Description

The data files are all in csv format, organized in columns for each variable and rows for each instance.
The column names denote the variables, explained below.

---BINOCULAR RIVALRY DATA--- 

The experiment consisted of reporting the perceived orientation of a Gabor patch. Participants observed two 
different Gabor patches (counter-clockwise -45° or clockwise 45°) projected separately on their two eyes 
through a mirror stereoscope. They reported the perceived orientation by pressing the left (counter-clockwise), right (clockwise), or down (mixed) arrow keys.

-FILES-
data_BR    : main experimental cohort
data_BR_vc : visual control condition
data_BR_wm : working memory control condition

-COLUMN NAMES-
grating                : perceived grating orientation (1 counter-clockwise 45°, 2 clockwise 45°, 3 mixed)
trial                : trial number (2 total in a block)
subtrial        : sub-trial number (4 total in a block)
position        : position of the counter-clockwise grating (1 left, 2 right)
perceiving_eye        : the eye that is dominating perception at that instance (1 left, 2 right)
phase_duration        : phase duration in seconds of the perception instance 
ID                : participant ID
block                : block number (8 total in a session)
deprived_eye        : code for the deprived eye (1 left, 2 right)
logPhaseDur        : log10 transformed phase duration
session             : session code (1 simple, 0 combined, 2 control)

---MOTOR SEQUENCE LEARNING DATA---

The experiment consisted of tapping four fingers (middle finger excluded) on a response pad, following a 
sequence displayed on the monitor. The numbers on the sequence correspond to fingers (1 thumb, 2 index, 
3 ring, 4 little). Participants practiced two of the sequences for 14 blocks (test sequences) and two 
others for only 1 block (control sequences) in the initial training. Each hand was trained separately. A 
retest of two blocks for each of the sequences was done 45 minutes after the initial training per hand.

-FILES-
data_MSL  : main experimental cohort

-COLUMN NAMES-
part        : part number (4 in total: 2 test, 2 control)
block        : block number (up to 14 for test sequences)
trial        : trial number (5 in each block)
repetition    : repetition number (i.e. completion of the sequence, 3 in each trial) 
RT        : reaction time in seconds
accuracy    : whether the sequence was correct (i.e. no finger tap error) (1 correct, 0 incorrect)
ID        : participant ID
sequence_num    : sequence number (1: control, 2 test)
used_hand    : is this the dominant hand (1 yes, 0 no)
first_hand    : which is the first-trained hand (1 dominant, 0 non-dominant)
hand        : which hand is currently used (1 left 2 right)
run        : run number (1 initial training, 2 retest after 45 minutes)
logRT        : log10 transformed reaction time
session        : session code (1 simple, 0 combined)

---WORKING MEMORY DATA---

The experiment consisted of reporting whether a probe letter belonged to a previously seen set. The set of letters (3, 5, or 7 elements) was flashed (? sec) one by one (ISI ?) and after a 3 second pause a probe was flashed. Participants indicated if the probe belonged to the set by pressing arrow keys (left arrow no, right arrow yes). They received auditory feedback on their accuracy.

-FILES-
data_WM  : working memory control condition

-COLUMN NAMES-
response  : participant's response (1 yes, 0 no)
accuracy  : accuracy (1 correct, 0 incorrect)
block      : block number (3 in each run)
trial      : trial number (30 total in each block)
length      : set length (3,5 or 7)
set      : the set of letters shown
RT      : reaction time in seconds
probe      : probe letter
ID      : participant ID
run      : run number (1-4)
logRT      : log10 transformed reaction time
