Parceling Component Effects of a Multifaceted Prevention Program for Disruptive Elementary School Children

This study examined predictors and outcomes of attendance in two standard components of a multifaceted preventive intervention aimed at children with early-onset disruptive behavior after 3 years of intervention. Mean rate of attendance in the Family Program, but not the Summer School Program, differed by level of child disruptiveness (grouping variable). Although predictors of attendance (SES, single-parent status, child IQ) did not differ across high- and low-disruptive groups, predictors of outcome were moderated by level of child disruptiveness for academic achievement and aggression outcomes, but not for social competence. Higher attendance in the Summer Program was associated with higher child social competence at Year 3 for all children. For academic achievement, higher attendance in the Summer Program was associated with higher scores for mild/moderately disruptive children and lower scores for highly disruptive children in Year 3. Higher attendance in the Family Program was associated with lower aggression scores for mild/moderately disruptive children. Findings highlight the importance of matching intervention components to the assessed or expressed needs of client subgroups.     

Structural Organization of Practice: Effects of Practicing Under Different Informational Constraints on the Acquisition of One-Handed Catching Skill

The question addressed in this study was the effects of the manipulation of the informational constraints of practice conditions on the acquisition of one-handed catching skill. Three groups of poor catchers (8 participants per group) practiced in either a normal-light, ball-only, or interspersed ball-only and normal-light condition (N = 450 trials). All groups exhibited a significant improvement in the number of catches and catching score and a reduction in the number of misses by the end of practice. The structural organization of the practice conditions had a significant effect on catching performance. Practicing in the interspersed condition had a positive residual effect on subjects' performance in normal light. Similarly, there was a positive residual effect of practicing in the ball-only and the interspersed conditions on subjects' normal-light, posttest performance. The findings are interpreted as support for the argument that practicing under varying informational constraints can benefit skill acquisition by directing the subjects' search toward relevant sources of information.     

The Effects of Training on Perceptions of Sexual Harassment Allegations

This study of 176 college juniors examined the effects of respondent gender and sexual harassment training on the perceptions of what constitutes sexual harassment in the workplace. Variation in these perceptions, due to severity of the sexually oriented behavior, was also examined. Regardless of the subject's gender, individuals who 6 weeks earlier had seen a training film about sexual harassment rated severe sexually oriented work behaviors as more harassing than did individuals who had not seen the film. Additionally, males who had not seen the film rated ambiguous sexually oriented behaviors as less harassing than did males and females who had seen the film, and as less harassing than females who had not seen the film. Implications for the importance of training in addressing sexual harassment are discussed.     

Projection, Double Bind, and Demonic Possession: Some Common Elements in Three Theories of Psychosis

A desirable goal in science is to identify points at which theories converge. Three theories of psychosis are addressed with respect to three elements they share. The theories are (1) projection, (2) double bind, and (3) demonic possession. The points of convergence are (1) negative injunction, (2) persecutory belief, and (3) obedience to a transcendental command. Implications of the linkage between the elements and theories are drawn.     

Schreber, Perceval, and Van Gogh: Three Eminent Cases Considered from the Perspective of Four Characteristics of Psychosis

The psychotic dispositions of Schreber, Perceval, and Van Gogh are considered. Four characteristics appear to run through their psychoses, and these are identified and illustrated: (1) Negation, (2) persecutory belief, (3) obedience to a transcendental command, and (4) evangelism/martyrdom. Three of the elements have been identified previously, but evangelism/martyrdom is identified here for the first time. The characteristics tend to move in a linear direction, each reinforcing the psychotic state. Therapy requires a disruption of the path, whether through biochemical or psychosocial means or both.     

The Genetic and Environmental Relationship Between General and Specific Cognitive Abilities in Twins Age 80 and Older

In the first twin study of the old-old, individuals 80 years old and older, we examined the relationship between general and specific cognitive abilities from a genetic perspective. That is, we examined the extent to which genetic and environmental factors influence major group factors of cognitive abilities, independent of general cognitive ability. As part of the OctoTwin project in Sweden, general and specific cognitive abilities were assessed in 52 monozygotic and 65 same-sex dizygotic twin pairs 80 years old and older using a battery of seven tests that assess verbal, spatial, speed-of-processing, and memory performance. Results suggest that genetic effects associated with general cognitive ability ( g ) account for the correlation between g and verbal, spatial, and speed-of-processing abilities. No genetic influences were found for these specific cognitive abilities separate from g . In contrast, memory ability appears to be more distinct genetically from g than are other cognitive abilities. Comparison with younger samples suggests that cognitive abilities relating to speed of processing may be genetically dedifferentiated in the old-old.     

Limbic system dysfunction and inventoried psychopathology among incarcerated pedophiles

This study explored relationships between “highly probable” neuropathology in the limbic system (as gauged by clinically elevated scores on the Limbic System Check-list-33, or LSCL-33, a screening index for limbic system dysfunction developed by medical researchers at Harvard and Dartmouth) and inventoried psychopathology (as gauged through scores on the MMPI) among a group of adjudicated pedophiles incarcerated for treatment in a specialized prison for criminal sexual psychopaths in a mid-Atlantic state. Principal findings: Only 33 percent of this sample of incarcerated pedophiles exhibits scores on the LSCL-33 at a level high enough to warrant a medical conclusion of “probable” limbic system dysfunction. When scores on the MMPI are grouped according to critical values for clinically relevant scores on the LSCL-33, significant F ratios in one-way analyses of variance are observed on L, F, K, Hs, D, Hy, Pa, Pt, Sc, and Ma. Mean T scores for “probable” dysfunctionals simultaneously reach elevations at or above the threshold of clinical significance for Pd, Pa, and Sc. On that basis, the categorization psychopathic paranoid schizophrenia readily applies to limbic system dysfunctional child sexual abusers studied in this inquiry, but not to their nondysfunctional counterparts. But significant F ratios are observed neither for the age of the victim(s) in the instant offense(s), for the number of prior arrests for sex offenses, for the number of prior arrests for any and all felony offenses, including sex offenses, nor for the offender's current age. However, a stepwise multiple regression between gross number of prior arrests for any and all offenses (including sex offenses) as the most robust of the indices of past criminal activity and both LSCL-33 and MMPI scores across all offenders represented in this inquiry (i.e., the limbic system dysfunctional, the nondysfunctional, and a mid-range group) proceeds to four steps, achieving a multiple R of .575 and encompassing Pd, Mf, Pa, and LSCL-33 scores as the most efficient interactive post-dictive set. Stepwise multiple regression analyses of past arrest record computed independently for limbic system dysfunctionals and nondysfunctionals progresses among dysfunctionals to seven steps, achieving a multiple R of .867 and encompassing Pd, Hy, Ma, Mf, Si, Pa, and Sc scores as the most efficient interactive post-dictive set; and among nondysfunctionals, to six steps, achieving a multiple R of .797 and encompassing Mf, D, Pt, Hy, Pa, and over-controlled hostility scores as the most efficient interactive post-dictive set. The latter results are interpreted as suggesting that neuropathology and psychopathology interact with and potentiate each other in post-dicting criminal behavior among the pedophiles studied in this inquiry. This study was supported in part by the Fund for Correctional and Forensic Psychology, Rutgers University Foundation. The investigators express deep appreciation to Charles Albino for assis-tance in data collection.
