A uniform interface to common response time preprocessing decisions
that precede analysing aggregated response times or fitting an evidence
accumulation model. Screening rules from different preprocessing routines
-- absolute cutoffs, standard deviation and median absolute deviation
criteria, recursive moving criteria, and model-based mixture flagging --
all return the same per-trial object, so that consequences of a
preprocessing choice can be compared rather than assumed. The package also
provides aggregation into EZ-diffusion summary statistics, diagnostics
reporting what each rule removed and where rules disagree. Finally,
generators for response time data with contaminants of known type are
provided, so that a chosen pipeline can be tested against ground truth.
Screening criteria follow Van Selst and Jolicoeur (1994)
