LSALAB

LSALAB is a software for working with semantic spaces.

It includes visual plotting of semantic relations, animation, ttest of semantic relations, downloading corpuses, etc.

Research interest

Neural network models of episodic memory and ERPs. I am interested in basic phenomena related to recognition and recall such as forgetting curves, the mirror effect, reaction times, serial position effect (primacy and recency), frequency effects, successive tests, etc. More details of my research interest.
