Study Summary

This trial will study the effects of serial dependencies on radiologists' ability to correctly detect and classify tumors in X-rays.

Who is the study for?

This trial is for individuals with normal or corrected-to-normal vision, such as those who wear glasses or contacts. It's designed to help radiologists improve their ability to detect and classify tumors in x-rays by understanding how previous images they've seen can affect their current work.Check my eligibility

What is being tested?

The study investigates how past visual experiences bias a radiologist's perception and decisions when examining sequential x-rays. The goal is to establish these biases, identify conditions that influence them, and develop strategies to mitigate their negative effects on tumor detection and classification.See study design

What are the potential side effects?

Since this trial involves no drugs but focuses on the psychophysics of visual perception, there are no traditional side effects associated with medication. However, participants may experience eye strain or fatigue from viewing multiple x-ray images.
