IQ

Spearhead

G factor- factor analysis

Factor analysis

Statistical procedure

Identifies a cluster of related items on a test

Where are you now and before - is there improvement or did u digress

Spatial numeric reasoning

Spatial ability

Verbal comprehension

Word fluency

Perceptual speed

Numerical ability

Inductive reasoning

Memory

Howard Gardner

Savant syndrome

Multiple intelligences beyond g factor

Musical

Mathematical

Linguistic

Naturalist

Interpersonal

Intrapersonal

Spatial

Kinesthesis abilities

Intelligence

Mental ability to learn from our experiences

Aptitude test

What is the predictability of how well you’re going to do in the future Eg college entrance exams

Achievement test

Tests you’re achievement for Eg Ap psych test at the end of the year

WAIS

Testing is test for just adults

Wisc) just for children

Tests made by wlechler

Characteristics of a normal bell shaped curve Regarding it

Mean= 100 average intelligence

100-115 =-15 1 standard deviation above the mean

85-100 =1 standard deviation below

68% is 1 standard deviation above and below the mean

95% is 2 standard deviations above and below the mean

99% 3 standard deviations bone and below the mean

Reliability

How a test has consistent results:

Split half

Alternative form

Test retest

Split half reliability

Do even and then do odd

The scores should be similar between the 2 tests

Test retest reliability

Giving the same test a little bit later and seeing if there are some similarities and consistency

Alternative form reliability

Giving another form of the test

Eg: mcq vs frq

Might not really be good for reliability because you would do a lot less on a fill in he blank

Content validity

Extent to how the test samples the behaviors of interest

Measuring what you’re trying to measure

Eg: driving tests where you’re in the parking lot isn’t really content validity

Predictive validity

Ability to be able to predict how well you’ll do in the future

Eg an aptitude test in knowing how well you’ll do in a career

Crystallized intelligence

Accumulated knowledge

It grows like a crystal

Increases with time

Because you’re experiences life and wisdom type stuff

Fluid Intelligence

White water rafting

Our ability to reason with speed, tends to decrease with age

Our abnikuity to learn something quickly

Cross sectional research

Compares people of different ages at the same point in time

Representing all people of different ages causes it to be cross sectional because its all at the same time

Lot cheaper than longitudinal research - advantage in comparison

Longitudinal research

People might quit

Other factors that can contribute to skewing the results

People lie

People die

People move

Expensive

Iq tests scores over time

Yeah there’s consistency that levels out over time

The earliest that might give more accurate iq test predictability is >4

Longitudinal study in 1932 iq test accuracy

Trying to target and see which children need a university and which go to working class

Asks 70 years later for another iq test 542 survivors from ww2

Look at data and come up with a reason why

Doesn’t have generalizability - not a lot of diversity

Lower iq didnt live as long because they had les money and education and healthcare per example of nature vs nurture

Down syndrome/trisome

Copy of chromosome 21

The chromosome gives the physical features

Has difficulty with intellect

Moodier/difficult with social interactions

Organs dont work as well - dont have long lifetime

Giftedness

Savant

Someone who is very gifted in a particular subject but can’t really do common things

Polygenetics

Involving many genes

Identifies how smart we are

G factor

We dont use it any more because its too general and it can be anything

Practical intelligence

Everyday activities

How to change a tire / getting dressed and what to wear, making choices and common sense

Kinesthesic

Gardner talked about how people are effortless at is

Gymnastics

Synchronized swimmers

Intrapersonal

Evaluate yourself and why you do things

Eg; knowing your sick before you have any symptoms ( same feeling or look before you get sick)

Able to know why im mad

Interpersonal is you with others

Interpersonal

Recognizing and understanding why somebody else is having a certain emotion

Eg: autism tend to look at nose and not able to tell what somebody is having a certain emotion

Formula for it

Mental/chronological x 100

Has to be above 100 to be correct

If its under 100 that means you did something wrong

Stereotype threat

They think that they’re being judged based on a stereotype and do kind of worse y

Who came up with the 8 intelligence types

Charles spearman

Who first developed an intelligence test to establish the idea of mental age

Binet

Who created the original intelligence test

Binet

What is the most widely accepted theory of intelligence today

Sternbergs triarchic theory of intelligence
