Critical Thinking Questions
26. Not everything that is sensed is perceived. Do you think there could ever be a case where something could be perceived without being sensed?
27. Please generate a novel example of how just noticeable difference can change as a function of stimulus intensity.
28. Why do you think other species have such different ranges of sensitivity for both visual and auditory stimuli compared to humans?
29. Why do you think humans are especially sensitive to sounds with frequencies that fall in the middle portion of the audible range?
30. Compare the two theories of colour perception. Are they completely different?
31. Colour is not a physical property of our environment. What function (if any) do you think colour vision serves?
32. Given what you’ve read about sound localization, from an evolutionary perspective, how does sound localization facilitate survival?
33. How can temporal and place theories both be used to explain our ability to perceive the pitch of sound waves with frequencies up to 4000 Hz?
34. Many people experience nausea while traveling in a car, plane, or boat. How might you explain this as a function of sensory interaction?
