Age differences in cued vigilance task performance were examined. Cues were
presented central location at stimulus onset asynchronies (SOAs) of 300ms. Target
and non-target were the squares of 3.3 cm and 3.0 cm respectively. The participant’s
task was to pay attention to the cue and then to make a speeded decision about
the presence or absence of the target by pressing the response key. A 2 (Age
Group: Young and Old) x 3 (Cue validity: valid, invalid and neutral) x 3 (Time period:
3 Blocks of 10 min. each) analysis of variance (ANOVA) with repeated measure
on last two factor was used. Results revealed that performance was facilitated
under valid cue condition for both young and old adults. It further indicated qualitative
difference on vigilance performances in young and old adults. Overall detection
was similar for both the groups but young adults were faster in detecting the targets
in comparison to their older counterparts
