Ears 2 Flashcards
- near center of retina
- fine detail and color vision
- daylight or well-lit conditions
Cones
Central point in the retina, around which the eye’s cones cluster
Fovea
- peripheral retina
- detect black, white, and gray
- twilight or low light
Rods
Minimum stimulation needed to detect a particular stimulus 50% of the time
Absolute Threshold
Minimum difference between two stimuli required for detection 50% ott
Difference threshold
Predicts how & when we detect the pressure of a faint stimulus amid background stimulation (noise)
Signal Detection Theory
When stimuli are below ones absolute threshold for conscious awareness
Subliminal Perception
To perceive as different two stimuli must differ by a constant minimum percentage
Weber’s Law
Diminished sensitivity as a
consequence of constant stimulus
Sensory adaption
Process by which sensory receptors & nervous system receive and represent stimulus energy
Sensation
