A negative trend was observed in the relation between estimated intelligence quotient (IQ) scores and age ( r = –0.33, P = 0.063), indicating that in this sample IQ scores decreased with age.
However, a marginally significant relationship was observed between the probability of a hit and age [ F (1,30) = 3.43, P = 0.074], indicating that performance decreased proportionally with age.
