Autism & Developmental

Autistic children's responses to separation and reunion with their mothers.

Dissanayake et al. (1997) · Journal of autism and developmental disorders 1997
★ The Verdict

Autistic preschoolers greet caregivers much like typical kids, but their reactions swing more from day to day.

✗ Skip if Clinicians focused only on vocal stereotypy or self-injury with no parent-child interaction goals.

01Research in Context

01

What this study did

The team watched preschoolers during a simple separation and reunion. Each child spent a short time away from mom, then came back together.

They compared three groups: kids with autism, kids with Down syndrome, and typically developing kids. All children were the same age range.

Observers coded how the children acted when mom left and when she returned. They looked for comfort seeking, crying, and greeting behaviors.

02

What they found

All three groups looked the same on average. Autistic kids showed the same spread of reunion behaviors as typical peers.

The only difference was consistency. Autistic and Down syndrome children changed their reactions more from one session to the next.

In short, the diagnosis did not predict attachment style, but day-to-day variability was higher in the two developmental disability groups.

03

How this fits with other research

Busch et al. (2010) extends these findings. They used the same three groups and also found no attachment split, but they added parent stress data. Mothers of autistic kids reported more strain even though reunion behaviors were normal.

Krupa et al. (2024) seems to disagree. They saw far less shared engagement in Tamil-speaking autistic preschoolers. The clash is only surface-deep: they measured joint play, not reunion comfort. Different context, different skill.

Martin et al. (1997), from the same lab and year, found autistic kids showed less positive affect during home play. Same sample, different setting. Together the papers show autistic children can greet caregivers warmly yet still show flatter emotion during free play.

Why it matters

You can reassure parents. A child who seems aloof during therapy may still greet them warmly after a separation. Use brief parent leave-and-return clips to show this strength.

Also, plan for variability. Because an autistic child’s reunion style may shift day to day, take two or three samples before you label the behavior as a treatment target.

03Original abstract

Observed 16 autistic, 16 normal, and 16 Down syndrome children (age 3-6 years during separation and reunion with their mother in a laboratory playroom over three sessions. Children's responses to separation and reunion were assigned to one of five behavioral patterns that were weighted for intensity or level of response. No differences were found between groups in their behavioral responses during separation or reunion. Moreover, children in each group altered their responses according to the environmental setting which was varied over the three sessions. However, the autistic and Down syndrome groups did differ from the normal group in their consistency of behavioral patterns over the three observation sessions; both the former groups showed more individual variation in their separation and reunion patterns indicating that the expression of these patterns may be influenced by their associated developmental delay.
