Abstract Repeated exposure can change the perceptual and hedonic features of flavor. Associative learning during which a flavor’s odor component is affected by co-exposure with taste thought to be central in this process. However, changes also arise due itself. The aim study was dissociate effects associative from without repeatedly presenting one together sucrose second alone. Sixty individual...

In this study, the role of sex and body weight in olfactory gustatory dimensions (pleasantness, intensity, familiarity) mullet cured roes, a marine rich-fat food with peculiar sensory attributes, was evaluated. One hundred seventy-seven participants were enrolled. Positive correlations observed between all taste odor dimensions. Women reported significantly higher intensity ratings than men. Mu...

BACKGROUND As evidenced in the DSM-V, autism spectrum disorders (ASD) are often characterized by atypical sensory behavior (hyper- or hypo-reactivity), but very few studies have evaluated olfactory abilities in individuals with ASD. METHODS Fifteen adults with ASD and 15 typically developing participants underwent olfactory tests focused on superficial (suprathreshold detection task), percept...

In Exp. 1, the "protheticity" of the pleasantness of a diverse set of relatively isointensive odorants was estimated using exponents from power functions fitted by an interative least squares procedure between scale values established by (a) magnitude estimation and (b) category rating and rank ordering. In Exp. 2, this procedure was applied to intensity data derived from quarter-log-step volum...

Preferences are traditionally assumed to be stable. However, empirical evidence such as preference modulation following choices calls this assumption into question. The evolution of such postchoice preference over long time spans, even when choices have been explicitly forgotten, has so far not been studied. In two experiments, we investigated this question by using a variant of the free choice...

AIMS Prior studies indicate that alcohol-dependent patients have impaired olfactory sensitivity, odor quality discrimination and identification ability. However, olfactory functioning with regard to the immediate, perception driven odor associations is unknown. Therefore, this study assessed olfactory judgements in nonamnesic and nondemented patients with alcohol dependence. METHODS Thirty al...
