"Histrionic Personality Disorder lies in the dramatic cluster of personality disorders. People with HPD have a high need for attention, make loud and inappropriate appearances, exaggerate their behaviors and emotions, and crave stimulation. They may exhibit sexually provocative behavior, express strong emotions with an impressionistic style, and can be easily influenced by others. Associated features include egocentrism, self-indulgence, continuous longing for appreciation, and persistent manipulative behavior to achieve their own needs." Here is the thing that is really interesting and will likely surprise most people. There is a statistical anomaly. It turns out that the ratio of male to female individuals afflicted with HPD is very imbalanced. The gender breakdown of these individuals is approximately 80% female and 20% male, a disproportionate percentage of those males being openly homosexual. Now let's take a look at a predominantly male psychological category known as Asperger's Syndrome. People with Asperger's Syndrome tend to exhibit little interest in emotionally interacting with others. They are very good at systematizing and developing conceptual models and prefer to retreat into a world of logical abstractions. They are often socially inept, are not known for being terribly dramatic and seem to actively retreat from social situations. They have above average IQs, are emotionally detached, and tend to obsessively work to solve and finish a problem. About 85% of people with Asperger's Syndrome are male. Now, here's the really interesting thing. Psychologists are actually beginning to form two somewhat related hypotheses. First they are hypothesizing that HPD and Asperger's are on opposite sides of a spectrum. Most importantly, they are beginning to hypothesize that females may be more typically inclined to be concerned with emotional interactions and males may be more typically inclined towards dispassionate logic and systematizing. This is obviously still a controversial theory at this point, except experimental data has so far been backing it up surprisingly well. Any thoughts?
