Avoidance Behavior Following Terror Event Exposure: Effects of Perceived Life Threat and Jewish Religious Coping

The current research was designed to examine associations of perceived life threat (PLT) and religious coping with the development of avoidance behavior following terror event exposure. Based upon the terror management theory (TMT), we hypothesized that religious coping, through its effect on religious beliefs as a meaning system, would moderate the impact of threat, as expressed in PLT, on an individual's reaction to terror event exposure, as manifested in avoidance behavior. Participants were 591 Israeli Jewish students who were vicariously or directly exposed to a terror event in the past. We report a significant interaction between PLT and negative religious coping. PLT was positively associated with avoidance behavior but this relationship was more profound among persons who reported high negative religious coping. Secular students reported higher rates of avoidance behavior and negative religious coping and were more likely than religious students to report intrapersonal religious conflict. Our findings suggest that terror event exposure is associated with an elevated sense of threat, which is, at least in part, associated with a weakening of prior religious beliefs.     

Exposure-based cognitive behavior therapy for anxiety related to asthma: A feasibility study with multivariate baseline design

In the presence of asthma, the risk of having an anxiety disorder is increased twofold. The few trials conducted on cognitive behavior therapy (CBT) for anxiety and asthma have mainly targeted panic disorder, and with mixed results. Experimental laboratory research indicates that increased anxiety may lead to hypervigilance toward asthma. Hence, fear and avoidance associated with increased anxiety due to asthma may be an important treatment target. A treatment that learn participants to differentiate between anxiety and asthma through gradual exposure to situations that risk triggering anxiety for asthma may be a possible avenue. As a first step to investigate this issue further, we developed a 10-week exposure-based CBT protocol for anxiety related to asthma and tested it in six participants using multivariate baseline design with repeated assessments throughout treatment. All participants reported satisfaction with treatment, as well as subjective overall improvement after treatment. Visual analysis, using graphs over each individual's trajectory, as well as potential efficacy on group level analyzing standardized mean change, indicated improvements in important outcomes. We conclude that exposure-based CBT is feasible and may improve anxiety related to asthma. Further investigation under randomized controlled trial conditions is warranted.     

Cumulative trauma,emotion reactivity and salivary cytokine levels following acute stress in healthy women

Background and Objectives: To better understand how trauma leads to poor health, this study examined whether cumulative trauma and emotion reactivity contribute to pro- (IL-1β) and anti-inflammatory (IL-10) salivary cytokine levels after stress.

Design: Seventy-three women, screened to be physically and mentally healthy, completed an acute stress paradigm and measures of lifetime trauma exposure.

Method: Saliva was collected 10?min before (i.e., baseline) and 35?min after the onset of a 10-min stressor. State negative and positive emotion were measured at baseline and post-stress.

Results: Most participants reported exposure to at least one trauma, with a mean of five. Cumulative trauma was associated with higher post-stress IL-1β and IL-1β/IL-10, but not with IL-10 or changes in emotion. Declines in positive emotion correlated with greater post-stress IL-1β.

Conclusions: These findings suggest that both cumulative trauma exposure and positive emotion have implications for salivary cytokine responses to acute stress. The inclusion of healthy women strengthens internal validity, and increases confidence that observed associations between trauma and salivary cytokine responses can be attributed to trauma, rather than to confounding health problems. This study adds to the growing literature examining how trauma may connect to cytokines, and ultimately, poor health.     

A placebo-controlled randomized trial of D-cycloserine augmentation of cue exposure therapy for smoking cessation

Recent studies underscore the importance of studying d-cycloserine (DCS) augmentation under conditions of adequate cue exposure treatment (CET) and protection from reconditioning experiences. In this randomized trial, we evaluated the efficacy of DCS for augmenting CET for smoking cessation under these conditions.

Sixty-two smokers attained at least 18 hours abstinence following 4 weeks of smoking cessation treatment and were randomly assigned to receive a single dose of DCS (n=30) or placebo (n=32) prior to each of two sessions of CET. Mechanistic outcomes were self-reported cravings and physiologic reactivity to smoking cues. The primary clinical outcome was 6-week, biochemically-verified, continuous tobacco abstinence.

