一项字母搜索任务被用来检验词缀在形态加工过程中被组块的假设，以及这种组块对前缀和后缀的操作可能不同。参与者必须检测嵌入在前缀或后缀中的字母目标(例如，ProPoint或电影中的R)，或者非前缀开始或非后缀结束中的字母目标(例如，Cropoint或电影中的R)。带前缀和后缀的字母串--由真正的词干和词缀组成，但从来没有形成一个真正的单词。此外，还通过操纵非词缀的开头和结尾的频率来考察字母簇频率的影响。与非后缀词尾相比，字母搜索在后缀中花费的时间更长，但与非前缀词头相比，前缀的搜索时间并不长。此外，字母串的频率并不影响性能。我们根据最近对形态正字法切分和前缀和后缀的不同功能的描述来解释我们的发现。
A letter-search task was used to test the hypothesis that affixes are chunked during morphological processing and that such chunking might operate differently for prefixes and suffixes. Participants had to detect a letter target that was embedded either in a prefix or suffix (e.g., 'R' in propoint or filmure) or in a non-prefix beginning or non-suffix ending (e.g., 'R' in cropoint or filmire). Prefixed and suffixed letter-strings comprised real stems and affixes but never formed a real word. Effects of letter cluster frequency were also investigated by manipulating the frequency of non-affix beginnings and endings. Letter search took longer in suffixes compared with non-suffix endings but not for prefixes compared with non-prefix beginnings. Moreover, performance was not affected by letter cluster frequency. We interpret our findings in the light of recent accounts of morpho-orthographic segmentation and the different function of prefixes and suffixes.
