Answer:
The two characteristics of motivating operations are the value-altering effect, which alters the reinforcing effectiveness of a stimulus, and the behavior-altering effect, which alters the current frequency of all behavior associated with that stimulus.
Explanation:
Motivating operations are environmental variables that explain the variations which are there in the effects in the result of behavior. It was introduced by 'Jack Michael'.
It changes the effectiveness of some stimulus or object that reinforces (value-altering effect), and changes the current frequency of behavior that is associated with that stimulus (behavior-altering effect).
Motivating operations are also divided as Establishing Operation which increases the current effectiveness and Abolishing Operation which decreases the current effectiveness of some stimulus, object, or event as reinforcement.