DCS, relative to placebo, augmentation of CET resulted in lower self-reported craving to smoking pictorial and in vivo cues (d = 0.8 to 1.21) in a relevant subsample of participants who were reactive to cues and free from smoking-related reconditioning experiences. Select craving outcomes were correlated with smoking abstinence, and DCS augmentation was associated with a trend toward a higher continuous abstinence rate (33% vs. 13% for placebo augmentation).

DCS augmentation of CET can significantly reduce cue-induced craving, supporting the therapeutic potential of DCS augmentation when applied under appropriate conditions for adequate extinction learning.     

Is ideology the enemy of inquiry? Examining the link between political orientation and lack of interest in novel data

Four studies examined the relationship between political orientation and data selection. In each study participants were given the opportunity to select data from a large data set addressing a specific issue: the justness of the world (Pilot Study), the efficacy of social safety nets (Studies 1–3), and the benefits of social media (Study 3). Participants were given no knowledge of what the data would tell them in advance. More conservative participants selected less data, and in Study 3 this relationship was partly accounted for by an increased tendency to question the value of science as a way of learning about the world. These findings may reveal one factor contributing to political polarization: an asymmetrical interest in scientific data.     

Gender differences in implicit exposure to cyber-pornography

ABSTRACT

Cyber-pornography consumption has become a widespread behavioral habit, with potential diverse outcomes for the user. Previous studies have repeatedly found that males are exposed to cyber-pornography more than females, when they are asked about it explicitly. However, perceived social acceptance of cyber-pornography consumption may dramatically bias such explicit reports. The current study aimed at better understanding gender differences in exposure to cyber-pornography using both explicit self-report measures and a new measure developed to examine exposure to cyber-pornography indirectly. The findings demonstrated gender differences in exposure to cyber-pornography in both measures. Women tended to understate the extent of their exposure. Interestingly, men showed the opposite tendency. Lastly, perceived social acceptance mediated the relationship between gender and explicit report bias. We discuss the conclusions of the current study in relation to previous theories and findings, as well as the importance of using indirect measures to study socially controversial topics such as cyber-pornography.     

Early language outcomes in Argentinean toddlers: Associations with home literacy,screen exposure and joint media engagement

This study aimed to analyse the contribution of mothers' home literacy beliefs and practices and the quantity and quality of screen media exposure on Argentinean toddler's language. In addition, we considered parent–child joint engagement, as well as adult scaffolding behaviours during the use of electronic devices. A total of 465 mothers of 18–36 months old children completed an online survey including: the MacArthur Bates CDI, home literacy, screen exposure, joint engagement and scaffolding questionnaires. We observed positive effects of literacy beliefs, PC times and verbal scaffolding on language outcomes. TV exposure contributed negatively to vocabulary and, along with educational content, to sentence use. Shared reading and screen media experiences can be an opportunity for language stimulation, provided there is dialogue and joint engagement. Passive screen exposure and inadequate content may be detrimental for toddlers' language outcomes, probably by displacement of socially significant interactions.     

When All Is Revealed: A Dissociation between Evaluative Learning and Contingency Awareness

Three experiments are reported that address the issue of awareness in evaluative learning in two different sensory modalities: visual and haptic. Attempts were made to manipulate the degree of awareness through a reduction technique (by use of a distractor task in Experiments 1 and 2 and by subliminally presenting affective stimuli in Experiment 3) and an induction technique (by unveiling the evaluative learning effect and requiring participants to try to discount the influence of the affective stimuli). The results indicate overall that evaluative learning was successful in the awareness-reduction groups but not in the awareness-induction groups. Moreover, an effect in the opposite direction to that normally observed in evaluative learning emerged in participants aware of the stimulus contingencies. In addition, individual differences in psychological reactance were found to be implicated in the strength and direction of the effect. It is argued that these results pose serious problems for the contention that awareness is necessary for evaluative learning.
