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.     

Assessing the stability of principal components using regression

This paper presents an analysis, based on simulation, of the stability of principal components. Stability is measured by the expectation of the absolute inner product of the sample principal component with the corresponding population component. A multiple regression model to predict stability is devised, calibrated, and tested using simulated Normal data. Results show that the model can provide useful predictions of individual principal component stability when working with correlation matrices. Further, the predictive validity of the model is tested against data simulated from three non-Normal distributions. The model predicted very well even when the data departed from normality, thus giving robustness to the proposed measure. Used in conjunction with other existing rules this measure will help the user in determining interpretability of principal components.The authors would like to thank the four anonymous reviewers and the two editors for their valuable comments.

Infant search tasks reveal early concepts of containment and canonical usage of objects

It is difficult to gain unambiguous evidence on the use of concepts by infants. Many results can be accounted for in terms of action-based strategies. The evidence reported here fulfils the minimal criteria for the operation of working concepts in infants. Search tasks are used with a filled interval which forces memory-search, and the object is hidden in containers which fulfil their customary job or violate it. Infants treat an upright cup as a more reliable location marker than an inverted one. A series of experiments probes the phenomenon. The results indicate that the infants have a working concept of containment which can be triggered by the provision of containers in their canonical orientation. Even “object permanence tasks” lead infants to access their knowledge of the relationships into which things typically enter in the world outside the laboratory.

Contribution of color to face recognition

One of the key challenges in face perception lies in determining how different facial attributes contribute to judgments of identity. In this study, we focus on the role of color cues. Although color appears to be a salient attribute of faces, past research has suggested that it confers little recognition advantage for identifying people. Here we report experimental results suggesting that color cues do play a role in face recognition and their contribution becomes evident when shape cues are degraded. Under such conditions, recognition performance with color images is significantly better than that with gray-scale images. Our experimental results also indicate that the contribution of color may lie not so much in providing diagnostic cues to identity as in aiding low-level image-analysis processes such as segmentation.     

The role of eyebrows in face recognition

A fundamental challenge in face recognition lies in determining which facial characteristics are important in the identification of faces. Several studies have indicated the significance of certain facial features in this regard, particularly internal ones such as the eyes and mouth. Surprisingly, however, one rather prominent facial feature has received little attention in this domain: the eyebrows. Past work has examined the role of eyebrows in emotional expression and nonverbal communication, as well as in facial aesthetics and sexual dimorphism. However, it has not been made clear whether the eyebrows play an important role in the identification of faces. Here, we report experimental results which suggest that for face recognition the eyebrows may be at least as influential as the eyes. Specifically, we find that the absence of eyebrows in familiar faces leads to a very large and significant disruption in recognition performance. In fact, a significantly greater decrement in face recognition is observed in the absence of eyebrows than in the absence of eyes. These results may have important implications for our understanding of the mechanisms of face recognition in humans as well as for the development of artificial face-recognition systems.     

Understanding the Effects of Unemployment in Indian Graduates: Psychological,Financial and Social Perspectives

The present research attempts to examine the psychological impact of unemployment and understand the individual experiences of unemployed Indian graduates. It seeks to address three possible effects of unemployment, which are psychological, financial and social, along with a necessary scrutiny on how these individuals cope with their present unemployed situation. A qualitative analysis method has been employed to investigate the research objectives through employment of a semi-structured interview schedule among graduates in the age group of 21–23 years. The research findings suggest that unemployed graduates are psychologically impacted and sometimes experience feeling of worthlessness, social embarrassment and high level of stress. Some individuals also reported a lack of motivation and meaning in their life. Although, a majority of the participants agreed to have a decline in their psychological well-being, not all share the similar experiences of unhappiness and worthlessness owing to their unemployment. Therefore, this research also hopes to underline differences in the individual experiences due to unemployment.
