Which example illustrates variable practice?

• A. Practicing 'pat' across isolation, short phrases, and sentences with different rates and loudness
• B. Repeating 'pat' 30 times in the same rate
• C. Producing 'pat' in isolation first
• D. Repeating 'pat' with cues until 90% accuracy

Answer: (A)

Variable practice involves practicing a task under different conditions to build flexible control and better transfer to new situations. In this example, the sound "pat" is practiced across isolation, short phrases, and sentences, with varying rates and loudness. This variety forces the learner to adapt the motor pattern to different demands, strengthening generalized performance.

Repeating the same item at the same rate doesn’t change conditions, which is constant practice. Producing "pat" in isolation first describes a simple-to-complex progression rather than varying contexts. Repeating with cues until a target accuracy emphasizes feedback and accuracy criteria rather than practicing under different conditions.
