Psychological research has shown that it doesn’t take much to put you in a bad mood. In fact, just reading the morning news can do it.
Experts also say that being in a bad mood slows your reaction time, and affects your basic cognitive abilities like thinking, speech, writing and counting.
But new research from Tel Aviv University’s School of Psychological Sciences now reveals that repeated exposure to a negative event neutralizes its effect on your mood and your thinking.
The study, published in Attention, Perception, & Psychophysics, has broad implications for understanding our emotions.
“A bad mood is known to slow cognition,” said Moshe Shay Ben-Haim, Ph.D.
“We show that, counterintuitively, you can avoid getting into a bad mood in the first place by dwelling on a negative event.
“If you look at the newspaper before you go to work and see a headline about a bombing or tragedy of some kind, it’s better to read the article all the way through and repeatedly expose yourself to the negative information. You will be freer to go on with your day in a better mood and without any negative effects.”
In the new study, researchers evaluated the “emotional Stroop task,” a commonly-used psychological test in evaluating a person’s emotional state.
In the test, participants are shown a number of words and asked to name the colors in which they are printed.
In general, it takes people longer to identify the colors of negative words like “terrorism” than of neutral words like “table.” The trend is particularly pronounced in people with emotional disorders, like depression or anxiety.
There are two general explanations offered.
One is that negative words are more distracting, and the other is that they are more threatening. According to both theories, the result is that fewer mental resources are available to identify the ink colors.
Neither explanation appears to predict sustained effects.
After the initial distraction or threat, people should be expected to return to identifying the ink colors of neutral words without a delay.
Indeed, the few previous studies that have been done on the subject show that it does not matter whether people are shown negative or neutral words first.
In the new investigation, researchers performed a series of four experiments involving the emotional Stroop task. They discovered the prior studies were biased by the way the test is administered.
In most cases, people are shown four or five negative words, along with four or five neutral words, in the test 10 to 12 times.
The researchers found, after being shown the same negative word only twice, subjects were able to identify the ink color without a delay.
On the other hand, when people are shown the negative words just once, they subsequently name the ink colors of neutral words more slowly. The existing theories can’t account for these results.
The researchers suggest an alternative explanation based on previous research. The negative words shown to people in the emotional Stroop task put them in a bad mood, but through repetition, the words lose their affective power.
The researchers’ explanation was supported by a questionnaire administered to people after they completed the task.
Those who had seen each negative word only once were put in a bad mood and suffered from sustained effects, while those who had seen the negative words repeatedly did not suffer from the same after-effects.
The participants who were in a bad mood also took longer to complete the evaluating questionnaire.
The researchers’ work could have a major impact on our understanding of emotions, attention and how we process cues in the environment. It could also influence the diagnosis and treatment of many disorders.
