Asymmetries in activation and arousal may contribute to lateralised effects of habituation and contingency learning during a repetitive choice reaction time task

This study presents experimental data that suggest possible hemispheric asymmetries in contingency learning and habituation following irrelevant or warning stimuli during a discrimination reaction time task. A total of 68 college students participated in a letter-categorisation task (presumably engaging the left hemisphere more than the right hemisphere) and a visuospatial task (presumably engaging the right hemisphere more than the left...
