Abstract:In cognitive metaphor research a lot of different variables can exert their influence on the results. To control for all these variables limits the set of possible stimuli used. However, previous studies have already indicated that it may be possible to work with single word repetitions in psycholinguistic studies of language to broaden the set of possible stimuli. The effects of repeating stem sentences on the processing of language are less known. This study aims at expanding existing findings by examining the effect of repeating stem sentences on the processing of metaphorical, literal and anomalous expressions. Participants had to judge whether an expression was metaphorical, literal or anomalous, while N400 ERP responses were recorded. Repetition of stem sentences had no effect on the N400 amplitude. Reaction times were longest for first presentations of the stem sentences compared to second or third presentations. Unexpectedly, faster reaction times for anomalous sentences were found compared to metaphorical and literal sentences, which may be explained by task design. The findings from this study suggest, that it may be possible to work with repetition of stem sentences in psycholinguistic research, without compromising the validity of results.
