Object-based attentional selection and aging

Article Abstract:

Two studies were undertaken to investigate potential age-related differences in object-based attentional selection, based on critical manipulation of objects. Space-based models of selective attention predict no differences, although object-based attentional selection models predict better performance when both target properties appear on a single object. The results were consistent with object-based attentional selection models, and both young and old adults exhibited similar performance effects.

Attentional flexibility and aging: you don't need to be 20 years of age to split the beam

Article Abstract:

Young and old adults performed equally well in tests that measured their ability to pay attention to two objects at the same time. The test is based on the theory that adults can pay attention to two objects given that the two objects are contained within a unified area within the visual field. Subjects were asked to compare two objects that were separated by a distractor image, proving the validity of object-based models of visual processing.

The implications of cortical recruitment and brain morphology for individual differences in inhibitory function in aging humans

Article Abstract:

Individual differences in cortical recruitment, brain morphology and inhibitory task performance are assessed. Morphological analysis revealed that frontal white matter tracts differed as a function of performance in older adults, suggesting that hemispheric connectivity might impact both patterns of recruitment and cognitive performance.
