Paradigms

Language Production

Linguistic corpus-based analyses of language output Naming

Language Comprehension

Ability to answer questions about the content of sentences and discourse Ability to distinguish between coherent and incoherent sentences and discourse Detection and classification of semantic relationships between words Listening and reading times to critical words and regions in linguistic input Patterns of eye movements (in eye tracking paradigms) or motor movements (in mouse tracking paradigms) to critical words and regions in linguistic input Patterns of eye movements to non-verbal visual stimuli during spoken language comprehension (the visual world paradigm)

Experimental Manipulations

Manipulations of different types of coherence and cohesion between clauses in discourse Manipulations of different types of relationships between individual words in priming paradigms Manipulations of predictability and acceptability, at different levels of representation, in a linguistic input Manipulations of relationships between language and non-verbal behaviors
