# Piaget's Concrete Operational Stage

PSYB3 - COGNITIVE DEVELOPMENT

HideShow resource information

## Introduction

• 7-11 years
• Logical thought processes are still limited to thinking about concrete objects and problems. eg. a child can think about fractions in relation to real objects such as a cake cut into quarters, but cannot perform abstract mathematical operations.
• Examples of Logical Thought in Concrete Operational Child: Conservation, Compensation, Serial ordering, Transitivty, Class Inclusion

## Conservation

Understanding that properties of objects and materials can remain the same despite changes in outward appearance

2 of 6

## Compensation

Understanding that one feature can compensate for another

3 of 6

## Serial ordering

(Seriation) - Organising concrete objects into order. eg. ordering seven sticks of different lengths from shortest to longest

4 of 6

## Transitivity

(Mental Seriation) - Making inferences on the basis of information given. eg. knowing that stick A is longer than stick B, and stick B is longer than stick C, the child could reason that stick A must be longer than stick C

## Class Inclusion

Distinguishing between superordinate and subordinate categories
