shortly after, but they are frantic from their 5-minute search and accidentally scare him from going outside. In this non-example, learning to open doors that lead outside resulted in consequences that did not directly benefit the child and maybe decrease important skills related to exploration and search. In this case, no new reinforcers were contacted and learning to open the backyard door (that has a special latch) was effectively a waste of time because the child's parents don't usually approve being alone in the backyard.

of the stakeholder resulting from a cusp in the learner. The initial and gradually more complex behaviors that constituted the entry point for an important behavior change that, once initiated, so profoundly alters, displaces, or transforms one's behavioral repertoire that it renders preexisting behavioral repertoires obsolete. A behavioral cusp is an important behavior change that alters the probability of the learner's future repertoires and interactions with stakeholders' repertoires.

of instruction and, as a result, they regulate boundary of what the learner learns (e.g., school curriculum). Practitioners are confident that their cusp will lead to the desired behavior and open the door to new environments. New environments must contain some of the stakeholders' preferences and reinforcers to create lasting

Effect on others comes from the learner's behavior affecting the stakeholders who control reinforcers and punishers in a specific environment. It is important to identify these stakeholders' motivations and reinforcers in selecting potential cusps. Effect refers to the changes in values and behaviors

New environments are geographical and/or virtual areas of potential change (receiving environments). New environments regulate, maintain, and set the micro-cultural boundaries for reinforcers (and punishers), and their antecedents. They include tools and stakeholders controlling the pace and content

change that brings an organism's behavior into contact with new contingencies that have far-reaching consequences. A behavioral cusp is a special type of behavior change because it provides the learner with opportunities to access new reinforcers, new contingencies, new environments, new related

Generativeness describes the ability of the receiving environment to regulate novel responses, functions, values or response products derived from the original cusp response. For a behavior, it is the ability to recombine or merge into more complex units, or the ability to contact environments.

A child who learns to open a door may access the swing for the first time and learns to use the swing. Here, the new skill (swinging motion is the reinforcer) may lead to more complex and social activities such as (1) turn taking, (2) asking someone to share the swing, (3) taking turns pushing

English phonemes into 50,000 words by recombining the individual sounds he has learned to read. The generative index for this act of learning the basic English phonemes is approximately 10,000 (where one new behavior results in a potential 10,000 applications).

The behavioral cusp has implications for the selection and sequencing of skills during the life span. While milestones are mainly concerned with the chronology of behaviors, the concept of behavioral cusp is concerned with the fitness of the behavior within a context or a

New reinforcers are accessible and enrich the perspective of the learner. Additionally these reinforcers may lead to an increase in the variety of behaviors. If the reinforcers are promoting health and social behaviors, they will lead to an improved quality of life.

Behavior competition is the ability of cusp behaviors to displace previously established behaviors on a continuum of intensity and rate, across repertoires, and environments. Competing archaic behaviors occur on a corresponding continuum of severity.
