Abstract
Shaping what we see: pinning down the influence of value on perceptual judgements
Highlights
Despite a commonsense view that vision provides a veridical window onto the world around us, a growing body of scientific evidence suggests a more complicated account
Since the application of signal detection theory (SDT) to psychology in the 1950s, it has been clear that categorical decisions, including simple sensory judgements, necessitate decision thresholds (Green and Swets, 1966)
The relatively simple solution provided by SDT is that a decision criterion is applied to the fixed, unchanging sensory evidence on any given trial
Summary
Despite a commonsense view that vision provides a veridical window onto the world around us, a growing body of scientific evidence suggests a more complicated account. The relatively simple solution provided by SDT is that a decision criterion is applied to the fixed, unchanging sensory evidence on any given trial.
