The authors examined decreases across the early adolescent years in child reports of perceived support from mothers to determine whether the rate of decline differed as a function of the initial amount of perceived negativity in the mother-child relationship. Participants included a diverse sample of 197 girls and 116 boys who were in the 1st year of middle school (6th grade, ages 11 to 13 years) at the beginning of the study. Separate growth curve models revealed associations between the rate of change in child-reported perceived support and the initial level of both child-reported perceived negativity and mother-reported perceived negativity. Over-time declines in child-reported perceived support were larger for adolescents whose initial levels of perceived negativity were greater. The findings are consistent with the claim that mothers and children with the worst relationships at the outset of adolescence experience the greatest deterioration in relations across the early adolescent years.  相似文献

The present research investigated whether certain conceptualizations of time influence the planning fallacy or the tendency to underestimate predicted task durations. In Experiment 1, participants were presented with one of three types of primes (video, linguistic, video + linguistic) that reflected either an ego or time motion perspective (i.e. an individual moving through time vs. time moving toward an individual). Afterwards, all participants predicted the amount of time required to sort and shelve a stack of journals before actually completing the task. The results showed that across all priming conditions, subjects in the ego motion condition underestimated to a greater extent than those in the time motion condition. Experiment 2 replicated this effect and also found that underestimations are reduced when the implied duration of the experimental session is short vs. long. As a set, these findings have relevant theoretical implications and suggest some potential de-biasing techniques.  相似文献

Ankle inversion injuries are common, yet little is known about the error associated with different positions as inversion depth increases. In this study, absolute judgments made without feedback were used to measure discrimination of different extents of ankle inversion which arose from active movements made to physical stops by 20 self-reported right side-dominant participants. Testing was conducted over three sets of five inversion depths that were within a range of 1.4 degrees and centered around mean depths of 8,11, and 14 degrees. Discrimination of ankle inversion movements decreased linearly with depths of movement further into inversion, both within and across the sets of inversion depths. Thus, error in assessing movement position increased with inversion depth. Inversion movements that were made with the left foot were significantly better discriminated at all depths than those made with the right foot.  相似文献

One of the most pervasive gender stereotypes in Western culture concerns expectations regarding men's and women's emotionality. Whereas men are expected to be anger prone, women are expected to smile more. At the same time, men are generally perceived as more facially dominant and facially dominant individuals are expected to show more anger. That is, both facial appearance and social role expectations would lead observers to expect men to show more anger. The present research had the goal to disentangle the unique contribution of these two factors. As it is impossible in our society to fully untangle the influence of these factors since they are highly confounded, we created an alien society where these factors could be unconfounded. In this alien world, Deluvia, child rearing is exclusively assumed by a third gender, the caregiver, whereas men and women share the same social roles. The facial appearance of the Deluvians was varied along the dominance continuum. The results showed that facially dominant Deluvians, regardless of gender, were expected to show more anger, disgust, and contempt and less happiness, fear, sadness, and surprise. Also, the nurturing caregivers were expected to show less anger, contempt, and disgust as well as more fear, sadness, and surprise, regardless of facial appearance. No effect of gender per se on perceived emotionality was found. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

To evaluate the efficacy of cognitive rehabilitation therapies (CRTs) for mild cognitive impairment (MCI). Our review revealed a need for evidence-based treatments for MCI and a lack of a theoretical rehabilitation model to guide the development and evaluation of these interventions. We have thus proposed a theoretical rehabilitation model of MCI that yields key intervention targets–cognitive compromise, functional compromise, neuropsychiatric symptoms, and modifiable risk and protective factors known to be associated with MCI and dementia. Our model additionally defines specific cognitive rehabilitation approaches that may directly or indirectly target key outcomes–restorative cognitive training, compensatory cognitive training, lifestyle interventions, and psychotherapeutic techniques. Fourteen randomized controlled trials met inclusion criteria and were reviewed. Studies markedly varied in terms of intervention approaches and selected outcome measures and were frequently hampered by design limitations. The bulk of the evidence suggested that CRTs can change targeted behaviors in individuals with MCI and that CRTs are associated with improvements in objective cognitive performance, but the pattern of effects on specific cognitive domains was inconsistent across studies. Other important outcomes (i.e., daily functioning, quality of life, neuropsychiatric symptom severity) were infrequently assessed across studies. Few studies evaluated long-term outcomes or the impact of CRTs on conversion rates from MCI to dementia or normal cognition. Overall, results from trials are promising but inconclusive. Additional well-designed and adequately powered trials are warranted and required before CRTs for MCI can be considered evidence-based.  相似文献

The effective provision of psychotherapy services to individuals with intellectual disability requires consideration of ethical issues related to clinical competence, access to services, obligations to multiple parties, guardianship, and appropriate assessment practices. This article provides an overview of major ethical considerations with guidance for clarifying and resolving common ethical concerns. Psychologists are encouraged to expand access to psychotherapy services for this population while maintaining awareness of potential modifications, training needs, and boundaries of professional competence. The authors provide recommendations and resources for effective and ethical treatment of psychotherapy clients with intellectual disabilities.  相似文献

The standard use of the propositional calculus ('P.C.’) in analyzing the validity of inferences involving conditionals leads to fallacies, and the problem is to determine where P.C. may be ‘safely’ used. An alternative analysis of criteria of reasonableness of inferences in terms of conditions of justification rather than truth of statements is proposed. It is argued, under certain restrictions, that P. C. may be safely used, except in inferences whose conclusions are conditionals whose antecedents are incompatible with the premises in the sense that if the antecedent became known, some of the previously asserted premises would have to be withdrawn.  相似文献

Response speed and accuracy of 48 general aviation pilots were determined under condition of anticipatory physical threat stress (APTS). Variables included unpleasantness of the event (electrical shock), proximity of the event, and relationship of Ss’ performance to the occurrence of the event. The data support inclusion of these variables in Wherry’s model of APTS. Ss who believed they could avoid the shock by an adequate performance were able to maintain or improve that performance while the performance of Ss who perceived the shock as inevitable was deteriorating. Two possible modifications of the APTS model were discussed: (1) weighting APTS determiners according to their effectiveness in generating anticipatory stress, (2) recognizing the interaction of the APTS variables with S’s personality structure.  相似文献

This article considers the similarities between the cosmetic surgery and tattoo industries, focusing on how each has transitioned from a disreputable and deviant industry to achieve varying degrees of mainstream acceptance and success. Specifically, each industry is conceptualized as engaging in “dirty work” requiring practitioners to actively reframe and legitimate their respective industry. Using Event Structure Analysis, I model and compare the development of each industry based on linear historical narratives. The resulting models illustrate the importance of events within each narrative along with their relationship to each other. Findings suggest that the creation of industry-wide professional organizations is integral to changing public perception of a given industry. Furthermore, findings show that the more hierarchical structure of the cosmetic surgery industry, as well as its integration into the medical industry, have helped it to thrive in a manner that contrasts sharply with the more disorganized structure of the tattoo industry.  相似文献
