Y. Lacouture et D. Lacerte, STIMULUS MODALITY AND STIMULUS-RESPONSE COMPATIBILITY IN ABSOLUTE IDENTIFICATION, Canadian journal of experimental psychology, 51(2), 1997, pp. 165-170
Accuracy and response time (RT) were measured in the absolute identifi
cation (Al) of ten unidi-mensional perfectly pairwise discriminable st
imuli. One group of 20 subjects performed a visual AI task involving l
ine segments of variable length. A second group of 20 subjects partici
pated in an auditory task with the stimuli composed of pure tones of v
ariable intensity. Subjects performed the task under two conditions: a
spatially compatible and a spatially incompatible stimulus-response m
apping. Results showed greater accuracy for the visual modality and lo
nger RT for the incompatible mapping. The experimental factors did not
substantially alter the bowing observed when performance was plotted
according to the ordinal position of the stimuli. The data do not supp
ort the hypothesis that the bow effect is attributable to motor progra
mming or motor adjustment stages.
