揭示言语产生网络的组成部分的一个常见策略是使用先前在行为协议中测试过的心理语言学操作。这往往忽视了对解释行为不重要的实现方面如何影响神经反应。我们比较了两种流行的图片命名协议,涉及不熟悉的图片没有重复或重复熟悉的图片的电生理(EEG)签名。我们观察到显着的语义干扰的行为,但不是在脑电图的影响,相反的一些以前的研究结果。值得注意的是,这两种方案引起了明显不同的EEG反应。这些不是由于命名潜伏期差异,也没有反映出在试验时间窗内振幅的均匀调制。礼仪的效果是由于第一次接触材料所引起的熟悉。图片命名过程可以通过特定的协议要求进行实质性调整,这些协议要求由熟悉程度控制,并且在较小程度上由材料的重复控制。
A common strategy to reveal the components of the speech production network is to use psycholinguistic manipulations previously tested in behavioral protocols. This often disregards how implementation aspects that are nonessential for interpreting behavior may affect the neural response. We compared the electrophysiological (EEG) signature of two popular picture naming protocols involving either unfamiliar pictures without repetitions or repeated familiar pictures. We observed significant semantic interference effects in behavior but not in the EEG, contrary to some previous findings. Remarkably, the two protocols elicited clearly distinct EEG responses. These were not due to naming latency differences nor did they reflect a homogeneous modulation of amplitude over the trial time-window. The effect of protocol is attributed to the familiarization induced by the first encounter with the materials. Picture naming processes can be substantially modulated by specific protocol requirements controlled by familiarity and, to a much lesser degree, the repetition of materials.
