The heterogeneity of attention‐deficit/hyperactivity disorder symptoms and conduct problems: Cognitive inhibition,emotion regulation,emotionality, and disorganized attachment

This study examined the contributions of several important domains of functioning to attention‐deficit/hyperactivity disorder (ADHD) symptoms and conduct problems. Specifically, we investigated whether cognitive inhibition, emotion regulation, emotionality, and disorganized attachment made independent and specific contributions to these externalizing behaviour problems from a multiple pathways perspective. The study included laboratory measures of cognitive inhibition and disorganized attachment in 184 typically developing children (M age = 6 years, 10 months, SD = 1.7). Parental ratings provided measures of emotion regulation, emotionality, and externalizing behaviour problems. Results revealed that cognitive inhibition, regulation of positive emotion, and positive emotionality were independently and specifically related to ADHD symptoms. Disorganized attachment and negative emotionality formed independent and specific relations to conduct problems. Our findings support the multiple pathways perspective on ADHD, with poor regulation of positive emotion and high positive emotionality making distinct contributions to ADHD symptoms. More specifically, our results support the proposal of a temperamentally based pathway to ADHD symptoms. The findings also indicate that disorganized attachment and negative emotionality constitute pathways specific to conduct problems rather than to ADHD symptoms.     

Keeping the Peace—Police Behaviour at a Mass Event

This study examined the collective behaviour of the police during a football match at the 2006 Football World Cup. What peacekeeping and aggravating processes could be identified and what were their consequences? Data were collected using observation and field interviews. Some critical situations could have escalated into riots; however, the police showed trust in the majority of the supporters' intentions to be peaceful. Distrust was reserved for selected individuals who were under surveillance. This, together with tactics involving using different forces for different tasks and an overall organisational strategy focusing on the festivity of the event, was the main reason for the peaceful outcome. A friendly but firm approach was successful in keeping the peace. Copyright © 2012 John Wiley & Sons, Ltd.     

Individual differences in 10‐month‐olds' performance on the A‐not‐B task

This study used the classical A‐not‐B task (Piaget, 1954 ) to explore individual differences in cognitive flexibility in 10‐month‐old infants by: (1) examining how differences in search performance during A trials relate to search performance during B trials; (2) studying the relation between temperamental dimensions and A‐not‐B performance; and (3) investigating differences in search performance between looking and reaching responses within the same task. Forty infants were tested on a fixed‐design‐version of the A‐not‐B task, not allowing for training or individual adjustment, but instead eliciting additional search behaviors than the common correct responses in A trials and perseverative errors in B trials. Infants were also rated by their parents on the temperamental scales Activity level and Attention span. The main findings were: (1) performance on A trials affected B trial performance, with infants being more correct on A trials having more incorrect and less ‘no search’ responses on B trials; (2) activity level, but not attention span, was related to performance on the A‐not‐B task, with infants performing better on A trials having a lower activity level; and (3) there were a few differences in performance with regard to modality, indicating that responding correctly by looking may be less cognitively demanding than doing so by reaching. This study demonstrated that 10‐month‐olds show a wide variation of search behaviors on this A‐not‐B task, resulting in individual differences in performance. These differences are suggested to reflect variation in temperamental activity level as well as maturity of short term/working memory, inhibition and cognitive flexibility.     

The role of sustained attention,maternal sensitivity,and infant temperament in the development of early self-regulation

This study investigated infant predictors of early cognitive and emotional self-regulation from an intrinsic and caregiving environmental perspective. Sustained attention, reactive aspects of infant temperament, and maternal sensitivity were assessed at 10 months (n = 124) and early self-regulation (including executive functions, EF, and emotion regulation) was assessed at 18 months. The results indicated that sustained attention predicted early EF, which provide empirical support for the hierarchical framework of EF development, advocating early attention as a foundation for the development of cognitive self-regulation. Maternal sensitivity and surgency predicted emotion regulation, in that infants of sensitive mothers showed more regulatory behaviours and a longer latency to distress, whereas high levels of surgency predicted low emotion regulation, suggesting both the caregiving environment and temperament as important in the development of self-regulation. Interaction effects suggested high sustained attention to be a protective factor for children of insensitive mothers, in relation to emotion regulation. In addition, high levels of maternal sensitivity seemed to foster development of emotion regulation among children with low to medium levels of sustained attention and/or surgency. In all, our findings point to the importance of both intrinsic and extrinsic factors in infant development of self-regulation.     

