Emotional reactivity and cognitive regulation in anxious children

Recent models of anxiety disorders emphasize abnormalities in emotional reactivity and regulation. However, the empirical basis for this view is limited, particularly in children and adolescents. The present study examined whether anxious children suffer both negative emotional hyper-reactivity and deficits in cognitive emotion regulation. Participants were 49 children aged 10-17 with generalized anxiety disorder, social anxiety, or separation anxiety disorder as their primary diagnosis, as well as 42 age- and gender-matched non-anxious controls. After completing a diagnostic interview and self-report questionnaires, participants were presented with pictures of threatening scenes with the instructions either to simply view them or to use reappraisal, a cognitive emotion regulation strategy, to decrease their negative emotional response. Emotion ratings, content analysis of reappraisal responses, and reports of everyday use of reappraisal were used to assess negative emotional reactivity, reappraisal ability, efficacy and frequency. Relative to controls, children with anxiety disorders (1) experienced greater negative emotional responses to the images, (2) were less successful at applying reappraisals, but (3) showed intact ability to reduce their negative emotions following reappraisal. They also (4) reported less frequent use of reappraisal in everyday life. Implications for the assessment and treatment of childhood anxiety disorders are discussed.     

Travel and residual emotional well-being

This study addresses the question of how work commutes change positive versus negative and active versus passive mood experienced after the commutes. Analyses are presented for 230 time-sampled morning commutes to work, made by 146 randomly sampled people in three different Swedish cities, asking them to use smartphones to report mood before, directly after, and later in the work place after the commute. The results show that self-reported positive emotional responses evoked by critical incidents are related to mood changes directly after the commute but not later in the day. It is also shown that satisfaction with the commute, measured retrospectively, is related to travel mode, travel time, as well as both positive and negative emotional responses to critical incidents.     

Systematic review of stress-related injury vulnerability in athletic and occupational contexts

Injury is a pervasive, expensive and, to some extent, preventable problem. Stress is a psychological risk factor for injury but little is known about how stress processes compare in athletic and occupational contexts. This paper reviews research on stress-related injury vulnerability in athletic and occupational contexts to characterize and compare samples, methods, and conclusions from the perspective of an integrated model of stress-related injury vulnerability. A comprehensive search of four major databases identified research in both athletic (n = 34) and occupational contexts (n = 22). Studies were coded to extract characteristics of the samples, research designs, measures, and conclusions about stress-injury relations. Studies used more prospective than cross-sectional or case control research designs. Injury was most frequently defined as missing one subsequent day of training or work (35.7%). Approximately 75% of the identified studies in each context indicated a positive association between stress and injury occurrence. The consistency of findings suggested a robust stress-related injury vulnerability for both exposures and responses, however, caution is warranted due to the diversity of measures and surveillance periods and the lack of experimental designs. New hypotheses are identified to refine models of stress-related injury vulnerability in athletic and occupational contexts.     

Counter-regulation triggered by emotions: Positive/negative affective states elicit opposite valence biases in affective processing

The present study investigated whether counter-regulation in affective processing is triggered by emotions. Automatic attention allocation to valent stimuli was measured in the context of positive and negative affective states. Valence biases were assessed by comparing the detection of positive versus negative words in a visual search task (Experiment 1) or by comparing interference effects of positive and negative distractor words in an emotional Stroop task (Experiment 2). Imagining a hypothetical emotional situation (Experiment 1) or watching romantic versus depressing movie clips (Experiment 2) increased attention allocation to stimuli that were opposite in valence to the current emotional state. Counter-regulation is assumed to reflect a basic mechanism underlying implicit emotion regulation.     

Normalized demand for drugs and other reinforcers.

The concepts of behavioral economics have proven to be useful for understanding the environmental control of overall levels of responding for a variety of commodities, including reinforcement by drug self-administration. These general concepts have implications for the assessment of abuse liability and drug abuse intervention and the formulation of public policy on drug abuse. An essential requirement is the ability to compare the demand for different drugs directly in order to assess relative abuse liability, and to compare demand for the same drug under different environmental and biological interventions to assess their ability to reduce demand. Until now, such comparisons were hampered by the confounding effect of varying drug doses and potencies that prevent quantitative comparisons of demand elasticity--sensitivity of consumption and responding to the constraint of price (effort). In this paper we describe a procedure to normalize demand-curve analysis that permits dose- and potency-independent comparisons of demand across drugs. The procedure is shown to be effective for comparing drug demand within and across the drug classes. The technique permits a quantitative ordering of demand that is consistent with the peak levels of responding maintained by the drugs. The same technique is generalized for the comparison of other types of reinforcers under different biological conditions.     

Event-related brain potentials reveal differences in emotional processing in alexithymia

ABSTRACT

The inability to recognise and describe emotions in the self is known as Alexithymia. In the present study we used event-related potentials (ERPs) to examine the locus of processing emotional differences in alexithymia. We tested men, both those scoring high (score?>?61) and controls who scored low (score?<?51) on the Toronto Alexithymia Scale-20 on an emotional face discrimination task. We assessed three ERP components: P1 (an index of early perceptual processing), N170 (an index of early facial processing) and P3 (an index of late attentional suppression). While controls showed a stronger P3 effect for angry faces relative to happy and neutral faces, Alexithymic men showed no significant differences in P3 across emotions. Alexithymic men showed delayed P1 and N170 amplitudes compared to controls. These results suggest that the locus of processing differences between alexithymic men and controls occur both early in perceptual processing and later in conscious processing.     

The effects of emotional stimuli on target detection: indirect and direct resource costs

The present study was designed to explore the performance costs of negative emotional stimuli in a vigilance task. Forty participants (20 women) performed a vigilance task in two conditions: one with task-irrelevant negative-arousing pictures and one with task-irrelevant neutral pictures. In addition to performance, we measured subjective state (energetic arousal, tense arousal, task-related and task-unrelated thoughts) and frontal cerebral activity with near infrared spectroscopy. Overall performance in the negative picture condition was lower than in the neutral picture condition and the negative picture condition had elevated levels of energetic arousal, tense arousal and task-related thoughts. Moreover, there was a significant relationship between the impact of the negative pictures on tense arousal and task-related thoughts and the impact of the negative pictures on performance (in comparison to the neutral picture stimuli task). These results provide support for indirect cost models of negative emotional stimuli on target detection performance.     

Emotion understanding,pictorial representations of friendship and reciprocity in school-aged children

This study examined the relationship between emotional understanding, friendship representation and reciprocity in school-aged children. Two hundred and fifty-one Caucasian 6-year-old children (111 males and 140 females) took part in the study. The Test of Emotion Comprehension (TEC) and the Pictorial Assessment of Interpersonal Relationships (PAIR) were used. Children having a reciprocal friendship and children having a unilateral friendship with a child named as their “best friend” were compared on the emotional understanding task and on their pictorial representations of friendship. Multilevel analyses indicated that friendship status effects were not influenced by classroom-level differences. Results showed that children with reciprocal friendships drew themselves as more similar to and more cohesive with their best friends, and they showed better understanding of emotions, than children having a unilateral friendship. Finally, the implications of these findings for theoretical and empirical research development on friendship are discussed.
