The present study was conducted to verify a promising experimental setup which demonstrated an inversed Stroop-effect (much faster responses for incongruent relative to congruent Stroop trials) following a mismatching tone. In the matching condition, which was an almost exact replication of the original study, participants were required to indicate whether word color and word meaning were matching, whereas in the response conflict condition, instruction was the same as in a classical Stroop task and required the participants to respond to the word color. As in the original study, each trial was preceded by a sine tone which was deviant in pitch in 20% of the trials. The main result was that the Stroop effect was not inversed after deviant tones, neither under the matching task instruction nor under the response conflict task instruction. The Stroop effect was unaffected by the previous "conceptual mismatch." The current study failed to replicate the astonishing concept of "conflict priming" reported in previous work and does not open the doors for a new window on sequences of conflicts. Nevertheless, the failed replication is valuable for future research, since it demonstrated that "Conflict Priming" as a facilitation of processing of conflict trials following deviant tones, is not an confirmed finding.
本研究旨在验证一种有前景的实验设置,该设置显示在不匹配音调后出现了反向斯特鲁普效应(相对于一致的斯特鲁普试验,不一致的试验反应快得多)。在匹配条件下,这几乎是对原始研究的精确复制,要求参与者指出单词颜色和单词含义是否匹配,而在反应冲突条件下,指令与经典斯特鲁普任务相同,要求参与者对单词颜色做出反应。与原始研究一样,每次试验之前都会有一个正弦音调,其中20%的试验音调在音高上是异常的。主要结果是,在异常音调之后,无论是在匹配任务指令下还是在反应冲突任务指令下,斯特鲁普效应都没有反转。斯特鲁普效应不受先前“概念不匹配”的影响。当前研究未能重复先前工作中报道的令人惊讶的“冲突启动”概念,也没有为冲突序列打开一扇新窗口。然而,失败的重复对未来研究很有价值,因为它表明“冲突启动”作为一种促进异常音调后冲突试验处理的现象,并不是一个已证实的发现。
