“…We examined the different classification strategies used at different development stages from 6 years to adulthood to infer the development of the cognitive organization of everyday sounds. In light of the observation of a progressive acquisition of categorization skills in the visual and olfactory domains [ 16 , 17 ], we hypothesize that a similar developmental progression can be observed in the auditory modality. Further, since auditory perception improves during childhood, we hypothesize that the comprehension of complex sounds, as observed by a FST, will also change during development.…”

“…The most frequent is taxonomic categorization [ 16 ], which is a type of grouping based on a shared knowledge of the same common semantic properties, such as the furniture, the animals, the vegetables, etc. In addition to vision, recent studies have been able to show age-dependent taxonomic categorization for olfactory stimuli [ 17 ].…”

Perception of Everyday Sounds: A Developmental Study of a Free Sorting Task

ObjectivesThe analysis of categorization of everyday sounds is a crucial aspect of the perception of our surrounding world. However, it constitutes a poorly explored domain in developmental studies. The aim of our study was to understand the nature and the logic of the construction of auditory cognitive categories for natural sounds during development. We have developed an original approach based on a free sorting task (FST). Indeed, categorization is fundamental for structuring the world and cognitive skills related to, without having any need of the use of language. Our project explored the ability of children to structure their acoustic world, and to investigate how such structuration matures during normal development. We hypothesized that age affects the listening strategy and the category decision, as well as the number and the content of individual categories.DesignEighty-two French children (6–9 years), 20 teenagers (12–13 years), and 24 young adults participated in the study. Perception and categorization of everyday sounds was assessed based on a FST composed of 18 different sounds belonging to three a priori categories: non-linguistic human vocalizations, environmental sounds, and musical instruments.ResultsChildren listened to the sounds more times than older participants, built significantly more classes than adults, and used a different strategy of classification. We can thus conclude that there is an age effect on how the participants accomplished the task. Analysis of the auditory categorization performed by 6-year-old children showed that this age constitutes a pivotal stage, in agreement with the progressive change from a non-logical reasoning based mainly on perceptive representations to the logical reasoning used by older children. In conclusion, our results suggest that the processing of auditory object categorization develops through different stages, while the intrinsic basis of the classification of sounds is already present in childhood.

“…By this model, odor perception is not the basis of spatial organization, but, on the contrary, would be expected to emerge based on natural stimulus statistics. Experiments with children of different ages suggest that category formation is influenced increasingly with age by cognitive factors (Valentin and Chanquoy, 2012).…”

This is especially problematic at higher levels of processing, where complex cues elicit highly specific responses. In olfaction, this relationship is particularly obfuscated by the difficulty of characterizing stimulus statistics and perception. The core questions in olfaction are hence the so-called stimulus problem, which refers to the understanding of the stimulus, and the structure-activity and structure-odor relationships, which refer to the molecular basis of smell. It is widely accepted that the recognition of odorants by receptors is governed by the detection of physico-chemical properties and that the physical space is highly complex. Not surprisingly, ideas differ about how odor stimuli should be classified and about the very nature of information that the brain extracts from odors. Even though there are many measures for smell, there is none that accurately describes all aspects of it. Here, we summarize recent developments in the understanding of olfaction. We argue that an approach to olfactory function where information processing is emphasized could contribute to a high degree to our understanding of smell as a perceptual phenomenon emerging from neural computations. Further, we argue that combined analysis of the stimulus, biology, physiology, and behavior and perception can provide new insights into olfactory function. We hope that the reader can use this review as a competent guide and overview of research activities in olfactory physiology, psychophysics, computation, and psychology. We propose avenues for research, particularly in the systematic characteriza...
