Hunger can trigger cruel words from kind people.
A starved
dog lover might fantasize about punting the neighbor's Chihuahua that
just will not shut up. A puckish but otherwise nice person might snap at
a friend, "Bring me the freaking cheesesteak before I flip this TABLE!"
They
are, in a word, "hangry," or irrationally irritable, upset or angry
because of hunger. But how hunger turns into hangriness is a mystery,
says
Jennifer MacCormack, a
doctoral candidate at the University of North Carolina, Chapel Hill in
psychology and neuroscience, who wanted to understand the phenomenon.
"The mechanism isn't clear on how [hunger] affects your emotions or the
exact emotional processes," she says.
To find out, she designed some provocative experiments to rile up hungry people.
In
one of them, MacCormack had 118 undergraduates fast for five hours or
more and 118 others eat a meal before coming to her lab. "Psych 101
students, bless their heart," she says. "They didn't know this was a
study about feeling hangry." Unfortunately for them, MacCormack
concocted an experiment to annoy them and to see how they responded.
First, she had half the people in both groups write an
essay about emotions to direct their attention to how they were feeling.
The other half wrote an essay about a neutral, unemotional day. "We
wanted to see if [self-awareness] halts creating this hangry emotions
and behaviors," MacCormack says. Next, she had all of them go through a
long, arduous computer exercise. "I designed this fake task with colored
circles. The colors are really glaring and bright and hard to look at,
and it's a hard task with a hundred trials," she says.
Just as
the participant was about to finish the assignment, the program would
simulate a crash. "The blue screen of death would show up," MacCormack
says. The researcher would then go into the room and begin blaming the
person for the computer crash. "Oh, what buttons did you press? You must
have caused the crash," MacCormack says. "Then we let them stew for two
minutes. Nobody blew up at me, but some people looked nervous and
upset. A lot of eye rolls. People crossed their arms."
After a
couple of minutes, MacCormack would have the students fill out an
emotion questionnaire, designed to look like a research satisfaction
survey, and then let them go. All the students were made a little upset
by the experiment, but only the hungry students who hadn't written about
their emotions were especially angry.
"They thought the
experimenter was more judgmental," MacCormack says. "They said they felt
significantly more hate than other people."
In another
experiment, MacCormack had people look at positive, negative or neutral
pictures, such as a cute kitten, a snarling dog or a rock. When hungry
or sated people looked at positive or neutral pictures, they didn't feel
any strong emotional shift in any direction. But when hungry people
looked at negative images, they reacted much more strongly than those
who had eaten recently.
The
results were published in the journal
Emotion.
The findings suggest two things, says
Elizabeth Davis,
a psychologist at the University of California, Riverside, who didn't
work on the experiments. First, hunger alone isn't enough to make
someone hangry. "It's context," she says. Hungry people need to be in
some negative situation or subject to negative stimuli before they start
feeling hangry.
Second, it seems people are less likely to
become hangry if they are aware of their emotions. Hunger makes us
slightly unhappy to begin with, but we might not always realize that our
mood is shifting, Davis says. So, when we're beset by some woe – like a
mean graduate researcher – those negative feelings get directed toward
that trigger instead and result in an overreaction. Hunger "signals to
us that something is wrong — that it's time to eat," Davis says. But as
humans, we may misattribute that aversive feeling to something external
before we look into what our body is telling us."
But if you
are aware that you're feeling a little stressed because you're hungry,
it's easier to separate those feelings from how something else is making
you feel, MacCormack says. "It becomes more like, 'maybe that person
isn't a terrible person. Maybe I'm just hungry.' "
That insight
means there are ways for hangry people to cool themselves off a bit.
"Just being a bit more aware is helpful," MacCormack says. But the best
remedy is probably just to fix the source of the issue first. "If I do
notice I'm getting hangry, I just go and eat something. It has helped to
buffer some marital conflicts and stuff," she says.
The same
principle might apply to other physical states, too, Davis says. "One of
the neat things about this paper is this idea that [feelings regulating
the body like hunger] are physiology that may be more closely tied to
our emotional experiences than we thought," she says. So, any other
internal signals like feeling cold or hot or pain may have their own
versions of hangry.
