Based on the following article,

LaRue, R., Steward, V., Piazza, C., Volkert, V., Patel, M., Zeleny, J. (2011). Escape as reinforcement and escape extinction in the treatment of feeding problems. Journal of Applied Behavior Analysis, 44, 719 - 735

Please outline the 4 procedures using the charts below:

Escape for Inappropriate Behavior

Antecedent	Behavior	Consequence

Escape for Inappropriate Behavior & Mouth Clean (note: there were 2 contingencies available here)

Antecedent	Behavior	Consequence

Escape Extinction (note: there were 2 contingencies available here)

Antecedent	Behavior	Consequence

Escape Extinction plus Escape for Mouth Clean (note: there were 2 contingencies available here)

Antecedent	Behavior	Consequence

Why do the authors say that although they did not convincingly show that escape for clean mouth served as a maintaining reinforcer for the appropriate behavior, escape extinction in feeding disorders is important (Hint: look on page 733 - 734)?
