Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The purpose is to clarify the question of content strategy in police interviews of children. All 87 police interrogations with children from 30 disputable child sexual abuse cases with 41 children in Swedish courts have been examined concerning content strategies. Nearly all of these interviews can be described as extremely biased in their narrow selection of content around only one hypothesis. Six cases are briefly described and discussed to clarify the question of content strategy.

- Background. The study aimed to investigate patient and spouse perception of cognitive functioning 1 to 2 years after coronary artery bypass grafting.Methods. Seventy-six married patients who had undergone coronary artery bypass grafting were selected and sex- and age-matched with 75 concurrent married patients who had undergone percutaneous transluminal coronary angioplasty. Couples received a letter of explanation and then completed telephone interviews. Forty-seven questions assessed memory, concentration, general health, social functioning, and emotional state. Response choices were: improved, unchanged, or deteriorated function after coronary artery bypass grafting/percutaneous transluminal coronary angioplasty.Results. Patients who had undergone coronary artery bypass grafting did not differ in subjective ratings on any measure from patients who had undergone percutaneous transluminal coronary angioplasty. There were no differences between spouses in the respective groups; spouse ratings also did not differ from patient ratings. Only in memory function did patients and spouses report a postprocedural decline.Conclusions. No subjective differences were found in patients who had undergone either coronary artery bypass grafting or percutaneous transluminal coronary angioplasty. Spouse ratings agreed with each other and with patient ratings. Positive correlations were found between the questionnaire factors, suggesting that perceived health and well-being are associated with subjective cognition.

Personality traits and psychopathy (PCL-R) in male juvenile delinquents
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Abstract State-administered correctional institutions in Sweden take care of approximately 600 juvenile delinquents every year. The treatment for these institutionalized young people is based mainly on environmental programs and milieu therapy.Fifty-six conduct-disordered juvenile delinquents (mean age 17 years) from four institutions were studied with respect to their personality traits, and the prevalence of psychopathy (measured by the Hare Psychopathy Checklist – Revised, PCL-R). One objective was to study the reliability and validity of commonly used personality inventories. In particular, the validity of psychopathy-related personality traits, included in Schalling’s psychopathy model (1978), was examined by studying the relationships between personality traits and psychopathy (PCL-R), the occurrence of previous treatment occasions, and relapse into crime. Four groups, the delinquent participants, a group of high sensation-seekers (air force pilot recruits), normal male adolescent participants, and another group of normal young males, completed a number of personality inventories, which enabled us to obtain measures of personality traits. The personality inventories used were the Karolinska Scales of Personality (KSP), the Eysenck Personality Questionnaire, and the Zuckerman Sensation-Seeking Scales. In addition, the delinquent participants were rated on psychopathy according to the modified version of the PCL-R, designed to be used with young people (Fort, Hart, & Hare, 1990). Both variable-oriented (factor analysis, MANOVA) and person-oriented statistical methods (cluster analysis) were applied.As expected, most personality traits in the delinquent participants deviated from published norms and from our control groups. The delinquent participants showed a high level of pathology or vulnerability for developing mental disorders (such as substance abuse). About 60% of the delinquent participants had scores above 30 on the PCL-R, and were thus classified as psychopaths according to the manual. Further, 73% had scores between 27 and 40, indicating a high level of psychopathy. Delinquent participants showed a different pattern of sensation-seeking behavior than air force pilot recruits and normal adolescent participants, and differed also in other personality traits. They had a low level of socialization, indicating a lack of ability to take the role of the generalized other, and a tendency to impulsiveness, somatic anxiety and extraversion-sociability. The construct validity (convergent and divergent) of the KSP scales was found to be adequate. Some of the personality traits in delinquent participants, however, showed a different correlation pattern than that found in noncriminal people. Some of the basic scales from the KSP had high reliability, but many were not reliable when used on delinquent participants. Four factors were extracted using the maximum likelihood method. No significant correlations were found between the personality scale scores and the PCL-R scores. Finally, cluster analysis of the reliable and valid psychopathy-related personality scales from the KSP (Impulsiveness, Monotony avoidance, Socialization, Verbal aggression, and Somatic anxiety) identified seven different clusters of delinquent participants.The uncertain validity of some personality traits (e.g., psychoticism or detachment), the poor reliability of many of the KSP scales (e.g., Guilt, Suspicion, and Inhibition of aggression) when used on this population, together with some minor limitations of the studies (e.g., sample size) are discussed.In conclusion, the high prevalence of psychopathy in the present sample of male delinquent participants may have important clinical treatment implications, particularly since some researchers have suggested that milieu therapy increases relapse rates into crime in adult psychopaths. Hopefully, appropriate assessment of personality traits and psychopathy (in addition to obvious routine assessments of mental disorders, such as substance abuse or disabilities such as dyslexia), supervision, and the implementation of effective correctional programs, may prevent young people with deviant personalities from aggravating their deviant style of living. Key words: Personality traits, psychopathy (PCL-R), juvenile delinquents, reliability, validity, assessment.

- This study examined laypeople's understanding of a simple dynamic system, expressed in reasoning and strategies used by the subjects, and how it affected performance. Participants were 15 undergraduate psychology students, 4 male and 11 female; median age was 24 years, ranging from 21 to 31 years. The subjects' task was to establish equilibrium in a simple predator-and-prey system. A task analysis was performed to identify the problem structure, the vital aspects of the task, and the ideal strategies to perform the task. The subjects' actual performance was compared to these strategies. The results revealed that, even though the task was structurally simple, it was still difficult. Much of these difficulties seemed to stem from a low ability to apply indirect reasoning and thinking in terms of discrete time steps instead of in terms of continuous time.

Actor-Observer differences in realism in confidence and frequency judgments

Tidskriftsartikel (refereegranskat)abstract
- Taking a social psychological approach to metacognitive judgments, this study analyzed the difference in realism (validity) in confidence and frequency judgments (i.e., estimates of overall accuracy) between one’s own and another person’s answers to general knowledge questions. Experiment 1 showed that when judging their own answers, compared with another’s answers, the participants exhibited higher overconfidence, better ability to discriminate correct from incorrect answers, lower accuracy, and lower confidence. However, the overconfidence effect could be attributable to the lowest level of confidence. Furthermore, when heeding additional information about another’s answers the participants showed higher confidence and better discrimination ability. The overconfidence effect of Experiment 1 was not found in Experiment 2. However, the results of Experiment 2 were consistent with Experiment 1 in terms of discrimination ability, confidence, and accuracy. Finally, in both experiments the participants gave lower frequency judgments of their own overall accuracy compared with their frequency judgments of another person’s overall accuracy.
