Can walking through a doorway make you forget? & Dr Karls Great Moments In Science (ABC Science) Dr Karl › Dr Karl's Great Moments In Science If you experience memory lapses when moving from one room to the next then you're not alone. Dr Karl wonders why we sometimes forget what we came for. By Karl S. Kruszelnicki Your memory is a funny thing. Or have you ever gone to the kitchen because you were thirsty and then forgotten why you were there? What's going on? Now for a bit of essential background. Also, the universe is a dangerous place. At least, that's the result of a psychology experiment by Dr Radvansky and colleagues from the University of Notre Dame in Indianapolis in the USA. He was exploring these memory lapses in terms of what psychologists call an event-horizon model. Secondly, if you're concentrating on something, it will take up most of your attention and everything else gets pushed into the background.
And finally, different parts of your memory system compete with each other to try and retrieve information. But what was the cause? ^ to top. IQ Drops When You're In a Group | Psych Central News - StumbleUpon. By Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on January 24, 2012 Provocative new research discovers small-group dynamics can lower the expression of IQ in some susceptible people. In the study, researchers determined IQ is significantly linked to social context. During the investigation, scientists from the Virginia Tech Carilion Research Institute found that settings such as jury deliberations, collective bargaining sessions, and cocktail parties may reduce cognitive ability.
“You may joke about how committee meetings make you feel brain dead, but our findings suggest that they may make you act brain dead as well,” said Read Montague, Ph.D., director of the Human Neuroimaging Laboratory and Computational Psychiatry Unit, who led the study. Researchers used functional magnetic resonance imaging (fMRI) to investigate how the brain processes information about social status in small groups and how perceptions of that status affect expressions of cognitive capacity.

Grooved fingers make us smart. ...as do grooved brains. When you are next in the shower, take a look at your wrinkled fingers. They aren't pretty to look at, but they help make you smart. Pruney fingers are not an accidental side effect of getting soaked as is typically believed, but are, instead, highly efficient rain treads that help us primates grip the world when it is wet ( something we've recently been studying in the lab ).
Without wrinkled fingers you would need to possess two categories of behavior, one for dry conditions, and one for wet. That would require more brain space than you can spare. Lucky for you, you can get by with just one set of behaviors ("all-weather-behaviors") because your fingertips and feet "know" when to change from race-tire-smooth to rain-tire-wrinkled. The strategy of "subcontracting" out brain responsibilities to low-brow reflex-like mechanisms is one of the oldest tricks in evolution's book. We humans are different. This is not to say we're not smart. Penn State Live - Psychologists chase down sleep demons.
UNIVERSITY PARK, Pa. -- What do Moby Dick, the Salem witch trials and alien abductions all have in common? They all circle back to sleep paralysis. Less than 8 percent of the general population experiences sleep paralysis, but it is more frequent in two groups -- students and psychiatric patients -- according to a new study by psychologists at Penn State and the University of Pennsylvania. Sleep paralysis is defined as "a discrete period of time during which voluntary muscle movement is inhibited, yet ocular and respiratory movements are intact," the researchers state in the current issue of Sleep Medicine Reviews.
Hallucinations may also be present in these transitions to or from sleep. Alien abductions and incubi and succubi, as well as other demons that attack while people are asleep, are implicated as different cultural interpretations of sleep paralysis. The Salem witch trials are now thought possibly to involve the townspeople experiencing sleep paralysis. Brian A. Welcome to Adobe GoLive 6. From Los Angeles Times: It's not all about you Chances are, others aren't judging you as harshly as you think, if at all. By Benedict Carey Times Staff Writer January 13, 2003 Oh, things sure took a bad turn. Take a deep breath. A growing body of research shows that far fewer people notice our gaffes than we believe as we pace the floor in private, going over and over the faux pas.
Learning to recognize this self-deception can soothe the anxiety that surrounds social interactions. The spotlight effect blinds us in several ways. A pioneer in this field, Tom Gilovich, a psychologist at Cornell, has demonstrated the same exaggerated misperceptions in several situations, such as group discussions about social issues. The findings apply to most of us, of course, but not to everybody -- some people really do live under a microscope, as a chosen way of life.
Most of the time a mistake is just a mistake, not a death sentence. Yet we don't expect that same empathy for ourselves. Seeing in the Dark & SEEDMAGAZINE.COM - StumbleUpon. Credit: cliff1066tm. Patient TN was, by his own account, completely blind. Two consecutive strokes had destroyed the visual cortex of his brain, and consequently, his ability to see. It is not uncommon for stroke patients to suffer brain damage, but the case of TN — referenced by his initials, the general practice in such studies — was peculiar. His first stroke had injured only one hemisphere of his visual cortex. About five weeks later, a second stroke damaged the other hemisphere. An assessment of his brain function revealed that after two strokes, TN, in his 50s, was clinically blind. Known as selective bilateral occipital damage, TN’s unusual injury made him the subject of much interest while recovering at a hospital in Geneva. To further test the extent of TN’s abilities, researchers from Tilburg University in the Netherlands devised a simple yet decisive experiment: an obstacle course.
TN’s rare condition is known as blindsight. 10 Psychological Experiments That Went Horribly Wrong. Psychology as we know it is a relatively young science, but since its inception it has helped us to gain a greater understanding of ourselves and our interactions with the world. Many psychological experiments have been valid and ethical, allowing researchers to make new treatments and therapies available, and giving other insights into our motivations and actions. Sadly, others have ended up backfiring horribly — ruining lives and shaming the profession.
Here are ten psychological experiments that spiraled out of control. 10. Stanford Prison Experiment Prisoners and guards In 1971, social psychologist Philip Zimbardo set out to interrogate the ways in which people conform to social roles, using a group of male college students to take part in a two-week-long experiment in which they would live as prisoners and guards in a mock prison. 9.
