Individual
observer's data: LDO (Experiment 2B)
For each set, the
tables below provide the CIELAB and xyY values for the inferred matches
derived via our analysis in Experiment 2A.
For each target and condition, these values correspond to the
competitor sample that was included in the customized competiotor set
for this subject.
Inferred matches (based on finalized analysis) (Set A, Set B)
Preliminary inferred matches (presented in the experiment) (Set A, Set B)
Data tables follow this format:
Column 1: Condition code (NC
for
illuminant-constant; CY for yellowish illuminant-change, CB for bluish
illuminant-change).
Column 2: Target number (T1: "Gray" in Set A, "Corn" in Set B; T2: "Rose" in Set A, "Skin" in Set B; T3: "Teal" in Set A, "Lettuce" in Set B; T4: "Green" in Set A, "Bark" in Set B).
Columns 3-5: xyY values of the inferred match.
Columns 6-8: CIELAB values of the inferred match.
The
tables below provide individual observer data for the blocks task, as
tab delimited text.
For each set, we provide one data file for all conditions
(illumination-constant and illuminant-changed combined).
Block selection data (Set A, Set B)
Data tables follow
this format:
Column 1: Condition code (NC for
illuminant-constant; CY for yellowish illuminant-change, CB for bluish
illuminant-change).
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, SetA: "Gray", Set B: "Corn": 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; 6 = Subject's inferred match).
For illumination-changed condition 1= T,
2 = C1;
3 = C2;
4 = C3; 5 = R; 6 = C5; 7 = Subject's inferred match).
Column 5: Target 1, SetA: "Gray", Set B: "Corn": second competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 6: Target 1, SetA: "Gray", Set B: "Corn": competitor chosen by the
subject on a given trial (1 = the first competitor in a pair, 2 = the
second competitor in a pair).
Column 7: Target 2, SetA: "Rose", Set B: "Skin": first
competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 8: Target 2, SetA: "Rose", Set B: "Skin": second competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 9: Target 2, SetA: "Rose", Set B: "Skin": competitor chosen by the
subject on a given trial (1 = the first competitor in a pair, 2 = the
second competitor in a pair).
Column 10: Target 3, SetA: "Teal", Set B: "Lettuce": first
competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 11: Target 3, SetA: "Teal", Set B: "Lettuce": second competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 12: Target 3, SetA: "Teal", Set B: "Lettuce": competitor chosen by the
subject on a given trial (1 = the first competitor in a pair, 2 = the
second competitor in a pair).
Column 13: Target 4, SetA: "Green", Set B: "Bark": first
competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 14: Target
4, SetA: "Green", Set B: "Bark":
second competitor in the
competitor pair on a given trial (same convention as in Column 4).
Column 15: Target
4, SetA: "Green", Set B: "Bark":
competitor chosen by the
subject on a given trial (1 = the first competitor in a pair, 2 = the
second competitor in a pair).
Column
16: Reaction time in seconds (from the trial onset until the subject
made a choice).
Column 17: Session order number.
Note: NaN value for competitor chosen (in Columns 6, 9, 12 or 15)
indicates that no block from the source was assigned to this target
block (and the corresponding block in the workspace remained black)
or that the block that was assigned was not one of the two competitors
for this target (and was thus excluded from the analysis).
