Selective Attention in Animal Discrimination Learning

The traditional approach to the study of selective attention in animal discrimination learning has been to ask if animals are capable of the central selective processing of stimuli, such that certain aspects of the discriminative stimuli are partially or wholly ignored while their relationships to each other, or other relevant stimuli, are processed. A notable characteristic of this research has been that procedures involve the acquisition of discriminations, and the issue of concern is whether learning is selectively determined by the stimulus dimension defined by the discriminative stimuli. Although there is support for this kind of selective attention, in many cases, simpler nonattentional accounts are sufficient to explain the results. An alternative approach involves procedures more similar to those used in human information-processing research. When selective attention is studied in humans, it generally involves the steady state performance of tasks for which there is limited time allowed for stimulus input and a relatively large amount of relevant information to be processed; thus, attention must be selective or divided. When this approach is applied to animals and alternative accounts have been ruled out, stronger evidence for selective or divided attention in animals has been found. Similar processes are thought to be involved when animals search more natural environments for targets. Finally, an attempt is made to distinguish these top-down attentional processes from more automatic preattentional processes that have been studied in humans and other animals.     

Spiritual and Religious Implications of Aging with HIV: A Conceptual and Methodological Review

ABSTRACT

Spirituality and religious practices can buffer people from stressful life circumstances and promote positive biopsychosocial outcomes. The beneficial effects of spirituality and religious practices have been documented in aging and HIV. Unfortunately, little is known about spirituality and religious practices in older adults with HIV. As the number of older adults with HIV increases, with an estimated 91,000 adults over 50 being diagnosed with this disease in the United States, spirituality and religious practices may help HIV-positive people to age successfully. Crisis competence and spiritual trajectories are ways of conceptualizing spiritual development when confronting aging with a life-changing event such as a being diagnosed with HIV. Methodological issues in studying spirituality in adults aging with HIV are identified including defining spirituality and religiosity, heterogeneity of the population, timing of diagnosis, mode of transmission, sexual orientation, religious and cultural stigma, and hardiness. Implications for possible interventions are also posited.     

心理疾病污名内隐测评的类别标签初探

采用单一类型内隐联想测验,考察以往研究中常用的概括化心理疾病词和具体心理疾病词作为心理疾病内隐污名间接测量概念词或类别标签的有效性。结果发现,相较于与积极词配对的任务,两类概念词与消极词（心理疾病态度词）配对的任务反应时更快,正确率更高。研究表明概括化概念和具体疾病与反映人们对心理疾病患者真实态度的消极词存在更紧密的自动联结,是人们头脑中表征心理疾病的概念词或类别标签,可作为内隐测量中的心理疾病概念词用于污名评估。     

The effect of personal and group discrimination on the subjective well-being of people with mental illness: the role of internalized stigma and collective action intention

The goal of this study is to test a model in which personal discrimination predicts internalized stigma, while group discrimination predicts a greater willingness to engage in collective action. Internalized stigma and collective action, in turn, are associated to positive and negative affect. A cross-sectional study with 213 people with mental illness was conducted. The model was tested using path analysis. Although the data supported the model, its fit was not sufficiently good. A respecified model, in which a direct path from collective action to internalized stigma was added, showed a good fit. Personal and group discrimination appear to impact subjective well-being through two different paths: the internalization of stigma and collective action intentions, respectively. These two paths, however, are not completely independent, as collective action predicts a lower internalization of stigma. Thus, collective action appears as an important tool to reduce internalized stigma and improve subjective well-being. Future interventions to reduce the impact of stigma should fight the internalization of stigma and promote collective action are suggested.     

