Mouse-tracking, the analysis of mouse movements in computerized experiments, is a method that is becoming increasingly popular in the cognitive sciences. The
mousetrap package offers functions for importing, preprocessing, analyzing, aggregating, and visualizing mouse-tracking data.
mousetrap package is developed by Pascal Kieslich, Dirk Wulff, Felix Henninger, and Jonas Haslbeck. It is published under the GNU General Public License (version 3).
An overview of the functions in this package can be found online. It can also be accessed from within R using
package?mousetrap once the package has been installed. Please see news for a summary of changes in the package. Questions about using
mousetrap can be asked in the forum.
mousetrap package offers functions for importing mouse-tracking data in different formats and from various sources. One option to collect mouse-tracking data is by using the open-source graphical experiment builder OpenSesame in combination with the mousetrap-os plugin.
The current stable version is available on CRAN and can be installed via
To install the latest development version from GitHub, you need the
