Why don't We Remember our Early Childhoods?

Setting in around age seven, childhood amnesia involves the sudden deletion of previous memories. The process underlying this phenomenon is also known as "pruning." While adult memory doesn't usually get lost during pruning processes, the lack of pruning tends to make the adult brain less flexible. A recent study, however, shows that there may be exceptions to this insight

What Is the Role of Consciousness?

Teens Texting for Free Help

A new service called Crisis Text Line allows teens to text a counselor from anywhere at anytime, all for free.

The Left-Hemisphere Hypothesis for Autism

About ten percent of autistic individuals have savant syndrome. This is difficult to explain on the fairly commonly accepted hypothesis that people with autism have less brain connectivity than normal folks. The left-hemisphere hypothesis explains the extraordinary skills in autism by pointing to data showing an asymmetry between their brain's right and left hemispheres.

The Immune Hypothesis for Synesthesia

A new hypothesis published in Frontiers in Neuroscience suggests that there might be a connection between atypical functioning of the immune system and synesthesia, a condition in which sensory or cognitive channels that normally are separate blend and lead to unusual, mixed sensory experiences or thoughts.

Hidden Talent Unleashed

Patrick Fagerberg had been working as a lawyer for 13 years when he was hit by a 30-foot steel camera boom. This incident would change his life forever. Though he had never had any interest in the arts, he developed a sudden talent for painting and recently signed a contract with a major gallery.

The Timing of Twinning

The current model of twinning suggests that twinning typically takes place two weeks after conception. This model has been used in defenses of the morality of contraception, stem cell research and IVF. Recent research suggests an alternative model, according to which twinning occurs around the time of conception. The new model, however, is not supported by the evidence.

Sloppy Psychology and Zero Tolerance Policies

Zero tolerance policies are purported to make our schools safer. But they simply aren't effective. Let's stop extorting innocent children in the name of deterrence.

Lightning results from a negative charge in the clouds that causes the ground to become positively charged, pulling the electrons toward it at a great force. When struck by lightning, people usually either die or suffer long-term negative consequences. However, in rare cases being struck by lightning can unlock the genius within.

"I Can Easily Beat BlackJack"

Do You Suffer From Emotional Pain or Anxiety? Pop a Tylenol

Emotional pain is often said to be very different from physical pain. Past studies have revealed that this is not quite right. The brain interprets physical and emotional pain in similar ways. A new study indicates that the brain also interprets anxiety as a kind of pain, and that these forms of psychological discomfort can be lessened by taking a Tylenol.

Micro-Inequities: 40 Years Later

In 1973 Mary Rowe of MIT coined the notion of micro-inequities: apparently small, hard-to-prove events that occur wherever people are perceived to be different. Rowe pointed out that micro-inequities, though they appear to be insignificant, can have seriously harmful effects when allowed to occur repeatedly. The problem of micro-inequities persists 40 years later.

Does Colorblindness Discriminate?

Some assume that colors appear the same to all of us. But research indicates that this isn't the case. It turns out that white male privilege exists even in objective theories of perceptual color experience.
