Presentation Transcript

  1. SENSATION & PERCEPTION

  2. SENSATION-- • Sensation— Experience of sensory stimulation. That is, the basic experience of stimulation of the body’s senses: sight, hearing, smell, taste, balance, touch and pain.

  3. PERCEPTION • Perception— Process of creating meaningful patterns from raw sensory information.

  4. ABSOLUTE THRESHOLDS… • Absolute Thresholds—the least amount of energy that can be detected as stimulation 50 percent of the time. • Taste—1 gram of table salt in 500 liters of water • Smell—One drop of perfume diffused throughout a three-room apartment • Touch—The wing of a bee falling on your cheek from a height of 2 centimeters • Hearing—The tick of a watch from 6 meters (20 feet) away in quiet conditions • Vision— A candle flame seen from 50 kilometers (30 miles) on a clear, dark night.

  5. PERCEPTUAL CONSISTENCY… • Perceptual Constancy— The percentage of times that repeated raw sensory information is processed just as it was before. • TODAY TOMORROW

  6. UNINTENTIONAL BLINDNESS… • Unintentional Blindness—(gorilla experiment) -sometimes we do not see things if we are not looking for them