Coping with Sexual Identity Stigma in the U.S. Military: An Examination of Identity Management Practices Prior to and After the Repeal of “Don’t Ask,Don’t Tell”

This study assesses the identity management strategies employed by gays, lesbians, and bisexuals in the U.S. military prior to and after the repeal of “Don’t Ask, Don’t Tell.” In-depth interviews were conducted with gay, lesbian, and bisexual service members and veterans. Data were analyzed using constant comparative analysis. Findings revealed that these service members made thoughtful and deliberate decisions about whether or not, and to whom, they would reveal their sexual identities. Identity concealment was practiced most often, even after the repeal, which was found to incite feelings of self-reproach, isolation, and stress. However, several new identity management strategies emerged after the repeal of “Don’t Ask, Don’t Tell” (i.e., strategies of openness) that stimulated positive self-feelings. By engaging in some level of openness, participants in this study were able to overcome some of the adverse effects of their minority stress.     

Assessment of a “Transgender Identity Stigma” scale among trans women in India: Findings from exploratory and confirmatory factor analyses

Background: Sexual minority stigma has been shown to influence mental health and sexual risk, but limited research is available on measuring transgender-identity stigma among trans women in India. We adapted an Exposure to Transphobia scale to the Indian context and tested a 14-item Transgender Identity Stigma Questionnaire (TGISQ) among trans women in India. We aimed to assess and validate the factor structure of the TGISQ and to assess its reliability.

Methods: Data were from a cross-sectional survey among 300 trans women (including hijras/thirunangais) from six urban/semi-urban sites in India. The TGISQ consisted of self-reported ratings on 14 items. We initially conducted exploratory factor analysis, using principal axis factoring (PAF) and promax rotation, and assessed reliability (internal consistency) using Cronbach's alpha; we then conducted confirmatory factor analysis to assess construct validity (factorial validity). Construct validity of the final 13-item Transgender Identity Stigma Scale (TGISS) was also examined by computing Pearson's correlations between TGISS and relevant theoretical constructs (e.g., depression, social support).

Results: PAF identified two factors: enacted stigma (5 items) and felt normative stigma (8 items). The final 13-item TGISS had high reliability and acceptable construct validity.

Conclusions: The TGISS was found to have adequate psychometric properties, making it the first valid and reliable scale to measure stigma and discrimination faced by trans women in India. Future studies can further refine TGISS, which might help in comparing the differences in stigma experiences among diverse subgroups of trans women, and in monitoring and evaluating the success of stigma reduction programs.     

Ignoring biased feedback: Membership in a stigmatized group as a moderator of mnemic neglect

A personal history of being the target of biased negative evaluation may lead individuals to habitually divert attention from negative feedback when it is possible to do so. Two studies tested for the first time the hypothesis that people belonging to a stigmatized group (Black students on a predominantly White campus) will, relative to non-stigmatized people, be more likely to engage in mnemic neglect—that is, they will reveal a greater tendency to insulate themselves from the effects of negative self-relevant feedback by means of motivated forgetting. The results of Study 1 supported that hypothesis. In Study 2, priming the concept of egalitarianism reduced the tendency of Black participants to engage in higher levels of mnemic neglect, consistent with the idea that the higher observed levels of mnemic neglect among stigmatized individuals derives from expecting biased, discriminatory responses from other people.

Risk and resilience: Dual effects of perceptions of group disadvantage among Latinos

Several decades of research on the psychology of minority status has yielded highly discrepant findings. Substantial research suggests that perceptions of discrimination are linked to inferior self-regard and poor mental health, whereas other studies indicate that perceptions of discrimination are protective of global self-esteem. We tested a theoretical model of the combined (negative/positive) effects of perceived group disadvantage on self-esteem among Latinos. Structural equation modeling analyses indicated that perceptions of group disadvantage were indirectly related to self-esteem through two principal pathways. The total (direct and indirect) effect on self-esteem was not significant, suggesting that, among Latinos, the deleterious consequences of perceived belonging to a devalued and disadvantaged group were fully counterbalanced by the positive effects of intervening variables. More complex models may be needed to characterize fully the self-protective and detrimental consequences of perceived group disadvantage among Latinos.
