The author describes the concept of triadic reality, which he sees as a necessary prerequisite to healthy negotiation of the oedipal phase. Without positive representations of both parents individually-and, significantly, of both parents together in relation to the child-the child is hampered in her efforts to achieve a sense of triadic reality, resulting in difficulties in self representation and in object choice, as well as a limited capacity to love. A detailed case report is presented, highlighting relevant aspects of the author's work with a patient named Marielena.  相似文献

Guided by a transactional model, we examined the predictors and effects of exposure to externalizing peers in a low-risk sample of preschoolers and kindergarteners. On the basis of daily observations of peer interactions, we calculated measures of total exposure to externalizing peers and measures of exposure to same- and other-sex externalizing peers. Analyses of predictors of externalizing peer exposure supported a homophily hypothesis for girls. Tests of peer contagion effects varied by sex, and exposure to externalizing peers predicted multiple problem behaviors for girls but not for boys. Sex differences were a function of childrens own sex, but not of peers sex. The study provides evidence of externalizing peer exposure effects in a low-risk sample of young children, notably for girls.Contributed equally to the conceptualization of this project  相似文献

Parental vaccine hesitancy—delays in vaccine uptake for children—is a significant public health concern. Using an online adult sample of U.S. parents (N = 183), the current research experimentally examined how exposure to cautious or risky social comparison models on social media (in terms of their COVID-19 beliefs and behaviors) influenced parental intentions to vaccinate their children against COVID-19 in the early stages of the pandemic. Additionally, we examined whether the influence of social comparison models was moderated by emotional state (fear or contentment) and parental vaccination status. Overall, we found that parents exposed to cautious (vs. risky) comparison models and vaccinated (vs. unvaccinated) parents reported greater vaccine intentions for their children. We further found that vaccination intentions were highest among unvaccinated parents after exposure to cautious (vs. risky) comparison models, whereas intentions were highest among vaccinated parents after exposure to risky (vs. cautious) comparison models (but only when induced to feel content). Overall, our findings highlight the importance of understanding the additive and interactive impact of psychological and situational factors in shaping parental vaccine hesitancy.  相似文献

Interviewing older adults: validity of self-reports of satisfaction   总被引:1,自引:0,他引:1  
Respondents in a personal interview study were asked to evaluate several domains of their lives using several different response scales that included both verbal and pictorial response alternatives. Structural equation models were specified to permit estimation of the validity of these survey measures. Across all of the items, the concept factors explain an average of about one half of the total variance, method factors explain about one tenth of the variance, and the remaining one third or so of the variance is unique to each item. Comparisons of the validity of reports by respondents of different ages indicate that method factors explain almost twice as much of the variance in the responses of older respondents as in those of younger respondents.  相似文献

This research utilizes the actor-observers paradigm (Jones & Nisbett, 1971) to study driving interactions from the actor, active observer, and passive observer perspectives. Videos of interactions in three driving situations were used to elicit personal and situational causal attributions from subjects. For each interaction, three videos were made, corresponding with each of the three perspectives. Results for two of the interactions were in accordance with the Jones and Nisbett hypothesis, while those of the third were not. Of note was that passive observers gave consistently lower attributional ratings, both personal and situational, compared to actors and active observers. The results are discussed in terms of their relevance to driving behavior and education.  相似文献

GABAA/benzodiazepine receptors in the medial septum modulate the activity of cholinergic neurons that innervate the hippocampus. Injection of benzodiazepine (BDZ) agonists into the medial septum impairs working memory performance and decreases high-affinity choline transport (HAChT) in the hippocampus. In contrast, intraseptal injection of the BDZ antagonist flumazenil increases HAChT and prevents the memory deficits induced by systemic BDZs. The present studies attempted to further characterize the behavioral effects of medial septal injections of flumazenil to an endogenous negative modulator of the GABAA/BDZ receptor complex, diazepam binding inhibitor (DBI). Male Sprague–Dawley rats were cannulated to study the effects of intraseptal injections of these BDZ ligands on spatial working memory, anxiety-related behaviors in the elevated plus maze, and on general locomotor activity. Intraseptal flumazenil (10 nmol/0.5 μl) produced a delay-dependent enhancement of DNMTS performance after an 8-h, but not a 4-h, delay interval. This promnestic dose of flumazenil had no effect on locomotor activity and did not produce changes in measures of anxiety on the plus maze. Intraseptal injection of DBI had no effect (8 nmol/0.5 μl) or slightly impaired (4 nmol/0.5 μl) DNMTS radial maze performance following an 8-h delay, without producing changes in locomotion or plus maze behavior. These data demonstrate that flumazenil has a unique profile of activity in enhancing working memory following intraseptal injection.  相似文献

Thirty women who had prophylactic oophorectomy (PO) and thirty women undergoing ovarian cancer surveillance (OCS) completed a one-time in-depth telephone interview exploring information gathering and decision-making processes. There were close similarities between groups, including age, race, marital status, education, menopausal status, number undergoing genetic testing for BRCA mutations, and number of prophylactic mastectomies. The majority of participants indicated overall satisfaction with their final decision. However, many described the information gathering process as frustrating and anxiety provoking. Participants in both groups expressed a need to process medical information within the context of individual psychosocial needs and personal perceptions and experiences. There were recurrent themes with regard to informational and psychosocial needs and personal perceptions and experiences that impacted decision-making process for these women. The present paper is a companion paper to Swisher et al. (J Repr Med 2001, 46:87–94) with the focus of this paper to illustrate the medical informational processing needs identified by this group of women.  相似文献

ABSTRACT— The "wisdom of crowds" in making judgments about the future or other unknown events is well established. The average quantitative estimate of a group of individuals is consistently more accurate than the typical estimate, and is sometimes even the best estimate. Although individuals' estimates may be riddled with errors, averaging them boosts accuracy because both systematic and random errors tend to cancel out across individuals. We propose exploiting the power of averaging to improve estimates generated by a single person by using an approach we call dialectical bootstrapping . Specifically, it should be possible to reduce a person's error by averaging his or her first estimate with a second one that harks back to somewhat different knowledge. We derive conditions under which dialectical bootstrapping fosters accuracy and provide an empirical demonstration that its benefits go beyond reliability gains. A single mind can thus simulate the wisdom of many.  相似文献
