What is a characteristic outcome of fixed-interval reinforcement?

The characteristic outcome of fixed-interval reinforcement is that it typically results in average and irregular performance. This form of reinforcement is based on providing rewards after a fixed amount of time has elapsed, such as giving a paycheck every two weeks. Because employees know when the reinforcement (e.g., paycheck) will occur, their performance may increase as the time for the reward approaches, but tends to fall off after the reward is received.

This cyclical pattern can lead to a variance in performance levels; thus, while it can motivate some employees as the time for reinforcement nears, it does not sustain consistently high levels of performance over time. The predictability of the reinforcement schedule may encourage some anticipation but does not necessarily lead to continuously elevated performance.

In contrast, other options do not align with the typical outcomes associated with fixed-interval reinforcement. For example, consistently high performance is more characteristic of reinforcement schedules that reward behaviors at varying intervals. Predictability in rewards does exist, but it does not inherently lead to higher overall performance on a continuous basis.
