Opposing determinants of compliance and interrogative suggestibility

The Gudjonsson Suggestibility Scales (GSS 1 & 2) can illuminate social and cognitive factors which affect forensic interviewees’ vulnerability to pressure from interrogators. Variations of the GSS procedure can highlight detail in the dynamics of interrogative suggestibility (IS). Induced malingering is one such variation. The present study used this method in an attempt to reconcile conflicting findings of two previous malingering studies. An innovation was to pre-test participants on the standard GSS 2 to identify them as showing Low, Medium, or High IS. These groups then undertook the parallel GSS 1 but with the instruction to role-play a suspect who is attempting to appear abnormally suggestible. Results showed marked differences in the direction in which faking scores changed, from those at pre-testing, between the Low and the High groups, with the High group showing a decrease in GSS scores and the Low group an increase: the Medium group scores followed the trend of the Low group scores. It is suggested that these results explain why previous results using induced malingering have been inconsistent. The results are also discussed in terms of how differing expectancies and levels of interpersonal trust may affect interviewees.     

Assessing Effort During Neuropsychological Evaluation with the TOMM in Children and Adolescents with Epilepsy

Effort assessment is of particular importance in pediatric epilepsy where neuropsychological findings may influence treatment decisions, especially if surgical interventions are being considered. The present investigation examines the Test of Memory Malingering (TOMM) in 60 children and adolescents with epilepsy. The overall pass rate for the sample was 90%. TOMM scores were unrelated to age, though there was a significant correlation between TOMM Trial 2 scores and intelligence estimates. Overall, the TOMM appears to be a valid measure of effort in young epilepsy patients, though caution should be used when interpreting scores for those with very low IQ, especially if behavioral problems are also evident. Caution should also be exercised in interpreting scores in children with ongoing interictal epileptiform activity that may disrupt attention.

Comorbidity of DSM-IV Personality Disorders in unipolar and bipolar affective disorders: a comparative study

The aim of this study was to compare the prevalence of Personality Disorders assessed by Structured Clinical Interview for Axis-II in 155 inpatients diagnosed with Unipolar Disorder vs inpatients with Bipolar Disorder (39). The most frequent Axis II diagnoses among Unipolar inpatients were Borderline (31.6%), Dependent (25.2%), and Obsessive-Compulsive (14.2%) Personality Disorders. Among Bipolar inpatients, the most prevalent personality disorders were Borderline (41%), Narcissistic (20.5%), Dependent (12.8%), and Histrionic disorders (10.3%). Using chi squared analysis, few differences in distribution emerged between the two groups: Unipolar patients had more recurrent Obsessive-Compulsive Personality Disorder than Bipolar patients (chi(1)2=6.24, p<.005). Comorbid Narcissistic Personality Disorder was significantly more frequent in the Bipolar than in the Unipolar group (chi(1)2=6.34, P<.01). Considering the three clusters (DSM-IV classification), there was a significant difference between the groups, Cluster C (fearful, avoidant) diagnoses being more frequent in the Unipolar than in the Bipolar group (48.4% vs 20.5%, respectively). Cluster B (dramatic, emotionally erratic) diagnoses were found more frequently in patients with Bipolar Disorders (71.8% vs 45.2% in Unipolar patients, chi(2)2=10.1, p<.006). The differences in the distribution and prevalence of Personality Disorders between the two patient groups are discussed.     

Future time perspective and motivational categories in Argentinean adolescents

This study is based on a sample of 332 Argentinean teenagers in their last year of secondary school. In the context of the relational theory of motivation, an attempt is made to determine the motivational categories best predicting Future Time Perspective (FTP) extension. The influence of the sex, locus of control, social class, and school ethos variables on FTP extension is also explored. A scale measuring locus of control and the Motivational Induction Method (MIM) have been employed to obtain the data. Through stepwise multiple regression, a predictive set is determined, made up of life-meaning values, self-fulfillment, academic achievement motivation, locus of control, sensual values, and social contact. Significant differences are found in FTP extension and locus of control in relation to school ethos. The Mann-Whitney and Kruskal-Wallis tests are used as statistical proof. A one-way ANOVA is run to examine the relationship between locus of control and school ethos levels. The possibility of a motivational profile common to Argentinean teenagers is considered and the pedagogical consequences of the findings are discussed.     

