Intelligence and the Frontal Lobe: The Organization of Goal-Directed Behavior

Basic to the study of individual differences is the concept of “general intelligence” or Spearman'sg.In this article we suggest thatgis largely a reflection of the control functions of the frontal lobe. A series of experiments investigates a phenomenon we callgoal neglect:disregard of a task requirement even though it has been understood and remembered. Subjectively it is as though the neglected requirement “slips the subject's mind.” Previously described in frontal patients, we show that goal neglect can also be seen in some members of the normal population. In line with conventional distinctions between controlled and automatic processing, eliciting conditions for goal neglect include novelty, weak error feedback, and multiple concurrent task requirements. Under these conditions neglect is linked closely togand extremely common after frontal lesions. Following many other models, we suggest that behavior in any task is structured by a set of action constraints or requirements, derived in part from verbal instructions and specified at multiple levels of abstraction. A frontal process of constraint or requirement activation is fundamental to Spearman'sg.     

The Feasibility,Appropriateness, Meaningfulness,and Effectiveness of Parenting and Family Support Programs Delivered in the Criminal Justice System: A Systematic Review

Children whose parents are involved in the criminal justice system (CJS) are at increased risk of developing social, emotional, and behavioural difficulties and are more likely than their peers to become involved in the CJS themselves. Parenting behaviour and parent-child relationships have the potential to affect children’s outcomes with positive parenting practices having the potential to moderate some of the negative outcomes associated with parental involvement in the CJS. However, many parents in the CJS may lack appropriate role models to support the development of positive parenting beliefs and practices. Parenting programs offer an opportunity for parents to enhance their parenting knowledge and behaviours and improve relationships with children. Quantitative and qualitative evidence pertaining to the implementation and effectiveness of parenting programs delivered in the CJS was included. Five databases were searched and a total of 1145 articles were identified of which 29 met the review inclusion criteria. Overall, programs were found to significantly improve parenting attitudes; however, evidence of wider effects is limited. Additionally, the findings indicate that parenting programs can be meaningful for parents. Despite this, a number of challenges for implementation were found including the transient nature of the prison population and a lack of parent-child contact. Based on these findings, recommendations for the future development and delivery of programs are discussed.     

Just how Emotionally Intelligent are Religious Leaders in Britain? A Study among Anglican Clergy in Wales

This study explores the profile of 364 Anglican clergy serving in the Church in Wales (264 clergymen, 93 clergywomen, and 7 who did not disclose their sex) on the Schutte Emotional Intelligence Scale. The data confirm the finding from three earlier studies of church leaders in Britain that both male and female clergy in Britain record significantly lower levels of emotional intelligence in comparison with the standardization data published for this scale. Closer investigation of the scale items, however, questions whether this instrument may offer a fair assessment of the kind of emotional intelligence best suited for pastoral ministry.

     

A cross-cultural investigation of cognitions and depressive symptoms in adolescents

Adolescents (N=2,272) from Hong Kong and the United States provided information regarding their depressive symptoms, cognitions (self-efficacy, negative cognitive errors, and hopelessness), and stressful events between 2 surveys 6 months apart. Depressive symptoms and hopelessness were higher, and self-efficacy and negative cognitive errors were lower in Hong Kong than in the United States. Cognitions were associated with concurrent depressive symptoms and predicted depressive symptoms 6 months later in both cultures. The "reverse" model was also supported with more variance predicted by depressive symptoms to later cognitions than from cognitions to depressive symptoms. There was some support for the hypothesis that self-efficacy is less salient in collective compared with individualistic cultures. These findings extend cognitive theories of depression to a non-Western culture.     

Executive Functioning in Children and Adolescents with Major Depressive Disorder

The present investigation examined neurocognitive functioning, focusing on executive functioning (EF), in 39 children and adolescents with Major Depressive Disorder (MDD) and 24 healthy control subjects all ages 8 to 17 years. The Wechsler Intelligence Scale for Children-Third Edition along with several measures of executive functioning including the Wisconsin Card Sorting Task, Trail Making Test, Controlled Oral Word Association Test, and the Stroop Color Word Test were administered. The neurocognitive profiles for the group of depressed children and adolescents were grossly intact as most scores on intellectual and EF measures fell within the average range and did not differ from the comparison group. Mental processing speed was decreased in the MDD versus normal control group and 27% of the depressed group performed below average on the Trail Making Test. This investigation provided a good base from which to compare future literature on EF in outpatients with early-onset MDD.     

