Effects of pre-exposure concentration in neophobia and taste aversion learning
… to testing for conditioned taste aversion or neophobia. Pre-exposure to high saccharin concentration attenuated neophobia and taste aversion to high and low concentrations. Pre-exposure to the low concentration attenuated neophobia to both concentrations but attenuated taste aversion only to …

A critical evaluation of neophobia in corvids: causes, consequences and conservation implications
Neophobia, or the fear of novelty, is thought to restrict animals’ ecological niches and hinder their propensity for innovation; two processes that should limit behavioural adjustment to human-induced changes in the environment. However, birds within the corvid family ($\textit{Corvidae}$) defy …

Parental Perspective and Feeding Practices Effects on Food Neophobia in Elementary-Age School Children
<p>The Food neophobia (FN) behaviors in children are developed during childhood and can be influenced by parental FN and feeding behaviors. The objective of this study was to evaluate the relationship between FN and fruit and vegetable neophobia (FVN) among parents, the parents-reports on child's …

Effects of diversity training and a retention interval on neophobia and conditioned taste aversion
… followed one or 28-days later by testing for neophobia and training and testing for conditioned taste aversion to saline. At the one-day interval, preexposures to saline, hydrochloric, or multiple flavors attenuated neophobia to saline while only preexposures to saline attenuated the …

Phobic finches: Investigating neophobia reactions in a colour polymorphic specialist, the Gouldian finch, Erythrura gouldiae.
… on specialist species to adapt to these changes. Neophobia is an ecologically relevant and adaptive fear behaviour, functioning to allow animals to avoid danger. However, cognitive mechanisms such as neophobia are seldom investigated within conservation research. This thesis examines the neophobic …

Effects of novel ingesta from novel presenters on food acceptance in infants of different ages
… study investigated food acceptance/ingestional neophobia as a function of distal and proximal sources of stimulus novelty in human infants of two ages and evaluated the utility of the two-stage model of ingestion (e.g., Garcia, Hankins, & Rusiniak, 1974) in understanding the role of novel cues …

Effects of emotional state and food novelty on preschool children's acceptance of food
… familiar ones, a phenomenon termed ingestional neophobia. Young children display especially high levels of neophobia, spitting out new foods but accepting those same foods after familiarization. Rejection of novel foods presumably reflects the aversiveness of the food's novel sensory cues, which …

The Effects of Allopregnanolone on Feeding: A Behavioural Investigation
… when it was novel, indicating a reduction in neophobia (food related). In a lickometer/automated open field test, allopregnanolone significantly reduced thigmotaxis produced by exposure to a novel environment further indicating a reduction in neophobia (environment related). However, …

EARLY-LIFE DEVELOPMENT OF ANTIPREDATOR BEHAVIOUR OF JUVENILE NORTHERN CRAYFISH (FAXONIUS VIRILIS)
… including generalized responses to novelty (neophobia) and the ability to learn predator recognition through associative conditioning. However, the extent to which embryos can use risk-related information to shape future antipredator behaviour remains less understood, particularly in aquatic …

CANADIAN CONSUMER PERCEPTION OF GENOME-EDITED FOOD PRODUCTS
… food safety system, their food technology neophobia score, knowledge of genetics, and self-rated knowledge of genome editing. Food technology neophobia scores and knowledge both impact willingness to consume genome-edited and transgenics food products but not organic food products.

Variations in Consumer Rejection Thresholds of Water Samples Including Mixed-Berries Flavors
… and examine the effects of demographics, food neophobia status, and personality traits on the consumer rejection thresholds. The second part of this thesis aimed to distinguish and compare consumer rejection threshold methodologies with and without a control as well as determine the drivers of …

Investigation of ethnic food safety : microbiological and consumer behavioral approaches
… following variables: protection motivation, food neophobia, risk perception toward ethnic cuisines, food safety information, and consumer intention to visit ethnic cuisine restaurants. The results based on the structural educational modeling using AMOS 19 and ordinal logistic regression using IBM …

Evaluating the influence of individual traits, emotions and information on consumer acceptance of entomophagy : a choice modelling experiment
… studies have investigated the role of food neophobia and disgust sensitivity in modelling the acceptance of entomophagy, but the models lack explicit focus on individual traits and emotions in explaining variance in choice behaviour. Secondly, the experimental studies used to probe the role …

CONSUMMATORY RESPONSE STRENGTH IN THE ANALYSIS OF TASTE-AVERSION LEARNING
… findings on flavor salience, flavor preexposure, neophobia, enhanced neophobia, extinction, and deprivation effects. It is concluded that taste-aversion conditioning may be profitably studied within the context of a general process approach.</p>

Understanding the role of human microbiota on sensory perception
… correlate of sensory perception (food neophobia), olfaction (Chapter 2) and the oral microbiota (Chapter 3); and b) between distal gut (Chapter 4) or oral (Chapter 5) microbiota, taste functioning and dietary intakes are here presented. In Chapter 2 and 3, a healthy cohort of 83 …

The rejection of known and previously accepted foods in early childhood
… foods. It was further proposed that food neophobia would be the catalyst for these rejections. The data presented suggests that the rejection of previously accepted food is a common occurrence in pre-school children and provides some evidence that the categorisation of food and disgust may …

Brain and Cognitive Consequences of Early-Life Immune System Challenge in a Songbird
… song quality and learning, spatial learning, and neophobia. Immune challenge during this period of development did not produce long term impacts on learning or memory, nor did it lead to any changes in neophobic responses. However, birds that were hatched later in a clutch performed better on the …

The differential effects of stressors on aversive, novel and appetitive stimuli in rats
… CTA (aversive response) and saccharin neophobia (novelty) but not saccharin consumption in saline-injected rats (appetitive response). Runway studies showed that footshock enhanced the response to reward reduction (aversive response) but had not impact on runway responding when reward …

Sociality, social learning and individual differences in rooks, jackdaws and Eurasian jays

Mediating role of corticotropin-releasing hormone (CRH) in anxiety and ischemia: Behavioural and physiological correlates
… The first experiment standardized the use of a neophobia-based feeding model for use as a behavioural index of anxiety. Using this model, the second experiment demonstrated that while exposure to an unfamiliar environment activates stress-relevant neural circuitry, activation of CRH receptors is …
