Title: A computational approach to predict human sequence learning in
reaction time experiments

Abstract:

I study human sequence learning in a task where participants typically sit
in front of a computer screen on which visual signals appear at different
locations. Participants are asked to react to these signals as quickly as
possible by pressing particularly designated keys on their keyboard. What
they initially do not know is that the signals flash in a particular
sequential order, where previous signals predict following ones. Speeded
reaction times and improved accuracy can tell which signals are anticipated.
After the first experiments, I analyzed the strategies that participants
typically apply in this task. I then created a computational model that was
based on this analysis. This model was cross-validated with future
experimental data by testing whether it would correctly predict human
learning in six further experiments.
