  1. Patterns of Responding on Schedules of Reinforcement The Cumulative Record 70 60 50 40 30 20 10 0 Key measure of behavior: rate of responding Cumulative Responses This is the number of responses a subject makes in a period of time, like 1 minute. Time

  2. Patterns of Responding on Schedules of Reinforcement 70 60 50 40 30 20 10 0 A cumulative record shows total (cumulative) responses since the start of the session. Cumulative Responses By looking at the slope of the line on a cumulative record, you can instantly estimate the rate of responding. Time

  3. Patterns of Responding on Schedules of Reinforcement 70 60 50 40 30 20 10 0 The steeper the slope, the higher the rate of responding. Cumulative Responses A steep slope means the subject added a lot of responses to the total during that period of time: Time

  4. Patterns of Responding on Schedules of Reinforcement 70 60 50 40 30 20 10 0 A Increase Cumulative Responses B Line A adds more responses to the total than does Line B. Increase Time

  5. Patterns of Responding on Schedules of Reinforcement 70 60 50 40 30 20 10 0 A straight diagonal line means a constant rate of responding. Increase Cumulative Responses The number of responses added to the total is always the same from minute to minute. Increase Time

  6. Patterns of Responding on Schedules of Reinforcement 70 60 50 40 30 20 10 0 Negative Acceleration: Response Rate Decreases Over Time Cumulative Responses A curved line means that the rate of responding is changing. This is because the slopes are changing, and slope = response rate. Time

  7. Patterns of Responding on Schedules of Reinforcement 70 60 50 40 30 20 10 0 Positive Acceleration: Response Rate Increases Over Time Cumulative Responses Here, the slopes get steeper from minute to minute, so the response rate is increasing. Time
