Counting to ten milliseconds: low-anger, but not high-anger, individuals pause following negative evaluations

Low-anger individuals are less reactive, both emotionally and behaviourally, to a large variety of situational primes to anger and aggression. Why this is so, from an affective processing perspective, has been largely conjectural. Four studies (total N=270) sought to link individual differences in anger to tendencies exhibited in basic affective processing tasks. On the basis of motivational factors and considerations, it was hypothesised that negative evaluations would differentially activate a psychological alarm system at low levels of anger, resulting in a pause that should be evident in the speed of making subsequent evaluations. Just such a pattern was evident in all studies. By contrast, high-anger individuals did not pause following their negative evaluations. In relation to this affective processing tendency, at least, dramatically different effects were observed among low- versus high-anger individuals. Implications for the personality-processing literature, theories of trait anger, and fast-acting regulatory processes are discussed.     

The effects of optimism and pessimism on updating emotional information in working memory

In the present study we elucidate the emotional and executive control interactions that might underlie optimism and pessimism. Participants completed a self-report measure of optimism/pessimism and performed an emotion faces categorisation task and an emotion n-back task in which they indicated whether each of a series of faces had the same or a different emotional expression (happy, sad, neutral) as the face presented two trials before. Trials were structured to measure latency to update emotional content in working memory (WM). More pessimistic individuals formed connections among positive stimuli, and broke connections among positive and sad stimuli, in WM more slowly than did less pessimistic individuals; levels of optimism/pessimism did not affect the rate with which individuals formed and broke connections among neutral representations in WM. It appears, therefore, that levels of pessimism are related to specific affective cognitive mechanisms in WM that may be involved in emotion regulation.     

Adjunctive mirror exposure for eating disorders: A randomized controlled pilot study

Mirror exposure therapy has proven efficacious in improving body image among individuals with shape/weight concerns and eating disorders. No randomized controlled trials have examined the effect of mirror exposure in a healthy-weight clinical sample of eating disordered individuals. The purpose of the current study was to test the efficacy of a five-session acceptance based mirror exposure therapy (A-MET) versus a non directive body image therapy (ND) control as an adjunctive treatment to outpatient eating disorder treatment. Thirty-three males and females aged 14–65 with a body mass index of 18.5–29.9 were randomized to five sessions of A-MET or ND with a 1-month follow-up. Results indicated large to moderate effect size differences for efficacy of A-MET across measures of body checking, body image dissatisfaction, and eating disorder symptoms (d = ?0.38 to ?1.61) at end of treatment and follow-up. Baseline measures of social comparison and history of appearance-related teasing were predictive of treatment response. There were also differential effects of treatment on participants' perceived homework quality, but no differences in therapeutic alliance. Results suggest that A-MET is a promising adjunctive treatment for residual body image disturbance among normal and overweight individuals undergoing treatment for an eating disorder. Future research and clinical implications are discussed.     

Effect of non-normality on test statistics for one-way independent groups designs

The data obtained from one‐way independent groups designs is typically non‐normal in form and rarely equally variable across treatment populations (i.e. population variances are heterogeneous). Consequently, the classical test statistic that is used to assess statistical significance (i.e. the analysis of variance F test) typically provides invalid results (e.g. too many Type I errors, reduced power). For this reason, there has been considerable interest in finding a test statistic that is appropriate under conditions of non‐normality and variance heterogeneity. Previously recommended procedures for analysing such data include the James test, the Welch test applied either to the usual least squares estimators of central tendency and variability, or the Welch test with robust estimators (i.e. trimmed means and Winsorized variances). A new statistic proposed by Krishnamoorthy, Lu, and Mathew, intended to deal with heterogeneous variances, though not non‐normality, uses a parametric bootstrap procedure. In their investigation of the parametric bootstrap test, the authors examined its operating characteristics under limited conditions and did not compare it to the Welch test based on robust estimators. Thus, we investigated how the parametric bootstrap procedure and a modified parametric bootstrap procedure based on trimmed means perform relative to previously recommended procedures when data are non‐normal and heterogeneous. The results indicated that the tests based on trimmed means offer the best Type I error control and power when variances are unequal and at least some of the distribution shapes are non‐normal.     

Parental and Secondary School Teachers’ Perceptions of ICT Professionals, Gender Differences and their Role in the Choice of Studies

The influence of parents and teachers in the decisions made by adolescents regarding study options has not been widely documented in Spain. The main aim of this qualitative study consisted of analyzing the opinions of parents and secondary school teachers about their role in the different academic and professional choices boys and girls make. Seven focus groups (4 with 27 parents and 3 with 22 secondary school teachers) from 5 schools located in urban and rural areas of Catalonia (Spain) were carried out in order to explore how both groups perceive Information and Communication Technology (ICT) professionals, gender differences in study options and their own role in adolescents’ choice of study options. Our findings show that parents and teachers hold stereotypes about ICTs and consider that gender does not condition adolescents’ study choices. Both groups saw themselves as playing a secondary role in adolescents’ academic and professional choices. Some gender differences among parents and teachers emerged regarding their perception of the ICT professionals and their own role and of others in shaping adolescents’ study choices.?The findings and their practical implications are discussed.     

