Dissociative alterations in body image among individuals reporting out-of-body experiences: a conceptual replication

A conceptual replication of the link between self-reported dissociative alterations in body-image under experimental conditions and the reporting of prior out-of-body experiences in a recent data set was undertaken. Also examined was whether this relationship would hold for experiences reported during the experimental context and whether it is independent of self-reported New Age belief. Data from mostly undergraduates (N= 40; M age = 33.5, SD = 12.5; 27 women) in a mirror-gazing study were retrospectively analyzed. The 9 individuals who reported prior out-of-body experiences, relative to those 31 who did not, exhibited significantly greater self-reported dissociative alterations in body-image during the mirror-gazing task, even when the influence of scores on New Age belief was controlled for statistically. The same differential relationship was not found between 6 individuals who did and 34 who did not report out-of-body experiences during the task.     

Turning a deaf ear to fear: impaired recognition of vocal affect in psychopathic individuals

The processing of emotional expressions is fundamental for normal socialization and interaction. Reduced responsiveness to the expressions of sadness and fear has been implicated in the development of psychopathy (R. J. R. Blair, 1995). The current study investigates the ability of adult psychopathic individuals to process vocal affect. Psychopathic and nonpsychopathic adults, defined by the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991), were presented with neutral words spoken with intonations conveying happiness, disgust, anger, sadness, and fear and were asked to identify the emotion of the speaker on the basis of prosody. The results indicated that psychopathic inmates were particularly impaired in the recognition of fearful vocal affect. These results are interpreted with reference to the low-fear and violence inhibition mechanism models of psychopathy.     

Attribute Framing and Goal Framing Effects in Health Decisions

Levin, Schneider, and Gaeth (LSG, 1998) have distinguished among three types of framing—risky choice, attribute, and goal framing—to reconcile conflicting findings in the literature. In the research reported here, we focus on attribute and goal framing. LSG propose that positive frames should be more effective than negative frames in the context of attribute framing, and negative frames should be more effective than positive frames in the context of goal framing. We test this framework by manipulating frame valence (positive vs negative) and frame type (attribute vs goal) in a unified context with common procedures. We also argue that the nature of effects in a goal-framing context may depend on the extent to which the research topic has “intrinsic self-relevance” to the population. In the context of medical decision making, we operationalize low intrinsic self-relevance by using student subjects and high intrinsic self-relevance by using patients. As expected, we find complete support for the LSG framework under low intrinsic self-relevance and modified support for the LSG framework under high intrinsic self-relevance. Overall, our research appears to confirm and extend the LSG framework.     

Walton's Argumentation Schemes for Presumptive Reasoning: A Critique and Development

The aim of the paper is to advance the theory of argument or inference schemes by suggesting answers to questions raised by Walton's Argumentation Schemes for Presumptive Reasoning (1996), specifically on: the relation between argument and reasoning; distinguishing deductive from presumptive schemes, the origin of schemes and the probative force of their use; and the motivation and justification for their associated critical questions.     

Picking up the pace: effects of global temporal context on sensitivity to the tempo of auditory sequences

This article continues a line of research examining factors affecting listeners' auditory tempo sensitivities. Of particular interest is the question of whether listeners are sensitive to the overall (global) pace of their auditory environment and how this sensitivity may affect their perceptions of sequence timing. To address this question, we manipulated the set of sequence tempi (between 300 and 700 msec) that listeners experienced over the course of a 1-h period (i.e., the global temporal context) while they performed a tempo-discrimination task involving standard-comparison pairs of isochronous tone sequences. Overall findings show systematic distortions in perceived tempo that are consistent with the view that listeners adapt to the global pace of their auditory environments. Moreover, general support was found for the hypothesis that increasing the number of equal intervals in a standard sequence produces greater improvements in tempo sensitivity when the standard sequence tempo is different from the global pace than when it is at the global pace. Implications of these findings for models of timing and temporal processing are discussed.     

The amygdala and ventromedial prefrontal cortex in morality and psychopathy

Recent work has implicated the amygdala and ventromedial prefrontal cortex in morality and, when dysfunctional, psychopathy. This model proposes that the amygdala, through stimulus-reinforcement learning, enables the association of actions that harm others with the aversive reinforcement of the victims' distress. Consequent information on reinforcement expectancy, fed forward to the ventromedial prefrontal cortex, can guide the healthy individual away from moral transgressions. In psychopathy, dysfunction in these structures means that care-based moral reasoning is compromised and the risk that antisocial behavior is used instrumentally to achieve goals is increased.     

Intrapersonal and Interpersonal Factors Influencing Adolescents' Decisions About Having Sex: A Test of Sufficiency of the Theory of Planned Behavior1

This study tested the theory of planned behavior's (TPB) expectation that attitudes, social norms, and self‐efficacy would mediate other variables' effects on intention for having sex and probability of having sex. Longitudinal data were collected from 790 high‐school‐aged adolescents. In an intrapersonal variable model, sensation seeking, alcohol use, hard work, smoking, and moral beliefs had mediated effects, but the last 2 also had direct effects (on intention and behavior, respectively). In an interpersonal model, school attachment had mediated effects, pressure to have sex had a direct effect on behavior, and parent communication and number of sexually active friends had both. Intrapersonal variable effects were better described by the TPB than those of interpersonal variables. Targeting distal psychosocial factors may enhance intervention efficacy.     

A Review of Functional Analysis Methods Conducted in Public School Classroom Settings

The use of functional behavior assessments (FBAs) to address problem behavior in classroom settings has increased as a result of education legislation and long-standing evidence supporting function-based interventions. Although functional analysis remains the standard for identifying behavior–environment functional relations, this component is rarely included in FBAs in practice. To address this research-to-practice gap, we searched the FBA literature to identify studies including functional analyses (FAs) conducted in students’ usual classrooms and implemented by school personnel in public school settings. FAs were defined broadly as assessments involving systematic manipulation of one or more antecedent or consequent variable to evaluate environmental influences on student problem behavior. We identified 39 studies including FAs for 88 participants. All studies were coded with regard to FA approaches and procedures as well as student, classroom, and implementer characteristics. In addition, we evaluated the extent to which FA methods in the study sample aligned with previous recommendations to address practical barriers to implementation. Results revealed a range of FA approaches that varied according to student and classroom characteristics, as well as several strategies to address implementation barriers that have been under-utilized in classroom-based FAs to date.