Creativity and the subliminal manipulation of projected self‐images

Abstract:

This is a report of two experiments on the relationship between creativity and the effects of manipulations of self‐image. Creativity was estimated with the Creative Functioning Test (CFT), an assessment of the tendency to bar the use of subjective interpretations when the support for a “correct” interpretation is being gradually eroded. Self‐image was manipulated in the Identification Test (IT). This involves a backwards masking design in which an ambiguous picture of a face is presented briefly on a viewing screen, preceded by either of two subliminal verbal messages. These were I SUPERIOR and I INFERIOR in a pilot study (n = 25) and I GOOD and I BAD in the main study (n = 33). In the latter, there was also an interview which served to further cross‐validate the CFT. In both studies, creative subjects alternated between reporting young faces and adult ones significantly more often than uncreative subjects. Their identity was not, then, fixedly adult. Creative and uncreative subjects also defended their projected self‐image in different ways against the subliminal manipulations. High and stable self‐confidence was typical of both highly creative and uncreative subjects, but not of subjects in the middle range. Still, the self‐confidence in the two extreme groups was only superficially similar.     

EDITORIAL

The aim of the present study was to evaluate the usefulness of Barkley’s (1997a) model of inhibition and executive functioning in describing the deficits associated with Attention Deficit Hyperactivity Disorder (ADHD). Besides group differences, the present study addressed the question of independent effects of inhibition and the other executive functions in discriminating between children with ADHD and controls and how well, in terms of sensitivity and specificity, these measures can classify the children into the correct group. The results showed that children with ADHD differed significantly from controls with regard to measures of inhibition as well as all other executive function measures, except repetition of hand movements. In logistic regression models, three different measures tapping inhibition, working memory and emotion regulation were shown to be significant independent predictors of group membership. The sensitivity for these three variables as a set was 76.2, the specificity was 90.5, with a total of 86% of the sample correctly classified. When excluding the parental rating of emotion regulation, the overall classification rate decreased some, but was still relatively high in comparison with previous studies within this area of research.     

Effects of alcohol and marijuana on dynamic visual acuity: I. Threshold measurements

Alcohol and marijuana produce significant dose-related reductions in dynamic visual acuity. Ten subjects participated in a double-blind experiment involving three dose levels of each drug (including placebo). The reduction of DVA produced by alcohol (1.0 ml 95% ethanol/kg body weight) was greater than for marijuana (15 mg Δ-9-tetrahydrocannabinol), and we suggest that this difference was produced by differential oculomotor effects of the two drugs. We have speculated that reduction in DVA under alcohol may be a contributing factor in alcohol-related traffic accidents.     

Reflecting talks: a pedagogical model in the learning organization

The aim of the article is to deepen the understanding of how a pedagogical model for reflecting talks can be used in order to make sustainable learning part of the daily work in the learning organization. From an interactive research approach, we have together with a project management group in a European Social Fund project worked with sustainable learning and knowledge development. Empirical data has been collected at the implementation of ten reflecting talks about sustainable equality. The results of the study lead to a strategy for how sustainable learning can become part of the daily work at a workplace. The strategy is constituted by a pedagogical model for reflecting talks, which clearly shows how sustainable learning in an organization can be structured. The core of the pedagogical model for the reflecting talks where both practically applied and theoretically anchored knowledge are important components. The learning process is based on observation, reflection, analysis and discussion of concrete situations/events. The models rests on four basic conditions; pedagogical competence, a delimited problem area, the learning group and timeframes. The model can be used in the daily work at short dialogues or at more penetrating discussions.
