A Social Problem-Solving Model of Adherence to HIV Medications.

HIV medication adherence remains a challenge and limits the degree to which treatment benefit can be maximized. This study tested an explanatory model of HIV medication adherence using a social problem-solving (SPS) framework. Associations of SPS with adherence are hypothesized to be direct and/or indirect via psychological health. HIV+ adults were interviewed using validated measures of SPS, psychological health, and antiretroviral therapy (ART) medication adherence. Structural equation modeling (SEM) techniques were used to test hypothesized relationships and to evaluate overall fit of the model to the data. SEM supported an indirect association (but not direct) of SPS on adherence via psychological health among the 545 HIV+ adults included in the analyses. Overall, the findings resulted in a model of adherence that offered very good fit to the data and correctly classified 97% of the cases as adherent versus nonadherent. Results support the use of SPS as a conceptual framework for understanding adherence to ART. Findings offer rationale and direction for SPS interventions to enhance adherence by improving psychological health. Such approaches, if effective, have the potential to positively impact psychological well being and adherence, thereby maximizing clinical benefit from treatment, which is linked to lower mortality from AIDS.     

Sender Demeanor: Individual Differences in Sender Believability Have a Powerful Impact on Deception Detection Judgments

Sender demeanor is an individual difference in the believability of message senders that is conceptually independent of actual honesty. Recent research suggests that sender demeanor may be the most influential source of variation in deception detection judgments. Sender demeanor was varied in five experiments (N = 30, 113, 182, 30, and 35) to create demeanor–veracity matched and demeanor–veracity mismatched conditions. The sender demeanor induction explained as much as 98% of the variance in detection accuracy. Three additional studies (N = 30, 113, and 104) investigated the behavioral profiles of more and less believable senders. The results document the strong impact of sender effects in deception detection and provide an explanation of the low‐accuracy ceiling in the previous findings.     

Detection and Localization of Magazine Insertion Clicks in Various Environmental Noises

The early detection and accurate localization of threatening sounds is vital for the survival of military personnel. The purpose of the present study was to investigate the detection, localization, and response time to an M-16 rifle magazine insertion click in three background conditions: jungle, pink, and ambient noise. The level of the click varied from -18 to 0 dB signal-to-noise ratio (SNR). Reported results indicate that detection rates of 50, 70, and 100% required SNRs of ?6 to ?12, ?3, and 0 dB, respectively. Localization accuracy of 50 and 80% within a ±15° angle required SNRs of about ?6 and 0 dB, respectively; 100% accuracy was never achieved. Response time was about 2.0–2.5 s for high SNRs but increased gradually at poorer SNRs. The military relevance of the reported findings is discussed.     

Defining and Measuring Mechanisms of Change in Psychological Therapies: The Path Not Taken

Metcalf and Dimidjian (this issue) have provided an important review of the current evidence base for mindfulness‐based cognitive therapy (MBCT) and presented a helpful summary of the proposed mechanisms of change. It is necessary to engage in a continuous dialogue regarding the evidence base for change mechanisms, and the article by Metcalf and Dimidjian highlights an important barrier of concern to the field of treatment outcome research. The present commentary aims to expand the discussion regarding the definition, measurement, and evaluation of “mechanisms of change.” Using MBCT as an example, this commentary addresses the ambiguity surrounding the definition and operationalisation of these mechanisms in research on psychological therapies and how the method of measurement may impact the results obtained in clinical trials. It is argued that a potentially fruitful avenue of future research would involve investigation of techniques, important client‐therapeutic processes, and mechanisms in a single study in order to comprehensively evaluate how change occurs.     