Personal versus interpersonal contributions to depressive symptoms among Hong Kong adolescents

Cross‐cultural theory proposes that an essential distinction between cultures lies in the extent to which individual members see themselves as either independent agents preferentially valuing agency and efficacy, or as embedded within a social context preferentially valuing interpersonal relationships. A nonreferred sample of 605 boys and 503 girls from Hong Kong provided information regarding: (1) perceptions of their personal self‐efficacy or beliefs regarding their own ability to master challenges they face; (2) the degree of harmony in their interpersonal (peer and family) relationships; and (3) depressive symptoms as an assessment of their mood. Cognitive theories of emotions propose that both the individual's assessment of his/her self‐efficacy and of his/her relationships influence mood. Hypotheses, based on cross‐cultural theory, were that in this collective culture, interpersonal evaluations would predict more of the variance in mood than would personal self‐efficacy. Contrary to Western sex‐differences literature, it was predicted that the effect of interpersonal harmony on mood would be equally pronounced for girls and for boys. Structural equation modelling was used to test causal models. Consistent with findings from the West, evaluations of personal self‐efficacy as well as interpersonal relationship harmony were significantly associated with depressed mood. Consistent with cultural theory, interpersonal relationship harmony was more strongly associated with mood than was personal self‐efficacy for the entire sample of adolescents. In contrast to findings of sex differences in the salience of relationships in the West, the prediction of interpersonal relationships to mood was equal for boys and girls in Hong Kong. This preliminary study extends models of cognitive concomitants of mood disruption to a non‐Western culture, and provides a framework to understand relative contnbutors to mood in adolescence. The findings tentatively suggest that treatment for depressive mood in Chinese populations should prioritize enhancement of the perceived quality of interpersonal relationships over increasing a sense of mastery.     

Developing Cognitive Behavioral Therapy to Prevent Depressive Relapse in Youth

Relapse rates for children and adolescents with major depressive disorder (MDD) range from 30% to 40% within 1 to 2 years after acute treatment. Although relapse rates are high, there have been relatively few studies on the prevention of relapse in youth. While acute phase pharmacotherapy has been shown to reduce symptoms rapidly in depressed youth, children and adolescents frequently report ongoing residual symptoms and often relapse following acute treatment. Recent adult trials have begun examining augmentation with psychosocial treatment after successful medication treatment to enhance medication response and prevent future relapse. This strategy has not yet been examined in youth with depression. Here we present initial efforts to develop a sequential, combination treatment strategy to promote rapid remission and to prevent relapse in depressed youth. We describe efforts to adapt CBT to prevent relapse (RP-CBT) in youth who respond to pharmacotherapy. The goals of RP-CBT include: preventing relapse, increasing wellness, and developing skills to promote and sustain well-being. We describe the rationale for, components of, and methods used to develop RP-CBT. The results from a small open series sample demonstrate feasibility and indicate that youth appear to tolerate RP-CBT well. A future test of the treatment in a randomized controlled trial is described.     

Changes in Behaviour and Body Weight Following a Single or Double Social Defeat in Rats

In a series of experiments, the consequences of a single and double social conflict on various behaviours and body weight in rats were studied. Animals were subjected to social defeat by placing them into the territory of an aggressive male conspecific for one hour, either once, or twice at the same time on two consecutive days. To assess the consequences of social defeat, three experiments were performed with independent groups of rats. In the first experiment, an open field test was performed two days after the last conflict. Locomotor activity was strongly reduced after social defeat. There were no differences between the single and double defeat group. To assess the effects of social defeat on subsequent social behaviour, a second experiment was performed in which experimental animals were confronted with an unfamiliar non-aggressive rat two days after a single or double conflict. Social defeat resulted in a reduction of social contact with the unfamiliar conspecific. There was no difference between the single and double conflict group. In the third experiment, the effects of social conflict on food intake, body weight and saccharine preference were measured. Food intake was not affected after a single conflict, but in the double conflict group food intake was decreased for several days. Body weight gain was decreased after both single and double social defeat. The decrease was stronger in the double conflict group. Water intake and saccharine preference were not significantly affected. This study revealed that social defeat in rats causes pronounced changes in various behaviours and body weight. Different aspects of behaviour are differentially affected by defeat with respect to the magnitude and time course of the changes induced. Moreover, different behavioural parameters are differentially sensitive to repetition of the stressor.
