Transcendental meditation and mirror-tracing skill.

Learning, performance and patterns of inter- and intra-individual variability of 32 experienced Transcendental Meditators were compared to those of 32 non-meditators. The data indicated that certain effects attributed to the practice of Transcendental Meditation (such as increased alertness and maintenance of attention, greater consistency and less anxiety) are not manifested in terms of learning and performance of a novel perceptual-motor skill.

Field dependence and the effect of REM deprivation on thirst.

Recently a number of studies have concerned the possible function of rapid eye movement (REM) sleep and the mastery of stress. The present study was designed to explore the possibility that REM sleep might play a function in reducing the potency of a stressful physiological stimulus, thirst, as well as the possibility that such a function might be specific to individuals falling at different points along the field-dependence dimension. While there was no difference between REM deprivation and non-REM awakening nights in subsequent morning thirst, there was a significant interaction between field dependence and night on morning thirst measures for 10 college students. These results are discussed in light of previous work on stylistic differences in dreaming and their possible role in adaptation to stress.

Influence of cognitive style on an incidental memory task.

The present study investigated the interaction between cognitive style, imagery, and memory. The Tactual Performance Test Location Score from the Halstead-Reitan battery was used as a measure of incidental tactual memory and mental imagery. The Group Embedded Figures Test was used to assess cognitive style. Results for 38 Caucasian males of mean age 49.9 yr. suggest that cognitive style is related to an individual's ability to perform a non-verbal, non-visual memory task. Further, cognitive style may be an important mediating variable influencing intrapersonal behaviors such as non-verbal memory and mental imagery.

Extent of psychological differentiation and creativity.

Among the extensive array of studies relating Witkin's construct of psychological differentiation to many psychological functions and variables, none seem to have adequately tested its relationship to creativity, although these two variables have personality traits and development characteristics in common and require similar skills for effective performance. Eighty-five male high school students were separated according to Embedded Figures Test, and the extreme groups tested for creativity by eight factorially pure tests developed by Guilford, and by Schaefer and Anastasi's Biographical Inventory. Statistical procedures included analysis of covariance, analysis of variance, and a matrix of intercorrelations. With intelligence controlled, field-independent persons performed significantly better than field-dependent persons on measures of visualization, spontaneous flexibility, adaptive flexibility, and creativity in mathematics and science but not significantly better on the other six creativity tests.

Critical analysis of a study on field dependence in young children.

Kojima's conclusion that our method of scoring performance in the rod-and-frame test did not produce satisfactory results in young children was invalid because our scoring method was used incorrectly, fallacious reasoning was used to reject our scoring method, subjects were classified wrongly, and the procedure used to test vertical perception in the children probably was unreliable.

Restructuring ability and patterns of physics achievement.

For a sample of 24 male and 19 female college students, persons with high visualization (F1,36 = 7.60, P less than .01) and low flexibility of closure (F1,36 = 6.54, P less than .02) attained significantly higher achievement in physics than persons with low visualization or high flexibility of closure. Persons with high restructuring ability and high spatial visualization (M = 88.64, SD = 15.6) attained a significantly higher level of physics achievement than persons with high restructuring ability and low spatial visualization (M = 56.5, SD = 25.1). Flexibility of closure, spatial visualization, and the embedded figures test accounted for 23.8%, 18.4%, and 53% of the variability in physics achievement among the entire sample, among amles, and among females, respectively. The data provided moderate support for the field-dependence--independence model of psychological differentiation and for investigators who reported a possible link between field-dependence--independence, visualization, and extent of neurological lateralization.

Field-dependence/field-independence and labeling of facial affect.

56 high school students were administered the Group Embedded Figures Test and the Pictures of Facial Affect. A low Pearson product-moment correlation of .02 was obtained between the measures. Data indicated that field-dependent and field-independent individuals were not signficantly different in their skills of labeling pictures of facial affect.

Effects of some social variables on field dependence.

The effects of socio-economic status, father's absence, family size, and birth order on the field dependence of Grade 6 elementary school children in Jamaica, West Indies, were examined. To 206 boys and 212 girls from 5 urban schools the Hidden Figures Test and a questionnaire were administered. For girls, but not for boys, field independence correlated significantly and positively with socio-economic status, but significantly and negatively with father's absence. No significant relation existed for the boys. Field dependence had no significant relation with family size and birth order.

