The hypothesis that music training can improve verbal memory was tested in children. The results showed that children with music training demonstrated better verbal but not visual memory than did their counterparts without such training. When these children were followed up after a year, those who had begun or continued music training demonstrated significant verbal memory improvement. Students who discontinued the training did not show any improvement. Contrary to the differences in verbal memory between the groups, their changes in visual memory were not significantly different. Consistent with previous findings for adults (A. S. Chan, Y. Ho, & M. Cheung, 1998), the results suggest that music training systematically affects memory processing in accordance with possible neuroanatomical modifications in the left temporal lobe.

Confrontation naming of 52 unilateral or bilateral brain-damaged Chinese patients were examined with a modified version of the Boston Naming Test (BNT). Chinese patients with left or right hemisphere lesions, contrary to studies on English speakers, demonstrated similar levels of naming impairments, supporting the notion that English and Chinese are mediated by different neuroprocessing systems. In addition, the psychometric properties of the BNT on Chinese population were examined. While the test demonstrated satisfactory internal consistency and discriminant validity, level of education was found to be a significant factor affecting participants' performance. A cut-off score of 24 in spontaneous naming yielded a sensitivity of 73.1% and specificity of 75.3% in differentiating normal from brain-damaged participants, suggesting that the modified BNT is applicable to the Chinese population.

Self-control problems commonly manifest as temper outbursts and repetitive/rigid/impulsive behaviors, in children with autism spectrum disorders (ASD), which often contributes to learning difficulties and caregiver burden. The present study aims to compare the effect of a traditional Chinese Chan-based mind-body exercise, Nei Yang Gong, with that of the conventional Progressive Muscle Relaxation (PMR) technique in enhancing the self-control of children with ASD. Forty-six age- and IQ-matched ASD children were randomly assigned to receive group training in Nei Yang Gong (experimental group) or PMR (control group) twice per week for four weeks. The participants’ self-control was measured by three neuropsychological tests and parental rating on standardized questionnaires, and the underlying neural mechanism was assessed by the participants’ brain EEG activity during an inhibitory-control task before and after intervention. The results show that the experimental group demonstrated significantly greater improvement in self-control than the control group, which concurs with the parental reports of reduced autistic symptoms and increased control of temper and behaviors. In addition, the experimental group showed enhanced EEG activity in the anterior cingulate cortex, a region that mediates self-control, whereas the PMR group did not. The present findings support the potential application of Chinese Chan-based mind-body exercises as a form of neuropsychological rehabilitation for patients with self-control problems.

WITH AN estimated incidence rate of 10 to 30 cases per 100,000 persons, nasopharyngeal carcinoma (NPC) is diagnosed in about 1000 people every year in Hong Kong, China. Although chemotherapy is sometimes used, radiotherapy remains the main treatment for NPC. Although the tumor receives the highest dosage of radiation, normal brain tissues along the pathway and brain structures in proximity to the nasopharynx are within the target volume. It is documented that the brainstem, upper cervical spinal cord, cranial and cervical sympathetic nerves, and inferomedial parts of the temporal lobe are exposed to radiation.1-3

The present study examined quantitative electroencephalographic (QEEG) profile for children with autistic spectrum disorder (ASD). Five-minute QEEG data were obtained from 90 normal controls (NCs) and 66 children with ASD. Spectrum analyses revealed that ASD children showed significantly less relative alpha and more relative delta than NC. Specifically, 26% of ASD children and 2% of NCs showed 1.5 SDs of relative alpha below the normative mean. Children with this QEEG profile had 17 times the risk of having ASD than those without such a profile. Sensitivity and specificity of relative alpha were 91% and 73%, respectively. Split-half cross-validation yielded a sensitivity of 76%.
