Assessing violence risk in Tarasoff situations: a fact-based model of inquiry.

Although significant advances in risk assessment research and practice have been made in recent years, there has not been any analysis in the professional literature regarding how and whether the emerging practice recommendations apply in Tarasoff-type situations. We suggest that, when faced with a Tarasoff-type situation, the appraisal of risk should be guided by a method that is primarily fact-based and deductive, rather than by the more inductive risk assessment approach for general violence recidivism, which is guided primarily by base rates and historical risk factors. We review the principles underlying a fact-based, or threat assessment, approach and outline six areas of inquiry that can guide the appraisal of risk: A-attitudes that support or facilitate violence, C-capacity, T-thresholds crossed, I-intent, O-other's reactions, and N-noncompliance with risk reduction interventions.     

Classwide Peer Tutoring: Effects on the Spelling Performance and Social Interactions of Students with Mild Disabilities and Their Typical Peers in an Integrated Instructional Setting

The effectiveness of Classwide Peer Tutoring (CWPT) to enhance the spelling performance and social interactions of three typical students and three students with mild disabilities was investigated. The classroom ecology was measured using the New Code for Instructional Structure and Student Academic Response (NCISSAR). Social interactions were assessed using the Multiple Option Observation System for Experimental Studies (M.O.O.S.E.S.). Spelling performance was measured by weekly pre-posttests. Using an ABAB single-subject design, results indicated that CWPT resulted in: (a) gains in the spelling accuracy of all students (up to 49%), (b) increases of students' duration of positive social interactions (up to 86%), and (c) high satisfaction ratings for both the students and the teacher. Comparisons between typical students and students with mild disabilities during CWPT suggested no differences in their duration of social interactions. Furthermore, the mean spelling accuracy of the students with mild disabilities was comparable to the spelling accuracy of the typical students (91% vs. 96%, respectively). Implications of the findings for the inclusion of students with mild disabilities in general education settings are discussed.     

Changes in self-esteem during the middle school years: a latent growth curve study of individual and contextual influences

Hierarchical linear modeling (HLM) techniques were used to explore interactions among individual and contextual variables and their effects on initial self-esteem levels and changes in these levels across the three years of middle school in a large, diverse sample (N=1804 students attending 23 schools). Interactions among race, social class, school socioeconomic status (SES), and contextual congruity were found to be particularly influential. Low-income European-American youth consistently experienced the lowest self-esteem levels and the sharpest declines during middle school. Social incongruity appears to play a crucial role in predicting such losses. These results highlight the need for further research employing similar techniques to explore how individual and contextual factors affect the development of self-esteem over the middle school years.     

Assessment of Psychotic Disorders in Inpatient Children and Adolescents: Use of the Devereux Scales of Mental Disorders

The Devereux Scales of Mental Disorders (DSMD), with its 3-factor model of measurement (i.e., Internalizing, Externalizing, and Critical Pathology), may be useful in screening for psychotic disorders in children. This study assessed the ability of the DSMD to differentiate between inpatient children and adolescents with psychotic disorders (n = 18) and those with other clinical syndromes (n = 71). Results of ANCOVAs indicated that the psychotic group scored significantly higher on most DSMD scales and composites than the nonpsychotic clinical group. However estimates of effect size were particularly large for the Critical Pathology Composite and the Autism and Acute Problems Scales. Diagnostic efficiency statistics revealed that the DSMD's Critical Pathology Composite was highly accurate in differentiating between the 2 clinical groups. These findings support the utility of the DSMD in identifying children and adolescents with psychotic disorders.

A study of syntactic processing in aphasia I: behavioral (psycholinguistic) aspects

This paper presents the results of a study of syntactically based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control participants. We measured off-line, end-of-sentence, performance (accuracy and reaction time) in two tasks that require comprehension--enactment and sentence-picture matching--and in grammaticality judgment, with whole sentence auditory presentation. We also used sentence-picture matching and grammaticality judgment as tasks in two self-paced listening studies with the same patients to measure on-line performance. In each task and presentation format, we presented sentences that tested the ability to assign and interpret three structural contrasts chosen to examine different basic syntactic operations: actives and passives, subject and object extracted relative clauses, and reflexive pronouns and matched sentences without these elements. We examined these behavioral data to determine patterns of impairment in individual patients and in groups of patients, using correlational analyses, factor analyses, and analyses of variance. The results showed that almost no individual patients had stable deficits referable to the ability to interpret individual syntactic structures, that a variety of structural features contributed to sentence processing complexity both on-line and off-line, that correct responses were associated with normal on-line and errors with abnormal performance, and that the major determinant of performance is a factor that affected performance on all sentence types. The results indicate that the major cause of aphasic impairments of syntactically based comprehension are intermittent reductions in the processing capacity available for syntactic, interpretive, and task-related operations.     

A study of syntactic processing in aphasia II: neurological aspects

This paper presents the results of a study of the effects of left hemisphere strokes on syntactically-based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control subjects for the ability to assign and interpret three syntactic structures (passives, object extracted relative clauses, and reflexive pronouns) in enactment, sentence-picture matching and grammaticality judgment tasks. We measured accuracy, RT and self-paced listening times in SPM and GJ. We obtained magnetic resonance (MR) and 5-deoxyglucose positron emission tomography (FDG PET) data on 31 patients and 12 controls. The percent of selected regions of interest (ROIs) that was lesioned on MR and the mean normalized PET counts per voxel in ROIs were calculated. In regression analyses, lesion measures in both perisylvian and non-perisylvian ROIs predicted performance. Patients who performed at similar levels behaviorally had lesions of very different sizes, and patients with equivalent lesion sizes varied greatly in their level of performance. The data are consistent with a model in which the neural tissue that is responsible for the operations underlying sentence comprehension and syntactic processing is localized in different neural regions in different individuals.     

Effect of relaxation on working memory and the Bispectral Index of the EEG

Beneficial effects of relaxation on cardiovascular and immune functions and on memory has been implied but an empirical relationship between task performance and anxiety reduction has not been reported. In this study, we investigated whether guided imagery of relatively short duration would decrease S-Anxiety and electroencephalogram Bispectral Index and improve working memory. 42 participants (age: M=39, SD=11, 14 men, 28 women, university students and VA Medical Center employees, recruited by their professor or by fellow employees) underwent relaxation by 16-min. guided imagery or no treatment (control). Spielberger's State-Trait Anxiety Inventory and the WAIS-III Letter-Number Sequencing Test were administered before and after relaxation. S-Anxiety and BIS Index decreased and the Letter-Number test score increased by 30% after relaxation but not in the control group. This score was higher for participants with low anxiety and BIS Index. There was no significant difference between the groups before treatment. The results suggest that guided imagery of short duration produces relaxation as measured by psychological and neurophysiological indices and improves working memory performance.
