Attentional disregulation: a benefit for implicit memory

The authors investigated the effect of age and time of testing on the ability to control attention and addressed the possibility that older adults' susceptibility to distraction may sometimes facilitate performance on a later cognitive task. Using a modification of a G. Rees, C. Russell, C. D. Frith, and J. Driver (1999) procedure, the authors asked the participants to make same or different judgments on line drawings superimposed with task-irrelevant letter strings. Memory for the distractors was subsequently tested with an implicit memory task. Both older and young adults demonstrated greater memory for distractors at nonoptimal times of day than at optimal times of day; however, older adults showed considerably better memory for the distractors than did young adults.     

Links Between Antisocial Behavior and Depressed Mood: The Role of Life Events and Attributional Style

Comorbidity between antisocial behavior and depression in adolescence is widely recognized. This paper examines whether links with depressed mood differ among three subtypes of antisocial behavior: oppositionality, physical aggression and delinquency. In addition we examine two possible contributors to these links: negative life events that are dependent upon the individual's actions and depressogenic attributional style. Data are drawn from the G1219 large-scale community twin and sibling sample, and include 2409 questionnaire responses from youths aged between 13 and 19 living in the United Kingdom. Depressed mood was independently associated with both oppositionality and delinquency, but not with physical aggression. Dependent negative life events were strongly implicated in the association between delinquency and depressed mood, whereas depressogenic attributional style was implicated in the associations of both oppositionality and delinquency with depressed mood. Oppositionality remained a significant predictor of depressed mood after accounting for attributional style and life events whereas delinquency did not. The pattern of associations was largely similar in boys and girls. We discuss these results in terms of developmental models of the links between antisocial behavior and depressed mood.     

Reading problems and depressed mood

Although reading difficulties show well-established overlaps with disruptive behavior disorders in childhood, much less is known about reading-disabled children's vulnerability to emotional difficulties. Using longitudinal data from 6 assessments of boys in the Pittsburgh Youth Study, we found robust links between severe, persistent reading problems and increased risk for depressed mood in a community sample of boys aged 7 and 10 years at initial assessment, though not in those who had already entered their teens. These associations could not be accounted for in terms of selected family risks or comorbid disruptive behaviors; instead, the pattern of the findings pointed to the existence of more direct causal processes whereby reading problems influence younger boys' risk of depressed mood.     

Genetic and environmental influences on the relationships between family connectedness, school connectedness, and adolescent depressed mood: sex differences.

This study investigated (a) genetic and environmental contributions to the relationship between family and school environment and depressed mood and (b) potential sex differences in genetic and environmental contributions to both variation in and covariation between family connectedness, school connectedness, and adolescent depressed mood. Data are from 2,302 adolescent sibling pairs (mean age = 16 years) who were part of the National Longitudinal Study of Adolescent Health. Although genetic factors appeared to be important overall, model-fitting analyses revealed that the best-fitting model was a model that allowed for different parameters for male and female adolescents. Genetic contributions to variation in all 3 variables were greater among female adolescents than male adolescents, especially for depressed mood. Genetic factors also contributed to the correlations between family and school environment and adolescent depressed mood, although, again, these factors were stronger for female than for male adolescents.     

A suicidal adolescent's sleeping beauty syndrome: cessation orientations toward dying, sleep, and drugs

In a study of hospitalized suicidal youth, the account of a sixteen-year-old girl, diagnosed as schizophrenic, is analyzed to gain insight into a family's role in the suicidal career of an adolescent preoccupied with death and dying, sleep, and drugs; the interplay of her construction of reality with her risk-taking, self-injurious way of life; and her perceived problems of living and need for help. Her cessation orientations revealed a kind of Sleeping Beauty syndrome with fantasies on sleep, drugs, and death, including a death of the mind from overdosing. Such qualitative research on suicidal careers may increase our understanding of the at-risk adolescent population and assist in the development of a policy for identifying and meeting needs and following up on clues for prevention and early intervention.     

School Context and Genetic Influences on Aggression in Adolescence

Genetic and environmental contributions to variation in aggression were examined using adolescents' self-reports of aggressive behavior. The National Longitudinal Study of Adolescent Health provided a sample of 1,515 pairs of adolescents in five genetically informative groups (i.e., monozygotic twins, dizygotic twins, full siblings, half siblings, and unrelated siblings reared together). The analysis, a DeFries-Fulker regression within a hierarchical linear model, yielded findings on individual-level heritability (h2), shared environmental effects (c2), school-level effects, and school-level moderation of h2 and c2. The estimate of h2 for aggression in the full sample was .32, and c2 was .05. In the moderating effect, h2 increased and c2 decreased with greater school-level family warmth. Two effects on school means were found: Those schools with greater ethnic-racial heterogeneity had higher mean levels of aggression, and schools where students perceived greater family warmth had lower mean levels of aggression.     

Bobo clown aggression in childhood: Environment,not genes

We videotaped 216 twin children (average age: 7.6 years) hitting a 5-ft “Bobo clown”. Three behaviors in the Bobo clown situation showed adequate response characteristics, rater reliability, and test-retest reliability: number of hits, intensity of hits, and number of quadrants (into which the Bobo clown was hit). In terms of two “anchor” variables, height and weight, the twin correlations were representative of other studies in suggesting substantial hereditary influence. However, twin analyses of the three behavioral ratings during the Bobo clown session yielded no evidence of hereditary influence. Moreover, the results provided evidence of substantial environmental influence of the “between-family” variety. In other words, the family environment is the major source of individual differences for these measures.     

Traiter ses données proprement : vers un meilleur usage du data cleaning

Data cleaning has long been shown to be an essential step in data analysis but its application is not systematic and varies between researchers. The aim of the present article is to study the effect of the different elements of data cleaning and to give recommendations. The steps considered are normality, outliers and missing values. Firstly, we advise a close examination of the data and its normality with a view to transformation. Secondly, we look at outliers and their treatment (trimming and winsorizing). Lastly, we turn our attention to missing values and how to deal with them depending on their randomness. We also cover the importance of visualizing data before analysis. Finally, we illustrate the effect of these data cleaning practices on a real data set. We show that data cleaning can lead to a significant result becoming non-significant and therefore demonstrate the importance of these steps before starting data analysis.     

Skills training in the long-term management of stress and occupational burnout

The current managed healthcare environment stresses brief and effective short-term therapy. However, often this short-term treatment does not lead to long-term behavioral changes and clients return to therapy many times for help with the same dysfunctional behavioral patterns. The main problem with these traditional forms of treatment is the assumption that clients have the basic skills to change their ineffective behaviors. Yet, many people lack the basic skills to manage our highly stressful society, and may take years to master new behavioral management skills. Examining the relationship between stress and coping, this study explored both short-and long-term approaches to behavioral change relative to occupational burnout, and focused upon the teaching of skills to manage stress. Subjects who participated in a 6-week stressmanagement program reported only temporary decreases in burnout, while those subjects who received 1-hour coping “refresher” sessions at 5 months, 11 months, and 17 months showed consistent decreases in burnout throughout a 2 1/2 year period. These results suggest that psychologists can be much more effective behavioral change agents through long-term approaches that emphasize teaching new skills to manage chronic behavioral problems. Given the changes in the health insurance industry and the way therapeutic services are provided, the field may need to rethink approaches that are grounded in personality theory and abnormal psychology to approaches that emphasize principles of learning theory.