How do young children determine location? Evidence from disorientation tasks

Previous studies show that following disorientation children use the geometry of an enclosed space to locate an object hidden in one of the corners [e.g. (Hermer, L., & Spelke, E. (1996). Modularity and development: A case of spatial reorientation. Cognition, 61, 195-232)]. These studies have used a disorientation procedure that involves rotating the viewer (with eyes closed). Here, we examine 18- to 25-month-olds' spatial coding in two disorientation tasks--involving either viewer or space rotation. Importantly, the rotational movements in both tasks could not be visually tracked. Children were tested in either task (viewer- or space-movement) from either inside or outside a triangular (isosceles) space (with one unique and two equivalent corners). In the viewer-movement task, performance was above chance, regardless of which corner contained the object. In the space-movement task, performance was above chance at only the unique corner. On both tasks, performance was better from inside the space than from outside. The implications for how children determine location are discussed.     

Influence of word class proportion on cerebral asymmetries for high- and low-imagery words

It has been claimed that the typical RVF/LH advantage for word recognition is reduced or eliminated for imageable, as compared to nonimageable, nouns. To determine whether such word-class effects vary depending on the stimulus list context in which the words are presented, we varied the proportion of high- and low-image words presented in a lateralized lexical decision task (0, 25, 50, 75, or 100% high image). Although the RVF/LH advantage for high-image words was unaltered by word-class proportion, a significant linear trend was obtained for the low-image words such that the RVF/LH advantage increased as the proportion of low-image words increased. We discuss the implications of these findings for models of how lexical processing is distributed across hemispheres.     

The moderating role of early traumatic experiences on the association of schizotypal traits with visual perception

The findings on the association of schizotypal traits with the perception of visual illusions are scarce and inconsistent and have not taken into consideration potential effects of childhood traumatic experiences, a risk factor for schizophrenia-spectrum conditions. Thus, the present study addressed the question of potential moderating effects of early traumatic experiences on the association between different aspects of schizotypal traits with the perception of the Müller-Lyer and Navon's Hierarchical Letters (NHL) illusions. The study revealed that (a) increased suspiciousness was associated with increased liability to the Müller-Lyer illusion, when the exposure to traumatic events was high, whereas the opposite pattern was true when the exposure to traumatic events was low; (b) negative schizotypy was associated with more accurate global perception, and high disorganized schizotypy was associated with superior accuracy when target letters were present during the NHL illusion, when early traumatic experiences were at lower levels; and (c) high negative, disorganized, and total schizotypy were associated with lower accuracy when target letters were present in the NHL paradigm, when early traumatic experiences were at higher levels. The findings of the study suggest that early traumatic events differentially moderate the relationship between various aspects of schizotypal traits and visual perceptual processing.     

Experimental manipulations of responsibility: An analogue test for models of Obsessive-Compulsive Disorder

Several authors attribute excessive responsibility a predominant role in Obsessive-Compulsive Disorder (OCD) [Salkovskis, P. M. (1985) Behaviour Research and Therapy, 23, 571–583; Rachman, S. (1993) Behaviour Research and Therapy, 31, 149–154; van Oppen, P. & Arntz, A. (1994) Behaviour Research and Therapy, 32, 79–87]. The present studies aimed at demonstrating the link between different levels of perceived responsibility and checking behaviors by experimentally manipulating responsibility in non-clinical Ss. In the first study, a sound recognition task was used to compare checking behaviors in Ss with high (HR) and low (LR) perceived responsibility. Only one variable was significantly different, Ss from the HR group reporting more anxiety during the task than Ss from the LR group. Results did not support a link between responsibility and checking behavior. In a second study HR and LR Ss were compared on a manual classification task. Subjects from the HR group hesitated and checked more, and reported more preoccupation with errors and anxiety during the task than Ss from the LR group. Since perceived severity of the outcome was the most variable affected by the manipulation, the implications for current models of OCD are discussed and an alternative explanation is attempted. Finally, clinical implications are examined and suggestions are made for future directions of research.     

Self-derogating consequences of sex-based preferential selection: The moderating role of initial self-confidence

One hundred and twenty undergraduates (60 male and 60 female) served as leaders for a one-way communication task. They were selected for the leadership position on the basis of merit or preferential selection. Among those selected preferentially, one group was given no information, another group was given positive information, and a third group was given negative information about their task-related leadership ability. As expected, when selected preferentially and provided with no ability information, males did not differ in self-views but females were far more negative in self-views than those selected on the basis of merit. However, when provided with positive information about task-related ability women selected preferentially did not differ in self-view from those selected on the basis of merit, and when provided with negative information about task-related ability men selected preferentially did evidence more negative self-views then those selected on the basis of merit. Measures of self-view included evaluations of performance, perceptions of general leadership ability, and desire to persist in the leadership role. The findings lend support to the idea that confidence in task-related ability is an important determinant of reactions to preferential selection. Implications of these findings, both theoretical and practical, are discussed.
