“…showed the higher level of food neophobia was associated with poorer chemosensory hedonic capacity. According to the studies by Raudenbush, Schroth, Reilley, and Frank (1998) and Raudenbush and Frank (1999), neophobic individuals rated unfamiliar foods more negatively in terms of hedonic rating than neophilics, which has also been reported in children with ASD (Luisier et al, 2015(Luisier et al, , 2019Qiu et al, 2022). Our results similarly suggested that neophobic individuals experience less pleasure from olfactory and gustatory stimuli.…”

Food neophobia, the reluctance to try novel food, is associated with numerous personality traits. Schizotypy, a subclinical phenotype of schizophrenia, consists of reduced severity of symptoms or traits of schizophrenia, which have been shown to consume a poor diet. However, there is no study directly examining the relationship between food neophobia and schizotypal traits. In addition, chemosensory hedonic capacity, the ability to experience pleasure simulated by smell or taste, is considered to be related to both schizotypal traits and food neophobia. Nevertheless, little is known about the role of chemosensory hedonic capacity on the relationship between schizotypal traits and food neophobia. In the present study, 2,581 college students completed the Food Neophobia Scale, Schizotypal Personality Questionnaire, and Chemosensory Pleasure Scale to examine food neophobia traits, schizotypal traits, and chemosensory hedonic capacity, respectively. Correlation analysis revealed that schizotypal traits were significantly positively correlated with food neophobia. Mediation analysis revealed that chemosensory hedonic capacity partially mediated the relationship between schizotypal traits, especially negative schizotypal traits and food neophobia. In conclusion, schizotypal traits were associated with food neophobia, and the relationship between schizotypal traits and food neophobia was mediated by chemosensory hedonic capacity. Practical Applications The present study is among the first to reveal that food neophobia was associated with schizotypal traits, which was mediated by chemosensory hedonic capacity. Therefore, our results might provide a new perspective of alleviating food neophobia by improving chemosensory hedonic capacity such as olfactory and gustatory training in the schizophrenia spectrum disorder.

“…Some studies have found that children with clinical and subclinical autistic traits as well as poor olfactory function showed more food neophobia behaviors (Luisier et al, 2015; Luisier, Petitpierre, Clerc Berod, Garcia‐Burgos, & Bensafi, 2019; Stafford et al, 2017; Wallace, Llewellyn, Fildes, & Ronald, 2018), which reduced the quality of life. Moreover, Qiu et al (2022) also found children with high autistic traits showed poor olfactory trait hedonic capacity, which may reduce the enjoyment of food and higher levels of food fussiness. It suggested that olfactory training (Mahmut et al, 2021), combined with sensory education, may improve the ASD children's olfactory ability, which may further help improve their eating behaviors.…”

Atypical olfactory function in autism spectrum disorder has been documented in numerous studies, but little is known about its occurrence in individuals with autistic traits. The aim of the current study was to investigate odor identification ability and olfactory hedonic capacity in children with autistic traits. We recruited 415 children and measured their autistic traits by the Short Autism Spectrum Quotient. The Universal Sniff (U‐Sniff) test was used to measure odor identification ability and olfactory hedonic capacity. Olfactory hedonic capacity was also measured using the children's version of the Chemosensory Pleasure Scale (CPS‐C). Odor identification and olfactory hedonic capacity measured by CPS‐C were negatively correlated with autistic traits. Children with higher autistic traits exhibited poorer odor identification ability and olfactory trait hedonic capacity measured by CPS‐C but intact olfactory state hedonic capacity measured by odor pleasantness. These results pertaining to odor identification and olfactory hedonic capacity may be the endophenotypic markers for autism spectrum disorder. Practical Applications Our study extends the knowledge on children with high autistic traits and provides a new perspective on olfactory identification ability and olfactory hedonic capacity in children with high autistic traits. In addition, our findings suggest olfactory testing may provide a new approach for detecting and understanding autism.
