Social contagion of challenge-seeking behavior.

Despite having little economic utility, people are sometimes motivated to seek challenges (i.e., proactively choosing to work on a more difficult task than an easier one).

Thinking about thinking: People underestimate how enjoyable and engaging just waiting is.

The ability to engage in internal thoughts without external stimulation is a unique characteristic in humans. The current research tested the hypothesis that people metacognitively underestimate their capability to enjoy this process of "just thinking." Participants (university students; total N = 259) were asked to sit and wait in a quiet room without doing anything.

Temporal ventriloquism along the path of apparent motion: speed perception under different spatial grouping principles.

The coordination of intramodal perceptual grouping and crossmodal interactions plays a critical role in constructing coherent multisensory percepts. However, the basic principles underlying such coordinating mechanisms still remain unclear. By taking advantage of an illusion called temporal ventriloquism and its influences on perceived speed, we investigated how audiovisual interactions in time are modulated by the spatial grouping principles of vision.
