Explain how very high and very low intelligence is defined and what it means to have them. Define stereotype threat and explain how it might influence scores on intelligence tests. Most people in Western cultures tend to agree with the idea that intelligence is an important personality variable that should be admired in those who have it. But people from Eastern cultures tend to place less emphasis on individual intelligence and are more likely to view intelligence as reflecting wisdom and the desire to improve the society as a whole rather than only themselves (Baral & Das, 2004; Sternberg,  2007). And in some cultures, such as the United States, it is seen as unfair and prejudicial to argue, even at a scholarly conference, that men and women might have different abilities in domains such as math and science and that these differences might be caused by genetics (even though, as we have seen, a great deal of intelligence is determined by genetics). In short, although psychological tests accurately measure intelligence, it is cultures that interpret the meanings of those tests and determine how people with differing levels of intelligence are treated. In a normal distribution, the bulk of the scores fall toward the middle, with many fewer scores falling at the extremes. These sex differences mean that about 20% more men than women fall in the extreme (very smart or very dull) ends of the distribution (Johnson,  Carothers, & Deary, 2009). Boys are about five times more likely to be diagnosed with the  reading disability dyslexia than are girls (Halpern, 1992), and are also more likely to be classified as mentally retarded. About 1% of the United States population, most of them males, fulfill the criteria for mental retardation, but some children who are diagnosed as mentally retarded lose the classification as they get older and better learn to function in society. Mental retardation is divided into four categories: mild, moderate, severe, and profound. One cause of mental retardation is Down syndrome, a chromosomal disorder leading to mental retardation caused by the presence of all or part of an extra 21st chromosome. The incidence of Down syndrome is estimated at 1 per 800 to 1,000 births, although its prevalence rises sharply in those born to older mothers. People with Down syndrome typically exhibit a distinctive pattern of physical features, including a flat nose, upwardly slanted eyes, a protruding tongue, and a short neck. Societal attitudes toward individuals with mental retardation have changed over the past decades. We no longer use terms such as “moron,‖ “idiot,‖ or “imbecile‖ to describe these people, although these were the official psychological terms used to describe degrees of retardation in the past.

The original issue usually quite reserved and shies away from public that came up was that the nurse was very concerned forums, with encouragement she was able to share that the doctor on the interdisciplinary team, who the experience with this patient in a large public was also the patient’s therapist, was not giving the forum. She not only shared with other profession- patient the support that the nurse felt the patient als the role that she as a nurse played in the treat- was calling out for. This nurse and I explored her ment of this patient, but she also acknowledged perception that the patient did in fact seem to be herself in a group of professionals as a “knowing reaching out. The patient was told Patients call to us both verbally and nonverbally, that there were treatments to retard the disease but with all sorts of health-related needs. Given this, the doctor, tant to hear the calls and know the process that lets whose primary function is treatment and cure, was us understand them.

An important binocular depth cue is convergence arcoxia 60mg, the inward turning of our eyes that is required to focus on objects that are less than about 50 feet away from us 60mg arcoxia with amex. The visual cortex uses the size of the convergence angle between the eyes to judge the object’s distance order 120 mg arcoxia with mastercard. You will be able to feel your eyes converging if you slowly bring a finger closer to your nose while continuing to focus on it. When you close one eye, you no longer feel the tension—convergence is a binocular depth cue that requires both eyes to work. As the lens changes its curvature to focus on distant or close objects, information relayed from the muscles attached to the lens helps us determine an object’s distance. Accommodation is only effective at short viewing distances, however, so while it comes in handy when threading a needle or tying shoelaces, it is far less effective when driving or playing sports. Monocular depth cues are depth cues that help us perceive depth using  only one eye (Sekuler & Blake, 2006). Assuming that the objects in a scene are At right, the cars in the same size, smaller the distance appear objects are perceived smaller than those Relative size as farther away. When they appear closer together, we Linear Parallel lines appear to determine they are perspective converge at a distance. At right, because the When