E-Mail Which bananas end up in your shopping basket-- the uniformly yellow ones or those with brown spots? If you are like most people, you skip the spotted ones and select those that are perfectly yellow. This is because emotions play an an oversized role in our shopping decisions, according to a new study by Danish and Swedish researchers. "We choose food based upon an expectation of what it will taste like that is bound to our feelings. So, if we expect a brown banana to not match the taste of a yellow one, we opt for the latter," explains Karin Wendin, an associate professor at University of Copenhagen's Department of Food Science, and one of the researchers behind the study.
