    Abstract

    Active lifestyles might protect cognitive abilities; however, studies
    rarely consider the reverse causal direction. Activity-cognition
    associations might reflect stable intelligence differences rather than a
    protective effect of activity. The Lothian Birth Cohort 1936 (n = 1091)
    completed cognitive tests aged 70, having taken an intelligence test
    aged 11. Activity (assessed by participation in 15 activities that
    produced a socio-intellectual activity factor, and by physical activity)
    was positively associated with cognition (r = .08 to .32, p = .05).
    When age-11 IQ and adult social class were controlled, only physical
    activity remained significantly associated with general cognitive
    ability and processing speed. (PsycINFO Database Record (c) 2012 APA,
