Abstract A novel paradigm of study of spatial selective attention based on EEG signal response is presented in this paper. Steady-state visual evoked potential (SSVEP) is adopted to strengthen the response of week EEG signals. LED flickering stimuli replace of the conventional LCD display screen increases the stimulation and its flickering frequency. Combing SSVEP extracting, joint features forming, and SVM classification techniques give the integral procedure of attention pattern recognizing. This paradigm will reach the excellent performance of spatial selective attention. The experiment results prove that the rate of correct recognizing is almost one hundred percent.
