Conners’ continuous performance test (CCPT-II) in children with ADHD,ODD, or a combined ADHD/ODD diagnosis

The current study investigated if results on the Conners’ Continuous Performance Test (CCPT-II) could discriminate between children with ADHD (n = 59), ODD (n = 10), ADHD+ODD (n = 15), and normal controls (n =160), and how the results are associated with and explained by the intellectual function of the child. The sample was derived from the Bergen Child Study (BCS), a longitudinal, ongoing, population-based study of children’s development and mental health. CCPT-II performance did not differentiate between the three diagnostic groups (i.e., ADHD, ODD, and ADHD+ODD). Children with ODD (with or without comorbid ADHD) did not differ from children in the control group on any CCPT-II parameters. Children with ADHD made statistically significant more errors of omissions and showed a more variable response time to targets than the control group. The correlations between CCPT-II measures and IQ were mild to moderate, and there was a statistically significant group difference in IQ: Children with ADHD, and children with ADHD+ODD, obtained lower IQ scores than normal controls. A hierarchical multiple regression analysis showed that IQ, but not diagnostic group status, was significant predictors of CCPT-II performance. CCPT-II performance should be interpreted with caution when assessing ADHD and/or ODD in children.     

Stability of young children's attachment representations: Influence of children's and caregiver's characteristics

This research explores the stability of attachment representations, assessed by the Attachment Story Completion Task, within early childhood. Hypotheses were also formed about the influence of parenting, externalizing behavior and intelligence quotient (IQ) on the developmental course of children's attachment representations. Data were collected from 358 French-speaking Belgian children. Security and disorganization showed a linear improvement with age. The effect of time on the two growth curves was influenced by the child's externalizing behavior. When language abilities were controlled for in a subsample of referred children for externalizing behavior, the growth in security was found to be influenced by reasoning IQ, but the effects for disorganization were unchanged. The implications of the results for both research and clinical purposes are discussed.     

Infrastructure and Scaffolding: Interpretation and Change of Research Involving Human Genetic Information

This essay addresses the relationship of interpretation to change, at two levels. One level concerns the revolutionary claims of molecular biology and biotechnology about using genetic information, read literally or with a minimum of interpretation, to reshape human life. The other level concerns the relationship in social studies of science and technology (STS) between interpreting projects in the life sciences and influencing their direction. On that level, the essay is experimental, employing a series of vignettes that introduce themes and questions—scaffolding—intended to stimulate readers to make their own connections between interpretation and change, in science, STS, and society. The vignettes in Part 1, which range from treatment of individuals with PKU or MAOA genes to personalized medicine and biobanks, indicate in different ways that the use of genetic information always requires social infrastructure. Once attention is given to the actual or implied social infrastructure, the prospect of reshaping life using human genetic information raises more questions than it answers. This thread carries over into Part 2, which speaks to an area of STS that needs more development, namely, conceptualizing the structure of the social context of scientific and technological developments and the nature of human agency in the ongoing restructuring of that context. The vignettes create a picture in which the influence on science of an STS interpretation will, like any effort to produce change, depend on how it links with other engagements and with the heterogeneous components that make up ongoing, intersecting processes of science in society.     

Response expectancy versus response hope in predicting birth‐related emotional distress and pain

Response expectancies and response hopes have been shown to be two distinct constructs with important implications for nonvolitional outcomes. More specifically, studies show that response expectancies: (1) are sufficient to cause nonvolitional outcomes, (2) are not mediated by other psychological variables, and (3) are self‐confirming while seemingly automatic. A new programmatic research line has differentiated between people's response expectancies and their response hopes regarding nonvolitional outcomes and showed that even if response hope and response expectancy are separate constructs, they are not unrelated. These concepts have not yet been studied in pregnant women. Moreover, determining the causal factors that best explain the variance of emotional distress and pain in pregnancy is of great importance. Thus, the aim of this study was to investigate the interrelations between response expectancy and response hope in pregnant women with respect to (1) emotional distress prior to giving birth and (2) pain during giving birth. Additionally, self‐reported labor hours were analyzed as a secondary outcome. Results show that response expectancy for pain directly predicts pain, and that the discrepancy between response hopes and response expectancies is a strong predictor of investigated outcomes. Thus, our results support the idea that preventive psychological interventions for pregnant women should emphasize adjusting response expectancies and response hopes regarding the pain and emotional distress associated with giving birth. We believe that the results have both theoretical and practical implications and the topic deserves further investigation.     

Reconsidering illness-related goals: Is discrepancy resolved by confronting emotions?

The aim of this study was to examine prospectively whether patients with an illness imposing self-management demands (29 asthma patients and 23 diabetic patients) would adjust their evaluations of discrepant illness-related goals. Goals were considered discrepant when patients rated them as important but less attainable, or as less important but attainable. We hypothesized that discrepancy would be resolved by adjusting attainability evaluations and that shifts in these evaluations would be more present in important but less attainable goals. We also hypothesized that shifts in evaluations of discrepant goals would be promoted by engaging in confronting emotions associated with the goal as a first step in coming to terms with discrepant goals. Results confirmed the first, but not the second hypothesis as confronting emotions proved to increase discrepancy evaluations of illness-related goals. These findings are discussed with an emphasis on confronting emotions as a strategy for coming to terms with the experience of discrepancy.     

