Summary
This study explored phonological processing in adults with cochlear implants. Results suggest that cochlear implants can facilitate phonological activation, even from visual cues.
Area of Science:
- Neuroscience
- Audiology
- Linguistics
Background:
- Investigating phonological representations in postlingually deafened adults using cochlear implants (CIs).
- Prior normal language development in subjects before acquiring deafness.
- Assessing phonological representations through CI input.
Purpose of the Study:
- To compare auditory-only priming with visual-auditory cross-modal priming in CI users.
- To determine if phonological representations are activated via CI input.
- To explore the role of lexical phonological representations in priming effects.
Main Methods:
- Two postlingually deafened adults participated in lexical decision experiments.
- Utilized word primes with phonologically related and unrelated word/pseudoword targets.
- Compared unimodal (auditory) and cross-modal (visual-auditory) priming conditions.
Main Results:
- Varied priming effects observed between the two patients.
- Patient 1: Priming for word targets in the unimodal condition only.
- Patient 2: Priming for word targets and pseudoword interference in the cross-modal condition; no unimodal effect.
Conclusions:
- Lexical phonological representations appear to contribute to priming effects in CI users.
- Phonological word forms can be activated by visual stimuli processed through CIs.
- Suggests potential for visual-to-auditory phonological processing via CIs.
