“The current study shows that the subjective experience of difficulty depends on multiple cues that are indicative of performance. It is shown that response conflict, reaction time, and response repetition influence subjective difficulty judgments. Trials that were congruent, fast or required the same response as the previous trial were more frequently rated as easy compared to trials that were incongruent, slow or had alternating responses. Moreover, the relative contribution of these cues can be changed by means of training: training participants to rely more on congruency or reaction time for their subjective difficulty judgment increased the influence of this cue on their judgment” (Desender et al., in press)
