Children vulnerable to psychopathology: The Stony Brook high-risk project

The study of children at risk for the development of schizophrenia is a promising research strategy for increasing our understanding of the etiology of schizophrenia. This paper describes the methods and procedures of such an investigation. Three groups of children are being followed: those who have a schizophrenic parent, those who have a depressive parent, and those whose parents have no psychiatric history. There are three major foci of our assessment procedures. First, the patient, spouse, and family environment are examined. Second, the children are assessed in school from the vantage point of both peers and teachers. Finally, the children are tested with several laboratory measures of cognitive processes, attention, emotional responsivity, and social interaction.This research was supported by Grant MH-21145 from the National Institute of Mental Health and by funds from the W.

Laterality effects in judgment of the identity and position of letters: A signal detection analysis

In two experiments subjects received 100 ms tachistoscopic presentations, either to left or right of fixation, of a rectangular matrix of 12 cells. On each trial three cells were filled, each with a different symbol drawn from a set of 12 letters and digits. In one (the “letter” experiment) subjects had to decide whether a particular letter (nominated at the end of the trial) had been one of the three presented. In a second (the “position” experiment) they had to decide whether a cell in the matrix (again nominated at the end of the trial) had been one of those that contained a symbol. Judgments were made on a four-point rating scale, and measures of sensitivity and response bias were calculated. In the letter experiment sensitivity was greater for presentations to right of fixation, and in the position experiment for those to left.     

But can she command a ship? Acceptance of women by peers at the coast guard academy

The integration of women into the military, mandated by legislation in 1976, was problematic at first; several studies suggested that women were not welcomed by their colleagues. Peer acceptance is an important issue for the Coast Guard, since female officers are not officially discriminated against in duty assignments. Results of this current study, which assessed whether or not male Coast Guard cadets' attitudes have changed over time, suggest that males have become more tolerant of the idea of women in the military, and especially, that male cadets' perception of their female peers becomes more positive over time. The results are discussed in terms of Festinger's cognitive dissonance theory.This article is a revision of a paper presented at the 92nd annual meeting of the American Psychological Association, Toronto, Canada, August 1985.     

Speech competence of children vulnerable to psychopathology

Verbal productivity and cohesion and reference patterns of children of schizophrenics (N=23), unipolars (N=43), bipolars (N=38), and normals (N=53) were assessed using the Rochester and Martin (1979) evaluation system. Children of all offspring groups could be discriminated from one another, with children of schizophrenics showing the most deviant speech performance across all dependent measures. Children of schizophrenics were less verbally productive and had poorer patterns of cohesion between ideas than children of normals. In addition, they produced more unclear and ambiguous references to previously mentioned ideas than did children of normals. The consistency of deviance and performance on specific dependent variables in these children at risk for schizophrenia was similar to the speech performance of thought-disordered schizophrenics. Possible explanations for these similarities were discussed and evaluated.This research was supported by grant number MH21145 from the National Institute of Mental Health and by funds from the William T.

The sex-typing of adult and child behavior in toy sales

In order to investigate sex-stereotyping pressure in toy sales, a field experiment was conducted in which students approached 134 sales persons in 67 retail outlets, asking for help in selecting a toy for a niece or nephew, age 5. The results indicated that toy sales advice serves primarily to reinforce traditional sex-role expectations. Overall, salespersons gave more sex-stereotyped than neutral responses, and their responses did not vary by retail setting (specialized vs. department/chain stores) or the age of the salesperson. As expected, more stereotyped responses were received by male than by female buyers, especially when both sought suggestions for a male child. The results were consistent with the hypothesis that salespersons hold stereotyped conceptions of adult socialization practices and channel interaction in ways that behaviorally confirm these stereotypes. A number of other findings are presented and discussed.     

Wundt's psychological experiment in the light of his philosophy of science

Summary Wundt initiated the first systematic psychological research programme. This achievement occurred at the same time as his elaboration of a philosophy of science which was anti-inductivist and stressed the priority of explanatory motives. Specifically psychological explanations depended on concepts of psychological causality as manifested in apperceptive or volitional processes. The major differences between the Wundtian and other models of psychological experimentation can be understood in the light of this general approach. Thus experimenters and subjects had to be enlightened collaborators and the role of introspection was more significant in an explanatory than in a purely observational context. Wundt's special requirements for the psychological experiment led him to reject other early models as exemplified by the hypnotic experiment in which the experimenter-subject relationship was closer to what was to become the norm in the twentieth century.
