People showed stronger steady-state visually evoked potentials (SSVEP) over the visual stimuli that were under their control, compared with the stimuli that were not under control.

Attention can be attracted to an object that is under one's control when people do not have much control over the external world. On the other hand, when people have already acquired a high level of control, a small loss of control greatly attracts attention.

The establishment/detection of control elicited a large P300, and is associated with the decrease of the power of mu-rhythm.

Moving a virtual rubber hand with a goal (i.e., touching a flying object) enhanced the rubber hand illusion by showing larger proprioceptiive drift, compared with the condition moving the hand forward and back upon a cue.

A computer assistance improved task performance by ignoring erroneous commands. In such condition, people felt strongger sense of agency, even though they had actually less control over the moving stimulus, compared with the condition when they had full control over it. This result indicated a large weight of high level processes underlying the sense of agency.

In this project, we developed a system that effciently abstracts skills from professional nurses' bed caring movements, digitalizes and saves the skills in an online database for e-Learning.
People were able to correctly recognize their friend's real face, but tended to choose a photo of their own face with slightly larger eyes and smaller mouth. Such bias towards slightly more beautiful self-face in memory may due to both perceptual factors (e.g., the observing distance of self-face) and cultural factors (e.g., selfie culture).

People with good sense of direction use all verbal, visual and spatial working memory to learn the space, while people with poor sense of direction tend to rely on language.
