Smell and taste on a high: symposium on chemical senses: from genes to perception.

The 15th International Symposium on Olfaction and Taste.

Chemosensory cross-modal stroop effects: congruent odors facilitate taste identification.

In order to explore the cross-modal cognitive associations between smell and taste, a chemosensory analogue of the Stroop task (Stroop 1935) was developed. Fourteen participants were presented with an odorant and a tastant and asked to identify the tastant as "sweet" or "sour" by pressing 1 of 2 buttons as quickly as possible. Participants were faster to name the taste when it was presented wit...

Aging and the Chemical Senses

Everyone is aware that the visual and auditory senses dim with age, and expects the elderly to need reading glasses and hearing aids. What about the chemical senses of smell and taste? In what ways do our perceptions of the volatile and water-soluble molecules we smell and taste change? How pronounced is that change? And how early in life does it begin? Before addressing these questions, it is ...

A longitudinal descriptive study of self-reported abnormal smell and taste perception in pregnant women.

Self-reported abnormal sensitivity, qualitative distortions and phantom sensations with respect to smell and taste was assessed with a longitudinal design, based on questions referring to gestational weeks 13-16 and 31-34 of pregnancy in comparison with 9-12 weeks post partum and with non-pregnant women with corresponding time durations and intervals. The results show that abnormal smell and/or...

The Chemical Senses in Birds

The chemical senses generally fall into three categories: chemesthesis (irritation and pain), olfaction (smell), and gustation (taste). Traditionally, the emphasis in describing responsiveness to chemical stimuli has been placed on taste and smell. The reality is more complex. For example, the sensory afferents for chemesthetic perception are in close proximity with olfactory receptors in the n...
