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.

Studies of the Poggendorff illusion (a transversal interrupted by parallel lines) showed that illusory effects increased linearly with increasing separation between the parallels, increased in inverse proportion to the tangent of the angle of intersection between transversal and parallels, decreased whenever line segments (other than a transversal segment) were omitted, decreasing to zero when the segment of a parallel forming the obtuse angle with the transversal was omitted, and varied systematically with the tilt of the whole display, approaching zero when the transversal was oriented in a horizontal or vertical position. Hypothesis: The Poggendorff illusion involves at least three kinds of effects on the perceived orientation of a segment: distortion by other segments (especially a segment intersecting at an obtuse angle), stability of vertical and Horizontal orientations, and assimilation towards vertical or horizontal. 相似文献

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. 相似文献

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. 相似文献

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. Grant Foundation. The authors would like to thank Lina Jandorf for her invaluable assistance in data collection and scoring. 相似文献

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. 相似文献

In Experiment 1, performance on a conventional (full) rod and frame was compared with that on three other displays. These included a closure condition in which only the corners of a luminous frame were present, a subjective contour condition in which the rod was seen against ablack square subjective surface, and a pattern condition in which four luminous disks were arranged to form the corners of a square pattern. In all cases, a square-like form was perceived. The rod-and-frame effect (RFE) was greatest on the full frame, which differed significantly from all the rest. Closure produced the next greatest influence, while the responses to subjective and pattern conditions did not differ from each other. Experiment 2 showed that a subjective frame was no more effective than the subjective surface of Experiment 1, and verified the importance of 90-deg corner elements in the rod-and-frame display. The conclusion drawn was that equivalent form organizations are not sufficient to produce equivalent levels of the RFE, but certain luminance-difference contours appear to be essential. 相似文献
