Across
  1. 2. the minimum stimulus energy needed to detect a particular stimulus 50% of the time
  2. 4. the minimum difference between two stimuli required for detection
  3. 5. diminished sensitivity as a consequence of constant stimulation
  4. 7. the study of relationships between the physical characteristics of stimuli and our psychological experience of them
  5. 10. Sensory nerve endings that respond to stimuli
  6. 12. failing to see visible objects when our attention is directed elsewhere
  7. 16. below ones absolute threshold for conscious awareness
  8. 17. processing that starts at your sensory receptors and works up to higher levels of processing
Down
  1. 1. a theory predicting how and when we will detect faint stimulus amid background stimulus
  2. 3. conversion of one form of energy to another; converting stimulus energies into neural impulses our brain can interpret
  3. 6. constructs perceptions from this sensory input by drawing on your experience and expectations
  4. 8. the focusing of conscious awareness of a particular stimulus
  5. 9. the process of organizing and interpreting sensory information, enabling us to recognize objects and events
  6. 11. failing to notice changes in the environment (a form of inattentional blindness)
  7. 13. The process when our sensory receptors and nervous system receive and represent stimulus from our environment
  8. 14. the principle that two different stimuli must differ by a constant minimum percentage
  9. 15. the activation of certain associations thus predisposing one's perception of memory or response
