Psychology 1 – Introduction to Psychology Winter Quarter, 2008 Reading Guide for Chapters 4 and 5 pp. 98-149, 362-395 Week 3 This sheet is fairly comprehensive, but you should always refer back to the official fair game sheet posted online. 1. Chapter 4 – Sensation and Perception a. Vision i. Retina – a layer of visual receptors covering the back surface of the eyeball 1. Cones – visual receptors that are adapted for color vision, daytime vision, and detailed vision. 2. rods – visual receptors that are adapted for vision in dim light ii. Lens – a flexible structure that can vary in thickness 1. Accommodate – to adjust its focus for objects at different distances. iii. Fovea – the central area of the human retina iv. Blind spot – area where the optic nerve exits the retina v. Tri-chromatic theory 1. in your own words – theory that color vision depends on the relative rate of response of three types of cones 2. example – our receptors respond to three primary colors vi. Opponent process theory 1. in your own words – we perceive color not independent colors but in terms of a system of paired opposites- red versus green, yellow versus vii. Retinex theory 1. in your own words – (retina & cortex)--- we perceive color through the cerebral cortex’s comparison of various retinal patterns viii. Color blindness – being unable to distinguish certain colors b. Hearing i. Frequency/pitch – the frequency of sound is the number of cycles( vibrations) that it goes through per second, pitch is a perception closely related to frequency. ii. Loudness/amplitude – is a perception that depends on the amplitude of sound waves (intensity) iii. Conduction deafness – results when the bones connected to the eardrum fail to transmit sound waves properly to the cochlea. iv. Nerve deafness – results from damage to the cochlea, the hair cells, or the auditory nerve v. Frequency principle 1. in your own words –a sound wave though the fluid of the cochlea vibrates all the hair cells, which produce action potentials in synchrony with the sound waves. vi. Volley principle 1. in your own words – respond to each vibration by producing an action potential vii. Place principle 1. in your own words – the highest frequency sounds vibrate hair cells near the stirrup end and lower frequency sounds vibrate hair cells at points farther along the membrane viii. Sound localization 1. in your own words – how you interpret where a sound is coming from
