Answers.
experts have more narrow defintion that is driven by motivation.
Lay people have more broad defintion that is driven by intrapersonal aspects but their
definitions change over the course of development.
they both defined problem solving, verbal ability and social competence as important. -
ANSWER- What is the difference between the lay public and expert definitions of
intelligence?
They reflect personal definitions and assumptions about IQ.
They emphasis interpersonal skills + perspective taking + social competence.
they are affected by age of person, background and culture. - ANSWER- What are lay
theories of intelligence and what are they affected by?
1) Galton: higher intelligence = higher sensory abilities.
2) Binet: disagreed. said multiple components of intelligence. reasoning, judgement,
memory and abstraction.
3) weschler: intelligence includes verbal and perfromance abilities.
4) piaget: intelligence evolving bio adaption to outside world.
5) spearman: said IQ tests had overlap (general intellectual ability "g")
6) Gardner: said traditional IQ tests only measured subset of intelligence. said there
were multiple intelligence. - ANSWER- What is the history of the expert intelligence
definitions?
includes
1) body kinetics
2) musical intelligence
3) intrapersonal intelligence
4) interpersonal intelligence
5) naturalistic intelligence - ANSWER- What is Gardners theory of multiple intelligence?
intelligence is a multifacet capacity that includes that ability too
1) acquire knowledge
2) reason logically and plan effectively
3) grape and visualise concepts
4) find right words and thoughts
5) cope and adjust to novel situations - ANSWER- What would we consider a general
defintion of intelligence?
,it is a complex concept by which hereditary and environment are presumed to interact
with and influence development of intelligence. - ANSWER- what is interactionalism?
to devise appropriate measures, evaluate measures, and ensure assessment covers
construct sufficiently. - ANSWER- Why is it important to know the structure of
intelligence?
It was invented by Pearson in 1901 and further developed by spearman in 1904.
it is a family of statistical techniques used to examine correlations among variables,
items and or tests.
the two types include
1) exploratory factor analysis = used when want to know the structure
2) confirmatory factor analysis = used when want to confirm structure with a different
sample.
this played a powerful role in shaping 20th-century development and understanding of
the structure of intelligence. - ANSWER- What is factor analysis and what are the two
types?
it identifies underlying dimensions in data. for example, how many personality factors
are there, or does intelligence consist of one factor or more?
it investigates correlations among variables and groups them together to create factors.
for example item 1 (sociability), item 2 (outgoing), and item 3 (optimism) correlate with
each other. therefore they are factor 1 (Extraversion) etc. - ANSWER- What is
exploratory factor analysis?
1st order factors = individual items
2nd order factors = correlation groups of individual items.
3rd order factors = correlation between 2nd order factors. - ANSWER- How do 1st
order, 2nd order and third order factors differ?
Look at what items are correlated together (e.g. being talkative and being social). If they
are correlated they will be a factor (e.g. extraversion). - ANSWER- How can we work
out how many factor there are in factor analysis based off of a correlation table?
Fluid intelligence (Gc)
- is the ability to solve new problems, use logic in new situations, and identify patterns
- largely non-verbal and culture reduced form of mental efficiency.
- It stays the same in cognitively healthy people.
Crystallised intelligence (Gc)
, - the ability to use learned knowledge and experience.
- Highly culturally dependent and used for tasks that require a learned response.
- peaks in 30s. - ANSWER- What are fluid and crystallised intelligence?
The extension included an extended number of second tier factors but still no g.
the additional factors included
1) Quantitative knowledge
2) reading and writing
3) short term memory
4) visual processing
5) auditory processing
6) long term retrieval
7) processing speed
8) correct decision speed - ANSWER- What was the extension of catell and horns
model?
1) spearman 2 factor theory: performance determined by general intelligence (g) and
specific intelligence (s). many tests heavily g.
2) Thurston's PMA theory: said there was no g but several factors (7 validated). found
inter-relations between them and thus later accepted g's existent. his theory was not
used.
3) Vernon: provided a link between Thurston and spearman. proposed heretical group
structure. that included overarching factor (like g), 2 grouping factors and minor factors,
and specific factors (like spearman s)
4) cattle and horn: Used Factor analysis. said there were no g or group factors. there
was fluid (GF) and crystallised intelligence (GC) . said G was reflected in GF and GC
but not a third-order factor.
5) Caroll: reviewed factor analytic research and revised the catell and horn model with
the main difference being g was the overarching factor. called this 3 strata model of cog
ability. - ANSWER- What is the history of the structure of intelligence?
1) integrates all 3 models.
2) has 10 broad stratum and over 70 narrows.
3) each broad stratum subsumes 2 or more narrow abilities.
some broad factors include
1) domain-specific knowledge
2) psycho-motor speed
3) olfactory abilities
4) tactile abilities
5) kinaesthetic abilities
