Aggressive adolescents in residential care: a selective review of treatment requirements and models

This article presents a selective inventory of treatment methods of aggressive behavior. Special attention is paid to types of intervention that, according to research, are frequently used in Dutch residential youth care. These methods are based on (1) principles of (cognitive) behavior management and control, (2) the social competence model, and (3) influencing the peer culture. Suggestions are made as to how the treatment of aggressive adolescents may be realized in residential settings. The article concludes that more attention should be paid to the involvement of parents and to the part played by the peer group in the treatment of aggressive behavior.     

Maintaining readiness for mental rotation interferes with perceptual processes in children but with response selection in adults

Previous work revealed that mental rotation is not purely inserted into a same-different discrimination task. Instead, response time (RT) is slowed to upright stimuli in blocks containing rotated stimuli compared to RT to the same upright stimuli in pure upright blocks. This interference effect is a result of maintaining readiness for mental rotation. In two experiments we investigated previous evidence that these costs depend upon distinct sub-processes for children and for adults. In Experiment 1, the maintaining costs turned out to be independent of the visual quality of the stimulus for adults but not so for children. Experiment 2 revealed that the maintaining costs were greatly reduced for adults when they performed mental rotation as a go-no-go task, but not so for children. Taken together, both experiments provide evidence that whereas perceptual processes seem to be important for school-age children to maintain readiness for mental rotation, response selection is relevant for adults.     

Cognitive-behavioral therapy versus temporal pulse amplitude biofeedback training for recurrent headache

Sixty-four headache sufferers were allocated randomly to cognitive-behavioral therapy (CBT), temporal pulse amplitude (TPA) biofeedback training, or waiting-list control. Fifty-one participants (14M/37F) completed the study, 30 with migraine and 21 with tension-type headache. Treatment consisted of 8, 1-hour sessions. CBT was highly effective, with an average reduction in headaches from pre- to posttreatment of 68%, compared with 56% for biofeedback, and 20% for the control condition. Headaches continued to decrease to 12 month follow-up for CBT. Improvement with CBT was associated with baseline coping skills, social support, and physiological measures at rest and in response to stress, particularly TPA. Changes on some of these measures were correlated with changes in headaches. No significant predictors of response to biofeedback emerged.     

Narcissistic mortification of ageing men

The development of a male gender identity involves the task of relinquishing the identification with the female primary object. If this separation is experienced as loss or expulsion, and responded to by the development and libidinous cathexis of phallic-narcissistic characteristics, a specifically male narcissistic vulnerability emerges, which can, particularly in ageing men, escalate to critical proportions. However, phallic-narcissistic crises in the ageing process also contain opportunities for development, provided the losses of age can be faced with mourning. The author sets out the statements on the subject of old age in the myth of Narcissus and makes use of the concepts of developmental psychology. He outlines clinical examples illustrating this problem. Finally, he brings to mind the narcissistic plight of the aged Oedipus.     

State IQ and suicide rates in the United States

Previous findings pertaining to the direction (positive or negative) of the ecological correlation between intelligence and suicide rates in the USA have been conflicting. Using novel state IQ estimates, derived from the Scholastic Assessment Test, the American College Test, these tests combined, or the National Assessment of Educational Progress state scores, these estimates were not consistently associated to state suicide rates. Whereas ACT-derived state IQ was significantly positively correlated with suicide rates, the correlation with composite ACT-SAT-derived state IQ was significantly negative and with both SAT-derived and NAEP-derived state IQ also negative but not significant. Validity checks pointed to possible methodological problems with the state IQ estimates. Currently available estimates of state IQ, therefore, seem not appropriate to resolve the question of the direction of the ecological correlation of intelligence and suicide mortality across the USA.     

Investigating a computerised test of the Stroop effect extended by inclusion of a third, more difficult task

A validation study of a computerised test recently developed involving the Stroop effect, extended here by inclusion of a third, more difficult test series, is presented. Three groups of men belonging to the Swedish armed forces and adjudged to differ in their qualifications (20, 32, and 19 men of levels 1, 2, and 3, respectively) and a fourth group of 18 men convicted of serious crimes of violence were given this test, termed the Stress Strategy Test. Discriminant analysis of the test's 12 variables (four for each of the three test series) yielded a discriminant power of 65% for the total group, highest for the level 1 group (80%) and for the nonmilitary group (72%), results substantially better than obtained for the original version of the test with use of similar subject groups.     

