Subjective Importance of Masculinity as a Factor in Understanding Risky Sexual Attitudes and Behaviors among Sexual Minority Men

Sex Roles - In the present study we evaluated relationships among internalized stigma, subjective importance of masculine gender roles, and risky sexual attitudes and behaviors among men who...     

Evaluating the boundaries of analytic efficiency and control: A consecutive controlled case series of 26 functional analyses

We conducted this study to determine if the efficiency of the functional analysis could be improved without detrimental effects on control. In Experiment 1, we reanalyzed functional analyses conducted for the problem behavior of 18 children. We analyzed rates of problem behavior during the first 5 min and first 3 min of the original 10-min sessions and evaluated if changes in the level of control over problem behavior by the programmed contingency were evident from the analyses of shorter session duration. In Experiment 2, we conducted 8 consecutive functional analyses with 3-min sessions to further evaluate the utility of brief session durations. We found that control over problem behavior was demonstrated when conducting functional analyses with sessions as brief as 3 min.     

A note on Dasgupta’s Generalism

Philosophical Studies - Dasgupta (Philos Stud Int J Philos Anal Tradit 145(1):35–67, 2009) has argued that material individuals, such as particles and laptops, are metaphysically...     

Prioritization within visual working memory reflects a flexible focus of attention

When motivated, people can keep nonrecent items in a list active during the presentation of new items, facilitating fast and accurate recall of the earlier items. It has been proposed that this occurs by flexibly orienting attention to a single prioritized list item, thus increasing the amount of attention-based maintenance directed toward this item at the expense of other items. This is manipulated experimentally by associating a single distinct feature with a higher reward value, such as a single red item in a list of black items. These findings may be more parsimoniously explained under a distinctiveness of encoding framework rather than a flexible attention allocation framework. The retrieval advantage for the prioritized list position may be because the incongruent feature stands out in the list perceptually and causes it to become better encoded. Across three visual working memory experiments, we contrast a flexible attention theory against a distinctiveness of encoding theory by manipulating the reward value associated with the incongruent feature. Findings from all three experiments show strong support in favor of the flexible attention theory and no support for the distinctiveness of encoding theory. We also evaluate and find no evidence that strategy use, motivation, or tiredness/fatigue associated with reward value can adequately explain flexible prioritization of attention. Flexible attentional prioritization effects may be best understood under the context of an online attentional refreshing mechanism.

     

An Examination of the Glover Numbing Scale: Expanding the Content Validity of Posttraumatic Numbing

Quantification of posttraumatic numbing (PTN) has largely been limited to the assessment of a small number of items taken directly from the DSM. The current study takes steps to expand the content validity of PTN through examination of the Glover Numbing Scale (GNS), one of the few available measures specific to PTN. Specifically, the factor structure of the GNS and its convergence with DSM-based indices of PTN were examined in a sample of motor vehicle accident survivors (MVA; N = 288). Whereas the 5-factor structure originally proposed by Glover et al. Anxiety 1:70–79 (1994) evidenced a poor fit to the sample data, exploratory analysis suggested a 1-factor structure underlying data collected from the sample. Furthermore, GNS scores derived from this solution evidenced a strong convergent relationship with DSM-based PTN. These data suggest that alternative indicators contained within the GNS may be used to expand current conceptualizations of PTN.

Race Bias Tracks Conception Risk Across the Menstrual Cycle

ABSTRACT— Although a considerable body of research explores alterations in women's mating-relevant preferences across the menstrual cycle, investigators have yet to examine the potential for the menstrual cycle to influence intergroup attitudes. We examined the effects of changes in conception risk across the menstrual cycle on intergroup bias and found that increased conception risk was positively associated with several measures of race bias. This association was particularly strong when perceived vulnerability to sexual coercion was high. Our findings highlight the potential for hypotheses informed by an evolutionary perspective to generate new knowledge about current social problems—an avenue that may lead to new predictions in the study of intergroup relations.     

Why do narcissists take more risks? Testing the roles of perceived risks and benefits of risky behaviors

Much prior research demonstrates that narcissists take more risks than others, but almost no research has examined what motivates this behavior. The present study tested two potential driving mechanisms of risk-taking by narcissists (i.e., heightened perceptions of benefits and diminished perceptions of risks stemming from risky behaviors) by administering survey measures of narcissism and risk-taking to a sample of 605 undergraduate college students. Contrary to what might be expected, the results suggest that narcissists appreciate the risks associated with risky behaviors just as much as do less narcissistic individuals. Their risk-taking appears to instead be fueled by heightened perceptions of benefits stemming from risky behaviors. These results are consistent with a growing body of evidence suggesting that narcissists engage in some forms of potentially problematic behaviors, such as risk-taking, because of a surplus of eagerness rather than a deficit of inhibition.     

Multiple cognitive control effects of error likelihood and conflict

Recent work on cognitive control has suggested a variety of performance monitoring functions of the anterior cingulate cortex such as errors, conflict, error likelihood, and others. Given the variety of monitoring effects, a corresponding variety of control effects on behavior might be expected. This paper explores whether conflict and error likelihood produce distinct cognitive control effects on behavior, as measured by response time. A Change signal task (Brown & Braver, Science 307:1118–1121, 2005) was modified to include conditions of likely errors due to tardy as well as premature responses in conditions with and without conflict. The results discriminate between competing hypotheses of independent versus interacting conflict and error likelihood control effects. Specifically, the results suggest that the likelihood of premature versus tardy response errors can lead to multiple distinct control effects, which are independent of cognitive control effects driven by response conflict. As a whole, the results point to the existence of multiple distinct cognitive control mechanisms and challenge existing models of cognitive control that incorporate only a single control signal.     

Dual-process morality and the personal/impersonal distinction: A reply to McGuire, Langdon, Coltheart, and Mackenzie

A substantial body of research supports a dual-process theory of moral judgment, according to which characteristically deontological judgments are driven by automatic emotional responses, while characteristically utilitarian judgments are driven by controlled cognitive processes. This theory was initially supported by neuroimaging and reaction time (RT) data. McGuire et al. have reanalyzed these initial RT data and claim that, in light of their findings, the dual-process theory of moral judgment and the personal/impersonal distinction now lack support. While McGuire and colleagues have convincingly overturned Greene et al.’s interpretation of their original RT data, their claim that the dual-process theory now lacks support overstates the implications of their findings. McGuire and colleagues ignore the results of several more recent behavioral studies, including the study that bears most directly on their critique. They dismiss without adequate justification the results of a more recent neuroimaging study, three more recent patient studies, and an emotion-induction study. Their broader critique is based largely on their conflation of the dual-process theory with the personal/impersonal distinction, which are independent.
