A developmental study of children's preferences for paintings

In order to study the influence of style and subject matter on the development of children's art preferences, 60 randomly selected subjects from three grade levels, with an equal number of males and females, were shown ten color slides of paintings representing five categories of subject matter and two broad categories of style. Results indicated that style was the dominant variable at each grade level, and consistently accounted for more of the overall variance than subject matter. Unexpectedly, no appreciable developmental differences were evident in preference judgments across grade levels observed in this study.     

Early selective-attention effect on evoked potential reinterpreted

In a dichotic listening situation stimuli were presented one at a time and at random to either ear of the subject at constant inter-stimulus intervals of 800 msec. The subject's task was to detect and count occasional slightly different stimuli in one ear. In Experiment 1, these ‘signal’ stimuli were slightly louder, and in Experiment 2 they had a slightly higher pitch, than the much more frequent, ‘standard’, stimuli. In both experiments signals occured randomly at either ear. Separate evoked potentials from three different locations were recorded for each of the four kinds of stimuli (attended signals, unattended signals, attended standards, unattended standards). Contrary to Hillyard et al. (1973), no early (N₁ component) evoked-potential enhancement was observed to stimuli to the attended ear as compared with those to the unattended ear, but there was a later negative shift superimposed on potentials elicited by the former stimuli. This negative shift was considered identical to the N₁ enhancement of Hillyard and his colleagues which in the present study was forced, by the longer inter-stimulus interval used, to demonstrate temporal dissociation with the N₁ component. The ‘Hillyard effect’ was, consequently, explained as being caused by a superimposition of a CNV kind of negative shift on the evoked potential to the attended stimuli rather than by a growth of the ‘real’ N₁ component of the evoked potential.     

Effects of implementing (APA) ethical principles in collecting classroom data

The study examined the effects of providing six levels of research information to 270 classroom subjects on the data obtained from three different cognitive tasks. The effects of the three tasks on the subjects' academic self-concepts were also investigated. No significant differences were found among the six levels of information for each of the three tasks. On the logical task a significant linear relationship was found supporting previous research which indicates that the more information that is given to research subjects, the more negative the results. There were no significant differences on self-concept scores across the three tasks used. Overall, the implementation of ethical principles had little effect on data collected in classroom settings, indicating support for implementation. This data did indicate, however, that providing more information than required under the ethical principles can result in data bias on a specific task.     

The stability of status orientations among young,white, rural women from three southern states

This paper reports the results of a panel study of young, white, rural women from Georgia, South Carolina, and Texas (N = 138). The study was primarily concerned with how social origin variables affected early educational and occupational orientations and how early states of these orientations affected the orientations themselves at a later point in time. The results indicated that mother's education had a greater effect than father's education, but in either case the effect is mediated by intervening influences such as early aspirations and expectations. These young women held very traditional status orientations (with 60% projecting the occupations of beautician, nurse, stenographer, or school teacher), and their orientations were quite stable between their sophomore and senior years in high school. Since there has been so little work reported on the status attainment process for women, and rural women in particular, this study does offer a limited insight into this phenomenon.     

The children of Mexican-American migrant workers: A population at risk?

The present study assessed intellectual, academic, and emotional strengths and weaknesses for a group of Mexican-American children of migrant farm workers. In order to test the vulnerability hypothesis, the test profiles of these children were contrasted with those of two groups of black children with similar demographic makeup. The children of one group (Clinical Black) had been referred previously for a psychological consultation while the children of the other (Nonreferred Black) had not. Across dependent measures, between-groups contrasts tended to describe the scores of the Migrant children as similar to those of the Clinical Black children and significantly below those of the Nonreferred Black children. The findings suggested specific intellectual, academic, and emotional vulnerabilities of the Migrant children and demonstrated the need to develop ameliorative programs for these children.The authors wish to thank the staff of C & Y, University of Virginia Hospital, especially Ms. Deborah Johnson and Ms. Suzanne Canale, whose cooperation and assistance made this project possible.     

REM motivation induced by brief REM deprivation: the influence of cognition, gender, and personality.

Prominence of the brain's right-hemisphere information processing and intensity of dream experience are two theoretically related constructs that have been proposed as important psychological aspects of REM sleep. Either view is consistent with the prediction that the effect of REM deprivation will depend in part on the nature of cognitive activity that is initiated at the onset of each REM period and that "substitutes" for the interrupted REM process. In the present study, the effect of REM deprivation was more striking for female subjects given a digits task than for female subjects given a fantasy-reporting task during awakening used to induce REM deprivation for the first 6 hours of the night. High neuroticism appeared to exaggerate the effect. No corresponding pattern was observed for the male subjects. These preliminary finding may be exaggerated by cognitive activity that is functionally incongruent with those processes. The results also raise interesting questions about individual differences.     

Completely nonmetric multidimensional scaling

Most of the distance models underlying multidimensional scaling assume that if a stimulus y is between the stimuli x and z on each dimension, then x and z should be the farthest apart of the three stimuli. An iterative algorithm is described that uses only this betweenness prediction to infer the ordering of a set of stimuli on each of one or two dimensions. Applied to previously published semantic similarity data, this algorithm produced two-dimensional configurations that were similar in appearance to Euclidean configurations but generally involved fewer violations of the betweenness prediction.     

A measure of autonomy

This article reports the development of a measure of indicidual differences in autonomous rule compliance. The autonomy scale (a short, easily administered CPI based test) was developed within the framework of a multidimensional, role-theoretical model of moral development. Five samples were used in the construction of the scale. Two of the samples (total n = 111) were used to derive the autonomy scale. The items for the scale were derived through the sequential use of two common item selection stategies: criterion keying and factor analysis. An initial set of 55 CPI items were derived using an "ideal" autonomy Q-sort profile as a selection criterion, and an Alpha factor solution was used to reduce this initial pool to a final set of 25 items. Several analyses were conducted using three additional samples (total n = 245) to estimate the reliability of the scale and determine its validity. The results of these analyses provide initial evidence for the content, criterion-realted, and construct validity of the scale and indicate that the measure has an adequate reliability.     

An ecological study of the reliability of clinical judgment in executive appraisal

This research was a study of the reliability of clinical judgment findings (multitrait) across three different information sources (psychometric tests, structured interview, and psychometric tests and interview). Subjects (N = 74) were middle and senior executives of Western Canadian technical companies; clinicians (N = 3) were trained and experienced industrial psychologists. The study investigated the similarity of clinical evaluation of personological characteristics (based on an 18-factor multitrait paradigm) across the three different information sources. Subjects were independently rated by a single clinician on 18 criterion factors in each of the three information source categories. Test information source categories required the administration of approximately 12 hrs of standardized psychological assessment questionnaires to each of the 74 subjects. Interview source category involved a 1.5-hr structured interview per subject. Combined condition pooled both test and interview conditions. Generalizability of the findings was maximized by the undertaking of the experiment in a natural situation thus increasing ecological validity. Statistical treatments used were designed to assess the similarity of a clinician's evaluation of a subject based on the different category of information available about that client. Convergence (intrarater reliability) indexes range from a high of .64 to a low of .05. Results indicate a varying degree of convergence of multitrait clinical ratings dependent on clinician and trait being rated. Results are discussed in terms of implications for practitioners involved in executive personnel selection.
