Does central coherence relate to the cognitive performance of children with autism in dynamic assessments?
Autistic children with weak central coherence and low nonverbal IQ show smaller gains on mediated dynamic tests, so interpret their scores carefully.
01Research in Context
What this study did
Mariam and colleagues gave a dynamic test to autistic children. A dynamic test gives short teaching bites and then retests to see how much the child gains from help.
They also measured two things: central coherence (how well the child sees the big picture) and nonverbal IQ. Then they asked, do these scores predict how much the child gains?
What they found
Every child improved after the mini-lessons. Yet kids with weak central coherence plus low nonverbal IQ improved less than their peers.
In plain words, the same help lifted some kids higher while others stayed closer to their first score.
How this fits with other research
Ohan et al. (2015) tracked toddlers with autism and found that many scored in the average range years later. Their message: early low scores can grow. Mariam’s team adds a warning: if both coherence and nonverbal IQ are low, growth during a brief test may still look small.
Courchesne et al. (2019) showed that strength-based tools reveal more ability in minimally verbal preschoolers. Together these papers tell us to pick tests that fit the child’s profile and to expect smaller gains when coherence and IQ are both weak.
Milgramm et al. (2021) found that teachers rate classroom competence by the same skills Mariam flagged: cognitive ability and social skills. The lab result and the classroom view line up—low NVIQ signals slower learning across settings.
Why it matters
When you give dynamic tests, check both central coherence and nonverbal IQ first. If both are weak, interpret small gains as a measurement issue, not a learning ceiling. Use this info to adjust teaching steps, not to lower goals.

03Original abstract
Central coherence refers to an in-built propensity to form meaningful links over a wide range of stimuli and to generalize over as wide a range of contexts as possible. In children with autism this ability is diminished, and the impact of central coherence deficits in children with autism have previously been observed using static measures of learning, such as reading comprehension test performance. In this study, the relationship between central coherence and more dynamic indicators of learning are investigated. The responses of 52 children with autism (mean age 9:10 years) on a test of central coherence and a dynamic assessment task were analysed. All the children showed significant improvements in dynamic assessment test scores after mediation; however, among those with below average nonverbal intelligence scores, weak central coherence was significantly associated with smaller gains in performance after teaching. Implications for the validity of dynamic assessments for children with autism are discussed.
