Study Notes
Chapter 4: Sensation and Perception
- This chapter covers sensation and perception
- Various topics are discussed in this chapter, divided into sections relating to different senses
4.1 Concepts of Sensation and Perception
- Discusses the concepts of sensation and perception
- Details the stages of sensation and perception
4.2 The Senses: The Visual Sense (Sight)
- Covers the visual sense (sight)
- Explains the stages of the sense of sight. This includes the physical stimulus (electromagnetic energy), physiological receptors like the cornea, pupil, iris, lens, retina, and macula, and the psychological response relating to the organization and perception of colors.
- Includes common visual defects such as hyperopia, presbyopia, myopia, astigmatism, color blindness (totally, partially, trichromat), strabismus (cross-eyedness), and scotoma.
4.3 The Senses: The Auditory Sense (Hearing)
- Covers the auditory sense (hearing)
- Identifies parts of the human ear including functions
- Explains the transduction process
- Describes individual responses to auditory stimuli
- Outlines common hearing defects (conduction, nerve deafness)
4.4 The Senses: The Olfactory Sense (Smell)
- Covers the olfactory sense (smell)
- Identifies parts of the nose and discusses its functions
- Explains the various stages involved in the sense of smell
- Describes physical stimuli (volatile substances and fat-soluble substances) and physiological mechanisms (olfactory bulbs and the olfactory tract)
- Details psychological responses (primary odors) and Amoore's seven primary smells
4.5 The Senses: The Gustatory Sense (Taste)
- Covers the gustatory sense (taste)
- Details the parts of the tongue and their functions
- Explains taste buds and their roles, the papillae
- Discusses the stages of the sense of taste, including the psychological response, encompassing 5 basic taste qualities (salty, sweet, bitter, sour, umami)
4.6 The Senses: The Tactile Sense (Touch)
- Covers the tactile sense (touch)
- Identifies and describes the different parts of the skin and their individual functions
- Explains the stages involved in the sense of touch
- Outlines physical stimuli (pressure, pain, and temperature changes)
- Describes physiological receptors (free nerve endings, Meissner/Merkel corpuscles, hair bulbs/basket nerve endings, Ruffini cylinders, Krause end bulbs, Pacinian corpuscles)
- Describes psychological responses (qualitative differences in touch, responses to pain, warmth, and cold, and adaptation differences)
4.7 The Senses: The Kinesthetic Sense (Body Movement)
- Covers the kinesthetic (body movement) sense
- Discusses the sense of body movement and its importance
- Analyzes and explains the process of this sense
- Describes physical stimuli (movement in joints, stretch and tension in muscles) and physiological receptors (free nerve endings, Golgi tendon organs, linings of joints)
- Details the psychological response, explaining how it influences motor activities and gives continuous information during movement
4.8 The Senses: The Equilibrial Sense (Body Balance)
- Covers the equilibral (body balance) sense
- Illustrates how body balance works through different stages
- Explains applications of this sense
- Discusses physical stimuli, relating them to the speed of rotation of head & changes in speed/gravity, and their effect on inner eardrum and semi-circular canals
- Explains the role of the vestibular portion of the inner ear, and the physiological mechanisms (semi-circular canals & endolymph)
- Details the psychological responses—emphasizing the body's position in relation to gravity, the body's motion, and bodily balance in space
4.9 Extra Sensory Perception
- Covers extra sensory perception (ESP)
- Discusses what ESP is
- Includes recall/share of personal ESP experiences
- Provides reasons why psychologists remain skeptical about ESP, touching on issues of replication failure, possible fraud, and methodological limitations
