Schema describes both mental and

physical actions involved in understanding

and knowing. Schemas are knowledge that

help us to interpret the world.

The term schema was introduced by

Piaget in 1926.

The concept was introduced by British

Psychologist Frederic Bartlett.

Studies were carried out on reconstructive

memory and participants found that

previous or existing schema influenced

how they recalled information.

He proposed that people cannot perform

certain tasks until they are mentally mature

enough to do so.

And that children's’ thinking moves to new

capabilities at some points.

So before certain ages, no matter how

clever a child is, he will not be able to

understand things in certain ways.

Person schema about attributes of a particular individual.

Event schema for practices and tasks caused by stimuli.

Role schema, how we expect people performing a certain role to perform.

Self-schema, memories of past experiences and present situations.

For fast continuous movements

Decisions are made in the brain

The information for one movement is sent

The message is received by the muscles

in order for them to perform the movement

Usually there is no feedback

For slow movements.

Again, decisions are made in the brain.

Information is sent in segments.

Information is received by muscles for the

movement.

Feedback is available and is needed to

correct movement patterns.
