EXPOSURE TO INDUSTRIAL AND URBAN ENVIRONMENTS AND FORMAL SCHOOLING AS FACTORS IN PSYCHOLOGICAL DIFFERENTIATION

The influence on psychological differentiation exerted by exposure to industrial and urban environments and to formal schooling was investigated with the help of Story-Pictorial EFT administered on 240 7–10-year-old children belonging to the Santhal tribe residing in and around an industrial city in Bihar. A 2 × 2 × 2 ANOVA performed on differentiation scores revealed significant main effects of industrial and urban exposures, and of schooling. Significant 3-way interaction effect indicated that the impact of urbanization in the industrial and non-industrial settings varied with exposure to formal schooling, and that the main effects in spite of their being statistically significant have to be taken with caution. Impact of the three factors on psychological differentiation is interpreted in terms of changes induced through acculturation that alter the experiential base of the individual as well as cultural characteristics of this environment.

Group Affiliations of University Students in the Arab Middle East

Summary

A study was undertaken in Morocco in order to separate the effects of age and formal schooling on the development of cognitive style. A total of 384 boys (age range: 6–22 years) were selected from environmental backgrounds including: urban/schooled, rural/schooled, urban/nonschooled, and rural/nonschooled. Results indicated that chronological age and schooling played major, but independent roles in promoting perceptual development (and “field independent” cognitive style), while childhood environment appeared to have little effect. It was concluded that general statements about the effects of cultural socialization practices on cognitive style should be tempered by considering particular environmental experiences (such as formal schooling) that may significantly influence cognitive assessment techniques that are said to measure cognitive style.

THREE TYPES OF FAMILY STRUCTURE AND PSYCHOLOGICAL DIFFERENTIATION: A STUDY AMONG THE JAUNSAR-BAWAR SOCIETY*

The study examines the influence of family structure and family experiences on psychological differentiation in children. Three types of families, viz., monogamous, polyandrous and polygynandrous were selected from the polyandrous society of Jaunsar-Bawar in the Cis-Himalayan region of India. 175 boys and girls of age groups 7-9 and 13-15 years, belonging to the three types of families, were administered the Story-Pictorial EFT, Indo-African EFT and BD tests. Family experiences of the child were assessed through ratings and interview. A 2×3×2 ANOVA performed on differentiation scores revealed significant age and sex effects. Family effect was not statistically significant. But the data suggested a strong trend in the expected direction. The findings have been discussed in terms of the characteristic family patterns of Jaunsar-Bawar and acculturation factors.

The field dependence/independence cognitive style does not control the spatial perception of elevation

Earlier work described the presence of a significant connection between an individual's ability to disregard distracting aspects of a visual field in the classical rod-and-frame test (RFT), in which a subject is required to set a rod so that it will appear vertical in the presence of a square frame that is roll tilted from vertical, and in paper-and-pencil tests, in which the subject is required to find a hidden figure embedded in a more complex figure (the Embedded Figures Test [EFT]; see, e.g., Witkin, Dyk, Faterson, Goodenough, & Karp, 1962; Witkin et al., 1954; Witkin, Oltman, Raskin, & Karp, 1971). This has led to a belief in the existence of a bipolar dimension of cognitive style that is utilized in such disembedding tasks--namely, the extent to which an individual is dependent on or independent from the influence of a distracting visual field. The influence of an inducing visual field on the perception of elevation measured by the setting of a visual target to appear at eye level (the visually perceived eye level [VPEL] discrimination) has also been found to be correlated with the RFT. We have thus explored the possible involvement of the dependence/independence cognitive style on the VPEL discrimination. Measurements were made on each of 18 subjects (9 of them female, 9 male) setting a small target to the VPEL in the presence of a pitched visual field across a range of six pitches from -30 degrees (topbackward) to +20 degrees (topforward) and on each of three tests generally recognized as tests of cognitive spatial abilities: the EFT, the Gestalt Completion Test, and the Snowy Pictures Test (SPT). Although there were significant pairwise correlations relating performance on the three cognitive tests (+.73, +.48, and +.71), the correlation of each of these three with the slope of the VPEL-versus-pitch function was not significant, as it was with the slope of the perception of visual pitch of the field (PVP)-versus-pitch function. VPEL, PVP, and a cognitive factor separated into three essentially independent factors in a multiple-factor analysis, with the three cognitive tests clustering at the cognitive factor, and with no significant loading on either of the other two factors. From the above considerations and a multiple-factor analytic treatment including additional results from this and other laboratories, we conclude that the cognitive-processing style held to be involved in the performance on the EFT and the perception of vertical as measured by the RFT is not general for egocentric space perception; it does not involve the perception of elevation.     

