Segmented binaural presentation as a means to examine lexical substructure
We present an auditory presentation technique called segmented binaural presentation. The technique builds on the dichotic listening paradigm (Shankweiler & Studdert-Kennedy, 1967; Studdert-Kennedy & Shankweiler, 1970) and segmented lexical presentation (Libben, 2003; Betram, Kuperman, Baayen, & Hyönä, 2011). The technique allows the first part of a word to be presented to one ear and the second part of the word to be presented to the other ear. The experimenter may thus manipulate whether a stimulus is segmented in this binaural manner and, if it is segmented, the location of the binaural segmentation within the word. We discuss how the technique may be implemented on the Macintosh platform, using PsyScope and freely available software for audio file creation. We also report on a test implementation of the technique using suffixed and compound English words in a lexical decision task. Results suggest that the technique differentiates between segmentation that occurs within and between compound constituents.
