Within an information processing framework, age-related declines in speeded responding are attributed to one or more stages of processing. It was the purpose of this experiment to demonstrate the potential reversibility of this decline in at least one processing stage, response selection. Two groups of elderly participants (57 to 83 years) were pretested on a two-choice reaction time (RT) task under two levels of spatial stimulus-response (S-R) compatibility, a task demand shown to affect response selection. Following the pretest, one group participated in 7 weeks of videogame play, whereas a second group did not. All participants were posttested on the same two-choice RT task. The results of the analysis of covariance revealed that those elderly individuals who played videogames were faster than the control participants under both levels of S-R compatibility. The effect of videogame play, however, was greater for low compatibility. These results are taken as support for a potential to improve response selection through videogame play.
