Self-Reported Delinquency,neuropsychological deficit,and history of attention deficit disorder

This study was designed to evaluate the possibility that a pattern of cognitive deficit is associated with delinquent behavior, while avoiding some of the methodological problems of previous research. The Self- Report Early Delinquency instrument and a research battery of neuropsychological tests were administered blindly to an unselected cohort of 678 13- year- olds. Because the diagnosis of attention deficit disorder (ADD) was found at markedly elevated rates in the backgrounds of these delinquents, the possibility was examined that the neuropsychological deficits of delinquents might be limited to delinquents with histories of ADD. Although delinquents with past ADD were more cognitively impaired than non-ADD delinquents, both groups scored significantly below nondelinquents on verbal, visuospatial, and visualmotor integration skills. In addition, ADD delinquents scored poorly on memory abilities. Subjects with ADD who had not developed delinquent behavior were not as cognitively impaired as ADD delinquents, suggesting that it is the specific comorbidity of ADD and delinquency that bears neuropsychological study.This work was supported by USPHS Grant 1 R23 MH-42723-01 from the Antisocial and Violent Behavior Branch of the National Institute of Mental Health.

Poverty,state, and the family: A challenge for family therapy

Much family therapy writing has focused on work with discrete presenting problems in circumscribed clinical practice settings. This paper takes a broader focus of poor families which do not fit easily into the one-hour therapy schedule, in the context of the powerful forces of politics and economics. If the prevailing political attitudes and economic realities are ignored, direct practice with families may fail to meet them at their point of experience. Examples of political views, and therapeutic and research thinking which do not pay attention to these aspects, are used to highlight the author's point of view.     

The relationship of extraversion,neuroticism, and sensation-seeking to questionnaire-derived measures of nervous system properties

Five obliquely rotated factor analyses were performed on items from Eysenck and Eysenck’s (1975) EPQ, Zuckerman’s (1975) Sensation-Seeking Scale, and Strelau’s (1972) temperament inventory (STI), administered to 277 subjects (Ss). The analyses were used to examine the relationships between the personality dimensions E, N, L, P and Sensation-Seeking, which pertain mainly to social situations, attitudes and feelings, and questionnaire-derived measures of nervous system properties, which, while validated on experimental indices of nervous system properties derived from Nebylitsyn’s (1972) model, are expressed as characteristic features of social behavior, work style and activity. Four factors were identified—extraversion/strength of excitation/mobility; self-control of affect/stability/caution; strength of inhibition/verbal control/motor expressiveness/ nonmanipulativeness; and sensation-seeking/nervousness. The results offer support for Eysenck’s claim of some identity between excitatory strength and E, for the reported relationship between E and mobility, and for Eysenck’s conditioning postulate. They also suggest that similar temperamental variables underlie individual differences in both social and occupational/motor activity. Since Strelau’s STI items are validated on experimental indices of nervous system properties, it follows that typological characteristics may be inferred from questionnaire data derived from both behavioral categories.     

Effects of Fixed-Time Reinforcement Delivered by Teachers for Reducing Problem Behavior in Special Education Classrooms

The effects of fixed-time (FT) reinforcement schedules on the disruptive behavior of 4 students in special education classrooms were studied. Attention provided on FT schedules in the context of a multiple-baseline design across participants substantially decreased all students’ challenging behavior. Disruptive behavior was maintained at levels lower than baseline throughout reinforcement thinning and follow-up phases. The results extend existing literature on the use of FT schedules of reinforcement and provide evidence that FT schedules of reinforcement can be practical to implement in special educational classroom settings.     

Sahlqvist Correspondence for Modal mu-calculus

We define analogues of modal Sahlqvist formulas for the modal mu-calculus, and prove a correspondence theorem for them.
