Trust Your Gut - If You're Aware of Your Heartbeat: "All the songs that tell people to listen to their hearts may be truer than crooners realize, a new study says.
Test subjects who were more conscious of their heart rates were more likely to 'trust their guts' when making decisions - and in some cases that intuition paid off.
University of Cambridge researcher Barnaby Dunn and colleagues had 28 subjects play a virtual card game in which they could win money by choosing cards from four supposedly random decks. The game involved guessing whether a chosen card would be the same color as an already upturned card.
In actuality the decks were stacked, and it was only possible to win big by choosing from two of the four decks.
No matter what the participants guessed, they would be correct 60 percent of the time if they chose from deck A or B. They'd be right only 40 percent of the time if they chose from deck C or D.
'In the card game, there were good choices to make and bad choices, and when they make bad choices, their body should give them an arousal signal,' such as an increased heart rate, Dunn said."
