Summary

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.

Interventions

Type	Name	Description
DEVICE	EEG-based perceptual training	Electroencephalography (EEG) signals will be recorded from subjects as they perform rotation-based perceptual tasks. The neural correlates of conscious perception of rotations will be processed and decoded in real-time using machine learning algorithms to provide feedback. Subjects are instructed to assume a mental state/find a strategy to maximise the accuracy of feedback. In total, each subject will complete 5 sessions of perceptual training with this intervention.
DEVICE	Behavior based perceptual training	Subjects complete the rotation-based perceptual tasks, and ground truth visual feedback is provided indicating whether subjects have spotted the rotations correctly. Subjects are instructed to spot as many rotation as possible to maximise the accuracy of feedback. In total, each subject will complete 5 sessions of perceptual training with this intervention.
