Abstract 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 difficulty 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.
