Do peoples’ personalities change after 30? They can, according to researchers who examined 132,515 adults age 21-60 on the personality traits known as the “Big Five”: conscientiousness, agreeableness, neuroticism, openness and extraversion. These findings are reported in the May issue of the Journal of Personality and Social Psychology, published by the American Psychological Association (APA).
Songs with violent lyrics increase aggression related thoughts and emotions and this effect is directly related to the violence in the lyrics, according to a new study published by the American Psychological Association (APA). The findings, appearing in the May issue of the Journal of Personality and Social Psychology, contradicts popular notions of positive catharsis or venting effects of listening to angry, violent music on violent thoughts and feelings.
Contrary to what you might expect, people in therapy reported no difference in their stress levels once the war with Iraq started – but that may be only because war was seen as just one more stressor in chronically stressful times, according to a new survey of psychologists by the American Psychological Association Practice Directorate.
When adolescents perceive religion as important in their lives, it may lower rates of cigarette smoking, heavy drinking and marijuana use, according to a study that tracked urban adolescents from middle school through high school. The researchers from the Albert Einstein College of Medicine found that the perceived importance of religion was particularly important for teens who were facing a lot of life stressors. These findings are reported in the March issue of Psychology of Addictive Behaviors, published by the American Psychological Association (APA).
Two styles of leadership – rewarding performance and building identification for the mission – used in combination are good predictors of simulated Army platoon unit performances during times of high stress and uncertainty, according to a study on leadership styles and performance. Transactional contingent reward leadership uses recognition and rewards for goals as motivating forces for its members. Transformational leadership builds personal and social identification among its members with the mission and goals of the leader and organization.
Age-related changes in the brain — the appearance, starting around age 60, of “white-matter lesions” among the brain’s message-carrying axons — significantly affect cognitive function in old age. White-matter lesions are small bright patches that show up on magnetic resonance imaging (MRI) of the brain. What’s more, hypertension may account for some of this cognitive impact. A full report on these relationships appears in the March issue of Psychology and Aging, which is published by the American Psychological Association (APA).
In a large longitudinal study that sheds new light on the association between marital status and happiness, researchers have found that people get a boost in life satisfaction from marriage. But the increase in happiness is very small — approximately one tenth of one point on an 11-point scale — and is likely due to initial reactions to marriage and then a return to prior levels of happiness. Data from the 15-year study of over 24,000 individuals living in Germany also indicates that most people who get married and stayed married are more satisfied with their lives than their non-married peers long before the marriage occurred.
Children’s viewing of violent TV shows, their identification with aggressive same-sex TV characters, and their perceptions that TV violence is realistic are all linked to later aggression as young adults, for both males and females. That is the conclusion of a 15-year longitudinal study of 329 youth published in the March issue of Developmental Psychology, a journal of the American Psychological Association (APA). These findings hold true for any child from any family, regardless of the child’s initial aggression levels, their intellectual capabilities, their social status as measured by their parents’ education or occupation, their parents’ aggressiveness, or the mother’s and father’s parenting style.
College students frequently have more complex problems today than they did over a decade ago, including both the typical or expected college student problems — difficulties in relationships and developmental issues — as well as the more severe problems, such as depression, sexual assault and thoughts of suicide. That is the finding of a study involving 13,257 students seeking help at a large Midwestern university counseling center over a 13-year period. Some of these increases were dramatic. The number of students seen each year with depression doubled, while the number of suicidal students tripled and the number of students seen after a sexual assault quadrupled.
Birth is a time of peril for the human brain, especially in pre-term infants. For vulnerable “preemies,” biochemical signs of reduced blood oxygen levels (hypoxia) soon after birth are associated with lower IQs and language skills. In 2001, premature babies were 12 percent of U.S. births – the highest level in 20 years, due in part to more multiple pregnancies, induced labor, and older mothers. The January issue of Neuropsychology, published by the American Psychological Association (APA) reports on links among pre-term birth, risk for birth hypoxia and cognitive problems, and reveals how the risk threshold for brain damage in preterm babies could be lower than thought.
Both sides of the brain play a role in processing emotional communication, with the right side stepping in when we focus not on the “what” of an emotional message but rather on how it feels. By studying blood flow velocity to each side of the brain, Belgian psychologists have opened a window onto the richness and complexity of human emotional communication. Their research appears in the January 2003 issue of Neuropsychology, published by the American Psychological Association.
Although individuals vary widely, on average, pre-term infants are markedly slower at processing information — including understanding what they see — than full-term infants. New research shows this deficit in processing speed is already present in the first year of life and the gap in performance does not narrow with age. The research is published in the November issue of Developmental Psychology, a journal of the American Psychological Association (APA).
Most patients seeking radical gastric bypass surgery suffer from some form of mental health problem and should first be evaluated by a mental health worker, according to a study completed by psychologists and surgeons at the Center for Weight Reduction at Montefiore Medical Center. “There is a high degree of psychopathology in this population, which could influence their ability to make informed consent and/or their reaction to the surgery and subsequent weight loss,” said the authors in an article published in the professional journal Obesity Surgery. The psychological aspect of obesity surgery is a little talked about topic, but is of increasing relevance today as the number of radical surgeries for obesity increases.
I’m sorry, what were you saying? I got distracted by this story from the American Psychological Association that says researchers have successfully mapped different aspects of attention to parts of the brain’s frontal lobes. Turns out that the once-monolithic concept of “attention” has at least three distinct processes that look to be functionally and anatomically different.