Auditory-phonetic projection and lexical structure in the recognition of sine-wave words

Speech remains intelligible despite the elimination of canonical acoustic correlates of phonemes from the spectrum. A portion of this perceptual flexibility can be attributed to modulation sensitivity in the auditory-to-phonetic projection, although signal-independent properties of lexical neighborhoods also affect intelligibility in utterances composed of words. Three tests were conducted to estimate the effects of exposure to natural and sine-wave samples of speech in this kind of perceptual versatility. First, sine-wave versions of the easy and hard word sets were created, modeled on the speech samples of a single talker. The performance difference in recognition of easy and hard words was used to index the perceptual reliance on signal-independent properties of lexical contrasts. Second, several kinds of exposure produced familiarity with an aspect of sine-wave speech: (a) sine-wave sentences modeled on the same talker; (b) sine-wave sentences modeled on a different talker, to create familiarity with a sine-wave carrier; and (c) natural sentences spoken by the same talker, to create familiarity with the idiolect expressed in the sine-wave words. Recognition performance with both easy and hard sine-wave words improved after exposure only to sine-wave sentences modeled on the same talker. Third, a control test showed that signal-independent uncertainty is a plausible cause of differences in recognition of easy and hard sine-wave words. The conditions of beneficial exposure reveal the specificity of attention underlying versatility in speech perception.     

Internal attribution of outcome moderates the cortisol response to a cooperative task in women

Several ethological reports have indicated that cooperative behaviors play an adaptive role. However, research has focused on competition in men, and there have been few studies on cooperation. This study aims to analyze the cortisol and psychological responses in women to a cooperative situation compared with a competitive situation in a laboratory context. The sample was distributed into four groups depending on the task and the outcome obtained: Positive cooperation, negative cooperation, competition with victory, and competition with defeat. Our results show that, in comparison with competition, cooperation produces different effects in cortisol, but not in psychological states. Nevertheless, these effects occur only when the task outcome and its appraisal are considered. Only the participants who cooperated and obtained a positive outcome and those who competed and lost showed significant decrements of cortisol. Internal attribution was higher in groups with more stable cortisol levels, suggesting a possible modulator effect of controllability in the way the situation was experienced. These results could be generalized to situations in which negotiation, mediation, and cooperative strategies are relevant for making decisions and/or solving problems.     

The relation between overcommitment and burnout: does it depend on employee job satisfaction?

Using the Conservation of Resources (COR) theory as a framework, we hypothesized a maladaptive role played by overcommitment in the escalation of burnout. We further specified our model by testing an interaction effect of job satisfaction. By using a longitudinal design, we proposed a moderated mediational model in which burnout at Time 1 (T1) increases overcommitment, which in turn leads to more burnout one month later. We further expected to find a moderating role of job satisfaction in the link between overcommitment and burnout at Time 2 (T2). A group of 86 white-collar workers in personnel services in Italy (longitudinal response rate = 77.48%) participated in our study. The findings supported our hypotheses even when controlling for gender and role stressors. In particular, by using bootstrapping procedures to test mediation, we found evidence that employees reporting burnout tend to develop a maladaptive coping style, i.e., overcommitment, which in turn increases burnout over time. This relation was particularly strong for dissatisfied employees. These results highlight the importance of overcommitment for burnout escalation, as well as of job satisfaction, since it may mitigate, at least in the short term, the effect of such dysfunctional strategies.     

The Role of Parental Distress in Moderating the Influence of Child Neglect on Maladjustment

Despite pervasive evidence of the harmful impact of neglect on children’s adjustment, individual differences in adaptation persist. This study examines parental distress as a contextual factor that may moderate the relation between neglect and child adjustment, while considering the specificity of the relation between neglect and internalizing versus externalizing problems. In a sample of 66 children (33 with a documented child protective services history of neglect prior to age six), neglect predicted internalizing, and to a lesser extent externalizing, problems as rated by teachers at age seven. Parental distress moderated the relation between neglect and internalizing, but not externalizing, problems. Specifically, higher levels of neglect predicted more internalizing problems only among children of distressed parents. These findings indicate that parent-level variables are important to consider in evaluating the consequences of neglect, and point to the importance of considering contextual factors when identifying those children most at risk following neglect.
