2What is cognitive development?
- Expressed by (Berk. 2004) as children actively
construct knowledge as they manipulate and
explore their world. - Cognitive Development has been categorized into
four main stages when dealing with children,
these were founded by the main theorist for this
topic, Jean Piaget.
3Stage one of cognitive development
- 1 Sensori-motor period (0-2 years)
- Actions are performed on the world in terms of
their five senses. Initially the childs
behaviour is governed by simple reflexes. This
stage is sub-staged into six parts.
The child cannot understand that the toy is
still there even though it has been covered by a
sheet of paper
4The sub-stages
- Substage 1 (0-1 months) modification of reflexes
- Substage 2 (1-4 months) primary circular
reactions - Substage 3 (4-8 months) secondary circular
functions - Substage 4 (8-12 months) coordination of
secondary reactions attainment of object
performance - Substage 5 (12-18 months) tertiary circular
reactions - Substage 6 (18-24 months) representational
thought
5Stage two of cognitive development
- 2 Pre-operational stage ( 2-7 years)
- The emergence of language, modelling and memory
are key features. It is in this when, that
according to (McGurk. 1975, p.36-37) the childs
internal, cognitive representation of the
external world is gradually developing and
differentiating but many serious limitations are
also in evidence.
6Stage three of cognitive development
- 3 Concrete operations period (7-11 years)
- According to Piaget, this stage is when children
begin to understand the relationship between
things in the world but still cannot think in
abstract terms. Although their thinking has
greater flexibility, they are capable of
operational groupings only with concrete objects.
if you have two five inch sticks laid parallel to
each other, then move one of them a little, the
child may believe that the moved stick is now
longer than the other.
7Stage four of cognitive development
- 4 Formal operations period (11 years)
- The individual moves from a less to a more mature
level of functioning. McGurk(1975, p. 39) notes
that the hallmark of this stage is the childs
ability to reason abstractly without relying upon
concrete situations or events.
8Cognitive development in infancy
- In the first 18 months of life, infants are
maturing not only physically but cognitively as
well. Piaget describes the first two years of
life as a time of rapid growth in the childs
ability to think, reason and understand the
world. (Slee,P. 2002, p.142-143). Infants belong
within the Sensori-motor period in which they are
using their sensory systems and motor activity to
help them to acquire knowledge about the world.
9Cognitive development in early childhood
- Belong in the Pre operational stage of
development. - most obvious change is an extraordinary increase
in representational, or symbolic activity.
(Berk. P.216, 2004) - Eg. The child pushes the block along the floor
saying broom broom, they know that the block is
not a car but the block signifies something to
the child.
10Cognitive development in middle childhood
- During Primary school years, children make
significant strides in terms of their cognitive
development. - Piaget places them within the concrete operations
period. - Children begin to understand the relationship
between things in the world but still cannot
think in abstract terms (Slee,P. p.331, 2002) - Thought is more logical, organised and flexible
than in early childhood.
A child in middle childhood will know that If you
pour the mild from the short, fat glass into the
tall, skinny glass, that there is the same amount
of milk as before, despite the dramatic increase
in mild-level!
11Cognitive development in later childhood
- Piaget places these individuals in the Formal
operational stage where these children develop
the capacity for scientific abstract thinking. - In this stage children progress dramatically in
the way of understanding and having the ability
to think in a mature and sophisticated manner.
12Other cognitive processes
- Piaget also included accommodation, assimilation
and organization in his theory of cognitive
development. - Accommodation adapting to the environment
- Assimilation incorporating experiences into
cognitive structures - Organization the way cognitive acts are grouped
and arranged to form sequences, mental folders
or schemata.
13Jean Piaget
- Piagets proposal of the four stages of cognitive
development created a revolution in the study of
cognitive development. - During the 1970s and the 1980s his study
dominated the study of any other theorist and put
new meaning to the childs acquisition of early
literacy and numeracy skills.
14Jean Piaget was born in Neuchâtel, Switzerland,
on August 9, 1896 . (C.George Bueree para.1,
2006)
Piaget proved to quite accurate in his study of
cognitive development as this graph shows. The
only problem with his study is that it was
biased. Most of his experiments were performed on
his own children and not on a variety of
different children from all walks of life.
15Lev Vygotskys Cognitive theory
- His research stretched from 1896 till 1934
- Stressed the significance of the environment and
culture in the learning process. - Disagreed with Piagets view on the structures of
cognitive development. - Argued that childrens cognitive abilities were
formed and progressed by interacting with the
environment. - Scaffolding, or teacher-guided learning of
repeated or relevant behaviour, is one of his key
concepts. - He was born in the same year as Piaget in Russia
16 For him, the individuals development is a
result of his or her culture. Development, in
Vygotskys theory, applies mainly to mental
development, such as thought, language and
reasoning process. These abilities were
understood to develop through social interactions
with others (especially parents) and therefore
represented the shared knowledge of the culture.
He states Every function in the childs
cultural development appears twice first,
between people (interpsychological) and then
inside the child (intrapsychological). This
applies equally to voluntary attention, to
logical memory, and to the formation of ideas.
All the higher functions originate as actual
relationships between individuals (Vygotsky,
1978, p.57). (Sólrún B. Kristinsdóttir, para.1,
2001)
17Theories and todays understanding
- In the 21st century when trying to define the
theory of cognitive development Piaget is the one
whose detailed and extensive theory stands out
amongst the others. - Although his experiments were biased and he faced
many constraints when trying to conduct his
study, his final analysis in the topic proves to
be the most accurate and still taught as THE
theory of cognitive development in schools today.
