Module 2 - Child development Flashcards
what is development ?
the sequence of physical and psychological changes that human beings undergo as they grow older
what is developmental psychology
the scientific study of age-related changes in behaviour, thinking, emotion, and personality.
what is cognition development ?
intellectual growth
who was the father of cognitive development ?
jean piaget
what did jean piaget do ?
Proposed a sequence of development that all normal children follow
- Four ‘stages’ of cognitive development
what age is the sensorimotor stage
Birth to 2 years
what does the sensorimotor stage include?
- object permanence
- schema formation
- representational thought
what is object permanence
the idea that objects do not cease to exist when they are out of sight
- Birth – 3 months - Look at visual stimuli Turn head towards noise - 3 months - Follow moving objects with eyes. Stares at place where object has disappeared, but will not search for object - 5 months- Grasp and manipulate objects Anticipate future position of object - 8 months Searches for hidden object “A not B” effect- ( search for the same place they found it not where they saw it last) - 12 months - Will search in the last place they saw the object
what is schema formation ?
a schema is a mental representation or set of rules that defines a particular behaviour category. It helps us to understand current and future experiences
describe the 2 process that schema develops
Assimilation – the process by which new information is modified to fit in with an existing schema - i.e knows dog and cat are animals but sees a rabbit and calls out “doggy”
- Accommodation – the process by which an existing schema is modified or changed by new experience. (i.e when he is told that it is not a doggy but a rabbit, the next time he will say rabbit, hence once more added to the schema of animals
what is representational thought ? when does it occur
ability to form mental representations of others’ behaviour.
- Occurs towards the end of the sensorimotor period
- Mental representation is instrumental in: - Imitation - Deferred imitation - a child’s ability to imitate the actions he or she has observed others perform in the past - Symbolic play - The use of words to represent objects
what age is preoperational stage
2- 7 yeards
what happens in the preoperational stage
- Ability to think logically as well as symbolically - crappy logic
- Rapid development of language ability
- Counting
- Object Manipulation
- Classification and categorisation
what to infants need to learn in the preoperational stage to move to the next
- Conservation – the understanding that specific properties of objects (height, weight, volume, number) remain the same despite apparent changes or arrangement of those objects.
- Egocentrism – a child’s belief that others see the world in precisely the same way that he or she does
what age is the concrete operation stage
7 to 12 years
what happens in the concrete operation stage ?
- Ability to perform logical analysis - they can’t go hypothetical
- Ability to empathise with the thoughts/feelings of others
- Understanding of complex cause-effect relations -
what age is the formal operation stage ?
12 years and upward
what happens in the formal operation stage?
- Abstract Reasoning - they would say I could imagine rocky, lonely dark hence hypothetical
- Metacognition - i.e studying - memorising - thinking about thinking
- Dependent on exposure to principles of scientific thinking
name the 4 stages
- sensorimotor stage
- preoperational stage
- concrete operations stage
- formal operations stage
what were the 2 criticism on on piagets theory
- babies don’t seem to start with nothing
2. Cognitive development isn’t on all or nothing phenomenon
what ideas supported the criticism babies don’t seem to start with nothing ?
- space and objects
- number and mathematical reasoning
- social cognition - our understanding of other people
explain the idea space and objects?
o The Visual Cliff
Children appear to be able to perceive depth around the time they can crawl
o The Effect of Occlusion
Habituation procedure
- Infants prefer to pay attention to novel things
- Over time they become accustomed to stimuli and pay less attention to them
o Understanding of Support
Develops gradually by 6 months - over six months they gradually show understanding
o Object Permanence
- If you don’t see the object, it does not mean it does not exist - Remember the “A not B” error? - they look for the object where they found the object and not where they last put it.
explain the idea o fnumber and mathematical reasoning?
Piaget said that infants had no concept of number and couldn’t conserve number until they were around 6 years old
o But even 6-months old show some understanding of number
i.e you show child 3 pieces of things and 2 pieces of things and you put a speaker and the speaker does “boom” “boom” the child will look at 2 pieces of things but if the speaker does boom X3 then the child will look at 3 pieces of things
explain the idea of social cognition - our understanding of other people
o New born babies would rather look at faces than scrambled faces
o At 3 weeks old, infants will attempt to imitate facial expressions
o 9-month-olds will look in the direction of their mother’s gaze
o Intentions - what adults tend to do or trying to do
- Even 6-month-olds understood that the object being reached for is separate to the reach itself
