I will present the poster “The Psychology and Neuroscience of Confidence in Memory and Perception” at Psychonomic Society’s annual convention. This poster (2427) is based on an expansion of my qualifying paper, and will be co-authored between myself and Dr. John T. Wixted.

This year’s meeting will take place on November 4-7. I will be available for live discussion within the meeting platform on November 6th, 12-1pm Central Time. Or, as always, contact me with any questions.

Abstract:

The solution to real-world problems often requires a deep, basic-science understanding of the problem at hand. Confidence and decision time are issues that matter in the real-world and have been intensively investigated in the past 20 years in both psychological science and neuroscience. In cognitive psychology, confidence is usually conceptualized in terms of signal detection theory while speeded decision-making is conceptualized in terms of evidence accumulation modeling. However, no singular model of confidence for a perceptual decision dominates. In mathematical psychology, accounts of speeded decision-making in terms of a balance-of-evidence decision variable has gained currency in recent years. In neuroscience, the field tends to approach evidence accumulation and confidence in relation to lateral intraparietal cortex (the role of which is debated) and reaction time, with some research indicating a balance-of-evidence decision variable. A review of these largely independent lines of research suggests a potentially fruitful way to naturally integrate signal detection theory and evidence accumulation models in a way that comports with the relevant neuroscience evidence.

Update: The abstract number was previously 5117. Renumbering occurred when this year’s annual convention moved from a hybrid format to strictly online. You can view a PDF of the poster here.
