Probabilistic visual attentional guidance triggers "feature avoidance" response errors.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Spatial attention influences perception and memory at attended and unattended locations.
• Attentional manipulation (top-down cues, bottom-up capture) causes specific feature errors.
• The impact of experience-driven and probabilistic attentional guidance on feature errors is less understood.

Purpose of the Study:

• To investigate if experience-driven and probabilistic attentional guidance produce similar feature errors.
• To examine the nature of errors when attention is guided probabilistically to invalid locations.
• To understand the strategic mechanisms underlying attentional guidance and feature perception.

Main Methods:

• Conducted pre-registered experiments using learned spatial probability or probabilistic pre-cues.
• Participants reported the color of one of four simultaneous stimuli via continuous response.
• Manipulated attentional guidance to valid and invalid locations using probabilistic cues.

Main Results:

• When attention was cued to an invalid location, participants were less likely to report the target color.
• Strikingly, errors clustered around a nontarget color opposite the invalidly cued nontarget color.
• This
• feature avoidance
• occurred with both experience-driven and top-down probabilistic cues.

Conclusions:

• Probabilistic attentional guidance, including experience-driven forms, can lead to "feature avoidance" errors.
• This strategic behavior may arise when limited information is available outside the focus of attention.
• Different types of attentional guidance can differentially impact feature perception and memory reports.
