Sudden Death Of Some Short-Term Memories

Thursday, April 30th, 2009

The human brain stores some kinds of memories for a lifetime. But when our eyes are open and looking at things, our gray matter also creates temporary memories that help us process complex tasks during the few seconds these visual memories exist. For decades, scientists have held that such short-term memories don’t suddenly disappear, but grow gradually more imprecise over the course of several seconds.

Now researchers at the University of California, Davis, have found just the opposite. Their subjects retained temporary memories of an object’s color or shape for at least four seconds. After that, the memories began to wink out like streetlights at daybreak, remaining quite accurate until they suddenly disappeared.

Study Suggests Buddhist Deity Meditation Temporarily Augments Visuospatial Abilities

Wednesday, April 29th, 2009

Meditation has been practiced for centuries, as a way to calm the soul and bring about inner peace. According to a new study in Psychological Science, a journal of the Association for Psychological Science, there is now evidence that a specific method of meditation may temporarily boost our visuospatial abilities (for example, the ability to retain an image in visual memory for a long time). That is, the meditation allows practitioners to access a heightened state of visual-spatial awareness that lasts for a limited period of time.

Normally when we see something, it is kept in our visual short-term memory for only a brief amount of time (images will begin to fade in a matter of seconds). However, there have been reports of Buddhist monks who have exceptional imagery skills and are able to maintain complex images in their visual short-term memory for minutes, and sometimes even hours. Led by psychologist Maria Kozhevnikov of George Mason University, a team of researchers investigated the effects of different styles of Buddhist meditation on visuospatial skills.

Brain Games: Do They Really Work?

Tuesday, April 28th, 2009

A recent multicenter clinical trial of a commercial brain fitness program makes a case for why we should take brain games more seriously.

Do you misplace your keys or regularly miss appointments? Do you often forget the names of people you know well? Do you feel like your memory is slowly getting worse? If so, then you may find yourself considering those brain games advertised everywhere. Sales pitches such as “where the sweat is figurative, but results are real” and “your brain will thank you” are amusingly alluring. But you may find yourself wondering whether they are really worth the time and expense. You shell out the money, play a few rounds and your brain will start spitting out names, dates and pin numbers like you’re 18 again—right?

Is there a seat of wisdom in the brain?

Monday, April 6th, 2009

Researchers at the University of California, San Diego School of Medicine have compiled the first-ever review of the neurobiology of wisdom – once the sole province of religion and philosophy. The study by Dilip V. Jeste, MD, and Thomas W. Meeks, MD, of UC San Diego’s Department of Psychiatry and the Stein Institute for Research on Aging, will be published in the Archives of General Psychiatry on April 6.

“Defining wisdom is rather subjective, though there are many similarities in definition across time and cultures,” said Jeste, who is the Estelle and Edgar Levi Chair in Aging, professor of psychiatry and neuroscience and chief of geriatric psychiatry at UC San Diego. “However, our research suggests that there may be a basis in neurobiology for wisdom’s most universal traits.”

Wisdom has been defined over centuries and civilizations to encompass numerous psychological traits. Components of wisdom are commonly agreed to include such attributes as empathy, compassion or altruism, emotional stability, self-understanding, and pro-social attitudes, including a tolerance for others’ values.
