<P> Most language production and processing occur in the left hemisphere while the majority of the emotional processing and production of emotion in speech occurs in the right hemisphere . Schizophrenic patients usually have difficulty processing prosody . These patients also show a remarkable increase in lateralization towards the right hemisphere of both emotionally and non-emotional prosody rich speech . Also, a decrease in right - handedness led to an increase in the right hemisphere lateralization . This right hemisphere lateralization extends beyond prosody to many of aspects of language and speech processing in schizophrenic patients . </P> <P> The two hemispheres have a complementary specialization for control of different aspects of emotion . a) Left hemisphere primarily process "positive" emotions and right hemisphere primarily process "negative" emotions . A large portion of regions primarily in the right hemisphere are activated during aversive classical conditioning . </P> <Dl> <Dd> <Dl> <Dd> While this theory seems to hold true for some emotions, this theory is generally considered outdated; however a few examples exist . For example, a study found that when subjects were primed with positive stimuli before hearing a consonant, the left hemisphere was more active than the right hemisphere . In contrast, when subjects were primed with a negative stimulus, the right hemisphere was more active than the left hemisphere . </Dd> </Dl> </Dd> </Dl> <Dd> <Dl> <Dd> While this theory seems to hold true for some emotions, this theory is generally considered outdated; however a few examples exist .
