usedData.Rdata

- for all lines that are used for analysis (allData(:,1)==1) a field in an R dataframe is created, which contains the following fields (for details, see description of matlab file above):

obsNum: the ID of the observer (1-24)

condNum: the ID of the condition (1-6)

imgNum: the ID of the image (48 unique numbers between 1 and 135)

fixDur: fixation duration

LUM, LCG, ED, ECC: luminance, contrast, edge density and eccentricity at fixation

empMapFromSearch, empMapFromPref, empMapFromMem, empMapFromJoint: values of empirical maps generated from data of experiment 1 (search, preference, memorization task as well as combination of the latter two) at fixation

empMapFromC1 through empMapFromC6: value of empirical map generated from condition 1 through 6 at fixated location

empMapFromC1loo through empMapFromC6loo -  value of empirical map generated from condition 1 through 6 at fixated location leaving out the current observer

x,y - coordinates of fixation
