Sort and beer: Everything you wanted to know about the sorting task but did not dare to ask
2011
author cannot archive publisher's version/PDF; International audience; In industries, the sensory characteristics of products are key points to control. The method commonly used to characterize and describe products is the conventional profile. This very efficient method requires a lot of time to train assessors and to teach them how to quantify the sensory characteristics of interest. Over the last few years, other faster and less restricting methods have been developed, such as free choice profile, flash profile, projective mapping or sorting tasks. Among these methods, the sorting task has recently become quite popular in sensory evaluation because of its simplicity: it only requires ass…
Salt and Aroma Compound Distributions Influence Flavour Release and Temporal Perception While Eating Hot-Served Flans.
2021
International audience; To counteract the negative effect of salt overconsumption on health, strategies have been developed to reduce the salt content in food products. Among them, two promising strategies based on odour-induced saltiness enhancement and the heterogeneous distribution of flavour compounds were combined and assessed in four-layer cream-based snacks. To investigate the relationship between saltiness enhancement, temporal release and perception of flavour compounds in hot snacks with heterogeneous distribution of salt and aroma compounds, complementary techniques were used: nose space PTR-Tof-MS (Proton Transfer Reaction-Time of Flight–Mass Spectrometry) to assess the release …
Le goût sucré, de l’enfance… à la dépendance ?
2013
Summary: Can one talk about addiction to sugar? Sugar is an important part of our diet, and an important source of pleasure, as of a young age. The definition of addiction involves that addictive substances act on the reward circuit, and lead to two symptoms, withdrawal and tolerance. Is it the case with sugar? According to the literature, brain activations in regions involved in the reward circuit are observed in response to “sugar”, and they differ according to the type of sugar (caloric carbohydrates, sweet or not; sweeteners). Besides, withdrawal and tolerance symptoms are not well characterized: food cravings often concern sweet foods, but there is a decrease with age of the preference…
Impact of Dietary Fiber Enrichment on the Sensory Characteristics and Acceptance of French Baguettes
2013
The purpose of this study was to evaluate the consequences of dietary fiber (DF) enrichment in standard or superior quality French baguettes. Sensory characteristics of five experimental breads and seven commercial breads were described by a trained panel using a conventional sensory profile. The same set of breads was also evaluated by a panel of consumers who had to rate their expected liking based on the external appearance of a whole bread and then their perceived liking based on the tasting of a sample of that bread. DF enrichment was responsible for deterioration in the expected and perceived liking of breads. However, this deterioration was less substantial when the DF enrichment was…
Perception of wine quality according to extrinsic cues: The case of Burgundy wine consumers
2013
International audience; The value consumers put on specific products depends on the information they can get from experience and from the commercial description of the products. For wine, this information derives mainly from tasting (intrinsic factors) and from the packaging of the bottles (extrinsic factors). The main purpose of this work is to compare different methodologies able to disclose the extrinsic factors playing an important role in wine quality perception of consumers. Twenty-four Chardonnay commercial wines were selected according to different criteria such as origin, denomination of origin and information provided in the label or back label. Forty-eight participants living in …
Special education without teaching assistants? : The development process for students with autism
2020
Many children may need the help of another person to attend school. It is common for children with disabilities to receive help from a teaching assistant at school. Assistants are provided in many countries as a legal right and are often publicly funded. It is also widely assumed that having teaching assistants in the class is an effective and cost-efficient way to support students with disabilities. In this study, the research task was to monitor and document the development process carried out by the teacher, with the aim of making visible the development of a more dynamic classroom interaction. The focus in this development process was the teacher’s idea of minimizing the conta…
Cognitive Biases in Pathological Health Anxiety
2016
Pathological health anxiety refers to the medically unfounded fear of suffering from a severe illness. Differences in cognitive processes related to attention, memory, and evaluation of health threat have been hypothesized to underlie pathological health anxiety. In no study, however, have researchers systematically and simultaneously assessed different cognitive biases. On the basis of the idea that multiple cognitive biases simultaneously contribute to psychopathology (the combined-cognitive-bias hypothesis), we compared 88 patients with pathological health anxiety, 52 patients with depressive disorder, and 52 healthy participants on their performance in several cognitive tasks involving…
Teaching hand-washing with pictorial cues
2016
<p><span style="font-family: Garamond; font-size: medium;">Applied behavior analysis has been shown to be an effective means to teach daily living skills to individuals with intellectual disability. In the present study pictorial cues based on task analysis, system of least prompts, and social reinforcement were used to teach a man with mild intellectual disability to wash his hands correctly. An ABAB reversal design was used with follow-up after two weeks. The results show a rapid increase in hand-washing skills.</span></p>
Examining the relationship between public speaking anxiety, distress tolerance and psychological flexibility
2020
Public speaking is an important skill for university students to learn and practice as they progress through education and into their careers. However, individuals often avoid facing public speaking, as they lack the skills to cope with the anxiety that arises when speaking in front of others. The current study aimed to investigate the relationship between public speaking anxiety, distress tolerance, and psychological flexibility. A sample of 95 college students completed psychological flexibility measures and self-ratings of public speaking anxiety before and after a public speaking challenge. A behavioral index of public speaking distress tolerance (i.e., speech duration) was also recorde…
The Causal Influence of Life Meaning on Weight and Shape Concerns in Women at Risk for Developing an Eating Disorder
2021
Background: Although previous studies have shown an inverse relation between life meaning and eating disorder symptoms, the correlational nature of this evidence precludes causal inferences. Therefore, this study used an experimental approach to test the causal impact of life meaning on individuals' weight and shape concerns.Methods: Female students at risk for developing an eating disorder (N = 128) were randomly assigned to the control or the meaning condition, which involved thinking about and committing to pursue intrinsically valued life goals. A color-naming interference task was used to assess the motivational salience of body-related stimuli, and self-report measures were used to as…
