Data for "A Double Dissociation between Savings and Long-Term Memory in Motor Learning" For analysis code and any updates, please visit https://github.com/AlkisMH/Savings_vs_Long_Term_Memory For any questions, please contact Alkis Hadjiosif (alkis [at] seas [dot] harvard [dot] edu; ahadjiosif [at] gmail [dot] com) These .mat files contain data collected for Experiments 1-4 and S1, used to reproduce Figures 1-6 and S1 in the paper. Data for each experiment are in the form of a Matlab structure, with each field consisting of a [Num_trials x Num_participants] matrix. The fields are: TN: Trial Number VF: Whether visual feedback was given during the trial (1: online visual feedback; 2: no visual feedback) Rotation: The visuomotor rotation imposed on each trial (in degrees). CCW is positive, CW is negative. Wait: Whether, right before the trial, a wait time was imposed (1) or not (0). Trials immediately following breaks are indicated by (2). Instruction: Whether an instruction was given for the trial (1) or not (0). Only present in Experiment 3. Note that Experiment 3 includes: -> Two specific instruction trials during learning and and two during relearning, before and after the 1-minute wait ("Move your hand to the center of the target","Move your hand to the far end of the target") -> Six random instruction trials before initial learning and six before relearning ("Move your hand to the left/right/near/far end of the target"), to familiarize participants with the instruction process ITI: Time (in seconds) since the last trial (regardless of direction). theta_target: Target direction (in degrees) relative to the 12 o'clock position. Only included for Experiment 4: target is always at 12 o'clock for Experiments 1-3. theta: = reaching direction relative to theta_target, measured 150ms into the movement. Note that this is flipped based on the rotation sign so that adaptation towards the imposed visuomotor rotation is always positive. theta_end: = reaching direction relative to theta_target, measured at the end of movement. Only included for Experiment 4: it is to be used for the no visual feedback blocks in Experiment 4. Note for Experiment 4: the last two blocks (last 114 trials) were done on day 2.
