Practitioner Development

A comparison of two approaches to training visual analysis of AB graphs.

Wolfe et al. (2015) · Journal of applied behavior analysis 2015
★ The Verdict

A 20-minute computer module or recorded lecture quickly makes adults better at reading AB graphs.

✓ Read this if BCBAs who train staff, supervise RBTs, or teach graph interpretation in any setting.
✗ Skip if Practitioners who already use long in-person graph workshops and see no need for a faster fix.

01Research in Context

01

What this study did

The team wanted to know if a short computer lesson could teach adults to read AB graphs.

They split adults into three groups. One group used a 20-minute computer module. One group watched a recorded lecture. The last group got no training.

Everyone then looked at graphs and judged slope and level changes.

02

What they found

Both trained groups scored much higher than the no-training group.

The computer module and the recorded lecture worked equally well.

A quick lesson, in either format, made people better at spotting trend and level shifts.

03

How this fits with other research

Bamise et al. (2026) took the same idea to Nigeria. They used a self-paced computer module to teach professionals to run pairwise functional analyses. Their results match Wolfe et al. (2015): short computer training can build real-world skills.

Doughty et al. (2010) reviewed BST studies for adults with intellectual disabilities. Their paper shows BST works for many adult skills, so the new graph-reading result is not a one-off.

Chase (1985) wrote the playbook. That old paper told designers to use behavioral prompts inside computer lessons. Wolfe et al. (2015) now give live data that the idea pays off.

Why it matters

You can stop hoping staff "just pick up" graph sense. Give them a 20-minute module or a lecture video before your next review meeting. Either one will raise the odds they spot true behavior change and avoid false alarms. Quick, cheap, and you can assign it tonight.

03Original abstract

Visual analysis is the primary method of evaluating data in single-subject research. Few studies have evaluated interventions to teach visual analys is skills. The purpose of this study was to evaluate systematic instruction, delivered using computer-based intervention or a recorded lecture, on identifying changes in slope and level in AB graphs. Results indicated that both approaches were significantly more effective than a no-treatment control condition but were not different from each other. We discuss the implications of these results for training and directions for future research.
