How do we meassure intelligence ?
Via the Multidimensional Aptitude Batter test
How does the multidimensional test work ?
it test for
- Vocbulary (Find a rlated word to theg given word)
- Spatial (matching two shapes
- Arithemtic (math)
- Picture arrangment (conclude the comic in the way that it makes the most sense
Which ability does each component of the - Multidimensional Aptitude Batter describe ?
- Vocabulary = verbal ability
- Arithmetic = quantitative ability
- Spatial = spatial orienatation
- Picture arrangment = Social interpretation
Who is the first person who tested mental ability ?
- Alfred binet
What was spearman main research question ?
- Is there a single major dimension of mental ability, or whether there are instead several independent varieties of mental ability ?
What did sperman concluded regarding his research question ?
- That there is a general intelligenece
What is the g factor ?
- correlation between two task
What is the principell of the indiffernce of the indicator ?
- the content of the task does not matter regarding high g loading or low g loading
Why is the g factor not a common thing anymore ?
- because the g factor could not explain the relation among various mental abilities -> thurstone
What is a high g loading task ? And explain it
- Check the relationship of a given statment and copy it relationship to the new part -> definition
- eduction of relations and correlates -> task
What are the primary factors regarding thurstone ?
- Verbal fluency
- Verbal comprehension
- Numerical facility (= ability to work quickly with numbers)
- Spatial visualisation (= ability to imagine shapes from different perspectives)
- Memory
- Perceptual speed
- Reasoning
What is the thurstone opinion regarding teh g factors ?
- several factors are needed to explain mental ability ?
What are some critics regarding primary factors ?
- All factors had something in common
- IQ test only focused on verbal factors
What is the G + group factor ?
- You have mulitple factors which all come together at the general mental ability lvl !
What is gilford opinion regarding mental ability ?
- that there are more then 180 intelligent factors
What is the critic on Gilford opinion ?
- Way to many factors
- not enough emparical evidence !
What are the developmental changes regarding mental ability ?
- mental ability increase rapidly through childhood till late adolesence and then decrease during old age
Which study should we use and why should we use it to explore mental ability ?
- longitudinal stidy
- because u aviod the cohort effect
What are the factors influencing mental abilities ?
- Brain size (certain regions
- Reaction time (the shorter the better)
- inspection time (how long does a timuli has to present to be caught by the brain)
Name the other correlaters regarding mental ability:
- Nerve conduction speed (nerve system and brain transmmit pulses)
- Averaged evoked potentials (brain waves in response to stimuli)
- Brain glucose metabolism – rate at which brain uses glucose
- Womb Environment Influences (nutrients, toxins, and hormones)
- lower lvl of Vitamin B12 = mental ability
- brith order
What is so special about birth order ?
- First born higher IQ
- Steaching second chidl
- undivided attention
- > All social
What is the relation regarding evolution and mental abilities ?
- Mutation increase or decrease mental abilities
- Depending on the coast and benefit ratio
What is the relationship regarding academic achievments and mental ability ?
- there is an important link
- 0.6 correlation
- Maybe the test was to similar to IQ test
