Executive Functioning, Temporal Discounting, and Sense of Time in Adolescents with Attention Deficit Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD)

Clinic-referred teens (ages 12–19) with ADHD and ODD (N = 101) were compared to community control (CC) teens, equated for age and sex, (N = 39) on a variety of psychological tasks assessing executive functioning (EF), temporal reward discounting, and time estimation and reproduction. A factor analysis reduced the EF measures to three dimensions, representing CPT Inattention, Working Memory, and CPT Inhibition. Results indicated that the ADHD group had significantly more CPT Inattention than the CC group. No differences were found for Working Memory or CPT Inhibition. The ADHD group displayed significantly greater temporal discounting of delayed hypothetical monetary rewards relative to immediate ones and manifested more impaired time reproduction, but not time estimation, than did the CC group. Main effects for level of IQ were found only on the Working Memory factor and largely did not interact with the group factor otherwise. The group differences in CPT Inattention, temporal discounting, and time reproduction were not a function of level of comorbid oppositional defiant disorder, delinquency, or anxiety–depression. Results are reasonably consistent with past research on EF and sense of time in children with ADHD and extend these findings to the adolescent age group. Problems with working memory and CPT inhibition found in prior studies of children with ADHD, however, were not evident here, perhaps owing to age-related improvements or insufficient task difficulty.     

Affect Regulation and Attachment Strategies of Adjudicated and Non-Adjudicated Adolescents and Their Parents

This exploratory qualitative study used semi-structured interviews with adjudicated and non-adjudicated adolescents and their parents to identify: (1) different behavioral manifestations of affect regulation and attachment interactions as described by respondents; and (2) interactional patterns that we might wish to target in a therapeutic intervention. Parents used more functional internal affect regulation strategies, while adolescents relied on less functional ones. Most respondents used functional external affect regulation strategies, such as direct communication. Approximately half of them used more dysfunctional strategies, such as yelling and aggression. Most of the adolescents used at least one secure attachment strategy in their relationships with their parents, but the majority also used avoidant or ambivalent strategies. Almost half of the parents described secure strategies in their relationships with their adolescents, while the remainder indicated using insecure.     

Dominance and age-related changes in the play fighting of intact and post-weaning castrated male rats (Rattus norvegicus)

The play fighting behaviour of male rats (Rattus norvegicus) castrated at weaning was compared to that of intact controls during the juvenile and post-pubertal phases of development. Following puberty, both the castrated and intact animals exhibited an age-related change in their play fighting; the frequency of initiating play fighting decreased and juvenile patterns of playful defense were replaced by more adult-like patterns. As these changes occurred even in the absence of the pubertal surge of gonadal hormones, they were more likely to result from the organizational effects of gonadal hormones in the perinatal period than the activational effects of these hormones at puberty. Although the castrated animals exhibited the age-related changes in behaviour, they did not exhibit the asymmetries in play associated with dominance relationships. As demonstrated in previous studies, in pairs of intact rats, the animal that attacks the most and uses more juvenile defenses during play fighting and weighs the least is typically the subordinate. In the castrates, asymmetries in weight and playful defense are not related to play frequency, indicating the absence of a dominance relationship. Although the characteristic changes in male play fighting at puberty are independent of the activational effects of gonadal hormones, dominance relationships and their associated changes in play fighting are dependent on these hormones. Therefore, in the perinatal period gonadal hormones most likely organize the age-related changes in play behaviour, whereas post-pubertally gonadal hormones activate dominance relationships and thus, indirectly modify play fighting by affecting dominance-associated assymetries in behaviour. © 1996 Wiley-Liss, Inc.     

Goodness-of-fit in family context: Infant temperament, marital quality, and early coparenting behavior

This study examined the contributions of infant temperament and marital relationship quality to the quality of the early coparenting relationship for couples parenting 3.5-month-old infants. Marital quality was assessed observationally during the third trimester of pregnancy. When infants were 3.5 months old, infant temperamental characteristics (fussiness and unadaptability) were rated by parents and observers and coparenting behavior was assessed observationally in play and child care contexts. Results indicated that associations between infant temperament and coparenting behavior depended on marital quality: couples with high marital quality showed more optimal coparenting behavior when faced with a challenging infant, whereas couples with low marital quality showed less optimal coparenting behavior when caring for a challenging infant.     

