The activation of the sense organs by a source of physical energy is known as . A. perception B. sensation C. integration D. interpretation 3. The sorting out, interpretation, analysis, and integration of stimuli by the sense organsand brain is known as _ _. A. perception B. sensation C. activation D. stimulation 4. Which of the following statements is TRUE of sensation and perception? A. Perception generally precedes sensation in our processing of a stimulus. B. Sensation and perception are essentially synonyms. C. Sensation involves the interpretation of a stimulus, whereas perception does not. D. Sensation involves the activation of sense receptors; perception involves interpretation. 5. The study of the relationship between the physical aspects of stimuli and our psychological experience of them is known as . A. developmental psychology B. thermodynamics C. psychophysics D. experimental psychology 6. Dr. Breiland examines the relationship between the physical properties of light, such asits amplitude and wavelength, and humans’ perception of color. Which of the following terms MOST ACCURATELY describes Dr. Breiland’s field of study? A. Developmental psychology B. Psychophysics C. Thermodynamics D. Experimental psychology 7. A(n) _ _ is the smallest intensity of a stimulus that must be present for the stimulus tobe detected. A. difference threshold B. absolute threshold C. adaptation threshold D. intensity threshold 8. A(n) _ _ threshold is the stimulus intensity that is detected 50% of the time. A. difference B. absolute C. adaptation D. frequency 9. One can detect a single drop of perfume diffused in an area the size of a one-bedroom apartment. This is due to: A. absolute threshold. B. difference threshold. C. adaptation threshold. D. psychophysical minimum. 10. Which of the following most closely approximates the meaning of the term noise as psychophysicists use it? A. Only unwanted stimuli B. An unpleasant sound C. Any distraction D. Only auditory stimuli 11. The smallest level of added or reduced stimulation required to sense that a change in stimulation has occurred is known as the _. A. difference threshold B. absolute threshold C. adaptation threshold D. intensity threshold 12. A snack manufacturer realizes that he must increase the salt content of his company’schips by 3% in order for a sample of consumers to notice that the chips are saltier than they were before. This example most nearly illustrates the concept of a(n): A. absolute threshold. B. difference threshold. C. frequency threshold. D. adaptation threshold. 13. Weber’s law states that a just noticeable difference is a . A. fixed value B. constant proportion of the intensity of an initial stimulus C. variable proportion of the intensity of an initial stimulus D. random value 14. Acme Foods wants to make its chips saltier, but it doesn’t want to spend more than ithas to on salt. A sample of consumers are asked to compare its current chip (saltiness = 100) with saltierversions and to say whether the new version is saltier. On average, sample consumers reliably say the newchip is saltier when its saltiness value is 108, but not when its saltiness value is below 108. AssumingAcme Foods’ sample consumers are representative of people in general, which of the following best represents the just noticeable difference for saltiness? A. 8% B. 108 C. 80% D. 100 15. _ is a basic law of psychophysics stating that a just noticeable difference is a constant proportion to the intensity of an initial stimulus. A. Fitt’s law B. Weber’s law C. Bloch’s law D. Hick’s law
