Compatibility effects in a two-hand cranking task

Abstract

48 SS WERE RUN ON A 2-HAND CRANKING TASK IN 4 INDEPENDENT GROUPS WITH DIFFERENT CONTROL-DISPLAY LINKAGE. WITHIN-GROUP CONDITIONS INCLUDED 3 STIMULUS CODES AND 4 RESPONSE COMBINATIONS. TOTAL ADJUSTMENT TIME AND RESPONSE LATENCIES FOR EACH HAND SERVED AS RESPONSE MEASURES. RESULTS FOR TOTAL ADJUSTMENT TIME SHOWED SIGNIFICANT STIMULUS CODE AND PRACTICE EFFECTS, BUT NO DIFFERENCES FOR RESPONSE COMBINATIONS OR FOR THE STIMULUS CODE-RESPONSE COMBINATION INTERACTION. LATENCY DATA REVEALED A PRONOUNCED STIMULUS CODE EFFECT CONSISTENT WITH THAT FOR TOTAL ADJUSTMENT TIME AND DEMONSTRATED THAT CONTROL OF THE LATERAL DIMENSION YIELDED SHORTER LATENCIES THAN THE IN-OUT DIMENSION, REGARDLESS OF THE HAND INVOLVED. THUS, THERE WAS EVIDENCE OF STIMULUS-RESPONSE (S-R) BUT NOT R-R COMPATIBILITY EFFECTS. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
