DR-AVXmod-02_ReproducibilityDemo

This data set contains source files for two participants together with a code to run all analyses for the purpose of demonstrating reproducibility of the findings. The data were collected from 28 neurotypical, young adult humans who were presented with a stream of visual stimuli shown at the screen centre. The visual stimuli comprised gratings of different, randomly selected orientations at a fixed spatial frequency. Occasionally, the presented grating had a higher spatial frequency - the target grating - and participants counted the number of targets per trial (between 0 and 9). Concurrently with the visual stream, a series of pure sounds were played from a flat speaker mounted at the screen centre. For the most part, the sounds repeated engendering an expectation about the next sound. At unpredictable intervals, the expected, standard sounds, was replaced by a different, oddball sound, violating the expectation. Thereafter, the novel sound repeated for a while, becoming the new standard. Data analyses focused on characterising changes in neural processing of the visual stimuli as a function of the expectation violation in the unrelated, auditory modality.
