Increasing control improves further control, but it does not enhance memory for the targets in a face-word Stroop task.

Recent research on the dynamics between attentional and memory processes have outlined the idea that applying control in a conflicting situation directly leads to enhanced episodic memory of the processed information. However, in spite of a small subset of studies supporting this claim, the majority of the evidence in the field seems to support the opposite pattern. In this study, we used a face-word Stroop task to enforce different control modes either from trial to trial or in an item-specific manner. Both manipulations of congruency proved to be effective in making participants' responses to conflicting stimuli more efficient over time by applying a trial-specific control mode. However, these manipulations had no impact on memory performance on a surprise recognition memory test. To our knowledge, this is the first attempt at measuring the memory consequences of the application of specific control modes at the trial level. The results reported here call for caution and possibly reconceptualization of the relationship between cognitive control and memory.
