Theories of intelligence
There’s no single widely accepted theory of intelligence
Spearman two-factor theory
- derived from factor analysis
- a general intellectual Factor ( g)
- numerous specific factors (s)
– performance on cognitive test depends on general intellectual ability and one or more specific factors unique to the test/task
General intellectual factor
Spearman’s two-factor theory
- mental energy
Numerous specific factors
Spearman’s two-factor theory
- different engines for which the energy is expressed
Horn and Cattel’s theory of intelligence
- there’s two primary cognitive abilities
- crystallized intelligence. (Gc)
-Fluid Intelligence (Gf)
Crystallized intelligence (Gc)
Horn and Cattel’s
- dependent on education and culture
- important for performance on tests and tasks that require the application of acquired knowledge or skills
Ex. Vocabulary and test a factual knowledge
Fluid intelligence (Gf)
Horn & Cattell
- innate ability
- doesn’t depend on prior learning or experience
- important on tests/task that involve reasoning, solving novel/abtrack, problems, drawing inferences, and perceiving relationships and similarities
Crystallized and fluid intelligence
Horn&Cattell
+ Not completely independent
- correlation efficients .40 through .50
Age-related decline of fluid and crystallized intelligence
Horn & Cattell
+ Fluid intelligence: peaks between 30 to 40 and then declines, related to degeneration in certain areas of the brain, including the hippocampus and PFC, declines in working memory and processing speed
+ Crystallized intelligence: may not peak until 60-70

Carroll’s Stratum theory
- Three strata (levels) of intelligence
Third: general intelligence, underlies all other cognitive abilities
Second: eight broad cognitive abilities, crystallized intelligence, fluid intelligence, general memory and learning, and processing speed
First: multiple specific abilities linked to one of the broad abilities
- sequential reasoning, qualitative reasoning, and speed of learning contribute to fluid intelligence
Cattell-Horn-Carroll’s theory of cognitive abilities (CHC)
- combined Horn & Cattel and Carol’s theories
- intelligence consists of 16 broad cognitive abilities and over 80 narrow cognitive abilities each linked to one of the broad abilities
- serves as a framework for several tests including Kaufman and Stanford-Binet
PASS theory of intelligence
- 4 cognitive functions that interact with person’s knowledge
- derived from research on cognitive function of different brain structures
Planning
Attention
Simultaneous processing
Successive processing
- intelligence test focus on analytical and neglect. Creative and practical intelligences which contribute to occupational and academic success
- framework for Kaufman children’s battery and cognitive assessment system
Planning
PASS THEORY OF INTELLIGENCE
- IDENTIFYING/ SELECTING AND EVALUATING SOLUTIONS TO PROBLEMS
Attention
PASS Theory of intelligence
- focusing on certain stimuli while inhibiting responses to competing stimuli
Simultaneous processing
PASS Theory theory of intelligence
- the integrating different stimuli into a single coherent whole
Successive processing
PASS Theory of intelligence
- organizing specific stimuli into a a specific sequential order
Sternberg’s triarchal Theory
- successful intelligence is the ability to accomplish personally meaning goals in life within the context of one’s culture
- and intelligence consists of three factors: analytical intelligence, creative intelligence, and practical intelligence
Analytical intelligence
Sternberg’s: triarchial Theory
- aka componential intelligence
- comparable to general (g) intelligence
- knowledge acquisition and information processing skills used to analyze, evaluate, compare and contrast information
Creative intelligence
Sternberg’s: triarchal Theory
- AKA experiential intelligence
- ability to apply knowledge and information processing skills to novel problems and unfamiliar situations
Practical intelligence
Sternberg’s: triarchal Theory
AKA contextual intelligence
- ability to apply knowledge and information, process and skills to everyday tasks and situations

SB5: STANFORD BINET INTELLIGENCE TEST 5TH EDITION
- measure of cognitive assessments for measure of cognitive assessments for 2 to 85+
- based on the general mental ability model
- incorporates five cognitive factors from CHC Theory
