The latest news about cognitive psychology, brain development and neuroscience research
People aren’t very accurate at predicting how good or bad they’ll feel after an event — such as watching their team lose the big game or getting a flat-screen TV. But afterwards, they “misremember” what they predicted, revising their prognostications after the fact to match how they actually feel, according to new research.
Although bilinguals tend to have smaller vocabularies in each language than do children who know one language, bilinguals may have an advantage when it comes to certain nonverbal cognitive tasks. Bilinguals tend to perform better than monolinguals on exercises that require blocking out distractions and switching between two or more different tasks.
By applying electrical current to the brain, researchers reporting online on November 4 in Current Biology, a Cell Press publication, have shown that they could enhance a person’s mathematical performance for up to 6 months without influencing their other cognitive functions. The findings may lead to treatments for the estimated 20 percent of the population with moderate to severe numerical disabilities (for example, dyscalculia) and for those who lose their skill with numbers as a result of stroke or degenerative disease, according to the researchers.
We all know how hard it is not to scratch when we have an itch. But how can an itch be alleviated? In a new study published today in the prestigious journal Neuron, researchers at Uppsala University present the surprising finding that the same nerve cells that are active when we experience heat pain are also associated with itching.
Most people are familiar with the concept that sentences have syntax. A verb, a subject, and an object come together in predictable patterns. But actions have syntax, too; when we watch someone else do something, we assemble their actions to mean something, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.
Anger is an interesting emotion for psychologists. On the one hand, it’s negative, but then it also has some of the features of positive emotions. For a new study published in Psychological Science, a journal of the Association for Psychological Science, researchers find that associating an object with anger actually makes people want the object—a kind of motivation that’s normally associated with positive emotions.
The language we speak may influence not only our thoughts, but our implicit preferences as well. That’s the finding of a study by psychologists at Harvard University, who found that bilingual individuals’ opinions of different ethnic groups were affected by the language in which they took a test examining their biases and predilections.
