Unit 1 "cognition" Flashcards
Define Intelligence (1) mark
The global capacity to act purposely, think rationally, and deal effectively with the environment (David Weschler)
Also, abstract thinking or reasoning, problem-solving ability, memory, capacity to acquire knowledge and adaptation to one’s environment. (Snyderman & Rothman, 1987)
What are 2 problems with defining intelligence (2) marks
-Intelligence cannot readily be observed…
1884 Galton: tried to measure intelligence through “simple tests” i.e head circumference
-Non-cognitive tasks can show intelligence but are not ‘counted’, e.g. music, dance, practical skills.
What is Galtons theory of general intelligence (3) marks
- believed a person’s success was due to superior qualities being ‘handed’ down by heredity.
- noted the importance of individual differences.
- Intelligence is a general ability, showed in different ways and dependent on the environment.
- Believed intelligence could be measured using simple tests
- first to use questionnaires as tests of mental ability
What is factor analysis (1) marks
a complicated statistical method measuring cognitive abilities and their relationship to other attributes Eg: school or job success
Explain Spearman’s two factor theory (2) marks
proposed that intelligence consisted of two factors: general factor and specific factors
- General factor – underlying intelligence factor
- Specific factor - specific skills, unique abilities (eg mechanical, mathematical or verbal skills)
Who was the first theorist to use questionnaires as tests of mental ability (1) mark
Galton
Define Alfred Binet’s theory of general intelligence (1) mark
Intelligence is seen in a range of mental abilities (reasoning, perception, imagination)
Who developed the first standardised intelligence test (1) mark
Alfred Binet (1905)
What was the purpose of Binet’s standardised intelligence test (1) mark
To differentiate ‘normal’ kids from ‘special needs’
Explain the 1905 Binet-Simon intelligence scale test (3) marks
-30 questions measuring a range of mental abilities such as,
Naming objects, common knowledge, memory, counting exercises
-Arranged in increasing difficulty
Classified people into three groups - Idiots (most deficient), morons or imbeciles (least deficient).
What 3 things do do IQ scores depend on (3) marks
- Test
- Participants
- Conditions
What was calculation for IQ proposed William Stern (1) mark
IQ= mental age / Chronological age X 100
How was the Binet test further developed to the Standford- Binet intelligence scale of 1916
(2) marks
Lewis Terman developed the original Binet test further
Which made the Binet-Simon test more appropriate to Americans.
And extended the test so it was more appropriate for adults.
What were the Five cognitive areas (verbal and non-verbal) of the Binet Intelligence Test (3) marks
Fluid reasoning Knowledge Abstract Visual-spatial Reasoning Quantitative Reasoning Short-Term Memory (working memory)
Factors of the Alfred Binet intelligence scale test (3) marks
Age-related
Questions ordered from least difficult to most difficult
Test trialled on a large number of children of different ages
Fair if 65-75% could answer correctly
Test administered individually
What is Mental Age (1) mark
Mental Functioning
What is chronological age (1) mark
Actual age
Explain The Raven Test (2) marks
is a non-verbal ‘culture fair’ multiple choice IQ test, that measures your fluid intelligence your reasoning and problem solving ability.
