Cognitive performance
Cambridge Neuropsychological Test Automated Battery (CANTAB)is a computerized, language and culture-free neuropsychological cognitive testing tool that is non-verbal in the vast majority of tasks, including geometric and simple patterns and machine sounds. CANTAB is considered by researchers to be the latest generation of neuropsychological cognitive detection tools and has been widely used in the field of neuropsychiatric research abroad [PRM: The test is divided into two stages. The first stage is the immediate mode, the center of the screen at a rate of 1 per second after the presentation of 12 graphics. In the re-recognition stage, the patient is required to choose between the pattern that has been seen and a new shape, select the pattern seen; the second stage is the delay mode, the center of the screen will display 12 new graphics, the patient also needs to carefully observe and remember, after 20 min, and then let the patient select the pattern seen. PRM primarily tests visual short-term recognition memory. The test indicators are immediate mode accuracy and delay mode accuracy. The higher the correct rate, the better the patient’s visual recognition memory.IED: The quiz is a test of the subject’s ability to acquire and convert rules and the maintenance, conversion, and flexibility of attention. During the operation, two graphics will appear in the middle of the computer screen, one is right, and the other is wrong. The emergence of the graph is a certain law. The rules or graphs will change after six consecutive correct clicks on the graph. The first time the subject needs to produce the correct graph, and then the subject needs to summarize and find out what the law is, the correct graph is selected. The transformation of the rule is from the initial internal dimension to the external dimension. Subjects must meet the prescribed criteria at each stage to move on to the next stage. The test indicators are the number of errors in the previous period of external conversion, the number of errors in the external conversion period, the number of completed stages, and the total number of errors. The number of errors in the external dimension conversion stage reflects the patient’s ability to pay attention to the conversion of the complete set, which is used to illustrate the flexibility and execution control problems when the task needs to be changed, and the total number of corrected errors includes the number of errors in the external dimension conversion stage and the number of completed stages, which is a comprehensive indicator of the quality of the attention set conversion task.
