Touching Emotions, Smelling Shapes: Exploring Tactile, Olfactory and Emotional Cross-sensory Correspondences in Preschool-aged Children
A strong CHI contribution because it does more than show that preschoolers have cross-sensory mappings: it shows which mappings already resemble adult patterns, which do not, and offers a practical story-based protocol for studying very young children without forcing adult-style experimental tasks.

Review Summary
This paper stands out because it addresses a real blind spot in cross-sensory and multisensory HCI research: preschool-aged children are often discussed as important users of sensory technologies, but the field has had little grounded evidence about how they actually connect smell, touch, and emotion. The contribution is therefore both empirical and methodological. Empirically, the paper shows that some correspondences already look stable by ages 2-4, especially tactile-linguistic, tactile-olfactory, and olfactory-emotion mappings. At the same time, it identifies an important developmental divergence: tactile-emotion associations do not simply mirror adult patterns, and may instead be shaped by social imagination, anthropomorphism, and narrative framing. That is the most interesting departure from an easy common-sense reading of child development. Methodologically, the work is valuable because it adapts the study of cross-sensory correspondences to preschoolers through structured, story-based conversations rather than importing adult ranking or rating tasks. The paper is careful enough to acknowledge that this method has limits: verbal explanation is hard for some children, non-verbal preschoolers were excluded, and the intentionally small stimulus set narrows what can be claimed. Those limitations matter, but they do not undermine the core contribution. Instead, they clarify the boundary conditions and make the paper more credible. Overall, this is a foundational CHI paper: it gives the field a better account of early cross-sensory cognition, a usable protocol for future studies, and concrete implications for designing sensory interfaces that align with how preschoolers actually reason rather than how adults assume they do.
What Changed
Canon before
Previous work on cross-sensory correspondences primarily studied adults and older children; sensory integration involving olfaction and touch in preschoolers was unexplored. Assumptions included that preschoolers' cross-sensory mappings align with adult patterns and that olfaction is underutilized in child-computer interaction.
Departure from common sense
Preschoolers show stable tactile-linguistic, olfactory-emotion, and tactile-olfactory correspondences similar to adults, but tactile-emotion associations differ, sometimes inverting adult patterns. The paper argues that some correspondences emerge early and remain stable, while tactile-emotion mappings are still developing and grounded in social imagination and narrative reasoning.
Actual novelty
The paper contributes empirical evidence of smell-touch-emotion correspondences in preschool-aged children, identifies developmental continuities and divergences relative to older groups, and presents a replicable story-based method plus design guidelines for sensory interfaces aligned with preschoolers’ sensory integration.
Evidence
Grounded evidence comes from the introduction, study description, discussion, limitations, and conclusion. The paper studies 26 children aged 2-4 using structured story-based conversations, reports significant tactile-linguistic, tactile-olfactory, and olfactory-emotion correspondences, highlights a developmental divergence in tactile-emotion mappings, and explicitly states limitations around verbal explanation demands and the intentionally limited stimulus set.
“ Building on this perspective, we contribute: (1) empirical evidence of smell–touch–emotion correspondences in preschool children, (2) methodological insights demonstrating the value of narrated, child-centered approaches for eliciting reasoning in this age group, and (3) design implications for cross-sensory technologies that support children’s communication and emotional expression by grounding interactions in cross-sensory correspondences”

Limits
Method limits
The method relies on structured story-based verbal responses, so some children struggled to explain their associations and non-verbal preschoolers were excluded. The intentionally limited stimulus set also constrained the range of correspondences that could be observed, and layered reasoning was simplified by the coding scheme.
Deployment limits
The findings are most applicable to preschoolers aged 2-4 in familiar, scaffolded settings with adult support and simplified tasks. The protocol may need adaptation for non-verbal children, broader sensory domains, and contexts without familiar staff or comparable story-based facilitation.
Boundary conditions
Results are bounded to 26 preschoolers aged 2-4, tactile, olfactory, and emotion correspondences, and a small set of stimuli and simplified response formats. The paper specifically studies tactile-linguistic, tactile-olfactory, olfactory-emotion, and tactile-emotion mappings under a narrated, developmentally tailored protocol.
Position in field
This paper fills a notable gap in multisensory HCI and child-computer interaction by extending cross-sensory correspondence research into preschool years and into smell-touch-emotion combinations. Its main value is not a new system artifact but a developmental empirical account and a practical method for studying very young children in a controlled yet child-appropriate way.
