Older adults have been shown to describe their happiness as lower in arousal when compared to younger adults. In addition, older adults prefer low arousal positive emotions over high arousal positive emotions in their daily lives. We experimentally investigated whether or not changing a few words in the description of happiness could influence a person's rating of their happiness. We randomly a...

the purpose of the present study was to determine the effect of increasing arousal and its effect on athletes' depth perception. participants of this study included the students of faculty of physical education and sport sciences. 58 students (23 female and 35 male, mean age: 23.3 and sd: 2.16) were selected randomly. participants performed the study tests under two motivational conditions...

Conflicting data exist regarding the sexual arousal patterns of post-operative male-to-female (MTF) women with Gender Identity Disorder. The purpose of this study was to examine objective and subjective aspects of the sexual arousal response using a vaginal photoplethysmograph. Fifteen MTF women viewed neutral and erotic audiovisual film segments while their blood flow patterns were monitored. ...

Previous research suggests that women's genital arousal is an automatic response to sexual stimuli, whereas men's genital arousal is dependent upon stimulus features specific to their sexual interests. In this study, we tested the hypothesis that a nonhuman sexual stimulus would elicit a genital response in women but not in men. Eighteen heterosexual women and 18 heterosexual men viewed seven s...

INTRODUCTION Female sexual arousal disorder (FSAD) is a complex diagnostic category whose definition continues to evolve. AIM The purpose of this study was to explore the physiological patterns of genital arousal in 31 women with and 30 women without sexual arousal difficulties using a vaginal photoplethysmograph. In addition, subtypes of FSAD, based on a recently proposed redefinition, were ...

We examined the convergent and discriminant validity of clitoral ultrasonography as a measure of female sexual arousal by assessing the following: (a) its ability to discriminate between sexual and other forms of arousal; and (b) its correlation with subjective ratings of arousal. Results from 63 healthy premenopausal women indicate that ultrasonography was not successful in differentiating sex...

State-dependent activity of locus ceruleus (LC) neurons has long suggested a role for noradrenergic modulation of arousal. However, in vivo insights into noradrenergic arousal circuitry have been constrained by the fundamental inaccessibility of the human brain for invasive studies. Functional magnetic resonance imaging (fMRI) studies performed during site-specific pharmacological manipulations...

The neural correlates of optimal states for signal detection task performance are largely unknown. One hypothesis holds that optimal states exhibit tonically depolarized cortical neurons with enhanced spiking activity, such as occur during movement. We recorded membrane potentials of auditory cortical neurons in mice trained on a challenging tone-in-noise detection task while assessing arousal ...

To investigate whether emotional arousal affects memorial feature binding, we had participants complete a short-term source-monitoring task-remembering the locations of four different pictures over a brief delay. On each trial, the four pictures were all either high arousal, medium arousal, or low arousal. Memory for picture-location conjunctions decreased as arousal increased. In addition, sou...
