The EEG signals of 30 normal samples and 30 patient samples are collected. Based on the preprocessing for the raw data, a computational program for complexity measure is compiled and the complexity measures of all samples are calculated. The mean value and standard error of complexity measure of control group is as 0.33 and 0.10, and the normal group is as 0.53 and 0.08. When the confidence degree is 0.05, the confidence interval of the normal population mean of complexity measures for the control group is (0.2871,0.3652), and (0.4944,0.5552) for the normal group. The statistic results show that the normal samples and patient samples can be clearly distinguished by the value of measures. In clinical medicine, the results can be used to be a reference to evaluate the function or state, to diagnose disease, to monitor the rehabilitation progress of the brain.展开更多

The major research questions posed are: 1. Are there any significant differences between the five variables of the two groups of students? 2. Are there any correlations between each of the five variables of the two groups? 3. Does language or learning attitude correspond with the students' reading ability? The resulting statistics indicated that there are both positive and negative correlations between all of the five variables of the two groups.There are significant differences between the two groups in the two key variables (reading comprehension). The female students have a more positive attitude towards the English language than the male students, while the male students have a more positive attitude toward the English learning process than the female students. Language or learning attitude corresponds with the students' reading ability.展开更多
