Pseudowords and Word Recognition: An ERP Study
Author Information
Author(s): Claudia Friedrich, Carsten Eulitz, Aditi Lahiri
Primary Institution: University of Konstanz
Hypothesis
Do pseudowords that differ in a single acoustic feature disrupt word recognition differently based on their phonological structure?
Conclusion
The study found that lexical representations of words with medial coronal consonants are activated by their corresponding non-coronal pseudowords more quickly than by coronal pseudowords.
Supporting Evidence
- N400 amplitudes for pseudowords were enhanced compared to words.
- The N400 pseudoword effect starts earlier for coronal than for non-coronal pseudoword variants.
- Non-coronal variants are accepted as words longer than the coronal variants.
- Behavioral results showed significant differences in reaction times and error rates between words and pseudowords.
Takeaway
This study shows that some made-up words (pseudowords) can trick our brains into thinking they are real words, especially if they sound similar to real words.
Methodology
Event-related potentials (ERPs) were recorded during a lexical decision task focusing on medial consonants in German disyllabic words.
Potential Biases
Potential bias due to the small sample size and the specific demographic of participants.
Limitations
The study only included right-handed native German speakers, which may limit the generalizability of the findings.
Participant Demographics
Sixteen undergraduate students (8 females, 8 males) from the University of Konstanz, all native German speakers.
