reading on intelligence part 3

Question 1

edcuation

Answer 1

Associations between IQ gains and GDP have been linked to educational improvements (Rindermann, 2008)

Tuijnman 1991= improvements in educational systems in industrialized societies as potential causes for rising IQ scores

Question 2

GDP

Answer 2

Positive associations of GDP with IQ gains have been observed in several studies and countries (for an overview, see Lynn & Vanhanen, 2002)
In particular, the substantial effect of GDP on crystallized IQ may be linked to educational effects. It has been proposed that investments in better education lead to economic growth and vice versa, thus leading to a positive feedback loop of economic prosperity, education, and intelligence (Rindermann, 2008). Of note, it has been shown more recently that increases in GDP may be better described as a function of education rather than the other way round (Rindermann, 2012), which in turn would reverse the causality assumption of the regression model applied by us

Question 3

technology

Answer 3

It has been suggested that the reported gains may reflect effects of increased exposure to modern appliances that incidentally train visual analytical abilities (Neisser, 1997). A more stimulating visual environment (e.g., owing to more exposure to computers, television, or video games) would thus act as a facilitating factor for abilities required to successfully master intelligence tasks.
