Lecture 17 - Can Intelligence Change Flashcards

(12 cards)

1
Q

Why do we want to increase IQ?

A
  • Access to predictive validity
  • Educational achievement: IQ levels at age 5 predicted different levels of intelligence in literacy and numeracy
  • School outcomes: longitudinal, intelligence predicted standardised exam results.
  • Life outcomes: experience in school predicts life outcomes: lit& num predicts socio-economic/earnings level at 42. Diff of 1Iq point = 4% economic growth

What does IQ affect?

A
  • Wages
  • Changes in social class
  • Physical health
  • Smoking beh
  • Life sat
  • Diagnosis of depression/mental health
  • Diseases inc cardio
  • Education endurance
  • Mortality rates

Q

Can IQ be improved and how?

A
  • Socio-economic status will change IQ scores:
  • Grouping students by ability in school can improve intelligence scores
  • Flynn effect suggests IQ increases over generations via generation via access to internet
  • IQ can fall due to neurodegeneration, acquired brain injury, absence from school (6 lower IQ points), lower activity levels, and diet (multi-vitamins & iodine)
  • Intelligence is not stable over our lifespan, and therefore can be manipulated

Q

Do brain training games work?

A
  • Most commercial brain training games (neuro racer) do not work to improve IQ
  • Some particular video games involves multi-tasking = improved ppts performance, working memory, and sustained attention
  • Results did not generalise to general intelligence

Q

How did other researchers try to improve working memory to improve IQ?

A
  • Dual N Block task
  • Ended up improving working memory and fluid intelligence (problem solving) Not general levels of IQ - no cross-domain transfer

Q

Details of a pilot study to improve intelligence:

A
  • Changes in env = changes in IQ
  • Intervention informed by relational frame theory may improve IQ
  • Prev work in area found that skill in relational responding is related to improved performance in IQ tests
  • Studies have been correlational

Q

Method of pilot study

A
  • 8 children from 8-12 years took WISC (baseline measure of intelligence) and then allocated to condtion: active/control
  • Given to stimulus-X training
  • Wisc test again = divergence occurs
  • Exp group trained further relational abilites and given an IQ test 9 mo after

Q

Results of pilot study

A
  • Both groups had above average IQ
  • After stim training = relatively sim
  • Diverge massively after relational training

Q

What was the second study?

A
  • Gave 8 11-12 year old children their test over a 9 mo period
  • Ppts full IQ score rose by 13 points
  • 3 subscales of WISC improved but Working Mem did not improve

Q

What was a recent study that supported the one above?

A
  • Relational responding as a theory of intelligence and improving it
  • Achieved cross-domain effects, suggesting relational abilities (can be trained) can affect IQ

Q

What was the critical analysis?

A
  • People had vested interest as they wrote the book on the theory that was then published
  • Pilot study = small N = low power
  • Control groups inadequate = control group had nothing after group 1 = 1 practical issues as people do not want to be a control, they want to improve their IQ
  • Outside learning opportunities are not controlled for = important if env affects IQ
  • Is SMART feasible? Can it be done without a researcher present.
  • Long-term effects = return to baseline eventually.
