Definitions:

Habituation

The process by which an organism reduces its response to a repeated stimulus over time, not due to fatigue or sensory adaptation.

Short-Term Memory

The ability to keep a limited amount of data in a state of readiness and easy access for a brief duration.

Dishabituation

The process of responding to an old stimulus as if it were new again, following the presentation of a new stimulus that interrupts the process of habituation.

Habituate

To become accustomed to something through repeated exposure, often leading to decreased responsiveness.
