Differences in the Ability to Spot Rare, Non-salient or Hidden Targets

This project is a review of literature on individual differences in ability to detect rare, hidden, or non-salient targets and a reanalysis of existing data to pull out the impact of individual differences. Studies include spotting unfamiliar faces, use of radar and x-ray technology to locate hidden, new or removed objects and the use of CCTV.

Research questions

  • How does human variability affect ability to search efficiently and effectively for rare or non-salient targets, or to detect rare or non-salient differences between objects?
  • What does the research literature tell us about how training might improve such search, and with whom it might be most effective?
