Goal orientation and ability: interactive effects on self-efficacy,performance, and knowledge

This study examined the direct relationship of goal orientation--and the interaction of goal orientation and cognitive ability--with self-efficacy, performance, and knowledge in a learning context. The authors argue that whether a particular type of goal orientation is adaptive or not adaptive depends on individuals' cognitive ability. Consistent with previous research, learning orientation was positively related to self-efficacy, performance, and knowledge, whereas performance orientation was negatively related to performance only. The interactions between goal orientation and ability also supported several hypotheses. As expected, learning orientation was generally adaptive for high-ability individuals but had no effect for low-ability individuals. In contrast, the effects of performance orientation were contingent on both individuals' level of cognitive ability and the outcome examined.     

Reliability and construct validity for scale of rejection of Christianity

A sample of 16 male and 30 female undergraduates completed the Greer and Francis Scale of Rejection of Christianity. The data support the internal consistency reliability and construct validity of the scale for this sample.     

Reframing DSM-IV: Positive Strategies From Developmental Counseling and Therapy

Professional counselors in educational and mental health settings all must deal with so-called psychopathology. At issue is how can they work with “disorder” from a positive, developmental perspective? Developmental counseling and therapy (DCT) offers an approach to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (American Psychiatric Association, 1994) classification systems that enables the reframing of severe client distress as a logical response to developmental history. Included are specific suggestions for positive case management and practice. Special attention is given to the interface of multicultural issues, etiology, and treatment. The authors maintain that if professional counselors take a developmental approach to a so-called disorder, the positive theoretical and psychoeducational integrity of the American Counseling Association can be maintained while working with the most difficult issues.     

Fragmenting pictures on the apple macintosh computer for experimental and clinical applications

A set of procedures implemented in Microsoft BASIC is described that creates fragmented versions of pictures scanned into the Apple Macintosh, stores them as resource files, and presents them in a computerized perceptual memory test. A total of 150 pictures were selected from the Snodgrass and Vanderwart (1980) set for fragmentation. The perceptual memory test provides for five forms of 30 pictures each, divided into two sets of 15 that serve alternately as the training or old set and the new set. A training set of 15 pictures is presented for identification during the first (training) phase of the test. The second (test) phase presents the training pictures again, randomly mixed with 15 new pictures for identification. The performance of 100 subjects on the memory test is presented, along with results for each form. Overall, subjects showed improvement on the task with practice (skill learning), indexed by a decrease in thresholds from the training set to the new set. Subjects also showed large savings for the repeated pictures (perceptual learning), indexed by a decrease in thresholds from the new to the old set.     

Adaptation to telestereoscopic viewing measured by one-handed ball-catching performance

A one-handed ball-catching task was used to study the disturbance of depth judgement induced by telestereoscopic viewing (ie viewing with increased effective interocular separation), the recovery of performance with experience in the telestereoscope, and the errors that subsequently arose when the telestereoscope was removed. The ball's trajectory was variable so that subjects had to control both the position and the timing of the grasp in order to catch the ball. On first wearing the telestereoscope, subjects closed the hand when the ball was approximately twice as far away from the eyes as the hand was. After fewer than twenty trials in the telestereoscope subjects were closing the hand at approximately the correct time and place, although rather more trials were needed for ball-catching performance to recover to normal. When the telestereoscope was removed there was an aftereffect, with subjects making the opposite errors to when they began the task. The existence of an aftereffect shows that the process of adaptation involves reevaluation rather than neglect of the misleading binocular information. Helmholtz's theory that telestereoscopes cause the world to be perceived as a scale model is considered. Initial misreaching is roughly consistent with this theory, but there are insufficient data to test it rigorously. Data from the aftereffect phase are clearly inconsistent with the theory. The results confirm the importance of binocular information in dynamic motor tasks, such as ball catching.     

Some relationships between behavioral and traditional assessment

Psychometric principles and procedures were developed within the context of traditional approaches to assessment. In order to illustrate the frequent, if not uniform, applicability of these principles to behavior assessment, we first discuss the differences and similarities between traditional and behavioral assessment. We then point out ways in which, given the nature of behavior assessment, attention to certain psychometric principles and procedures would expedite the development of more adequate behavior assessment devices and procedures.     

Pornography use and sexual aggression: the impact of frequency and type of pornography use on recidivism among sexual offenders

In this study, we examined the unique contribution of pornography consumption to the longitudinal prediction of criminal recidivism in a sample of 341 child molesters. We specifically tested the hypothesis, based on predictions informed by the confluence model of sexual aggression that pornography will be a risk factor for recidivism only for those individuals classified as relatively high risk for re-offending. Pornography use (frequency and type) was assessed through self-report and recidivism was measured using data from a national database from the Royal Canadian Mounted Police. Indices of recidivism, which were assessed up to 15 years after release, included an overall criminal recidivism index, as well as subcategories focusing on violent (including sexual) recidivism and sexual recidivism alone. Results for both frequency and type of pornography use were generally consistent with our predictions. Most importantly, after controlling for general and specific risk factors for sexual aggression, pornography added significantly to the prediction of recidivism. Statistical interactions indicated that frequency of pornography use was primarily a risk factor for higher-risk offenders, when compared with lower-risk offenders, and that content of pornography (i.e., pornography containing deviant content) was a risk factor for all groups. The importance of conceptualizing particular risk factors (e.g., pornography), within the context of other individual characteristics is discussed.
