뇌파 조건화가 정신지체아동의 주의집중 및 기억학습에 미치는 효과

다국어 초록 (Multilingual Abstract)

Fifty one students with mental retardation of elementary, middle and high special schools participated in an experiment investigating the effects fo brain wave conditioning by lights and sounds on their attention and memory to find implications of intervention for attention deficit and lack of memory problems in this population. Using a matched allocation based on digit spans, the student were randomly assigned to one of three conditions: children's video-tape watching (control group), adjustable brain wave learning(experimental group 1), and nonadjustable brain wave learning(experiment group 2). They participated in the experiment for five weeks. Pretests were conducted just before the experiment, and post tests were conducted at the end of six weeks. Follow-up tests were conducted two months after the experiment. Results indicated that the adjusted brain wave conditioning by lights and sounds increased the short-term memory by auditory stimuli of the students with mental retardation. It was not found to increase the attention of the students due in part to lack of controlling environmental variables that disturbed the class during the post tests. The results also demonstrated that the brain wave conditioning had no effect on increasing the picture recognition by visual stimuli. The brain wave resonance training using the brain wave learning system was found to mildly increase the alpha and theta waves considered to be related to learning and memory and reduce the amplitude of waves considered to be related to attention. However, the training was not found to reduce the frequency of the brain wave.
