Influence of capitalisation and presence of an article in noun phrase recognition in German: Evidence from eye-tracking

BackgroundGerman is exceptional in its use of noun capitalisation. It has been suggested that sentence-internal capitalisation as in German may benefit processing by specifically marking a noun and thus a noun phrase (NP). However, other cues, such as a determiner, can also indicate an NP. The influence of capitalisation on processing may thus be context-dependent, that is, dependent on other cues. Precisely this context dependency is investigated in the current study: Is there an effect of capitalisation on reading and is this affected by the presence of other cues such as a determiner (specifically, an article)? MethodsWe ran an eye-tracking study with 30 German-speaking adults, measuring fixations during sentence reading. Critical NPs either contained correctly capitalised nouns or not and were presented either with or without a determiner. ResultsThe results show that both the presence of capitalisation on the noun and the presence of a determiner led to faster reading. When no determiner was present to signal the NP, the presence of noun capitalisation aided reading most. ConclusionsFrom these results, we conclude that the influence of capitalisation is indeed context dependent: Capitalisation aids processing most when no other cue is present. Thus, different cues play a role in NP recognition. Based on these findings, we argue that noun capitalisation should not be studied in isolation. We argue that a better understanding of capitalisation as a reading aid is relevant for teaching reading strategies.
