Social Skills Mediate the Association of ADHD and Depression in Preadolescents

Childhood attention-deficit/hyperactivity disorder (ADHD) is a replicated risk factor for depression, but the explanatory factors underlying this association have not been reliably identified. Given that social skills (i.e., cooperation, assertion, responsibility, self-control) are sensitive to early ADHD and predict later depression, we tested whether individual differences in social skills individually and collectively mediated predictions of depressive symptoms from early ADHD symptoms. In an ethnically diverse (50 % non-Caucasian) sample of 232 children with (n = 124) and without ADHD (n = 108) followed prospectively for two years (aged 5–10 at Wave 1; 7–12 at Wave 2), we gathered multi-informant (i.e., parent, teacher) and multi-method (e.g., rating scale, structured interview) assessment of key constructs. Using a multiple mediation framework with bootstrapping and statistical control of sex, Wave 1 depression, Wave 1 oppositional defiant disorder (ODD), Wave 1 anxiety, and Wave 2 ADHD symptoms, an independent mediation effect emerged for parent-rated self-control in the prediction of Wave 2 depression (parent-rated) from Wave 1 ADHD symptoms (combined parent and teacher ratings). Teacher-rated social skills at Wave 1 also collectively mediated this association, with teacher-rated assertion emerging as a unique mediator. We discuss the role of social skills in emergent depression among youth with ADHD and consider implications for prevention and intervention.     

Conditioned taste aversions: From poisons to pain to drugs of abuse

Learning what to eat and what not to eat is fundamental to our well-being, quality of life, and survival. In particular, the acquisition of conditioned taste aversions (CTAs) protects all animals (including humans) against ingesting foods that contain poisons or toxins. Counterintuitively, CTAs can also develop in situations in which we know with absolute certainty that the food did not cause the subsequent aversive systemic effect. Recent nonhuman animal research, analyzing palatability shifts, has indicated that a wider range of stimuli than has been traditionally acknowledged can induce CTAs. This article integrates these new findings with a reappraisal of some known characteristics of CTA and presents a novel conceptual analysis that is broader and more comprehensive than previous accounts of CTA learning.     

Mind-wandering: phenomenology and function as assessed with a novel experience sampling method

Mind-wandering refers to the occurrence of thoughts whose content is both decoupled from stimuli present in the current environment and unrelated to the task being carried out at the moment of their occurrence. The core of this phenomenon is therefore stimulus-independent and task-unrelated thoughts (SITUTs). In the present study, we designed a novel experience sampling method which permitted to isolate SITUTs from other kinds of distractions (i.e., irrelevant interoceptive/exteroceptive sensory perceptions and interfering thoughts related to the appraisal of the current task). In Experiment 1, we examined the impact of SITUTs on the performance of the Sustained Attention to Response Task (SART; a Go/No-Go task). Analyses demonstrated that SITUTs impair SART performance to the same extent as irrelevant sensory perceptions. In Experiment 2, we further examined SITUTs in order to assess the possible functions of mind-wandering. We observed that the content of most of reported SITUTs refers to the anticipation and planning of future events. Furthermore, this “prospective bias” was increased when participants' attention had been oriented toward their personal goals before performing the SART. These data support the view that an important function of mind-wandering relates to the anticipation and planning of the future.     

Social anxiety and the effects of negative self-imagery on emotion, cognition, and post-event processing

Numerous studies have shown that social phobia patients experience negative self-impressions or images during social situations. Clark and Wells (1995) posited that such negative self-images are involved in the maintenance of social phobia. Thus, the present study investigated the effects of negative self-imagery on cognition and emotion during and following a brief social situation. Specifically, high and low socially anxious participants (N = 77) were instructed to hold either a negative or control self-image as they engaged in a brief speech. Participants then rated their anxiety, performance, cognitions, and focus of attention. Twenty-four hours later, they returned to the laboratory and completed questionnaires assessing the amount of post-event processing (PEP) they engaged in. The results showed that, irrespective of the level of social anxiety or depressive symptoms, participants that held the negative self-image experienced higher levels of anxiety, were more self-focused, experienced more negative thoughts, rated their anxiety as more visible, appraised their performance more negatively, and engaged in more negative and less positive PEP than participants that held the control self-image. Collectively the results indicate that negative imagery is causally involved in the maintenance of social phobia, as well as in the generation of social anxiety among non-anxious individuals.     

