Without knowing your body's position and movement, you couldn't put food in your mouth, stand up, or touch someone.
You couldn't do the simple act of taking one step forward.
That act requires feedback from and instructions to some 200 muscles, and it engages brain power that surpasses the mental activity involved in reasoning.
Taking a step is possible because of your sense of kinesthesia, which keeps you aware of your body parts.
You have millions of position and motion sensors all over your body.
The sensors give feedback to your brain.
Your brain gets an immediate update if you twist your wrist one degree.
Imagine being without sight and sound.
You can experience the dark silence by closing your eyes and plugging your ears.
Ian is from Hampshire, England.
In 1972, at the age of 19, he contracted a rare viral infection that destroyed his nerves and caused him to lose his sense of touch and movement.
People with this condition feel like their body is dead, not real, not theirs.
With a lot of practice, Waterman was able to walk and eat by looking at his limbs.
He would crumple to the floor if the lights went out.
Each of these high school competitive cheer team members can thank her inner ears for the information that helps her monitor her body's position.
Close your eyes and try again.
Your inner ear contains two structures that help you sense equilibrium.
Nerve signals from the back of your brain are sent when your head rotates or tilts, allowing you to sense your body position and maintain your balance.
If you twirl around and then stop, the fluid in your canals will not return to their neutral state.
The sensation that you're still spinning is caused by the dizzy aftereffect.
Under special conditions, mechanisms that normally give us an accurate experience of the world can fool us.
Clues to how our perceptual system works are provided by understanding how we get fooled.
ANSWER: Our joints, muscles, and tendons have kinesthetic receptors.
Our inner ear contains vestibular sense receptors.
There is a little known fact about your sense of hearing.
If you slip, your sensors will instantly order your response and you won't have time to think about how to right yourself.
Hold one of your thumbs in front of your face and move it quickly to the left and back.
Your vision isn't fast enough to notice how your thumb blurs.
Hold your thumb still and move your head from left to right.
Your head position is monitored by your vestibular system, which moves the eyes quickly.
Head and eyes move in opposite directions.
Vision is fast, but the sense of hearing is slower.
We've seen that vision and kinesthesia interact.
None of our senses act alone.
Our brain blends our senses' inputs to make sense of the world.
One sense can affect another.
Consider how smell affects taste.
Hold your nose, close your eyes, and 888-276-5932 888-276-5932 888-276-5932 888-276-5932s to 888-276-5932s to 888-276-5932s to 888-276-5932s to 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932 888-276-5932 888-276-5932s to 888-276-5932 888-276-5932 A piece of apple may be different from a piece of potato.
A piece of steak may not taste right.
A cup of coffee with no smell may be hard to distinguish from a glass of wine.
There is a big part of taste under your nose.
To savor a taste, we breathe the aroma through our nose.
Food molecule rise into our nose like smoke in a chimney.
Food tastes bland when you have a cold.
A drink's strawberry odor enhances our perception of its sweet taste.
Our taste can be influenced by touch.
A potato chip can taste fresh or old.
Maybe you have noticed that flavor is located in the mouth, not the nose.
Hearing may interact with vision.
When accompanied by a short burst of sound, a weak flicker of light becomes more visible.
Soft sounds can be heard more easily if they are accompanied by a visual cue.
If I watch a video with an on-screen caption, I can hear the words I am seeing.
If I decide I don't need the caption and turn them off, I will quickly realize I need them.
The ears are guided by the eyes.
Seeing the speaker form the words makes them easier to understand for hard of hearing people.
Our senses interact.
Our brain can perceive a third sound that blends both inputs.
Lip reading is a part of hearing.
Our bottom-up sensations and our top-down cognitions are the main ingredients in our perception.
sensation and perception are two points on a continuum.
It's not surprising that the brain circuits that process physical sensations interact with the brain circuits that process cognitive functions.
embodied cognitive is the result.
We think from the inside out.
People were more likely to rate someone more warmly, feel closer to them, and behave more generously after holding a warm drink rather than a cold one.
Jose is the warmer brother if you have hot tea with him and iced tea with Juan.
People judged the room to be colder than those who had been treated warmly after being given the cold shoulder.
Sitting at a wobbly desk and chair makes others' relationships seem less stable.
Our brain blends inputs from multiple channels as we attempt to understand our world.
Early in life, "exuberant neural connection" produces some associations among the senses, which later are normally--but not always--pruned.
Hearing music can cause a sensation of color in the cortex.
The number 3 may evoke a taste or color sensation.
TABLE 6.3 has a summary of our sensory systems.
