Contrast the views of Piaget and Bandura on how children develop. Solution Piaget\'s theory of child - cognitive development: According to Piaget, cognitive reversibility is a tangible operation state in which children initially habituate and gain knowledge to understand the things how it works and alter they gain knowledge to return to their original state. Paiget illustrated children’s cognitive development in four stages They are 1. Sensory motor stage 2. Pre-operational stage (2 to7 years of old) 3. Concrete operational (children of 7 to 11 years old) 4. Formal operations (11 to 16 years adolescence stage) Preoperational stage defined as the stage at which children mainly habituate and gain knowledge to speak at the age of 2 to 7 years. In this stage child develops to use symbols initially and finally form enduring and manipulating symbols. In this stage, children do not develop logical thinking or reasoning. In concrete operational stage, children often develop logical thinking and efficient cognitive abilities. Preoperational stage includes the following stages of features such as a. animism; b. artificialism c. transductive reasoning. According Piaget conservation has illustrated as the process in which children at the age of 2 to seven are unable to think logically. But their logical thinking starts at the age of seven to eleven years. The formal operational stage starts after 11 years in which children often learn about mathematical models and apply them to solve a variety of problems. According to Bandura, children learning perspective is mainly associated with anticipated outcomes based on observational learning where environmental cues has specific impact on them. Behavioral cognitive theory: According to Bandura, behavior is resultant response due to complex interplay between environmental cues & inner processes in any species finally attain empirical validity. As per cognitive theories behavioral concern always involves a variety of environmental stimulus and concerned response, it could be voluntary response or reflexive response. These responses are associated with cues. This behavior is mainly based on external rewards through cortico-striatal pathway..
