Role of Inner Speech on Serial Recall in Children with ASD: A Pilot Study Using the Luria Hand Test

الملخص EN

This study was conducted to investigate the relation between the effect of articulatory suppression on the serial recall and severity of social impairments among children with autism spectrum disorders (ASD).

The Luria hand test (LHT) was administered to evaluate the capacity for serial recall in 13 children with ASD.

The LHT was administered under three conditions: control, under articulatory suppression, and under spatial suppression.

Performance on the LHT of children with ASD was significantly lower in terms of both articulatory suppression and the spatial suppression condition.

Moreover, the severity of social impairment in children with ASD was related to individual differences of effects of articulatory suppression on the LHT, but not with effects of spatial suppression.

These results support the notion that dialogic inner speech which mediates complex cognitive abilities has inherently social origins.
