人类皮层电电位诱发的自我管理的听觉和视觉刺激表现出更小的幅度和更快的poststimulus的时间比平均大脑反应诱发相同的机器提供的刺激。听觉诱发电位比视觉反应在更大程度上表现出这种“自我刺激效应”。对于视觉诱发电位，这种效应在头顶联合区比在枕叶皮层更大。“自我刺激效应”大小的个体差异与智力水平有关。
Human electrocortical potentials evoked by self-administered auditory and visual stimuli manifest much smaller amplitude and faster poststimulus timing than do average brain responses evoked by identical machine-delivered stimuli. Auditory evoked potentials show this "self-stimulation effect" to a greater degree than do visual responses. For visual evoked potentials, the effect appears greater at the vertex association area than over the occipital cortex. Individual differences in the magnitude of the "self-stimulation effect" relate to level of intelligence.
