============================= Notes & Documentation: Category learning with imperfect feedback   Ekaterina Stepanova Cognitive Science Laboratory Simon Fraser University Notes created: Apr 24 2013 Last updated: Apr 24 2013 =============================   The two .zip files here contain raw data from a categorization experiment. SSHRC_IFGazeLvl-2013-03-28.csv.zip is a .csv file containing raw gaze information from Tobii x120 eye trackers. sshrc_if.zip contains three separate .csv files: one at the experiment level, one at the trial level and one at the fixation level. All four tables share a participant ID for indexing between levels. 1. Experiment level table; column information Subject: the subject number SubjectCondition: Either 1, 6, 7 or 8: 100% feedback, 87.5% correct feedback, 75% or 62.5% correct feedback Location1Feature: The image pasted to location 1. Will have the relevance Location1Relevance. Location2Feature: The image pasted to location 2. Location3Feature: The image pasted to location 3. Location1Relevance: The category value of the feature that appears in location 1 for that participant. Location2Relevance: The category value of the feature that appears in location 2. Location3Relevance: The category value of the feature in location 3. CatQButton: joystick button for category Q CatRButton: joystick button for category R CatSButton: joystick button for category S CatTButton: joystick button for category T ParticipantEstimate: Estimate of feedback accuracy rowID: unique row index CP: When the participant reached the learning criterion EQP: Exposure point: how many times a category was presented before the participant learned category Q. ERP: Exposure point: how many times a category was presented before the participant learned category R. EPS: Exposure point: how many times a category was presented before the participant learned category S. EPT: Exposure point: how many times a category was presented before the participant learned category T. GazeDropper: If 0, <30% of trials are flagged for bad gaze (see triallvl in sshrc_if.zip) LPQ: Learning point: number of trials before the participant learned category Q. LPR: Learning point: number of trials before the participant learned category R. LPS: Learning point: number of trials before the participant learned category S. LPT: Learning point: number of trials before the participant learned category T. Phase2GazeAcceptable: Has a value of 1 if >75% of trials exceed 70% gaze collected. 2. Trial level table; column information Subject: the subject number TrialID: trial number StartTime: start of the trial Feature1Value: 0 or1 Feature2Value: 0 or 1 Feature3Value: 0 or 1 Correct Response: the category the stimulus belongs to Response: participants' responses TrialAccuracy: 1 = correct FeedbackResponse: provided feedback FeedbackAccuracy: accuracy of the feedback GazeCollected: The proportion of gaze data for that trial that was correctly collected FixationRT: Reaction time during the fixation cross presentation. StimulusRT: How long the participant looks at the stimulus before (s)he presses a button indicate that (s)he's ready to respond FeedbackRT: How long the participant looks at the feedback screen (includes stimulus and indicator of accuracy) Fixation/Stimulus/Response Onset: Based on internal equipment time: when the fixation/stimulus/response phase of the trial began. ResponseCongruency: If the participants' response matches the feedback response. RowID: Unique index badPhase2: Exclude data for bad gaze while the stimulus is on screen badPhase4: Exclude data for bad gaze while the feedback is on screen pFixIrrelPh2: 1 if the participant fixated irrelevant information during the trial while the stimulus was on screen. 3. Fixation level table; column information Start: a time point out of the eye tracker, indicates the time that the gaze point is collected Duration: The length of the fixation in milliseconds Subject: the subject number TrialID: Trial number TrialPhase: Phase 1 is the fixation cross presentation, phase 2 is when the stimulus is on screen, and phase 4 is the feedback presentation. RowID: Unique index X: the x-coordinate of the fixation Y: the y-coordinate of the fixation Location: The area of interest in which the fixation falls FuncRelevance: The functional relevance of the area in which the fixation falls. 4. Gaze level table; column information Subject: the subject number Session: 1; will always be a value of 1. ID: unique row index TETTime: A time point from the eye tracker marking when the gaze point is collected RTTime: A time point from the experiment software indicating when the gaze point is collected CursorX: the x-coordinate for the gaze point CursorY: the y-coordinate for the gaze point TimestampSec/MicroSec: Additional time markers XGazePosLeftEye/RightEye: x coordinate of the position of the gaze from each eye YGazePosLeftEye/RightEye: y coordinate of the position of the gaze from each eye XCameraPosLeftEye/RightEye: location of the left eye relative to the eye tracking camera YCameraPosLeftEye/RightEye: location of the right eye relative to the eye tracking camera DiameterPupilLeft/RightEye: diameter of a pupil of each eye DistanceLeftEye/RightEye: distance from an eye-tracker to each of the eyes ValidityLeftEye/RightEye: A Tobii marker of whether or not the eye tracker is able to collect gaze during that time point TrialID: trial number TrialPhase: Phase 1 is the fixation cross presentation, 2 is the stimulus on screen, 4 is feedback
