研究背景尽管口语对话中话轮转换的研究已经非常丰富，但与话轮结束预期相关的典型脑电信号至今尚未被发现。我们的目标是确定的前意识发作的转折结束的预期在早期，前意识转折结束的预期过程中，同时注册的EEG措施（RP）和行为的措施（预期时间的准确性，ATA）。对于我们的行为测量，我们使用按钮按下和口头反应（“是”）。在实验中，30名受试者被要求听一段简短的话语，当他们预期回合结束时，按一个按钮或说出一个简短的口头回应。在任务期间，一个32通道的EEG信号recorded.ResultsThe结果表明，在口头和按钮按下反应的RP开发类似，并有一个几乎相同的时间过程：RP信号在行为响应之前1170 vs. 1190 ms开始发展。与现有方法的比较到目前为止，通常使用行为方法来研究转向端预测，例如通过测量预期定时精度，这是一个测量，反映了有意识的行为过程，是不敏感的前意识的预期过程。新闻回应提供了证据的有效性，使用RP作为一个在线标记的反应准备在话轮转换和口语对话研究。
BackgroundEven though research in turn-taking in spoken dialogues is now abundant, a typical EEG-signature associated with the anticipation of turn-ends has not yet been identified until now.New methodThe purpose of this study was to examine if readiness potentials (RP) can be used to study the anticipation of turn-ends by using it in a motoric finger movement and articulatory movement task. The goal was to determine the preconscious onset of turn-end anticipation in early, preconscious turn-end anticipation processes by the simultaneous registration of EEG measures (RP) and behavioural measures (anticipation timing accuracy, ATA). For our behavioural measures, we used both button-press and verbal response (“yes”). In the experiment, 30 subjects were asked to listen to auditorily presented utterances and press a button or utter a brief verbal response when they expected the end of the turn. During the task, a 32-channel-EEG signal was recorded.ResultsThe results showed that the RPs during verbal- and button-press-responses developed similarly and had an almost identical time course: the RP signals started to develop 1170 vs. 1190 ms before the behavioural responses.Comparison with existing methodsUntil now, turn-end anticipation is usually studied using behavioural methods, for instance by measuring the anticipation timing accuracy, which is a measurement that reflects conscious behavioural processes and is insensitive to preconscious anticipation processes.ConclusionThe similar time course of the recorded RP signals for both verbal- and button-press responses provide evidence for the validity of using RPs as an online marker for response preparation in turn-taking and spoken dialogue research.
