Abstract : A four choice reaction-time task using color and symbol dimensions was varied in terms of type of stimulus presentation and S-R compatibility. Six groups of 20 Ss each performed six different task versions. Responding with hands only in four groups proved significantly easier than hand-foot responding in two other groups. The group receiving a singular dimension of colors performed significantly better than a group receiving only symbols. Both of these groups demonstrated greater efficiency than two groups required to filter 'noise' or irrelevant dimensions. Distributions of scores increased considerably about group means with increasing informational load and decreasing S-R compatibility. The utility of the choice reaction task for discriminating individual skill potentials in various information-handling situations was affirmed. (Author)
