Color constancy supports cross-illumination color selection

Individual
observer's data: AAB
The
tables below provide individual observer data for the color selection
and the color adjustment part of the study, as tab delimited text.
For each part we provide two data files: one for the
illumination-constant condition, the other for the illumination-changed
conditons
(bluish and yellowish illuminant-changed conditions combined).
Color selection task
Selection data for
each condition: Illuminant-constant,
Illuminant-changed.
Data tables for both
conditions follow the same format:
Column 1: Condition code (NC for
illuminant-constant; CY and CB for yellowish and bluish
illuminant-change, respectively).
Column 2: Block number
Column 3: Trial type (denoted as a unique integer; refers to a
specific combination of target, competitor pair and illumination
condition)
Column 4: Target (1 for "Gray", 2 for "Rose"; 3 for "Teal" and 4 for "Green")
Column 5: First competitor in the
competitor pair on a given trial (Convention for illumination-constant
condition: 1= C-2,
2 = C-1; 3 =
T; 4 = C+1; 5 = C+2; For illumination-changed condition 1= T,
2 = C1;
3 = C2;
4 = C3; 5 = R; 6 = C5; See Figure 2).
Column 6: Second competitor in the
competitor pair on a given trial (same convention as in Column 5).
Column 7: Competitor chosen by the
subject on a given trial (1 = the first competitor in a pair, 2 = the
second competitor in a pair).
Column
8: Reaction time in seconds (from the trial onset until the subject
made a choice).
Column 9: Session order number
(tracked separately for illuminant-constant and illuminant-changed
conditons).

showing subject's choices and inferred matches (follows
the same conventions as Figure 3A):
Illuminant-constant, Illuminant-changed (yellowish),
Illuminant-changed (bluish).

Different
illumination condition is plotted in each row: top -
illuminant-constant (NC); middle - illuminant-changed (CY); bottom -
illuminant-changed (CB).
Each
target is plotted in a different column (marked as T1 to T4). Each
subplot follows the same conventions as Figure S2 (supplement).

Figure follows
the same conventions as Figure A4 in the Appendix.
