A demonstration of classical conditioning of the human eyeblink to an olfactory stimulus.
While acquisition of the eyeblink conditioned response to a variety of stimuli has been widely studied, it has yet to be established that humans will demonstrate a conditioned response to an olfactory stimulus. In this study we present data to show that humans will demonstrate a classically conditioned eyeblink response to an olfactory stimulus. Ten participants were tested in a delay conditioning procedure with an olfactory stimulus presented in a heated, humidified stream of air via an olfactometer, allowing the precise control over stimulus duration necessary for delay conditioning. Trials on which odor alone was presented were administered to four additional participants. Establishing that humans will demonstrate an eyeblink conditioned response to an olfactory stimulus will allow further exploration of the pathways involved in classical conditioning and associative learning, as well as an analysis of conditioning pathways across sensory modalities.
