Age-related differences in the automatic processing of single letters: implications for selective attention.

Older adults exhibit diminished ability to inhibit the processing of visual stimuli that are supposed to be ignored. The extent to which age-related changes in early visual processing contribute to impairments in selective attention remains to be determined. Here, 103 adults, 18-85 years of age, completed a color selective attention task in which they were asked to attend to a specified color a...

Age-related Differences in Processing Speed in Preschool Children

The aim of this study was to assess whether age-related differences in reaction time can be explained satisfactorily in terms of a global age-related differences in processing speed alone. We investigated the age-related differences in simple, discrimination and choice reaction time in 4to 6-year-old children and young adults using approach proposed by Madden et al. and Ridderinkhoff & van der ...

Age-related differences in brain activation during emotional face processing.

Advancing age is associated with significant declines on neurobehavioral tasks that demand substantial mental effort. Functional imaging studies of mental abilities indicate that older adults faced with cognitive challenges tend to activate more regions, particularly frontal, than their younger counterparts, and that this recruitment of additional regions may reflect an attempt to compensate fo...

Age-Related Differences in Spatial Frequency Processing during Scene Categorization

Visual analysis of real-life scenes starts with the parallel extraction of different visual elementary features at different spatial frequencies. The global shape of the scene is mainly contained in low spatial frequencies (LSF), and the edges and borders of objects are mainly contained in high spatial frequencies (HSF). The present fMRI study investigates the effect of age on the spatial frequ...
