The current study investigated the extent to which challenging the informational demands of the cognitive system impact reaction time in a linear, systematic fashion. Specifically, the study examined the effects of simultaneously challenging all three stages of the information processing. A 3 (Response Selection) x 2 (Stimulus Identification) x 2 (Response Programming) ANOVA with repeated measures was used to analyze mean reaction time data. The results indicated that, to a point, information processing increases in a linear, systematic fashion. However, when the system is substantially stressed, speed of processing is negatively impacted. This results in an over-additive increase in reaction time. Movement time analysis in complex response conditions indicated a similar increase at this level of informational load. One explanation for this finding is that the cognitive system has a finite information capacity, after which efficient processing of information is hindered.
