Tigers are something else: A case for family play

This paper is an attempt to bridge the two worlds of family therapy and filial play therapy, introducing the complementary idea of play in therapy. Family play therapy challenges the idea that play is only useful in the treatment of children. Clinical examples are given and uses of play are discussed, including evaluation, play as a therapeutic tool, and the development of themes. The authors believe that therapists who are willing to be playful offer their clients a new world of therapeutic experiences.     

Effects of sex-linked situations and sex composition on cooperation and style of interaction

One hundred and sixteen undergraduates were randomly assigned to same-sex and mixed-sex dyads. They interacted face-to-face in four different role-playing situations, half of which were female linked and half male linked. These situations were structured to give the participants mixed motives toward each other. Results indicate that sex composition and sex appropriateness of the situations affected the style of interaction more than cooperation. In both the same- and mixed-sex dyads, division of task and maintenance between group members occurred. In mixed-sex dyads, males were task oriented, and females maintenance oriented; presumably, sexual identity was used to make this division. In the same-sex dyads, the distribution of task and maintenance behaviors was worked out in the interaction. Participants rated themselves more knowledgable and were more competitive in female-linked situations than in male-linked ones. Under the conditions of the experiment, sex of the participant and sex composition of the dyad were not found to affect cooperation.     

Invention and discovery among the sciences: a P-technique factor analysis

This paper explores how discoveries and inventions in nine scientific disciplines cluster over time in Western culture. The transhistorical sample consisted of 12,761 major scientific contributions tabulated into 44 time-units (full, half, and quarter centuries) extending from 800 B.C. to 1900 A.D. A factor analysis was executed on the correlations among the nine measures after partialing out third-order polynomial time trends. Three orthogonal factors appeared: concrete (chemistry, physics, and biology), abstract (astronomy and mathematics), and applied (technology, geography, and geology) clusters. Medicine loaded moderately on the concrete and abstract clusters. Three types of explanations were discussed-personological, interpersonal, and sociocultural-with suggestions for how they might be tested.     

Applying an occupational classification to the work histories of young men and women

Holland's occupational classification was used to analyze the work histories of a national representative sample of young men and women ages 14 through 24. Hypotheses tested were concerned with the psychological orderliness of occupational changes, the relationship between occupational experiences and aspirations, and the relationship between consistent occupational codes and the stability of work histories. The analyses supported the usefulness of the occupational classification for organizing the work histories of both young men and young women. For both sexes, the classification reflected regular patterns of job changes. The category of a person's earlier job was an efficient predictor of a person's subsequent jobs; likewise, the category of a person's current job forecasted the category of his vocational aspiration. The consistency of an occupational code was also related to job stability for whites but not for blacks.     

The compensation for movement-produced changes of object orientation

When one moves forward, one views objects to the side of one’s path successively from different directions. In the mover’s visual field, such objects change their orientation; relative to him they undergo a partial rotation. Although this rotation is given in several ways, it is hardly ever perceived. This is due to a compensating process that takes O’s change in position relative to the object into account. We demonstrated the existence of this compensating process and measured the accuracy with which it operates by means of a device that made an object turn in response to O’s position change so that the normal rotation of a stationary object relative to the moving O could be augmented or diminished to various degrees.     

The DSM-III and pastoral practice

This essay provides a conceptual bridge between psychiatry and pastoral practice which may facilitate cooperative efforts. The conceptual link is the theological and psychiatric answer to the question, “What is personhood?” found in the biblical doctrine of personhood and theDiagnostic and Statistical Manual of Mental Disorders, 3rd Edition. The essay argues that both views are holistic, compatible, and provide a base for cooperative effort.     

The sausage machine: A new two-stage parsing model

It is proposed that the human sentence parsing device assigns phrase structure to word strings in two steps. The first stage parser assigns lexical and phrasal nodes to substrings of roughly six words. The second stage parser then adds higher nodes to link these phrasal packages together into a complete phrase marker.This model of the parser is compared with ATN models, and with the two-stage models of Kimball (1973) and Fodor, Bever and Garrett (1974). Our assumption that the units which are shunted from the first stage to the second stage are defined by their length, rather than by their syntactic type, explains the effects of constituent length on perceptual complexity in center embedded sentences and in sentences of the kind that fall under Kimball's principle of Right Association. The particular division of labor between the two parsing units allows us to explain, without appeal to any ad hoc parsing strategies, why the parser makes certain ‘shortsighted’ errors even though, in general, it is able to make intelligent use of all the information that is available to it.     

Visual angle and the word superiority effect

Two experiments are reported in which a word superiority effect is obtained under conditions where a fixed set of alternatives are employed with positional certainty as to the critical letter, trial type (word or nonword) is mixed, and the subject is told to fixate the position of the critical letter. A third experiment employed the same methodology except for the fact that the stimuli subtended a larger retinal angle. No word superiority effect was observed in the third experiment. It is suggested that the visual angle of the stimulus display is a crucial factor in experiments on the word superiority effect.
