Design outcomes

Primary

MeasureTime frame
Interference is the relative processing speed, which is most simply argued as the fact that faster processes can affect slower ones, but the opposite is not true. Timepoint: The evalution of this variable was when patient only receive drug therapy and didn't receive psychological. Method of measurement: Computerized Stroop Test evaluates the capacity to attend to specific characteristics of a stimulus, ignoring characteristics irrelevant to the task. In this test, 48 matching and 48 mismatching colored words (red, blue, yellow and green) were shown to the subjects. The term matching words refers to the words whose color and name are the same, and mismatching words refer to those whose color and name are different. A total of 96 words were randomly and sequentially presented. The subjects were asked to say each word’s color, regardless of its meaning. Each stimulus was shown on the screen for two seconds, and the stimuli were presented at the intervals of 800 milliseconds. According to the researchers, the mismatching color-word task (second phase of the experiment) measured interference. The degree of interference was obtained by subtracting the number of correct mismatching words from that of correct matching ones.

Secondary

MeasureTime frame
Working memory resources include verbal and visual working memory. Visual memory plays a key role in the formation and manipulation of mental images. On the other hand, verbal memory covers the phonological loop. The verbal information provided verbally enters the phonological loop directly, immediately and automatically, and is stored phonologically for a short time. Timepoint: The evalution of this variable was when patient only receive drug therapy and didn't receive psychological. Method of measurement: Wechsler Memory Scale - Third Edition (WMS-III) has 18 subscales (11 primaries and 7 optional subscales), and 8 scores are obtained from the 11 primary subscales. In this research, only two subscales were used to measure verbal and visual working memory. Visual Memory Subscale is a visual rehabilitation test, in which the subject is asked to use his/her memory to draw the simple shapes provided to him/her for 10 seconds. The total scores of forward and reverse digit span subtest were also used to measure verbal working memory.