one object blue star covers the overlaps another pink bar, it is seen as object, we view it as closer than the Interposition closer. Perceiving Motion Many animals, including human beings, have very sophisticated perceptual skills that allow them to coordinate their own motion with the motion of moving objects in order to create a collision with that object. Bats and birds use this mechanism to catch up with prey, dogs use it to catch a Frisbee, and humans use it to catch a moving football. The brain detects motion partly from the changing size of an image on the retina (objects that look bigger are usually closer to us) and in part from the relative brightness of objects. The beta effect refers to the perception of motion that occurs when different images are presented next to each other in succession (see Note 4. The visual cortex fills in the missing part of the motion and we see the object moving. A related effect is thephi phenomenon, in which we perceive a sensation of motion caused by the appearance and disappearance of objects that are near each other. The phi phenomenon looks like a moving zone or cloud of background color surrounding the flashing objects. The beta effect and the phi phenomenon are other examples of the importance of the gestalt—our tendency to “see more than the sum of the parts. In the phi phenomenon, the perception of motion is based on the momentary hiding of an image. The lens adjusts to focus the light on the retina, where it appears upside down and backward. Receptor cells on the retina are excited or inhibited by the light and send information to the visual cortex through the optic nerve. Color blindness occurs when people lack function in the red- or green- sensitive cones. Consider some ways that the processes of visual perception help you engage in an everyday activity, such as driving a car or riding a bicycle. Do you think you would be able to compensate for your loss of sight by using other senses? Segregation of form, color, movement, and depth: Anatomy, physiology, and perception.
Sex and Weight Alcohol is highly hydrophilic buy arcoxia 60 mg lowest price, so once it enters the systemic circulation buy cheap arcoxia 60 mg line, it is distributed evenly throughout total body water (Vd 60mg arcoxia sale, or the volume of dis- tribution). In general, the larger the person the larger the Vd, so that if two different sized males drink the same quantity of alcohol, a higher peak con- centration will be reached in the lighter of the two because he will have a smaller Vd for the alcohol to distribute itself throughout. Similarly, because 308 Stark and Norfolk women have more body fat compared with men, and fat contains no water, higher peak alcohol levels are achieved in women than in men of the same weight. Duration of Drinking If a volume of alcohol is consumed over a prolonged period, it may be eliminated almost as quickly as it is absorbed, giving rise to a much lower peak alcohol concentration. Nature of the Drink Consumed The rate of alcohol absorption increases with the concentration of the ingested solution to levels between 10 and 20%, at which point absorption is maximal. Because alcohol is absorbed by passive diffusion, the rate of ab- sorption is slower with drinks of lesser strength because of a lower concentra- tion gradient. Furthermore, the larger volumes involved may also delay gastric emptying and further slow absorption. By contrast, when the alcohol concen- tration of drinks exceeds 20%, the alcohol irritates the gastric mucosa and pyloric sphincter, causing increased secretion of mucus and delayed gastric emptying, thus slowing absorption. Food in the Stomach Studies have shown that eating a full meal before drinking can reduce the peak alcohol level by an average of 9–23% (129,136–138). The presence of food in the stomach reduces the rate of gastric emptying, dilutes the alcohol that enters the stomach, and limits the contact between the alcohol and the gastric mucosa. Physiological Factors and Genetic Variation Factors, such as stomach wall permeability, blood supply to the alimen- tary tract, and the rate of gastric emptying, vary from person to person and from time to time in the same person. Drugs The interaction between alcohol and drugs, either prescribed or illicit, is important because many detainees take other drugs in conjunction with alco- hol (2). Substance Misuse 309 Table 14 Drugs That Affect the Rate of Stomach Emptying and So Influence the Rate of Alcohol Absorption • Drugs that slow gastric emptying: Drugs with anticholinergic actions, such as: atropine; chlorpromazine; tricyclic antidepressants Drugs with an adrenergic action, such as: amphetamines Drugs with an opioid action, such as: antidiarrheal medicines; codeine and dihydrocodeine; diamorphine (heroin); methadone; dextropropoxyphene (in co-proxamol) • Drugs that hasten stomach emptying, such as: metoclopramide; cisapride; erythromycin Adapted from ref. However, several drugs may influence the rate of alcohol absorption by virtue of their affect on the rate of gastric emptying (Table 14). Rate of Elimination The rate of elimination of alcohol has been