  2. Chapter 4SENSATION AND PERCEPTION Section 1:Sensation and Perception: The Basics Section 2: Vision Section 3: Hearing Section 4: Other Senses Section 5: Perception

  3. Chapter 4 Chapter 4: Section 1 Sensation and Perception: The Basics

  4. Chapter 4 Main Objective: • Distinguish between sensation and perception, and explain how they contribute to an understanding of our environment.

  5. Chapter 4 CHAPTER 4 Sensation and Perception Senses Vision Hearing Smell Touch Taste Body Senses

  6. Chapter 4 What is Sensation and Perception?????? • Sensation: • The stimulation of sensory receptorsand the transmission of sensory informationto the central nervous system (the spinal cord and brain). • Perception: • Psychological process through which we interpret sensory stimulation. • EX: We realize that the people on a small TV are bigger in real life.

  7. Chapter 4 Stimulation of senses and the ways in which people interpret that stimulation are affected by several concepts: • Absolute threshold • Difference Threshold • Signal-detection theory • Sensory adaptation

  8. Chapter 4 Absolute Threshold: • Absolute Threshold: • The weakest amount of a stimulus that can be sensed. • EX: Hearing the first beep in a hearing test. • Dogs can hear and smell things that people cannot…they have a different threshold. • Thresholds differ from person to person!

  9. Chapter 4 Difference Threshold: • Difference threshold: • The minimum amount of difference that can be detected between two stimuli. • EX: differences in shades of color.

  10. Chapter 4 Signal-Detection Theory: • A method of distinguishing sensory stimuli that takes into account not only their strengths but also such elements as the setting, your physical state, your mood, your attitudes, and motivation. • EX: Mind wandering in class… you still hear but your mind will wander.

  11. Chapter 4 Sensory Adaptation: • The process by which we become more sensitive to weak stimuli and less sensitive to unchanging stimuli. • Sensory systems adapt to changing environment. • Seeing people in movie theater (weak stimuli) • City dwellers adapt to sounds of traffic (unchanging stimuli)
