New measure o f perceived motorcompetence for children ages 4 to 6 years

The purpose of this study was to develop and validate a test for the assessment of perceived motor competence in young children ages 4 to 6 years old. The structure of the Children's Perception of Motor Competence Scale was analyzed through exploratory and confirmatory factor analysis with 495 children between 4 and 6 years of age. A second-order model was selected and consisted of one scale of Perceived General Motor Competence and two subscales, Perceived Gross Motor Competence and Perceived Fine Motor Competence. The number of items was 22. This test showed acceptable internal reliability: global scale (alpha = .81), Perceived Gross Motor Competence (alpha = .80), and Perceived Fine Motor Competence (alpha = .65). Children manifested accuracy in the assessment of the competence. Perceived motor competence was related to actual motor competence as measured by the Movement ABC Test and by an observational scale used by Physical Education teachers. There were no sex differences. The Children's Perception of Motor Competence Scale could be considered an interesting assessment test for identifying current self-perceptions of motor competence in young children.     

Resistance to extinction of human evaluative conditioning using a between-subjects design

Two experiments were conducted to examine whether the resistance to extinction obtained in evaluative conditioning (EC) studies implies that EC is a qualitatively distinct form of classical conditioning (Baeyens, Eelen, & Crombez, 1995 a) or whether it is the result of an nonassociative artefact ( Field & Davey, 1997 , 1998 , 1999 ). Both experiments included between-subjects control groups in addition to standard within-subjects control conditions. In Experiment 1, only verbal ratings were measured in order to evaluate the effect of postacquisition CS-only exposures on EC whereas in Experiment 2, verbal ratings and postextinction priming effects were measured. The results showed that the EC effects are demonstrable in a between-subjects design and that the extinction procedure did not have any influence on the acquired evaluative value of CSs regardless of whether the verbal ratings or the priming effects were used as dependent variables. The present results provide evidence that EC is resistant to extinction and suggest an interpretation of EC as a qualitatively distinct form of associative learning.     

Risk Factors for Institutional Misconduct Among Incarcerated Women: An Examination of the Criterion-Related Validity of the Personality Assessment Inventory

This study tested the hypothesis that the Last-Weiss (Last &; Weiss, 1976) Rorschach Ego-Strength Scale would predict outcome among a representative sample of first-lifetime psychiatric admissions. One hundred seventeen patients were assessed with structured symptom, psychiatric history, and social data interviews at hospital admission, and 2-year follow-up. Outcome measures included a multidimensional variable involving rehospitalization time, social and work functioning, and recent symptom level and symptom measures. Unexpectedly, the Last-Weiss Sum E variable correlated significantly with negative multidimensional outcome, a result that was strengthened when any possibly confounding effects of social class, IQ, and number of Rorschach responses were partialled out. It was found that Sum E's predictive value for poorer outcome was due to the space response (S +) component of the ego-strength variable. Possible explanations of the findings and implications for the previously validated Klopfer's Rorschach Prognostic Rating Scale are discussed.

Factor structure and correlates of the dissociative experiences scale in a large offender sample

The authors examined the psychometric properties, factor structure, and construct validity of the Dissociative Experiences Scale (DES) in a large offender sample (N = 1,515). Although the DES is widely used with community and clinical samples, minimal work has examined offender samples. Participants were administered self-report and interview measures, and a subsample was followed longitudinally to determine criminal and violent recidivism. The DES exhibited good psychometric properties, but an identified three-factor structure was of questionable replicability. Moreover, the DES factors displayed no evidence of differential correlates. DES total scores were correlated with trauma-related variables even after controlling for negative affectivity. Total scores were related to measures of antisocial behavior and aggression but did not predict recidivism. These findings support the reliability and construct validity of the DES in offenders but raise questions regarding the clinical utility of the DES factor scores above and beyond that of the total score.     

The sequential analysis of transgressors' accounts of breaking environmental laws

Three-hundred and twenty written accounts of environmental transgressors were assessed by sequential analysis to reveal their argument streams. The accounts were obtained from the written statements that transgressors are allowed to give during the Spanish administrative process and which were included in files handled by four environmental law enforcement agencies. These agencies are distributed across national, regional, island and municipality jurisdictions. The setting for the study is a highly protected environment in which environmental laws have high salience. Results reveal that transgressors use simple argument streams, consistently more defensive than conciliatory, and questioning the perceived legitimacy of environmental law. It was seen also that the empirical functioning of the explanations related to pursuing emotional/prosocial objectives differs from what was expected from the traditional conceptual definition. Results are discussed in terms of how the assessment of the internal dynamic of the accounts would provide valuable information on transgressors' reasoning in relation to environmental laws.     

Improving attention behaviour in primary and secondary school children with a Computer Assisted Instruction procedure

