"The construct of behavioral or response inhibition comprises three interrelated processes: 1. Inhibiting the initial prepotent response to an event. 2. Stopping an ongoing response or response pattern, thereby permitting a delay in the decision to respond or continue responding. 3. Protecting this period of delay and the self-directed responses that occur within it from disruption by competing events and responses (interference control)."
"Inhibition creates the delay in responding, protects the self-directed (often covert) actions to the self that are initiated within that delay, and protects the eventual execution of the goal-directed responses generated from those self-directed actions from disruption by extraneous sources of interference."
"Response inhibition is critical not just to delaying the prepotent response to an event but also to the conversion of public into private (covert) forms of self-directed behavior that are occurring within that delay (the executive functions). This is done so that the individual can engage in response simulations, testing out response options before one is selected for performance. Such self-directed actions may be ‘‘privatized’’ by humans so that others cannot easily discern their occurrence or content."
