Double stimulation with varying response requirements
Abstract
Conducted 3 experiments with a total of 60 female undergraduates to test the unitary assumption of B. H. Kantowitz's 1974 response conflict model, which states that the same mechanism is responsible for both reaction time effects (RT1 and RT2) in double stimulation. Response conditions called for response (R1 and/or R2) to first stimuli (S1) and second stimuli (S2), to only S1, or to only S2. In Exp I, S2-R2 was a subset of the S1-R1 set such that S1-R1 was characterized by 2 bits of uncertainty while S2-R2 had 1 bit. Similar interactions between interstimulus interval (ISI) and response conditions were obtained for both RT1 and RT2. In Exp II, S2-R2 was not a subset of S1-R1. Both interactions obtained in Exp I disappeared. In Exp III, similar interactions between S1-R1 information and ISI were obtained for both RT1 and RT2. These similar patterns of interaction and additivity for both RT1 and RT2 support the unitary assumption. (26 ref)Preview Only.
