Psychology is the study of human mental functions, behavior and processes.

Amphetamine use in adolescence can affect brain chemistry and behaviour

Amphetamine use in adolescence can cause neurobiological imbalances and increase risk-taking behaviour, and these effects can persist into adulthood, even when subjects are drug free. These are the conclusions of a new study using animal models conducted by McGill University Health Centre (MUHC) researcher Dr. Gabriella Gobbi and her colleagues.

Marital status, income level and age affect likelihood of depression in breast cancer survivors

This year, more than 230,000 women will be diagnosed with breast cancer and nearly 40,000 women will not survive their battle with cancer, according to the American Cancer Society. New research from the University of Missouri shows that certain factors, including marital status, having children in the home, income level and age, affect the likelihood of depression in breast cancer survivors.

Regular physical activity associated with lower risk of depression in old age

Regular physical activity is associated with a lower risk of suffering depression in old age. This is shown by one of the largest studies on elderly Europeans to have been carried out, by researchers at the University of Gothenburg, Sweden, among others. Research also shows that self-determined motivation and perceived competence are important factors in persuading elderly people to exercise more.

Birth control shot may impair a person's memory

The birth control shot Depo Provera offers a convenient alternative for women who don't want to remember to take a daily pill. Ironically, research from Arizona State University has shown the shot actually may impair a person's memory.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

Study: People with schizophrenia have weakened sense of body ownership

A study using a procedure called the rubber hand illusion has found striking new evidence that people experiencing schizophrenia have a weakened sense of body ownership and has produced the first case of a spontaneous, out-of-body experience in the laboratory.

Poor sleep quality in both early and late pregnancy has been linked to an increased risk of delivering preterm.

Loneliness breaks up a normal night's sleep

Loneliness is not only heartbreaking, it breaks up a normal night's sleep, a new study shows. Researchers say compromised sleep may be one pathway by which feelings of loneliness adversely affect our health.

Seven billion humans and counting

According to the United Nations Population Fund, the seven-billionth child is most likely to be a boy born in India or China, this week. However the trend of fertility or growth of population in the longer term is in a different direction toward slower population growth, says Dudley Poston, a professor of sociology and demographics at Texas A&M University.

Scientists pinpoint brain circuitry linked to decision-making

What drives addicts to repeatedly choose drugs, alcohol, cigarettes, overeating, gambling or kleptomania, despite the risks involved? Neuroscientists at the University of California, Berkeley, have pinpointed the exact locations in the brain where calculations are made that can result in addictive and compulsive behavior.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

UCLA's TIES for Families program receives $5,000 Disneyland grant

For the ninth year, the Disneyland Resort Cast Community Fund has awarded a $5,000 grant to UCLA's TIES (Training, Intervention, Education and Services) for Families program for its services and achievement. The UCLA-based program is dedicated to preparing and supporting adoptive families of children from foster care.

Microglia plays a key role in memory and learning

Immune system cells of the brain, which scavenge pathogens and damaged neurons, are also key players in memory and learning, according to new research by Duke neuroscientists.

Religion/spirituality may help buffer negative consequences of chronic health conditions

Individuals who practice religion and spirituality report better physical and mental health than those who do not. To better understand this relationship and how spirituality/religion can be used for coping with significant health issues, University of Missouri researchers are examining what aspects of religion are most beneficial and for what populations.

Writer's description of facial vividness linked to mirror neuron system

Celebrated writers such as Charles Dickens and George Eliot described characters' faces vividly without going into detail about their features, according to a research group led at the University of Strathclyde.

Energy Star- equivalent nutrition rating system for foods and beverages

Federal agencies should develop a new nutrition rating system with symbols to display on the front of food and beverage packaging that graphically convey calorie counts by serving size and a "point" value showing whether the saturated and trans fats, sodium, and added sugars in the products are below threshold levels.

Neuroscientists discover normal brain communication in people with AgCC

Like a bridge that spans a river to connect two major metropolises, the corpus callosum is the main conduit for information flowing between the left and right hemispheres of our brains. Now, neuroscientists at the California Institute of Technology have found that people who are born without that link-a condition called agenesis of the corpus callosum, or AgCC-still show remarkably normal communication across the gap between the two halves of their brains.

Future-Directed Therapy for patients with major depression

Patients with major depression do better by learning to create a more positive outlook about the future, rather than by focusing on negative thoughts about their past experiences, researchers at Cedars-Sinai say after developing a new treatment that helps patients do this.
