To have understood which schedules of reinforcement produce a desired behavior, we examined whether a Fixed Ratio (FR) scale was more effective than a Fixed Interval (FI) scale. Subjects participated in an interview and were unaware that they were being reinforced on an FR, or FI schedule. Other studies have shown an FR scale to be more effective than an FI scale, so it was expected that FR schedules would produce more self-referenced statements (SRS) than FI in the last five minutes. The results didnt support this hypothesis since there was no effect of reinforcement on the number of SRS in the last five minutes (p>.05). Variability in the data could have influenced the results.
