Emotions In Music

The study under discussion sought to investigate the hemispheric laterality of musical emotions: Is one hemisphere of the brain preferentially involved in recognizing emotions in music? The authors took a neuropsychological approach to answer this question by studying emotional judgments of music in people with brain damage to either hemisphere. Their results indicated that individuals with left hemisphere damage were significantly impaired in recognizing musical emotions as compared to healthy comparison participants. In contrast, individuals with right hemisphere damage were not impaired at identifying emotions in music, but rated the perceived intensity of the emotions lower for sadness and fear (as compared to joy and serenity). Their work suggests that the identification of emotions in music and the perceived intensity of the emotions expressed may rely on different hemispheres of the brain.

Fluency Task

ABSTRACT Purpose The aim of this study is to analyze and compare the performance and strategies used by control subjects and patients with unilateral brain damage on phonemic and semantic Verbal Fluency tasks. Methods The sample consisted of 104 participants divided into four groups (26 with left hemisphere damage and aphasia- LHDa, 28 with left hemisphere damage and no aphasia- LHDna, 25 with right hemisphere damage- RHD and 25 neurologically healthy control subjects). All participants were administered the phonemic (“M” letter-based) and semantic (animals) verbal fluency tasks from the Montreal-Toulouse Language Assessment Battery (MTL-BR). Results Patients in the LHDa group showed the worst performance (fewer words produced, fewer clusters and switches) in both types of fluency task. RHD group showed fewer switching productions when compared with controls and LHDna had fewer words productions than controls in the first 30 seconds block. Conclusion Our findings suggest that the LHDa group obtained lower scores in most measures of SVF and PVF when compared to the other groups.

Insight Into

Since signed languages utilize visual-gestural channels, their study allows a unique opportunity for insight into the ways language and gesture may be represented in the brain. The separability of apraxia and aphasia for sign language was examined in four deaf signers who had unilateral brain damage, three to the left hemisphere and one to the right hemisphere. These patients were administered various tests for apraxia and a test of pantomime recognition. The patient with damage to the right hemisphere was not apraxic as we would expect. For the patients with damage to the left hemisphere, all of whom were aphasic for sign language, strong dissociations emerged between their capacities for sign language and their nonlinguistic motor skills. The language deficits of these patients seemed related to specific linguistic components of sign language rather than to an underlying motor disorder or an underlying disorder in the capacity to express and comprehend symbols of any kind. This separation between linguistic and nonlinguistic function is all the more striking, because sign language and gesture are transmitted in the same modality.

A 96-trial tachistoscope recognition task was given to 15 left-hemisphere-damaged, 12 right-hemisphere-damaged, and 30 non-brain-damaged subjects. Procedure called for a first stimulus presented for 250 msec. a 1-sec. pause, and a second stimulus for 250 msec. The stimuli were 12 animal drawings used in repeated series according to a random schedule. Six animals were familiar and six were novel. For half of the trials, the two pictures were of different animals. Size and position of the animal picture were controlled. Both reaction time and accuracy were independently scored. Judgments of same and different appear to function as if they are governed by different processes. For the control group, measures of same and different judgments do not correlate highly despite high internal consistency of subtests. Recognition of same becomes impaired with brain damage, but more so if the damage is rightsided. Recognition of different judgments shows considerably less sensitivity to the effects of unilateral brain damage.

Reading and spelling performance was analysed for a sample of 45 children with unilateral brain damage. Boys showed impairments only when the lesion was on the left, while girls showed no significant impairments when either hemisphere was affected. The results support the hypothesis that specialised substrates, which underlie literacy acquisition, have limited plasticity and may be more strongly lateralised to the left hemisphere in males than in females.

AbstractThe study aimed at investigating lateralization effects and signs of transfer and crowding in children with congenital lateralized brain damage with the aid of a dichotic listening test, a chimeric test, and verbal and nonverbal neuropsychological tests. Thirty-three children with spastic hemiplegia and 86 control children (age 5.0–12.0 yr) were assessed. Children with left-hemisphere damage (n = 17) were found to have a pathological left-ear advantage for verbal material, and children with right-hemisphere damage (n = 16) were found to have a pathological right visual half-field advantage for visual material. Children with left-hemisphere damage and a left-ear advantage on the dichotic test were also found to have a right visual half-field advantage on the chimeric test, which was regarded as a sign of reversed dominance. No verbal or nonverbal differences emerged between the left-hemisphere and the right-hemisphere damage groups, nor did differences emerge when the children were reclassified by considering children with left-hemisphere damage and signs of reversed dominance as having damage to the nondominant hemisphere. It was concluded that although lateralized brain damage may alter the dominance for verbal and visual functions, there is still considerable inter-individual variability with respect to inter- and intrahemispheric neural adjustment to damage. The dichotic and the chimeric tests did not indicate the presence of brain damage accurately, but they indicated the lateralization of damage in children with stated abnormality with a high degree (91.3%) of accuracy.

ABSTRACTComprehension of six dimensional adjectives was found to be intact in groups of left hemisphere-damaged, right hemisphere-damaged and neurologically normal patients. Phrases with those adjectives were interpreted quite differently by left hemisphere-damaged patients than by the other two groups, and a subgroup of left-damaged patients appeared to be responsible for that group's deviant responses to phrases such as slightly bigger. All patients in the left-damaged group had some difficulty with negative phrases such as not big, however. Patients with right hemisphere-damage had difficulty interpreting only negative phrases with small. Results are interpreted with reference to Luria's discussion of semantic aphasia, and with regard to recent findings concerning the role of the right hemisphere in language comprehension.

Recovery and neural reorganization after congenital left- and right-brain injury is assessed on dichotic listening and tachistoscopic visuo-perceptual tasks. A matched-pair approach for age and type of lesion is used. Over-all, deficits are less pronounced than in adults. Innate specialization of both left and right hemispheres is supported by the data. In addition, a left-right maturational gradient is suggested by the all-around better performance of the child with left-hemisphere pathology. The later maturing, relatively less-committed right hemisphere is better able to compensate after unilateral injury.

The taxonomy proposed by Pessoa et al. should be extended to include “pathological” completion phenomena in patients with unilateral brain damage. Patients with visual field defects (hemianopias) may “complete” whole figures, while patients with parietal lobe damage may “complete” partial figures. We argue that the former may be consistent with the brain “filling-in” information, and the latter may be consistent with the brain ignoring the absence of information.
