3.3.11

Percept

Measurable response of any wetware component or combination of wetware components to a stimulus.

 

3.3.12

Perception

The process of coding, organizing and otherwise attending to percepts by wetware.

 

3.3.13

Threshold

The point at which the quantity of a stimulus induces a qualitative change in perception. At a threshold, the stimulus becomes a percept.

note: Any given wetware modality can support multiple thresholds according to age, culture and other variables.

 

 

3.3.14

Absolute threshold

indicates the quantity at which a stimulus can become a percept.

 

3.3.15

Difference Threshold

The quantity at which two different stimuli can be discriminated by nerve endings (sensory and/or motor) into distinct percepts.

 

3.3.16

Suprathreshold

The quantity beyond which a stimulus can no longer become a percept.

 

3.3.17

Below Threshold

Quantity of stimulus is insufficient to becoming a percept.

 

3.3.18

Maximal Threshold

Quantity of stimulus beyond which safe telebiometric browsing cannot be assured. Expressed in SI units.

note: these definitions help bridge the set of threshold concepts of neuroscientists and the threshold concepts of standardization.
