Development of an Everyday Spatial Behavioral Questionnaire

The authors developed a 12-category, 116-item critical incident questionnaire of spatial behavior. The authors administered the Everyday Spatial Behavioral Questionnaire (ESBQ) to volunteer undergraduates (114 women, and 31 men) and tests of spatial ability to establish both the reliability and construct validity of the instrument. The authors found that Cronbach's alpha across the subscale scores was .92, and that 8 of the 12 subscales had alphas of .70 or greater. The authors found validity of the ESBQ through canonical correlation analysis. Specifically, spatial tests, gender, and age variables, jointly with the ESBQ subscales, identified 2 apparent continua of spatial skills. The authors labeled the first continuum movement through space (from moving a vehicle at one end of the continuum, to moving one's own body through space at the other end of the continuum). The authors labeled the second identified continuum drawing/perceiving perspective/path finding, and it appeared to represent a continuum of 3-dimensional visualization or redirection. Another suggested label was dimensional discernment. Thus, the ESBQ is a first step toward identifying new ways to think about and quantify people's spatial experience.     

Conflict monitoring and feature overlap: Two sources of sequential modulations

Recent findings demonstrating that the Simon effect diminishes when the preceding trial is a noncorresponding trial led researchers to develop two alternative accounts. The conflict monitoring account argues that the automatic activation from stimulus location information is under the regulation of a control mechanism, which adjusts the level of activation depending on conflict in the preceding trial. In contrast, the feature integration account holds that sequential modulations of the Simon effect can be attributed to the integration of stimulus and response features into event files. Previous research demonstrated a potential contribution to sequential modulations from both mechanisms. We use a four-choice task to extend these findings and to investigate the exact nature of the feature overlap effects. Both conflict monitoring and feature overlap effects were found to contribute to sequential modulations. However, the feature overlap effects did not conform to predictions of the feature integration account. We argue that the feature overlap effects are accounted for better by strategic shortcuts in response selection.     

Intuition, cognitive style, and hemispheric processing

200 undergraduate volunteers were administered Westcott's Test of Intuitive Ability, Witkin's Group Embedded Figures Test, Paivio's Revised Individual Differences Questionnaire, and visual and aural dominance measures using a three-field tachistoscope and dichotic listening device, respectively. Field dependence was consistently related to poorer intuitive performance. No sex-related differences were found on intuition, embedded figures, Paivio's questionnaire, or dominance scores although the amount of intuition explained by cognitive style and dominance differed by hand and gender. Visual-verbal style was not associated with dominance while the relation of field dependence-independence and dominance was inconsistent. Neither dominance nor visual-verbal style was consistently related to intuition although complicated associations were indicated by hand and sex, suggesting differences in cognitive organization.     

Stability over age and sex of children's responses to embedded figures test

240 children in Grades K to 4 were administered the entire Children's Embedded Figures Test to determine whether similar factor structures are obtained from samples of different sex and age as well as when the population is randomly split. Data were analyzed by principal axis factor analysis and relevant factor structures were compared using Veldman's 1967 program "Relate". There was one stable factor which was consistent across sex and accounted for about 19% of the variance. Results were inconsistent across grades and indicated a possible lack of agreement of factor structures.     

Stimulus intrusion on fixed-interval responding in the rat: The effects of electric shock intensity,temporal location,and response contingency

After a scalloped lever-press response pattern had developed under a fixed-interval food reinforcement schedule, a 15-sec electric shock was intruded for different groups of rats in the first, second, third, or fourth quarter of each inter-reinforcement interval. Shock intensity was systematically increased for individual rats over 70 sessions, from 0.05 to 1.6 mA. Additional between-groups comparisons involved response-dependent versus clock-dependent fixed-interval schedules, and response-dependent versus response-independent electric shock intrusion. Response rates within each fixed interval prior to, during, and following electric shock intrusion showed regular and reproducible increases and decreases under systematic application of the experimental variables. These results provide further evidence that the functions of a stimulus are determined in part by the parameters of intensity, response contingency, and temporal location with respect to reinforcement.     

Generalization and discrimination of shape orientation in the pigeon

Pigeons learned to peck a green key on which parallelogram-shapes were projected; they then received generalization tests in which the orientation of the parallelogram was varied. Nondifferential training produced very little eventual stimulus control along the orientation dimension, but when training included S- trials (absence of the parallelogram) subjects responded consistently more to certain orientations than to others. Unlike typical results for visual generalization (e.g., line-tilt), the tilt gradients obtained for this complex stimulus were bimodal, supporting predictions on the basis of human perceptual data. However, unimodal gradients could be produced by specific discrimination training along the orientation dimension. Other forms of intradimensional training also produced relatively steep gradients, often characterized by unexpected but consistent secondary peaks. An attempt to obtain inhibitory gradients (S+: green key; S-: parallelogram on a green background) resulted in virtually zero responding all along the shape-orientation dimension; therefore, specific inhibitory control could not be evaluated. All these experiments suggest that definition of this complex stimulus dimension in terms of mere "angular orientation" is inappropriate, and alternative interpretations are discussed.     

Desiring and expecting to work among high school girls: Some determinants and consequences

The effects of mother's and father's work status and of social-psychological intervening variables on high school girls' orientation to the labor force are examined. The dependent variables are separate indicators of whether the girls want and whether they expect to have an occupation. In these data from 1965, a log linear analysis shows that whether the mother worked was the major background influence on the dependent variables; father's occupation had no significant independent effect. In addition, two “ideological” variables, the girl's identification with the mother and beliefs in individual achievement, strongly influenced the dependent variables, in a way that did not merely mediate the background effects. Finally, some consequences of wanting and/or expecting to work are examined, and it is argued that the choice of career pattern (housewife versus paid employment) was a central one in girls' attitudinal structures.
