Resources
- exe8stim.tbz (44 KB) - Stimulus image files (from EXE8).
- exe9data.csv (83 KB) - Trial-level raw data. Column headings are as follows:
- cond: Experimental condition
- subj: Participant number (unique within EXE9)
- 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.
- exe9analysis.R (4 KB) - R script for the analyses of Wills et al. (2013, QJEP).

match-to-standards task under
