Question 1

meta-cognition

Answer 1

ability to:
reflect on
and evaluate
our own thought processes

Question 2

intelligence contains

Answer 2

intellectual self-awareness
ability to improve independently through self-evaluation

Question 3

IQ is

mean is, SD is

relative means

Answer 3

a standardised statistical score
- your performance relative to others

mean of 100, SD = 15

relative = how individual’s performance compare to that of others

Question 3

self-rating accuracy of intelligence

Answer 3

65% believe they are better than average
55 think below average

correlation between self-assessed and objectively measured is .30

Question 4

Z scores

+ calculation

Answer 4

mean of 0
SD of 1

Z-score of 1 is 1 SD above the mean

if IQ score is on average (100), then z-score is 0
z-score of -0.91 x 15) -100 = 86.35

Question 5

test scores are compared with:

Answer 5

others in the same age group
there are 13 age bands

Question 6

intelligence across age

matrix reasoning

Answer 6

20 yr old doing 19 questions
same IQ as
80 year old doing 9.5 questions

absolute levels of intelligence differ

Question 7

peaks of

verbal comprehension
processing speed
perceptual reasoning

Answer 7

vc = increases at middle age then decline
ps= peak 16.5 age
pr = mid 20s
all decline with age

Question 8

intelligence is decreasing

Answer 8

whole brain volume from 18-35 = 85%
from 75+ = 75%

age-related atrophy

Question 9

intelligence a predictor of:

Answer 9

academic performance
- cognitive abilities for learning
job performance

Question 10

genius vs giftedness

Answer 10

1. Describe individuals with exceptional talents or achievement
2. exceptional intellectual, creative+ arts, high performance in standardised assessments

Question 11

intelligence - income, longevity

Answer 11

higher earnings - higher intelligence
lower risk of accident by 7% - with each 1 point increase in intelligence

Question 12

how many people are gifted in aus?

Answer 12

2% of population is moderately
25 australians have profound level

Question 13

idiot savant is

Answer 13

developmental disabilities but exceptional skills
now outdated + offensive

Question 14

twice-exceptional + its rarity

Answer 14

intellectually gifted + learning disability
- is rare because of ‘positive manifold’

in 1 million person simulation == 1 person had it = rare

Question 15

positive manifold?

Answer 15

consistent findings –> cognitive abilities positively correlated across individuals
- one good cognitive test = good in other tests

Question 16

higher order structure of intelligence

2 structures

Answer 16

verbal intelligence

performance

Question 17

verbal intelligence subtests

Answer 17

digit span
information
vocabulary
arithmetic, similarities
- high correlation of info + vocab .81

Question 18

performance intelligence subtests

Answer 18

picture
block design
digit symbol
- correlation 0.63 block and object assembly

Question 19

cross categories

Answer 19

0.56 of arithmetic and block design

Question 20

structure of intelligence

Answer 20

general intelligence at the top
P + V
cognitive abilities below

Question 21

Cattell-horn-Carroll model
3 stratum theory

Answer 21

Stratum III = general intelligence - overall cognitive ability
Stratum II = broad abilities like fluid + crystallised intelligence, memory, processing speed
Stratum I = narrow abilities eg verbal fluency

Question 22

brain volume and intelligence
correlation

Answer 22

r=.4
more cortical surface area - brain has gyro + sulky

Question 23

myopia

Answer 23

heritable 85%
intelligence heritablility 47%
positive correlation r=.57

Question 24

intelligence heritability

increases with age - Wilson effect

Answer 24

47%
nearly half differences in intell due to genetic factors
(rest is environ - education, upbringing)

Question 25

cognitive abilities between genetic related individuals…?

Answer 25

wilson effect - increases with age
thus, genetic + environ

Question 26

gender differences - mental rotation

Answer 26

= capacity to observe visual object + manipulate in mind
males better
highly dependent on the object (eg pram, truck)

Question 27

fagan + holland

racial differences + intelligence

Answer 27

‘black and white’ learn new word, venter
same exposure to word and training
–> no significant difference in knowledge of the word
–> learning efficiency - indicate intelligence

GROUP DIFFERENCE NO USE, NEED INDIVIDUAL

Question 31

flynn effect

Answer 31

rising IQ score 3-5 points per decade in developED countries
- digit span not meaningfully modified over the years

Question 32

education +intelligence

+ expertise

Answer 32

formal education increase intelligence
norway experiment 1.5IQ for 2 year more education

digit span 6-8
with training, increase to 79
practicing does NOT change

Question 33

far-transfer

Answer 33

improvement on tasks that are dissimilar to one trained
eg. sudoku for problem solving skills

Question 34

video games +intelligence

Answer 34

correlation is there
due to processing speed

Question 35

what is intelligence??

Answer 35

maximal capacity to achieve a novel goal successful using perceptual-cognitive processes

Question 36

3 parts of intelligence definition

Answer 36

1. maximal capacity - solve novel problems, not personality related
2. novelty - solve ones that not previously encountered
3. peceptual cognitive functions - like attention, video and auditory perception

Question 37

AI

Answer 37

maximal capacity successfully achieve novel goal through computational algorithms

LLMs have training, datasets
