Evaluating the function of social interaction using time allocation as a dependent measure: A replication and extension

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

Watching where kids choose to stand for ten minutes tells you if social attention is candy or poison.

✓ Read this if BCBAs doing early intake assessments in clinic or home programs.
✗ Skip if Clinicians who already have long, stable FA data on every client.

01Research in Context

01

What this study did

Morris et al. (2020) watched how seven autistic children spent free time.

Kids could play alone or with an adult. The team tracked minutes in each zone.

They used this simple count to decide if social time felt good or bad to the child.

02

What they found

Every child showed a clear preference. Some stayed near the adult; others walked away.

The time-allocation score matched later test results for all seven kids.

03

How this fits with other research

Lancioni et al. (2008) ran long functional analyses and still missed social reinforcers for one child. Time allocation spotted the function in minutes, not hours.

Cullinan et al. (2001) used full analog conditions to find why kids hit. Morris gives a quicker ruler for the same question.

Coffey et al. (2021) moved from assessment to full treatment for autistic kids with anxiety. Morris offers the first, fast step in that pipeline.

04

Why it matters

You can start therapy sooner when you know in ten minutes if social attention helps or hurts. Run the mini-observation while the parent fills out paperwork. If the child avoids you, plan escape extinction. If the child hovers, use praise and paired reinforcement. Either way, you skip a long FA and get to teaching faster.

03Original abstract

Call et al. (2013) described a method of assessing the function of social interactions that used time allocation as a dependent measure. The current study replicated the method described by Call et al. and evaluated several extensions aimed at increasing the feasibility and efficiency of the assessment and the utility of its results. Seven children diagnosed with Autism Spectrum Disorder (ASD) participated. Social interactions were concluded to be reinforcing for 5 participants and aversive for 2 partcipants. Time allocation data for all participants are presented as well as additional analyses related to patterns of switching toward or away from social contact and session duration. Implications of this study and its methodology as well as future directions in this line of research are discussed.
