Sensation and Perception

Heidi and Marissa are discussing their experiences at a concert. Heidi mentions the loud music and bright lights, while Marissa talks about how the music made her feel. What is the difference between sensation and perception in this context?

• Sensation is the physical process of detecting stimuli, like the loud music and bright lights, while perception is the psychological process of interpreting sensory information, like how the music made Marissa feel.

• Sensation and perception are the same thing.

• Sensation is the process of interpreting sensory information, like how the music made Marissa feel, while perception is the physical process of detecting stimuli, like the loud music and bright lights.

• Sensation and perception are unrelated processes.

Christina and Jonathan are conducting a study on human perception. They want to determine the absolute threshold for a specific stimulus. What does the absolute threshold represent in this context?

• The minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time by the participants.

• The maximum amount of stimulus energy that can be detected by the sensory receptors of the participants.

• The threshold for conscious awareness of a stimulus by the participants.

• The threshold for subliminal messages to be detected by the participants.

During a hearing test, Briana and Dylan are trying to determine the smallest change in volume that they can detect. What is this difference threshold also known as?

• Just noticeable difference (jnd)

• Absolute threshold

• Subliminal threshold

• Sensory adaptation threshold

During a biology class, Nigel learns about transduction. What does transduction refer to in the context of sensory perception?

• The conversion of sensory stimulus energy to action potential.

• The process of sensory adaptation.

• The process of perceiving stimuli.

• The process of detecting absolute thresholds.

Adriel and Seth are in a room with a constant humming sound from an air conditioner. What is the phenomenon that allows them to eventually stop noticing the sound?

• The phenomenon of perceiving stimuli that remain relatively constant over prolonged periods of time.

• The process of converting sensory stimulus energy to action potential.

• The process of detecting the difference threshold.

• The phenomenon of no longer perceiving stimuli that remain relatively constant over prolonged periods of time.

During a lecture, Jasmyn and Trevor are trying to understand the role of attention in perception. Which statement best describes the role of attention in perception?

• Attention determines what is sensed and what is perceived.

• Attention has no effect on perception.

• Attention only affects sensation, not perception.

• Attention is only relevant for subliminal messages.

Rocco and Dylan were playing a video game while Adelaide, Christina, and Erin were having a conversation. Despite the conversation happening in the same room, Rocco and Dylan didn't notice it. What is this scenario an example of?

• The failure to notice something that is completely visible because attention is focused on something else, also known as inattentional blindness.

• The inability to detect absolute thresholds.

• The inability to detect subliminal messages.

• The failure to perceive stimuli that remain relatively constant over prolonged periods of time.

During a noisy school assembly, Nigel is trying to listen to his friend Kyle's story. Which theory best explains Nigel's ability to focus on Kyle's voice despite the surrounding noise?

• The ability to identify a stimulus when it is embedded in a distracting background.

• The theory that explains the difference threshold.

• The theory that explains sensory adaptation.

• The ability to detect subliminal messages.

Dani and Seth are having a debate. Dani believes that their personal beliefs, values, and life experiences can affect how they perceive things around them. Seth disagrees. How can Dani explain her point to Seth?

• Dani can say that beliefs, values, and life experiences can influence how sensory information is organized, interpreted, and consciously experienced.

• Dani can say that beliefs, values, and life experiences have no effect on perception.

• Dani can say that beliefs, values, and life experiences only affect sensation, not perception.

• Dani can say that beliefs, values, and life experiences only affect subliminal messages.

Adriel and Kyle are arguing about a drawing they saw in a psychology book. The drawing is known as the Müller-Lyer illusion. Can you describe what this illusion is?

• An illusion where lines in the drawing appear to be different lengths, but Adriel insists they are actually the same length.

• An illusion where lines in the drawing appear to be different colors, but Kyle believes they are actually the same color.

• An illusion where lines in the drawing appear to be moving, but Isabel, who was also there, says they are actually stationary.

• An illusion where lines in the drawing appear to be curved, but Jasmyn and Isabella, who were also looking at the book, argue they are actually straight.
