After meeting the inclusion and exclusion criteria of the study, they will be assigned by simple randomization method using a random number table into groups of study. N/A Healthy individuals. Intervention 1: Intervention group I: Visual attention-based neurofeedback with effective visual stimulus. With the aim of enhancing EEG Alpha power at Oz channel to improve memory, six 30 minutes training sessions over two weeks. The device FlexComp Infiniti (Thought Technology Ltd, Montreal, QC) with the software developed in this study will be used. Intervention 2: Control group I: Conventional neurofeedback without monitoring user's visual attention. With the aim of enhancing EEG Alpha power at Oz channel to improve memory, six 30 minutes training sessions over two weeks. The device FlexComp Infiniti (Thought Technology Ltd, Montreal, QC) with the software developed in this study will be used. Intervention 3: Intervention group II: Visual attention-based neurofeedback with attentional capture mechanism. With the aim of enhancing EEG Alpha power at Oz channel to improve memory, six 30 minutes training sessions over two weeks. The device FlexComp Infiniti (Thought Technology Ltd, Montreal, QC) with the software developed in this study will be used. Intervention 4: Control group II: Conventional neurofeedback by monitoring user's visual attention without attentional capture mechanism. With the aim of enhancing EEG Alpha power at Oz channel to improve memory, six 30 minutes training sessions over two weeks. The device FlexComp Infiniti (Thought Technology Ltd, Montreal, QC) with the software developed in this study will be used. Yes - There is a plan to make this available What will be shared: All participants' data, after anonymization, will be shared through local and international biosignal online databases.
