A study of neuropsychological impairment among school-indentified learning-disabled students

This investigation examined the proportion of school-identified learning-disabled (LD) students who scored in the impaired range on the Halstead Reitan Neuropsychological Battery for Children (HNBC) over a 20-year period. A difference was noted in findings for periods before and after the passage of federal legislation (Public Law 94-142); specifically, the proportion of LD students who scored in the impaired range on neuropsychological tests was significantly higher prior to than after this law. A similar pattern of impaired performance across the different tests was noted before and after the legislation. The implications of these results for theorists and practitioners are discussed.     

Modifying Beliefs and Attitudes to Exceeding the Speed Limit: An Intervention Study Based on the Theory of Planned Behavior1

This study builds on previous theory of planned behavior (TPB) studies in which we identified the beliefs and values which predict intention to commit driving violations. Four short experimental videos were developed in order to assess the effectiveness of an intervention grounded in the TPB. Three of the videos featured the major constructs of the TPB model. The fourth video featured anticipated regret, an addition to the TPB model which had previously been shown to add significantly to its predictive performance (Parker, Manstead, & Stradling, 1995). Results indicated that two of the videos brought about statistically significant belief changes with respect to scores on TPB items, and significant changes in general attitudes toward speeding. Discussion centers on the problems encountered in operationalizing the TPB constructs and on the potential of theory-based interventions to induce attitude change.     

Dual diagnosis: Clinical issues in the treatment of substance abuse,and affective,personality, and psychotic disorders

Co-morbidity of alcohol and substance with the spectrum of other psychiatric diagnoses is examined with specific emphasis on diagnostic indicators for anxiety and mood disorders. Diagnostic issues for the chemically dependent person are examined with the context of borderline personality disorder, schizophrenia and other psychiatric disorders. Clinical research related to the dually-diagnosed patient is explored     

One-Handed Juggling: A Dynamical Approach to a Rhythmic Movement Task

The skill of rhythmically juggling a ball on a racket was investigated from the viewpoint of nonlinear dynamics. The difference equations that model the dynamical system were analyzed by means of local and nonlocal stability analyses. These analyses showed that the task dynamics offer an economical juggling pattern that is stable even for open-loop actuator motion. For this pattern, two types of predictions were extracted: (a) Stable periodic bouncing is sufficiently characterized by a negative acceleration of the racket at the moment of impact with the ball, and (b) a nonlinear scaling relation maps different juggling trajectories onto one topologically equivalent dynamical system. The relevance of these results for the human control of action was evaluated in an experiment in which subjects (N = 6) performed a comparable task of juggling a ball on a paddle. Task manipulations involved different juggling heights and gravity conditions of the ball. The following predictions were confirmed: (a) For stable rhythmic performance, the paddle's acceleration at impact is negative and fluctuations of the impact acceleration follow predictions from global stability analysis; and (b) for each subject, the realizations of juggling for the different experimental conditions are related by the scaling relation. These results permit one to conclude that humans reliably exploit the stable solutions inherent to the dynamics of the given task and do not overrule these dynamics by other control mechanisms. The dynamical scaling serves as an efficient principle for generating different movement realizations from only a few parameter changes and is discussed as a dynamical formalization of the principle of motor equivalence.     

Relationships among affect in play, interpersonal themes in fantasy, and children's interpersonal behavior

Relationships among children's affective expression in fantasy play, interpersonal themes in projective stories, and concurrent interpersonal behaviors were investigated in 49 children. Participants completed a play task, a projective storytelling task, and a brief IQ measure. Peer and teacher ratings provided measures of interpersonal functioning. Results found that access to and comfort with affect is related to the ability to think in interpersonal ways. Neither affective expression in play nor interpersonal themes in projective stories were related to actual interpersonal behavior.     

Depression and the soul

Clergy are often confronted by challenges in dealing with the depressed congregant. This paper addresses the interface between psychology, psychiatry, and religion in a discussion of two cases. Models are suggested for dealing with the issues raised by the depressed congregant. The paper developed from a symposium on “The Depressed Congregant: Three Pastoral Responses to a Case Vignette” presented at a conference for cleargy onDepression and The Soul, at Temple Sholom in Chicago.     

Partial matching in the Moses illusion: Response bias not sensitivity

Previous research has demonstrated that people have enormous difficulty in detecting distortions in such questions as, “How many animals of each kind did Moses take in the Ark?” Reder and Kusbit (1991) argued that the locus of the effect must be the existence of a partial-match process. Other research has suggested that this partial-match process operates at the word level and that, with adequate focus on the relevant word, the Moses illusion is greatly diminished. The present experimental results argue that those conclusions were based on a shift in response criterion with no concomitant change in ability to detect distortions. Furthermore, the data suggest that the matching process operates below the word level, at the level of distinctive features.     

Features Resembling Tourette''s Syndrome in Developmental Stutterers

Developmental stuttering (DS) may be related to the extrapyramidal motor system and shares many clinical similarities with Tourette's syndrome (TS), which is widely believed to be associated with extrapyramidal dysfunction. Twenty-two stutterers were examined for neuropsychiatric features commonly seen in TS, including tics, obsessive-compulsive behaviors (OCB), and attention deficit disorders. Eleven stutterers displayed motor tics, and symptoms of OCB were observed at rates similar to those seen in persons with TS. Few stutterers demonstrated significant attentional deficits. Findings are consistent with models suggesting extrapyramidal involvement in DS and raise the possibility that DS and TS are pathogenetically related.     

Concordance Between Mothers' and Children's Reports of Somatic and Emotional Symptoms in Patients with Recurrent Abdominal Pain or Emotional Disorders

Mother–child concordance regarding children's somatic and emotional symptoms was assessed in children with recurrent abdominal pain (n = 88), emotional disorders (n = 51), and well children (n = 56). Children between 6 and 18 years of age and their mothers completed questionnaires assessing the children's somatic symptoms, functional disability, and depression. Mothers of children with recurrent abdominal pain reported more child somatic and depressive symptoms than did their children, and mothers of children with emotional disorders reported more child depressive symptoms than did their children. Higher levels of maternal distress were associated with greater mother-child discordance in the direction of mothers reporting more child symptoms than did their children. No significant child age or sex differences were found in concordance patterns.
