The objective of this paper is to discuss whether children have a capacity for deontic reasoning that is irreducible to mentalizing. The results of two experiments point to the existence of such non‐mentalistic understanding and prediction of the behaviour of others. In Study 1, young children (3‐ and 4‐year‐olds) were told different versions of classic false‐belief tasks, some of which were modified by the introduction of a rule or a regularity. When the task (a standard change of location task) included a rule, the performance of 3‐year‐olds, who fail traditional false‐belief tasks, significantly improved. In Study 2, 3‐year‐olds proved to be able to infer a rule from a social situation and to use it in order to predict the behaviour of a character involved in a modified version of the false‐belief task. These studies suggest that rules play a central role in the social cognition of young children and that deontic reasoning might not necessarily involve mind reading. 相似文献

Intracerebral muscimol injection is widely used to inactivate discrete brain structures during behavioral tasks. However, little effort has been made to quantify the extent of muscimol diffusion. The authors report here electrophysiological and autoradiographic results obtained after muscimol injection (1 microg/microl) either into the nucleus basalis magnocellularis (0.1-0.4 microl) or into the thalamic reticular nucleus (RE, 0.05-0.1 microl). In 52 rats, multiunit recordings were collected either in the RE or in the auditory thalamus during the 2 h following muscimol injection. Decreases in neuronal activity were observed up to 3 mm from the injection site; their time of occurrence was a function of the distance between the injection and recording sites. Because these decreases cannot be explained by physiological effects, they likely reflected muscimol diffusion up to the recording sites. Autoradiographic studies involved 25 rats and different experimental conditions. Optical density (OD) measures indicated that after a survival time of 15 min, a 0.05 microl injection produced a labeled area of 5.25 mm(2) at the injection site and a rostrocaudal labeling of 1.7 mm. Increasing the survival time to 60 min, or increasing the injected volume to 0.1 microl, systematically led to a larger labeled area at the injection site (8-12 mm(2)) and to a larger rostrocaudal diffusion (2.0-2.5 mm). Direct quantifications of radioactivity by a high-resolution radioimager validated the OD measures and even indicated a larger muscimol diffusion (up to 3.25 mm). Thus, these data point out that muscimol diffusion after intracerebral microinjection is larger than usually supposed. The relationships between these results and those obtained in behavioral studies are discussed. 相似文献

Couples (22 young, married, 18 young unmarried) completed the Exchange Orientation Scale, which measures how much individuals believe equality of exchange should characterize their social relationships, as well as the Norman Personality Trait Scale, which gives measures for the self and ideal-self. Couples also rated their sexual satisfaction, their partners' physical attractiveness, their own attractiveness, and had their photographs evaluated for attractiveness by disinterested raters. Subgroups were formed of physically attractive couples, couples in which the members were of disparate attractiveness, and couples in which the individuals perceived themselves as equal to their partners in attractiveness or as inferior. In accordance with exchange theory, the hypotheses were (1) unmarried men would show higher exchange scores than married men, (2) attractive men in disparately attractive couples would show greater exchange scores than attractive men in both-attractive couples, (3) attractive members of disparately attractive couples would possess lower self-acceptance and (4) experience greater sexual satisfaction than attractive members of both-attractive couples. Results supported all hypotheses in varying extents. 相似文献

Tribes constitute a research focus for postmodern consumer research and an alternative way of targeting marketing action. Consumers are supposed to value the goods and services which, through their linking value, permit and support social interaction of the communal type, products or services that support AB and not the fact of being A or B. This paper seeks to explore current developments in postmodern consumer research in terms of methods used to identify tribes and in terms of approaches used to elaborate an offer which is capable of supporting tribal rites and to capitalise, at a brand image level, on these tribal phenomena.

In this paper, I argue that moral and institutional evils, even though they are all contingent, are so pervasive and persistent that there is no practical way of responding to them that would lead eventually to the eradication of all of them. Instead, our practical task is to respond to these evils in ways that respect both the basic capabilities and their associated vulnerabilities that are constitutive of each human being. To do this most effectively, one should offer unconditional forgiveness to the perpetrators of evil. The attitude that can best underpin this forgiveness is one of a properly understood indefeasible hope, a hope that always insists that each person is of greater worth than whatever he or she does. 相似文献
