Krause, Corts, Dolderman, Smith, Psychological Science, Canadian Edition, Chapter 4: Sensation and Perception 1) The terms sensation and perception have the same meaning and are interchangeable. a. True b. False Correct: Sensation and perception are different, yet integrated, processes. Answer: b Page Reference: 131 2) When measuring absolute threshold, reliable detection is said to occur when a person can detect a signal 99 percent of the time. a. True b. False Correct: Absolute threshold is the minimum amount of energy, or quantity of a stimulus, required for it to be reliably detected at least 50% of the time it is presented. Answer: b Page Reference: 134 3) The intensity or brightness of light corresponds to the amplitude of the light wave. a. True b. False Correct: Low amplitude waves correspond with dim colours, and high amplitude waves with bright colours. Answer: a Page Reference: 144 4) Dark adaptation is the process by which visual receptors become increasingly sensitive to dim light. a. True b. False Correct: Low amplitude waves correspond with dim colours, and high amplitude waves with bright colours. Answer: a Page Reference: 147 5) There are three basic types of cones in the retina, each of which responds maximally to a different wavelength. Copyright © 2015 Pearson Canada Inc.

False Correct: The trichromatic theory (or Young-Helmholtz theory) maintains that colour vision is determined by three different cone types that are sensitive to short, medium, and long wavelengths of light. Modern technology has been used to measure the amount of light that can be absorbed in cones and confirmed that each type responds to different wavelengths.