determined experimentally. Reported values range from approx 10 mg/100 mL of blood per hour (mg/dL/h) to 25 mg/dL/h, with an average of 15–18. Ha- bituation to alcohol is the single most important factor affecting the rate of elimi- nation. One recent study reported the rate of ethanol disappearance in 22 alcoholics as ranging from 13 to 36 mg/dL/h, with an average of 22 mg/dL/h (140). The increased rate of elimination is believed to be because chronic alco- holics have facilitated liver enzyme systems. The apparent stimulatory effects of alcohol occur because it acts first on the so-called higher centers of the brain that govern inhibition (141). Although there is general agreement on the sequence of clinical effects caused by drinking alcohol, the blood alcohol concentrations at which these effects occur vary in different subjects. The difference in susceptibility is most marked between habituated and nonhabituated drinkers, but tolerance to the effects remains variable even within these broad categories (142,143). It should be noted that the effects are more pronounced when blood alcohol levels are rising than when falling. This is known as the Mellanby effect and is believed to result from an acute tolerance to alcohol that develops during intoxication (144). An angle of onset of 40° or less from the midline is a sensitive indicator of a blood alcohol level in excess of 100 mg/100 mL (143). Pupillary Changes In the early stages of alcoholic intoxication the pupils are said to dilate, often becoming pinpoint as the level of intoxication advances, particularly when the state of coma is reached (154). However, some commentators report the pupils as being normal-sized in alcohol intoxication (155), with current advice favoring the view that pupil size may be normal or dilated (156).
Do not cover with any type of petroleum-based cream or butter purchase 60mg arcoxia mastercard, as they retain heat order arcoxia 90mg, slow healing 90mg arcoxia sale, and in- crease risk of infection. Honey products are also available in a spray, salve, or tincture (The British Journal of Surgery, 1991: 78; 497–498). Top Recommended Treatments Aloe vera gel: Cooling, helps relieve pain and inﬂammation, and also has anti-inﬂammatory properties. It is commonly used to manage burns and has a long history of use to promote wound healing, although the scientiﬁc research is lacking. Use aloe vera from a plant (split open a leaf) or get pure aloe gel at a health food store or pharmacy. Antioxidants: Studies have shown that oral supplements of vitamins A, C, E, zinc, and selenium can help to protect the skin from sunburn due to free radical-producing ultravio- let rays. Topical vitamin E cream or oil is commonly used to promote skin healing and may reduce scarring. Complementary Treatments Calendula cream: Soothing, has anti-inﬂammatory properties, and may help promote tissue repair. After a burn has cooled, cleanse with chamomile B tea and apply fresh aloe vera gel. Eat a healthy diet packed with lots of fresh fruits and vegetables, whole grains, and ﬁsh. Increase total calorie intake during the healing process and drink lots of liquids. It is the leading cause of premature death in Canada—about 1,006,000 potential years were lost in 2003 as a result of cancer. Cancer has become an age-related phenomenon: 44 percent of new cancer cases and 60 percent of cancer deaths will occur among those who are at least 70 years old. Rather, in many cases it is generally thought that our lifetime exposure to factors that increase our risk, such as smoking or eating a poor diet, leads to the development of cancer. Our bodies are made up of millions of cells grouped together to form tissues or organs, such as muscles, skin, bones, and organs. Cancer occurs when there is an abnormal growth of cells, which can form lumps or tumours, or can spread through the bloodstream and lymphatic system to other parts of the body. Benign tumour cells stay in one place in the body and are not usually life-threatening. Malignant tumour cells are able to spread to invade nearby tissues and other parts of the body, which is a process called metastasis. Finding cancer early and getting treat- ment before it spreads can greatly help improve your chances of survival. While we think of cancer as one disease, it is actually a group of more than 100 different diseases. It can involve any tissue of the body and have many different forms in each body area. The four most common types of cancer in Canada are breast, prostate, lung, and colon. A great deal of research has focused on the underlying causes of abnormal cell growth. We do know that certain factors, such as free radical damage, genetics, diet, and lifestyle, are involved. While many of us may blame our family history, only about 5–10 percent of cancers are attributed to faulty genes. Having a family history may increase your risk of certain cancers, but researchers feel that whether or not those genes are “switched on” may depend largely on lifestyle and environment. These critical yet often overlooked factors play a role not only in prevention but also in the treatment and recovery from cancer.
