Gay Identity and HIV Risk for Black and Latino Men Who Have Sex with Men

Strong gay identity among white men who have sex with men (MSM) has been associated with decreased HIV risk, but data for black and Latino MSM (BLMSM) are inconclusive. We examined gay identity and HIV risk among BLMSM to inform social and structural HIV intervention strategies. BLMSM were administered a computerized survey as part of an HIV research study during 2011–2012 conducted in New York City. We used a brief scale of Gay Identity Questionnaire. After data analysis, Stage I (not fully accepting) and Stage II (fully accepting) gay identity were determined based on participant responses. We used logistic regression to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the association between gay identity with HIV risk and social determinant factors. Among 111 self-identified BLMSM (median age = 32 years, 68.4% with some college or higher education), 34.2% reported receptive anal sex without condoms in the previous three months. Gay Identity Questionnaire Scale assessment indicated that 22 (19.8%) were Stage I, and 85 (76.6%) were Stage II in this BLMSM sample. Stage II gay identity was more likely seen among BLMSM with high involvement in the gay community (aOR 3.2; CI 1.00, 10.26) and less likely among BLMSM who exchanged sex for food or shelter (aOR 0.15; CI 0.02, 0.98). Fully accepting gay identity may be protective for BLMSM as it relates to transactional sex; these factors warrant further research and consideration as part of HIV prevention strategies.     

Asthma-specific cognitions,self-focused attention,and fear of negative evaluation in adolescents and young adults diagnosed with childhood-onset asthma

The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning.     

Viral videos and virtue: Moral elevation inductions shift affect and interpersonal goals in daily life

Laboratory studies suggest that witnessing virtuous acts triggers moral elevation, an emotion characterized by feeling uplifted and increased prosocial motives. However, it remains unknown whether regular inductions can increase elevation and prosocial motives in daily life without being vulnerable to habituation or adaptation effects. Participants (total N = 181) were randomly assigned to elevating vs. neutral or amusing inductions (video or recall tasks) for seven days (Study 1), ten days (Study 2), or 12 days over one month (Study 3). Multilevel growth models showed that relative to comparison conditions, elevation inductions increased daily elevation, positive affect, and prosocial outcomes (compassionate goals and affiliation), and decreased self-protective motives (self-image goals). Adaptation effects occurred for immediate responses when exercises occurred daily, but not when spaced out over time, and not for outcomes measured later each day. Results suggest benefits of brief, regular elevation experiences and have implications for interventions targeting specific emotions.

Regulation of low-threshold afferent activity may contribute to short-term habituation in Aplysia californica

The goal of this study was to characterize the contribution of a population of low-threshold mechanoreceptors to short-term habituation of siphon-elicited reflex responses in Aplysia californica. Since the location of their somata is unknown, we refer to them as the Unidentified Low-Threshold mechanoreceptors (ULTs). The ULTs operate in parallel to the higher-threshold and well-characterized LE sensory neurons, yet little is known regarding their contribution to behavioral plasticity. Using extracellular recordings from the siphon nerve, we found that habituation training that favors ULT activation resulted in a significant decrease in afferent activity at training intervals up to 1 min per stimulus (1 min ISI). To determine how this reduction impacts responses at other sites of the reflex network, we used intracellular recordings to measure training-induced changes in either L29 excitatory interneurons or LFS siphon motor neurons. With a 30s ISI, changes at both locations were training site-specific and matched the rate of change of afferent activity, implicating regulated sensory activity as a primary mechanism. With a shorter training interval (1s ISI), site-specificity of training was not observed in the L29s, but was still preserved in the motor neurons. For both, the rate of change during training was faster than the rate of change of afferent activity. Taken together, we conclude that regulation of low-threshold sensory neuron activity can play a significant role in short-term habituation, but other network processes may be recruited at more rapid training intervals.     

