Intermittent positive reinforcement

Intermittent positive reinforcement is the concept BB Easton uses to make sense of Ronald McKnight’s persistence after their relationship ended. In her account, he kept calling while she answered only unpredictably—sometimes no more than twice a year. That uneven pattern becomes more than a description of an ex’s phone habits: it supplies a psychological explanation for a relationship she had struggled, unsuccessfully, to leave behind.

Definition and Discovery

The concept enters the story through a behavioral-psychology class. As a sophomore in college, BB Easton hears a graduate student explain that a behavior may persist more reliably when it is rewarded at random intervals than when it is rewarded every time. She recognizes Ronald McKnight’s calls in the explanation and understands her occasional answers as the intermittent reward that has helped keep them coming.

The insight arrives three years after the breakup, which had taken place during her junior year of high school. By then, she had been trying, and failing, to avoid him. The delay matters: the term does not initiate a new strategy so much as rename a familiar pattern. What she had experienced as an ex who would not stop calling becomes, in retrospect, a cycle in which her own sporadic response may help sustain the behavior.

Her recognition is immediate and public. When the instructor asks for an example, BB Easton thrusts her cell phone into the air, startled by the fit between the classroom principle and her private history. The gesture gives the idea a concrete object: the phone is not simply how Ronald McKnight reaches her, but evidence through which she can reinterpret the pattern.

The Call-and-Answer Pattern

Ronald McKnight’s calls continue through changes in circumstance. He keeps contacting her after ugly breakups; when he loses or destroys his phone, becomes drunk, or goes a long time without speaking to her, he still remembers her number. The account emphasizes the recurrence rather than describing the content of each call: the persistent fact is that he calls again.

Over time, the calls change in character. They recede from what BB Easton describes as traumatizing-stalker levels to the more ordinary pattern of late-night calls from a drunk former boyfriend. But the reduced intensity does not mean the connection has disappeared. She says that, whether the relationship was good, bad, or ugly, she answered no more than twice a year. Her comparison to taking a potent drug every six months conveys both restraint and continued susceptibility: she knows that contact can pull her back into a bond she is trying to escape.

The schedule is the key detail. She does not answer every call, nor does she sever contact completely. Her occasional pickup becomes the irregular reward in the pattern she identifies. The book presents this as her retrospective application of a concept, not as a deliberate plan to influence Ronald McKnight. It also does not detail what happens in each conversation, so the significance lies in the recurring contingency she recognizes—calls continue, and sometimes she answers—not in any particular exchange.

Relationship History and Emotional Force

The concept gains force from the earlier relationship’s combination of attraction and fear. At Peggy's house, a chase that begins as a tickle fight escalates into Ronald McKnight repeatedly recapturing and pinning BB Easton. She interprets their dynamic as predator and prey, fears what may happen, and nevertheless experiences the tenderness of his first kiss as an intense shock. In the aftermath, she understands him as being in love with her while also fearing that she may never escape him. These details establish why later contact is not emotionally neutral, though the book does not claim that the early encounter itself explains the call pattern.

The same ambivalence appears in her account of answering. Ronald McKnight is not simply a figure from a finished relationship: she describes him as a drug potent enough that even infrequent contact risks drawing her back. The metaphor makes the intermittent pattern personal. Each answer is limited, but the possibility of renewed involvement remains powerful enough that she deliberately restricts how often she responds.

Meaning and Limits

Intermittent positive reinforcement provides BB Easton with a concise behavioral explanation for the endurance of the calls. It shifts attention from Ronald McKnight’s persistence alone to the interaction between his repeated attempts and her occasional replies. The concept also turns a painful personal history into an example she can recognize and offer in a psychology classroom, making insight arrive through a collision between lived experience and academic language.

The explanation remains bounded by her own account. It identifies a pattern and its likely reinforcing effect; it does not establish that either person consciously engineered that pattern, or settle every reason the relationship continued to matter. Its significance is the change in interpretation: what once seemed like an inexplicable persistence becomes legible as a cycle of irregular contact and response, one BB Easton can name even as she admits how difficult it has been to break.