Attention disorders are one of the major sources of poor school performance. This research project was designed to examine whether a Computer Assisted Instruction (CAI) approach would be successful in achieving higher rates of attention. In order to increase attention behaviour during school time, psychologically‐designed software was developed. The software, called “How to improve your mental skills,” consists of three games based on multimedia perception tasks. First, 155 elementary school children with an average age of 12.4 years, from Cadiz (Spain) School District, were evaluated with two attention tests, the Perception Differences Test (PDT), and the subtest Spatial of Primary Mental Aptitude (S‐PMA). Students were divided and balanced into one experimental and two control groups, according to their scores on the PDT. Then, 10 training sessions, of 25 minutes each, with the software “How to improve your mental skills”, were administered to the experimental group. Children from control group 1 played with a well‐known computer game during the same period of time, whereas children from control group 2 remained in the classroom with nonspecific training. Finally, after the experimental sessions, all the children were re‐evaluated with standard attention tests. Analyses of data included: (1) pre‐ and post‐training comparison of the experimental group scores on the PDT; (2) comparison of the experimental and control group 1 and 2 scores on the PDT and S‐PMA tests after training; and (3) gender and grade interference effects on attention behaviour. Results suggest that children from the experimental group significantly improved their attention behaviour as assessed by the PDT and S‐PMA tests after 10 training sessions with the specific computer software. No gender and grade interference effects on attention behaviour were found. Les désordres d'attention sont une des sources majeures de pauvre performance scolaire. Ce projet de recherche fut conçu pour examiner comment une approche d'enseignement assisté par ordinateur peut être efficace pour obtenir de plus hauts niveaux d'attention. Afin d'augmenter le comportement d'attention en classe, un programme informatique intitulé «Comment améliorer vos habiletés mentales» fut développé. Ce programme, basé sur la psychologie de la peception, consiste en trois jeux multimédias interactifs. L'étude s'est déroulée en trois phases. Premièrement, 155 enfants de L'école primaire, âgés en moyenne de 12,4 ans et issus du district scolaire de Cadiz, en Espagne, furent évalués à partir de deux tests d'attention: le Perception Differences Test (PDT) et le sous‐test Spatial of Primary Mental Aptitude (S‐PMA). Les élèves furent divisés en trois groupes, un groupe expérimental et deux groupes contrôle, en fonction de leur score au PDT. En deuxième lieu, le groupe expérimental fut soumis à 10 sessions d'entraînement, chacune d'une durée de 25 minutes, lors desquelles le programme informatique « Comment améliorer vos habiletés mentales » fut administré. Les enfants du premier groupe contrôle ont joué avec un autre programme informatique bien connu durant ces mêmes sessions, tandis que les enfants du second groupe contrôle demeuraient en classe sans recevoir d'entraînement particulier. En troisième lieu, tous les enfants furent réévalués à L'aide de tests d'attention standardisés. Trois séries d'analyses furent menées. La première visait à comparer les scores obtenus au PDT, au pré‐test et au post‐test, pour le groupe expérimental. La seconde consistait à comparer les scores obtenus au PDT et au S‐PMA, au post‐test, par les trois groupes. La troisième série d'analyses visait à examiner les effets du genre et du niveau de scolarité sur le comportement d'attention. Les résultats suggèrent que les enfants du groupe expérimental ont significativement amélioré leur comportement d'attention suite aux sessions d'entraînement avec le programme informatique. De plus, aucune interférence du genre et du niveau de scolarité ne fut observée. Los déficits de atención son una de las causas más frecuentes de fracaso escolar. La presente investigación se diseñó para someter a prueba si la Enseñanza Asistida por Ordenador (CAI) puede ser un procedimiento eficaz para conseguir mayores niveles de atención. Con el fin de conseguir una mejora de la atención en la escuela, se ha desarrollado un programa informático fundamentado en la psicología de la percepción que consiste en tres juegos interactivos multimedia. El estudio se realizó en tres fases. Primero, se evaluó a 155 niños de edad escolar del distrito de Cádiz (España) con dos pruebas estandarizadas de atención, Perception Differences Test (PDT), y sub‐test Spatial of Primary Mental Aptitude (S‐PMA). Tras ello, se formó un grupo experimental al que se realizaron 10 sesiones de entrenamiento de 25 minutos de duración cada una con el programa “Cómo mejorar tus habilidades mentales.” Otro grupo de alumnos a los que se les denominó control‐1 permanecieron jugando con un conocido juego informático durante el mismo período de tiempo. Los niños del grupo control‐2 permanecieron en sus clases sin un entrenamiento específico. Tras las sesiones experimentales, se evaluó de nuevo a todos los niños con las pruebas estandarizadas de atención. Primero, se comparó las calificaciones del grupo experimental en la PDT antes del entrenamiento y después del entrenamiento; segundo, se comparó las calificaciones del grupo experimental y de los grupos control 1 y 2 en las pruebas PDT y S‐PMA después del entrenamiento; y tercero, se analizó los efectos de interferencia del grado escolar y el género. Los resultados indican que los participantes del grupo experimental mejoraron su conducta atencional tras las sesiones de entrenamiento con el programa informático. No se encontraron efectos de interferencia del grado escolar o del género sobre la conducta de atención.     

Processing two tasks with varying task order: central stage duration influences central processing order

In a recent study, Sigman and Dehaene (2006, PLoS Biology, 4, 1227–1238) reported that perceptual processing duration influences processing order of two tasks in the psychological refractory period paradigm (PRP). The present study examines whether the duration of central processes also influences processing order. For this purpose, we employed letter tasks with different central processing durations and varied task order in the PRP. In one part of the experiment, a tone discrimination task was combined with a similar time-consuming letter discrimination task. In the other part, the tone task was combined with a more time-consuming letter task, which required a mental rotation of the letter thereby prolonging central processing. If the duration of central processes influences processing order, participants should perform the tone task first more often when it is presented with the more time-consuming mental rotation task, than when it is presented with the similar time-consuming letter task. The results clearly confirm this prediction and thus show that not only perceptual processing duration but also central processing duration affects processing order in a dual-task situation. We suggest that the reported effect mirrors a tendency of participants to minimize total reaction time to both tasks by reducing slack time.
