Sex difference in susceptibility to DAF (delayed auditory feedback) in oral reading of texts was investigated. Forty adults, 20 males and 20 females with normal speech and hearing abilities, read aloud two kinds of texts, one easy to read and the other difficult, under two conditions, NAF (normal auditory feedback) and DAF. Delays were 150, 200, 300, 400 and 500 ms and the feedback intensity was 90 dB in SPL at maximum. Susceptibility to DAF was defined as max magnitude of DAF Index under five DAF conditions (DAF Index = 1-CMR(tau)/CMR(0), where CMR was correct mora rate per second and tau the delay). As the results, the susceptibility was significantly higher in males than in females for easy texts. Sex difference of the feedback mechanism for articulation was clearer in easy texts than in difficult ones. It was suggested that the articulatory movement was more cognitively controlled by the route of auditory feedback in males than in females.
研究了在朗读文本时对延迟听觉反馈（DAF）易感性的性别差异。40名成年人，20名男性和20名女性，具有正常的言语和听力能力，在两种条件下大声朗读两种文本，一种易于阅读，另一种难度较大，这两种条件分别是正常听觉反馈（NAF）和延迟听觉反馈（DAF）。延迟时间分别为150、200、300、400和500毫秒，反馈强度最大为声压级90分贝。对DAF的易感性定义为五种DAF条件下DAF指数的最大幅度（DAF指数=1-CMR（τ）/CMR（0），其中CMR是每秒正确的音节率，τ是延迟时间）。结果表明，对于简单文本，男性的易感性明显高于女性。在简单文本中，发音反馈机制的性别差异比在困难文本中更明显。这表明男性的发音运动比女性更多地受到听觉反馈途径的认知控制。
