Sensitivity

Sensitivity may refer to:

Science and technology

Sensitivity (physiology), the ability of an organism or organ to respond to external stimuli
- Sensory processing sensitivity, a personality trait in humans
Sensitivity and specificity, statistical measures of the performance of binary classification tests
Allergic sensitivity, the strength of a reaction to an allergen
The inverse of resistance (ecology), the ability of populations to remain stable when subject to disturbance

Sensitivity (electronics). Two contrasting definitions of sensitivity are used in the field of electronic sensors and instruments
- Sensitivity first definition: the ratio between output and input signal, or the slope of the output versus input response curve of a transducer, microphone or sensor
- Sensitivity second definition: the minimum magnitude of input signal required to produce an output signal with a specified signal-to-noise ratio of an instrument or sensor

Sensitivity (control systems), variations in process dynamics and control systems
Sensitivity analysis, apportionment of the uncertainty in the output of a mathematical model among its inputs
Sensitivity and specificity, statistical measures of the performance of binary classification tests

Sensitivity (explosives), the degree to which an explosive can be initiated by impact, heat or friction
Film speed, photographic film's sensitivity to light

"Sensitivity" (Shapeshifters song), the fourth single from music group Shapeshifters
"Sensitivity" (song), a song by rhythm and blues singer Ralph Tresvant
