An Ecological Approach to Enhancing Parenting Skills in Family Therapy

To increase the effectiveness of parent education interventions, family therapists can address those factors that shape the way in which parents interact with their children. This article presents ecological theory as a framework that can help clinicians expand the range of their parent training efforts. In order to assess the utility of ecological theory for clinical practice, the present study empirically explored the ways in which selected characteristics of parents, children, and the family context related to mothers' parenting behavior. Specific recommendations for family therapists who employ parent training techniques are offered.     

Descartes on the Identity of Passion and Action

According to the standard Aristotelian doctrine of the identity of passion and action (I_pa), a passion and the action with which it is identified are distinguished through a distinction of reason, and both passion and action are located in the patient. Descartes has recently been interpreted by some scholars to be rejecting I_pa in favor of a view that throws into contention a dualistic interpretation of his philosophy of mind. This article contends that Descartes did hold I_pa, albeit expressed in his own metaphysical vocabulary of substance and mode. On this interpretation, (1) a passion and the action with which it is identified are distinguished through a conceptual distinction or distinction of reason and (2) the passion and the action constitute one and the same mode which is locatedin the patient. This result is significant first, because it shows Descartes's retention of a fundamentally Aristotelian understanding of the metaphysical categories of passion and action and second, because it removes some of the support for recent interpretations on which Descartes is seen in the Passions of the Soul to diverge from a dualistic view of mind and body.     

Interference with spatial working memory: An eye movement is more than a shift of attention

In the present experiments, we examined whether shifts of attention selectively interfere with the maintenance of both verbal and spatial information in working memory and whether the interference produced by eye movements is due to the attention shifts that accompany them. In Experiment 1, subjects performed either a spatial or a verbal working memory task, along with a secondary task requiring fixation or a secondary task requiring shifts of attention. The results indicated that attention shifts interfered with spatial, butnot with verbal, working memory, suggesting that the interference is specific to processes within the visuospatial sketchpad. In Experiment 2, subjects performed a primary spatial working memory task, along with a secondary task requiring fixation, an eye movement, or an attention shift executed in the absence of an eye movement. The results indicated that both eye movements and attention shifts interfered with spatial working memory. Eye movements interfered to a much greater extent than shifts of attention, however, suggesting that eye movements may contribute a unique source of interference, over and above the interference produced by the attention shifts that accompany them.     

Affect Dysregulation in Individuals With Borderline Personality Disorder: Persistence and Interpersonal Triggers

We hypothesized that affect dysregulation among individuals with borderline personality disorder (BPD) would involve greater persistence of negative affect between interpersonal events and heightened reactivity to stimuli indicating risk of rejection or disapproval, specifically perceptions of others’ communal (agreeable-quarrelsome) behaviors. A total of 38 participants with BPD and 31 controls collected information about affect and perceptions of the interaction partner's behavior during interpersonal events for a 20-day period. Negative and positive affect persisted more across interpersonal events for individuals with BPD than for controls. In addition, individuals with BPD reported a greater increase in negative affect when they perceived less communal behavior and a smaller increase in positive affect when they perceived more communal behavior in others. Findings indicate the importance of interpersonal perceptions in the affect dysregulation of individuals with BPD.     

Arousal interventions for athletic performance: Influence of mental preparation and competitive experience

Abstract

Mental preparation, or “psych-up” strategies have been assumed to promote physical arousal which subsequently improves certain athletic performances. The present experiment examined the role of arousal changes in the use of psych-up strategies on a physical strength task and a reaction time-decision task for subjects varying in competitive experience. Eighty-four subjects were reliably divided into high, moderate, or low competitive experience groups and randomly assigned to one of three mental preparation strategies. These strageies, which the subjects employed during a mental preparation period for both tasks, were either: (a) a self-generated arousal strategy, (b) a prescribed arousal strategy, or (c) a placebo-control strategy. While heart rate was being monitored, each subject completed a baseline trial, then one trial following a 45 sec mental preparation period and one trial following a 45 sec distraction interval. Order of presentation of tasks and order of presentation of distraction and mental preparation trials were counterbalanced and statistically analyzed. The results support the utility of different mental preparation strategies for increasing strength performance, but not reaction time-decision performance, for subjects with moderate and high levels of previous competitive experience. Self-generated arousal strategies enhanced performance of moderate experienced subjects. Analyses of the heart rate data failed to support the assumption that physiological arousal mediates the influence of psych-up strategies. Mental preparation strategies improved athletes' performance on certain tasks, however these strategies do not necessarily achieve their effects through increased autonomic arousal.     

