词汇决策任务中的标准假同音词效应，即与拼写控制相比，假同音词的反应时间更长，错误率更高，通常可以用正字法-音位冲突来解释。本研究采用多种方法，包括参与者的行为反应、信心评级、瞳孔反应和事件相关电位（erp），对这一冲突解释进行了检验。经典的假同音字效应是用相对较长的多音节刺激来复制的。假同音异义词被认为是非单词的自信程度低于拼写控制，而且它们通过增加瞳孔最大直径来影响瞳孔反应。这两个发现都可以解释为，在解决任务时，冲突的增加和认知需求的提高导致了不确定性。ERP显示了一个N400分量的拼写控制，呈现出分级效应：单词<伪同音字<拼写控制。这可以看作是通过假同音异义词（部分）语义激活的证据。综上所述，这些结果为假同音效应的冲突解释提供了强有力的多方法证据。2009爱思唯尔爱尔兰有限公司版权所有。
The standard pseudohomophone effect in the lexical decision task, i.e. longer response times and higher error rates for pseudohomophones compared with spelling controls, is commonly explained by an orthography-phonology-conflict. This study tested this conflict account, using a multi-method approach including participant's behavioral responses, confidence ratings, pupillary responses and event-related potentials (ERPs). The classic pseudohomophone effect was replicated using relatively long, multi-syllabic stimuli. Pseudohomophones were rated less confidently as being nonwords than spelling controls, and they affected the pupillary response by increasing the peak pupil diameter. Both findings are interpreted in terms of increased conflict and higher cognitive demands leading to uncertainty while solving the task. The ERP revealed an N400 component for spelling controls, showing a graded effect: word < pseudohomophone < spelling control. This can be seen as evidence for (partial) semantic activation through pseudohomophones. Taken together, the results provide strong multi-method evidence for the conflict account of the pseudohomophone effect. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
