熟悉性对言语产生中语义效应的影响

Influences of Familiarity on the Semantic Effects in Parole Production

采用经典的图-词干扰范式,利用基本水平命名和类别水平命名两种任务,考察了图片和干扰词的熟悉性对言语产生中语义效应的影响。结果表明:1图片熟悉性影响图片的命名速度,高熟悉性图片命名快,低熟悉性图片命名慢,产生显著的图熟悉性效应;2干扰词熟悉性影响语义效应的强弱。在基本水平命名任务中,高熟悉性干扰词的语义干扰作用大,低熟悉性干扰词的语义干扰作用小;在类别水平命名任务中,高熟悉性干扰词的语义促进作用大,低熟悉性干扰词的语义促进作用小。干扰词的熟悉性与图-词间的语义关联性共同影响着言语产生中语义效应的方向和大小。本研究结果支持了词汇选择竞争假设的基本观点。

The influences of familiarity of pictures and interfering words on semantic effects in parole production have been investigated under classical picture-word interference paradigm and through tasks of basic level naming and type level naming. The results show that 1） picture familiarity interferes with the naming speed of picture. High familiarity leads to higher naming speed, and low familiarity to lower speed. There is obvious picture familiarity effect; and 2） the familiarity of interfering words has influences on the extent of semantic effects. In basic level naming task, high-familiarity interfering word has stronger interference, and low-familiarity interfering word has weaker interference. In type level naming task, high-familiarity interfering word has greater semantic promotion effect, while low-familiarity interfering word has smaller effect.The familiarity of interfering word and the correlation between picture and word co-affect the direction and the extent of semantic effects. Results of this study support the basic point-of-views in the hypothesis of lexical selection and competition.
