Resources

exe8stim.tbz (44 KB) - Stimulus image files.
exe8data.csv (59 KB) - Trial-level raw data. Column headings are as follows:
- subj: Participant number (unique within EXE8)
- block: Experiment block
- trial: Trial number (resets between blocks)
- stim: The to-be-classified stimulus presented, numbers refer to stimulus file names in exe8stim.tbz
- resp: Participant's classification response (A = category A, B = category B)
- rt: Participant's reaction time for classification response (in milliseconds)
exe8classic.csv (1 KB) - Subject-level raw data for the classic "combined" analysis used in match-to-standard tasks. This is where each block is classified as UD, OS, or Other, on the basis of both the objective sort produced, and the participant's description of that sort (see paper for details). Participants' descriptions were not archived for this study. ** This file also contains the OSPAN score for each participant ***.
exe8analysis.R (3 KB) - R script for the analyses of Wills et al. (2013, QJEP).