Reliability and validity of the Group Embedded Figures Test for a grade school sample.

Data on validity of the Group Embedded Figures Test for 22 sixth grade students (9 boys and 13 girls) were obtained. 50 wk. later all subjects were individually screened on the Portable Rod-and-Frame Test and after a period of 2 more weeks, when they were retested on the embedded figures, data on reliability were obtained. Long-term coefficients of stability of .80 and .71 for the 9 boys and 13 girls, respectively, were obtained. Coefficients of internal consistency ranged from .83 to .98 for boys and girls. Coefficients reflecting both construct and concurrent validity were -.60 and .00 for boys and girls, respectively. Customary sex differences with respect to field-dependence--independence were not observed for these small samples.

Effect of practice and training in spatial skills on embedded figures scores of males and females.

The effect of practice and training in spatial skills on scores obtained by male and female students on the Embedded Figures Test was examined. Forms A and B were administered 6 wk. apart to three groups of subjects (ns = 28, 27, 27) enrolled in drafting, mathematics, and liberal arts courses. During the pretest-posttest period the drafting students received training while the other two groups served as controls. Analysis indicated (1) no initial sex difference in test scores; (2) liberal arts students differed significantly from drafting and mathematics students, but there was no significant difference between the last two groups; (3) all groups improved with practice; (4) women receiving training improved more than women who did not; (5) there was a trend toward women receiving spatial training scoring more poorly than males receiving training on the pretest, but there was no significant difference on the posttest. These results suggest that sex differences in embedded-figures scores found by many previous experimenters may have been associated with differences in prior experience in spatial skills and by a confounding of sex with area of academic study.

Cognitive predictors of articulation in writing.

Among 106 college students scores on a spontaneous 20-min. essay were regressed on referents of verbal and visual spatial ability. 26% of the variability in writing articulation among males was accounted for by the regression of graded writing scores against logical relations and embedded figures tests. 82% of the variability in writing ability among (females was accounted for by the regression of graded writing scores on visual closure, reading comprehension, spatial visualization, and embedded figures tests. The use of verbal and visual sptial referents as predictors of the degree of articulation in spontaneous writing samples consistent with sex-specific models of.cerebral lateralization was described.

Sex differences in feedback: effects on Rod-and-Frame performance.

It has been demonstrated that feedback is effective in changing rod-and-frame performance for women if given the opportunity to adjust the rod to the vertical repeatedly from the same starting position. It is also shown that the significant difference between males and females in the Rod-and-frame Test is carried by the large difference in the initial tilting position.

Effects of type of information (abstract-concrete) and field dependence on asymmetry of hand movements during speech.

Asymmetry of object-focused (gestural) and body-focused (self-touching) movements was investigated in a sample of 14 field dependent and 14 field-independent right-handed male college students. The data were obtained from standardized, videotaped interviews which consisted of an abstract and a concrete communicative task. Significant right-hand asymmetry was found for gestures which depict or represent (motor primary movements,p less than .01) but not for nonrepresentational speech primacy movements. In general, field-independents had greater right-hand asymmetry than field-dependents for object-focused movements, whereas field-dependents showed more left-hand asymmetry of self-touching. Results are discussed in terms of a possible relationship between extent of movements asymmetry and the use of visual imagery in verbal encoding.

Field independence, lateralization and defensive style.

This study investigated the relationship between field independence and defense clustering as measured by the Defense Mechanisms Inventory and lateral eye movements. Subjects had previously been classified either as hysterical or obsessive style by the Rorschach and WAIS Comprehension subtest. Previous findings indicate that these subjects have a preferred direction of lateral eye movement in a questioning format (hysterical style = left; obsessive style = right). This study found no relationship between field independence and defense clustering and lateral eye movements. To the extent that eye gaze indexes hemispheric activation, we conclude that neither field independence nor defense clustering was related to hemispheric lateralization.

Field dependence and short-term memory.

This study examined the relationship between field dependence and short-term memory. It was predicted that relatively field-independent individuals would perform better on short-term memory tests in which a large amount of interference is assumed to be present than would individuals who are more field-dependent. Subjects' appraisals of their own attentional facility, as well as their thoughts and feelings about the experimental tasks, were also elicited, and were looked at in terms of their relationship to field dependence and short-term memory.
