PSY CHP.5 Flashcards
The detection of signals in the environment by sensory receptors in the body
Sensation
The organization and interpretation of sensory information
Perception
Which theory studies the extent to which we notice things based on a sensory process and a decision process?
Signal detection theory
J.N.D measures how much change is necessary for us to notice change has taken place
Just noticeable difference
minimum amount of stimulation needed to detect a sensory input
Absolute threshold
Attention focuses on process such as sensory blank and blank attention
Sensory adaptation, Selective attention
Explain the the direction of processing
And also what kind of processing is this?
1. Stimulus blank
2. Blank receptors
3. Blank impulses
4. B_______
Blank up processing
- Stimulus energy
- Sensory receptors
- Neutral impulses
- Brain
Bottom up processing
Blank processing can drive how we process perceptual information
Top down
Blank may occur due to a breakdown in the bottom up and top down process
Synaesthesia
Blank come by virtue of having two eyes
Binocular cues
Blank is the term for the difference between the images that reach each eye
Retinal disparity
Blank can be perceived with only one eye and reflect information in the environment
Monocular cues
There are two types of information we use to perceive depth
Binocular Cues
Monocular Cues
The Blank psychologist described various different principles of perceptual organization
Gestalt
Similarity
Continuity
Proximity
Closure
Blank come by the virtue of having two eye
Binocular cues
Blank is the term for the difference between the images that reach each eye
Retinal disparity
Blank refers to the fact that a sound coming from the right side of your body is more intense at your right ear than at your left ear because of the attenuation of the sound wave as it passes through your head
Interaural level difference
The conversion from sensory stimulus energy to action potential is known as blank
transduction
It is also possible for us to get message that are presented below the threshold for conscious awareness these are called blank
subliminal message
the blank has a higher concentration of receptors
fovea
the blank theory of pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies.
place
specialized photoreceptor that works well in low light conditions
rod
visible part of the ear that protrudes from the head
pinna
specialized photoreceptor that works best in bright light condition and detects color
cone
