week 12

Question 1

What is the coefficent of determination?

Answer 1

A coefficent of determination is what you get if you square a correlation to estimate the % of shared variance. A pearsons r of 1 is 100%, so like, if you were doing how much oppenness impacts intelligence, 100% means it’s a perfect fit, so oppeness predicts intelligence perfectly and theres no other factors.

Question 2

What is the overlap between intelligence and personality?

Answer 2

In a meta analysis, associations between FFM and intelligence found only openness correlated substantially with intelligence.

Question 3

What is the connection between intelligence and academic performance?

Answer 3

A study examining 70k british school students over 5 years, tested intelligence at 11, and then 16 years. Found a strong association between their intelligence and academic achivement, which was also replicated in another meta analysis (interestingly, effect stronger at higher levels).

Question 4

personality and academic performance.

Answer 4

Conscientiousness was a substantial predictor in self report studies at all grade levels, as was oppenness, though effect size was weaker, particularly at higher levels (eg tertiary education).

Question 4

personality and academic performance.

Answer 4

Conscientiousness was a substantial predictor in self report studies at all grade levels, as was oppenness, though effect size was weaker, particularly at higher levels (eg tertiary education).

Question 5

personality and academic performance OTHER measures.

Answer 5

interestingly, when you don’t do self report (so, other people report your personality, such as friends, teachers etc), the effect is much stronger for personality traits and achievement, particularly for openness and conscientiousness.

Question 6

Right, the ‘third pillar idea’ of intellectual engagement and academic achievement.

Answer 6

In one small meta analysis, some dumb bitch thought TIE predicted academic performance as much as conscientiousness. However, Chris said only one scale of intellectual curiosity predicted variance above intelligence and conscientiousness, not others. some people reckon its the same thing as Gf and interest. essentially, intellectual curiosity doesn’t mean shit xx

Question 7

IQ and job performance.

Answer 7

IQ is a good predictor of Job performance, as are C and integrity tests.

Question 8

IQ and job complexity

Answer 8

IQ tends to be a better predictor of performance in more complex jobs

Question 9

what about the idea that highly gifted people have no advantages (IQ over 120).

Answer 9

liza minelli, lies.
Lubinski assessed the intellectual accomplishments of those within top 1% as kids, and went back decades later. the top quarter of the 1% outperformed everyone substantially

Question 10

C and job performance and complexity.

Answer 10

C related to job performance more than any other, BUT, only in less complex jobs. reckon thats bc high flying jobs need new thinking and problem solving.

Question 11

Personality and death.

Answer 11

Joketa meta-analysed FFM traits as predictors for death, only low C was associated with increased risk of death. more to do with ppl with low levels being shit at healthcare etc, rather than those with high levels being superheros.

Question 12

cognitive epidemiology

Answer 12

term coined by deary to describe research into IQ as a predictor of health. There is a substantial negative relationship between IQ and death; childhood IQ is a substantial predictor of death in adulthood. 1SD higher IQ cnofers reduced risk of death across many causes.

Question 13

What is the body insults hypothesis for cognitive epidemiology?

Answer 13

Childhood IQ is a measure of insults (damage) to the body that have already occurred by that age.

Question 14

intelligence and liberalism

Answer 14

liberals smarter fuck yes bitch x

Question 15

humour and intelligence

Answer 15

humour and intelligence are correlated substantially, r.3 Gc and 4 Gf. Evidence indicates some overlap between humour and mating success.

Question 16

Grip Strength and IQ

Answer 16

grip strength has a positive association with IQ. who fucking knows.

Question 17

Assortive mating

Answer 17

people of similar intelligence levels often go together, particularly crystallised. also height and education.

Question 18

iq and short sightedness

Answer 18

higher IQ associated with higher levels of myopia. causal relationship is not clear.

Question 19

iq and short sightedness

Answer 19

higher IQ associated with higher levels of myopia. causal relationship is not clear.

Question 20

brain training; N back.

Answer 20

Dual n-back is a task of working memory that requires remembering visual and auditory information several steps back in a sequence. thought to work because working memory is key to intellectual function, but not true. you might get better at memorising lists lol. this is representative of TRANSFER ( or lack of). that training brain in one thing usually means it doesn’t work for everything else.

Question 21

What is transfer?

Answer 21

Near transfer involves gains that apply to more similar tasks, whereas far transfer applies to less similar tasks (and more general abilities)
Working memory training in general has shown no evidence of far transfer

Question 22

Aerobic excercise.

Answer 22

Stern et al found aerobic groups improved in IQ over 12 weeks more than control, though works better for older participants

Question 23

iq and education

Answer 23

Meta-analysis indicates estimates that more education increases IQ (1–5 points/year)
•“Education appears to be be the most consistent, robust, and durable method yet to be identified for raising intelligence” (Ritchie & Tucker-Drob, 2018, p. 1358)
