Different Forms of Plasticity Interact in Adult Humans

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