The river of perception is fed by sensations.
More than half of Americans agree there are.
If ESP is true, we need to overturn the scientific understanding that our minds are tied to our physical brains and that our perceptual experiences of the world are built of sensations.
Research psychologists and scientists don't believe in supernatural phenomena.
In several universities, researchers perform scientific experiments looking for ESP phenomena.
Let's consider some popular beliefs before we see how they conduct their research.
The forecasts of "leading psychics" reveal meager accuracy, although one might wish for a psychic stock forecaster.
The tabloid psychics were wrong in their predictions.
The psychics missed some big news events.
Imagine their surprise when all 33 miners were rescued.
After her daughter went missing in Cleveland in 2003 her mother turned to a famous TV psychic for answers.
"She's not alive, honey," the psychic told the mom, who died without living to see her daughter rescued.
This result brought that psychic's record on 116 missing person and death cases to 83 unknown outcomes, 33 incorrect, and zero mostly correct.
Psychic visions offered to police departments have not been more accurate than guesses made by others.
Their volume increases the odds of an occasional correct guess, which psychics can report to the media.
Such visions can sound correct later on.
The Harvard psychologists invited people to report their dreams about the child after he was kidnapped and murdered in 1932.
The number was no better than chance, but the accuracy of their apparent precognitions must have been very good.
Some stunning coincidences are bound to occur because of the many events in the world each day.
Someone on Earth will think of another person more than a thousand times a day and then, within five minutes, learn of that person's death.
We should give chance when explaining an event.
So much better for the ideas if they do.
If they don't, that's great for our skepticism.
Both believers and skeptics agree that parapsychology needs a theory to explain it.
The image of parapsychology that comes to my mind, based on nearly 44 years in the field, is that of a small airplane that has been taxiing down the runway of the Empirical Science Airport since 1882.
A "mind machine" was created to see if people could influence or predict a coin toss.
Visitors to British festivals were given four tries to call heads or tails against a computer that kept score.
By the time the experiment ended, almost 30,000 people had predicted more than 100,000 tosses.
The experimenter controls what the "psychic" sees and hears.
"A psychic is an actor playing the role of a psychic" was the comment of a respected social psychologist.
Nine experiments that seemed to show people anticipating future events renewed hopes for replicable evidence of ESP.
When an erotic scene was about to appear on a screen in one of two randomly selected positions, Cornell University participants guessed the right placement 53.1 percent of the time, beating 50 percent by a small but statistically significant margin.
Bem wondered if his findings showed an evolutionary advantage to those who can anticipate future dangers.
Critics were not impressed despite the paper having survived critical reviews.
Some found the methods "badly flawed" or the statistical analyses "biased".
The results could not be replicated by "independent and skeptical researchers" according to others.
One cognitive scientist wrote that if any of his claims were true, then all of the bases underlying contemporary science would have to be reexamined.
Bem has made his research materials available to anyone who wants to copy his work.
Multiple attempts have met with little success and controversy.
It has been willing to challenge its assumptions.
The validity of that finding has been assessed through follow-up research.
Science sifts crazy-sounding ideas, leaving most on the historical waste heap while occasionally surprising us.
James Randi offered $1 million to anyone who proved a genuine psychic power under proper observing conditions.
French, Australian, and Indian groups have made similar offers.
The scientific seal of approval would be worth a lot more.
One needs only a single person who can demonstrate an ESP event to refute those who say there is no ESP.
No such person has shown up so far.
The ESP event needs to be reproduced in other scientific studies.
To feel awe, mystery, and a deep reverence for life, we need look no further than our own perceptual system and its capacity for organizing formless nerve impulses into colorful sights, vivid sounds, and evocative smells.
Much more than has been dreamt of in our psychology lies within our ordinary sensory and perceptual experiences.

According to research, trying to answer these questions on your own will improve retention.
The inner ear has a tube that converts sound waves into neural activity.
The __________ theory explains how we hear high-pitched sounds.
The skin's sensory receptors are found mostly in the skin and are called ___________.
The gate-control theory of pain suggests that pain signals are sent to the brain.
Your sense of body position and movement is what it is.
Your head's movement is monitored with sensors in the inner ear.
A food's smell can make it taste better.
This is an example of disloyalty.
You can find answers in the e-book and at the back of the printed text.
The power of a new learning technology was witnessed by University of Minnesota graduate students Marian and Keller Breland.
The behavior of cats, chickens, parakeets, turkeys, pigs, ducks, and hamsters was shaped by the Brelands after they were impressed by Skinner's results.
