Covert attention leads to fast and accurate decision-making

Area of Science:

• Cognitive Psychology
• Decision Science
• Neuroscience

Background:

• Decision-makers often face information overload, exceeding their capacity for direct visual attention.
• Traditional theories posit a speed-accuracy trade-off due to sequential information processing.
• Overt attention (direct gaze) is assumed to be the primary mechanism for information gathering.

Purpose of the Study:

• To investigate the role of covert attention in decision-making under information overload.
• To determine if covert attention can mitigate the negative effects of information overload on decision speed and accuracy.
• To explore factors influencing the use of covert attention during choice evaluation.

Main Methods:

• Reanalysis of data from five previously published studies on decision-making.
• Analysis of participants' attentional strategies, including overt and covert attention.
• Examination of the relationship between covert attention use, information salience, and decision outcomes.

Main Results:

• Participants frequently employed covert attention, evaluating information without direct gaze.
• Covert attention was more prevalent when visual information was large or salient.
• The use of covert attention correlated with faster decision times, suggesting simultaneous information processing.
• Covert attention facilitated maintaining high decision accuracy despite increased information.

Conclusions:

• Covert attention is a crucial, often uninstructed, mechanism in decision-making, especially under information overload.
• Harnessing covert attention allows decision-makers to increase speed without sacrificing accuracy.
• Understanding and leveraging covert attention can enhance consumer choices, particularly for healthy and sustainable products.
