Age-related declines in the fidelity of newly acquired category representations

We present a theory suggesting that the ability to build category representations that reflect the nuances of category structures in the environment depends upon clustering mechanisms instantiated in an MTL-PFC-based circuit. Because function in this circuit declines with age, we predict that the ability to build category representations will be impaired in older adults. Consistent with this prediction, we find that older adults are impaired relative to younger adults at learning nuanced category structures that contain exceptions to the rule. Model-based analysis reveals that this deficit arises from older adults' failure to engage clustering mechanisms to separate exception and rule-following items in memory.     

Striatal and hippocampal entropy and recognition signals in category learning: simultaneous processes revealed by model-based fMRI

Category learning is a complex phenomenon that engages multiple cognitive processes, many of which occur simultaneously and unfold dynamically over time. For example, as people encounter objects in the world, they simultaneously engage processes to determine their fit with current knowledge structures, gather new information about the objects, and adjust their representations to support behavior in future encounters. Many techniques that are available to understand the neural basis of category learning assume that the multiple processes that subserve it can be neatly separated between different trials of an experiment. Model-based functional magnetic resonance imaging offers a promising tool to separate multiple, simultaneously occurring processes and bring the analysis of neuroimaging data more in line with category learning's dynamic and multifaceted nature. We use model-based imaging to explore the neural basis of recognition and entropy signals in the medial temporal lobe and striatum that are engaged while participants learn to categorize novel stimuli. Consistent with theories suggesting a role for the anterior hippocampus and ventral striatum in motivated learning in response to uncertainty, we find that activation in both regions correlates with a model-based measure of entropy. Simultaneously, separate subregions of the hippocampus and striatum exhibit activation correlated with a model-based recognition strength measure. Our results suggest that model-based analyses are exceptionally useful for extracting information about cognitive processes from neuroimaging data. Models provide a basis for identifying the multiple neural processes that contribute to behavior, and neuroimaging data can provide a powerful test bed for constraining and testing model predictions.     

Is Conservative Religiousness Inherently Associated with Poorer Health for Sexual Minorities?

Results of path analysis involving sexual minority participants (N?=?1317) from diverse sociopolitical contexts revealed health outcomes to be associated with internalized homonegativity and the resolution of conflict between religious and sexual minority identities. Contrary to expectations, several markers of religiousness were not directly associated with either improved or worsened health outcomes for depression or anxiety. However, religious activity moderated the influence of internalized homonegativity (IH) on depression such that IH was less strongly related to depression among individuals who frequently attended religious services than among individuals who infrequently attended religious services. These findings have special salience for advancing a more accurate understanding of conservatively religious sexual minorities and directing culturally sensitive research, clinical services, and public policy.

     

A Comparison of Rubrics for Identifying Empirically Supported Practices with Single-Case Research

The use of single-case research methods for validating academic and behavioral interventions has gained considerable attention in recent years. As such, there has been a proliferation of methods for evaluating whether, and to what extent, primary research reports provide evidence of intervention effectiveness. Despite the recent interest in harnessing single-case research to identify empirically supported strategies, examination of these tools has revealed that there is a lack of consistency in the methodological criteria sampled and scoring procedures used to evaluate primary research reports. The present study examined the extent to which various evidence rubrics addressed specific methodological features of single-case research and classified studies into similar evidence categories. Results indicated that the methodological criteria included within rubrics tended to vary, particularly for criteria related to determining the generality of the intervention under study. Moreover, there was substantial discordance observed in the evidence classifications assigned to reviewed studies. These findings are discussed in the context of the still-developing nature of single-case evidence reviews. Recommendations for both research and practice are provided.     

