Role of environment in child development is best reflected by ________.

The environment as well genetic factors both play a major role in the development of an individual. This influence forms the personality of a child.

Key Points The role of the environment in child development is best reflected by Habit formation. The theories of behaviorism by Pavlov, Skinner, and Thorndike and social learning theory by Bandura describe this.

• Temperamental tendencies - These are the natural tendencies that are inherent in the personality of an individual and have less role in the environment.
• Personality disposition- .Studies of behaviour genetics suggest that most personality variables are 15 to 50 percent inheritable.
• Primary reaction patterns- These are the reflex and involuntary or voluntary patterns of actions exhibited by a baby irrespective of the environment.​

Hence, we conclude that role of the environment in child development is best reflected by Habit formation.
