Left handers
60% are left hemisphere dominant
30% are right hemisphere dominant
10% are mixed dominance
Left hemisphere - Right ear
- Processes speech sounds.
- A strong built in response to rapid sound changes.
Right hemisphere - Left ear
- Handles changes in tone.
- Preferation for tones.
|  | The left-hemisphere is considered to posses verbal intelligence, the complete lexicon and rules of syntax. Right-hemisphere-damaged patients, seldom have difficulties with phonology, syntax, or semantics, and will carry on a conversation which at first glance seems normal. It would seem that the left hemisphere is the ‘seat of language’.
Although over time, evidence has shown that the right-hemisphere, owns a number of very subtle ‘linguistic’ functions which are virtually synonymous with ‘poetry’ or ‘poetic’ speech. Indeed, one could assert that the degree of right-hemispheric involvement in language is what differentiates ‘poetic’ or ‘literary’ from ‘referential’ or ‘technical’ speech and texts.

children often have a preference for auditory input, with auditory
input often overshadowing visual input. The current research
investigated the developmental trajectory and factors underlying these
effects with 137 infants, 132 four-year-olds, and 89 adults. Auditory
preference reverses with age: Infants demonstrated an auditory
preference, 4-year-olds switched between auditory and visual
preference, and adults demonstrated a visual preference. Furthermore,
younger participants were likely to process stimuli only in the
preferred modality, thus exhibiting modality dominance, whereas adults
processed stimuli in both modalities. Finally, younger participants
ably processed stimuli presented to the nonpreferred modality when
presented in isolation, indicating that auditory and visual stimuli may
be competing for attention early in development. Underlying factors and
broader implications of these findings are discussed.(source: www.eric.ed.gov - pdf ) | |
