Extinction

     The goal of extinction was to extinguish Ms. Jingles's behavior of pressing the bar. Extinction took us two days. During the first five minutes of extinction on the first day, Ms. Jingles was noticeably frustrated and displayed an extinction burst, pressing the bar 129 times in this short period. The number of presses per five minute period decreased during the first day of extinction, but during the first five minutes of the second day we noticed she had some spontaneous recovery, pressing the bar 76 times.

This is a table showing a breakdown of the number of presses for extinction.