Knowledge of response location alone is not sufficient to generate social inhibition of return

Previous research has revealed that the inhibition of return (IOR) effect emerges when individuals respond to a target at the same location as their own previous response or the previous response of a co-actor. The latter social IOR effect is thought to occur because the observation of co-actor's response evokes a representation of that action in the observer and that the observation-evoked response code subsequently activates the inhibitory mechanisms underlying IOR. The present study was conducted to determine if knowledge of the co-actor's response alone is sufficient to evoke social IOR. Pairs of participants completed responses to targets that appeared at different button locations. Button contact generated location-contingent auditory stimuli (high and low tones in Experiment 1 and colour words in Experiment 2). In the Full condition, the observer saw the response and heard the auditory stimuli. In the Auditory Only condition, the observer did not see the co-actor's response, but heard the auditory stimuli generated via button contact to indicate response endpoint. It was found that, although significant individual and social IOR effects emerged in the Full conditions, there were no social IOR effects in the Auditory Only conditions. These findings suggest that knowledge of the co-actor's response alone via auditory information is not sufficient to activate the inhibitory processes leading to IOR. The activation of the mechanisms that lead to social IOR seems to be dependent on processing channels that code the spatial characteristics of action.     

A Muslim President? Misperceptions of Barack Obama's Faith in the 2008 Presidential Campaign

Rumors that President Barack Obama is a Muslim were rampant during the 2008 presidential campaign and continued well into his presidency. These rumors were widely believed, were electorally consequential, and are part of a growing trend of politically motivated misconceptions. Thus, relying principally on the theory of motivated reasoning, we examine the factors that shaped citizens’ beliefs about and responses to messages about Obama's faith. Using an original survey experiment and data from the 2008–2009 American National Election Study panel, we show that citizens’ responses to rumors about Obama's religion were shaped by political predispositions, political awareness, and their interactions. Identification of Obama with Islam was most widespread, and the cues encouraging such identification were most successful, among individuals with low levels of political awareness, conservative and Republican identifications, and negative views of cultural out‐groups. Viewing Obama as Muslim was significantly less prevalent among people with high levels of awareness and with the opposite set of predispositions.     

Common Heritable Effects Underpin Concerns Over Norm Maintenance and In‐Group Favoritism: Evidence From Genetic Analyses of Right‐Wing Authoritarianism and Traditionalism

Research has shown that in‐group favoritism is associated with concerns over the maintenance of social norms. Here we present two studies examining whether genetic factors underpin this association. A classical twin design was used to decompose phenotypic variance into genetic and environmental components in two studies. Study 1 used 812 pairs of adult U.S. twins from the nationally representative MIDUS II sample. Study 2 used 707 pairs of middle‐age twins from the Minnesota Twin Registry. In‐group favoritism was measured with scales tapping preferences for in‐group (vs. out‐group) individuals; norm concerns were measured with the Multidimensional Personality Questionnaire–Traditionalism (Study 1) and Right‐Wing Authoritarianism (RWA; Study 2) scales. In Study 1, heritable effects underlying traditionalism were moderately (c. 35%) overlapping with the genetic variance underpinning in‐group favoritism. In Study 2, heritable influences on RWA were entirely shared with the heritable effects on in‐group favoritism. Moreover, we observed that Big Five Openness shared common genetic links to both RWA and in‐group favoritism. These results suggest that, at the genetic level, in‐group favoritism is linked with a system related to concern over normative social practices, which is, in turn, partially associated with trait Openness.     

An Interpersonal Approach to Religiousness and Spirituality: Implications for Health and Well‐Being

The interpersonal tradition (Horowitz & Strack, 2011) provides a rich conceptual and methodological framework for theory‐driven research on mechanisms linking religiousness and spirituality (R/S) with health and well‐being. In three studies, we illustrate this approach to R/S. In Studies 1 and 2, undergraduates completed various self‐report measures of R/S, interpersonal style, and other aspects of interpersonal functioning. In Study 3, a community sample completed a wide variety of R/S measures and a measure of interpersonal style. Many, but not all, aspects of religiousness (e.g., overall religiousness, intrinsic religiousness) were associated with a warm interpersonal style, and most aspects and measures of spirituality were associated with a warm and somewhat dominant style. Spirituality and related constructs (i.e., gratitude, compassion) were associated with interpersonal goals that emphasize positive relationships with others, and with beneficial interpersonal outcomes (i.e., higher social support, less loneliness, and less conflict). However, some aspects of R/S (e.g., extrinsic religiousness, belief in a punishing God) were associated with a hostile interpersonal style. R/S have interpersonal correlates that may enhance or undermine health and emotional adjustment. This interpersonal perspective could help clarify why some aspects of religiousness and spirituality are beneficial and others are not.
