本实验探讨了大学生惊吓眨眼的前脉冲抑制与视觉后向掩蔽的关系。据推测，从后向掩蔽效应的恢复部分是由于感觉门控，如听觉和视觉PPI评估。视觉呈现的字母作为目标或视觉前脉冲的混合会议的后掩蔽和PPI。在30、45、60、120和150 ms的刺激起始时间评估后向掩蔽和PPI（听觉和视觉）。 重复测量回归显示，对于视觉和听觉PPI，后向掩蔽和PPI之间存在关系，PPI水平越高，后向掩蔽的恢复越好。这些数据是一致的假设，即从后掩蔽效应的恢复是受感觉门控作用的一部分门的中断影响的面具。
This experiment demonstrated a relationship between prepulse inhibition (PPI) of the startle eyeblink and visual backward masking in college students. It was hypothesized thatrecoveryfrom backward masking effects is due in part to sensory gating, as assessed by auditory and visual PPI. Visual presentations of letters served as targets or visual prepulses in an intermixed session of backward masking and PPI. Backward masking and PPI (both auditory and visual) were assessed at stimulus onset asynchronies of 30, 45, 60, 120, and 150 ms. A repeated‐measures regression revealed that there was a relationship between backward masking and PPI for both visual and auditory PPI, with higher levels of PPI being associated with greater recovery from backward masking. The data are consistent with the hypothesis that recovery from backward masking effects is affected by sensory gating acting in part to gate out the interruptive effects of the mask.
