What is the nature of right hemisphere involvement in joke comprehension among neurologically intact individuals? One suggestion from researchers working with healthy
adults using the divided visual field (DVF) priming paradigm
is that RHD joke comprehension deficits may be related to
differences in the content of semantic activation in the left
and right cerebral hemispheres. The DVF paradigm involves
the presentation of written stimuli outside the center of gaze
in either the left or the right visual field so that it preferentially
stimulates the contra-lateral hemisphere (LVF/RH and
RVF/LH)
