Spatial localization in children after changes in position

Five experiments investigated the young child's ability to retrieve a target after a change in the position of the child or the target. In Experiments I–IV 2- to 4-year-old children were rotated 90, 180, 270, or 360° about a stationary square table containing four identical hiding locations at each of the cardinal locations. The children tested performed this task significantly better than chance, but their errors reflected either their response biases in the absence of any information as to the location of the target, or the repetition of a response which had been successful in retrieving the target prior to the change in position. When the children were forced to respond rapidly, these errors increased significantly. In Experiment V a table top was rotated 90, 180, 270, or 360° in front of 3- to 10-year-old children. There were two cue situations. The child saw the rotation, or the child had to infer the rotation. Young children made errors of the types observed in Experiments I–IV. The ability to inhibit these errors increased with age. By 7 years of age performance was virtually perfect when the child could observe the change in position of the hidden object. The ability to infer the positional change developed more slowly and was good but not perfect at 10 years of age.     

Utilization of groups in training for school consultation

The purpose of the present paper is to describe the utilization of groups over the past six years in our two semester school consultation practicum course. In addition, problems and issues raised by the utilization of groups are considered. Three tensions resulting from the utilization of groups are described and it is concluded that regardless of the complexity of the issues or the instructor's fallibility, the three tensions represent issues around which instructors must make decisions.     

Effects of fear of success, fear of failure, type of opponent, and feedback on female achievement performance

Female undergraduates (N = 240) assessed for fear of success (FS) and fear of failure (FF) competed against a male, female, or no opponent (norms) on an alpha-numeric substitution task. After completing one set of trials, subjects arbitrarily received success or failure feedback, then performed again. While there were no significant effects when subject's FS classification was based on total scores from the entire set of four cues used, performance effects were found for Horner's original cue: FS-absent females performed better against a male than a female opponent, whereas the reverse was true for the FS-present subjects. Two of the other FS cues interacted with FF: at low levels of FF, FS-absent subjects performed better than FS-present subjects; for high levels of FF, there were no differences between FS groups. A number of postperformance affect ratings were consistent with theoretical expectations that FS-present females would experience more negative effect over success in achievement contexts than would FS-absent females.     

The selective utilization of information in the optic array

Summary When ambulatory subjects wear prisms with bases vertically opposed before the two eyes, the direction of the after-effect measured on a localization task shows that there is a bias favouring selection of the field which contains more of the floor. Subjects allowed differential views of the floor with prism bases laterally opposed also show this bias. The bias is reversed if flow patterns from the lower visual field are eliminated. These studies support the view that information in the lower ambient field is selectively utilized during locomotion.This research was supported by Grant No. APA-1 from the National Research Council of Canada. Experiment 4 and a first replication of Experiment 1 were part of a thesis submitted by the junior author for the M.A. degree at the University of Toronto.     

Fertility Related Attitudes of Minority Mothers with Large and Small Families1

The relationship between certain attitudes and levels of fertility in five cultural groups–Blacks, Cubans, American Indians, migrant Chicanos, and white Protestants–was explored. Mothers, aged 35–45, with one or two children (small family, N= 253) or five children (large family, N= 196) were compared. Subjects responded to semantic differentials measuring attitudes toward pregnancy, family, abortion, sex, birth control, and parent. Large family mothers were generally more negative toward birth control, sex, and family. Cultures differed significantly on all six attitudes, with those toward abortion and pregnancy being the best discriminators. Significant interactions between cub ture and size were found on attitudes toward birth control and pregnancy. In general, large families wanted fewer children than they had and their negative attitudes toward birth control might be associated with their ineffective experiences; however, the trend was reversed in the migrant group where small family mothers were more negative toward birth control. Since small family mothers among migrant Chicanos were difficult to find and their estimates of ideal family size was large, it is likely that their negative attitudes toward birth mntrol reflected an aversion to its use.     

Is Justice Really Blind?–The Influence of Litigant Physical Attractiveness on Juridical Judgment1

The present investigation examined the influence of litigant physical attractiveness on the decisions of 91 undergraduates playing the role of nondeliberating jurors in an automobile negligence trial. Seeking to achieve a more realistic simulation of actual courtroom practice than that produced in prior studies, which have relied exclusively on short written synopses as their method of trial presentation, this experiment tested the hypothesis that physical attractiveness would have a significant impact on juridic judgments even though an audiovisual presentation of the trial permitted the introduction of a variety of other important stimuli typically present at a jury trial. This prediction received empirical support: Subjects exposed to an attractive plaintiff and an unattractive defendant more often found in favor of the plaintiff and awarded more money in damages than students viewing an unattractive plaintiff and an attractive defendant. However, in contrast to findings from general studies of interpersonal evaluation, analyses of student perceptions of the two litigants provided only limited evidence for a global (positive) physical attractiveness stereotype within the context of a simulated trial. Instead, the observed effect of physical attractiveness on student decisions was apparently mediated by differential perceptions of the seriousness of the accident itself. Possible implications of the results for the judicial process were mentioned.     

Modification of an impulsive cognitive tempo in emotionally disturbed boys

In order to determine the relative effectiveness of verbal self-instructions and training to delay before responding in modifying an impulsive cognitive style, 15 impulsive emotionally disturbed boys were assigned to one of three groups. The cognitive-training group was given practice in verbal self-instructions, the delay-training group received practice in delaying before responding, and the control group received no training. Posttreatment scores on the Matching Familiar Figures Test showed a significant increase in latencies for both the cognitive and delay-training groups. However, only the cognitive-training group, which had recieved practice in verbal self-instructions, made fewer errors following training. Implications for future research and potential treatment strategies for verbal self-instructions are discussed.

Specificity in contrast effects: Judgments of psychopathology

Three experiments were conducted to explore the specificity of the contrast effect in judgments of psychopathology. In the first two studies, respondents initially attempted to infer whether each item in a series of behavior samples (vocabulary definitions in one study, handwriting samples in the second) came from a schizophrenic or a nonschizophrenic patient. Some respondents were presented with highly pathological samples in this induction series, while others were presented with relatively nonpathological samples. These divergent experiences led to marked contrast effects in evaluating test stimuli from the same behavioral domain (e.g., additional vocabulary definitions), but had significantly less impact on the respondent's reactions to stimuli from a different domain (e.g., handwriting samples). A third experiment yielded similar results, using a paired-comparison methodology. In this study subjects first judged a series of high- vs low-pathology definitions. They were then presented with a series of matched stimulus pairs, each including one vocabulary definition and one hand-writing sample. Respondents were to indicate the member of each pair that seemed more indicative of schizophrenia. People assigned to the high-pathology induction group typically chose the handwriting samples as being more indicative of schizophrenia, compared with respondents who were assigned to the low-pathology conditions. These results were interpreted as supporting a representational (perceptual) theory of contrast.     

The use of photographs as occupational stimuli

The purpose of this study was to examine the potential of photographic stimuli portraying well-known occupational activities in order to elicit vocationally relevant responses. Color photographs of persons performing occupational tasks or activities were the stimuli used to determine if aspects of the photographs would elicit discriminating responses. Eighty special education high school students were asked individually to respond to 15 color photographs. Out of a maximum of 1200 possible picture identifications, 35 responses were scored incorrect or unknown as to content. These results indicated 97.1% effectiveness in identifying the stimulus content by this population. Therefore, photographs consisting of occupational content can discriminate as stimuli by eliciting content-appropriate responses. Implications for further research and application of this finding are discussed.
