Psychology – Gleitman

Psychology Gleitman Blood flow in the brain during different activities: the rate of blood flow is measured by special radiation counters that are placed at various points of the skull and that monitor radiation from mildly radioactive gas injected into the bloodstream. Blood flow pattern depends on what the patient does ( different pattern is found when person is reading aloud, yet another when he watches a moving light and so on). Ambiguous sights and sounds: The way ambiguous figures are perceived often depends on what we have seen just before. For example, if we are first shown an unambiguous figure of a rat, the ambiguous picture will be seen as a rat. If we are first exposed to an unambiguous face, we see the ambiguous figure as a face. What holds for visual patterns also holds for language. Many utterances are ambiguous. If presented out of context, they can be undestrood in several different ways. For example, ,,The mayor ordered the police to stop drink

PSYCHOLOGY PART 1: CORE Biological level of analysis Outline principles that define the biological level of analysis. 1) Behavior can be innate, because it is genetically based. Evolution may play a key role in behavior. 2) Animals may be studied as a means of understanding human behavior. 3) There are biological correlates of behavior. Cognitions, emotions and behaviors are products of the anatomy and physiology of our nervous and endocrine system. Explain how principles of the biological level of analysis may be demonstrated in research. 1) Correlational studies: Study by Buss, who hypothesized that across cultures, men will prefer to marry younger women because of greater reproductive capacity and women will place greater value on a potential mate's earning potential to provide survival advantages. This evolutionary hypothesis was tested in 37 cultures by sending out questioners. 2) Twin studies (type of correlational stud

Caffeine

1 Caffeine 2 3 Caffeine (C8H10N4O2) is the common name for trimethylxanthine (systematic name is 1,3,7- 4 trimethylxanthine or 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione). The chemical is also 5 known as coffeine, theine, mateine, guaranine, or methyltheobromine. Caffeine is naturally 6 produced by several plants, including coffee beans, guarana, yerba maté, cacao beans, and tea. 7 For the plants, caffeine acts as a natural pesticide. It paralyzes and kills insects that attempt to 8 feed on the plants. The molecule was first isolated by the German chemist Friedrich Ferdinand 9 Runge in 1819. 10 When purified, caffeine is an intensely bitter white powder. It is added to colas and other soft 11 drinks to impart a pleasing bitter note. However, caffeine is also an addictive stimulant. In 12 humans, it stimulates the central nervous system, heart rate, and respiration, has psychotropic 13 (mood altering) p

Drugs and how they affect your health.

Drugs are chemicals that change the way a person's body works. You've probably heard that drugs are bad for you, but what does that mean and why are they bad? Medicines Are Legal Drugs If you've ever been sick and had to take medicine, you already know about one kind of drugs. Medicines are legal drugs, meaning doctors are allowed to prescribe them for patients, stores can sell them, and people are allowed to buy them. But it's not legal, or safe, for people to use these medicines any way they want. Cigarettes and Alcohol Cigarettes and alcohol are two other kinds of legal drugs. (In Estonia, adults 18 can buy cigarettes and alcohol.) But smoking and excessive drinking are not healthy for adults and off limits for kids. Nicotine is the drug in tobacco leaves. Whether someone smokes, chews, or sniffs tobacco, he or she is delivering nicotine to the brain. Each cigarette contains about 10 milligrams of nicotine. Nicotine is what keeps people smoking despite its harmful effects. Because t

Kordamisküsimused 1.prax: · Mis on rakuliin ja rakkude primaarkultuur, mille poolest erinevad? Primaarne rakukultuur on otseselt koest eraldatud rakkudest koosnev ja piiratud jagunemisvõimega kloon. Rakuliin on imortaliseeritud kloon, mis on võimeline paljunema/ jagunema piiramatult. Immortaliseeritud liine saab kas iseeneslike mutatsiooni tagajärjeliste transformatsioonide kaudu, ka eraldades rakke kasvajatest. Tekitada kunstlikult telomeraasi sisseviimisel rakku. Rakuliin sageli aneupolidne- kromosoomide arv normaalsest erinev (tavaliselt suurem). Eri rakutüübid transformeeruvad eri sagedusega, suured liikidevahelised erinevused. · Milleks on söötmesse lisatud seerum, antibiootikumid ja aminohapped? Et rakud end hästi tunneksid. Seerum-keskkond + mitogeenid=kasvufaktorid ja muud proliferisatsiooniks vajalikud substansid. Antibiootikumid-et bakterid vohama ei hakkaks, meie rakud olid antibiootikumile resistentsed (vist).
