Teaching young children how to use a computer-based Teletype as a “desk calculator”

The first stage in the research reported here was to teach students the mechanics of how to use a computer-based Teletype as a “desk calculator” in the solution of arithmetic problems. In the second stage, we examined a specific use for the desk-calculator program: we presented a series of word problems to the students and analyzed the solutions of these problems to determine the variables related to problem difficulty.     

A signal detection theory analysis of a category judgment experiment

A category-judgment experiment is the reported. Rating-scale judgments of loudness were made with five or eight intensity levels of a tone and with different frequencies of presentation of the stimuli. Obtained ROC curves for pairs of stimuli were judged to support application of signal-detection theory. However, certain common assumptions of the theory are called into question by the data. Discrimination was poorer when more categories were available. This is attributed to an increase in criterion variance with an increase in the number of criteria. The slope of the ROC curves for different stimulus pairs suggested that stimulus variance is neither constant nor does it necessarily increase with stimulus intensity It is argued that stimulus variance may depend upon the distribution of internal observations over all trials.     

DOMINANCE AND INEQUALITY IN X-RATED VIDEOCASSETTES

Feminists have been concerned about the debasement of women in sexually explicit material. The purpose of this study was to determine the extent of domination and sexual inequality in x-rated videocassettes through a content analysis of 45 widely available x-rated videocassettes. The sample was randomly drawn from a list of 121 adult movie titles widely available in family videocassette rental stores in southern California. Over half of the explicitly sexual scenes were coded as predominantly concerned with domination or exploitation. Most of the domination and exploitation was directed by men toward women. Specific indicators of domination and sexual inequality, including physical violence, occurred frequently. The growth of the videocassette rental industry and the popularity of x-rated films, coupled with the messages these films convey, is a cause for concern.     

The effects of therapist turnover in a training clinic: The core group phenomenon

Group psychotherapy conducted in training settings presents the membership with a unique opportunity to experience and work through loss. This paper describes the potentially problematic influence of predictable therapist turnover in these clinical settings. The core group phenomenon which emerges as a function of this anticipatory grief is described, as are the dynamics of core group members who are particularly vulnerable to the comings and goings of therapists in training. Finally, the importance of therapist attention to the impact of the turnover process in group psychotherapy training programs is underscored.     

Couples psychotherapy group: Treatment of the married alcoholic

As part of an intramural research program of the National Institute of Alcohol Abuse and Alcoholism focused on the psychobiogenetics of familial alcoholism, a psychodynamically oriented married couples psychotherapy group was formed. Its purpose was to determine whether this modality could be utilized as an outpatient treatment approach to identify and modify interpersonal interactions that affect both drinking behavior and the quality of family and marital life. This paper, a clinical case report, presents follow-up data and disusses both themes that emerged in the therapy process and the usefulness of this modality in the treatment of the married alcoholic.She was formerly Chief, Unit of Family Studies, Laboratory of Clinical Studies, National Institute of Alcohol Abuse and Alcoholism (NIAAA).At the time this paper was written, she was a Research Social Worker, Laboratory, of Clinical Studies, NIAAA, Bethesda, Maryland.     

Perceptual learning in visual category acquisition

The attribute structure of a set of dot patterns was studied by having subjects segment (parse) the dots of each pattern into parts or subunits by drawing circles around groups of dots from each pattern. These parsing data were obtained for subjects who had no prior experience with the patterns and for subjects who had previously learned to identify the patterns as members of one of four categories. Analyses of the parsing data indicated that category learning increased the salience of large subunits that were similar in orientation for patterns that were members of the same category. This evidence for perceptual learning was obtained even when the category training procedure required learning to identify the patterns individually, suggesting that attribute abstraction and item learning are not incompatible. It was also obtained without an increase in overall intersubject agreement. The latter result led us to question the usefulness of intersubject agreement as an index of category knowledge.
