Changes in cerebral lateralization in aging. 1984

L K Obler, and S Woodward, and M L Albert

To determine whether there is increasing left hemispheric lateralization for language with age and whether the right hemisphere is selectively impaired with advanced age, we tested 96 right-handed people aged 25-80 yr on verbal and non-verbal matching tasks presented tachistoscopically. Task difficulties was equalized by adjusting exposure durations. Exposure duration, error laterality and response latency laterality were analyzed. Typical field effects as well as age-related slowing and sex by task interactions were observed. However, no systematic age-related changes in lateralization were apparent.
