Carsharing originated in Europe and then expanded to developed countries such as the United States. With the revival and popularity of the “Sharing Economy,” carsharing has remarkably increased in China in recent years. Carsharing has increased convenience for individuals without private cars and is changing the traditional view of car ownership. Chinese college students are a large, highly educated group with low incomes and low rates of car ownership. Understanding the determinants of Chinese college students' intention to carshare is critical to promote carsharing services. In this research, an expanded version of the theory of planned behavior, which contains environmental concern, is the theoretical research framework. The model was empirically tested by using the questionnaire data of 356 college students from four universities in Qingdao, China. The results indicate that subjective norm and the perceived behavioral control are directly and positively associated with Chinese college students’ intention to use carsharing, and attitude and environmental concern have no direct correlation with the intention. Environmental concern has a significant direct effect on attitude, subjective norm, and perceived behavioral control. In addition, environmental concern indirectly impacts Chinese college students’ intention to use carsharing through subjective norm and perceived behavioral control. The findings yield practical insights for carsharing organizations and transportation planners. Based on these results, limitations of this study and suggestions for further research are discussed. 相似文献

The relationship between perfectionism and eating disorders is well established and is of theoretical interest. This study used an experimental design to test the hypothesis that manipulating personal standards, a central feature of perfectionism, would influence eating attitudes and behaviour. Forty-one healthy women were randomly assigned either to a high personal standards condition (n = 18) or to a low personal standards condition for 24 h (n = 23). Measures of personal standards, perfectionism, and eating attitudes and behaviour were taken before and after the experimental manipulation. The manipulation was successful. After the manipulation, participants in the high personal standards condition ate fewer high calorie foods, made more attempts to restrict the overall amount of food eaten, and had significantly more regret after eating than those in the low personal standards condition. Other variables remained unchanged. It is concluded that experimental analyses can be of value in elucidating causal connections between perfectionism and eating attitudes and behaviour. 相似文献

This paper describes the use of a theory of change approach to community-based cross-agency service planning for children with serious emotional disturbance and their families. Public agency planners in Contra Costa County, California used the theory of change approach to organize service planning for a population of youth who had been arrested and involved with juvenile probation. The theory of change process described in this paper links community outcomes with planned activities with the assumptions or principles that underlie the community planning efforts. When complete, a theory of change logic model can serve as a guide for implementation, ensuring that community plans for service delivery remain true to their intent. The theory of change development process includes twelve stages and is based on a step-by-step approach. Theory of change logic models establish a context for articulating a community's shared beliefs and prompt local stakeholders to establish logical connections between the population to be served, expected results, and strategies intended to achieve those results. 相似文献

The ability of four tufted capuchin monkeys (Cebus apella) to recognize the causal connection between seeing and knowing was investigated. The subjects were trained to follow a suggestion
about the location of hidden food provided by a trainer who knew where the food was (the knower) in preference to a trainer
who did not (the guesser). The experimenter baited one of three opaque containers behind a cardboard screen so that the subjects
could not see which of the containers hid the reward. In experiment 1, the knower appeared first in front of the apparatus
and looked into each container; next, the guesser appeared but did not look into any containers. Then the knower touched the
correct cup while the guesser touched one of the three randomly. The capuchin monkeys gradually learned to reach toward the
cup that the knower suggested. In experiment 2, the subjects adapted to a novel variant of the task, in which the guesser
touched but did not look into any of the containers. In experiment 3, the monkeys adapted again when the knower and the guesser
appeared in a random order. These results suggest that capuchin monkeys can learn to recognize the relationship between seeing
and knowing.

Preschoolers’ understanding that an object can be accurately described using two different non-synonymous words was investigated using a task in which children (N = 36) had to judge which of two animals had provided correct adjectival labels for a series of pictures. For some pictures, only one animal provided a correct adjective, for some both animals were correct, and for some neither was correct. For all types of judgement, 4-year-olds outperformed 3-year-olds. Children in both age groups performed worst on trials where both animals were correct. Children's performance on the adjectives task related to concurrent understanding of the appearance–reality distinction, but not to false-belief task performance. Implications for children's mentalizing development are discussed. 相似文献

Barrett, Richert, and Driesenga [Barrett, J. L., Richert, R. A., & Driesenga, A. (2001). God's beliefs versus mother's: The development of nonhuman agents concepts. Child Development, 72(1), 50–65] have suggested that children are able to conceptualize the representational properties held by certain super-natural entities, such as God, before they achieve representational understanding of the human mind. The two experimental conditions of the present study aimed at cross-checking the above suggestion. One hundred and twenty children aged from 3 to 7 years were involved in both conditions. In the first, a modified perspective-taking and appearance-reality task, similar to that adopted in Barrett et al.'s study, was used. The task in the second addressed another aspect of representational understanding of the human mind, that is, the early emerging of the rule that knowledge is constrained by perception. The results of the study showed that younger children systematically treat God as a human protagonist regarding the representational properties they possess. Moreover, it was found that children are able to reason, accurately, about God's representational properties, only upon reaching their 5th year of age, when their representational understanding of the human mind becomes stable and robust. 相似文献

We investigated a test of strategic reasoning (the Windows task) that in different studies has yielded contrasting pictures of young children's executive abilities [Russell, J., Mauthner, N., Sharpe, S., & Tidswell, T. (1991). The “windows task” as a measure of strategic deception in preschoolers and autistic subjects. British Journal of Developmental Psychology, 9, 331–349; Samuels, M. C., Brooks, P. J., & Frye, D. (1996). Strategic game playing through the windows task. British Journal of Developmental Psychology, 14, 159–172]. An experiment with 52 three- to four-year-olds showed robust effects of different wordings for the prompts used to ask children to respond, and found that a single exposure to the facilitating wording led to improved performance on subsequent trials where the standard wording was used. This suggests that the effect of the wording was to help children infer an appropriate basis for responding, and not to reduce the trial-by-trial working memory or inhibitory demands of the task. 相似文献

The author responds to the commentaries of 13 experts on his 1980 American Psychologist article, “Investigation and its discontents: On some constraints on progress in psychological research.” Among the themes addressed are the role of theory in psychological research, the meanings and implications of “productivity” by scholars and researchers, the role of grants, and of money in general, in directing research efforts, and the relation between psychological and neuropsychological research. 相似文献
