Understanding Visual Errors in Teledermatology
This study is looking at how our brains process images one after another, and if seeing many images in a row can affect how accurately doctors identify skin conditions in teledermatology (remote skin care). The researchers are using a method called "psychophysics of sequential biases" to understand these visual errors. They want to see if these errors happen and how they might impact clinical judgments. The goal is to develop recommendations to improve the accuracy of remote skin care. You can join if you are 18 or older and have normal or corrected-to-normal vision. The study is currently unclear on its recruitment status.
- Study design
- This is an interventional study that plans to enroll 10,120 participants. It involves groups of both dermatologists and untrained observers.
- What's involved
- You would participate in a psychophysical experiment for 30-60 minutes. During this time, you would look at images of skin lesions and be asked to classify or identify features.
- Compensation
- Not stated in the trial record.
- Follow-up
- Not specified.

What this trial measures
- Serial Dependence Assessment using psychophysical proceduresEach participant is tested for 30-60 minutes in a psychophysical experiment.
This is a medical image perception experiment using psychophysical methods, including continuous report match-to-sample and method-of-constant stimuli designs. Human observers, including clinicians and untrained observers, are recruited to classify or discriminate medical images. Each observer participates in approximately 300 trials in a session. On each trial, observers view a medical image on a computer monitor and are asked to make either a match-to-sample or a two-alternative forced choice decisions about the image. Observer responses on each trial are classified in terms of their accuracy. Outcome measures include hit rate, false alarm rate, sensitivity, selectivity, d', and criterion. Changes in these metrics from trial-to-trial throughout the course of the experiment are quantified as metrics of sequential biases that might be present in observer judgments.
