Piaget outlined four stages of cognitive development
Children reach these stages at approximate ages
Children must master each stage before moving on to the next
Individual children may progress through the stages at different speeds, but always in the same order
Piaget believed that younger children do not think the same way as older children
Children must go through stages of cognitive development to achieve the abilities of older children or adults
All children go through the stages in the same order
Piaget's theory suggests that children construct their own knowledge in response to their experiences
Children learn many things on their own without adult intervention
Children are intrinsically motivated to learn and do not need rewards from adults to encourage learning
There are elements of both nature and nurture in Piaget's theory
Nature includes maturation of brain and body, motor skills development, and the ability to perceive, learn, and act
Nurture involves adaptation, where children respond to environmental demands to meet their own goals for survival
Sensorimotor stage: Birth to 2 years old
Infants only know the world through immediate senses: sight, taste, touch, sound, and motor actions
Infants lack internal mental schemata and cannot distinguish themselves from their environment
Infants lack object permanence, failing to see or act on hidden objects
Building knowledge through reflexes like grasping, sucking, and turning head to listen
Pre-operational stage: 2 to 7 years old
Children continue to add or create new schemas during this stage
Children are influenced by sensory information and appearance of things, showing centration and lack of conservation
Egocentrism is prominent, where children struggle to understand others' perspectives
Concrete operational stage: 7 to 11 years old
Children can carry out mental operations, understand conservation, and de-centre to see others' viewpoints
They can complete tasks like class inclusion and the three mountains task successfully
Formal operational stage: Adolescence and beyond
Physical presence of objects is needed for mental operations, like counting using beads
Abstract concepts can be understood, and hypothetical problems can be solved using logical thinking
Ideas can be manipulated mentally, and reasoning deductions can be made without visual examples
Problems are approached systematically and organized, without the need for physical aids
Piaget argued that the inability to conserve is due to centration, where children focus on one dimension and fail to consider other aspects
Children in the pre-operational stage struggle with conservation tasks due to lack of decentration
Conservation tasks involve understanding that things remain constant despite changes in appearance
Children search for hidden objects based on previous visual locations during the pre-operational stage
The inability to conserve is linked to the child's failure to understand constancy despite changes in appearance
Three physical symptoms of perimenopause:
Irregularity in menstruation/menorrhagia (heavy or prolonged bleeding) leading to an eventual cessation of periods
Difficulties with becoming pregnant due to irregular ovulation
Night sweats/hot flushes due to hormonal fluctuations leading to insomnia/sleeping problems
Loss of libido/sex drive often due to vaginal dryness/pain during intercourse
Intellectual development refers to how individuals organise their ideas and make sense of the world in which they live in
Intellectual development at each life stage:
Infancy and early childhood: a period of fast intellectual development
Adolescence and early adulthood: a time when thought processes develop and individuals are increasingly able to use reasoning consistently to come to a conclusion
Middle adulthood: past experiences help individuals think through problems and reach a judgement
Later adulthood: individuals continue to learn, but memory and speed of recall is affected by age
Types of intellectual development:
Language development: essential to organise and express thoughts
Memory: essential for storing and recalling information
Problem solving: need to work out things and make predictions
Moral development: reasoning and making choices about how to act
Abstract thoughts and creative thinking: solve problems using imagination without having to be involved practically
Stages of Language Development:
3 Months: begin to make babbling noises as they learn to control the muscles associated with speech
12 Months: begin to imitate sounds made by carers, such as 'da da'. This develops into using single words
2 Years: begin to make 2-word sentences. Begins to build their vocabulary
3 Years: begin to make simple sentences, like 'I want drink'. This develops into the ability to ask questions. Knowledge of words grows rapidly
4 Years: begin to use clear sentences that can be understood by strangers. They can be expected to make some mistakes with grammar
