The effect of stimulus onset asynchrony between different response cues on reasoning in a base rate task

Recent theories of dual processing propose the existence of multiple Type 1 processes which cue responses during reasoning. If these responses do not point towards the same answer then that conflict may be detected. If the conflict is detected, Type 2 processing is initiated to resolve it. This study is concerned with the timeline and relative strength of different Type 1 processes in a modified base rate task. The task can cue congruent (stereotype and probability point towards the same answer) or incongruent responses. We varied the SOA (stimulus onset asynchrony) time between the stereotype inducing and base rate information. The study was a 2 (congruence) × 3 (SOA: 200, 800, 1400ms) experimental design. The analysis of the total data set showed a significant congruence effect regardless of SOA for both response times and confidence. Additionally, an analysis of stereotypical and base rate responses was conducted for each level of SOA. Results showed a marginal response type by SOA interaction effect. Response times decreased for the base rate and increased for stereotypical responses as SOA increased. The same effect was not found for confidence ratings. The results imply responses cued by the stereotype information decreased in strength as SOA increased. This effect may lead to a conclusion that Type 1 process strength decays over time.
