intelligence part 2 Flashcards
(16 cards)
cimmon IQ tests and neurodivergence…
some adjustments can be done e.g. colourblind versions however tasks often applied without adjustments so those who are neurodivergent may be disadvantaged.
neurodivergent individuals are at risk of…
being wrongly regarded as having little cognitive potential.
brain volume and IQ
2015 a meta analysis found a positive analysis however there was a publication bias- favoured studies with positive correlations and those with non significance were ignored.
a study into postmortem brains of danish men…
found that there was no correlation between IQ and number of brain cells- weak correlation between IQ and brain weight.
what do brain differences mean…
changes in white mattter as a result fo learning a new skill- taxi drivers of london had increased grey matter in their hippocampus.
haier and benbow found that…
male participants there were significant correlations between maths and glucose in temporal lobes but female had no correlation.
what is the neutral efficiency theory
some people have more efficient brains so the more efficient use of cortex- so more intelligent you are they use brain areas less.
efficiacy of white matter organisation…
predictive of intelligence in females and intellignece on grey matter related to volume in males.
finn et al- fMRI explored functional connectivity patterns…
connectivity appeared to be able to predict levels of fluid intelligence.
what is connectoyping
distinct pattern of brain activity that characterises the way each other peoples mind works.
sex differences in white metter- the taxi study
white matter: learning a new skill, increased white matter in london taxi drivers- Woollett & maguire (2010)- training moderated this
what is the neural efficiency theory?
higher efficient brans use their cortex more efficienty andt therefore are more intelligence becuase they use less brain areas
what was the sex difference in grey matter
male: increase in fronto parietal associated with intelligence whereas this was not found in women.
what was the sex difference in white matter
male had no association but in females white matter predicted intelligence
what is meant by white matter efficinecy in relation to intelligence
positive correlation with IQ.
what are the sex differences in brain size
males is 10.8% larger than females.
