We included thus all trials for testing the classifier (disregarding the trial type, correctness, retrieval confidence, or run).
Feedback was provided after each practice trial, either on correctness when an incorrect response was given or on both correctness and speed in the case of a correct response.
Neurophysiological processes on correct and erroneous trials were analyzed in a repeated-measures ANOVA using the within-subject factor "correctness" (correct vs. error) and the between-subject factor group (controls, de novo PD).
The degree of correlation between the performance in the discrimination task and subjective visibility was assessed with the non-parametric Kendall τ, which tested the trial-by-trial relationship between the correctness of the discrimination response (a binary variable) and the PA score [24].
PS was the Program Section Leader Phase III (having overall responsibility for the conduct of the trial and overseeing the correctness of the outputs), NPP was the study Clinical Trial Leader and was involved in the conduct of the trial, and both were involved in the design of the trial.
Since there are now two sources (an auditory word and a visual word), there is no longer a notion of correctness, but trials will fall into three groups: those on which the auditory word is reported, those on which the visual word is reported, and those on which a different word (distracter) is reported.
Obvious political correctness run amok.
Since day 1 contained only small amounts of retrieval trials (8 trials per condition, per run), we included all retrieval trials in the analysis (irrespective of correctness or retrieval confidence).
We included all retrieval trials in this analysis (irrespective of correctness or retrieval confidence), since day 1 contained a substantially lower amount of retrieval trials (8 trials per condition, per run).
