The interplay of attention and emotion: top-down attention modulates amygdala activation in psychopathy

Psychopathic behavior has long been attributed to a fundamental deficit in fear that arises from impaired amygdala function. Growing evidence has demonstrated that fear-potentiated startle (FPS) and other psychopathy-related deficits are moderated by focus of attention, but to date, no work on adult psychopathy has examined attentional modulation of the amygdala or concomitant recruitment of relevant attention-related circuitry. Consistent with previous FPS findings, here we report that psychopathy-related differences in amygdala activation appear and disappear as a function of goal-directed attention. Specifically, decreased amygdala activity was observed in psychopathic offenders only when attention was engaged in an alternative goal-relevant task prior to presenting threat-relevant information. Under this condition, psychopaths also exhibited greater activation in selective-attention regions of the lateral prefrontal cortex (LPFC) than did nonpsychopaths, and this increased LPFC activation mediated psychopathy’s association with decreased amygdala activation. In contrast, when explicitly attending to threat, amygdala activation did not differ in psychopaths and nonpsychopaths. This pattern of amygdala activation highlights the potential role of LPFC in mediating the failure of psychopathic individuals to process fear and other important information when it is peripheral to the primary focus of goal-directed attention.     

Effectiveness of the Challenging Horizons After-School Program for young adolescents with ADHD

There are no empirically supported psychosocial treatments for adolescents with attention-deficit hyperactivity disorder (ADHD). This study examined the treatment benefits of the Challenging Horizons Program (CHP), a psychosocial treatment program designed to address the impairment and symptoms associated with this disorder in young adolescents. In addition to evaluating social and academic functioning outcomes, two critical questions from previous studies pertaining to the timing, duration, and family involvement in treatment were addressed. Forty-nine students recruited in two cohorts were randomly assigned to receive either the CHP or a community care condition. Outcomes suggested that students who received the CHP improved compared to students in the control condition on measures of symptoms and impairment. Implications related to timing, duration, and family involvement are reported, as well as recommendations for future studies.     

Gender differences in combat-related stressors and their association with postdeployment mental health in a nationally representative sample of U.S. OEF/OIF veterans

Though the broader literature suggests that women may be more vulnerable to the effects of trauma exposure, most available studies on combat trauma have relied on samples in which women's combat exposure is limited and analyses that do not directly address gender differences in associations between combat exposure and postdeployment mental health. Female service members' increased exposure to combat in Afghanistan and Iraq provides a unique opportunity to evaluate gender differences in different dimensions of combat-related stress and associated consequence for postdeployment mental health. The current study addressed these research questions in a representative sample of female and male U.S. veterans who had returned from deployment to Afghanistan or Iraq within the previous year. As expected, women reported slightly less exposure than men to most combat-related stressors, but higher exposure to other stressors (i.e., prior life stress, deployment sexual harassment). No gender differences were observed in reports of perceived threat in the war zone. Though it was hypothesized that combat-related stressors would demonstrate stronger negative associations with postdeployment mental health for women, only one of 16 stressor × gender interactions achieved statistical significance and an evaluation of the clinical significance of these interactions revealed that effects were trivial. Results suggest that female Operation Enduring Freedom/Operation Iraqi Freedom service members may be as resilient to combat-related stress as men. Future research is needed to evaluate gender differences in the longer-term effects of combat exposure.     

Atheists and Agnostics Negotiate Religion and Family

Through in‐depth interviews with scientists at elite academic institutions—those particularly likely to have no firm belief in God—we provide insight into the motives scientists who are not religious have for joining a religious group and the struggle faced by these individuals in reconciling personal beliefs with what they consider the best interests of their families. Narratives stress the use of resources from identities as scientists to provide their children with religious choices consistent with science and in negotiating spousal influence and a desire for community. Findings expand the religious socialization and identities literatures by widening the range of understanding of the strategies parents utilize to interface with religious communities as well as lead to more nuanced public understanding of how atheist and agnostic scientists relate to religious communities.     