Historical change, cultural learning, and cognitive representation in Zinacantec Maya children

Against the background of an unchanging sequence of representational development, we demonstrate that implicit processes of learning and cognition can change from one historical period to another. One generation of Zinacantec Maya children was studied in 1969 and 1970, the next generation in 1991 and 1993. In the intervening two decades, the community, located in Chiapas, Mexico, was involved in a transition from an economy based primarily on subsistence and agriculture to an economy based primarily on money and commerce. A naturalistic study of weaving apprenticeship and an experimental study of visual representation showed that the ecological transition was linked to greater emphasis on independent cultural learning, abstract representation, and innovation, and, correlatively, a movement away from scaffolded guidance, detail-oriented representation, and imitative representational strategies. These changes constituted automatic adaptations with an implicit nature. In addition, historical variability in implicit modes of cultural apprenticeship predicted shifts in implicit processes of child and adolescent cognition. In sum, socialization and development are not fixed but adapt, in a coordinated way, to changing ecological conditions.     

Spaced Retrieval Enhances Memory for a Name–Face–Occupation Association in Older Adults With Probable Alzheimer's Disease

The authors trained 4 older adults with probable Alzheimer's disease to recall a name–face–occupation association using the spaced retrieval technique. Six training sessions were administered over a 2-week period. On each trial, participants selected a target photograph and stated the target name and occupation at increasingly longer retention intervals, contingent upon successful recall. Two transfer tasks were included to determine whether the trained association transferred to the person whose picture served as the training stimulus. Results yielded a positive effect of spaced retrieval on memory for the trained association. Analyses of errors revealed that participants remembered the target person's occupation more often than his or her name. There was modest evidence of transfer of the name–face–occupation association to the actual person. Implications of these data for memory remediation and quality of life in cognitively impaired older adults are considered.     

The Role of Life Satisfaction in Predicting Student Engagement and Achievement

Much research has investigated how individual components of subjective well-being (e.g., life satisfaction, positive affect, negative affect) influence adolescent functioning. Little is known, however, about how the third component of subjective well-being (SWB), life satisfaction, contributes to positive adolescent outcomes when investigated simultaneously with positive and negative emotions. The current study extends Lewis et al.’s (J Psychoeduc Assess 27:397–408, 2009. doi:10.1177/0734282908330571) work by considering the incremental validity of life satisfaction (LS) relative to negative affect (NA) and positive affect (PA) as predictors of student engagement and achievement in a sample of middle school students. Results indicated LS provided incremental validity over affective states in predicting student engagement and some aspects of academic achievement. Gender also moderated these relationships. Practitioners are encouraged to include all components of SWB in assessments, especially when trying to understand students’ school functioning.     

A preliminary investigation on improving functional communication training by mitigating resurgence of destructive behavior

Despite the effectiveness and widespread use of functional communication training (FCT), resurgence of destructive behavior can occur if the functional communication response (FCR) contacts a challenge, such as lapses in treatment integrity. We evaluated a method to mitigate resurgence by conducting FCT using a multiple schedule of reinforcement prior to extinction. After functional analyses of 2 boys’ destructive behavior and treatment with FCT (Study 1), we compared levels of resurgence during an extinction challenge either after a typical FCT sequence or after exposure to schedule thinning in the context of a multiple‐schedule arrangement (Study 2). Results for both participants suggested that schedule thinning using discriminative stimuli in a multiple schedule mitigated the resurgence of destructive behavior.     

Integrating Fast and Frugal Heuristics with a Model of Memory‐based Cue Generation

Although the fast and frugal heuristics have been studied extensively, relatively little attention has been paid to how cues are generated to be used within the heuristics. The goal of this paper is to propose and test a memory‐based model of how cues are generated and used in cue‐based inferences. The current study advances theory by integrating the fast and frugal heuristics with HyGene, a memory‐based model of how decision makers generate and evaluate hypotheses. Using archival data in which memory retrieval variables were not directly manipulated, we demonstrate that participants' cue selection behavior is consistent with memory‐based retrieval. Further, by directly manipulating memory retrieval within a cue‐based stock‐forecasting task, we demonstrate that memory processes underlie cue use. Participants' cue use varied depending on the relationship between cue validity and the frequency with which the cues were seen during learning. The HyGene model provided the best account of the empirical data, providing further evidence for the critical role of memory in judgment and decision making. Copyright © 2018 John Wiley & Sons, Ltd.
