Piagetian stages

Question 1

StageSensorimotor

Answer 1

StageSensorimotor
agebirth to 18-24 months
Features
Inborn motor and sensory reflexes
Primary Circular Reactions
Secondary Circular Reactions
Use of familiar means to obtain ends
Tertiary Circular Reactions and discovery through active experimentation
Insight and object permanence

Question 2

Preoperational

Answer 2

age2-7 years
Features
Deferred imitation
Symbolic play
Graphic imagery (drawing)
Mental imagery
Semiotic function (ability to use symbols)
Language.                                             In the preoperational stage, children use symbols and language more extensively. They are unable to think logically or deductively, and events are not not linked by logic.

During this stage, children also use a type of magical thinking, called phenomenalistic causality, in which events that occur together are thought to cause one another (e.g., thunder causes lightning). In addition, children use animistic thinking, which is the tendency to ascribe life to inanimate objects.

The semiotic function emerges during the preoperational period. This enables children to represent something such as an object, an event, or a conceptual scheme with a signifier (symbol). That is, children use a symbol or sign to stand for something else.

Question 3

Concrete operational

Answer 3

age7-11 years
Features
Egocentric thought replaced by operational thought (child now deals with information outside them)
Syllogistic reasoning (logical conclusions formed from two premises).
Conservation of number (age 6), mass (age 7), distance (age 8), volume (age 9), classifies objects by several featuress. In the concrete operational stage, egocentric thought is replaced by operational thought, which involves dealing with a wide array of information outside the child. Therefore, children can now see things from someone elses perspective.

Children in this stage begin to use limited logical thought and can serialise, order, and group things into classes on the basis of common characteristics. Syllogistic reasoning, in which a logical conclusion is formed from two premises, appears during this stage. For example , all horses are mammals (premise); all mammals are warm blooded (premise); therefore, all horses are warm blooded (conclusion).

Conservation is the ability to recognise that, although the shape of objects may change, the objects still maintain or conserve other characteristics that enable them to be recognized as the same. For example, if a ball of clay is rolled into a long, thin sausage shape, children recognize that each form contains the same amount of clay.

Reversibility is the capacity to understand the relation between things, to realize that one thing can turn into another and back again (e.g. ice and water).

Question 4

Formal operational

Answer 4

age11 years to adolescence
Features
Thinks logically and tests hypotheses. This stage is characterized by the ability to think abstractly, to reason deductively, to define concepts, and also by the emergence of skills for dealing with permutations and combinations. Young people can grasp the concept of probabilities.

Hypotheticodeductive Thinking, the highest organization of cognition, enables a person to make a hypothesis or proposition and to test it against reality. Deductive reasoning moves from the general to the particular and is a more complicated process than inductive reasoning, which moves from the particular to the general.

Question 5

Sensorimotor Stage (Birth to 2 Years)

Answer 5

AgeBirth - 2 months
DescriptionUse of inborn reflexes (grasping, sucking, and looking) to interact with and accommodate the external world.
Age2 - 5 months
DescriptionPrimary circular reactions. Co-ordinates activities of own body and senses (thumb sucking). Reality remains subjective (does not seek stimuli outside of visual field. Displays curiosity.
Age5 - 9 months
DescriptionSecondary circular reactions. Seeks out new stimuli in the environment. Starts to anticipate consequences of own behaviour and to act purposefully to change the environment. Beginning of intentional behaviour.
Age9 - 12 months
DescriptionShows preliminary signs of object permanence. Has vague concept that objects exist apart from itself. Plays peek-a-boo.
Age12 - 18 months
DescriptionTertiary circular reactions. Seeks out new behaviours and produces novel behaviours.
Age18 - 24 months
DescriptionSymbolic thought. Uses symbolic representations of events and objects. Shows signs of reasoning (uses one toy to reach for and get another). Attains object permanence.

Question 6

Circular reaction

Answer 6

A circular reaction is a behavior that produces an event (thumb brushes mouth, kicking moves a rattle) that leads to repetition of the behavior.

Primary circular reactions involve only the infants own body.

Secondary circular reactions are like primary, only the behavior involves external objects (e.g. shaking a rattle).

Tertiary circular reactions involve experiments with the different kinds of effects the same behavior can have (e.g. bouncing a ball down stairs then bouncing lots of other things down stairs).

Question 7

Precausal thought

Answer 7

Precausal thought is a feature of the preoperational stage of development. It is charcterised by:-

Animism

Animism refers to a child�s tendency to give life and personality to objects. For example when asked “why does string unwind?”, they may answer “because it got tired”.

Transductive reasoning

This refers to a child�s tendency to ascribe personal significance to unrelated events. For example when asked “why does lightening happen?”, they may answer “it’s because we get angry”.
