Abstract
Purpose:To measure and compare P300 latency and amplitude in normal hearing children at different age groups.
Methods: A cross-sectional study with 96 children aged between 8 and 11 years and 11 months, equally divided into four age-based groups. P300 assessment was conducted using the Masbe ATC Plus equipment (Contronic®), with 1000 Hz and 2000 Hz stimuli, at an 80/20% probability.
Results: The mean P300 latency and amplitude values were 339.57 ± 41.03 and 18.22 ± 7.59 in G1, 327.94 ± 37.29 and 16.32 ± 7.01 in G2, 321.05 ± 31.84 and 15.86 ± 5.08 in G3, and 310.76 ± 28.99 and 11.24 ± 3.12 in G4, respectively.
Conclusion: All children presented P300. There were no differences regarding P300 latencies and amplitudes when comparing different age groups in this study.
