Self-Control

A hypothetical construct referring to "will power" that involves two responses: (1) the target response to be controlled (e.g., eating, completing math problems, or throwing temper tantrums) and (2) the response emitted in order to control the rate of the target behavior (e.g., recording everything eaten, the number of math problems completed correctly, or the number of temper tantrums thrown during the day). Self-control is assumed to reflect an internal process that occurs without the presence of immediate and obvious external contingencies.

Reactivity

A phenomenon that results from the act of self-monitoring. Reactivity is said to occur when a behavior being monitored changes as a result of observing and recording it. Also known as the reactive effect.

Self-Monitoring

The process of observing and recording one's own behaviors, thoughts, or emotions to increase self-awareness or modify behavior.
