SimpleDIVA App

This app allows the user to apply a simplified version of the DIVA model to data collected from auditory sensorimotor adaptation experiments. Specifically, the app takes as input a spreadsheet (csv format) that has one row per trial of the experiment. The first column should contain the perturbation value for each trial (as a decimal percentage; e.g., a 30% downward shift of F1 is -0.3), and each subsequent column contains data for an individual subject (one data point per trial per subject). The software then finds optimal fit values for three DIVA model parameters: an auditory feedback control gain, a somatosensory feedback control gain, and a trial-to-trial learning (adaptation) rate. The model’s fit to the data is then displayed, and statistics for the fit are provided. The resulting parameter values provide a mechanistic interpretation of the experimental data.

Additional instructions for installing and using SimpleDIVA can be found here.

NOTE: SimpleDIVA requires Matlab Runtime 2017b, a free software package that will be downloaded and installed on your computer (~2.8 GB of disk space) during the SimpleDIVA installation process. If Matlab Runtime 2017b is not already on your computer, you must be connected to the internet during installation of SimpleDIVA.

Current version [Version 1.2, May 14, 2020]

This version adds several pieces of functionality that are useful for fitting individual subject data, including the ability to adjust upper and lower bounds for individual parameters and regularization to deal with noisy single-subject data.
