The influence of pitch-by-pitch feedback on neural activity and pitch perception in baseball

This study was designed to examine the influence of performance feedback on task performance and neural activity in expert and novice baseball players. Participants completed a video task to determine whether thrown pitches were balls or strikes while their neural activity was recorded. After each pitch, participants were given feedback on the accuracy of their choice. Results indicated that college players exhibited larger frontocentral positivity amplitudes compared with novices, regardless of feedback type. Furthermore, results showed that the feedback-related negativity was related to response accuracy following incorrect feedback for college players, with larger feedback-related negativity amplitude associated with greater response accuracy. This relationship is independent of any relations between overall task accuracy and either feedback-related negativity amplitude or response accuracy following incorrect feedback. These results indicate that the nature of neural activity during pitch feedback for college baseball players can inform and influence participants' subsequent pitch-location performance.
