The audiovisual bounce inducing effect (ABE) is a bouncing percept induced by the presentation of a sound in a motion display otherwise perceived as streaming. The literature suggests that the origin of the ABE is double: the effect stems from the action of an attentional component and that of a non-attentional component. However, the type of response classically gathered in ABE studies does not enable the disentanglement of the two components. Here, we used the ABE stimuli in a detection task and observed the effect of the sound on participants' sensitivity (hypothesised to be linked to the attentional component) and on response bias (hypothesised to be linked to the non-attentional component). The sound affected sensitivity and response bias in a way that is consistent with that expected by a selective modulation of the attentional and non-attentional component by the sound.
视听弹跳诱导效应（ABE）是指在原本被视为连续流动的动态显示中呈现声音时所诱发的一种弹跳感知。文献表明，ABE的起源有两个方面：该效应源于注意力成分和非注意力成分的作用。然而，ABE研究中传统上收集的反应类型无法区分这两个成分。在此，我们在一项检测任务中使用了ABE刺激，并观察了声音对参与者敏感度（假设与注意力成分相关）和反应偏差（假设与非注意力成分相关）的影响。声音对敏感度和反应偏差的影响方式与声音对注意力和非注意力成分的选择性调制所预期的一致。
