Impact of processing load on analogical mapping with visual sequences in children with developmental language disorders (DLD)

Abstract

Background Analogical mapping is a domain-general cognitive process used notably in language development, and particularly in the abstraction of construction schemas. Children with developmental language disorders (DLD) display an impairment in linguistic productivity and creativity, which can be linked to a lack of generalization of construction schemas. Aims To investigate analogical mapping in children with DLD, and especially the influence of processing load, as it could explain the lack of creativity observed in children with DLD. It was hypothesized that analogical mapping is altered in children with DLD and that greater cognitive load (sequential presentation and no perceptual support) would be linked to poorer performance in these children. Methods & Procedures Fifteen children with DLD and their age-matched peers were administrated a visual analogical reasoning task where they had to complete a sequence sharing the same relational structure as previously presented sequences. Two factors influencing processing load were studied: the modality of presentation (sequential versus simultaneous) and the perceptual support (with versus without). Outcomes & Results Results showed an expected group effect with poorer performance in children with DLD compared with children with typical language development (TLD). Results corroborated hypotheses according to which children with DLD have difficulties with analogical mapping, which could hinder their abstraction of construction schemas. Results about the influence of processing load were mixed. While the difference between the two groups was more marked for the items without perceptual support than for those with perceptual support, children with DLD were not more affected by the sequential presentation than children with TLD. Conclusions & Implications Children with DLD have impaired analogical mapping competences, especially when the relational similarities are not supported by perceptual cues. This impairment may be the cause of their difficulties in abstracting construction schemas, thus provoking their poor linguistic productivity and creativity. However, more studies are needed to confirm this hypothesis, as the influence of analogical reasoning on language development could also be reversed or could be linked to another external factor.