- each factor has nonverbal and verbal domains
Fluid reasoning
Sb5
- information on ability to solve nonverbal/verbal problems with inducive and deductive reasoning
Nonverbal: object series, and matrices
Verbal: early reasoning, verbal absurdities, and verbal analogies
Knowledge
Sb5
- acquired information/generalinfo learned in school etc
- nonverbal: procedural knowledge and picture absurdities
Verbal: vocabulary
Qualitative reasoning
Sb5
- information on math and problem solving
Nonverbal: non-verbal qualitative reasoning
Verbal: verbal qualitative reasoning
Visual spatial processing
Sb5
- information on ability to see patterns and relationships
- respond to whole front parts
- non-verbal: form board and form patterns
Verbal: position and direction
Working memory
Sb5
- ability to store, sort, and transform information to short-term memory
nonverbal: delayed response and block span
Reverbal: memory for sentences and last word
Administration of sb5
- tailored to the cognitive ability of the examinee
- starts with administration of two routing. Subtest: object series/matrices and vocabulary to determine where to start off administration of the other subtest
- administration of other subtests begin at a level slightly below the examine’s ability level as determined by the routing symptoms
- examiner then determines the examine’s basal level for each subtest, which is the highest point at which the examinee answers all of the questions correctly. For two consecutive age levels, testing continues until the examiner reaches his or her ceiling level, which is the point at which the examinee misses 75% of the questions at two consecutive age levels
Scoring of the sb5
+ mean of 10 and a standard deviation of 3
- combined to obtain four composite scores with a mean of 100 and a standard deviation of 15
- full scale IQ(scores from all subtests), Factor indexes (scores from the nonverbal and verbal subtest for each factor), 2domains (All scores from the non-verbal and the verbal subtests) , and abbreviated battery (scores on the routing subtest and provides A quick estimate of an examinee fluid and crystallized cognitive abilities)
Wais IV
- measure of cognitive ability for 16 to 90 years of age
- provides a full scale IQ test and scores on indices and subtests
Verbal comprehension
WAIS-IV
- ability to retrieve verbal information from short-term memory and reason with it
Core: vocabulary, similarities, information.
Supplemental: comprehension
Perceptual reasoning
WAIS-IV
- information on nonverbal reasoning and problem solving
Core: block design matrix reasoning and visual puzzles.
Supplemental: figure weights and picture completion
Working memory
WAIS-IV
- information on initial registration , retention, and mental manipulation of information in short-term memory
Core: digit span and arithmetic
Supplemental: letter number sequencing
Processing speed
WAIS-IV
- info on verbal, motor, and visual motor processing speed
Core: symbol search & coding
Supplemental: cancellation
Test administration of WAIS-IV
- administration of each subtest begins at start point indicated on record form
- when a examinee gets two consecutive a zeros on the first two items administered, the reverse rules used which involves administering earlier items in reverse order until the examinee obtains a perfect score on two consecutive items
Discontinuance rule on each subtest varies and is either a designated number of consecutive items that receive scores of zero or a designated period of time
Scoring of the WAIS
- scores have a mean of 10 and a standard deviation of 3
- combined to obtain a full scale IQ and index scores which have a mean of 100 and the standard deviation of 15
General ability index can be derived from scores on the verbal comprehension and perception reasoning indexes
Scoring of the WAIS
- scores have a mean of 10 and a standard deviation of 3
- combined to obtain a full scale IQ and index scores which have a mean of 100 and the standard deviation of 15
General ability index can be derived from scores on the verbal comprehension and perception reasoning indexes
Interpretation of the wais
- multi-step process that involves considering the examinee’s full-scale IQ, index and subtest scores to identify strengths and weaknesses
-GaI: useful when an examiner wants a summary score for an examine that minimizes the impact of working memory and processing speed
