Hypothesis
How do speech and non-speech audio-visual illusions develop across childhood and adolescence?
Conclusion
The study found that while speech audio-visual illusions develop with age, non-speech illusions remain consistent across different age groups.
Supporting Evidence
- Performance on speech illusions improved with age, while non-speech illusions showed no age-related differences.
- The McGurk effect was significantly weaker in younger children compared to older groups.
- Participants' lip-reading abilities did not significantly differ across age groups.
Takeaway
Kids see and hear things differently as they grow up; they get better at understanding speech illusions but not at non-speech ones.
Methodology
Participants aged 5 to 19 were tested on various audio-visual illusions, including the McGurk effect, Illusory Flash effect, and Fusion effect.
Limitations
The study excluded individuals with neurodevelopmental disorders, which may limit the generalizability of the findings.
Participant Demographics
38 French-speaking subjects (15 males, 23 females) aged 5 to 19 years.
