Recent evidence indicates that certain forms of memory, upon recall, may return to a labile state requiring the synthesis of new proteins in order to preserve or reconsolidate the original memory trace. While the initial consolidation of "instrumental memories" has been shown to require de novo protein synthesis in the nucleus accumbens, it is not known whether memories of this type undergo protein synthesis-dependent reconsolidation. Here we show that low doses of the protein synthesis inhibitor anisomycin (ANI; 5 or 20 mg/kg) administered systemically in rats immediately after recall of a lever-pressing task potently impaired performance on the following daily test sessions. We determined that the nature of this impairment was attributable to conditioned taste aversion (CTA) to the sugar reinforcer used in the task rather than to mnemonic or motoric impairments. However, by substituting a novel flavored reinforcer (chocolate pellets) prior to the administration of doses of ANI (150 or 210 mg/kg) previously shown to cause amnesia, a strong CTA to chocolate was induced sparing any aversion to sugar. Importantly, when sugar was reintroduced on the following session, we found that memory for the task was not significantly affected by ANI. Thus, these data suggest that memory for a well-learned instrumental response does not require protein synthesis-dependent reconsolidation as a means of long-term maintenance.  相似文献

In a sample of low-income families (N = 239), structural equation models assessed predictors of fathers' involvement with preschool-aged children in instrumental, behavioral, and emotional realms. Results suggest that parental conflict has a strong negative relation with father involvement. Fathers' human capital characteristics, healthy psychosocial functioning, and past stability in family relationships all predicted greater father involvement directly and/or indirectly through parental conflict. Numerous differences emerged in the predictive models between resident and nonresident fathers, although few differences were statistically significant. Results suggest that policy efforts aimed at enhancing fathers' responsible parenting should focus both on increasing fathers' human and social capital and on supporting positive family processes.  相似文献

A Esterson (2002) responded to the authors' analysis of recent reformulations of Freud's seduction theory and alleged sexual abuse discoveries. Esterson gave several additional examples of the same type of problematic writing the authors discussed in their original article. His commentary is largely a repetition of several already-published arguments, and his numerous criticisms of the article are, in the authors' opinion, without merit. The authors address confusion over inferring abuse from symptoms, treatment of symptoms versus resolution of cases, and fathers as perpetrators of abuse. It is clear that, as long as the topic of child sexual abuse elicits heated debate, so will Freud's seduction theory, but there may be times when one needs to step back to allow a debate to move forward.  相似文献

This article examines the complex relationship between culture, values, and ethics in mental health care. Cultural competence is a practical, concrete demonstration of the ethical principles of respect for persons, beneficence (doing good), nonmaleficence (not doing harm), and justice (treating people fairly)—the cornerstones of modern ethical codes for the health professions. Five clinical cases are presented to illustrate the range of ethical issues faced by mental health clinicians working in a multicultural environment, including issues of therapeutic boundaries, diagnosis, treatment choice, confidentiality and informed consent, and the just distribution of limited health care resources.  相似文献

While depression is prevalent among immigrant Latinas, mental health literacy is low. Culturally tailored health narratives can improve mental health literacy and are now increasingly featured in Spanish language fotonovelas (i.e., booklets in a comic book format with posed photographs and dialogue bubbles). The purpose of this qualitative study is to explore why a depression literacy fotonovela proved effective with Latina immigrants at risk for depression in a quantitative randomized control study. This study is the qualitative companion of the previously published quantitative piece of a mixed methods study, the latter revealing posttest improvements in depression knowledge, self‐efficacy to identify the need for treatment, and decreased stigma towards mental health care (Hernandez and Organista in Am J Community Psychol 2013 . doi:10.1007/s10464‐013‐9587‐1). Twenty‐five immigrant Latinas participated in structured interviews, in the current qualitative study, 3 weeks after participating in the quantitative study. Results suggest depression literacy improved because participants evidenced high recall of the storyline and characters, which they also found appealing (e.g., liked peer and professional support offered to depressed main character). Further, identification with the main character was reflected in participants recalling similar circumstances impacting their mental health. Despite some improvement, stigma related to depression and its treatment remained for some women. Future research for the improvement of health literacy tools is discussed.  相似文献

