Sensation
Starting with the sensory input, the brain attempts to
understand/make sense.
bottom- up processing
Level of conscious awareness we are only one place at a time.
Selective inattention
Minimum stimulation needed to detect a particular stimulus
Absolute Threshold
Commercials that promote a message indirectly
Subliminal Stimuli
To perceive a difference between two stimuli, they must differ by a constant proportion.
Weber's Law
Tendency to focus on just a particular stimulus
Selective attention
A hearing specialist exposes both of your ears to varying sound levels.
Audition
Focus on one stimulus at a time (often at the expense of others)
Selective Attention
Process by which our sensory receptors and nervous system recieve stimulus from our environment.
What is sensation?
A phenomenon where exposure to a stimulus influences a person's response to a subsequent stimulus
Priming?
study of the relationship between the physical characteristics of stimuli
Psychophysics
Predicting how and when we detect the presence of a faint stimulus.
Signal Detection Theory
Mental predisposition to perceive one thing and not another.
Perceptual Set
A process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
Perception
Diminished sensitivity to stimuli as a consequence of constant stimulation
Sensory adaptation
Each of your senses receives information from the environment, converts it into neural signals in a process called
Transduction
The two signals of Signal detection theory are?
1. Strength of the signal
2. Psychological state
