The behavioral urgency of objects approaching your avatar

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Visual Attention

Background:

• The behavioral-urgency hypothesis posits that dynamic visual cues signaling imminent action capture attention.
• Traditionally, this is demonstrated by looming objects threatening the observer directly.
• Humans can identify with external entities, like avatars, suggesting a potential extension of this hypothesis.

Purpose of the Study:

• To investigate if behavioral urgency, traditionally linked to self-preservation, extends to an external avatar in a controlled environment.
• To determine if visual stimuli indicating a collision course with an avatar capture attention and influence response times.

Main Methods:

• Participants controlled an avatar in a 2-D computer game, performing a visual search task based on target shape changes.
• A separate, irrelevant moving object was introduced, sometimes on a collision course with the avatar.
• Response times and accuracy were measured under different conditions of object movement relative to the avatar.

Main Results:

• Responses were significantly faster when the moving object was on a collision course with the avatar compared to when it moved away or passed by.
• Visual search efficiency improved when any target object moved, regardless of its trajectory relative to the avatar.
• Faster response times were often associated with an increase in errors, suggesting urgency impacts response processes.

Conclusions:

• The behavioral-urgency hypothesis can be generalized to include external entities with which an observer identifies, such as game avatars.
• The findings indicate that visual attention is captured by potential threats to identified external entities, influencing action and response.
• Urgency appears to modulate response execution more than initial perceptual selection.
