Transmission risk behaviors in a subset of HIV-positive individuals: The role of narcissistic personality features

Most people living with HIV/AIDS (PLWHA) take steps to protect their sexual partners. However, a minority of PLWHA continue to engage in sexual risk behaviors that might contribute to the transmission of HIV. Psychiatric conditions, including certain pathological traits, are associated with sexual risk behaviors. Research examining the association between narcissistic traits as they relate to HIV transmission risk is limited. In the present study, 303 PLWHA were recruited from an infectious disease clinic and completed questionnaires assessing narcissistic characteristics, substance use, sexual risk behavior, and intentions to use condoms in the future. Narcissistic traits predicted unprotected sex with partners who are HIV-negative or whose HIV status was unknown as well as lower intentions to use condoms, after controlling for demographic factors and substance use. Interventions focused on reducing the transmission of HIV should take into account associations between sexual risk behavior and narcissism.     

Defective stimulus set attention in generalized epilepsy

This study examined auditory selective attention in primary generalized and complex-partial (temporal lobe) epileptics using binaural and dichotic versions of the Continuous Performance Test. The patient groups did not differ from normal controls when only one channel was presented or when divided attention (simultaneously monitoring two channels) was required. However, generalized epileptics had significantly depressed hit rates when directed attention (responding to critical stimuli in only one channel) was required. These results suggest a contribution of brain stem “arousal” mechanisms to stimulus set attention. In addition, right ear perceptual advantages were found on these dichotic monitoring tasks, lending support to the contention that short-term auditory memory and verbal report are not required for the dichotic ear effect.     

Iranian Herbalists,But Not Cooks,Are Better at Naming Odors Than Laypeople

Odor naming is enhanced in communities where communication about odors is a central part of daily life (e.g., wine experts, flavorists, and some hunter‐gatherer groups). In this study, we investigated how expert knowledge and daily experience affect the ability to name odors in a group of experts that has not previously been investigated in this context—Iranian herbalists; also called attars—as well as cooks and laypeople. We assessed naming accuracy and consistency for 16 herb and spice odors, collected judgments of odor perception, and evaluated participants' odor meta‐awareness. Participants' responses were overall more consistent and accurate for more frequent and familiar odors. Moreover, attars were more accurate than both cooks and laypeople at naming odors, although cooks did not perform significantly better than laypeople. Attars' perceptual ratings of odors and their overall odor meta‐awareness suggest they are also more attuned to odors than the other two groups. To conclude, Iranian attars—but not cooks—are better odor namers than laypeople. They also have greater meta‐awareness and differential perceptual responses to odors. These findings further highlight the critical role that expertise and type of experience have on olfactory functions.     

Exploring Counselor-Client Agreement on Clients’ Work Capacity in Established and Consultative Dyads

Counselor-client agreement on the work capacity of clients living with serious mental illnesses informs the counseling relationship and facilitates accurate assessments of client eligibility for public programs. In this exploratory mixed-methods study, we assessed counselor-client agreement on clients’ work capacity in 61 established therapeutic dyads and compared it with 30 dyads involved in an initial assessment session. Intraclass correlation coefficients and mountain plots were used to examine counselor-client agreement. Results revealed moderate counselor-client agreement of work capacity for both dyads. Counselor interviews illuminated sources of discordance. These results have practical implications for assessing the work capacity of clients.     

Task related modulation of the motor system during language processing

Recent neurophysiological and brain imaging studies have shown that the motor system is involved in language processing. However, it is an open question whether this involvement is a necessary requisite to understand language or rather a side effect of distinct cognitive processes underlying it. In order to clarify this issue we carried out three behavioral experiments, using a go-no go paradigm. Italian verbs expressing hand actions, foot actions or an abstract content served as stimuli. Participants used their right hands to respond. In Experiment 1, in which a semantics decision task with an early delivery of the go signal (during processing language material) was used, slower responses were found for hand action-related verbs than for foot action-related verbs. In Experiment 2, using the same task with either an early or a delayed delivery of the go signal (when language material had been already processed), no difference was found between responses to the two verb categories in the delayed delivery condition. In Experiment 3, in which a lexical decision task with an early delivery of the go signal was used, again no difference between the two verb categories was found. The present findings demonstrate that during language processing the modulation of the motor system crucially occurs while performing a semantics decision task, thus supporting the notion that this involvement is a necessary step to understand language rather than a side effect of upstream cognitive processes.     

En-Gendering the Couple-Deity Relationship: Clinical Implications of Power and Process

Spiritual practices are increasingly accommodated by therapists working with religious couples. While research documents potential benefits, spiritual practices such as prayer may invoke an interpretive couple-God relationship distorted by pathogenic processes in one or both spouses. A survey administered to 78 religious couples examined the influence of power/gender as it relates to couples’ harmful triangulation with Deity. Results suggest that harmful triangulation with Deity does occur to some degree in couple relationships, that there are significant differences by gender, and that spouses’ tendencies to triangulate are correlated with one another. We discuss these results from a systemic-feminist perspective, and offer some clinical applications for working with religious couples.

Sellars and Quine on empiricism and conceptual truth1

I compare Sellars’s criticism of the ‘myth of the given’ with Quine’s criticism of the ‘two dogmas’ of empiricism, that is, the analytic–synthetic distinction and reductionism. In Sections I to III, I present Quine’s and Sellars’s views. In IV to X, I discuss similarities and differences in their views. In XI to XII, I show that Sellars’s arguments against the ‘myth of the given’ are incompatible with Quine’s rejection of the analytic–synthetic distinction.     

Attention flexibly trades off across points in time

Sensory signals continuously enter the brain, raising the question of how perceptual systems handle this constant flow of input. Attention to an anticipated point in time can prioritize visual information at that time. However, how we voluntarily attend across time when there are successive task-relevant stimuli has been barely investigated. We developed a novel experimental protocol that allowed us to assess, for the first time, both the benefits and costs of voluntary temporal attention when perceiving a short sequence of two or three visual targets with predictable timing. We found that when humans directed attention to a cued point in time, their ability to perceive orientation was better at that time but also worse earlier and later. These perceptual tradeoffs across time are analogous to those found across space for spatial attention. We concluded that voluntary attention is limited, and selective, across time.     

Sexism and gender inequality across 57 societies

Theory predicts that individuals' sexism serves to exacerbate inequality in their society's gender hierarchy. Past research, however, has provided only correlational evidence to support this hypothesis. In this study, I analyzed a large longitudinal data set that included representative data from 57 societies. Multilevel modeling showed that sexism directly predicted increases in gender inequality. This study provides the first evidence that sexist ideologies can create gender inequality within societies, and this finding suggests that sexism not only legitimizes the societal status quo, but also actively enhances the severity of the gender hierarchy. Three potential mechanisms for this effect are discussed briefly.
