Posttraumatic Cognitions and Depressive Symptoms in War and Disaster Affected Widows in Sri Lanka: The Role of Community Support

In this study the authors evaluated the associations between war- and disaster-related problems and indicators of psychological distress (posttraumatic cognitions and culturally-specific symptoms of depression) among a sample of Tamil widows in the Eastern Provence of Sri Lanka. Furthermore, community support was evaluated as a mediator of these associations. Surveys were administered to women (N?=?156) in an interview format by trained research assistants who were native Tamil speakers. Mediation hypotheses were evaluated using path analysis. Results showed that war-related problems, but not disaster-related losses, was significantly associated with community support and posttraumatic cognitions, such that higher number of war-problems was associated with lower community support and more posttraumatic cognitions. Community support had a significant negative association with posttraumatic cognitions and depression. Additionally, we found evidence that war-related problems was indirectly associated with depression through community support. Although the magnitude of associations was small, results suggest that contextual problems resulting from years of armed conflict may be associated with less support from one’s community which, in turn, is associated with increased psychological distress. Limitations and implications for intervention and future research are discussed.     

The role of shape recognition in figure/ground perception in infancy

In this study we sought to determine whether infants, like adults, utilize previous experience to guide figure/ground processing. After familiarization to a shape, 5-month-olds preferentially attended to the side of an ambiguous figure/ground test stimulus corresponding to that shape, suggesting that they were viewing that portion as the figure. Infants’ failure to exhibit this preference in a control condition in which both sides of the test stimulus were displayed as figures indicated that the results in the experimental condition were not due to a preference between two figure shapes. These findings demonstrate for the first time that figure/ground processing in infancy is sensitive to top-down influence. Thus, a critical aspect of figure/ground processing is functional early in life.     

Testing for negligible interaction: A coherent and robust approach

Researchers often want to demonstrate a lack of interaction between two categorical predictors on an outcome. To justify a lack of interaction, researchers typically accept the null hypothesis of no interaction from a conventional analysis of variance (ANOVA). This method is inappropriate as failure to reject the null hypothesis does not provide statistical evidence to support a lack of interaction. This study proposes a bootstrap‐based intersection–union test for negligible interaction that provides coherent decisions between the omnibus test and post hoc interaction contrast tests and is robust to violations of the normality and variance homogeneity assumptions. Further, a multiple comparison strategy for testing interaction contrasts following a non‐significant omnibus test is proposed. Our simulation study compared the Type I error control, omnibus power and per‐contrast power of the proposed approach to the non‐centrality‐based negligible interaction test of Cheng and Shao (2007, Statistica Sinica, 17, 1441). For 2 × 2 designs, the empirical Type I error rates of the Cheng and Shao test were very close to the nominal α level when the normality and variance homogeneity assumptions were satisfied; however, only our proposed bootstrapping approach was satisfactory under non‐normality and/or variance heterogeneity. In general a × b designs, although the omnibus Cheng and Shao test, as expected, is the most powerful, it is not robust to assumption violation and results in incoherent omnibus and interaction contrast decisions that are not possible with the intersection–union approach.     

Quadratic Associations Between Empathy and Depression as Moderated by Emotion Dysregulation

Empathic tendencies have been associated with interpersonal and psychological benefits, but empathy at extreme levels or in combination with certain personal characteristics may contribute to risk for depression. This study tested the moderating role of cognitive emotion regulation in depression's association with empathy using nonlinear models. Young adults (N = 304; 77% female; M = 19 years) completed measures of cognitive emotion regulation strategies, depression, and affective and cognitive empathy. Individuals with good regulation had low levels of depression overall and their depression symptoms were lowest when levels of affective empathy were average. Individuals with poor regulation had high levels of depression overall, particularly when levels of empathy were moderate to high. Extremely high and low levels of cognitive empathy were associated with elevated depression, and this association was not moderated by regulation. These findings suggest tendencies to respond empathically to others’ needs is neither an adaptive nor maladaptive characteristic but rather moderate empathy, particularly in the context of good regulation, may offer the greatest protection against depression.     

An evaluation of resurgence following functional communication training conducted in alternative antecedent contexts via telehealth

Treatments based on differential reinforcement may inadvertently increase the recurrence of problem behavior in the face of challenges because reinforcers for appropriate behavior occur in the same context as problem behavior. The current study evaluated one potential approach to mitigating these problems with differential reinforcement treatments based on behavioral momentum theory. Specifically, appropriate behavior was trained in contexts without a history of reinforcement prior to intervening with problem behavior. Participants were 4 children with autism spectrum disorder. Treatment used telehealth to implement functional communication training (FCT) in three alternative contexts with minimal or no history of reinforcement for problem behavior before initiating FCT in the treatment context. Evaluations of the effects of treatment and tests of resurgence were conducted intermittently during treatment to evaluate maintenance. When FCT treatment was initiated in alternative contexts, initial results were comparable to more typical implementations of FCT. Resurgence was reduced to similar levels during tests of resurgence for all participants when compared to more typical previously published implementations of FCT, but clinically significant reductions in resurgence occurred more quickly in the present study. These findings support training appropriate behavior in an alternative context to mitigate the resurgence of problem behavior during differential reinforcement treatments.     

Asking an eyewitness to predict their later lineup performance could harm the confidence–accuracy relationship

Few studies have investigated eyewitnesses' ability to predict their later lineup performance, known as predecision confidence. We applied calibration analysis in two experiments comparing predecision confidence (immediately after encoding but prior to a lineup) to postdecision confidence (immediately after a lineup) to determine which produces a superior relationship with lineup decision accuracy. Experiment 1 (N = 177) featured a multiple-block lineup recognition paradigm featuring several targets and lineups; Experiment 2 featured an eyewitness identification paradigm with a mock-crime video and a single lineup for each participant (N = 855). Across both experiments, postdecision confidence discriminated well between correct and incorrect lineup decisions, but predecision confidence was a poor predictor of accuracy. Moreover, simply asking for predecision confidence weakened the postdecision confidence–accuracy relationship. This implies that police should exercise caution when interviewing eyewitnesses, as they should not be asked to predict their ability to make an accurate lineup decision.     

Initial outcomes of an augmented competing stimulus assessment

Competing stimulus assessments (CSAs) are designed to identify stimuli that, when made freely available, reduce problem behavior. Although CSAs have demonstrated utility, identifying competing stimuli can be difficult for some individuals. The current study describes outcomes from an augmented CSA (A-CSA) for 6 consecutively encountered cases with treatment-resistant subtypes of automatically maintained problem behavior. When test stimuli were made freely available, only between 0 and 1 effective competing stimuli were identified for each case. Prompting and response blocking were temporarily employed in succession to promote engagement with stimuli and disrupt problem behavior. When those procedures were withdrawn and stimuli made freely available, the number of effective competing stimuli increased in all 6 cases. Findings suggest that procedures designed to promote engagement and disrupt problem behavior may allow the A-CSA to be a platform not only for identifying competing stimuli, but also for actively establishing competing stimuli.
