Abstract

We measured behavioural performance and fMRI activity whilst old and young adults performed a temporal

segmentation task (‘preview search’). Being able to select parts of the visual world to be attended or ignored

is a critical visual skill. Both old and young adults were able to improve their performance on a difficult search

task when some of the distracter items were presented earlier than the remainder. Comparisons of brain

activity and functional connectivity, however, suggested that the underlying mechanisms are quite different

for the two age groups. Older adults' activation patterns do not correspond to those predicted by simple

increased involvement of frontal regions reflecting higher demand with age but seem to suggest that changes

in brain activation patterns propagate throughout the cortex
