Sensory Systems Quiz

What is the difference between bottom-up processing and top-down processing?

• Bottom-up processing is guided by higher-level mental processes, while top-down processing is not.

• Bottom-up processing starts with sensory input, while top-down processing starts with a cognitive process.

• Bottom-up processing refers to how our eyes process light, while top-down processing refers to how we process sounds.

• Bottom-up processing is the same as top-down processing; there is no difference.

What is the difference between absolute thresholds and difference thresholds?

• Absolute thresholds refer to the minimum stimulus energy needed for detection, while difference thresholds refer to the minimum difference in stimulus energy we can detect.

• Absolute thresholds are the maximum levels of stimulus energy we can detect, while difference thresholds are the minimum levels.

• Absolute thresholds refer to the difference in stimuli required to detect a change in intensity, while difference thresholds refer to the initial detection of stimuli.

• There is no difference; absolute thresholds and difference thresholds are the same thing.

How are we affected by subliminal stimuli?

• Subliminal stimuli can always influence our behavior significantly.

• Subliminal stimuli affect us only when we are fully aware of them.

• Subliminal stimuli are below our absolute threshold for conscious awareness.

• Subliminal stimuli are above our absolute threshold and always result in conscious perception.

What is the function of sensory adaptation?

• To increase sensitivity to stimuli that are constantly changing

• To decrease sensitivity to unchanging stimulus information

• To prevent any sensory information from reaching the brain

• To maintain the same level of sensitivity to all stimuli at all times

What is sensation?

• The process by which we organize and interpret sensory information.

• The process by which our sensory receptors and nervous system receive stimulus energies from our environment.

• The ability to recognize meaningful objects and events.

• The interpretation of sensory information to understand its meaning.

What is perception?

• The process by which our sensory receptors and nervous system receive stimulus energies from our environment.

• The ability to recognize meaningful objects and events without sensory information.

• The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.

• The initial contact between our sensory receptors and the environment.

What term refers to the brain making sense of sensory information?

• Cognition

• Perception

• Sensation

• Reflection

What does bottom-up processing start with?

• Experience and expectations

• Sensory input

• Logical reasoning

• Memory recall

What is an example of bottom-up processing given in the image?

• Seeing a windy stick and thinking it's a snake

• Recognizing a creature as a snake based on its slithering movement

• Expecting to see snakes and therefore seeing them everywhere

• Using memory to identify objects

What does top-down processing rely on?

• Sensory input

• Experience and higher-level processes

• Immediate surroundings

• Random guesses