Childhood physical and sexual abuse in depressed patients with single and multiple suicide attempts

Research has shown both childhood physical and sexual abuse to be associated with later suicide attempts, although some studies have not supported these findings. However, few studies have investigated differences in physical and sexual abuse histories among single and multiple suicide attempters. The goals of the current study were two-fold: (a) to replicate previous findings of associations between childhood sexual and physical abuse and suicide attempts, and (b) to explore differences in reports of childhood physical and sexual abuse among single and multiple suicide attempters. While our results supported the findings that individuals with a history of suicide attempts are more likely to report histories of childhood physical and sexual abuse, we did not find a difference in reported abuse between single and multiple suicide attempters. Implications of these findings, as well as implications for future research, are discussed.     

Estimating the effects of misleading information on witness accuracy: can experts tell jurors something they don't already know?

This study investigated potential differences between expert and lay knowledge of factors influencing witness suggestibility. Expert psychologists (N = 58), jurors (N = 157), and jury‐eligible undergraduates (N = 220) estimated the effects of misleading information on witness accuracy for three age groups in various conditions. Respondents possessed similar knowledge of age‐related trends in suggestibility, the positive effects of a pre‐misinformation warning, and the negative influence of longer delays between the event/misinformation and event/final memory test. Compared to experts, laypeople underestimated the size of suggestibility differences between age groups and lacked knowledge about how event detail centrality, witness participation, and source prestige can increase witness suggestibility. Laypeople rated themselves as being largely unfamiliar with witness suggestibility research and thought that expert testimony would be beneficial. These data shed light on the potential helpfulness of expert testimony in cases involving witness suggestibility. Copyright © 2006 John Wiley & Sons, Ltd.     

Understanding multiple dimensions of compensation satisfaction

We conducted meta-analyses of multiple dimensions of compensation satisfaction. An examination of 213 samples from 182 studies yielded several interesting findings of importance to practice and future research. We examined the relationships among four dimensions of compensation satisfaction (pay level, pay raises, benefit level, pay structure and administration satisfaction), and found that the three dimensions related to direct pay are highly related to one another. The relationships between benefits and the three direct pay dimensions were modest. We also analyzed antecedents, correlates, and consequences of the four compensation satisfaction dimensions. The antecedents of pay raise satisfaction have received the most attention, and our results indicate that both perceptual (e.g., perceptions of the basis for a pay raise) and objective (i.e., the amount of the pay raise) antecedents play roles in determining pay raise satisfaction. Previous research on the relationship between employee costs for benefits and benefit satisfaction have been inconclusive. The meta-analysis yields a modest, negative relationship between employee costs and benefit satisfaction. Additional results provide the foundation for our discussion of the current state of research in these areas, recommendations for practice, and suggestions for future research.     

Genetics, Dementia, and the Elderly

ABSTRACT— Whether or not an individual develops dementia is powerfully influenced by genes. For Alzheimer's disease, the most common type of dementia, one susceptibility gene with major effects has been identified, but progress finding other susceptibility genes has stalled. Twin studies have revealed that nongenetic risk also plays an important role, as there are many monozygotic twin pairs in which only one individual has dementia. Scientists have argued that gene-by-environment interactions will be key to understanding vulnerability to Alzheimer's disease; but to date, few substantial gene-by-environment interactions have been replicated. Often, too, the nongenetic or lifestyle factor appears to have a protective effect only for those individuals not carrying the risky version of the gene, not for those individuals who are at genetic risk.     

Money: a therapeutic tool for couples therapy

This article addresses the therapeutic importance of discussing money at every stage of a couple's relationship, both as a concrete reality and as a metaphor for security, adequacy, competence, commitment, acceptance, and acknowledgment in a relationship. I will present a developmental schema looking at financial issues that couples confront at various stages in the adult life cycle and how these affect and reflect relationship problems. The article also presents a money questionnaire as a useful tool for exploring family-of-origin financial history, affect, and behavior.
