Explosive growth in access to the Internet has created an unprecedented opportunity for the general public to acquire explicit erotic texts, images, services, and merchandise, but psychological scientists have not conceptualized antecedents or consequences of contact with Internet sexuality or conducted a significant amount of empirical research on these issues. The current analysis uses Intern...

A patient in her 20s was referred to us for psychological assessment due to her depression and suicide attempts. She mentioned being anorgasmic except when diapered and emphasized her erotic preference for diapers. Her childhood included maternal deprivation in an impecunious family headed by an irritable physically disabled father on social assistance. Given the maternal deprivation in childho...

In the mid eighteenth century, Enlightenment debates about women's social role prompted a flurry of discussions about motherhood. Advice manuals, images of mothers, and women's personal writings highlighted breastfeeding as one of the most important maternal duties. This thesis argues that by the end of the eighteenth century advice manuals developed a new focus on the emotional and physical pl...

One fundamental question concerning brain reward mechanisms is to determine how reward-related activity is influenced by the nature of rewards. Here, we review the neuroimaging literature and explicitly assess to what extent the representations of primary and secondary rewards overlap in the human brain. To achieve this goal, we performed an activation likelihood estimation (ALE) meta-analysis ...

This investigation was designed to examine the effects of acute exercise on physiological and subjective sexual arousal in women. In Experiment 1, Ss participated in two experimental sessions in which they viewed a neutral film followed by an erotic film. In one of these sessions, Ss were exposed to 20 min of intense exercise prior to viewing the films. Subjective sexual arousal was measured wi...

The reinforcement sensitivity theory (RST) proposed the behavioral activation system (BAS) as a neurobehavioral system that is dependent on dopamine-irrigated structures and that mediates the individual differences in sensitivity and reactivity to appetitive stimuli associated with BAS-related personality traits. Theoretical developments propose that high BAS sensitivity is associated with both...

Ammonia fixation has been shown to proceed through at least three major pathways in ureotelic animals (1, 2). These are carbamyl phosphate synthetase, glutamic dehydrogenase, and glutamine synthetase. Perhaps the most significant means for removal of exogenous ammonia is by its conversion to urea (3). The initial step in this conversion is the production of carbamyl phosphate in the liver. Carb...

Studies of subjective and genital sexual arousal in monosexual (i.e. heterosexual and homosexual) men have repeatedly found that erotic stimuli depicting men's preferred sex produce strong responses, whereas erotic stimuli depicting the other sex produce much weaker responses. Inconsistent results have previously been obtained in bisexual men, who have sometimes demonstrated distinctly bisexual...

OBJECTIVE The objective of this study was to identify patterns of brain activation elicited by erotic visual stimuli in patients treated with either Selective Serotonin Reuptake Inhibitors (SSRIs) or mirtazipine. METHODS Nine middle-aged men with major depressive disorder treated with an SSRI and ten middle-aged men with major depressive disorder treated with mirtazapine completed the trial. ...
