“阈下启动”实验的最新结果表明，无法被有意识地感知的隐藏启动刺激可以触发反应激活过程，但这些反应激活随后会受到抑制。通过操纵隐藏启动刺激的可见性，从清晰可见的启动刺激到意识感知无法接近的启动刺激，研究了有意识意识和反应抑制之间的联系。未察觉的启动刺激有反应抑制，而阈上启动刺激无反应抑制。个体启动识别阈值与反应抑制发生之间的相关性表明，有意识意识的缺失或存在可以预测是否引发反应抑制。这些结果显示了有意识和无意识信息在效果上的质的差异，认为有意识的感知信息产生的反应促进可以抵消自我抑制运动控制回路的自动效应。
Recent results from "subliminal priming" experiments have shown that masked prime stimuli which can not be consciously perceived can trigger response activation processes, but that these response activations can later be subject to inhibition. Links between conscious awareness and response inhibition were investigated by manipulating the visibility of masked prime stimuli, from clearly visible primes to prime stimuli that were inaccessible to conscious perception. Response inhibition was observed with unperceived prime stimuli, but not for suprathreshold primes. Correlations between individual prime identification thresholds and the onset of response inhibition indicate that the absence or presence of conscious awareness can predict whether or not response inhibition is elicited. These results demonstrate qualitative differences in the effects of conscious and unconscious information, It is argued that response facilitation produced by consciously available perceptual information can counteract automatic effects of self-inhibitory motor control circuits.
