PSYC 102 Quiz 1 Assessment 2026: Already Answered and A+ Graded 1. Psychology is defined as the ____ - ANSWER scientific study of behavior and mental processes 2. When psychologists conduct research through a systematic process of testing ideas about behavior, they are using ________. - ANSWER the scientific method 3. A psychologist's explanation of a particular behavior is generally presented as a(n) ____ - ANSWER theory 4. Transmitting info to a neuron - ANSWER 1) dendrites receive information from another neuron 2) information is collected and integrated in the cell body 3) information is sent down the axon as an action potential 4) AP makes its way to the synapses where the information is sent out as neurotransmitters 5. Divisions of the Nervous System - ANSWER 1) central nervous system: part of the nervous system that consists of the brain and the spinal cord 2) peripheral nervous system: part of the nervous system that enables nerves to connect the central nervous system to the muscles, organs, and glands 6. Theories of Color Vision - ANSWER 1) trichromatic: relates color perception to cone receptors. color perception results from activity across three different types of cone receptors 2) opponent process: explanation of perceptual after images (green to red, yellow to blue) 7. Stages of Sleep - ANSWER Stage one: begins when sleepers drift off, shown on the EEG as theta waves Stage two: breathing becomes more regular and sleepers become less sensitive to external stimulation (k-complexes) Stage three and four: slow wave sleep. deep sleep, when EEGs reveal large, regular delta waves and sleepers are hard to wake up. 8. Sleeping Disorders - ANSWER 1) insomnia: inability to fall asleep or to stay asleep. 12-20% of adults have insomnia. more common in women and older adults. 2) sleep apnea: the throat closes and breathing stops; results in frequent awakenings during the night 3) narcolepsy: a person experiences excessive sleepiness during normal waking hours 9. Theories of Dreaming - ANSWER 1) activation-synthesis: dreams are the result of the brains attempts to make sense of random brain activity by synthesizing the activity with stored memories 2) dreams-for-survival: suggests that dreams permit information that is critical for our daily survival to be considered and repressed during sleep 10. _____________ was the founding father of psychology and set up the first psych laboratory. - ANSWER Wilhelm Wundt 11. Communication is transferred between neuron at the ______________ where neurotransmitters are secreted. - ANSWER Synapse 12. Descriptive Research - ANSWER a research method that provides a systematic and objective description of what is occurring 13. Experimental Research - ANSWER research methods that test causal hypotheses by manipulating independent variables and measuring the effects of dependent variables 14. Control Group - ANSWER a comparison group of participants who receive no intervention or receive intervention that is unrelated to the independent variable being investigated 15. Experimental Group - ANSWER one or more treatment groups of participants who receive the intervention of the independent variable being investigated 16. Positive Correlation - ANSWER if one variable increases, the other variable increases. if one decreases, the other decreases 17. Negative Correlation - ANSWER if one variable increases, the other variable decreases and vice versa 18. Mirror Neurons - ANSWER type of brain cells that respond equally when we perform an action and when we witness someone else perform the same action 19. Neurotransmitters - ANSWER chemical substances that carry signals from one neuron to another 20. Monocular Cues - ANSWER cues of depth perception that are available to each eye alone 21. Perceptual Constancy - ANSWER physical objects are perceived as unvarying and consistent despite changes in appearance or changes in the physical environment 22. Binocular Disparity - ANSWER we use both eyes to perceive depth through binocular disparity, where each retina has a slightly different view of the world *pencil example* 23. Olfaction - ANSWER sense of smell 24. Gustation - ANSWER sense of taste 25. Absolute Threshold - ANSWER smallest amount of physical stimulation required to detect a sensory input half of the time it is present 26. Difference Threshold - ANSWER minimum difference in physical stimulation required to detect a difference between sensory inputs 27. Webers Law - ANSWER law that quantifies the perception of change in a given stimulus; change in stimulus that will be noticeable is a constant ratio of the original stimulus 28. REM - ANSWER rapid eye movement, dreaming, paralysis of motor systems, 20% of sleep cycle, increased heart rate, blood pressure, and breathing 29. Tolerance - ANSWER when someone has to take more of a drug to get the same effect