Locus of control, self-control, and family income as predictors of young children's mathematics and science scores

Locus of control, self-control, and family income were investigated as possible predictors of 138 young children's mathematics and science scores. The children, 60 boys and 78 girls, ranging from 4 to 8 years of age (M = 5.4, SD = 1.3) were administered the Stephens-Delys Reinforcement Contingency Interview Scale, the Self-control Rating Scale, the Comprehensive Mathematics Inventory, and a science test based on the work of D. K. Dickinson. Analysis showed mathematics scores were positively related to income, locus of control, and science scores. Mathematics and science scores were negatively related to lack of self-control. Also, science scores were positively related to locus of control. Multiple regression analysis with mathematics as the dependent variable indicated income had the greatest predictive value followed by self-control and locus of control. The multiple regression model of science was also significant, with locus of control having the greatest influence followed by self-control.     

Exploiting redundancy for flexible behavior: unsupervised learning in a modular sensorimotor control architecture

Autonomously developing organisms face several challenges when learning reaching movements. First, motor control is learned unsupervised or self-supervised. Second, knowledge of sensorimotor contingencies is acquired in contexts in which action consequences unfold in time. Third, motor redundancies must be resolved. To solve all 3 of these problems, the authors propose a sensorimotor, unsupervised, redundancy-resolving control architecture (SURE_REACH), based on the ideomotor principle. Given a 3-degrees-of-freedom arm in a 2-dimensional environment, SURE_REACH encodes 2 spatial arm representations with neural population codes: a hand end-point coordinate space and an angular arm posture space. A posture memory solves the inverse kinematics problem by associating hand end-point neurons with neurons in posture space. An inverse sensorimotor model associates posture neurons with each other action-dependently. Together, population encoding, redundant posture memory, and the inverse sensorimotor model enable SURE_REACH to learn and represent sensorimotor grounded distance measures and to use dynamic programming to reach goals efficiently. The architecture not only solves the redundancy problem but also increases goal reaching flexibility, accounting for additional task constraints or realizing obstacle avoidance. While the spatial population codes resemble neurophysiological structures, the simulations confirm the flexibility and plausibility of the model by mimicking previously published data in arm-reaching tasks.     

Cross-cultural comparison of motivation to learn in physical education: Japanese vs Swedish schoolchildren

The present study compared differences between Japanese and Swedish schoolchildren in learning motivation-related variables in physical education. The subjects were 1,562 Japanese fifth and sixth graders (776 boys and 786 girls) ranging in age from 10 to 12 years and 573 Swedish fifth graders (306 boys and 267 girls) from 10 to 13 years (M = 11.4, SD = 0.5). They completed three questionnaires to evaluate the children's learning motivation, factors supporting motivation to learn, and preferences of learning behavior. The questionnaires were taken from Nishida's Diagnosis of Learning Motivation in Physical Education Test, a multidimensional and comprehensive test that measures learning motivation. A 2 x 2 (country by sex) multivariate analysis of variance indicated both Swedish boys and girls scored significantly higher than the Japanese children on most subscales. Results were discussed in relation to differences in the sports environment and culture of the two countries.     

Psychometric properties and correlates of the Lester-Bean Attribution of Causes to Suicide Scale (German form)

Psychometric properties and correlates of the German form of Lester and Bean's 1992 Attribution of Causes to Suicide Scale, of 18 items tapping into lay theories of suicide (intrapsychic problems, interpersonal conflicts, and societal forces as causes), were investigated in a sample of the general population in Austria (n=156). The three attributional dimensions presented moderate internal consistencies and the 18 items appeared to be factorially orderly, as indicated by exploratory factor analysis. Previous results were replicated, with positive interrelations among all three dimensions, but these were largely confined to men. Societal causes of suicide were significantly less frequently endorsed than intrapsychic or interpersonal causes. Respondents' sex, intelligence, and knowledge about suicide were unrelated, and scores on the Big Five personality factors and social desirability were largely unrelated to the three dimensions. Endorsing intrapsychic causes to suicide was correlated with advanced age, religiosity, and conservative political orientation, and the three dimensions entertained meaningful associations with locus of control (internality, social externality, and fatalistic externality). All observed demographic and attitudinal correlates were, however, of modest magnitude. Implications of the findings and directions for further inquiry are discussed.
