Effects of context on judgements of odor intensities in humans 总被引:2,自引:2,他引:0
This study evaluated whether the intensity of previously smelled odors
could unintentionally influence the subsequent judgement of odor intensity.
The predicted context effect was based on the adaptation- level theory.
Before and 25 min after either WEAK or STRONG biasing odor concentrations,
51 subjects were required to rate the intensity of 10 different odor
concentrations of California Orange Oil. After the WEAK bias, subjects
judged the odor intensity as being stronger than they did after the STRONG
bias. Thus the intensity of odors smelled 25 min earlier can
unintentionally influence subsequent odor intensity judgement. The findings
are discussed in the light of two alternative explanations, namely, a
central implicit memory process and a stimulus- level-based change at the
peripheral level.
