# Perceptual coupling induces co-rotation and speeds up alternations in adjacent bi-stable structure-from-motion objects Data and analysis for the __"Perceptual coupling induces co-rotation and speeds up alternations in adjacent bi-stable structure-from-motion objects"__ manuscript currently submitted to _Journal of Vision_. ## Analysis The complete analysis, including all figures and statistical comparisons, can be found in Jupyter notebooks. ## Data files format ### Experiment 1 Each row corresponds to a single event that occurred during a block. Session-specific columns: * `Observer` observer ID, matches the file name * `SessionID` timestamp for the session start Block-specific columns: * `Block` block index * `Shape` shape used for the block, either `sphere-0500` or `cross-0500` * `Gap` spatial layout condition for the block: * `-0.15` the _overlap_ condition * `0` the _touching_ condition * `0.15` the _gap_ condition * `Unambiguious` ambiguity condition for the block * `Direction` direction of rotation for the biased object, if applicable. `-1` correspond to the rotation to the left, whereas `1` to the right. Event-specific columns: * `Percept` experimental event (`start` or `stop`, resplectively the start and end of the block) or the pressed button (`up`, `left`, `down`, `right`). `unclear` means that no key was pressed at that time. Buttons correspond to the following perceptual states: * `left` for both objects the direction of rotation was to the left (i.e., object’s front surface moved to the left) * `right` both objects rotated to the right. * `down` the left object rotated to the left, whereas the right object rotated to the right. * `up` the left object rotated to the right and the right object rotated to the left. ### Experiment 2 The original data is stored in Matlab `.mat` files. Same raw data is also stored in a single CSV-file `Experiment 2.csv` with following columns: * `ObserverID` unique observer ID * `DisplayType` spatial layout of the two spheres: * `H` horizontally arranged * `V` Vertically arranged. * `RotationAxis` axis of rotation: * `X` horizontal' * `Y` vertical * `Background` background type: * `0` uniform * `1` textured * `Distance` distance between the spheres in the units of the radius. * `Percept` reported percept: * `-2` unclear * `-1` counter-rotation * `1` co-rotation * `Time` time relative the start of the block in seconds ## License All data (and associated content) is licensed under the [CC-By Attribution 4.0 International License](https://creativecommons.org/licenses/by/4.0/).
