Social phobia has been associated with abnormal processing of angry faces, which directly signal disapproval--a situation that social phobics fear. This study investigated the electrophysiological correlates of emotional face processing in socially phobic and non-phobic individuals. Subjects identified either the gender (modified emotional Stroop task) or the expression of angry, happy, or neut...

BACKGROUND Recently, emotion recognition has become a hot topic in human-computer interaction. If computers could understand human emotions, they could interact better with their users. This paper proposes a novel method to recognize human emotions (neutral, happy, and angry) using a smart bracelet with built-in accelerometer. METHODS In this study, a total of 123 participants were instructed...

Although testosterone levels and muscle mass decline with age, many older men have serum testosterone level in the normal range, leading to speculation about whether older men are less sensitive to testosterone. We determined the responsiveness of androgen-dependent outcomes to graded testosterone doses in older men and compared it to that in young men. The participants in this randomized, doub...

Relationships among perceived stress, trait anger (general propensity to become angry), modes of anger expression, and health status were examined in a sample of 720 college students. Although stress was significantly correlated with trait anger and all four modes of anger expression, most correlations were of low magnitude. College men and women did not differ in trait anger, anger-in, or ange...

the study was carried out on 1300 in patients in isfahan medical school teaching hospitals during the last ten years. 1) 13.6% of patients complained pf pericardial pains but nothing wrong with their hearts. 2) more false pericardial pains were seen among young patients rather than c.h.d. in addition to these more false precardial pains among women with comparing to men. 3) the severity of c.h....

BACKGROUND Physiological responses to exercise of moderate intensity and duration among aged compared to young adults have yet to be clearly defined. Further, the effects of aging on the rate and effectiveness of postexercise recovery are unknown. METHODS Here, selected physiological responses during and following exercise of the same relative intensity were examined in untrained young and ag...

Participation in the “honor culture” of poor black inner cities puts young men on constant alert for challenges to their reputations. Hypothetically, this vigilance raises their testosterone (T), which in turn facilitates dominance contests that may end violently. One prior study reports the predicted hormonal pattern including higher T among young black men with low education, compared to youn...

According to the mitochondrial theory of aging, an age-related increase in oxidative stress is responsible for cellular damage and ultimately cell death. Despite compelling evidence that supports the mitochondrial theory of aging in some tissues, data regarding aging skeletal muscle are inconsistent. We collected resting muscle biopsies from the vastus lateralis, and 24 h urine samples from, yo...

A fundamental issue in human development concerns how the young infant's ability to recognize emotional signals is acquired through both biological programming and learning factors. This issue is extremely difficult to investigate because of the variety of sensory experiences to which humans are exposed immediately after birth. We examined the effects of emotional experience on emotion recognit...