Association of <Emphasis Type="Italic">ADAM10</Emphasis> and <Emphasis Type="Italic">CAMK2A</Emphasis> Polymorphisms with Conduct Disorder: Evidence from Family-Based Studies

Twin and family studies have shown that genetic factors play a role in the development of conduct disorder (CD). The purpose of this study was to identify genetic variants associated with CD using a family-based association study. We used 4,720 single nucleotide polymorphisms (SNPs) from the Illumina Panel and 11,120 SNPs from the Affymetrix 10K GeneChips genotyped in 155 Caucasian nuclear families from Genetic Analysis Workshop (GAW) 14, a subset from the Collaborative Study on the Genetics of Alcoholism (COGA). 20 SNPs had suggestive associations with CD (p < 10⁻³), nine of which were located in known genes, including ADAM10 (rs383902, p = 0.00036) and CAMK2A (rs2053053, p = 0.00098). Our results were verified using the International Multi-Center ADHD Genetics Project (IMAGE) dataset. In conclusion, we identified several loci associated with CD. Especially, the two genes (ADAM10 and CAMK2A) have been reported to be associated with Alzheimer’s disease, bipolar disorder and depression. These findings may serve as a resource for replication in other populations.     

Social validity: Perceptions of check and connect with early literacy support

This article underscores the potential advantages of qualitative methods to illustrate the depth and complexity of social validity. This investigation evaluates the social validity of Check and Connect with Early Literacy Support (CCEL), through the perspectives of teachers and caregivers whose children participated in the intervention. Teachers from six classrooms and caregivers from six families participated in evaluating the social validity of this intervention using a combination of qualitative and quantitative methods. Participants completed the Treatment Acceptability Rating Scale—Revised (TARF-R; Reimers, T. M., Wacker, D. P., Cooper, L. J. & DeRaad, A. O. (1992). Clinical evaluation of the variables associated with treatment acceptability and their relation to compliance. Behavioral Disorders, 18(1), 67-76.), a quantitative measure of treatment acceptability (a component of social validity), and were interviewed using qualitative interviews and focus groups. Results were analyzed through ethnographic methodology and indicate complex, reciprocal relationships among factors related to social validity. This investigation is considered in light of recent efforts to develop a systematic approach to evaluate the adequacy of intervention research using qualitative methods.     

Loss and persistence of implicit memory for sound: Evidence from auditory stream segregation context effects

An important question is the extent to which declines in memory over time are due to passive loss or active interference from other stimuli. The purpose of the present study was to determine the extent to which implicit memory effects in the perceptual organization of sound sequences are subject to loss and interference. Toward this aim, we took advantage of two recently discovered context effects in the perceptual judgments of sound patterns, one that depends on stimulus features of previous sounds and one that depends on the previous perceptual organization of these sounds. The experiments measured how listeners’ perceptual organization of a tone sequence (test) was influenced by the frequency separation, or the perceptual organization, of the two preceding sequences (context1 and context2). The results demonstrated clear evidence for loss of context effects over time but little evidence for interference. However, they also revealed that context effects can be surprisingly persistent. The robust effects of loss, followed by persistence, were similar for the two types of context effects. We discuss whether the same auditory memories might contain information about basic stimulus features of sounds (i.e., frequency separation), as well as the perceptual organization of these sounds.     

The adrenergic receptor α-2A gene (ADRA2A) and neuropsychological executive functions as putative endophenotypes for childhood ADHD

There is resurgent interest in the psychiatric literature in endophenotypes, variables thought to more strongly reflect the effects of candidate genes than do manifest disorders. In a sample of 176 children with attention deficit hyperactivity disorder (ADHD) and 52 of their siblings, we examined the validity of several putative endophenotypes for ADHD that represent commonly used clinical measures of multiple cognitive/neuropsychological domains of executive functions (EFs). We review their distributional normality, their relations to ADHD symptoms in probands and unaffected siblings relative to nonADHD controls, and their correlation in siblings. We also tested the EF measures’ associations with the ADRA2A gene and whether they mediated or moderated the associations between ADHD and ADRA2A. Several EF measures showed association with ADRA2A, as well as moderation, but not mediation, of its association with ADHD. Implications of the results for evaluating the validity and utility of putative endophenotype measures and for finding candidate gene effects on ADHD are discussed.
