| Abstract |
| This study aims to analyze using RQA(Recurrence Quantification Analysis) about difference of electroencephalogram between inattention and attention among nonlinear methods for school age children who need attention. The experiments were conducted by 21 healthy subjects(12 males and 9 females). Inattention state is 500msec before the beginning of the auditory stimuli, attention state is 500msec after the beginning of auditory stimuli. The results of RQA parameters are greater in attention state than inattention state. It showed a statistically difference(p < 0.05). According to two states, auditory evoked potentials are displayed RP and CRP in diagram form to confirm nonlinear characteristics and The brain dynamics in the attention is more complex than the inattention. It is feasible that the RQA can be useful for the analysis of complex brain dynamics associated during auditory attention al task. |