Interactions between early parenting and a polymorphism of the child's dopamine transporter gene in predicting future child conduct disorder symptoms

Mounting evidence suggests that genetic risks for mental disorders often interact with the social environment, but most studies still ignore environmental moderation of genetic influences. The authors tested interactions between maternal parenting and the variable number tandem repeat (VNTR) polymorphism in the 3' untranslated region of the dopamine transporter gene in the child to increase understanding of gene-environment interactions involving early parenting. Participants were part of a 9-year longitudinal study of 4- to 6-year-old children who met criteria for attention-deficit/hyperactivity disorder (ADHD) and demographically matched controls. Maternal parenting was observed during standard mother-child interactions in Wave 1. The child's conduct disorder (CD) symptoms 5-8 years later were measured using separate structured diagnostic interviews of the mother and youth. Controlling for ADHD symptoms and child disruptive behavior during the mother-child interaction, there was a significant inverse relation between levels of both positive and negative parenting at 4-6 years and the number of later CD symptoms, but primarily among children with 2 copies of the 9-repeat allele of the VNTR. The significant interaction with negative parenting was replicated in parent and youth reports of CD symptoms separately.     

Self-control of feedback during motor learning: accounting for the absolute amount of feedback using a yoked group with self-control over feedback

A traditional control group yoked to a group that self-controls their reception of feedback receives feedback in the same relative and absolute manner. This traditional control group typically does not learn the task as well as the self-control group. Although the groups are matched for the amount of feedback they receive, the information is provided on trials in which the individual may not request feedback if he or she were provided the opportunity. Similarly, individuals may not receive feedback on trials for which it would be a beneficial learning experience. Subsequently, the mismatch between the provision of feedback and the potential learning opportunity leads to a decrement in retention. The present study was designed to examine motor learning for a yoked group with the same absolute amount of feedback, but who could self-control when they received feedback. Increased mental processing of error detection and correction was expected for the participants in the yoked self-control group because of their choice to employ a limited resource in the form of a decreasing amount of feedback opportunities. Participants in the yoked with self-control group committed fewer errors than the self-control group in retention and the traditional yoked group in both the retention and time transfer blocks. The results suggest that the yoked with self-control group was able to produce efficient learning effects and can be a viable control group for further motor learning studies.     

A biopsychosocial formulation of pain communication

We present a detailed framework for understanding the numerous and complicated interactions among psychological and social determinants of pain through examination of the process of pain communication. The focus is on an improved understanding of immediate dyadic transactions during painful events in the context of broader social phenomena. Fine-grain consideration of social transactions during pain leads to an appreciation of sociobehavioral events affecting both suffering persons as well as caregivers. Our examination considers knowledge from a variety of perspectives, including clinical health psychology, social and developmental processes, evolutionary psychology, communication studies, and behavioral neuroscience.     

Identity,Culture and Contestation: Social Identity as Cross-Cultural Theory

In this paper we explore the logic and implications of the social identity approach to group processes. The theory argues that the consequences of social identification for behaviour are not simple givens. Rather than making generalisations about the behaviour that flows from social identification, the theory makes the point that behaviour depends upon the way in which identities are defined. This emphasis upon the contents of social identities draws our attention to their construction and we pay particular attention to how group identities are made and remade in and through argument and social practice. We argue that attention to the dynamics of identity construction means that this perspective is respectful of culture and cultural difference and that the social identity approach therefore has considerable value in exploring the politics and practice of identity wherever group behaviour may be found. Moreover, we argue that the ubiquity of identity-related argument across cultures and contexts reflects the fact that group identity is a basis for social power.     

Deviant Peer Affiliation and Antisocial Behavior: Interaction with Monoamine Oxidase A (MAOA) Genotype

Although genetic and environmental factors are separately implicated in the development of antisocial behavior (ASB), interactive models have emerged relatively recently, particularly those incorporating molecular genetic data. Using a large sample of male Caucasian adolescents and young adults from the National Longitudinal Study of Adolescent Health (Add Health), the association of deviant peer affiliation, the 30-base pair variable number tandem repeat polymorphism in promoter region of the monoamine oxidase-A (MAOA) gene, and their interaction, with antisocial behavior (ASB) was investigated. Weighted analyses accounting for over-sampling and clustering within schools as well as controlling for age and wave suggested that deviant peer affiliation and MAOA genotype were each significantly associated with levels of overt ASB across a 6-year period. Only deviant peer affiliation was significantly related to covert ASB, however. Additionally, there was evidence suggestive of a gene-environment interaction (G × E) where the influence of deviant peer affiliation on overt ASB was significantly stronger among individuals with the high-activity MAOA genotype than the low-activity genotype. MAOA was not significantly associated with deviant peer affiliation, thus strengthening the inference of G × E rather than gene-environment correlation (rGE). Different forms of gene-environment interplay and implications for future research on ASB are discussed.     

Objectification leads to depersonalization: The denial of mind and moral concern to objectified others

Philosophers have argued that when people are objectified they are treated as if they lack the mental states and moral status associated with personhood. These aspects of objectification have been neglected by psychologists. This research investigates the role of depersonalization in objectification. In Study 1, objectified women were attributed less mind and were accorded lesser moral status than non‐objectified women. In Study 2, we replicated this effect with male and female targets and extended it to include perceptions of competence and pain attribution. Further, we explored whether target and perceiver gender qualify depersonalization. Overall, this research indicates that when people are objectified they are denied personhood.
