Ambient odors associated to failure influence cognitive performance in children

Area of Science:

• Psychology
• Neuroscience
• Behavioral Science

Background:

• Emotional experiences can create lasting associations.
• Sensory stimuli, like odors, are known to evoke memories and emotions.

Purpose of the Study:

• To investigate if odors can become conditioned to emotionally salient experiences.
• To determine if previously associated odors influence subsequent behavior.

Main Methods:

• Five-year-old children experienced failure/frustration on a cognitive maze in a scented room.
• Later, children completed a different cognitive task in rooms with the same, a different, or no odor.

Main Results:

• Children performed significantly worse when the test room had the same odor as the initial negative experience.
• Performance was equivalent in groups exposed to a different odor or no odor.
• Facial expressions and verbalizations during the initial task indicated negative affect.

Conclusions:

• Odors can be conditioned to specific experiential states.
• Re-exposure to conditioned odors can directionally influence behavior, particularly in negative contexts.
