operators have a rightear superiority for the perception. of the codeeven
though the sounds are distinguished only by their. temporal structure..
Rudel and coworkers found that both blind and sighted subjects read.
Braille more rapidly with the left hand.Some children are actually.
fluent readers with the left hand but are totally unable to read with. the
right.Because Braille patterns are spatial configurations of dots. this
observation is congruent with the proposal that the right. hemisphere
has a role in processing spatial information that is not. shared by the
left.. Candace Gibson and Phil Bryden presented subjects with cutouts
of. irregular shapes or letters made of sandpaperwhich were moved
slowly. across the fingertips.Their subjects showed a righthand advan
tage. for identifying letters and a lefthand advantage for denti fying.
other shapes.. The right side of the mouth opens wider and more
quickly than the. left for both verbal and nonverbal tasks.Goodale s
observations. support the idea that the left hemisphere has a special role
in the. selectionprogramming and production of verbal and nonverbal
oral. movements. Is there an analogous role for the right
hemisphereIndeed. there is. Considerable evidence shows that the left
side of the face. displays emo tions more strongly than the right sideand
Goodale. showed that the onset of facial expressions occurs sooner on
the left. side of the face.. What Is Lateralized It is tempting to conclude
that the functional. asymmetries described thus far indicate a
fundamental difference in. the basic cognitive processes of the left and
right cerebral. hemispheres. Howeverbefore turning to this matterwe
will consider a. summary of the databecause any theoretical statements
are best. considered in light of available information. Table below
summarizes. the major data on cerebral lateralization and illustrates the
range of. functions lateralized principally n the left and right
hemispheres.In. righthanded peoplethe left hemisphere has a greater
role in language. and in the control of complex voluntary movements
than does the. right hemisphereand the right hemisphere has a greater
role in the. control of certain visuospatial and nonverbal abilities..
