Intelligence Flashcards by Shannon O’Leary

What is the Simon and Binet intelligence test?

Created in 1904, the test was used to measure chronological age and mental age in order to stream children in French schools.

What was Henry Goddard’s contribution to intelligence testing?

He brought the Simon-Binet test to the U.S. in 1908 in order to identify “mentally retarded” children. He viewed intelligence as fixed, considering it to be hereditary “feeble-mindedness”.

What were Binet’s assumptions about intelligence?

Intelligence (required to succeed at school) underlies reasoning, thinking, and problem-solving.
Children’s mental abilities increase with age.

15 subtests (10 core, 5 optional)
Items become progressively harder as the test progresses
Determines a profile of abilities, not just IQ

What are some strengths of IQ tests?

Study These Flashcards

Standardised to allow comparison
Scores are consistent for teens and adults (reliable)
Predicts success in school and occupation
Validity is high if test is used appropriately

What are some weaknesses of IQ tests?

Study These Flashcards

Reliability isn’t good before age 7
Can’t predict success in non-relevant areas
Cultural factors have an influence
Other factors can play a role, such as emotional, physical, motivational and problem-solving strategy.

What is the purpose of intelligence testing?

Study These Flashcards

Specific goal - not just to get an IQ score
Predict real-world behaviours/performance
Detect barriers to learning and intellectual disabilities
Develops a profile of strengths and weaknesses

What are some areas to consider in intelligence testing?

Study These Flashcards

What types of tasks to include - what best measures intelligence
Statistical properties of the test - norming
Rules for administering the test
Interpreting the results - scoring

What is norming?

Study These Flashcards

Representativeness of sample
- age
- gender
- ethnicity
- geographic region
- occupation
- urban/rural residence
Needs to broadly represent the population (can be expensive).

What is necessary for administering?

Study These Flashcards

Trained psychologist
Testing situation
Directions
Phrasing
Conversational style
Rapport-building (pre-test)
Time limits
Consistency in presentation order
Terminate task after certain number of incorrect responses

Describe nature and nurture in intelligence.

Study These Flashcards

Influenced partly by genetics - not clear exactly which genes are involved.
Intelligence is developed ability
Influenced partly by environment - education, culture and other life experiences.

What are the findings of adoption studies regarding IQ?

Study These Flashcards

Children whose biological parents were wealthy had higher IQs than children whose biological parents were poor, regardless of the socioeconomic status of the adoptive family.

Summarise the findings of the Duyme et al (1999) study.

``` 65 deprived (neglected or abused) children were selected. Adopted between 4 and 6 years and had an IQ of less than 86 (mean = 77, SD = 6.3) before adoption. Average IQs of children in low SES were 85 and higher SES were 98 at adolescence. Significant gain in IQ dependent on SES of adoptive families. ```

Why does SES affect IQ?

Parents' intelligence influences occupation and status. Income affects the family environment (books, etc.) Motivation differences (higher SES value education more) More opportunities for people with higher IQs.

Summarise the findings of Kaler and Freeman (1994)

``` 25 children (23-50mths) in Romanian orphanage. Romanian orphans with minimal human interaction showed severely delayed cognitive development (particularly in areas of interaction, requesting, play, indicating, self-recognition and social reference). ```

What is Project Head Start?

Program of the USA's department of Health and Human Services that assists children from low-income families - health, nutrition, parent-child relationships, how to enrich environments.

What is Charles Spearman's 2 factor theory of intelligence?

An individual's performance at one type of cognitive task tends to be positively correlated to their performance at other kinds of cognitive tasks. He suggested that these correlations reflected the influence of an underlying general (g) factor. These g factors consist of several specific (s) factors.

What is Louis Thurstone's theory of intelligence?

Thurstone suggested that opposed to just one general ability; there are 7 primary factors.

What are Thurstone's seven primary factors?

1. Numerical 2. Reasoning 3. Verbal fluency 4. Spatial visualisation 5. Perceptual ability 6. Memory 7. Verbal comprehension

What is Raymond Cattell's theory of intelligence?

Distinguished 2 types of general intelligence: fluid intelligence (gf) and crystallised intelligence (gc). Cattell proposed there are 2 g factors with 7 underlying smaller factors

How does Cattell define fluid intelligence?

The capacity to think logically and solve problems in novel situations

How does Cattell define crystallised intelligence?

The ability to use learned knowledge and apply it.

What is the information processing/cognitive model of intelligence?

Focuses on understanding the processes that underlie intelligent behaviour: - the amount of information that can be processed - the speed of the processing - working memory - knowledge/long-term memory - ability to acquire and apply cognitive strategies

What are Gardner's nine multiple intelligences?

``` Linguistic Logical Spatial Musical Body Intrapersonal Interpersonal Naturalistic Spiritual/existential ```

What is an intellectual disability?

Deficit in intellectual functioning (IQ usually below 70 or 75). Usually affects areas of reasoning, problem solving, planning, verbal comprehension, abstract thinking, judgement and quantitative reasoning.

What cognitive characters do individuals with an intellectual disability usually possess?

- Perform certain mental operations slowly - Have a smaller knowledge base - Do not remember to use certain mental strategies even if they know how to (adaptive functioning)

What are some causes of intellectual disability?

Genetic causes - down syndrome, fragile X syndrome | Environmental - rubella, foetal alcohol syndrome, infections

What difficulties does an individual need to have in order to be diagnosed with dyslexia or other intellectual disabilities?

- Inaccurate or effortful reading - Difficulty understanding the meaning of what is read - Difficulties with spelling - Difficulties with written expression - Difficulties with numbers - Difficulties with mathematical reasoning.

Why should IQ tests be used in the classroom?

Test for: - Academic problems - Behavioural issues - Streamlining
