Getting 'hangry' and operating on an empty stomach can lead to poor decision making, a study has discovered.
Researchers at the University of Dundee assessed how hunger alters people's decision-making and found it causes people to make significantly different choices.
People - Reward - Date
It causes people to become impatient and makes them more inclined to settle for a small reward instead of waiting for a guaranteed larger one at a later date.
It includes food options but also seeps into bigger decisions, such as financial options.
Dr - Benjamin - Vincent - Research - Participants
Dr Benjamin Vincent led the research and asked 50 participants various questions about food, money and other forms of reward.
They were quizzed twice, once while famished, and again when stuffed with food.
People - Meal - Sooner - Food - Rewards
It, unsurprisingly, found that people who skipped a meal accepted sooner and smaller food rewards but satiated people did not.
People were offered hypothetical rewards, they can have it now, or twice as much in the future.
Hunger - Pains - Days - Reward
When eating normally and not suffering hunger pains, they were normally willing to wait for 35 days to double the reward.
However, after a day of not eating, this plummeted to only 3 days.
Result - Researchers - Effect - Decisions - Questions
The most surprising result, according to the researchers, was that the effect of short-sighted decisions expands beyond food-related questions.
The researchers found that being hungry actually changes preferences for rewards entirely unrelated to food.
State - Hunger - Effect - Decisions - Food
'We wanted to know whether being in a state of hunger had a specific effect on how you make decisions only relating to food or if it had broader effects, and this research suggests decision-making gets more present-focused when people are hungry,' said Dr Vincent.
'You would predict that hunger would impact people's preferences relating to food, but it is...
