Multisensory perception and attention in school-age children

Area of Science:

• Cognitive Psychology
• Developmental Neuroscience
• Auditory and Visual Perception

Background:

• Attention's role in modulating multisensory processes is established in adults and infants.
• This relationship remains under-explored in school-aged children.
• Understanding this interplay is crucial for cognitive development research.

Purpose of the Study:

• To investigate the relationship between specific attention abilities and multisensory processing in children aged 7-13 years.
• To examine how visuospatial, auditory sustained, and dual-task attention influence the McGurk and Stream-Bounce effects.
• To determine if age or intellectual abilities solely explain these attention-multisensory relationships.

Main Methods:

• Assessed attention using the Test of Everyday Attention for Children (TEA-Ch) subscales: Sky Search (visuospatial), Score (auditory sustained), and SSDT (audiovisual dual task).
• Measured multisensory processing via the McGurk effect and the Stream-Bounce effect.
• Analyzed correlations between attention scores and the magnitude of illusory percepts.

Main Results:

• Perception of both multisensory illusions generally increased with age.
• The McGurk effect was stronger in children with higher audiovisual dual-task attention (SSDT).
• The Stream-Bounce effect was more pronounced in children with higher auditory sustained attention (Score).

Conclusions:

• Specific attentional skills differentially modulate distinct multisensory illusions in school-aged children.
• The findings suggest that the integration of sensory information is influenced by the type of attention required.
• These relationships are not solely attributable to age or general intellectual capacity.
