Psych exams 05 02 2013 Endorphins are neurotransmitters I read an article showing a positive relationship between exercise and heart disease I say it is wrong because my uncle ran three miles a day and died of a heart attack My thinking is an example of person who phenomenon The symmetrical bell shaped figure used to represent the distribution of many physical and psychological characteristics is called a normal curve The hindsight bias refers to people s tendency to exaggerate their ability to have foreseen an outcome Professor ober carefully observes and records the behaviors of children in their classrooms in order to track the development of their social and intellectual skills Professor ober is most clearly engaged in naturalistic observation Assessing whether conclusions are warranted by the existing evidence best illustrates critical thinking Under what conditions can you correctly infer causality from a correlation Casualty should not be inferred from a correlation Dr wolski conducts research on the potential relationship between neurotransmitter deficiencies and mood states the biological perspective Procedures by which subjects were given the list of 50 words to remember and then later asked to recall them is the operational definition of memory A negative correlation between degree of wealth and likelihood of suffering from a psychological disorder would indicate that people who are poor are more likely to have a psychological disorder than are wealthy people A statement describing the exact procedures for measuring a variable is known as an operational definition In the discussion of nature nurture nurture refers to the effects of environment on behavior In Thorndike s experiment with the puzzle box the dependent variable was how long it took the cat to escape from the puzzle box In an experimental study men with erectile dysfunction received either Viagra or a placebo In this study the drug dosage was the independent variable When every individual in a large population has a small but equal chance of being included in a survey random sampling Which technique involves repeating the essence of an earlier research study with different participants and in different circumstances replication Contemporary psychology is best defined as the science of behavior and mental processes A synapse is a junction between a sending neuron and a receiving neuron An axon is the extension of a neuron that carries messages away from the cell body Surveys measure what people say not what they do The depolarization of a neural membrane can create a action potential Psychologists do not use sophisticated statistical techniques has not been suggested as an obstacle to the scientific study of behavior The longest part of a motor neuron is likely to be the axon Action potential is generated by the movement of ions Neurotransmitters are released from vesicles located on knoblike terminals at the end of axons The psychologist was interested in testing the effect of independent on dependent In transmitting sensory information to the brain an electrical signal travels from the dendrites to the cell body to the axon of a single neuron An inert substance that may be administered instead of a drug to see if it procedures any of the same effects as the drug is called a placebo The time taken to response to a touch on the hand should be longer than the time taken to respond to a touch on the shoulder because of the speed of conduction of nerve impulses Neural stimulation that exceeds a threshold triggers an action potential According to the all or none response law neurons fire with their full potential or not at all Correlational research is most helpful for clarifying cause effect relationships Phrenology highlight the presumed functions of specific brain regions To determine whether the strength of people s self esteem is related to their income levels researches would most likely make use of correlational research 05 02 2013 Picture of dog left picture of boy right patient would verbally report she saw a boy Only disliked if they had been told they were drinking vinegar beer perceptual set Practical implications of theories of pitch perception how cochlear implants are designed In viewing the ambiguous picture of the cow the image on the screen was bottom up stimulus and the hints about it being a farm animal was engaged top down processes Retinal disparity is an important cue for perceiving distance People s moral judgments are most likely to seem unrestrained by normal emotions if they have suffered damage to their frontal cortex A psychophysicist would be most directly be concerned with the relationship between the wavelength of light and the experience of color According to the book and lecture there are 3 types of color receptors wired up in an opponent process You would not expect to see inability to see fine detail in individuals born without functioning rods In addition to coordinating voluntary movement the cerebellum enables nonverbal learning and memory Infants exposed to the visual cliff refused to cross over into the glass over the cliff to their mothers Auditory stimulation is first processed in the temporal lobes Semicircular canals dizziness Damage to the fovea would probably have the least effect on visual sensitivity to dimly illuminated stimuli Having trouble forming new memories involves the hippocampus Damage to the hammer anvil and stirrup would most likely cause conduction hearing loss High frequency hearing loss pitch place Blues generally appear brighter than reds because rods are more sensitive to short wavelengths of light Damage to the left cerebral hemisphere is most likely to reduce people s ability to solve arithmetic problems The amount of light entering the eye is regulated by the iris Losing hearing because of high amplitude sounds is due to problems in the cochlea Patients who have negative expectations about the outcome of a surgical procedure may experience increased postoperative pain top down processing Central nervous system neurons that process information between sensory inputs and motor outputs are called interneurons Perceived size of an object is most strongly influenced by that objects perceived distance A radioactive form of glucose to tell which areas of brain are active during speech is pet scan The high notes on a piano always produce higher frequency sound waves than low notes Some combination of place theory and frequency theory appears to be
