Child-to-parent transmission of cytomegalovirus may be reduced by increasing protective behaviors (handwashing and glove use) and decreasing risky behaviors (intimate contact between child and parent). This study showed that an educational intervention resulted in increases in reported and objective measures of protective behaviors and decreases in reported risky behaviors. Further study must determine if changes in protective and risky behavior are maintained and prevent cytomegalovirus transmission.  相似文献

The stigma associated with obesity is likely to limit the opportunities obese women have to develop social skills. This hypothesis was tested by having obese (n = 15) and nonobese (n = 22) women converse on the telephone with college students who were unaware of the women's weights. Ratings made by judges who listened to the women's contributions to the conversations but who were unaware of their weights showed that obesity was negatively related to judgments about the women's likability, social skills, and physical attractiveness. The telephone partners of obese women rated the women and themselves more negatively than did the partners of nonobese women. Obese and nonobese women generally did not differ in their evaluations of their own and their telephone partners' behavior, and they also did not differ on a measure of social self-esteem. These findings suggest that there are real differences in the social behavior of obese and nonobese women and that these differences affect the impressions formed by those with whom they interact.  相似文献

Suspicion of ulterior motivation and the correspondence bias   总被引:2,自引:0,他引:2  
Three studies examined the hypothesis that when perceivers learn of the existence of multiple, plausibly rival motives for an actor's behavior, they are less likely to fall prey to the correspondence bias than when they learn of the existence of situational factors that may have constrained the actor's behavior. In the first 2 studies, Ss who learned that an actor was instructed to behave as he did drew inferences that corresponded to his behavior. In contrast, Ss who were led to suspect that an actor's behavior may have been motivated by a desire to ingratiate (Study 1), or by a desire to avoid an unwanted job (Study 2), resisted the correspondence bias. The 3rd study demonstrated that these differences were not due to a general unwillingness on the part of suspicious perceivers to make dispositional inferences. The implications that these results have for understanding attribution theory are discussed.  相似文献

The ability of the MacAndrew Alcoholism Scale (MAC) and Scale B of the Millon Clinical Multiaxial Inventory (MCMI) to discriminate independently defined alcoholics with psychiatric diagnoses from other psychiatric patients was examined for males and all alcoholics, using three different criteria of alcoholism. The MAC identified from 80% to 87% of male alcoholics and 76% to 82% of all alcoholics, and from 25% to 52% of male nonalcoholics and 55% to 75% of all nonalcoholics, resulting in a large number of false positives. Scale B identified from 31% to 60% of male alcoholics and 33% to 43% of all alcoholics, and from 73% to 85% of male nonalcoholics and 85% to 94% of all nonalcoholics. The operating characteristics of Scale B showed that it was not as efficient in identifying alcoholics as previous work had indicated. We suggest that Scale B should not be used and the MAC should be used cautiously to discriminate alcoholics with psychiatric disorders from patients without alcoholism.  相似文献

Conformity by an agent to a convention to which the agent is a party is rational only if the agent prefers to conform given the other parties conform and believes the others will conform. But this justification is inadequate; what, for example, is the justification for this belief? The required rational justification requires recourse to (a) preferences for general conformity (as opposed to merely conditional preferences for one's own conformity) and (b) procedures. An agent adopts a procedure when he chooses to perform a whole set of future actions, as opposed to a single action.  相似文献

Clinical pragmatism: a method of moral problem solving   总被引:3,自引:0,他引:3  
This paper presents a method of moral problem solving in clinical practice that is inspired by the philosophy of John Dewey. This method, called "clinical pragmatism," integrates clinical and ethical decision making. Clinical pragmatism focuses on the interpersonal processes of assessment and consensus formation as well as the ethical analysis of relevant moral considerations. The steps in this method are delineated and then illustrated through a detailed case study. The implications of clinical pragmatism for the use of principles in moral problem solving are discussed.  相似文献

present research examined the role of hippocampal NMDA-dependent synaptic potentiation on appetitive instrumental conditioning under a continuous reinforcement schedule. In the first experiment, low (.025 mg.kg) or moderate (.05 mg/kg) dosages of the NMDA receptor antagonist, MK801, failed to increase the number of training days required to reach acquisition criterion; number of training days required to reach criterion for extinction were also unaffected. In the second experiment, a higher dosage (.10 mg/kg) of MK801 or induction of long-term potentiation failed to alter the number of responses occurring during acquisition. These data suggest that hippocampal synaptic potentiation does not play a prominent role in instrumental learning with simple contingency conditions. It is suggested that hippocampal LTP reflects a perceptual process that contributes differentially to spatial cognition, classical and instrumental conditioning.  相似文献

Abstract— Becoming a proficient symbol user is a universal developmental last in the first years of life, but delecting and mentally representing symbolic relations can be quite challenging for young children To test the extent to which symbolic reasoning per se is problematic, we compared the performance of 2-year-olds in symbolic and nonsymbolic versions of a search task. The children had to use their knowledge of the location of a toy hidden in a room to draw an inference about where to find a miniature toy in a scale model of the room (and vice versa) Children in the nonsymbolic condition believed a shrinking machine had caused the room to become the model They were much more successful than children in the symbolic condition, for whom the model served as a symbol of the room The symbol understanding and use.  相似文献

In this study, the correlates of embarrassability, or chronic susceptibility to embarrassment, were examined. Competing theoretical models suggest either that embarrassable people should be especially concerned about others' evaluations of them or that they should lack social skills. Further, shyness and embarrassment are typically considered to be closely related states. To test these propositions, 310 participants provided extensive self-reports of social skill, fear of negative evaluation, self-esteem, self-consciousness, and negative affectivity. Regression and factor analyses indicated that, compared to those of low embarrassability, highly embarrassable people are particularly concerned with the normative appropriateness of behavior and are more motivated to avoid rejection from others. In contrast, shyness was best predicted by low social self-confidence and low social skill. The data best support a social-evaluation model of embarrassment and argue that embarrassability is linked to the appropriateness of social behavior, and shyness to its effectiveness.  相似文献
