We assessed young children's ability to discriminate visually between food and nonfood items, and the possible relationship between this ability and their level of food neophobia. A sample of 42 children, aged 36-53. months, performed a rapid categorization task in which they were shown a series of color photographs of food and nonfood items, each displayed for 80. ms. Their task was to say as quickly as possible whether or not each item was edible. We measured both accuracy (hits, false alarms, discriminability) and response times. The children's food neophobia score was assessed on a standardized scale. Results indicated that children had a high rate of hits (81%), but also a high rate of false alarms (50%). Discriminability and neophobia both increased with chronological age, and response times decreased. There were no significant correlations between categorization performances and food neophobia scores after controlling for age effects. We conclude that children aged 3-4. years have a liberal food categorization system, accepting large numbers of nonfood items as edible. © 2015 Elsevier Ltd. Source

Food neophobia and picky/fussy eating behavior are presented as the two main forms of children's food rejections which are responsible for a reduction of their dietary repertoire. We review the key factors, presented in the literature, that are involved in food rejections during childhood. We first consider a range of "cognitive factors", such as food perception, mental representations, categorization of food items, and emotions and feelings toward food. Next we focus on "social and environmental factors", as these might also significantly influence and modulate children's food rejections. We then summarize the findings to provide a comprehensive view of the factors involved in children's food rejections. Finally, we discuss the need for future studies on food rejections, regarding (i) the distinction between food neophobia and picky/fussy eating, and (ii) the potential link between food categorization abilities and children's food neophobia and pickiness. © 2015 Elsevier Ltd.
