Can we hear morphological complexity before words are complex?

Area of Science:

• Psycholinguistics
• Phonetics
• Morphological processing

Background:

• Listeners can differentiate phonemically identical word onsets of monomorphemic words using acoustic cues.
• Previous research established acoustic cue utilization for monomorphemic word distinctions.

Purpose of the Study:

• Investigate if phonetic information distinguishes unsuffixed from suffixed multimorphemic words before phonemic differences emerge.
• Determine if listeners utilize subphonemic cues for morphological distinctions.

Main Methods:

• Four experiments were conducted.
• Utilized forced-choice identification and mouse-tracking tasks.
• Focused on subphonemic phonetic information, particularly duration.

Main Results:

• Listeners successfully distinguished between monomorphemic and multimorphemic words using only subphonemic information.
• Acoustic duration alone was sufficient for this discrimination.
• Listeners appear to apply an abstract rule linking word duration to morphological structure.

Conclusions:

• Listeners can process morphological structure using subphonemic phonetic cues, specifically duration.
• Findings support theories of morphological processing that incorporate phonetic information.
• The study highlights the role of abstract rules in language comprehension.
