Language development is relative to cognitive development – development of a child’s thinking determines when and what the child can speak. i.e. “This car is bigger than that car.” Child must have developed the ability to differentiate size Children learn to talk “naturally” when they are “ready” without deliberate teaching by adults
Four stages • Sensori Motor (birth – 2 years old) • Differentiates self from objects • Begins to act intentionally • Begins to realize that there are objects that are not seen or visible to them.
Pre- Operational (2-7 Years old) • Learns to use language to represent objects by image and words • Egocentric • Classifies objects by single features
Concrete Operational (7-11) • Thinks logically about objects and events • Has a sense of numbers • Classifies objects according to features and can order them in series along a single dimension such as size
Formal Operational (11 and up) • Thinks logically about abstract propositions and tests hypotheses systematically. • Becomes concerned with future, ideological problems.
Challenges • Two pieces of evidence that refute: • One – development does not always progress in the smooth manner the theory seems to predict ‘decalage’ . • Two – They are domain general, cognitive maturation occurs concurrently across different domains of knowledge