When Being Discrepant from One's Ideal or Ought Selves Hurts: The Moderating Role of Neuroticism

Self‐discrepancy theory posits that people experience emotional consequences when they perceive discrepancies between their actual and possible selves. However, the extent to which people react emotionally to these self‐discrepancies (i.e. ideal, ought and undesired) may be a function of individual differences in neuroticism. Across both experimental (Study 1; N = 155) and correlational designs (Study 2; N = 139) involving college students, the authors demonstrated that neuroticism moderated the discrepancy–emotion associations such that high‐neuroticism individuals showed elevated depression and anxiety symptoms when their self‐discrepancies were activated. The heightened symptoms were maintained over time. Negative repetitive thoughts (i.e. rumination and worry) were examined as potential mediating mechanisms between the discrepancy × neuroticism interaction and symptoms. Partial support was obtained in that rumination mediated between undesired discrepancy × neuroticism interaction and anxious/depressive symptoms. Implications and possible theoretical extensions for self‐discrepancy theory are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Impulsive Responses In Children with Conduct Disorder and Borderline Intellectual Functioning

The study is designed to investigate response inhibition in children with conduct disorder and borderline intellectual functioning. To this end, children are compared to a normal peer control group using the Alertness test. The test has two conditions. In one condition, children are instructed to push a response button after a visual “go” signal is presented on the screen. In a second condition the “go” signal is preceded by an auditory signal, telling the child that a target stimulus will occur soon. Compared to the control group, the group carrying the dual diagnosis made many preliminary responses (responses before the presentation of the “go” signal), especially in the condition with an auditory signal. This impulsive response style was controlled for attention deficit/hyperactivity disorder characteristics of the children.     

Postnatal exposure to methyl mercury and neuropsychological development in 7-year-old urban inner-city children exposed to lead in the United States

Background: The most common route for general population exposure to methyl mercury (MeHg) is fish consumption. Recommendations to pregnant women about consuming fish contaminated with MeHg are also applied to children, but there are few studies available about the effects of low-level postnatal MeHg exposure in them.

Objectives: To investigate the association between postnatal methyl mercury exposure and neuropsychological development in a study of children also exposed to lead, both measured at 7 years.

Methods: We measured MeHg concentrations in blood samples from the Treatment of Lead-Exposed Children (TLC) trial in which 780 children with elevated concentrations of lead in blood were followed with neuropsychological tests from ages 12–33 months through 7 years. Here we examine blood MeHg concentration and neuropsychological test scores, both measured at age 7 years. We used a maximum likelihood method to estimate geometric mean MeHg concentration and generalized linear regression models to analyze MeHg and neuropsychological test scores.

Results: Geometric mean MeHg concentration was 0.56 (95% confidence interval: 0.52, 0.59) μg/L. A 1 μg/L increase in MeHg was associated with a 2.1 (95% confidence interval: 0.4, 3.8) point increase in Full-Scale IQ and 0.2 (95% confidence interval: 0.02, 0.4) point increase in Learning Slopeindex T-score on a test of verbal memory.

Conclusions: Our results suggest that the relatively low MeHg exposure in US school-aged children from this population has no detectable adverse effect on neuropsychological development. The positive associations observed between MeHg and neurodevelopment may indirectly reflect consumption of beneficial polyunsaturated fatty acids from seafood.     

Antecedents and consequences to perceived career goal–progress discrepancies

Informed by a goal setting and self-regulation perspective, we tested a model of perceived career goal–progress discrepancies (i.e., perception of progress made towards achieving career goals relative to where one should be if the goals were to be attained), which proposed that negative feedback from significant others predicts career goal–progress discrepancies, which, in turn, predicts levels of career-related distress. The model also proposes that active feedback seeking strengthens the relationship between feedback from significant others and goal–progress discrepancies, and that career self-regulatory behaviours (career exploration and planning) weaken the relationship between career goal–progress discrepancies and career distress. Using a sample of 420 young adults (mean age = 20.3 years, 73% female), we found that feedback from significant others was related to both career goal–progress discrepancies and career distress, career goal–progress discrepancies were related to career distress, and goal–progress discrepancies partially mediated between feedback from significant others and career distress. Supporting the moderated effects, goal–progress discrepancies were higher at higher levels of negative feedback for those more actively seeking feedback, and career distress was lower at lower levels of discrepancy for those more engaged in exploration and planning.     

Corporal Punishment by Mothers and Development of Children's Cognitive Ability: A Longitudinal Study of Two Nationally Representative Age Cohorts

This study tested the hypothesis that the use of corporal punishment (CP), such as slapping a child's hand or “spanking,” is associated with restricted development of cognitive ability. Cognitive ability was measured at the start of the study and 4 years later for 806 children age 2–4 and 704 children age 5–9 in the National Longitudinal Study of Youth. The analyses controlled for 10 parenting and demographic variables. Children of mothers in both cohorts who used little or no CP at Time 1 gained cognitive ability faster than children who were not spanked. The more CP experienced, the more they fell behind children who were not spanked.
