The role of the cerebral hemispheres in specific versus abstract priming

The present study examined specific and abstract priming for pictures in unilateral brain-damaged patients using a picture fragment identification task. Participants were 10 posterior right hemisphere (RH) damaged patients, 11 posterior left hemisphere (LH) damaged patients, and 30 healthy normal co...

Description
Summary:The present study examined specific and abstract priming for pictures in unilateral brain-damaged patients using a picture fragment identification task. Participants were 10 posterior right hemisphere (RH) damaged patients, 11 posterior left hemisphere (LH) damaged patients, and 30 healthy normal controls. Results reveal that RH patients perform specific priming tasks significantly worse than healthy participants (p
