Word association and availability of response in an aphasic subject

Confirmation of the claim that verbal responses are elicited more easily in aphasia when the range of possible responses is restricted was obtained by comparing stimulus words from a Word Association Test to which an aphasic subject gave three types of responses and those to which she made no response. Contrary to expectation, words of lower frequency in the language did not present more difficulty as stimuli and were given more often as responses than are such words in the norms. It is suggested that a generative model of semantics may be better able to account for such findings than an interpretive dictionary model.This work was assisted by a grant from the Stroke Research Fund.     

Concept identification with concurrent and delayed verbalization

Concept labelling and use of complex solutions is facilitated by instructions to verbalize concurrently with initial stimulus presentation. Older subjects who delay verbalization until after task completion are less effective in using relevant stimulus dimensions for solution and more closely approximate the performance of younger concurrent verbalizers.     

Temporal order: The effect of single versus repeated presentations,practice, and verbal feedback

Whereas Hirsh and Sherrick (1961) found that experienced Os could judge correctly the temporal order of a sound and a light presented repeatedly when the interval separating them was 20 msec, Hirsh and Fraisse (1964) found that naive Os required about 60 msec for the same accuracy of performance with single presentations of the same pair. This experiment examined the effects of single vs repeated presentations, practice, and verbal feedback on performance in the judgment of temporal order. The results indicate that performance under repeated presentation is significantly better than under single presentation, that learning effects are most pronounced during the first 4 of 16 sessions, and that the effects of feedback appear to depend on the precise wording given the S on how he is to perform.     

An investigation of parental modeling in the etiology of diabetic illness behavior

The role of vicarious processes in the etiology of behavioral reactions to medical illness was examined in a preliminary investigation. Twenty-seven diabetics without chronically ill parents were assigned to an avoidant-model (i.e. parent reported to have generally avoided work and chores when ill) or non-avoidant-model group. Subjects subsequently provided retrospective and current information concerning their illness behavior experiences. Pathophysiology ratings by a blind rater and glycosylated hemoglobin measures were taken. The results indicated that diabetics with an avoidant model terminated work, chores etc. when ill significantly more than non-avoidant-model group subjects. Diabetics with an avoidant model reported significantly higher medical utilization rates, days ill and poorer quality of life. No group differences were observed on pathophysiology rating and glycosylated hemoglobin measures. The results suggest that individual differences in behavioral reactions to similar degree and type of medical pathology may be related to prior learning experiences such as modeling. The need for a reliable and valid assessment methodology to be used in future related research is emphasized.     

Beating the memory drum: Rapid sequential visual presentation (RSVP) on a 4K PDP-8

A program for presenting alphanumeric strings in rapid succession on a Videoterminal is described. Rates of up to 30 items/sec can be obtained with relatively “slow” systems by creating a push-up stack in the terminal’s display memory and scrolling the items past a small display window during presentation. Advantages of such a program are discussed, and the system is compared to mechanical techniques of rapid sequential visual presentation.     

Effects of absolute mask energy and mask energy range on metacontrast suppression

In an experiment similar to one by Bernstein, Fisicaro, and Fox (1976), subjects were asked to judge the brightness of test stimuli in a metacontrast display. The energies of the test and of the mask varied orthogonally. Various experimental conditions differed with respect to the range of mask energies. Individually, the mask energies were generally weaker than the test energies. The results replicated the main findings of Bernstein et al. (1976) in that judgments of the test were negatively correlated with mask energy at short stimulus onset asynchrony (SOA) but positively correlated at long SOA. These effects were more pronounced when the masks were similar in energy range and level to the tests than when they were wider in energy range and weaker. In general, there was no evidence for the effects of trial-to-trial variation described by Hake, Faust, McIntyre, and Murray     

Cross- vs. within-racial judgments of attractiveness

Subjects from two pairs of ethnic groups (Chinese and White in Experiment 1, Black and White in Experiment 2) judged the attractiveness of faces in yearbook pictures of persons that belonged to their own or to the other ethnic group. This was to see whether: (1) a given group would perceive more variation in the attractiveness of faces belonging to its own vs. the other ethnic group, as suggested by the cross-racial literature, for example, Malpass and Kravitz (1969), and (2) the two groups would use the same or different rules to define attractiveness. There were essentially no differences in perceived variation for cross- vs. within-racial judgments, but there were differences in the criteria used to define attractiveness. As expected, Black and White aesthetic criteria were more like one another than were Chinese and White criteria. Discussion centered around reconciling these findings with the recognition literature.     

A family therapist in the People's Republic of China

The author, a psychiatrist, recently visited the People's Republic of China, and reports some impressions about the status of the Chinese family, Chinese psychiatry, and the current use of the family model.     

ABSTRACTS OF LITERATURE

A discussion of family therapy emphasizing the indications for and the goals of this type of treatment. Differences between family and group therapy are presented with the suggestion that group treatments exists for individual improvement and growth and family treatment for improvement of relationships and growth of the family unit.
