Abstract Details

2017, Master of Arts, Ohio State University, Psychology.
Conflict in the Stroop task is measured by both response time and accuracy. The amount of conflict differs depending on the response modality, verbal vs. manual. We applied a model for multichoice decision making (and confidence), the RTCON2 model (Ratcliff & Starns, 2013) to the data from four experiments, 2 variants with 2-choice manual responses, one with 4-choice manual response and vocal response, and a 4-choice touch screen experiment. Changes in the rate of information accumulation captured conflict effects for the manual response and touch screen versions, but not for the vocal response version. Adding an extra non-decision time parameter allowed RTCON2 to accurately capture the data patterns in the vocal response version. However in order to fully understand conflict in the vocal response Stroop, a model of conflict processing in the vocal system must be developed.
