Biological Psychology: Sensation and Perception

What is the difference between sensation and perception? Fill in the blank: Sensation is ________ from physical stimulation, while perception is ________ and making sense of that sensation.

• Sensation is feeling from physical stimulation, while perception is organizing and making sense of that sensation.

• Sensation is organizing from physical stimulation, while perception is feeling and making sense of that sensation.

• Sensation is imagining from physical stimulation, while perception is ignoring and making sense of that sensation.

• Sensation is remembering from physical stimulation, while perception is forgetting and making sense of that sensation.

Which of the following best describes 'Reception' in the sensation process?

• Converts physical signals into electrical messages for the brain

• Receptors detect stimuli (e.g., sunlight, sound)

• Electrical messages travel to the brain for processing

• Organizing and making sense of sensation

Fill in the blank: Sensory Transduction is the process that ________.

• converts physical signals into electrical messages for the brain

• stores memories in the hippocampus

• regulates hormone levels in the bloodstream

• controls voluntary muscle movements

Which step in the sensation process involves electrical messages traveling to the brain for processing and interpretation?

• Reception

• Sensory Transduction

• Pathways

• Perception

Fill in the blank: The brain filters out ________ stimuli, focusing on what matters.

• unimportant

• important

• visual

• auditory

Which of the following is NOT a factor influencing perception?

• B) Past experiences

• C) Expectations

• D) Sensory Transduction

What is the Absolute Threshold?

• Minimum stimulus detectable at least half the time.

• Maximum stimulus detectable at all times.

• Minimum response to any stimulus.

• Average stimulus detected by most people.

What is the Differential Threshold (Just Noticeable Difference)?

• Smallest detectable difference between stimuli.

• The maximum intensity of a stimulus.

• The average value of two stimuli.

• The total absence of any stimulus.

What is the Terminal Threshold?

• Upper limit of sensory perception.

• Lowest level of stimulus that can be detected.

• Point at which a stimulus becomes painful.

• Threshold for adaptation to a stimulus.

What does psychophysics study?

• The relationship between physical stimuli and perception.

• The structure of the nervous system.

• The process of memory formation.

• The development of language skills.
