Lr. Gottlob et Dj. Madden, TIME-COURSE OF ALLOCATION OF VISUAL-ATTENTION AFTER EQUATING FOR SENSORY DIFFERENCES - AN AGE-RELATED PERSPECTIVE, Psychology and aging, 13(1), 1998, pp. 138-149
Adult age differences in the time course of the allocation of visual a
ttention were investigated, in 2 experiments that both included the sa
me 10 younger adults (M = 22 years) and 10 older adults (M = 68 years)
. In Experiment 1, older adults accumulated information about target i
dentity at a slower rate than younger adults, as represented by the ri
se in accuracy as a function of target duration. To equate performance
in a baseline condition in a spatial-cuing paradigm (Experiment 2), t
arget duration was set for each observer on the basis of the data in E
xperiment 1. Performance for the 2 age groups was comparable, both in
the baseline condition and in the time course of attention, as indexed
by the function relating accuracy to cue-target onset asynchrony. The
authors conclude that, in this spatial-cuing paradigm, an age-related
change is evident in sensory processing but not in attentional alloca
tion.
