Embodiment Construction
[0035] The present invention will be further described below in conjunction with specific examples.
[0036] The method for assessing auditory shock based on the brain-computer interface assisted CRS-R scale described in this embodiment is as follows:
[0037] 1) Stimulus selection, arrangement and experimental paradigm design
[0038] Based on the auditory novelty experimental paradigm, two types of sound stimuli, standard and deviation, are selected to be as close as possible to the evaluation method of the CRS-R behavior scale, and because compound sounds are more likely to induce mismatch waves in brain-injured patients than single sine tones, The standard and deviation stimuli were recorded with ambient background noise (40dB) and clapping (90dB), respectively, and appeared randomly in each stimulus sequence at a ratio of 4:1. Each subject completed at least 10 tasks, specifically 10 in this embodiment, and a single task included at least 5 repetitions of stimulation seq...
