Did you hear? Auditory prospective memory cues are more beneficial for autistic than for non-autistic children and adolescents
2021
Item does not contain fulltext Background: The transition from primary to secondary school is particularly difficult for autistic children, a transition underpinned by an increase in prospective memory (PM) demands. Aims: To better understand PM in autistic children of the relevant age range and its underlying processes, the current study investigated the impact of cue salience (distinctiveness) on PM in autistic and non-autistic children and adolescents. The study was unique in manipulating the visual and auditory salience of PM cues. Salient cues are assumed to put lower demands on executive control resources as compared to cues that blend in with the ongoing activity. Methods and procedu…
How Long Did You Look At Me? The Influence of Gaze Direction on Perceived Duration and Temporal Sensitivity.
2016
Faces that exhibit emotionally negative expressions in mutual gaze have been shown to induce a dilation of perceived duration. The influence of gaze by itself on duration judgments, however, has rarely been investigated. We argue for a social interaction hypothesis, according to which humans should be highly accurate and precise (sensitive) when processing the temporal dynamics of mutual gaze. In three experiments, we investigated whether the direction of observed gaze affects perceived duration and temporal sensitivity. In Experiment 1, subjects did indeed estimate the duration of direct gaze more accurately as compared to the duration of averted gaze. In Experiments 2 and 3, subjects had…
Sensory and affective components of symptom perception: A psychometric approach
2018
Psychological accounts of symptom perception put forward that symptom experiences consist of sensory-perceptual and affective-motivational components. This division is also suggested by psychometric studies investigating the latent structure of symptom reporting. To corroborate the view that the general and symptom-specific factors of a bifactor model represent affective and sensory components, respectively, we performed bifactor models applying confirmatory factor analytic approaches to the Patient Health Questionnaire-15 and the Checklist for Symptoms in Daily Life completed by 1053 undergraduate students. Additionally, we explored the association of latent factors with negative affectivi…
What represents a face? A computational approach for the integration of physiological and psychological data.
1997
Empirical studies of face recognition suggest that faces might be stored in memory by means of a few canonical representations. The nature of these canonical representations is, however, unclear. Although psychological data show a three-quarter-view advantage, physiological studies suggest profile and frontal views are stored in memory. A computational approach to reconcile these findings is proposed. The pattern of results obtained when different views, or combinations of views, are used as the internal representation of a two-stage identification network consisting of an autoassociative memory followed by a radial-basis-function network are compared. Results show that (i) a frontal and a…
Children's Learning of Unfamiliar Phonological Sequences
1971
4 groups of 15 4-, 6-, 8-, and 10-yr.-old children learned nonsense phonological sequences that varied in grammaticality by violating 0, 1, or 2 phonological rules of Ss' native language. The youngest age group made fewer errors in learning the most nongrammatical phonological sequences than in learning grammatical ones. With the 10- and 8-yr.-olds an opposite trend was found. The differences were not statistically significant. Implications for second language learning were discussed.
Odyssey Towards a Sirenic Thinking: An Attempt at a Self-Criticism of the Listening Paradigm Within Sound Studies
2021
Abstract This text departs from a contradictory claim in deaf studies and sound studies: both disciplines describe a hierarchical regime of the sensible – visuocentrism and audiocentrism – which they try to counter with conceptualisations as “acoustemology” or “deaf gain.” However, as we argue, they both thereby erect what they claim to overcome: a sensual regime that privileges one sense over another and a restricted conception of subjectivity deriving from it. First, we draw a philosophical line in the critique of sensual regimes. Then we propose a figure for the transcendence of the separation of the sensible: in re-reading of the myth of Odysseus and the sirens, we engage various exampl…
Statistical analysis of sensory profiling data. Graphs for presenting results (PCA and ANOVA)
2000
Abstract A principal component analysis is performed to analyse the matrix of median values, with 16 varieties in rows, and all descriptors in columns. Only texture descriptors contribute to the definition of the main axes. Six varieties are identified that score high on mealiness and low on moisture, the 10 other varieties are ordered according to a mashable axis which involves texture descriptors. Next we exclude texture descriptors since the main characteristics are already found, and mealy varieties since they are not suitable for steamed potatoes. A mixed linear model (ANOVA) with random subject effects is then used for each descriptor. Flavour and taste differences are found among the…
Application of replicated difference testing
2000
International audience; In a recent paper, Brockho and Schlich (1998, Handling replications in discrimination tests. Food Quality and Preference, 9(5), 303±312) proposed a statistically sound way of handling replications in dierence testing. In the present paper, this new test is applied to the data obtained in six experiments on non alcoholic beverages, where triangle tests were intensively replicated (between eight and 60 times) with groups of subjects composed of 12±61 students. The paper aims to estimate in these practical situations the extent to which a group of panelists is heterogeneous towards the ability of detecting a sensory dierence among two products. As the results indicat…
Taste perception and integration
2016
Revue; IntroductionThe sense of taste is essential for the evaluation of food quality. It allows, at the level of the oral cavity, to evaluate the caloric content of the consumed food, to detect the presence of salt, and protect us against the ingestion of toxic molecules. Our gustatory system allows the perception of different food constituents as alkali metallic salts (salty), acids (sour), sugars (sweet), and bitter compounds. Umami is a different taste, arising from the perception of amino acids, such as l-glutamate, and 5′-ribonucleotides. Other taste qualities are still a matter of debate, including fat taste, corresponding to the taste of fatty acids (Khan and Besnard, 2009), metalli…
Le goût : physiologie, rôles et dysfonctionnements
2013
Article de vulgarisation; National audience; The sense of taste involves multimodal sensory activation to detect and identify many flavors. Today, five primary tastes have been identified (sweet, salt, sour, bitter and umami). These are often combined to form complex tastes. The physiology of gustatory pathways is complex. The activation of gustatory receptors located in the mouth leads to an ascendant pathway through the neurons of the solitary nucleus in the brainstem and the neurons located in the thalamus. After the thalamus, the gustative signal modulates the ipsilateral primary taste cortex and then the secondary taste area. The secondary taste cortex, which combines representations o…
