distorted room our pulp talk secrets 1

be yarie khoda tu ruzhaye ayande in matlaba be ham vasl mishan
distorted rom

The distorted room removes some of these clues by forcing you took look at the room with one eye from a fixed point, and other clues it deliberately tricks (like the shape of tiles on the floor, which look the same from left to right, but actually get smaller, because the tiles on the right are closer).

houghts have a free-wheeling quality(discourse ) and concepts seem connected in unusual and playful ways. A study just published online in Psychiatry Research suggests that this effect may be due to the drug causing 'fast and loose' patterns of spreading activity in memory, something known as 'hyper-priming'.

Priming is a well studied effect in psychology where encountering one concept makes related concepts more easily accessible. For example, classic experiments show that if you see the word 'bird' you will react more quickly to words like 'wing' and 'fly' than words like 'apple' and 'can' because the former words are more closely related in meaning than the latter.

In fact, it has been shown that the more closely related the word, the quicker we react to it, demonstrating a kind of 'mental distance' between concepts. Think of it like dropping a stone into a pool of mental concepts. The ripples cause activity that reduces in strength as it moves away from the central idea.

'Hyper-priming' is an effect where priming happens for concepts at a much greater distance than normal. For example, the word 'bird' might speed up reaction times to the the word 'aeroplane'. To return to our analogy, the ripples are much stronger and spread further than normal.

(pulp?)

The experiment used a classic 'lexical decision task' where the volunteers are shown an initial word ('time') and then after a short gap are shown a nonsense word ('yipt') and a true word ('date') at the same time and have to indicate as quickly as possible which is the real world.

Killer whales, or orcas, have the second-biggest brains among all ocean mammals, weighing as much as 15 pounds. It's not clear whether they are as well-endowed with memory cells as humans, but scientists have found they are amazingly well-wired for sensing and analyzing their watery, three-dimensional environment

Scientists are trying to better understand how killer whales are able to teach one another specialized methods of hunting and pass on behaviors that can persist for generations — longer possibly than seen with any other species except humans.

"Culture is about learning from others," Whitehead said. "A cultural species starts behaving differently than a species where everything is determined genetically."

Equally remarkable to researchers is the orca's ability to communicate with whistles and pulsed calls, and to "see" by making a clicking sound that works like sonar.

"ma" alan jambandi knim

Many cetaceans — whales, dolphins and porpoises included — have these abilities to some degree. But orcas learn local and complex languages that are retained for many generations. And their bio-sonar, or echolocation, abilities also amaze researchers.

orca brain has a relatively smaller amount of cerebral cortex — the gray matter involved in memory, attention and thought — than the human brain does. But it has large-diameter myelinated axons, which carry nerve impulses.

"It's analogous to a computer that has maybe less memory but bigger wires," said Ridgway, who puts a high value on being able to work with orcas in captivity. "The bigger the axon, the faster the nerve impulses travel."ghabeliati ke gaho bigah mikhre be hashie pardazi

 It's a wild animal to begin with, and it has predatory behaviors that are well-known," Hof said. "It is pos

sible that, in a situation of stress or captivity or stress related to captivity,(bavaret mishe adama miga fek nemikardan to ashgh beshi

Like smoking in the 1970s, Dr. David Kessler says, there are no social boundaries when it comes to eating. It has become culturally acceptable to eat almost anywhere, and anytime — in a business meeting, in a lecture, in a classroom. "We have children who are eating almost constantly throughout the day."

What the food industry did was to take fat, sugar and salt, put in on every corner, make it available 24/7, make it socially acceptable to eat any time," Kessler says. "We've added the emotional gloss of advertisement, we've made the food into entertainment, and we're living the consequences.
The body doesn't recognize them well, and there's less compensation when people consume too much. Third is, they're so heavily promoted, it's ridiculous. And fourth, you've got this possibility of the sugar, especially coupled with caffeine, being addictive enough to be a problem."
Brownell and his colleagues published a study in December that showed such labels inspire people to eat 14 per cent fewer calories.

To tell somebody who has a weight problem to eat less and exercise more is not helpful."

Greene was an eater of fast food and pasta. Creamy, salty foods are what she loved, and the more the better. "It fed the emotional part of me that wasn't being filled with happiness." She hoarded food from an early age. "Food was my best friend, my comfort, the only constant in my life I could count on." Chips were her addiction. She would hide chocolate bars in her car, her bedroom, and snack on them when people weren't around

Being obese "was horrible, it was absolutely horrible. What was worse than the physical pain was the emotional pain."

ocial norms affect behaviour, Kessler says. We succeeded in changing how society views tobacco. "We used to see it as something glamorous and sexy and cool. Now we view it for what it is: a deadly, addictive product."
