Language universals and misidentification: a two-way street

Area of Science:

• Psycholinguistics
• Phonology
• Speech Perception

Background:

• Certain phonological structures are rare in languages and difficult for humans to identify.
• It's debated whether this difficulty stems from innate language rules or phonetic processing limitations.

Purpose of the Study:

• To investigate whether misidentifications of ill-formed phonological structures result from active grammatical recoding or phonetic encoding difficulties.
• To examine the impact of task-based attention (global phonological vs. local phonetic) on the perception of unattested onset clusters.

Main Methods:

• Five experiments were conducted using tasks that directed attention towards either global phonological structure (syllable counting) or local phonetic detail (segment detection).
• Participants identified onset clusters unattested in their native language.

Main Results:

• When focusing on global phonological structure, participants misidentified ill-formed onset clusters more frequently than well-formed ones.
• When focusing on local phonetic detail, participants accurately identified both ill-formed and well-formed onset clusters, showing sensitivity to phonetic cues.

Conclusions:

• Misidentification of ill-formed phonological structures is driven by active recoding influenced by linguistic knowledge, rather than passive phonetic perception failures.
• The relationship between language and perceptual misidentification is bidirectional, with perception potentially shaping linguistic knowledge.
