Prevalence of Principles of Piaget's Theory Among 4-7-year-old Children and their Correlation with IQ.

INTRODUCTION

Cognitive development is a major area of human development and was extensively studied by Jean Piaget. He proposed that the development of intellectual abilities occurs in a series of relatively distinct stages and that a child's way of thinking and viewing the world is different at different stages.

AIM

To assess Piaget's principles of the intuitive stage of preoperational period among 4-7-year-old children relative to their Intelligence quotient (IQ).

MATERIALS AND METHODS

Various characteristics as described by Jean Piaget specific for the age group of 4-7 years along with those of the previous (preconceptual stage of preoperational period) and successive periods (concrete operations) were analysed using various experiments in 300 children. These characteristics included the concepts of perceptual and cognitive egocentrism, centration and reversibility. IQ of the children was measured using Seguin form board test. Inferential statistics were performed using Chi-square test and Kruskal Wallis test. The level of statistical significance was set at 0.05.

RESULTS

The prevalence of perceptual and cognitive egocentrism was 10.7% and 31.7% based on the experiments and 33% based on the interview question. Centration was present in 96.3% of the children. About 99% children lacked the concept of reversibility according to the clay experiment while 97.7% possessed this concept according to the interview question. The mean IQ score of children who possessed perceptual egocentrism, cognitive egocentrism and egocentrism in dental setting was significantly higher than those who lacked these characteristics.

CONCLUSION

Perceptual egocentrism had almost disappeared and prevalence of cognitive egocentrism decreased with increase in age. Centration and lack of reversibility were appreciated in most of the children. There was a gradual reduction in the prevalence of these characters with increasing age. Mean IQ score of children who possessed perceptual egocentrism, cognitive egocentrism and egocentrism in dental setting was higher.
