The results of a functional analysis showed that inappropriate sexual behaviors exhibited by a 9-year-old boy who had been diagnosed with traumatic brain injury were maintained by positive reinforcement in the form of social attention. An intervention consisting of functional communication training and extinction resulted in reduced levels of inappropriate sexual behaviors. 相似文献

Social support, stress, and depressive symptoms among the elderly: test of a process model. 总被引:6,自引:0,他引:6
Effects of social support, negative life events, and daily hassles on depressive symptoms were assessed in 301 adults aged 65 or older, in person 3 times at 6-month intervals and by mail questionnaires every month over a 12-month period. Initial social support predicted severity of depressive symptoms 12 months later. Social support and initial levels of depressive symptomatology predicted number of daily hassles but not number of major life events. Effects of social support, depression, and major life events on the incidence of daily hassles remained significant without the inclusion of hassles reflecting depressive symptomatology or problems in relationships or whose content overlapped with major life events. Daily hassles mediated the effects of major life events on subsequent depression. Results did not differ for men and women. Implications for models of the relations among social support, stress, and depression are discussed. 相似文献

Numerous previous investigators have explained species differences in spatial memory performance in terms of differences
in foraging ecology. In three experiments we attempted to extend these findings by examining the extent to which the spatial
memory performance of echidnas (or "spiny anteaters") can be understood in terms of the spatio-temporal distribution of their
prey (ants and termites). This is a species and a foraging situation that have not been examined in this way before. Echidnas
were better able to learn to avoid a previously rewarding location (to "win-shift") than to learn to return to a previously
rewarding location (to "win-stay"), at short retention intervals, but were unable to learn either of these strategies at retention
intervals of 90 min. The short retention interval results support the ecological hypothesis, but the long retention interval
results do not.

This study presents a patient (JH) suffering from acquired deep dyslexia. According to a cognitive model of reading, JH exhibited a significant impairment in both the phonological and lexical routes to reading. A rehabilitation program was proposed. We decided to focus on the lexical route using a priming paradigm. The written words were associated with a picture and the patient was invited to construct a mental association between the written word and the image. During five sessions, JH was trained to read 50 words. A pre-test, a post-test, and an 8-month follow-up session consisted of reading 140 written words including the 50 trained words. At the post-test, 90% of the trained words were accurately read. At the follow-up session, JH's reading performance for the trained words was still highly accurate at 84%. This strong effect is discussed and ways of increasing the patient's abilities to read are proposed. 相似文献

Some recent findings suggest that different implicit measures of prejudice assess the same underlying construct, but other work suggests that they may not. In this experiment, White participants completed a version of a priming measure of racial attitudes that either encouraged categorization of the face primes in terms of race or did not encourage such categorization, and then completed the Implicit Association Test. Correspondence between the two measures was found only when categorization by race was required on the priming measure. Moreover, participants appeared more prejudiced when they were led to construe individuals in terms of race than when they were not so encouraged. The discussion focuses on the potential for dissociations between evaluations of a category and evaluations of members of the category. 相似文献

Safety behavior is involved in the maintenance of anxiety disorders, presumably because it prevents the violation of negative expectancies. Recent research showed that safety behavior is resistant to fear extinction. This fear conditioning study investigated whether safety behavior after fear extinction triggers a return of fear in healthy participants. Participants learned that two stimuli (A and C) were followed by an aversive loud noise (“threat”), and one stimulus (B) was not. Participants then learned to use safety behavior that prevented the loud noise. Next, A and C were no longer followed by the loud noise, which typically led to extinction of threat expectancy. Safety behavior then became available again for C, but not for A and B. All participants used safety behavior on these C trials. In a final test phase, A, B, and C were presented once without the availability to use safety behavior. At each stimulus presentation, participants rated threat expectancy by indicating to what extent they expected that the loud noise would follow. Compared with the last extinction trial, threat expectancy increased for C in the test phase, whereas it did not increase for A and B. Hence, safety behavior after the extinction of classically conditioned fear caused a partial return of fear. The findings suggest that safety behavior may be involved in relapse after exposure-based therapy for anxiety disorders. 相似文献

Stigma appears to influence emotional distress and well-being in cancer survivors, but cross-cultural differences have been ignored. Previous studies suggest that stigma may be especially relevant for survivors of Asian origin. However, their study designs (e.g. focused on female cancers, qualitative designs, and an absence of comparison groups) limit the strength of this conclusion. We hypothesized that (1) Asian-born Chinese immigrants (AI) would report more perceived cancer-related stigma than Western-born Caucasians (WBC); and (2) the impact of stigma on emotional distress and well-being would be greater in AI as compared to WBC. Head and neck cancer survivors (n = 118 AI and n = 404 WBC) completed measures of well-being, emotional distress, and a three-item indicator of stigma in structured interviews. The majority of respondents (59%) reported one or more indicators of stigma. Stigma correlated significantly with emotional distress (r = .13, p = .004) and well-being (r = ?.09, p = .032). Contrary to our hypotheses, WBCs and AIs did not differ in reported stigma nor did we detect differences in its psychosocial impact. Stigma exerts a deleterious psychosocial impact on head and neck cancer survivors. It did not differ significantly between AI and WBC survivors. 相似文献

A fundamental criterion of judgment is consistency among beliefs. To augment traditional methods for studying cognitive consistency, we treat it as a goal and present a priming method for increasing its activation. Three studies use three criteria to validate the method: an increase in the biased evaluation of incoming information, speed in a lexical decision task, and participants' direct reports of greater goal activation. The method is then used to verify the role of the consistency goal in three diverse judgment phenomena. Priming cognitive consistency increases the search for postdecisional supporting information (selective exposure to information), the agreement between preference and prediction (the desirability bias or wishful thinking), and the adjustment of a socially unacceptable implicit attitude to conform to the corresponding explicit attitude. One conclusion is that the cause of these phenomena is not only motivated reasoning (driven directionally by a desired outcome) but also the purely cognitive and nondirectional process of simply making beliefs more consistent.

Gender Role Attitudes across the Transition to Adolescent Motherhood in Mexican‐Origin Families 下载免费PDF全文

Using longitudinal data collected at four time points from 191 dyads of Mexican‐origin adolescent first‐time mothers and their mother figures, we examined changes in and socialization of traditional gender role attitudes across the transition to parenthood using latent growth curve modeling and actor – partner interdependence modeling. Longitudinal growth models indicated that, regardless of nativity status, adolescent mothers' and their foreign‐born mother figures' gender role attitudes became more egalitarian across adolescents' transition to parenthood, spanning from the 3rd trimester of pregnancy to 36 months postpartum. Furthermore, actor‐partner interdependence modeling suggested that adolescents' and their mother figures' gender role attitudes during adolescents' third trimester of pregnancy equally contributed to subsequent increases in one another's gender role attitudes at 10 months postpartum. Importantly, this reciprocal socialization process was not moderated by adolescent mothers' nor by their mother figures' nativity status. Findings suggest that it is important to understand the cultural and intergenerational family processes that contribute to the development of gender role attitudes during the transition to parenthood for adolescent mothers and their mother figures in Mexican‐origin families. 相似文献
