Timing and motor control in clumsy children

The study examined timing control in clumsy children and employed the Wing-Kristofferson (1973) model of repetitive movements in an attempt to identify the locus of timing control difficulties in clumsy children. Two groups of children classified as normal and clumsy (ages 6-7 and 9-10) performed tapping and perception of duration and loudness tasks. Results indicated that clumsy children were significantly more variable than normal children in maintaining a set rate of tapping and in accurately judging time intervals. Evidence indicated that the source of timing control problems in clumsy children may be in a central timekeeping mechanism, possibly the cerebellum.     

Personality and Health: Advantages and Limitations of the Five-Factor Model

Interest in the association between personality characteristics and physical health has been renewed in recent years. Theory and research in this area has also been complicated by conceptual and methodological limitations. The present article briefly reviews this literature and discusses the advantages and limitations of the five-factor model of personality as an integrating framework for studies of personality and health. The model has already been fruitfully applied in several contexts, and more possibilities exist. Although it has some potential limitations, the application of the five-factor model--as well as other aspects of current personality theory and research--is likely to facilitate progress in the study of how personality influences health.     

Measuring drinking patterns among college students.

Alcohol use among college students is of interest to clinicians and researchers. The results of such studies depend on the quality and nature of the measures used. The literature includes a wide variety of operational definitions of drinking patterns, making difficult comparisons across studies. For 109 men and 83 women attending college this paper provides data on the Drinking Practices Questionnaire, a self-report measure of drinking patterns designed specifically for use with college students. The three subscales, Negative Affect, Positive Expectancies, and Negative Consequences, have good internal consistency reliabilities, and scores correlate significantly with measures of problems associated with alcohol use. Appropriate uses of the measure are discussed.     

Is Hume's shade of blue a red herring?

The existence of an idea of a missing shade of blue contradicts Hume's first principle that simple ideas all derive from corresponding simple impressions. Hume dismisses the ‘exception’ to his principle as unimportant. Why does he do so? His later account of distinctions of reason suggests a systematic way of dealing with simple ideas not derived from simple impressions. Why does he not return to the problem of the missing shade, having offered that account? Several suggestions as to Hume's solution of the problem of the missing shade (not all appealing to distinctions of reason) are explored with an eye both to their adequacy as Humean solutions and their value as clues to his dismissal of the problem. Hypotheses concerning the latter perplexity are formulated and discussed as well. Senses in which the missing shade of blue is or may be a red herring are identified. In course, this author names Hume's missing shade ‘marjorie grene’. Historians of philosophy will want to adopt this nomenclature.     

The application of prospective strategies to family therapy

Among the most frequently used theoretical orientations for administering family therapy are the systems, interactional, structuralist, problem-centered, and attachment approaches. Each of these methods proposes a theory concerning the etiology and resolution of conflict, a protocol of assessment, and a view on the therapist's role in advocating intervention techniques. Despite the success of these methods, however, families often leave treatment lacking the interpersonal skills for predicting potential conflict and for overcoming episodes of transition. This paper explores how the prospective approach may rectify this problem by enhancing the family members' use of intuition for experiencing transition and predicting upcoming change. As such, the application of the prospective technique may be beneficial for strengthening family relationships.     

Changes in stereotyped central motor patterns controlling vocalization are induced by peripheral nerve injury.

Adult male zebra finches (Taeniopygia guttata), as closed-ended learners, normally crystallize their songs at 90 days of age, and the song remains fixed throughout life (Price, 1979). We show that injuring the tracheosyringeal nerve(s) (each of which innervates the ipsilateral half of the syrinx, the avian vocal organ) results in a short-term deficit in the syllables forming adult male song; this deficit disappears after ts nerve regeneration. However, when adult males were followed for a period of several weeks after unilateral tracheosyringeal nerve injury, long-term changes occurred in the temporal patterning of song. Syllables were deleted, remaining portions of the song were linked, and new syllables were added. Syllables with call-like morphology were less likely to be deleted from and more likely to be added to the song. Deletions were most often contiguous chunks of syllables. Changes in the temporal patterning of song occurred during specific periods following nerve injury, were completed within 100 days after nerve transection, and were not dependent upon regeneration of the ts nerve. The resulting newly formed song patterns were stable, remaining unchanged up to 1 year later. The ability of adult male zebra finches to make specific types of changes to crystallized song indicates that some form of vocal plasticity remains even after song learning is completed, though this plasticity may be restricted to a subset of song characteristics. The limitations on the types of changes that are possible may reflect how song is centrally organized.     

