Frequency tagging has been successfully used to investigate selective stimulus processing in electroencephalography (EEG) or magnetoencephalography (MEG) studies. Recently, new projectors have been developed that allow for frequency tagging at higher frequencies (>60 Hz). This technique, rapid invisible frequency tagging (RIFT), provides two crucial advantages over low-frequency tagging as (i) it leaves low-frequency oscillations unperturbed, and thus open for investigation, and ii) it can render the tagging invisible, resulting in more naturalistic paradigms and a lack of participant awareness. The development of this technique has far-reaching implications as oscillations involved in cognitive processes can be investigated, and potentially manipulated, in a more naturalistic manner.
频率标记已成功用于研究脑电图（EEG）或脑磁图（MEG）研究中的选择性刺激处理。最近，开发了新的投影仪，可实现更高频率（>60 Hz）的频率标记。与低频标记相比，这项名为快速不可见频率标记（RIFT）的技术具有两个关键优势：（i）它不会干扰低频振荡，因此可以进行研究；（ii）它可以使标记不可见，从而产生更自然的范式，且参与者不会意识到。这项技术的发展具有深远的意义，因为可以更自然的方式研究涉及认知过程的振荡，并有可能对其进行操作。
