All About Testosterone

Testosterone is far more than the stuff of the alpha male's swagger. It is present in both sexes and individual levels are correlated with language and cognitive abilities, not just with aggression and sex drive. Testosterone fluctuates according to age and life circumstance, often plummeting at the onset of parenthood, and spiking (for some) during moments of triumph.

Why Sex and Violence Go Together: Insights of Other Species

By Nigel Barber Ph.D. on July 24, 2015 in The Human Beast
In a recent post, I addressed links between violent crime and male sexual competition. Now, I want to ask whether animal analogies really illumine human aggression. If a young man kills an acquaintance in a Detroit bar, does this have anything to do with elephant seals battering each other to death in the breeding season?

Though there has been extensive research looking at the psychology of romantic love, is it possible to learn what can cause people to fall out of love with their significant other? For that matter, how is it possible to move on after a relationship comes to an end? A new article published in Review of General Psychology raises some intriguing questions about this.

Marketers' Shocking New Ability to Target Women

By Nigel Barber Ph.D. on March 03, 2015 in The Human Beast
During the fertile phase of their monthly cycle, women are prone to greater risk taking. For psychologists, this means that they are more likely to initiate sexual affairs. Marketers discovered that women are more likely to try new brands as well. Now they plan to use this fact in targeted marketing. Assuming that they get away with it, will the scheme work?

Attachment Styles Can't Change, Can They?

John Bowlby, the founding father of attachment theory, argued that the attachment style formed in early childhood often continues to shape a person’s behavior far into adulthood, permeating all future liasons. The attachment style of adults, however, need not completely reflect the child’s early interactions with a caregiver. Sometimes it undergoes a radical shift.

The Hipster, the Bearded Ape, and God

Most hipsters and other bearded types walk about sporting their facial coiffures unaware of their evolved purpose. But the allure of beards is rooted in the violent past of male mate competition.

Expanding on Penis Size

By Robert D. Martin Ph.D. on February 04, 2015 in How We Do It
Correlation between erect and flaccid penis lengths is a statistical artifact. On average, extension through erection is the same in all men. The “plunger hypothesis”, that human penis shape is adapted to remove semen from rival males, is shown to be far-fetched. But stretched length of the penis may have a connection with the size ratio between index and ring fingers.

The "Precarious Manhood" of the Santa Barbara Shooter

By Frank T McAndrew Ph.D. on February 02, 2015 in Out of the Ooze
Each new mass shooting prompts the same old explanations for the tragedy: the lack of attention paid to mental illness, the easy availability of guns, misogyny, and a socially-sanctioned sense of male entitlement. These explanations dance around the BIG question, which is why is it always a man who does this, and why is it almost always a young man?

Asexuality and the Health Professional

Asexual people are consistently told that their lack of sexual attraction is pathological. Worse yet, sometimes this message is reiterated by the medical and mental health professionals they trust. Those who hold the reins to define and improve health must become fully educated on asexuality, or their asexual clients may pay the price.
