Perceptual decision research, explained
4 open-access perceptual decision studies, each with a flashcard deck and a quiz.
- Can brain scans predict if a person is feeling pain?
By analyzing patterns across multiple brain regions simultaneously, researchers could predict whether a person perceived a subtle stimulus as painful, even when the stimulus intensity remained constant.
- How does the brain switch between different ways of seeing?
Spontaneous flips in how we perceive ambiguous images are driven by bidirectional communication between visual and parietal brain regions, and the strength of bottom-up signals determines how long each view lasts.
- How the Brain Tracks Choices When Things Are Unclear
A brain wave signal tracks how uncertain we are during decisions, regardless of what we are looking at.
- Tracking Decision Making in the Brain Using fMRI
While many brain areas collect sensory evidence, only a specific network in the frontal cortex marks the exact moment a decision is made.
