Data_Sheet_1_A Lexical Representational Mechanism Underlying Verbal Satiation: An Empirical Study With Rarely Used Chinese Characters.docx

High repetitions of a character induce a feeling of uncertainty of the character. This phenomenon is named as Verbal Satiation. However, the locus and nature of the verbal satiation remain controversial. To investigate whether verbal satiation occurs at the lexical representational locus, we used rarely used Chinese characters as stimuli to exclude confounding factor of meaning access. Participants were asked to judge whether or not a single Chinese character such as “” is a composition of a rarely used Chinese character such as “.” The experiment consists of 4 sets with 11 blocks in each set. Every 20 trials consist of a block, and the same rarely used characters were repeated in half of these trials. To observe the satiation effect that is offset by practice effect with more statistical power, we did ANOVA analysis for each set. The statistical results revealed that subjects responded differently at different time periods. In the first set, participants responded faster in later trials; After that, reversely, participants responded slower in later trials; Then they responded slower for the repeated characters in middle trials; Finally, participants responded slower for the repeated characters without regard to the trial position. These results show a competition process between satiation effect and practice effect and reveal that the verbal satiation can occur at a lexical representational locus.

字符的高频重复引发了对该字符的不确定性感知，此现象被称为言语饱和。然而，言语饱和的定位与本质仍存在争议。为探究言语饱和是否发生在词汇表征层面，我们以不常用的汉字作为刺激，排除了意义获取的干扰因素。参与者被要求判断单个汉字，如“”，是否由不常用的汉字，如“。”构成。实验分为4组，每组包含11个区块。每个区块包含20次试验，其中一半试验重复使用相同的不常用字符。为了观察由练习效应抵消的饱和效应，并具备更强的统计学效力，我们对每组进行了方差分析。统计分析结果表明，参与者在不同时间段内的反应存在差异。在第一组中，参与者在后续试验中反应更快；随后，反而在后续试验中反应变慢；接着，在中期试验中对重复字符的反应变慢；最后，无论试验位置如何，对重复字符的反应均变慢。这些结果展示了饱和效应与练习效应之间的竞争过程，并揭示了言语饱和可以发生在词汇表征层面。
