Nativist-perception that claims that information in the sensory world s complex and abundant, and therefore the perceptual systems need only directly perceive such complexity-Gibsonian
Why might Fechner's law be seen as an improvement over Weber's Law?
Fechner's law states our sensory experience changes at a lower rate than does the physical intensity
What are psychophysics?
The study of the relation between physical stimuli and perception events
What is absolute threshold?
The smallest amount of a stimulus necessary to allow an observer to detect its presence
What is difference threshold?
(JND) the smallest difference between two stimuli that can be detected
A just noticeable difference between two stimuli stimuli is related to the magnitude or strength of the stimuli
Stevens power law
a mathematical formula that describes the relationship between stimulus intensity and our perception; it allows for both response compression and expansion
Signal detection theory
The theory that in every sensory detection or discrimination, there is both sensory sensitivity to the stimulus and a criterion used to make a cognitive decision
when the observer mistakes a harmless or null signal for a dangerous or an active signal
A harmful signal is perceived as harmless
When a harmless signal is perceived as harmless
When a harmful signal is correctly perceived as harmful
An internal cutoff, determined by the observer makes one response and below which the observer makes another response
Sensorineural hearing loss
Permanent hearing loss caused by damage to the cochlea or auditory nerve
