Interoceptive fear conditioning and panic disorder: the role of conditioned stimulus-unconditioned stimulus predictability

Interoceptive fear conditioning is at the core of contemporary behavioral accounts of panic disorder. Yet, to date only one study has attempted to evaluate interoceptive fear conditioning in humans (see Acheson, Forsyth, Prenoveau, & Bouton, 2007). That study used brief (physiologically inert) and longer-duration (panicogenic) inhalations of 20% CO(2)-enriched air as an interoceptive conditioned (CS) and unconditioned (US) stimulus and evaluated fear learning in three conditions: CS only, CS-US paired, and CS-US unpaired. Results showed fear conditioning in the paired condition, and fearful responding and resistance to extinction in an unpaired condition. The authors speculated that such effects may be due to difficulty discriminating between the CS and the US. The aims of the present study are to (a) replicate and expand this line of work using an improved methodology, and (b) clarify the role of CS-US discrimination difficulties in either potentiating or depotentiating fear learning. Healthy participants (N=104) were randomly assigned to one of four conditions: (a) CS only, (b) contingent CS-US pairings, (c) unpaired CS and US presentations, or (d) an unpaired "discrimination" contingency, which included an exteroceptive discrimination cue concurrently with CS onset. Electrodermal and self-report ratings served as indices of conditioned responding. Consistent with expectation, the paired contingency and unpaired contingencies yielded elevated fearful responding to the CS alone. Moreover, adding a discrimination cue to the unpaired contingency effectively attenuated fearful responding. Overall, findings are consistent with modern learning theory accounts of panic and highlight the role of interoceptive conditioning and unpredictability in the etiology of panic disorder.     

Using I³ theory to clarify when dispositional aggressiveness predicts intimate partner violence perpetration

Deriving hypotheses from I3 theory (pronounced "I-cubed theory"), the authors conducted 4 studies to clarify the circumstances under which dispositional aggressiveness predicts intimate partner violence (IPV) perpetration. Consistent with the hypothesis that this link would be stronger when inhibitory processes are weak rather than strong, Studies 1 and 2 demonstrated that dispositional aggressiveness was an especially robust predictor of IPV perpetration among people experiencing self-regulatory strength depletion. Consistent with the hypothesis that this Dispositional Aggressiveness × Inhibition interaction effect would be stronger when instigating triggers are strong rather than weak, Studies 3 and 4 demonstrated that dispositional aggressiveness was an especially robust predictor of IPV perpetration among people characterized by both weak inhibition (poor executive control in Study 3, depletion in Study 4) and strong instigation (provocation in both studies). These effects were robust in studies employing experimental and nonexperimental designs, cross-sectional and longitudinal methods, dating and married participants, self-report and behavioral measures of IPV perpetration, and diverse operationalizations of all constructs. Discussion emphasizes the importance of incorporating instigating, impelling, and inhibiting processes into theoretical and empirical analyses of IPV perpetration.     

Predictors of responses to stress among families coping with poverty-related stress

This study tested how poverty-related stress (PRS), psychological distress, and responses to stress predicted future effortful coping and involuntary stress responses one year later. In addition, we explored age, sex, ethnicity, and parental influences on responses to stress over time. Hierarchical linear modeling analyses conducted with 98 low-income families (300 family members: 136 adults, 82 school-aged children, 82 adolescents) revealed that primary control coping, secondary control coping, disengagement, involuntary engagement, and involuntary disengagement each significantly predicted future use of that response. Primary and secondary control coping also predicted less maladaptive future responses to stress, while involuntary responses to stress undermined the development of adaptive responding. Age, sex, and interactions among PRS and prior coping were also found to predict certain responses to stress. In addition, child subgroup analyses demonstrate the importance of parental modeling of coping and involuntary stress responses, and warmth/nurturance and monitoring practices. Results are discussed with regard to the implications for preventive interventions with families in poverty.     

Ambivalence, communication and past use: understanding what influences women's intentions to use contraceptives

Unintended pregnancy among women in the 18-30 age group is a public health concern. The Extended Parallel Process Model (EPPM) provides a framework for exploring how women's perceptions of threat, efficacy, and fear influence intentions to use contraceptives. Past use and communication with best friends and partners were also considered. A telephone survey of 18-30-year-old women (N = 599) was completed. After univariate and bivariate analyses were conducted, the variables were entered into a hierarchal, multi-variate linear regression with three steps consistent with the EPPM to predict behavioral intention. The first step included the demographic variables of relationship status and income. The constructs for the EPPM were entered into step 2. Step 3 contained the fear measure. The model for the third step was significant, F(10,471) = 36.40, p < 0.001 and the variance explained by this complete model was 0.42. Results suggest that perceived severity of the consequences of an unintended pregnancy (p < 0.01), communication with friends (p < 0.01) and last sexual partner (p < 0.05), relationship status (p < 0.01), and past use (p < 0.001) were associated with women's intentions to use contraceptives. A woman's perception of the severity was related to her intention to use contraceptives. Half of the women (50.3%) reported ambivalence about the severity of an unintended pregnancy. In our study, talking with their last sexual partner had a positive effect on intentions to use contraceptives, while talking with friends influenced intentions in a negative direction. These results reconfirm the need for public health practitioners and health care providers to consider level of ambivalence toward unintended pregnancy, communication with partner, and relationship status when trying to improve women's contraceptive behaviors. Implications for effective communication interventions are discussed.

Narcissism and Empathy in Young Offenders and Non‐offenders

Understanding the individual factors that predispose persons to criminal behaviour is vital to reducing offending and rehabilitating those who have been sentenced to prison. This study examined the roles of narcissism (at both clinical and subclinical trait levels) and empathy, by comparing levels in young adult males currently serving a prison sentence to those with no history of criminal convictions. Prison participants had significantly higher levels of narcissism—in particular entitlement—than control participants, and this link was sequentially mediated by lower perspective‐taking and subsequently lack of empathic concern. Trait narcissism showed stronger effects than narcissistic personality disorder symptoms. Narcissistic young men's feelings of entitlement and ensuing lack of empathy for others may account for their greater likelihood of criminal behaviour. Copyright © 2013 John Wiley & Sons, Ltd.     

Reply to Rouder (2014): Good frequentist properties raise confidence

Established psychological results have been called into question by demonstrations that statistical significance is easy to achieve, even in the absence of an effect. One often-warned-against practice, choosing when to stop the experiment on the basis of the results, is guaranteed to produce significant results. In response to these demonstrations, Bayes factors have been proposed as an antidote to this practice, because they are invariant with respect to how an experiment was stopped. Should researchers only care about the resulting Bayes factor, without concern for how it was produced? Yu, Sprenger, Thomas, and Dougherty (2014) and Sanborn and Hills (2014) demonstrated that Bayes factors are sometimes strongly influenced by the stopping rules used. However, Rouder (2014) has provided a compelling demonstration that despite this influence, the evidence supplied by Bayes factors remains correct. Here we address why the ability to influence Bayes factors should still matter to researchers, despite the correctness of the evidence. We argue that good frequentist properties mean that results will more often agree with researchers’ statistical intuitions, and good frequentist properties control the number of studies that will later be refuted. Both help raise confidence in psychological results.
