Could it really take milliseconds for you to choose
between eating healthy foods or succumbing to your desire for tempting
desserts?
Researchers
at Caltech performed a study that tested this theory in order to see if it was
true. They asked the participants, after four hours of fasting, to choose
between one of two food items that would appear of the screen: healthy food
option or unhealthy food item. The participants would choose the one food item
that they would choose if it were in front of them at the moment. The results
showed that an average of 200 milliseconds was the time it took for a person to
choose how the food would “taste” rather than it being healthy or not. This
leads us to believe that when it comes to food and decision making an important
factor usually is between taste and health. However, could it lead us to regret
those food decisions later? What factors come into place when it comes to
decision making and regret?
Brian
Sweis a medical student discussed a few of these points during his lecture at
Loyola University Chicago. A big part of his lecture was discussing a study
that involved decision making in rats that gave insight on decision making and
regret. The article that correlated with this study was entitled, “Behavioral
and Neurophysiological correlates regret in rat decision making on a
neuroeconomic task.” In this study rats were given flavored pellet options to
choose from. Each pellet was given a time delay wherein the rat could choose to
stay and wait to receive the pellet, go for another, or miss the opportunity to
receive a pellet completely. However
there were instances where the rat would choose to leave one food option and
wait longer for the other. Within the experiment the rat would show a sense of
regret- looking back at their first option being more desirable. Because of
this, when another opportunity rose to receive the more desirable treat, the rats
were more likely to wait it out and hastily eat their reward. All of this
happens within a few seconds and each analyzes the cost to benefit within
milliseconds as well. This study gave insight on how these types of time
sensitive situations can be a factor in decision making.
Going
back to the recent study at Caltech, when it comes to time sensitive
situations, it becomes more of an instinctive response: what we want at the
moment, regardless of actually weighing the consequences that comes after the
decision. It was seen with the rats because after missed opportunities to
receive the desirable pellet, they opted to wait for the reward they considered
to be beneficial during latter experiments. However there are times where some
people do forego the risk and go straight for the reward and in this case it
was the cake. Maybe it is better for us to analyze the cost to benefit ratio
when it comes to choosing foods. It may reduce the amount of regret we have
later on.
