Understanding Your Metrics
Hit Rate
The percentage of correct responses to Go trials. Reflects attention and ability to respond to target stimuli. Higher hit rates indicate better sustained attention.
False Alarm Rate
The percentage of incorrect responses to No-Go trials (pressing when you should have withheld). This is the key measure of impulse control - lower rates indicate stronger inhibitory control.
Inhibitory Control
The ability to suppress inappropriate responses, a core component of executive function. The Go/No-Go test measures this through the false alarm rate.
Reaction Time
The time interval (in milliseconds) between stimulus onset and response. Affected by attention, fatigue, and cognitive processing speed.
Sensitivity (d')
A core Signal Detection Theory metric measuring the ability to discriminate Go (signal) from No-Go (noise) stimuli. Higher d' indicates better discrimination. Healthy adult range: 1.5-3.0, average ~2.2.
Overall Score
A composite score based on hit rate (30% weight), false alarm rate (50% weight), and reaction time (20% weight). False alarm rate has the highest weight as inhibitory control is the primary goal of the Go/No-Go test.