The left inferior frontal cortex, the caudate and the anterior cingulate have been proposed as the neural origin of language switching, but most of the studies were conducted in low proficient bilinguals. In the present study, we investigated brain areas involved in language switching in a sample of 19 early, high-proficient Spanish–Catalan bilinguals using a picture naming task that allowed contrasting switch and non-switch trials. Compared to the non-switching condition, language switching elicited greater activation in the head of the left caudate and the pre-SMA/ACC. When the direction of the switching was considered, the left caudate was more associated with forward switching and the pre-SMA/ACC with backward switching. The discussion is focused on the relevance of these brain structures in language control in early, high-proficient bilinguals, and the comparison with previous results in late bilinguals.  相似文献

Stereotype threat impairs performance across many domains. Despite a wealth of research, the long-term consequences of chronic stereotype threat have received little empirical attention. Beyond the immediate impact on performance, the experience of chronic stereotype threat is hypothesized to lead to domain disidentification and eventual domain abandonment. Stereotype threat is 1 explanation why African Americans and Hispanic/Latino(a)s "leak" from each juncture of the academic scientific pipeline in disproportionately greater numbers than their White and Asian counterparts. Using structural equation modeling, we tested the stereotype threat-disidentification hypothesis across 3 academic years with a national longitudinal panel of undergraduate minority science students. Experience of stereotype threat was associated with scientific disidentification, which in turn predicted a significant decline in the intention to pursue a scientific career. Race/ethnicity moderated this effect, whereby the effect was evident for Hispanic/Latino(a) students but not for all African American students. We discuss findings in terms of understanding chronic stereotype threat. (PsycINFO Database Record (c) 2012 APA, all rights reserved).  相似文献

The literature on the development of ethnic identity within the young adult years and during childhood is plentiful. There is less research that examines how this development continues beyond young adult or college years. Research suggests that major life events experienced in adulthood could cause individuals to enter a period of identity reconstruction, yet little is known about this process. Because family and/or familism has been established as an important aspect of Latinos’ identities and lived experiences, this study seeks to examine the dimensions around family dynamics and their potential influences on ethnic identity development processes among adult Latinas. Findings indicate that Latinas often make sense of their ethnic identity when major life events associated with family dynamics occur; such as marriage, childbearing, and negotiating relationships with family members as culture is being transmitted across several generations. These findings have implications for understanding adult education students as well as considering the influence of education on the family dynamics of Latinas.  相似文献

This study examined various functions of social support (i.e., tangible, esteem, belonging, and appraisal) were examined as protective factors for suicidal ideation in a sample of 273 active duty Air Force Security Forces personnel. Generalized linear regression analyses were conducted to determine if various social support functions were differentially associated with the presence and severity of suicidal ideation, both as main effects and as moderators of emotional distress. None of the four social support functions differentiated suicidal from nonsuicidal Airmen, but esteem support (i.e., feeling respected, encouraged, and valued by others) was associated with significantly less severe suicidal ideation (B = ?.074, SE = .025, = .003). A significant interaction of tangible support (i.e., access to material resources) with emotional distress indicated that emotional distress was associated with more severe suicidal ideation only among Airmen reporting low levels of tangible support (B = .006, SE = .003, = .018). When considered concurrently, both tangible and self‐esteem functions of social support are differentially associated with decreased suicidal ideation among Airmen, but belonging (i.e., having someone to do things with) and appraisal (i.e., having someone to talk to about problems) functions were not. Findings suggest that different aspects of social support affect suicidal ideation in different ways.  相似文献

The associations of various forms of sexual and physical assault with a history of suicide attempts and recent suicide ideation were studied in two distinct samples: active duty military and undergraduate students. A total of 273 active duty Air Force personnel and 309 undergraduate students anonymously completed self‐report surveys of assault victimization, emotional distress, belongingness, recent suicide ideation, and previous suicide attempts. Among military personnel, rape, robbery, or violent assault was associated with a nonsignificant trend toward increased risk for suicide attempts, whereas physical abuse or battering as an adult was significantly associated with recent suicide ideation. Among undergraduates, unwanted sexual experiences as an adult and physical or sexual abuse as a child were significantly associated with increased risk for suicide attempt, but only unwanted experiences as an adult was significantly associated with increased risk for suicide ideation. Experiencing multiple forms of assault increased risk for suicide attempts and ideation in both groups. Results suggest that different types of assault contribute differentially to suicide risk in military versus undergraduate populations, but experiencing multiple types of assault is associated with increased risk in both groups.  相似文献
