Cognition Flashcards
Jean Piaget
Came up with stages that children go through to adults
Stage 1
Sensorimotor stage: from birth to about 2 years old. Interact with the world through processing sensory input and by engaging in motor activities. Development of object permeance (things don’t go away when you stop seeing them). Stranger anxiety
Stages 2-4
Preoperational stage (age 2-7yr) Concrete operational (age 7-11yr) Formal operational stage (11+)
Pre-operational stage (stage 2)
Represent objects symbolically with words or images .
Egocentrism
Difficulty imagining the world from the perspective of others
Centration
tendency to focus on a single property/parameter
Concrete operational stage (stage 3)
Develop and understand conservation, loss of egocentrism, develop logical reasoning skills
Formal operational stage (stage 4)
Abstract logic, can handle hypotheticals, reason abstractly, and make nuanced moral judgements
Schema
EX) cows have black and white splotches and that they produce milk. If you came across a creature with brown instead of black, and with same function, you may conclude…
either cows have other colors (accommodation), or it is not a cow (assimilation)
Fluid-intelligence
Problem-solving skills that can be applied to new situations without any reliance on previously existing knowledge
Crystallized intelligence
The ability to deploy one’s knowledge and skills to solve problems
Dementia
cognitive decline and memory impairments interfere with a person’s ability to function in the world
Trial and error
We try different options and see what works. lack of conceptual understanding. used when we have time and resources
Algorithm
involved applying a fixed set of steps. designed with preparation and insight, application requires no conceptual understanding of the problem
Deductive reasoning
top-down in nature, applying general principles to a specific situation
