The role of Gray's impulsivity in anxiety‐mediated differences in resistance to extinction

Choice behaviour and extinction learning were studied in a group of 108 undergraduates classified according to the Sensitivity to Punishment and Sensitivity to Reward scales (that measure Gray's anxiety and impulsivity dimensions, respectively). The learning task consisted of continuous choosing between two response alternatives: one was continuously reinforced with a small reward and the other was partially reinforced with a greater reward. After 200 trials, one of the responses remained as in the previous phase, and the other was never rewarded in order to attain extinction. The main aims of the study were: (i) to replicate Avila's finding of lesser resistance to extinction of subjects having high scores on the Sensitivity to Punishment scale; (ii) to investigate whether impulsives (subjects having high scores on the Sensitivity to Reward scale) chose more than non‐impulsives the response associated with a continuous, small reward; and (iii) to test, following the model of Patterson and Newman, whether impulsive subjects had a great resistance to extinction of responses highly associated with reward. Results supported all three predictions. Discussion is based on the compatibility of the models of disinhibition of Gray and of Patterson and Newman. Copyright © 2000 John Wiley & Sons, Ltd.     

Testing the Relationship Between Parents’ and Their Children’s Subjective Well-Being

Casas et al. (J Happiness Stud 9(2):197–205, 2008) found no significant relationship between paired answers given by parents and their 12–16-year-old children (N?=?266) for a single-item scale on overall life satisfaction (OLS). However, a significant, but low (.19) parent–child relationship did appear for the PWI multi-item scale. Overall, children reported higher subjective well being than parents. In this article, we present the results obtained from confirmatory factor analysis (CFA), using more scales and a bigger sample (N?=?1,250) of paired parents and children. The study uses three multiple-item scales: the PWI, the SWLS and the BMSLSS, and six single-item scales: the OLS, two items from Russell’s scale on core affects, one on overall happiness, Fordyce’s happiness item and the optional item of the BMSLSS on overall life satisfaction. Separate CFA for each of the 3 multi-item scales showed good fit statistics. In order to check comparability between parents and children, we tested equal loading and intercept constraints. The models with restricted loadings fit only for the PWI and BMSLSS, but none of the models with restricted intercepts fit. Therefore, it was only possible to estimate two factor correlations for parents and their children, both very low (.16 for the PWI, .18 for BMSLSS), and it was not possible to compare factor means. When correlating scores from the 6 single-item scales for parents and children, they were all found to be significant but very low. As regards items from the multiple-item scales for parents and children many correlations are positive and significant, although very low, but others are non significant. The means of some items were substantially higher for children than for parents. For some items, differences were minor, non-significant or even reversed. All of the results suggest that parents’ well-being is very weakly related to their own children’s well-being, in spite of socialization, common material welfare and genetic influences. However, one outstanding result is that in our Catalan sample, parents’ well-being seems to have a greater influence on their female child’s well-being than on their male child’s.     

Evaluation of a novel translational task for assessing emotional biases in different species

Changes in the processing of emotional information are key features of affective disorders. Neuropsychological tests based on emotional faces or words are used to detect emotional/affective biases in humans, but these tests are not applicable to animal species. In the present study, we investigated whether a novel affective tone discrimination task (ATDT), developed to study emotion-related behaviour in rats, could also be used to quantify changes in affective states in humans. To date, the methods used in human neuropsychology have not been applicable to animal experiments. Participants completed a training session in which they learnt to discriminate specific tone frequencies and to correctly respond in order to gain emotionally valenced outcomes, to obtain rewards (money), or to avoid punishment (an aversive sound clip). During a subsequent test session, additional ambiguous probe tones were presented at frequencies intermediate between the reward and avoidance paired tones. At the end of the task, participants completed self-report questionnaires. All participants made more avoidance responses to the most ambiguous tone cues, suggesting a bias towards avoidance of punishment. Individual differences in the degrees of bias observed were correlated with anxiety measures, suggesting the task’s sensitivity to differences in state anxiety within a healthy population. Further studies in clinical populations will be necessary to assess the task’s sensitivity to pathological anxiety states. These data suggest that this affective tone discrimination task provides a novel method to study cognitive affective biases in different species, including humans, and offers a novel assessment to study anxiety.     

Inhibitory Control and Moral Emotions: Relations to Reparation in Early and Middle Childhood

ABSTRACT. This study examined links between inhibitory control, moral emotions (sympathy and guilt), and reparative behavior in an ethnically diverse sample of 4- and 8-year-olds (N = 162). Caregivers reported their children's reparative behavior, inhibitory control, and moral emotions through a questionnaire, and children reported their guilt feelings in response to a series of vignettes depicting moral transgressions. A hypothesized meditation model was tested with inhibitory control relating to reparative behavior through sympathy and guilt. In support of this model, results revealed that high levels of inhibitory control were associated with high levels of reparative behavior through high levels of sympathy and guilt. However, the mediation of inhibitory control to reparation through guilt was significant for 4-year-olds only. Results are discussed in relation to the temperamental, regulatory, and affective-moral precursors of reparative behavior in early and middle childhood.

Reciprocal Relations Between Emotional Self‐Efficacy Beliefs and Ego‐Resiliency Across Time

The present study examined the longitudinal relations of adolescents' self‐reported ego‐resiliency to their emotional self‐efficacy beliefs in expressing positive emotions and in managing negative emotions as they moved into early adulthood. Participants were 239 females and 211 males with a mean age of 17 years (SD = .80) at T1, 19 years (SD = .80) at T2, 21 years (SD = .82) at T3, and 25 years (SD = .80) at T4. A four‐wave cross‐lagged regression model and mediational analyses were used. In a panel structural equation model controlling for the stability of the constructs, reciprocal relationships across time were found between ego‐resiliency and emotional self‐efficacy beliefs related to the expression of positive emotions and to the management of negative emotions. Moreover, the relation between ego‐resiliency assessed at T1 and T3, and ego‐resiliency assessed at T2 and T4, was mediated through emotional self‐efficacy beliefs (at T2 and T3, respectively), and vice versa. The posited conceptual model accounted for a significant portion of variance in ego‐resiliency and has implications for understanding the development of ego‐resiliency.     

Effects of 7.5% CO2-Induced Anxiety on Individual Performance During a Group Computer Combat Game

The inhalation of 7.5% CO₂ has been shown to induce cognitive effects similar to anxiety. Sixteen healthy participants (14 male; mean age 25.6 years) inhaled either a mixture of 7.5% CO₂ gas or air while playing a group combat computer game. Participants reported greater feelings of anxiety and fired fewer bullets when inhaling CO₂ compared with air, indicating CO₂-induced anxiety may improve efficiency without task-related decrements. Being able to induce controlled and measured anxiety in group situations by CO₂ inhalation may be a useful technique when evaluating response to stressful situations, such as combat, in simulators or real-life scenarios.
