简要总结
People's perceptual skills can significantly affect their abilities to make optimal decisions, judgments, and actions in real-world dynamic environments. Perceptual learning refers to training and experiences to induce improvements in the ability to make sense of what people see, hear, feel, taste or smell based on ambiguous sensory information. In this study, investigators hypothesise that there exist neural signatures that robustly encode the conscious visual perception of rotations of a cursor and the magnitudes of these rotations in a novel, rotation-based perceptual learning task. Investigators also hypothesise that online, instantaneous EEG-based feedback on subjects' visual perceptions of rotations with an EEG-based Brain Computer Interface (BCI) can foster perceptual learning much more effectively than behaviour perceptual training, especially in very small rotation magnitudes that represent extremely difficult perceptual tasks.

结局指标
主要结局
Change in correct answer rate of different rotation magnitudes across 5 intervention sessions
时间窗: Difference is measured every 24 hours, before versus after each intervention session
The correct answer rate per rotation magnitude reflects the improvements in perceptual skills across the two conditions. It measures the percentage of each rotation magnitude spotted correctly. The score is 0-100, and the higher the value, the better the outcome.
次要结局
- Change in neural correlates of conscious perception across 5 intervention sessions(Difference is measured every 24 hours, before versus after each intervention session)
