4 - Developmental Stages Flashcards
Cognition, Implicit and Explicit
Cognition
- the capacity to think, reason and use knowledge about the world
Explicit cognition
- cognition that you are aware of (can describe in words, literal things)
Implicit cognition
- knowledge you may not be able to describe in words (intuitions, inferences we can make about the world
Piaget’s view on cognitive development
Cognitive Development based on modifying one’s Schemata, adapting it to one’s needs
- noticed common mistakes among age groups
> and differences between age groups
Piaget’s main tenet:
- the child actively seeks knowledge
> Constructionist View:
> children construct their own understanding, trying to fit new information into what they already know
- systematic changes in children’s thinking occurs at certain ages
Piaget’s theory on Cognitive Organisation
- child’s knowledge gets organised into increasingly more complex structures
- Schema
> child’s knowledge, representations and ways of interacting with the world - Adaptation
> Assimilation
+ interpreting new experiences in terms of existing schemes
> Accommodation
+ altering schemes in response to new experiences
> Equilibration
+ assimilation and accommodation working together
What is a Schema?
An individual’s knowledge, representations and ways of interpreting the world and interacting with it
What is Cognitive Adaptation?
(Piaget)
The process by which an individual’s cognitive ability develops
3 Processes:
- Assimilation
> interpreting new experiences in terms of existing Schemes
- Accomodation
> altering existing schemes in response to new experiences (if they do not fit the schema) - Equilibriation
> the combination of Assimilation and Accommodation working together
Piaget’s Model of Cognitive Development and the 4 Stages
First detailed model of development ever made
- stresses Domain-Generality (concepts develop by elaborating and integrating schemes {qualitative stage theorist})
- Sensorimotor Period (0-2)
> infants distinguish their own bodies and actions from the external world - Pre-operational Period (2-7)
> can use symbols to mentally represent objects, can’t see quasi-logical relations - Concrete Operational Period (7-12)
> can apply quasi logical operations, can’t think abstractly - Formal Operational Period (12+)
> can think logically about hypothetical and abstract ideas
Substages of the Sensorimotor Period (6)
0-2y
Reflexes (0-1m)
- reflexes become more efficient (i.e. sucking)
- no awareness of objects in the world
- no ability to integrate information from different senses
Primary Circular Reactions (1-4m)
- PCR = discovers by chance that they can interact with an object using reflexes
- will then reproduce the action and improve at it
- no object permanence
Secondary Circular Reactions (4-8m)
- SCR = applying new schemes to external objects
- still happens by chance but now related to objects
- some level of object permanence
Integration (8-12m)
- integration of secondary schemes
- more complete understanding of an object and how they can interact with it
- shows A-not-B error
Tertiary Circular Reacitons (12-18m)
- TCR = applying schemes intentionally
- begin to understand objects exist independent of schemes
- succeeds at A-not-B error
- fails at invisible displacement
Stage 6 (18-24m) - flexible use of schemes - fully developed object permanence > passes the invisible displacement task - begins to use language
Testing the accuracy of Piaget’s Sensorimotor stage (2)
A-not-B error
- Piaget believed this showed that children do not represent the hidden object appropriately
- in fact:
> if the cover is transparent, children still make the mistake, indicating it is not an error of the object being hidden
> children still tend to look at the correct cover, even when reaching for the incorrect one (reaching error)
+ patterns of looking behaviour may be a better way of measuring A-not-B behaviours
Baillargeon’s Results:
- children as young as 3.5m show object permanence
- found this via Expectations Violation
> familiarising the baby with a process, then introducing something that would prevent the process (i.e. blockade), but (unseen to the baby) removing it to allow the process, then reinstating it to show it is still there
+ caused the infants to stare longer at the problem, indicating they were confused, or had realised the problem was complex, indicating object permanence
Substages of the Pre-Operational Period (2)
Pre-conceptual substage (2-4y)
> imaginative play
> animistic thinking (attribute life to inanimate objects, difficult differentiating live and inanimate objects)
> Egocentric thinking (inability to de-centre from their own perception)
+ tested by the three mountain task
- Intuitive substage (4-7y)
> children can solve problems but can’t explain how
> difficulty with part-whole relations (class inclusion)
+ differentiation between an item within it’s class i.e. dogs within animals
Thinking in the Pre-operational Period
- Development of Symbolic thinking (facilitates use of language)
Pre-operational thought:
> child is semi-logical, conservation skills not yet complete (child understands quality (shape) but not quantity (volume) if an object)
> reversibility not understood
- poor Transitive inferences
> ability to remember information to help solve a problem
Concrete Operational Stage (1)
7-12y
- child is able to reason logically about physically present objects
> able to de-centre
> increased understanding of reversibility
> ability to classify increases
> cultural differences in this
Formal Operational Stage (1)
12y+
- children able to engage in abstract, complex reasoning and hypothesis testing
> not all thinking confined to reality
> not all people in all cultures reach the Formal Operations stage (stage is strongly tied to cultural influences)
Piaget’s view on the importance of object permanence
- object permanence has implications for development of self-recognition
Piaget’s view on the importance of self-distinction
- self distinction from others is central to development of social cognition
Piaget’s view on the importance of egocentrism
- decreased egocentrism allows role-taking
> also may improve communication and empathy
