Mr. Shoney had inadvertently shaped intense and long-lasting tantrums in his young son, Harvey. Mr. Shoney is divorced and working out of his home. When Harvey engaged in tantrum behaviour, Mr. Shoney tried to ignore it and continue working, but about half of the time he eventually gave Harvey what he wanted. Often, Harvey engaged in the tantrum behaviour for 20 to 30 minutes before his dad stopped working and gave him what he wanted. Harvey's tantrums consisted of whining, crying, and pleading for what he wanted (e.g., ice cream, playing a game, going to the park). Describe how Mr. Shoney should implement extinction to eliminate Harvey's tantrum behaviour.
