The influence of instructive feedback presentation schedule: A replication with children with autism spectrum disorder

Nottingham et al. (2020) · Journal of Applied Behavior Analysis 2020
★ The Verdict

Skip every other instructive feedback trial to speed up learning without losing gains.

✓ Read this if BCBAs running discrete trial lessons with vocal children with autism.
✗ Skip if Clinicians working only with AAC users or adult populations.

01Research in Context

01

What this study did

The team compared three ways to give extra information during discrete trials. Kids with autism got the same primary task each time. The only change was how often the teacher added a bonus fact.

One schedule gave the extra fact every single trial. Another gave it every other trial. A third used a mixed pattern. Each child tried all three schedules in turn.

02

What they found

Every-other-trial worked best. Kids learned the bonus facts faster and kept them longer. Every-trial slowed things down. Mixed fell in the middle.

The same result showed up in every child. Less turned out to be more.

03

How this fits with other research

Yaw et al. (2014) also used instructive feedback with autistic kids. They saw gains even when the bonus words were shown every trial. The difference is they worked with children who used AAC devices. The current study used vocal learners. Same tool, different modality, same happy outcome.

Cubicciotti et al. (2019) tested trial order instead of feedback timing. They found the best order changes from child to child. Nottingham et al. found the best feedback schedule stayed the same across kids. Together the papers say: tweak the trial, not the kid.

Murphy et al. (2014) fixed stubborn errors by making consequences pop. Nottingham et al. fixed speed by spacing feedback. Both show small DTT changes can unlock learning.

Why it matters

You can cut your feedback in half and still get more learning. Try presenting the secondary target every other trial during familiar programs like sight words or labels. Track the data for a week. If the child keeps pace, you just saved time for extra trials or play. Less teacher talk, more kid progress.

03Original abstract

Instructive feedback (IF) is a modification to discrete trial instruction that may increase instructional efficiency for individuals with autism spectrum disorder. Several variations of IF have recently been evaluated in the literature; however, few studies have assessed the effectiveness and efficiency of presenting secondary targets on continuous versus intermittent presentation schedules. The current study evaluated the effectiveness and efficiency of various presentation schedules of secondary targets during discrete trial instruction. Specifically, we replicated and extended Griffen et al. (1998) by comparing a condition in which secondary targets were presented during each trial of a session, a condition in which secondary targets were presented every other trial, and a condition in which secondary targets were presented about every 4 trials. Within-subject replications were included for both participants. One of the intermittent presentation schedules was associated with the most optimal outcomes in all 4 comparisons.
