Recently, electrophysiological measures have been used to evaluate the functional overlap between semantic relations and laboratory-defined equivalence relations with abstract stimuli. Several studies using semantic judgment procedures have shown that accompanying EEG-measured neural activity for stimulus pairs from equivalence classes is very similar to that of word pairs from participants' native language. However, those studies often included pronounceable elements (e.g., written nonsense syllables) as at least one member of the experimentally defined classes. The present study conducted EEG studies that contrasted classes with and without such elements. Two groups of undergraduate students completed a matching-to-sample procedure to establish 3 4-member equivalence classes. For Group 1, samples and comparisons were pronounceable pseudowords and abstract figures. For Group 2, the matching-to-sample stimuli were abstract figures only. EEG data recorded during the semantic judgment tasks showed waveform patterns compatible with prior studies of semantic relations in Group 1 but not in Group 2.
最近，电生理测量被用于评估语义关系和实验室定义的抽象刺激等价关系之间的功能重叠。使用语义判断程序的几项研究表明，对于来自等价类的刺激对，伴随的 EEG 测量的神经活动与来自参与者母语的单词对非常相似。然而，这些研究通常包括可发音的元素（例如，书写的无意义音节）作为实验定义的类中的至少一个成员。本研究进行了 EEG 研究，比较了有和没有这些元素的类。两组本科生完成了一个匹配样本程序，以建立 3 个 4 成员等价类。对于组 1，样本和比较是可发音的假词和抽象图形。对于组 2，匹配样本刺激仅是抽象图形。在语义判断任务中记录的 EEG 数据显示出与组 1 中语义关系的先前研究兼容的波形模式，但与组 2 中的模式不兼容。
