Understanding Brain Function and Perception

What does the myth of being "right-brained" or "left-brained" suggest?

• People use only one side of their brain for all tasks.

• People are either creative and intuitive or logical and analytical.

• Both sides of the brain work independently without communication.

• The brain is not involved in creative tasks.

Which part of the brain is responsible for communication between the two hemispheres?

• Cerebellum

• Corpus callosum

• Medulla oblongata

• Thalamus

What is the role of the right hemisphere in solving math problems?

• It is not involved at all.

• It provides creativity and intuition.

• It handles all logical calculations.

• It only processes visual information.

What does the term "functional specialization" refer to in brain function?

• Each hemisphere performs identical tasks.

• Some functions are more dominant in one hemisphere.

• Both hemispheres perform all tasks equally.

• The brain does not specialize in any function.

What is the absolute threshold?

• The maximum level of stimulus intensity detectable.

• The minimum level of stimulus intensity needed to detect a stimulus half the time.

• The level of stimulus intensity that cannot be detected.

• The average level of stimulus intensity detectable.

What does Signal Detection Theory (SDT) consider in detecting signals?

• Only sensory input

• Only decision-making processes

• Both sensory input and decision-making processes

• Neither sensory input nor decision-making processes

What is Weber’s law?

• Stimuli must differ by a constant amount to be perceived as different.

• Stimuli must differ by a constant minimum percentage to be perceived as different.

• Stimuli must be identical to be perceived as different.

• Stimuli must differ by a variable percentage to be perceived as different.

What is an example of sensory adaptation?

• Hearing a loud noise for the first time

• Feeling a rock in your shoe less over time

• Seeing a bright light continuously

• Tasting a new flavor

What is perceptual set?

• The ability to perceive stimuli without any expectations

• What we expect to see, influencing what we do see

• The inability to perceive stimuli

• The random perception of stimuli

Which processing method uses experiences to make quick judgments?

• Bottom-up processing

• Top-down processing

• Lateral processing

• Parallel processing
