TasteSensory Interaction
• Sensory interaction• Interaction of smell and taste
–McGurk Effect• Interaction of other senses
Olfaction• Sense of Smell• Chemical Sense• We can distinguish 10,000 scents• 40-50 molecules of a chemical allow us to recognize a smell• Particles are absorbed into mucus covering receptor cells
lining the nasal passages. This initiates smell• Each nostril has 30,000,000 olfactory receptor cells found
in the olfactory epithelium• No classification system has been agreed on• There is a strong connection between smell and memory
because they are processed in the same area of the brain.
Pheremones
• Powerful chemicals released by our bodies and detected by smell receptors
• Can act as a means of communication between animals
• Can influence physiological behavior• Debate over the extent to which humans use
them (animals rely on them heavily)
Other connections to smell:
• “branding” in stores• Aromatherapy• Air fresheners• Effect of smell on other senses
