A comparison of MMPI profiles of heroin addicts based on multiple methods of classification

MMPI profiles of 442 male narcotic addicts in a drug treatment program were classified according to one of three methods: (a) highest 2-point code, (b) cluster analysis, and (c) concordance with common actuarial rules of profile fit. Profiles were then compared with those previously reported in the research literature. While each method resulted in slightly different perspectives, each reported modal profiles analogous to the 49'/94', 42'/24', and 48'/84' profiles. A frequency table of 33 different profiles by rates per thousand were presented as prototypal base rates for future comparison.     

Sex differences in problems related to depression

The study investigated possible sex differences in the types of problems that are correlated with Beck Depression Inventory (BDI) scores, using a sample of college students. Problems related to assertiveness and feeling ill at ease were positively correlated with BDI scores for males, but not for females. In contrast, conflicts with parents, feelings of being boxed in and of boredom, lack of money, and chronic physical complaints were positively related to BDI scores for females, but not for males.     

Variables related to reported learning in brief experiential groups held at professional meetings

Reports of learning from 119 participants of 18 general psychodynamic groups from the 1981 and 1982 annual meetings of the Canadian Group Psychotherapy Association were investigated. Two main learning factors emerged from a factor analysis of participant ratings, learning about oneself in a small group (factor one) and learning how to be an effective leader with professional skills (factor two). Participants reported moderate to considerable learning for both factors even though the stated task of the groups did not emphasize the learning of professional skills. Relationships between several classes of variables (group, leader, demographic) and reported learning were studied. Results that were consistent with several previous investigations were found. The discovery of a participant, sex-difference finding, i.e., greater reported learning by the women, generated a number of questions that may be addressed in future investigations.This article was derived from a paper presented at the Fourth Annual Meeting of the Canadian Group Psychotherapy Association, October 27, 1983, Banff, Canada.     

Do letter features migrate? A note of caution

Summary The feature-integration model of visual information processing (Treisman & Gelade, 1980) predicts perceptual errors based on the incorrect grouping of stimulus features in multi-element displays. Experiment 1 examined the frequency of such errors with a tachistoscopic bar probe task using letters and novel patterns with a production response. A substantial proportion of the errors did involve figures that were not present in the display but contained combinations of features which had been present. Such errors were especially prominent with novel patterns. The results with letters suggested that such responses were due to guessing, not feature migration, and this was confirmed by Experiment 2. In the second study, responses were collected for single character displays but were scored as if they had been responses to the multielement displays in Experiment 1. The results showed the same high proportion of illusory conjunction errors as the previous results and it was concluded that both results were due to guessing. Spatial confusions in the bar probe task with letters appear to involve whole characters, not character features.This research was supported by grant A-9581 from the National Science and Engineering Council of Canada to the senior author. This research was reported as a paper to the annual meeting of the Canadian Psychological Association, Toronto, 1981. Ian Morrison is now a post-doctoral fellow at the Department of Psychology, Carnegie-Mellon University.     

Scaling of output regularities in free recall: A review

Problems involved in scaling the output regularities observed in free recall are outlined, and assumptions underlying attempted solutions for both categorized and “unrelated” lists are discussed. Several studies that make claims for the superiority of particular measures have indeed demonstrated that it matters which index is selected, but they are shown to provide no justification for preferring one to another. Evidence from simulation studies, however, suggests that a number of measures have “built-in” correlations with theoretically relevant variables such as recall. Some of these biases have proved elusive because their appearance is confined to nonrandom output sequences. The relation between theoretical assumptions and simulation studies is discussed.     

The case for praxics

Since the early 1900s a variety of names has been proposed for the scientific study of behavior, but none has come into general use. "Praxics," a recent entry, is defensible on several grounds. "Behaviorism," on the other hand, is the name of a school of philosophy. Though praxics has roots in behaviorism, the term "behaviorism" should not be applied to praxics. Confusion between the science and the philosophy has retarded the growth of the science immeasurably. Its growth has also been impeded by its association with psychology, which is still primarily the study of mind. Efforts are underway to establish praxics as an independent field.

Perspectives on individual-family-social network interrelations

The author focuses on the trend in the family therapy field toward an expanded view of families in the context of their social environments. Within this broader eco-system perspective attention is given to individual-family-social network interrelations with implications for the family therapist.An earlier version of this paper was presented at the American Association for Marriage and Family Therapy, Dallas, Texas, October 29, 1982. Appreciation is expressed to Alice Lynn for her comments and suggestions on an earlier draft of this paper. The author has also benefitted from discussions with Douglas Sprenkle on paradigms and contexts.
