The psychometric characteristics of Standard-Chinese lexical neighborhood test (LNT) confirmed the lexical effects of the four word categories. The established normative baseline can be used in evaluating the word-recognition performance of the hearing-impaired listeners.
The purpose of the present study was to examine the psychometric characteristics and evaluate the reliability of Standard-Chinese LNT in children and adults.
Twenty-six normal-hearing adults and 13 normal-hearing children were recruited. Word recognition was tested with the Standard-Chinese LNT materials that consisted of four types of word list: monosyllable easy words, monosyllable hard words, disyllable easy words, and disyllable hard words.
The thresholds at 50% correct performance for the easy word lists and disyllable word lists were lower than those for the hard word lists and monosyllable word lists, respectively (all p < 0.001). The slopes for disyllable words were steeper than the monosyllable words (p < 0.05). In addition, the recognition threshold of the four categories for children was higher than that for adults (all p < 0.05). The critical difference was on average 26.6% for adults and 30.0% for children.
标准中文词汇邻域测试（LNT）的心理测量特征证实了四类词的词汇效应。既定的规范基线可用于评估听力受损听众的单词识别表现。
本研究的目的是检验标准中文LNT在儿童和成人中的心理测量特征并评估其可靠性。
招募了26名听力正常的成年人和13名听力正常的儿童。使用标准中文LNT材料进行单词识别测试，该材料由四种类型的单词列表组成：单音节易词、单音节难词、双音节易词和双音节难词。
易词列表和双音节词列表在正确率为50%时的阈值分别低于难词列表和单音节词列表的阈值（所有p<0.001）。双音节词的斜率比单音节词更陡（p<0.05）。此外，儿童四类词的识别阈值高于成人（所有p<0.05）。成人的临界差异平均为26.6%，儿童为30.0%。
