The development of a systemic school-based intervention: Marte Meo and coordination meetings

Antisocial behavior is often persistent, and in addition to causing suffering to children and their families, it also poses considerable costs for society. Children who display externalizing behavior in their early years run a high risk of having severe problems later in life. There is a need for treatment methods that may be used in various settings because these children constitute a group that is hard to reach with conventional treatment methods. In addition, the dropout rate from ordinary treatment is often high. In the present study, a systemic school-based model for early detection and intervention among 4-12-year-old children who displayed externalizing behavior problems was developed and examined in a nonrandomized study in the county of Skaraborg in Sweden. The intervention was collaborative and included a combination of the Marte Meo model and coordination meetings based on systemic theory and practice. Treatment effects in the group who had received the intervention were compared with a group who had received treatment as usual in their ordinary school setting. Assessments were carried out before, and 2 years after, the intervention. For the intervention group (N = 33), there was a significant decrease in the children's reported symptoms in school and in the home. No decrease in externalizing behavior was found in the comparison group (N = 16). There were no dropouts in the intervention group after the intervention had begun. The results are promising; the study demonstrates that it is possible to work effectively with many children who display externalizing behavior problems in a nonclinical setting.     

Child witnesses' metamemory realism

This study investigated the degree of realism in the confidence judgments of 11 to 12-year-olds (41 girls and 40 boys) of their answers to questions relating to a short film clip showing a kidnapping event. Four different confidence scales were used: a numeric scale, a picture scale, a line scale and a written scale. The results demonstrated that the children showed a high level of overconfidence in their memories. However, no significant differences between the four confidence scales were found. Weak gender differences were found in that the girls were slightly, but significantly, better calibrated than the boys. In addition, although both boys and girls overestimated the total number of memory questions they had answered correctly, the boys gave higher estimates compared with the girls. In brief, the results indicate that, at least in the context investigated, 11-12 year-old children's confidence in and estimations of their own event memory show poor realism (overconfidence and overestimation). A comparison with previous research on adults indicates that 11 to 12-year-old children show noticeably poorer realism.     

Inferring causality assessments from predictive responses: cue interaction without cue competition

The authors criticize the use of participants' predictive responses during a learning phase as a measure of causal assessments. Simulations demonstrate that a general aim to minimize error as required in the prediction task will produce results in accordance with those observed, in particular apparent cue interaction effects. It is argued that measures estimated from prediction responses do not reflect causal ratings, but are side-effects of learning explained by adaptation in strategy to changes in presented cell frequencies. The results are reinterpreted to be in line with a causal model view, not requiring dual processes or cue competition of lower level associative processes.     

Eyewitness testimony: tracing the beliefs of Swedish legal professionals

This paper examines beliefs held by Swedish legal professionals about eyewitness testimony. In a survey including questions about 13 key issues of eyewitness testimony, three groups were investigated: police officers (n = 104), prosecutors (n = 158), and judges (n = 251). The response rate was 74%. Examples of findings are that the beliefs were in line with scientific findings concerning the weapon focus effect, but were not in line for simultaneous vs. sequential lineups. Between-group differences were found for seven items. Judges were much more sceptical than police officers about the reliability and completeness of children's testimonies. The groups seldom agreed about one answer alternative, and they reported not being up to date about scientific research on eyewitness testimony. The results suggest that some important research findings have reached those working on the field. However, they hold many wrongful beliefs about eyewitness testimony, beliefs that might compromise the accuracy of legal decisions.     

Exceptional memorizers: made,not born

In a recent study, Maguire and colleagues failed to find systematic differences in brain anatomy between world-class memory performers and matched control subjects. The world-class performers exhibited distinctive patterns of brain activation during memorization, but these patterns were directly attributable to the experts' unique encoding strategies and acquired memory skills. Discussed here are the implications for broad attainability of highly skilled memory performance in professional and everyday activities.     

A measure for the assessment of eating disorders: reliability and validity studies of the Rating of Anorexia and Bulimia interview - revised version (RAB-R)

The Rating of Anorexia and Bulimia interview (RAB) is a Swedish semi-structured interview for clinical and research purposes for a wide range of eating disorder symptoms and related psychopathology. The objectives were to evaluate the reliability and validity of a revised RAB version (RAB-R). The RAB-R was assessed in terms of internal consistency, inter-rater and test-retest reliability, and criterion and convergent validity. Samples included a clinical sample of eating disorder patients (n = 71) and a sample of randomly drawn female controls (n = 31). The RAB-R showed satisfactory internal consistency, inter-rater and test-retest reliability, correlated well with related measures, and discriminated between patients and normal controls. We conclude that the RAB-R is a promising interview instrument and continued evaluation should focus on comparing subgroups of eating disorder patients with other clinical groups.     

Unconditioned sexual incentive motivation in the male Norway rat (Rattus norvegicus)

Sexual incentive motivation was evaluated in a procedure consisting of a large open field where incentive animals were confined behind wire mesh openings. When sexually inexperienced male rats (Rattus norvegicus) were exposed to the receptive female-male incentives, they spent more time close to the female. If the incentives were receptive female-nonreceptive female, the receptive female was preferred. However, when the alternatives were nonreceptive female-male, no preference was obtained. Castration abolished preference for the receptive female, and treatment with testosterone propionate restored it. Estradiol plus oil is as efficient as estradiol plus progesterone for giving the ovariectomized female incentive properties. The living female can be replaced with female odor. Sexual experience did not have any long-term effects on the female's incentive value, but immediately preceding limited sexual activity enhanced it     

Cognitive processes operating in hindsight

The aim of this investigation was to study the cognitive processes involved in the "knew-it-all-along" effect, especially in regard to use of inferential processes. The results of three experiments showed that the magnitude of the phenomenon did not increase with more use of inferential processes. It is proposed that only under misleading circumstances do inferential processes associated with overconfidence increase the magnitude of the phenomenon. For a majority of the tasks introspectively classified as solved by pure guessing, the hindsight phenomenon entirely disappeared whereas "intuition" tasks lead to the strongest bias. The results are generally consistent with the accuracy-assessment model (A. Winman et al. , 1998).     

Discriminant validation of measures of organizations commitment,job involvement,and job satisfaction among Swedish army officers

The discriminant validity of measures of job involvement, job satisfaction and organizational commitment was tested with data from 467 army officers in Sweden. Confirmatory-factor analysis showed a close fit between the proposed three-factor model and the data. Further, six of eleven job and health correlates related differently to the three attitude vairables. The results indicate that job involvement, job satisfaction and organizational commitment represent three empirically distinct constructs. Implications for future research discussed.
