Their Messages Keep Changing. So Does Your Mood

Monday, they texted you three times before lunch. Warm. Funny. Full of plans. Tuesday, nothing. Wednesday, a single word. Thursday, a long message at midnight, full of feeling. Friday, nothing again. Logan follows mixed signals from intermittent reinforcement — unpredictable warmth is the most compelling schedule there is — through the contrast that makes warmth feel enormous after cold, the hope that ambiguity keeps alive, and the test that reads two weeks of contact as data, not feelings. Elena reads the messages. What was observed? Intermittent reinforcement produces the most persistent responding, and contrast changes judged intensity. How was it measured? Operant research on reinforcement schedules; contrast effects in judgment. Why is it important? The pattern decides whether you are responding to a person or to a schedule. What explanations are supported? Intermittent reinforcement plus contrast plus idealization under ambiguity. What remains unknown? How much of the attachment is schedule-driven versus person-driven in any given case. Sources: Skinner on variable and intermittent reinforcement; the contrast and idealization literature.
