Cognition

Question 1

What is cognition?

Answer 1

the study of how our brains process and react to the incredible information overload presented to us by the world

Question 2

What are the four pillars of information processing model?

Answer 2

(1) Thinking requires sensation, encoding and storage of stimuli
(2) Stimuli must be analysed by the brain to be useful in decision making
(3) Decisions made in one situation can be extrapolated and adjusted to help solve new problems
(4) Problem solving is dependent not only on the person’s cognitive level, but also on the context and complexity of the problem

Question 3

What is Jean Piaget known for?

Answer 3

Stages of cognitive development - insisted that there are qualitative differences between the way that children and adults think

What is assimilation?

Answer 5

process of classifying new information into existing schemata

Question 6

What is accommodation?

Answer 6

process by which existing schemata are modified to encompass this new information

What is the stages of Piaget’s Cognitive Development?

Answer 7

(1) Sensorimotor
(2) Preoperational
(3) Concrete operation
(4) Formal operational

Question 8

What is the sensorimotor stage?

Answer 8

Birth - 2 years of age
Child learns to manipulate his or her environment in order to meet physical needs; ends with the development of object permanence

Question 9

What are primary circular reactions?

Answer 9

the repetition of a body movement that originally occurred by change (ie. sucking thumb)

Question 10

What are secondary circular reactions?

Answer 10

manipulation is focused on something outside the body (ie repeatly throwing toys from a high chair)

Question 11

What is object permanence?

Answer 11

the understanding that objects continue to exist even when out of view

Answer 15

refers to the inability to image what another person may think or feel

Question 16

What is centration?

Answer 16

the tendency to focus on only one aspect of a phenomenon or inability to understand conservation

Question 17

What is the concrete operational stage?

Answer 17

7 yrs - 11 yrs

Can understand conservation and consider the perspective of others; engage in logical thought with concrete information

Question 18

What is the formal operational stage?

Answer 18

11 yrs - end of life
Marked by the ability to think logically about abstract ideas; ability to reason about abstract concept and problems solves

Question 19

What is Lev Vygotsky known for?

What is trail-and-error?

Answer 27

a less sophisticated type of problem solving in which solutions are tried until one is found that seems to work

Question 28

What is an algorithm?

Answer 28

a formula or procedure for solving a certain type of problem

Question 29

What is deductive reasoning?

Answer 29

aka "top down" - starts from a set of general rules and draws conclusions from the information given

What is inductive reasoning?

Answer 30

aka "bottom up" - theory through generalizations; starts with specific instances and then draw conclusions

Answer 31

simplified principles used to make decisions; "rule of thumb"

What is the availability heuristic?

Answer 32

used when we try to decide how likely something is

Question 33

What is a representativeness heuristic?

Answer 33

involves categorizing items on the basis of whether they fit the prototypical, stereotypical, or representative image of the category

Question 34

What is the base rate fallacy?

Answer 34

using prototypical or stereotypical factors while ignoring actual numerical information

Question 35

What is the disconfirmation principle?

Answer 35

when a potential solution fails during testing and should be discarded

Question 36

What is confirmation bias?

Answer 36

the tendency to focus on information that fits an individual's beliefs, while rejected information that goes against them
