Some important skills of the sensorimotor period
Object permanence1. No search2. Search for partially hidden object3. Search in first hiding place of object
(Perseveration or A not B error)4. Search only if the hiding of the object in
a particular location is witnessed5. Full object permanence

David Elkind – Adolescent Cognition
Elkind’s discussion of adolescent thought processes focuses on the limited formal skills of the adolescent combined with even lesser developed emotional skills.
Upon observation, this leads to an immaturity of thought that is largely unique to and very common during adolescence.

Piaget’s theory in perspective
The field of Developmental Psychology owes to Piaget the current understanding of children as active and constructive thinkers who act upon and adapt to their worlds.
However, Piaget’s theory has also been modified by contemporary cognitive psychologists in response to newer research findings.

Vygotsky’s theory of cognitive development
Vygotsky viewed children as social creatures who benefited from interacting with the others in their environments.
Vygotsky proposed 2 concepts through which he explains the development of cognition.
1. The zone of proximal development (ZPD)
2. Scaffolding

The role of language
Piaget vs. VygotskyAccording to Piaget, children’s self-talk is a
sign of their egocentrism and immaturity.
Vygotsky views self-talk (private speech) as having a significant contribution to thinking and reasoning. He says that
private speech helps children to plan, to guide, and to monitor their behaviors.

Post – formal thought?
Piaget claims that formal operational reasoning is the highest level of reasoning that can be achieved. While adults may have more knowledge than adolescents said Piaget, the quality of their reasoning is similar.
Contemporary research findings indicate that many adults do not use formal reasoning, especially in relation to everyday problems and situations they encounter.
