不相关声音效应(ISE)是一项发现,与白噪音或沉默相比,在复杂的听觉背景下(如讲话),连续回忆的表现会受到损害。一些研究结果表明,ISE发生在非言语背景下,背景刺激的变化状态复杂性对ISE至关重要(例如,)。在两个实验中,我们研究了不相关背景的类语音品质是否具有超出其变化状态复杂性的影响。我们通过使用两种具有相同状态变化复杂性的语音转换来实现;一种是保留类似语音的信息(正弦波语音和完全反转的正弦波语音),另一种是信息失真(两种选择性反转的正弦波语音条件)。我们的研究结果表明,即使在变化状态复杂性保持不变的情况下,类语音干扰关系被破坏的正弦波语音条件产生的ISE也比这些关系保持不变的正弦波语音条件产生的ISE要少。这表明,对于ISE来说,背景的类语音属性比它们的状态变化复杂性更重要。
The Irrelevant Sound Effect (ISE) is the finding that serial recall performance is impaired under complex auditory backgrounds such as speech as compared to white noise or silence. Several findings have demonstrated that ISE occurs with nonspeech backgrounds and that the changing-state complexity of the background stimuli is critical to ISE (e.g.,). In a pair of experiments, we investigate whether speech-like qualities of the irrelevant background have an effect beyond their changing-state complexity. We do so by using two kinds of transformations of speech with identical changing-state complexity; one kind that preserved speech-like information (sinewave speech and fully-reversed sinewave speech) and others in which this information was distorted (two selectively-reversed sinewave speech conditions). Our results indicate that even when changing-state complexity is held constant, sinewave speech conditions in which speech-like interformant relationships are disrupted produce less ISE than those in which these relationships are preserved. This indicates that speech-like properties of the background are important beyond their changing-state complexity for ISE.
