Earlier, we saw different brain regions involved in object, background and binding processing. Now, we see if these regions might be engaged differently in older adults. Older adults typically show poorer episodic memory but relatively preserved item processing that does not require episodic or contextual access. Might this be due to a reduced engagement of binding processes in the MTL of older adults?
We found that not only is MTL reduced, but older adults seemed to not process the entire visual stimuli in the same way as young adults. In particular, older adults seem to process only background components of the pictures while somewhat treating the objects less attentively. Abstract: Age-related changes in object processing and contextual binding revealed using fMR adaptation.
So we know that at least part of the changes in aging might be related to the partial processing of the entire picture rather than the entire central item and context. Next, we turn to consider what are some of the factors that might lead to these changes with age.
