 3 directly assessed the possible role of contextual cues by changing the context between the exposure phase and the conditioning phase but found no loss of the US-preexposure effect in these conditions. These results lend no support to the blocking-by-context account of the US-preexposure effect; alternative interpretations are considered. 相似文献

The present study investigated the effect of the perception of faces expressing shame on time perception in children aged 5 and 8 years, as well as in adults, as a function of their ability to recognize this emotional expression. The participants' ability to recognize the expression of shame among faces expressing different emotions was tested. They were then asked to perform a temporal bisection task involving both neutral and ashamed faces. The results showed that, from the age of 8 years, the participants who recognized the facial expressions of shame underestimated their presentation time compared to that of neutral faces. In contrast, no time distortion was observed in the children who did not recognize the ashamed faces or in those younger children who did recognize them. The results are discussed in terms of self-conscious emotions which develop to involve an attentional mechanism. 相似文献

Adults and children seem to essentialize certain social categories. Three studies investigated whether, and how, exposure to ethnic diversity affects this bias. Participants were 516 kindergarten, 2nd grade, and 6th grade Israeli Jewish and Arab children attending regular (mono-cultural) or integrated schools. Study 1 revealed that exposure increased the salience of ethnicity, especially for Jewish children. Study 2 showed no differences among groups at kindergarten regarding the relevance of recalling a story character's ethnicity, but by 2nd grade, Jewish children attending integrated schools were the most likely to mention such information. Finally, Study 3 revealed that while all kindergarteners started off at a similar level of essentialism towards ethnicity, exposure affected Arab, but especially Jewish, children's essentialist beliefs. Moreover, there were negative correlations between the salience of and essentialism towards ethnicity. Thus, interethnic exposure alleviated children's essentialist bias towards ethnicity and did so via making children aware of, rather than blind to, ethnic categories. 相似文献

A good sense of humor is sexually attractive, perhaps because it reveals intelligence, creativity, and other ‘good genes’ or ‘good parent’ traits. If so, intelligence should predict humor production ability, which in turn should predict mating success. In this study, 400 university students (200 men and 200 women) completed measures of abstract reasoning (Raven's Advanced Progressive Matrices), verbal intelligence (the vocabulary subtest of the Multidimensional Aptitude Battery), humor production ability (rated funniness of captions written for three cartoons), and mating success (from the Sexual Behaviors and Beliefs Questionnaire). Structural equation models showed that general and verbal intelligence both predict humor production ability, which in turn predicts mating success, such as lifetime number of sexual partners. Also, males showed higher average humor production ability. These results suggest that the human sense of humor evolved at least partly through sexual selection as an intelligence-indicator. 相似文献

Illness perception influences health and illness behaviors. This study was designed to estimate illness perception differences between Russian-speaking and Hebrew-speaking Israeli oncology patients. Changes in illness perception associated with time spent in Israel among Russian-speaking patients were also evaluated. Additionally, we evaluated differences in illness perception of patients exposed to Chernobyl’s consequences. A total of 144 oncology patients (77 Hebrew-speaking, 67 Russian-speaking) completed personal data questionnaires and The illness perception questionnaire revised, translated into Russian for this study. Significantly more Russian-speaking oncology patients perceived their illness as chronic and having negative consequences on life (p < .01). Russian-speaking oncology patients tend to have a more negative perception of cancer compared to Hebrew-speaking patients. Time spent in Israel may create more positive perceptions of cancer among these patients. No illness perception differences were found concerning Chernobyl consequences. 相似文献

Earlier studies have shown that feelings of guilt appear to be involved in the burnout process. However, the exact nature of the relationship between burnout, feelings of guilt, and tobacco and alcohol use is unclear. The purpose of this study was to analyze the role of feelings of guilt in the relationship between burnout and the consumption of tobacco and alcohol. Role conflict, Role clarity, and Feedback were included as predictors of burnout. The sample of this cross‐sectional study consisted of 260 Chilean administration and customer service workers. Hypotheses were tested using a path model. The hypothesized model (i.e., Indolence to guilt to tobacco/alcohol use) showed an adequate data fit, including a mediator role of feelings of guilt in the relationship between burnout and alcohol use. The results of this study recommending taking into consideration the evaluation of feelings of guilt as a symptom of burnout in order to develop a more reliable diagnosis of burnout syndrome and its consequences. 相似文献