Work, family and life-course fit: Does control over work time matter?

This study moves from “work-family” to a multi-dimensional “life-course fit” construct (employees’ cognitive assessments of resources, resource deficits, and resource demands), using a combined work-family, demands-control and ecology of the life course framing. It examined (1) impacts of job and home ecological systems on fit dimensions, and (2) whether control over work time predicted and mediated life-course fit outcomes. Using cluster analysis of survey data on a sample of 917 white-collar employees from Best Buy headquarters, we identified four job ecologies (corresponding to the job demands-job control model) and five home ecologies (theorizing an analogous home demands-home control model). Job and home ecologies predicted fit dimensions in an additive, not interactive, fashion. Employees’ work-time control predicted every life-course fit dimension and partially mediated effects of job ecologies, organizational tenure, and job category.     

Validation,Persuasion and Recycling: Capitalizing on the Social Ecology of Newspaper Use

Two experiments used clinical validation to increase scrutiny of messages posted in public settings. The first experiment used a 2 (validation: no/yes) × 2 (persuasion: none/"it is important") factorial design to develop messages about newspaper recycling. The prompt (no validation/no persuasion) had little impact on newspaper recycling, but the other 3 signs all resulted in increased recycling while the signs were in place. After signs were removed, recycling remained significantly higher than baseline (marginally significant for validation/persuasion). At the end of the study, number of cognitions favoring recycling was significantly higher in the validation-only condition and was lower in the validation/persuasion condition. Experiment 2 tested whether signs would have more impact if they were sensitive to the social ecology of newspaper recycling; that is, readers' tendency to leave newspapers behind so others may read them. Messages based on a 2 (message: validation-only/validation plus persuasion) × 2 (ecology: no social ecology/social ecology) factorial design supported social ecology's importance. Furthermore, because of the increased sharing in the social ecology conditions, total numbers of newspapers used was significantly lower in those buildings. Validation only yielded sustained behavior change in both Experiments 1 and 2, supporting additional research on the question of whether validation can, by itself, lead to cognitive elaboration and self-persuasion.     

Construct validity of perceptual style: Role of stimulus size in the embedded-figures test and the rod-and-frame test

Three experiments were performed in order to test the construct validity of perceptual field dependence (FD) and field independence (FI). In Experiment 1, performance of subjects on two sizes of Form A of Witkin’s Embedded Figures Test (EFT) with a size-ratio of 1 to 4 was compared. The size of the standard EFT was taken as unity. A nonsignificant size effect was found for all subjects as a group, and a significant rank correlation was found between performances on the two sizes of the EFT. Furthermore, the performance of field-dependent subjects (as defined by performance on the standard EFT) and field-independent subjects did not interact significantly with the size factor. In Experiment 2, the physical size of the EFT changed from 1 to 8. A nonsignificant, overall size effect was again found, but the EFT performance of fielddependent and field-independent subjects interacted significantly with the size factor. In Experiment 3, the performance of subjects on two sizes of the EFT (i.e., 1 to 8) and two sizes of the standard rod-and-frame test (RFT) (i.e., 1 to 4.5) were compared. A significant stimulus-size effect was found in the EFT, with all subjects becoming morefield-independent, and a significant stimulus-size effect was found in the RFT with the same subjects becoming morefield-dependent. Finally, the EFT performance of the field-dependent and field-independent subjects again displayed a significant interaction with the size of the embedded figures. A parallel-serial processingstyles hypothesis is proposed to account for the EFT data.

Motion perception and aging.

The authors used a correlated motion paradigm to investigate the effects of aging and gender on motion sensitivity. In 2 experiments with a total of 50 elderly and 50 young subjects, motion thresholds were significantly higher for elderly women. The correlated motion signal, which was embedded in random motion, may have been coherent to subjects in much the same way a form is in Witkin's Embedded Figures Test (EFT). In Experiment 2, EFT scores were obtained. A significant positive relationship between motion thresholds and EFT performance was found within each age group. Although gender-related perceptual style differences may contribute to motion perception effects, the authors argue that a common neural factor contributes to performance on both the EFT and the correlated motion task.     