Organizational Impression Management: Utilizing Anticipatory Tactics

The current pair of studies are the first to empirically show that the proposed tactics/processes (i.e., accommodation, legitimation, intimidation, bureaucratic) of the anticipatory organizational impression management (OIM) model decrease initial challenges to an event and prevent the escalation of an already existing challenge. Moreover, our data showed that variables specified by the model mediated the relationship between the tactics and the respective dependent measures (i.e., initial challenges, escalation of challenges). Our results offer compelling evidence for the OIM model, an empirical case that has been heretofore absent from the literature.     

State emotional clarity and attention to emotion: a naturalistic examination of their associations with each other,affect, and context

ABSTRACT

Despite emotional clarity and attention to emotion being dynamic in nature, research has largely focused on their trait forms. We examined the association between state and trait forms of these two constructs, and how they are related to affect intensity and two contextual variables: Social context and significant event occurrence. Seventy-nine adults recruited from the community reported eight times a day for a week on the extent to which they were clear about their emotions, attended to their emotions, levels of affect intensity, the number of people with whom they were interacting, and whether a significant event had occurred. State clarity and attention were positively associated, demonstrating a moderate relation similar to that of their trait forms. Trait and state attention, but not trait and state clarity, were significantly positively associated. Positive and negative affect were quadratically associated with clarity and attention, with the highest levels of affect intensity reported at high levels of clarity and attention. Clarity and attention were positively associated with increasing numbers of people with whom people were interacting. Attention and clarity were elevated when significant events occurred – especially during positive events. We discuss the findings in the context of functional adaptation theories of emotion.     

No Means Yes? Perpetuating Myths in the Sexological Construction of Women's Desire

The diagnosis and treatment of desire disorders are contentious issues within sexual medicine today. The issue of women's sexual desire (or rather lack of sexual desire) in particular, has highlighted a variety of problems within the current diagnostic framework for sexual dysfunctions. In an effort to rectify some of these problems, the concept of receptivity has been put forward by a number of clinicians with the suggestion that this better reflects women's experiences of desire. It is argued here, however, that he concept of receptivity presents serious problems for women in heterosexual relationships. Rather than helping women, furthering this concept may simply reinforce male sexual demands, curtail women's sexual autonomy, and promote coercive sex as an acceptable norm. It should therefore not be adopted by therapists.     

The symbolic identity implications of inter and intra‐group transgressions

The current investigation proposes that symbolic identity concerns underlie retributive desires following a transgression, but that the type of identity concern that primarily drives that retribution varies between intra and intergroup contexts. More specifically, a respondent's social identity may be threatened by calling into question his or her ingroup's status and power in the larger superordinate society, a concern that is particularly relevant in intergroup contexts. Identity may also be threatened by questioning a group's identity‐defining values, a concern that is particularly relevant in intragroup contexts. In support of these assertions, the current study shows that desires for retribution following an intergroup terrorist attack were stronger when the attack was framed as attempting to undermine the victimized nation's status/power, but were stronger following an intragroup terrorist attack when framed as attempting to undermine national values. Moreover, these differences only occurred for respondents high in national identification, underscoring that the effects are based on identity processes.

The Departure Status of Youth from Residential Group Care: Implications for Aftercare

Youth departing from out-of-home care settings face numerous challenges as they adapt to new settings or return to placements that have been unsuccessful in the past. Although several thousand youth face this transition annually, little is known about their specific needs and risks at departure. To better identify needs and risks, we evaluated the discharge data of 640 youth served in a residential group care setting by addressing the following questions: (a) to what settings do youth depart following a stay in residential group care, (b) what are the demographic, family, educational, behavioral, and departure characteristics of youth at departure, and (c) do these characteristics differ for youth departing to different levels of restrictiveness? Results indicate significant differences on youth characteristics based on levels of restrictiveness at departure placement. As one might expect, youth departing to more restrictive placements presented a broad host of challenges across domains, while those departing to less restrictive settings demonstrated fewer needs and departed with greater educational and behavioral gains. Results provide support for the development and planning of targeted aftercare programs designed to promote the short and long term functioning of youth served in out-of-home care.
