Frequency of neurologic-psychiatric findings in the late phase following minor and medium severe blunt craniocerebral injuries

The authors present a short review of the pertinent literature and report on their own neuropsychiatric findings following internal craniocerebral injuries, at the same time drawing attention to the necessity of psychological examination. Statistical comparisons with the international literature are complicated owing to the different classifications used for craniocerebral injuries.     

Interpersonal attraction,social identification and psychological group formation

Two perspectives on the nature of the social group and psychological group formation are discussed. The traditional social cohesion approach traces group formation to processes of interpersonal attraction, while the social identity approach defines the group in cognitive terms and considers identification, or self-categorization, to be the mechanism of psychological group formation. On the basis of an experiment by Turner, Sachdev and Hogg (1983) it is hypothesized that interpersonal attraction (positive or negative) is related to group formation only in so far as it enhances intergroup distinctiveness. This hypothesis is experimentally tested in a 2 × 3 (interpersonal liking/disliking per se versus no explicit categorization/random categorization/criterial categorization on the basis of affect) factorial design employing the ‘minimal group’ paradigm. People who like each other and were not explicitly categorized formed a group. This effect was enhanced by criterial categorization but disappeared when categorization was random. Although the results do not support the hypothesis, they are not explicable in social cohesion terms. A social identity explanation is furnished—attraction influences group formation by acting, under certain specifiable conditions, as a cognitive criterion for common category membership. This explanation is located in current theorizing and is proposed as part of a reconceptualization of the relationship between interpersonal attraction and group formation.     

Symbolic comparisons with and without perceptual referents: Is interval information used?

In an attempt to investigate the range effect obtained by Moyer and Bayer (1976), two groups of subjects were taught to associate colors with circles that differed in size by larger or smaller intervals and then participated in a symbolic comparison task, in which they determined which of two simultaneously presented symbols (the first letters of two colors) represented the larger magnitude. A third group of subjects, who merely learned an arbitrary ordering of the colors along the dimension of size, also participated in the symbolic comparison task. Despite the fact that no practice trials were given, there was no effect of interval size in either early or late blocks, and the circle-learning groups did not differ in performance from the group who only learned an arbitrary ordering of colors, even when pairs containing end terms were removed from the analysis. It is concluded that subjects do not use analogue codes in symbolic comparison tasks involving small, repeated sets of arbitrarily defined symbols.     

Social Motives and Susceptibility to Disease: Stalking Individual Differences In Health Risks

This article reviews studies on the relation between social motives and susceptibility to physical illness. The motives examined in the studies include power motivation and affiliation motivation and their related syndromes such as inhibited power and relaxed affiliation. The subject populations include college students as well as adults. Blood pressure, self-reports of illnesses, catecholamines, and parameters of immunologic functioning are among the indices of health outcomes investigated. Taken together, these studies suggest that social motives may be importantly related to susceptibility to illness, that the power motive may be related to heightened susceptibility to illness, particularly when the person is under stress, whereas the affiliation motive may be related to diminished susceptibility to illness.     

Certifying Juveniles for Adult Court: An Attribution Analysis1

Certification is the process whereby older juveniles who have committed felony offenses are transferred from juvenile courts to adult courts. The present study examined the variables that influence decisions in these cases and used attribution theory to conceptualize the process. Data were obtained from files of 150 youths on whom certification petitions had been filed from January 1981 to October 1984. Of these, 125 had been certified and 25 had not. The sample comprised 148 males and 2 females. Data included seriousness of the offense, previous offenses, potential for aggressiveness, level of involvement in the offense, age, court in which the case was heard, year in which the case was heard, IQ, family income and sex. Level of involvement, seriousness of the offense and potential for aggressiveness had the strongest association with certification outcomes, with those high on these measures significantly more likely to be certified. The cluster that predicted outcomes best included level of involvement, seriousness of the offense, potential for aggressiveness, IQ, year in which the case was heard, court in which the case was heard, sex and previous offenses. The most explicitly behavioral variable—how actively the child participated in the offense—was the best single predictor of outcomes.     

Generalised anxiety: A controlled treatment study

The effects of anxiety management training were evaluated by allocating 66 generally anxious clients to either a wait list condition, non-directive counselling, or a combination of relaxation and brief cognitive therapy. Anxiety management was significantly more effective than the wait list condition on a number of relevant measures at post-treatment, but there were relatively few differencs between anxiety management and non-directive counselling, either at post-treatment or at 6 months follow-up. Those differences which were found could plausibly be explained in terms of the demand characteristics of training in relaxation or cognitive therapy. It was concluded that anxiety management is clearly better than a non-treatment control condition, but that its superiority to plausible alternatives which lack the specific components thought to be responsible for improvement has yet to be demonstrated.     

Electromagnetic articulography: use of alternating magnetic fields for tracking movements of multiple points inside and outside the vocal tract

The purpose of this paper is to present a new electromagnetic device which uses alternating magnetic fields for tracking movements of multiple points inside and outside the vocal tract. It is biologically safe, noninvasive, it does not interfere with speech movements, allows for multiple recording in the same subject, and for easy collection of large amounts of data. It is especially suitable for evaluation of patients with speech motor impairments.
