How partners perceive each other’s emotion during a relationship fight

Some of the most intense emotions people feel occur during a conflict in a romantic relationship. Now, new research from Baylor University psychologists shows that how each person perceives the other partner’s emotion during a conflict greatly influences different types of thoughts, feelings and reactions in themselves.

Music releases neurotransmitter associated with drugs and sex

Scientists have found that the pleasurable experience of listening to music releases dopamine, a neurotransmitter in the brain important for more tangible pleasures associated with rewards such as food, drugs and sex. The new study from The Montreal Neurological Institute and Hospital – The Neuro at McGill University also reveals that even the anticipation of pleasurable music induces dopamine release, as is the case with food, drug, and sex cues.

Drugs for hair loss and BPH may result in loss of libido, ED in men

Researchers from Boston University School of Medicine (BUSM), in collaboration with colleagues at Lahey Clinic and from Denmark and Germany, have found that 5a-reductase inhibitors (5a-RIs), while improving urinary symptoms in patients with benign prostatic hyperplasia (BPH) and possible hair loss prevention, produces significant adverse effects in some individuals including loss of libido, erectile dysfunction (ED), ejaculatory dysfunction and potential depression.

People neglect who they really are when predicting their own future happiness

Humans are notoriously bad at predicting their future happiness. A new study published in Psychological Science, a journal of the Association for Psychological Science, suggests that part of the reason for these mispredictions lies in failing to recognize the key role played by one’s own personality when determining future emotional reactions.

Seeing foreigners as foreign encourages local coworkers to assist them

Whether it’s a company with local and ex-pat employees, countries in need of aid, or the elderly interacting with the young, a new research paper to be published in the journal Psychological Science says recognizing diversity can actually encourage people to help each other instead of sparking conflict.

Poker-faced professions take toll on employees

Employees who have to maintain a neutral disposition while they are on the clock tend to spend more energy to meet that requirement; therefore, they have less energy to devote to work tasks, according to new research from Rice University, the University of Toronto and Purdue University.

‘Timing is everything’ in ensuring healthy brain development

The Newcastle University researchers Dr Marcus Kaiser and Mrs Sreedevi Varier carried out a sophisticated computer analysis relating birth-time associated data to connectivity patterns of nerve cells in the roundworm, Caenorhabditis elegans. They demonstrated that when two nerve cells develop close together, they form a connection which then stretches out when the two nerve cells move apart as the organism grows. This creates a link across the brain known as a long-distance connection.

Study reveals impact of eating disorders on Native-Americans

Scientists in Connecticut have carried out one of the first psychological studies into eating disorders in Native American (NA) populations. The research, published in The International Journal of Eating Disorders, provides new insights into the extent to which Native American populations experience eating disorders, revealing that women are more likely to report behavioral symptoms then men, while challenging views that NA men and ethnically white men will experience different psychological symptoms.

‘Facebook neurons’ could provide insight into the neocortex

Carnegie Mellon University researchers have found that within the brain’s neocortex lies a subnetwork of highly active neurons that behave much like people in social networks. Like Facebook, these neuronal networks have a small population of highly active members who give and receive more information than the majority of other members, says Alison Barth, associate professor of biological sciences at Carnegie Mellon and a member of the Center for the Neural Basis of Cognition (CNBC).

College students lack scientific literacy

Most college students in the United States do not grasp the scientific basis of the carbon cycle – an essential skill in understanding the causes and consequences of climate change, according to research published in the January issue of BioScience.

Evidence lacking for widespread use of costly antipsychotic drugs

Many prescriptions for the top-selling class of drugs, known as atypical antipsychotic medications, lack strong evidence that the drugs will actually help, a study by researchers at the Stanford University School of Medicine and University of Chicago has found. Yet, drugs in this class may cause such serious effects as weight gain, diabetes and heart disease, and cost Americans billions of dollars.

Chemical signal in tears reduces sexual arousal in men

Emotional crying is a universal, uniquely human behavior. When we cry, we clearly send all sorts of emotional signals. In a paper published online today in Science Express, scientists at the Weizmann Institute have demonstrated that some of these signals are chemically encoded in the tears themselves. Specifically, they found that merely sniffing a woman’s tears – even when the crying woman is not present — reduces sexual arousal in men.
