一个实验被用来研究在先前的研究中发现的慢皮质电位(SCP)的自我调节(Elbert等人)。1979年)。受试者(17人)每隔6分钟就会收到连续的视觉反馈，当火箭在电视屏幕上移动时，可以感觉到他们的实际大脑皮层移动；受试者必须根据两个信号音的音高，将火箭引导到代表大脑皮层或多或少负面的2个目标中的1个。在两个相同的实验阶段中，反馈试验和无反馈试验交替进行。在所需的两个极性之间，SCP显示出极显著的差异。最显著的差异是在第二次没有反馈的测试试验中观察到的，在第二次会议中，当需要积极(或较少的消极)时，发生了低于基线水平的积极转变。
An experiment was performed to investigate the self-regulation of slow cortical potentials (SCP) found in a previous study (Elbert et al. 1979). Human subjects (17) received continuous visual feedback of their actual cortical shift perceptible as a rocket moving across a TV-screen during intervals of 6 s; subjects had to direct the rocket into 1 of 2 goals representing more or less cortical negativity, depending on the pitch of 2 signal tones. Within 2 identical experimental sessions feedback trials alternated with test trials without feedback. Highly significantly differences of SCP between the 2 required polarities were demonstrated. The most pronounced differences were observed during test trials without feedback of the 2nd session in which a positive shift below baseline level occurred when positivity (or less negativity) was required.
