Visual, auditory, kinesthetic, irrelevant imagery and corresponding eeg

The purpose of this study was to investigate whether different EEG responses occur in specific locations of the brain with visual, auditory, kinesthetic and irrelevant imagery during preperformance routines. Seventy university students (male=30, female=40), with a mean age of 20.1 (ages ranged from 19-23) participated in this study. Subjects were randomly assigned to one of five conditions: 1. visual imagery, 2. auditory imagery, 3. kinesthetic imagery, 4. irrelevant imagery and 5. a control condition. EEG data were collected with a BIOPAC system using a red E1-M electro-cap of medium size. The recordings of EEG alpha waves were made at the scalp locations occipital (O1), central (C3), parietal (P3) and temporal (T3) while subjects were performing their respective imagery. One-way MANOVA was conducted for frequencies on alpha waves of the O1, P3, C3 and T3. The present results show that during visual, auditory, kinesthetic, and irrelevant imagery magnitudes of the alpha in the occipital, central, parietal and temporal areas did not differ from any of the other groups' conditions.
