Melina A. Kunar; Olugbemi Moronfolu; Rupam Jagota – Cognitive Research: Principles and Implications, 2025
Previous research has found that people miss a large proportion of targets that appear rarely. This Low Prevalence (LP) Effect has implications for applied tasks such as mammography. The current study investigated whether the LP effect can be reduced by feedback and internal incentives, which affect motivation. Experiment 1 found that miss errors…

The Optimal Use of Computer Aided Detection to Find Low Prevalence Cancers
Peer reviewed Peer reviewed

Kunar, Melina A. – Cognitive Research: Principles and Implications, 2022
People miss a high proportion of targets that only appear rarely. This low prevalence (LP) effect has implications for applied search tasks such as the clinical reading of mammograms. Computer aided detection (CAD) has been used to help radiologists search mammograms by highlighting areas likely to contain a cancer. Previous research has found a…
