Cognitive Load Differentially Impacts Response Control in Girls and Boys with ADHD

Children with attention-deficit hyperactivity disorder (ADHD) consistently show impaired response control, including deficits in response inhibition and increased intrasubject variability (ISV) compared to typically-developing (TD) children. However, significantly less research has examined factors that may influence response control in individuals with ADHD, such as task or participant characteristics. The current study extends the literature by examining the impact of increasing cognitive demands on response control in a large sample of 81children with ADHD (40 girls) and 100 TD children (47 girls), ages 8–12 years. Participants completed a simple Go/No-Go (GNG) task with minimal cognitive demands, and a complex GNG task with increased cognitive load. Results showed that increasing cognitive load differentially impacted response control (commission error rate and tau, an ex-Gaussian measure of ISV) for girls, but not boys, with ADHD compared to same-sex TD children. Specifically, a sexually dimorphic pattern emerged such that boys with ADHD demonstrated higher commission error rate and tau on both the simple and complex GNG tasks as compared to TD boys, whereas girls with ADHD did not differ from TD girls on the simple GNG task, but showed higher commission error rate and tau on the complex GNG task. These findings suggest that task complexity influences response control in children with ADHD in a sexually dimorphic manner. The findings have substantive implications for the pathophysiology of ADHD in boys versus girls with ADHD.     

Identity Conflict or Compatibility: A Comparison of Muslim Minorities in Five European Cities

Drawing on large‐scale comparative surveys across nine sociopolitical contexts, we address the question when and why ethno‐religious and city or national identities of European‐born Muslims are in conflict. We argue that the sociopolitical context makes the difference between identity compatibility or conflict and that conflict arises from perceived discrimination and related negative feelings towards the national majority. Using multigroup structural equation modelling, we examine how Turkish and Moroccan Muslims in five European cities combine their civic membership of the city and country of residence—as common identities shared with the national majority—with distinct ethnic and religious identities. In all sociopolitical contexts, participants combined significant city and national identities with strong ethnic and religious identifications. Yet, identification patterns varied between contexts from conflict (negatively correlated minority and civic identities) over compartmentalization (zero correlations) to compatibility (positive correlations). Muslims who perceived more personal discrimination were more committed to their ethnic and religious identities while simultaneously dis‐identifying from their country and city. Across cities, discrimination experiences and negative majority‐group evaluations explained away identity conflict.     

Connecting the dots between fantasy and reality: The social psychology of our engagement with fictional narrative and its functional value

This essay provides an overview of research and theory on narrative and its important, functional role in human experience, including the ways people use media to interrogate their own beliefs and feelings, and derive social meaning. Thought‐provoking film, television, and books can help us make meaning of our lives and grow in ways that are important for our successful social functioning. Research reviewed here demonstrates that exposure to fiction can increase empathy and social skills and reduce prejudice. Our connection to characters and stories has been studied in various ways as extensions of the self into another, while at the same time bringing the other into the self. Bringing together disparate perspectives, we propose that connecting to story worlds involves a process of “dual empathy”—simultaneously engaging in intense personal processing while also “feeling through” characters, both of which produce benefits. Because the value of entertainment narratives may not always be well understood, we explain how those experiences can be personal, social, and can serve important adaptive functions.     

Multiple‐stimulus preference assessments: a comparison of free‐operant and restricted‐operant formats

We compared free‐operant and restricted‐operant multiple‐stimulus preference assessments with three children diagnosed with mental retardation. The methods produced comparable results, although the free‐operant assessment identified fewer potential reinforcers than the restricted‐operant assessment. The highest‐ and lowest‐ranked stimuli from both methods were subsequently evaluated in a concurrent‐operants reinforcer assessment. All participants engaged in behavior that resulted in access to the highest‐ranked stimuli the majority of the time, thus validating both preference assessment methods as effective in identifying reinforcers.

Evaluation of satiation‐resistant head rocking

The persistent head rocking of a woman diagnosed with profound mental retardation was examined during three separate assessments. First, a functional analysis demonstrated that head rocking was maintained independent of social consequences. Next, an antecedent assessment revealed that exposure to alternative sources of stimulation reduced head rocking, but only when the stimulation was being provided. A third assessment, which consisted of an enriched environment, replicated the findings of the first two assessments. Across all three assessments, head rocking persisted at extremely high rates when alternative stimulation was unavailable and returned to high levels immediately following the removal of alternative sources of stimulation. An environmental enrichment (EE) intervention, which was based on the results of the functional analysis and antecedent assessment, resulted in a 70% reduction in the occurrence of the head rocking. In addition, a social validity assessment revealed that the participant's caregivers rated the EE intervention as both effective and socially acceptable. The particular challenges that satiation‐resistant aberrant behavior presents for behavior analysts are addressed. Specific suggestions for research on intervention strategies for persistent aberrant behavior are also provided. Copyright © 2000 John Wiley & Sons, Ltd.     

The growth and development of an infant mental health program: An integrated perspective

This article details the development of the Infant Mental Health Clinical and Training Program at the University of Colorado School of Medicine from 1976 to the present. The article discusses the clinical sites where the program takes place, which include the Neonatal Intensive Care Unit, outpatient child psychiatry clinic, and day treatment programs. Trainees from several mental health disciplines participate in the program, including predoctoral psychology externs, interns from the Clinical Psychology Internship, residents from the Child Psychiatry Training Program, and postdoctoral research fellows in developmental psychopathology. Recently, the Infant Mental Health Program has also been able to offer its own training positions. The philosophical models of clinical service and training are outlined. The article concludes by looking at future directions and challenges for the Infant Mental Health Program. © 1997 Michigan Association for Infant Mental Health     

Sex differences in estimates of multiple intelligences

This paper reports on two studies, each concerned with sex differences in the estimates of Gardner's ‘seven basic types of intelligence’. In the first study, 180 British adults were asked to estimate their own intelligence on the seven intelligence factors. Only one (mathematical/logical) showed a significant sex difference, with males believing they had higher scores than females. Factor analysis of these seven scales yielded three interpretable higher‐order factors. There was a similar sex difference on only one factor (mathematical/spatial intelligence), which showed males rating themselves higher than females. In the second study, 80 student participants completed the same seven estimates of intelligence, plus a standard sex‐role inventory, in order to separate sex and sex role in the self‐estimation of intelligence. A series of sex×sex‐role ANOVAs showed some effects, particularly for mathematical, musical, and spatial intelligence, but nearly always for sex and not sex role. Results suggest that previous studies which found consistent sex differences in self‐estimates of overall intelligence (‘g’) may have over‐exaggerated the issue as the difference is clearly confined to a limited number of factors of intelligence.

Determining Normal Deviance: Adolescent Drug Use?

This research examines change in lifetime drug use frequency among three drugs, marijuana, alcohol and inhalants, and antisocial behaviors using a cohort longitudinal model. Findings indicate marijuana and alcohol use increases with grade level. Inhalants are the only drugs which use decline with grade level. Focus of the paper is whether the use of these three drugs is a normal part of adolescent development. Using three determinants: associations between drug use and grade and scores on an antisocial behavior scale; and percent of abstainers; the authors determined none of the three drugs represent normal deviance. Data are from 2008 thru the 2014 the Caring Communities Youth Survey (CCYS). The concept of normal deviance is discussed.
