The Experiments

This is an annotated list of the published papers and meeting presentations that have played a key role in the development and experimental verification of the dimensional overlap model.  All the  experiments were performed in Dr. Kornblum’s  lab with the exception of the experiment reported in Kornblum et al (1999), which was performed in Dr. Jean Requin’s lab. at the CNRS in Marseille, France.  Each paper in the list below gives you the full citation of the article, a link to a summary of the article, and a quick set of key-word notes to let you know what issues are addressed by the paper. In some cases, clicking to view the summary of the article will also give you access to download the full PDF of the original manuscript.

The papers are presented in chronological order.
