Help solve riddle of chocolate's allure

IT HAS been the subject of movies, books and music and described as the ultimate sign of love. But why is chocolate so irresistible to certain people and not others?

Queensland University of Technology PhD researcher Stephanie Fay, from the Institute of Health and Biomedical Innovation, is looking for participants to help her solve this age-old question.

Ms Fay said her study would examine the way different people perceived the taste of sweet foods such as chocolate, using questionnaires and skin conductance tests.

"We will be asking the participants to watch short videos as well as completing small tasks and answering an electronic questionnaire," Ms Fay said.

"We will be looking in particular to see if different personality types perceive things such as taste differently."

Ms Fay said subtle changes in the body would also be monitored to see the effect the sweet treat had on different people.

"Psychological arousal can be spotted in things like slight perspiration of the palms and very slight changes in the skin's moisture," she said.

"Chocolate is obviously quite an emotive food and can have an effect on people that other foods don't.

"For some people, it's a first line of support when things go wrong."

Ms Fay said she hoped the study would eventually contribute to wider research about food preferences, eating behaviours and weight management.

"Aside from being tasty, chocolate is also very widely available," she said.

"It's often the first thing you see when you walk into some shops. We want to be able to understand why some people can walk straight past those displays and other people can't."
