The researchers tested how students reacted to critical supervision while lifting boxes, finding that stressed individuals used their muscles differently, leading to increased spinal forces.
A new study found that individuals with a sensation-seeking personality are more sensitive to nicotine's mood-altering effects, particularly at lower doses. This increased sensitivity may be a key factor in their risk of becoming smokers.
A study by University of Illinois researchers found that men tend to prefer economic-based goals, while women prioritize socially satisfying pursuits. The study used the Big Five personality taxonomy to analyze responses from college-aged students.

A new study by the American Psychological Association found that a firm handshake is associated with a favorable first impression for both males and females. The study suggests that consistent handshaking is related to personality traits such as extraversion and openness.
Research reveals a strong interaction between neuroticism and the serotonin transporter gene in influencing cigarette smoking behavior. Individuals with poorly expressed serotonin transporter genotypes and high levels of neuroticism face significant challenges in quitting smoking. This study suggests personalized approaches to smoking ...
Researchers found associations between certain personality traits and a polymorphic region in the human AP-2beta gene. These traits include muscular tension, guilt, somatic anxiety, psychasthenia, and indirect aggression. The study suggests a novel approach to understanding the genetic basis of psychiatric disorders and personality.
War has a devastating impact on children's mental health, leading to increased anxiety and depression. The study highlights the need for further research into the long-term effects of conflict on young minds.
Yale University has received a $3 million grant from the Personality Disorder Research Foundation to study borderline personality disorder. The three-year grant aims to better understand the disorder, its causes, and effective treatments for patients.
A study of 74 healthy African-American men found that hard-driving personalities can be beneficial when accompanied by job control and a fair amount of advancement opportunities. In contrast, those with little control over their workload and futures experienced increased cortisol levels, a stress hormone linked to health risks.
Research from the University of Birmingham found little evidence of exercise addiction among women, unless they have an eating disorder like bulimia or anorexia. The study showed no significant psychological problems among women who exercised excessively compared to non-exercisers.
Studies found that individuals with major depressive episodes and borderline personality disorder are at greater risk of suicide, while those with high serum cholesterol experience a doubled risk of violent suicide. Comprehensive mental health care is essential to address these co-existing illnesses.
A recent study suggests that environmental factors play a significant role in the development of psychiatric disorders, alongside genetic factors. Research findings indicate that adversity and social determinants can contribute to the onset of conditions like post-traumatic stress disorder, depression, and antisocial personality disorder.
Researchers found that men with Antisocial Personality Disorder have significant deficiencies in the prefrontal cortex, a brain region enabling moral sensibilities and self-restraint. The study bolsters the link between damage to this region and the acquisition of antisocial behavior.
Researchers have identified key factors contributing to the gender difference in depressive symptoms, including lower mastery over life areas and chronic strain. Women are more likely to get caught in a cycle of despair and passivity due to these interactions.
A new study published in Health Psychology contradicts long-held notions about the connection between breast cancer and psychological factors. The researchers found modest associations with certain psychosocial factors, but emphasized that biology remains the primary factor in breast cancer development.
Thomas Holme, a chemistry professor and TV personality, receives the Helen M. Free Award for Public Outreach from the American Chemical Society for his efforts to increase public awareness of chemistry through TV appearances and local activities. His segments air on WTMJ-TV, reaching an audience of over 200,000 viewers since 1995.
A new study found that anger expression fluctuates according to situational factors, rather than being a stable personality trait. State measures of anger expression were significantly associated with the person triggering anger, location, mood, and appraisal variables.
