Important people /tests Flashcards
Sir Francis Galton
-craniometrist
- assessed people on size of head and performance of physical tasks E.g. eyesight, strength of grip, colour vision, hearing and hand preference
- believed in higher order that underpins physical properties and metal aptitude
- UK 1884 he created his inteligence test
Jean-Martin Charcot
-Founder of modern neurology
Alfred Binet
-disolusioned with Craniometry especially due to confirmatory bias
-Moved to psychometrics (pshychological measurments of indefinable things)
-1905 published Binet-Simon test published - devised to identify children with special educational needs ergo lagging behind peers.
- Binet left legacy that intelligence should be assessed in relation the population of which the test is intended (children aged 6 for children aged 6 etc).
- believed intelligence was not fixed and could be developed
- BElieved intelligence testing should only be used as a rough diagnostic tool
- Against the use of IQ
Binet-Simon test (Standford-Binet Test)
54 tasks
40 mins
HAd to follow commands, measure differences in length, define abstract words, memorise spoken numbers, name objects
Ranging from easy to difficult
Results were compared to the chronological age norms and the result was said to be the mental age.
Translated to English by Henry Goddard and amended by Spearman. Renamed Standford-Binnet test is now gold standard.
Most recent version of the test eas published in 2003
Charles Spearman and g
British Psychologist
Supported that assesment based on a varity of different tasks could derive an overall measurement of intelligence as there was correlation between performances in the different groups proved there was an underpinning factor
He coined the factor ‘general intelligence’ known as g.
Evidence for conclusion not strong
g lies at the core of IQ and assumptions of IQ testing
Willam Stern and IQ formula (the first version)
German psyhcologist
wanted to encapsulate intelligenc into a singular number to allow easy comparison.
This number became IQ
The IQ formula became mental age ÷ chronlogical age (actuall age) = IQ
Terman IQ test formula (for children)
proposed the ration of the multiplied by 100 to round up the IQ score
Terman’s formula
IQ = mental age ÷ chronological age x 100
This formula is derived only for tests developed for children
W.A.I.S - The Wechsler Adult Intelligence Scale
-Developed to measure adult intelligence in 1939
-WAIS - IV is the latest edition published in 2008
-strongly copywrighted
- Consists of 10 core subjects grouped into 4 components
1. Verbal Comprehension - general verbal skills
2. Perceptual Reasoning - measure non-verbal reasoning
3. Working Memory - how much info can a persons menmory hold to complete a task
4. Processing Speed - speed and accuracy of processing visual information
Test produces and overall IQ and 4 index scores one for each componant.
WAIS stucture aknowledges that Human intelligence is more complex than the idea of g (general intelligence).
Each section has 14- 33 questions in order of difficulty
MAKINTOSH - New Research 2011
Has shown that there is closed links to parential interest in education, play and ‘push’ or not their children and IQ test results
DUCKWORTH et AL - 2011 New research on IQ performance
Proved that materieal incentives imporved performance on IQ tests by 10 points.
Possibly performance on intelligence tests is influenced by motivation.
What are the core 3 criteria of a learning disability?
- show significant impairment of intellectual functioning
- show significant impairment of the ability to adapt to their environment or interact with people around them.
- these impairments occured before adulthood.
What IQ threshold is a learning diability?
70
(Although Webb and Witaker 2012 indicate that this is only acurate within plus or minus 4 points as people with learning disabilites are likely to be emotionally strongly effected by testing environment)
What did Web and Whitaker say about the current learning disability diagnositic process?
It is based op the ‘passive acceptance of a flawed definition and unreliable measurement’
-Agreed with by judges
(pg 100)
What is the suggested revised definition of a learning disability?
A person can be regarded as having a learning disability if they are juged to be in need of community care or educational services due to a failure to cope with intellectial demands of their environment and are
- suffering significant distress
-unable to taje care of themselves or their dependants
-unable to protect themselves against significant harm or exploitation
Peter Salovey and John D Mayer’s definition of Emotional Intelligence (EQ) - 1990
A form of social intelligence that involes the ability to monitor one’s own and others’ feelings and emotions, to discriminate among them and use this information to guide one’s thinking and action
