Hypothesis

Visual context, specifically the recognizability of visual information, influences flavor perception of odorized sweet beverages.

Conclusion

The degree of recognizability of visual information affects flavor perception differently, with figurative images enhancing sweetness ratings more than non-figurative images.

Supporting Evidence

  • Participants rated sweetness higher when exposed to figurative images compared to non-figurative images.
  • Sweetness ratings were significantly higher for strawberry-flavored stimuli compared to caramel-flavored stimuli.
  • Visual context priming was shown to have both sustained and transient effects on sweetness perception.

Takeaway

When you see pictures of sweet foods, it can make drinks taste sweeter, especially if the pictures look like the food.

Methodology

Participants rated the perceived sweetness of odorized sucrose solutions in the presence or absence of congruent or incongruent visual contexts.

Potential Biases

Participants may have experienced response biases due to the limited attributes available for rating sweetness.

Limitations

The study's findings may be influenced by the range of sweetness ratings participants were exposed to before the experimental trials.

Participant Demographics

Forty-eight healthy participants (mean age 23.4, SD 4.8, range 19–54 years, 20 male).
