Auditory Perceptual Learning using Mixed-Training Regimens

All data from the PLoS ONE paper: <em>Acquisition versus Consolidation of Auditory Perceptual Learning using Mixed-Training Regimens</em>. AMD and AMR raw trial data were log-transformed (log₁₀ Hz). Data from each adaptive track (block of 30 or 60 trials, from testing and training blocks, respectively) were fitted with a logistic psychometric function using the Psignifit toolbox, and the thresholds were estimated as the 79.4% correct point on this function. Missing data points (i.e. due to experimental error) assigned -999 value. Data were exlcuded on a case-by-case basis (see filters): Tracks where the optimization procedure did not adequately fit the data (i.e. when the fitted slope was negative or when the fitted threshold value was outside the measured range) were discarded. Further outlying data were excluded based on individuals whose pre-test thresholds were &gt; 2 standard deviations difference from the population mean or post-test thresholds were &gt; 2 standard deviations from the group mean on a condition-by-condition basis.
