AP® Psychology Sensations and Perception | Unit IV Flashcards
Unit | IV
The process by which our sensory receptors receive and represent stimulus energies from our environment.
Sensation
Unit | IV
The process of organizing and interpreting sensory information.
Perception
Unit | IV
Sensory nerve endings that respond to stimuli
Sensory receptors
Unit | IV
Constructs sensory perception from these sensory inputs by drawing on your experience and expectations.
Top-down processing
Unit | IV
Starts at your sensory receptors and works up to higher levels of processing.
Bottom-up processing
Unit | IV
The focusing of concious awareness on a single stimuli.
Selective attention
Unit | IV
The transforming of stimulus energies, such as sight, smell, and touch into neural impulses that our brain can interpret.
Transduction
Unit | IV
The failure to see visible objects when attention is directed elsewhere.
Inattentional blindness
Unit | IV
The failure to notice changes in the environment.
A type of inattentional blindness
Change blindness
Unit | IV
The minimun energy needed to detect stimulus 50 percent of the time.
May be different based on accesories such as glasses, or hearing aids.
Absolute Threshold
Unit | IV
A theory predicting how and when we detect the presence of a faint stimulus (signal) amid backgroud stimulation (noise). Assumes there is no single absolute threshold and that detection depends partly on a person’s experience, expectations, motivation, and alertness.
Signal Detection Theory
Unit | IV
Below one’s absolute threshold for conscious awareness.
Subliminal
Unit | IV
The activation, often unconsciously, of certain associations, thus predisposing one’s perception, memory, or response.
Priming
Unit | IV
The minimun difference between two different stimuli required for detection 50 percent of the time.
We experience this as a just noticable difference. ( or jnd)
Difference Threshold
Unit | IV
Diminished sensitivity as a consequence of constant stimulation.
