Table 2. Features used in decoding analyses of native language groups.

Analysis	Feature Vector	Description
Single-Trial	64×540	Concatenated single-trial ERPs for standard and deviant
		trials in all three measurement conditions
Single-Trial (Combined)	64×540	Combined single-trial predictions (70) per participant
Grand-Average A	64×540	Concatenated individual grand-average ERPs for standard
		and deviant trials in all three measurement conditions
Grand-Average B	64×180	Concatenated individual grand-average ERPs for 63 ms
		VOT deviant and 41 ms VOT deviant
Behavioral	1×7	Mean individual behavioral responses to the
		stimulus continuum used in the original study

Feature vectors are described in terms of [channels]×[time points], with the exception of the behavioral analysis, which included mean individual responses to each of the 7 stimuli in the continuum used in the original study by Brandmeyer et al.
