Final answer:
In a trial-based method of stimulus preference assessment, three ways to measure a learner's behavior are duration, frequency, and latency.
Step-by-step explanation:
In a trial-based method of stimulus preference assessment, three ways to measure a learner's behavior are:
- Duration: Observing how long the learner engages with a particular stimulus.
- Frequency: Counting the number of times the learner interacts with a stimulus.
- Latency: Measuring the time it takes for the learner to respond to a stimulus.