They spent the next half century training more than 15,000 animals from 140 species for everything from movies to amusement parks.
Amy wondered if shaping had uses closer to home while writing about animal trainers.
The same techniques could be used to train elephants and baboons to skateboard.
She trained her husband to find out.
She was thanking Scott if he threw a dirty shirt into the hamper.
We learn from our experience.
We can learn how to adapt to almost any environment by building grass huts, snow shelters, submarines or space stations.
Learning leads to hope.
A fact that encourages parents, educators, coaches, and animal trainers is what is learnable.
An assumption that underlies counseling, psychotherapy, and rehabilitation programs can be changed by new learning.
Even if we are unhappy or unsuccessful, that doesn't mean our story is over.
The learning of visual perception, of a drug's expected effect, and of gender roles were considered in earlier chapters.
We will see how learning shapes us in the later chapters.
Classical conditioning, operant conditioning, the effects of biology and cognition on learning, and learning by observation are examined in this chapter.
Humans learn by adapting to our environments.
The events that occur in sequence are connected by our minds.
If you see and smell freshly baked bread, you will find it satisfying.
When you smell fresh bread, you will expect to eat it again.
Hearing the sound alone may make you fear it.
If you give people a red pen instead of a black pen, they will spot more errors and give lower grades.
People are more likely to support taxes for education if they vote in a school.
Habitual behaviors are also fed by learned associations.
When we repeat behaviors in a given context, we can form habits.
Our next experience of that context will evoke our response as behavior becomes linked with it.
When we're mentally fatigued, we tend to fall back on our habits.
Good and bad habits are related (Graybiel & Smith, 2014).
To increase our self-control, and to connect our resolutions with positive outcomes, the key is forming beneficial habits.
To find out, one British research team asked 96 university students to choose some healthy behavior, such as running before dinner or eating fruit with lunch, to do it daily for 84 days, and to record whether the behavior felt automatic.
After about 66 days, behaviors become habit.
If you just do it every day for two months or more, you will find yourself with a new habit.
It happened for both of us, with a midday workout or late afternoon run.
Other animals learn from each other.
The withdrawal response will diminish if the squirts continue.
The sea slug's protective response to squirts grows stronger if it receives an electric shock repeatedly.
The squirt is associated with the impending shock by the animal.
Complex animals can associate their behavior with their outcomes.
A seal in an aquarium will repeat behaviors that prompt people to toss it a herring.
The seal slaps and barks with a herring treat while the sea slugs associate the squirt with an impending shock.
The animals have learned to anticipate the immediate future.
The events can be two stimuli or a response and its consequence.
When lightning strikes close to us, we start to feel a crack of thunder.
We respond to stimuli that we don't control.
We learn to repeat acts after good results and avoid acts after bad results.
Operant behaviors operate on the environment to produce a consequence.
Most of us can't remember the order of the songs on our favorite album.
Hearing the end of one piece cues is an anticipation of the next.
When singing your national anthem, you associate the end of each line with the beginning of the next.
We will explore the two types of associative learning separately.
On a Japanese cattle ranch, a clever rancher fitted his herd with electronic pagers, which he called from his cell phone.
After a week of training, the animals learned to associate two stimuli--the beep of their pager and the arrival of food.
They learned to associate hustling to the food trough with the pleasure of eating, which simplified the rancher's work.
There are other forms of learning.
We acquire mental information through cognitive learning.
Chimpanzees learn behaviors by watching others do them.
The observer may perform the trick more quickly if one animal sees another solve a puzzle and get a food reward.
We look and we learn.
Classical conditioning is something we should look more closely at.
When we repeat behaviors in a given context, we learn associations and form habits.
The name Ivan Pavlov is associated with many people.
's work was based on the work of Pavlov.
The theoretical goal of psychology is to study how organisms respond to stimuli in their environments.
Psychology should be an objective science based on observable behavior.
During the first half of the twentieth century, behaviorism influenced North American psychology.
The basic laws of learning were the same for all animals, even if they had different "mentalistic" concepts.
Most researchers agree that classical conditioning is a basic form of learning and that psychology should ignore mental processes.
Most research psychologists don't agree with two things.
"Experimental investigation should lay a solid foundation for a future true science of psychology"
A lifelong passion for research drove Pavlov.
After setting aside his initial plan to follow in his father's footsteps into the Russian Orthodox priesthood, Pavlov earned a medical degree at age 33 and spent the next two decades studying the digestive system.
This work earned him a prize.
His novel experiments on learning, which consumed the last three decades of his life, earned this feisty, intense scientist his place in history.
