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). The present study investigated whether just observing others' challenge-seeking behaviors could motivate people to seek more challenging tasks-the social contagion effect of challenge-seeking. The participants were presented with pairs of options, each associated with a math word problem of a certain difficulty level. We examined whether the participants' preference for a more challenging (i.e., more difficult) option changes after observing the decisions of others who hold a challenge-seeking or a challenge-avoiding attitude. Five experiments consistently showed that, while the participants generally avoided challenging word problems, observing challenge-seeking in others increased the probability of participants choosing more challenging options. These results indicate that our motivation to seek challenges may be instilled, in part, through social processes. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

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. Across six experiments, we consistently found that participants' predicted enjoyment and engagement for the waiting task were significantly less than what they actually experienced. This underappreciation of just thinking also led participants to proactively avoid the waiting task in favor of an alternative task (i.e., Internet news checking), despite their experiences not being statistically different. These results suggest an inherent difficulty in accurately appreciating how engaging just thinking can be, and could explain why people prefer keeping themselves busy, rather than taking a moment for reflection and imagination in our daily life.

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. In our experiments, we manipulated the spatial grouping principles of proximity, uniform connectedness, and similarity/common fate in apparent motion displays. Observers compared the speed of apparent motions across different sound timing conditions. Our results revealed that the effects of sound timing (i.e., temporal ventriloquism effects) on perceived speed also existed in visual displays containing more than one object and were modulated by different spatial grouping principles. In particular, uniform connectedness was found to modulate these audiovisual interactions in time. The effect of sound timing on perceived speed was smaller when horizontal connecting bars were introduced along the path of apparent motion. When the objects in each apparent motion frame were not connected or connected with vertical bars, the sound timing was more influential compared to the horizontal bar conditions. Overall, our findings here suggest that the effects of sound timing on perceived speed exist in different spatial configurations and can be modulated by certain intramodal spatial grouping principles such as uniform connectedness.