THE CONSISTENCY OF NIGERIANS' PERFORMANCE ON THREE TASKS MEASURING FIELD DEPENDENCE

The study attempts to examine the consistency of Nigerians' performance on three measures of field dependence. The measures used were the Embedded Figures Test (EFT), Block Design (BD) and the Rod and Frame Box (RFB), and samples were drawn from a university (N = 48) and two local schools (N = 38) located in east-central Nigeria. In line with previous studies, the most significant correlation was between EFT and BD. Interpretation of the partial correlations suggested that EFT and BD may share at least two common factors but that each appears to share only one of these with RFB. These factors were discussed in terms of the hemispheric processing requirements of these measures. It was suggested that EFT and BD, which involve cognitive restructuring, may require an ability to integrate the processing abilities of the two hemispheres, whereas RFB may only involve left hemisphere processing. This interpretation may also help to explain some of the sex and age effects found in the present study. More research is needed to help isolate the various processing requirements of the different measures of field dependence.     

A cross-national study of cognitive style among managers and technicians(1)

This study explains differences among managers and technicians in twenty-two non-western countries in terms of the field articulation cognitive style. A review of the behavioral referents of the field articulate cognitive style suggested that this variable is appropriately related to occupational interests and tasks and adaptability to industrial technique. Previous studies also suggested the hypothesis that socioeconomic status variables are related to both cognitive style and national or cultural differences. This hypothesis was confirmed using both the EFT and the RFT as measures of field articulation in a group of three hundred twenty-nine managers and technicians representing twenty-two non-western developing countries. Several explanations of these findings are discussed in terms of functional requirements for adult roles in a society and in terms of the relative affluence or level of poverty.     

Do process simulations during episodic future thinking enhance the reduction of delay discounting for middle income participants and those living in poverty?

Two studies examined whether episodic future thinking (EFT; pre‐experiencing future events) reduces discounting of future rewards (DD). No studies have investigated whether process simulations (i.e., simulating the process of executing a future event) amplify EFT's reduction of DD. Study 1 examined the effect of incorporating process simulations into EFT (N = 42, M_age = 43.27; 91% female, family income = $75,976) using a 2 × 2 factorial design with type of episodic thinking (process, nonprocess/general) and temporal perspective (EFT, episodic recent thinking) as between‐subjects factors. Study 2 replicated Study 1 in a sample of adults living in poverty (N = 36; M_age = 38.44, 88% female; family income = $25,625). The results of both studies showed EFT reduced DD, but process‐oriented EFT did not amplify the effect of EFT. Our findings suggest the key ingredient in EFT's effect on DD is self‐projection into the future. This was also the first study to show EFT improves DD in a sample living in poverty.

The development of episodic future thinking in middle childhood

The ability to imagine future events (episodic future thinking—EFT) emerges in preschoolers and further improves during middle childhood and adolescence. In the present study, we focused on the possible cognitive factors that affect EFT and its development. We assessed the ability to mentally project forward in time of a large cohort of 135 6- to 11-year-old children through a task with minimal narrative demands (the Picture Book Trip task adapted from Atance and Meltzoff in Cogn Dev 20(3):341–361. doi:10.1016/j.cogdev.2005.05.001, 2005) in order to avoid potential linguistic effects on children’s performance. The results showed that this task can be used to assess the development of EFT at least until the age of 8. Furthermore, EFT scores correlated with measures of phonological short-term and verbal working memory. These results support the possibility that cognitive factors such as working memory play a key role in EFT.     

Piagetian Studies of Cognitive Development in India

The paper presents a review of studies on cognitive development of children in India inspired by Piaget’s theory of cognitive development. Piaget’s theory is briefly introduced before examining its cross-cultural applications. Early studies of cognitive development, which focus on age-related changes in cognition, are described. These are followed by the studies of the last decades in which developmental contexts, such as those provided by ecology, culture, schooling, and various forms of training, are implicated. Studies of spatial cognition are discussed in some detail and points of convergence between findings of Indian studies and those reported by Piaget are critically examined. The issue of “performance” vs. “competence” is addressed and research evidence that considers performance difference as a matter of cognitive style is presented. Possible reasons for decline of research interest in Piagetian studies in recent years is examined and suggestion for future studies in this field are offered.     

Sex of leader,leader behavior,and subordinate satisfaction

A 2×2×2 factorial design was employed to examine the influence of instructed leadership style, sex of leader, and sex of followers on leader behavior, subordinate satisfaction, and productivity in a simple task. In general, male and female leaders were equally able and equally willing to display autocratic and democratic leadership styles if so instructed. Similarly, leader sex did not have a significant influence on subordinate satisfaction or productivity either by itself or in interaction with leadership style or follower sex.