The Portrayal of Aggression on North American Television1

The past decade has seen an accumulation of evidence that TV viewing influences beliefs about social reality, particularly in areas related to violence. Detailed content analyses of the portrayal of aggression on North American television were conducted in an attempt to document some of the symbolic messages in television content and the extent to which those messages vary according to program category. The TV sample analyzed consisted of 109 programs (81 hours) chosen on the basis of audience viewing figures; 76% were produced in the U.S.A. and 22% in Canada. An average of 9 acts of physical aggression and 7.8 acts of verbal aggression per program hour were observed, but both type and rate of aggression varied by program category. Other methods of conflict resolution occurred rarely, and few witnesses sought alternatives to aggression. Less than 2% of the aggression observed was accidental, and most (69%) was incidental to the plot. Aggression, especially verbal abuse, was often portrayed as humorous, and there was little evidence of consequences. Some differences between Canadian and U.S. programming were noted. The possibility of using schema theory to understand the role of television in the development of beliefs about social reality is explored.     

Family therapy for the borderline patient

Family therapy can be an appropriate modality of treatment for borderline patients: family sessions may be helpful in making order out of chaos in the system. It also takes into account the fear of separation and other developmental issues which are of concern to the borderline patient. Issues related to the structure and format of sessions in the beginning and middle phase of therapy are discussed. Progress and treatment implications including transference reactions are examined. We have concluded that the family members in a case presented have become considerably stronger and more independent. Their current developmental level indicates that we can begin to work on intrapsychic factors.     

The relative error magnitude in three measures of change

Formulas for the standard error of measurement of three measures of change—simple difference scores, residualized difference scores, and the measure introduced by Tucker, Damarin, and Messick—are derived. Equating these formulas by pairs yields additional explicit formulas which provide a practical guide for determining the relative error of the three measures in any pretest-posttest design. The functional relationship between the standard error of measurement and the correlation between pretest and posttest observed scores remains essentially the same for each of the three measures despite variations in other test parameters (reliability coefficients, standard deviations), even when pretest and posttest errors of measurement are correlated.     

Adolescent loneliness

The purpose of this study was to investigate the phenomenon of loneliness in delinquent adolescents with regard to types of delinquency offenses committed, demographic characteristics, and personality characteristics in the areas of interpersonal needs for inclusion, control, and affection. The types of delinquency offenses were categorized as burglary, runaway, drugs, assault, and incorrigible. The demographic variables examined were age, sex, race, family rank or birth order, family structure in terms of parental presence, family income level, religion, and geographic locale. A sample of 98 adolescents was obtained from juvenile detention facilities in three metropolitan areas in the United States. Subjects ranged in age from 12 to 18. Subjects were asked to complete the Loneliness Questionnaire as a self-reported measure of loneliness. Subjects also provided information about themselves relative to demographic characteristics and completed the FIRO-B Questionnaire, which measured interpersonal needs for inclusion, control, and affection. The results revealed no significant differences with regard to any of the demographic variables when the effect of each was considered alone. However, there was a significant effect on loneliness by income when considered jointly with other demographic variables. Adolescents from the middle income group expressed more loneliness than those from the upper and lower income groups. No significant differences were observed with regard to personality characteristics related to interpersonal needs for inclusion and affection, but delinquent adolescents with medium to high needs for control indicated significantly more feelings of loneliness than delinquent adolescents with low needs for control.
