Pupillary attributions of college students to happy and angry faces.

As evidence for an hypothesis that pupil size plays an important role in nonverbal communication, Hess (1975) has reported that adults draw in appropriately sized pupils on his happy and angry faces task. However, he did not report a statistical test of his data. In this study, we replicated Hess' research and found congruent with his hypothesis that college students (n = 223) draw in significantly larger pupils on the happy face.     

Analysis of the AAMD Adaptive Behavior Scale: public school version

Many state agencies have ruled that assignment of students to special education classes for the mentally retarded must be determined by assessment of verbal, performance, and adaptive behaviors. The AAMD Adaptive Behavior Scale: Public School Version was subjected to a normative and validation study using 291 subjects from the southcentral area of Texas. Data were collected from groups of regular and special education students, both white and nonwhite, at 8, 10, and 12 yr. of age. Results were compared to the original normative data provided in the AAMD manual and indicated that (1) the instrument is effective in discriminating between regular and special education groups; (2) a shortened version may be feasible and more practical; and (3) the derived total score may be useful and effective when used as a cut-off score for placement in special education for the mentally retarded.     

Attitudinal effects of the use of evaluatively biased language

In an experiment to study the effects on attitudes of requiring subjects to use evaluatively biased language, 84 schoolchildren aged 13–14 years completed a questionnaire to measure their attitudes on the issue of adult authority over teenagers, before and after writing an essay on this issue in which they were either required to incorporate words from a list all of which implied a positive evaluation of a pro-authority position or a negative evaluation of an anti-authority position (pro-bias condition), or required to incorporate words where the implied evaluations were reversed (anti-bias condition), or were given no words to incorporate (control condition). Relative to controls, pro-bias subjects showed as a shift towards a more pro position and anti-bias subjects became more anti irrespective of their initial attitudes (pro-bias versus anti-bias comparison, p<.01). However, when tested 6 days later most of this effect had disappeared, particularly in the case of subjects whose initial attitudes were least pro. At this final session, subjects also rated attitude statements on the issue in terms of scales constructed from the pro-bias and anti-bias word lists. In accordance with previous research, the more pro subjects' attitudes, the more they showed greater polarization of judgement on the pro-bias than the anti-bias scales (p<.000l). It is concluded that a person's attitude may be related to the kind of evaluative language he will apply to an issue, and that when a person is induced to use language implying a particular evaluation of an issue, he may change his attitude, at least in the short term, so as to be more congruent with the language he has used.     

An adolescent symptom checklist for juvenile deliquents

A rating instrument was developed to assess the personality functioning of problem adolescents who have a brief history of official delinquency. Subjects were 186 residents at a short-term diagnostic detention facility. The instrument that emerged from a factor analysis was tested for reliability, validity, and cross-situational generality. Two major orthogonal factors emerged, Apathy-Withdrawal (I) and Anger-Defiance (II). Each factor was found to be congruent with the corresponding dimension on behavior rating instruments that had previously yielded two orthogonal factors and that had been shown to be relevant to a large number of psychological and educational issues. Significant correlations between the factors and a series of global ratings measuring behavior and measures indicative of the frequency and seriousness of official delinquency provided further evidence of construct and discriminant validity as well as evidence of cross-setting consistency of personality functioning.     

The effect of syntactic encoding on sentence comprehension in aphasia.

This study compared two levels of syntactic encoding with respect to their effect on aphasics' auditory comprehension. The same informational content was presented either as an embedded sentence or as two contiguous simplé propositions. A similar contrast was utilized to compare sentences containing relational terms of time, comparison, instrumentality, as well as sentences involving conjunction reduction, with parallel messages expressed in expanded, simplified form. A picture-verification paradigm was used. Comprehension was significantly enhanced only in the case of embedded sentences, with a tendency for Broca's aphasics to show the maximum effects.     

Influence of six types of visual structure on complexity judgments in children and adults

Individuals at five grade levels (kindergarten, Grade 2, Grade 4, Grade 6, and college) made pair-comparison judgments of visual complexity. The influence of the presence or absence of six types of visual structure (double symmetry, vertical symmetry, horizontal symmetry, diagonal symmetry, checkerboard organization, and rotational organization) and of amount of contour were examined. Two general developmental trends were revealed: First, the age at which visual structure initially affected complexity judgments varied with the type of structure, independent of amount of contour, within the range of contour values used. Second, there was a uniform increase in the effect of structure on complexity judgments between the fourth and sixth grades. These results are discussed in relation to possible mechanisms of visual pattern encoding and complexity judgment.     

Interaction of stimulus size and retinal eccentricity in metacontrast masking

Metacontrast masking occurs both at the fovea and in the retinal periphery; foveally, the smallest stimulus elicited the strongest masking, whereas peripherally the reverse was the case. An analysis of variance showed a significant size effect, eccentricity effect, and size-eccentricity interaction. As stimulus size increased, the stimulus onset asynchrony of maximum masking shifted to greater values. Both foveal metacontrast and peak shifts contradicted predictions made by the hypothesis that metacontrast is mediated by an interaction of sustained and transient channels in the visual system. The data are consistent, however, with a lateral inhibitory model of metacontrast masking and stimulus coding.     

Visual-geometric illusions: unisex phenomena

The possibility of sex differences in responses to visual-geometric illusions was investigated with the use of forty-five illusion variants and a sample of 221 observers. No difference in illusion magnitude as a function of sex was found. A second experiment measured illusion decrement and transfer of decrement to other illusion configurations. Again there were no significant differences between male and female observers.