Classical conditioning of autonomic fear responses is independent of contingency awareness

The role of contingency awareness in classical conditioning experiments using human subjects is currently under debate. This study took a novel approach to manipulating contingency awareness in a differential Pavlovian conditioning paradigm. Complex sine wave gratings were used as visual conditional stimuli (CS). By manipulating the fundamental spatial frequency of the displays, we were able to construct pairs of stimuli that varied in discriminability. One group of subjects was given an "easy" discrimination, and another was exposed to a "difficult" CS+ and CS-. A 3rd group was exposed to a stimulus that was paired with the unconditional stimulus (UCS) 50% of the time and served as a control. Skin conductance response (SCR) and continuous UCS expectancy data were measured concurrently throughout the experiment. Differential UCS expectancy was found only in the easy discrimination group. Differential SCRs were found in the easy discrimination group as well as in the difficult discrimination group, but not in the 50% contingency control. The difficult discrimination group did not exhibit differential UCS expectancy but did show clear differential SCR. These observations support a dual process interpretation of classical conditioning whereby conditioning on an implicit level can occur without explicit knowledge about the contingencies.

Lesions of the rat nucleus basalis magnocellularis disrupt appetitive-to-aversive transfer learning

Rats with selective lesions of the nucleus basalis magnocellularis (NBM) and sham-lesion control animals were tested in an operant appetitive-to-aversive transfer task. We hypothesized that NBM lesions would not affect performance in the appetitive phase, but that performance would be impaired during subsequent transfer to the aversive phase of the task. Additional groups of NBM lesion and control rats were tested in the avoidance condition only, where we hypothesized that NBM lesions would not disrupt performance. These hypotheses were based, on the argument that the NBM is not necessary for simple association learning that does not tax attention. Both the appetitive phase of the transfer task and the avoidance only task depend only on simple associative learning and are argued not to tax attention. Consequently, performance in these tasks was predicted to be spared following NBM lesions. Complex, attention-demanding associative learning, however, is argued to depend on the NBM. Performance, in the aversive phase of the transfer task is both attentionally demanding and associatively more complex than in either the appetitive or aversive tasks alone; thus, avoidance performance in the NBM lesion group was predicted to be impaired following transfer from prior appetitive conditioning. Results supported our hypotheses, with the NBM lesion group acquiring the appetitive response normally, but showing impaired performance following transfer to the aversive conditioning phase of the transfer task. Impairments were not attributable to disrupted avoidance learning per se, as avoidance behavior was normal in the NBM lesion group tested in the avoidance condition only.     

Job‐Seeker Reactions to Selection Process Information in Job Ads

Using a policy‐capturing methodology, the current study examines if and to what extent individuals utilize selection process information contained in job ads in making evaluations of organizational attractiveness and decisions to apply. Results show both indirect and direct evidence that individuals do attend to and use these cues when presented in job ads in making initial job‐pursuit evaluations. Additionally, the results are consistent with a model derived from the organizational justice literature suggesting that perceptions of selection procedures' measurement accuracy may drive the observed effects. Specifically, ratings of organizational attractiveness and intentions to apply were significantly associated with perceptions of a given selection method's assessment accuracy for those ads that specified its use. Policy‐capturing results also show direct evidence that participants attend to and rely on selection process information in job ads to make job‐pursuit evaluations, and that perceptions of measurement accuracy are related to the degree to which, and how those cues are utilized. Research and applied implications are discussed.     

Transformational consumption choices: building an understanding by integrating social identity and multi‐attribute attitude theories

• Transformational value offerings result when marketers bundle products, services, and experiences in ways that provide consumers with opportunities to alter who they are. Examples include universities, healthcare providers, travel and leisure services, and many other businesses that guide individuals to change in some desired and lasting way. Pine and Gilmore ( 1999 ) predict that in the emerging economy “…transformation offerings will emerge across almost every industry that today views itself as part of the service sector” (p. 168). By definition, transformational value offerings involve identity development. Thus, it makes sense to use identity related variables to explain transformational value offering choices. This paper tests a model merging social identity theory and multi‐attribute attitude modeling to better understand factors predicting consumers' intentions to select a transformational value offering. A survey sample of United States Army Reserve recruits was used to test the integrated model. Results show that identity‐related perceptions form the basis for evaluating the value offering's benefits and intentions to adopt the offering. The prospective consumer also considers whether his or her self‐concept can accommodate that role. The proposed blending of social identity and multiattribute attitude models provides a promising framework for understanding and investigating consumers' choices to adopt transformational value offerings.
