Four school children of different ages and grades responded vocally at three levels of stimulus uncertainty (Hs) to visually presented Arabic numerals. S-R compatibility was greatest for the oldest child and least for the youngest. Reaction time (RT) was influenced by both Hs and S-R compatibility; the effect of Hs on RT was greatest where S-R compatibility was lowest.
