Often, we focus on how to improve the behavior of an individual, but there are many times in which teachers must figure out a way to improve the behavior of the entire class. In ABA, we might implement a group contingency, a strategy in which reinforcement for the whole group is based upon the behavior of one or more people within the group meeting a performance criterion (Cooper, Heron, & Heward, 2007).
Group contingencies can be especially beneficial for teachers because it may not always be possible to implement a contingency for an individual or there may be several students who need improvement with the same behavior. It’s also a useful strategy for individuals who respond well to peer influence. Furthermore, there are several studies that demonstrate the group contingencies can increase positive social interactions within a group.
Let’s look at examples of each type of contingency. In the first type, a dependent group contingency, reinforcement for all members of the group depends on the behavior of a single person within the group or a small group of people within the group. For example, you might say, “If Joseph remains in his seat for all of math, we will have five extra minutes of recess today.” This can be highly motivating for Joseph, because his peers will respond well to him if he earns them access to five more minutes of recess (leading some to call it the “hero procedure” because the individual is viewed so positively upon earning the reward.) It’s clear that if you have a student who is not motivated by social reinforcement from peers, this type of contingency would backfire. However, there is plenty of research that shows it’s benefits. (Allen, Gottselig, & Boylan, 1982; Gresham, 1983; Kerr & Nelson, 2002)
In the second type, an independent group contingency, criterion for accessing reinforcement is presented to everyone, but only the individuals who meet criterion earn the reinforcer. For example, you might say “If you remain in your seat for all of math class, you will earn five extra minutes of recess today.” In this contingency, every student who reaches criterion accesses the extra recess time, but those students who left their seat do not earn the extra five minutes. Another example might be, “Each person who turns in all homework earns two bonus points on their spelling test.” In this set up, the entire class is working towards a common goal, but the individuals who achieve the goal earn reinforcement no matter how their peers perform.
In the third type, an interdependent group contingency, reinforcement for all members of the group depends on the behavior of each member of the group meeting a performance criterion. Mayer, Sulzer-Azaroff, & Wallace put it very well when they wrote “Independent group contingencies involve treating the members of a group as if they were a single behaving entity. The behavior of the group is reinforced contingent on the collective achievement of its members” (2014). In many classrooms there some type of independent group contingency in place, such as earning behavior points per class period or keeping your name on the green light (with yellow and red lights indicating problematic behaviors.) It’s quite simple to add an interdependent group contingency to these systems already in place. For example, you might say, “If all students names are still on the green light at the end of math, everyone earns an extra five minutes of recess.” There is evidence that interdependent group contingencies promote cooperation within groups (Poplin & Skinner, 2003; Salend & Sonnenschein, 1989).
Group contingencies are an excellent tool for classroom teachers, as well as anyone else working to manage a group of individuals.

This leads to several considerations to take into account when toilet training boys. I agree with Weitzen that some of these issues arise from the simple fact that women are predominantly toilet training boys. However, it’s also possible that such issues arise from the fact that many boys are trained in early intervention or preschool years without consideration of the implications of those training techniques several years down the line, and without further intervention or training later in life. Either way, it’s important to recognize that training of life skills should be completed in such a way as to develop effective skills that are similar to those of the child’s same-age peers. To that end, here are two considerations:
In the study, there were three pairs of siblings. The ages of the children with autism ranged from 5 years old to 8 years old. The ages of the siblings ranged from 8 years old to 13 years old. The researchers trained each sibling of a child with autism how to teach basic skills, such as discriminating between different coins, identifying common objects, and spelling short words. As part of this training, the researchers showed videos of one-on-one sessions in which these skills were taught, utilizing techniques such as reinforcement, shaping, and chaining. What the researchers did next was the part that really stood out to me: they discussed with the siblings how to use these techniques in other environments. Finally, the researchers observed the sibling working with their brother/sister with autism and provided coaching on the techniques.
