Questions and Answers

What is the correct sequence of the stages in the stimulus-sensation-perception-emotion-memory process?

  • stimulus-sensation-perception-emotion-memory (correct)
  • perception-sensation-emotion-memory-stimulus
  • emotion-sensation-perception-memory-stimulus
  • sensation-perception-emotion-memory-stimulus
  • What is the role of sensation in the stimulus-sensation-perception-emotion-memory process?

  • Sensation extracts a mental representation from the physical stimulus.
  • Sensation creates emotions in response to the physical stimulus.
  • Sensation activates sensory brain pathways in response to a physical stimulus. (correct)
  • Sensation stores the memory of the physical stimulus.
  • What is the difference between sensation and perception?

  • Sensation is the creation of emotions in response to a physical stimulus, while perception is the storage of memories.
  • Sensation is the extraction of a mental representation from a physical stimulus, while perception is the activation of sensory brain pathways.
  • Sensation and perception are the same process, just with different names.
  • Sensation is the activation of sensory brain pathways, while perception is the extraction of a mental representation from sensation. (correct)
