Cognitive Development Flashcards
What is cognition?
Describes the mental processes that lead to knowledge, understanding and awareness - covers topics such as attention, learning, memory and consciousness
What does cognitive psychology aim to explain?
How we:
1. perceive our environment
2. memorise information
3. use language to communicate
4.interpret the behaviour of other people
5. understand numbers
6. solve problems using logic
7. make decisions
What skills are developed over time?
Language, knowledge and procedural skills
What four stages in did Piaget say develop adult level cognition?
Sensorimotor (0-2), pre-operational (2-7), concrete operational (7-12) and formal operational (12+)
What is each stage of Piaget’s stages characterised by?
Observable skills that children demonstrate at different ages
What occurs in the sensorimotor stage?
Children have sensory experiences and can interact with objects. They learn through physical movements and sensations. At first, they cannot distinguish between themself and their surroundings and do not have a solid concept of object permanence.
What occurs in the pre-operational stage?
Children start to develop mental imagery and language proficiency. They are egocentric and don’t understand that objects look different from different angles or that people can hold different beliefs. They cannot perform mental operations to solve problems - glass of water example
What occurs in the concrete operational stage?
Children begin to understand that their viewpoint is only one of many - they can use logical operations but only when problems are concrete. They cannot solve abstract problems that are not situated in reality
What occurs in the formal operational stage?
Adolescents can solve problems on a purely mental level and they can use deductive reasoning and understand abstract ideas. They can understand that problems need to be solved in a systematic way. Less rigid in their thinking - can see multiple solutions
How have times changed since Piaget did his work?
Theory first appeared in 1936 and scientific methods and standards have evolved - Piaget studied his three children with no statistics or clear study design
What three areas of cognitive development were mentioned in Piaget’s theory?
Object permanence, theory of mind and abstract thinking
What is object permanence?
The knowledge that objects are permanently in existence as they do not time travel or teleport - they have temporal and spatial contiguity
Why is object permanence an important cognitive skill?
Understanding that objects are continuous is the basis for understanding more complex interactions in the world - e.g. allows us to perceive causal events or intentionally in the movement of simple shapes
When does object permanence develop according to Piaget?
Piaget argued that infants do not object permanence until around 8-9 months as he objeservd younger children will not search for an object when it is hidden but it is also possible that younger children cannot yet perform coordinated actions with objects
When does object permanence develop according to experimental work?
Infants can understand that objects continue to exist when they are not visible from each earlier in their first year, around 3.5 months - studies using looking times to probe infant’s knowledge without relying on language
What can be inferred about looking times?
If they observe different looking times such as longer fixations, then the researcher can infer that the infants can tell the difference between the conditions
Why do infants look for longer during the impossible events ?
Infants are often drawn to new and unfamiliar stimuli which is called a novelty preference. They also lose interest in familiar input - they become habituated. It is possible that they show this novelty bias because they are trying to learn new information from an unfamiliar input
