This data supplements the study of:
Witzel, C., & Gegenfurtner, K. R. (2015). Categorical facilitation with equally discriminable colors. Journal of Vision, 15(8), 22. doi:10.1167/15.8.22, http://jov.arvojournals.org/article.aspx?articleid=2381517
The Excell-file provides the data shown in Figure 4 of the above article, which shows the main results. The first sheet (trained) provides the data for the first, experienced group of participants, the second sheet (naive) the data for the naive, untrained group of participants.
Rows refer to the 20 stimulus pairs.
sti_ctg = category membership of each colour in a pair.
sti_type = type of colour pair: 1 = centre pair, 2 = boundary, 3 & 4 = transitional pairs
sti_azi = Hue (azimuth) in DKL-space
rt = response times, one column for each observer
er = error rates, one column for each observer
