Ester is walking to her chemistry class when she notices someone in the distance suddenly duck into a dark doorway. She is suspicious and starts to chase the figure, but misjudges the distance and accidentally runs into the door. She falls down but quickly recovers, and laughs when she discovers that the mystery person is her roommate, who was avoiding Ester, because she had borrowed Esters favorite sweater without permission and was afraid Ester might be angry. Use the following terms to explain the perceptual processes involved in this scenario. Gate-control theory Vestibular sense Selective attention Signal detection theory Binocular cues Perceptual set
Problem 21Ester is walking to her chemistry class when she notices someone in the distance suddenlyduck into a dark doorway. She is suspicious and starts to chase the figure, but misjudges thedistance and accidentally runs into the door. She falls down but quickly recovers, and laughswhen she discovers that the mystery person is her roommate, who was avoiding Ester, becauseshe had borrowed Ester's favorite sweater without permission and was afraid Ester might beangry. Use the following terms to explain the perceptual processes involved in this scenario.Gate-control theory Vestibular sense Selective attention Signal detection theoryBinocular cues Perceptual set Step-by-step solution-Gate-control theory: In this scenario, whether Ester feels pain from running into the door andfalling down depends on whether the pain gateways in her spine are “open” or “closed.” This willdepend on the severity of the pain signal and on Ester’s psychological state. The descriptionsays that Ester’s immediate reaction to the situation is to laugh, which suggests she is at leasttemporarily distracted from pain.-Vestibular sense: Ester’s vestibular sense may have been thrown off when she began to chaseafter the mystery “figure,” contributing to her inability to accurately judge her distance from thedoorway. When she smacks into the door, her vestibular sense is totally thrown off and she fallsto the ground.-Selective attention: Ester’s clumsiness might also be attributed to selective attention. She mayhave been so focused on identifying the mystery “figure” that she failed to notice other aspectsof the visual scene, like the fast approaching door.-Signal detection theory: Signal detection theory would argue that Ester’s ability to detect faintsensory signals depends on psychological factors like her motivations and expectations. Shemight not have noticed, for example, that the mystery “figure” was her roommate because shewas not expecting to see her roommate at that time; and she may have not noticed the door tothe room fast enough because she expected it to be open.-Binocular cues: Binocular cues like convergence and retinal disparity allow us to accuratelyjudge the distance of nearby objects. Perhaps Ester could not accurately judge the distance ofthe door because her binocular cues were thrown off by her erratic running.-Perceptual set: Ester’s failure to identify her roommate may have to do with her perceptual set--the way her brain constructs perceptions based on her experiences and predispositions. Forexample, she may identify her roommate based on outfits that her roommate frequently wears.\nWhen she caught a glimpse of her own favorite sweater instead, her perceptual set foridentifying self vs. others might have been confused.
