Can suggestion obviate reading? Supplementing primary Stroop evidence with exploratory negative priming analyses.
Using the Stroop paradigm, we have previously shown that a specific suggestion can remove or reduce involuntary conflict and alter information processing in highly suggestible individuals (HSIs). In the present study, we carefully matched less suggestible individuals (LSIs) to HSIs on a number of factors. We hypothesized that suggestion would influence HSIs more than LSIs and reduce the Stroop effect in the former group. As well, we conducted secondary post hoc analyses to examine negative priming (NP) - the apparent disruption of the response to a previously-ignored item. Our present findings indicate that suggestion reduces Stroop effects in HSIs. Secondary analyses show that LSIs had an NP effect at baseline (i.e., without suggestion) and that suggestion influenced the NP condition. Thus, at least in this experimental context, suggestion seems to dampen a deeply-engrained and largely automatic process - reading - by wielding a larger influence on HSIs relative to comparable LSIs.
