What are Mass Trials in the context of behavioral instruction?

Mass trials refer to structured opportunities to practice skills in a concentrated manner. This approach involves repeating a specific task multiple times in a session, allowing the learner to gain proficiency and fluency with that skill. The structured nature of mass trials helps ensure that the learner is focused on mastering particular targets, which is particularly beneficial in behavior analysis.

In this context, mass trials can facilitate quick feedback, enabling the instructor to identify whether the learner is successfully acquiring the skill. It also aids in reinforcing learning by providing a clear, repetitive experience that can lead to greater retention of the skill being taught. The goal is to create a focused environment where the learner can practice intensely, leading to improved performance.

When considering the other options, the incorrect choices do not accurately capture the essence of what mass trials are. For instance, randomly repetitive tasks lack the structure necessary for effective skills acquisition; a one-on-one approach can be used in various formats beyond mass trials; and intermittent assessments focus on measuring progress rather than providing the focused practice that mass trials involve. Therefore, the understanding that mass trials are structured opportunities to practice skills is critical for effective behavioral instruction.
