What is feature detection AP Psychology?
Feature Detectors – nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.
What is amplitude psychology Chapter 5?
amplitude. the intensity or amount of energy of a wave, reflected in the height of the wave; the amplitude of a sound wave determines a sound’s loudness.
What is signal detection quizlet?
signal detection theory. a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Assumes there is no single absolute threshold and that detection depends partly on a person’s experience, expectations, motivation, and alertness.
What is bipolar cells AP Psych?
bipolar cells. specialized cells which connect rods and cones to the ganglion cells of the optic nerve. blind spot. the point at which the optic nerve leaves the eye ” creating a “”blind”” spot because no receptor cells are located there. ( Myers Psychology 8e p.
What do feature detectors detect?
The ability to detect certain types of stimuli, like movements, shape, and angles, requires specialized cells in the brain called feature detectors. Without these, it would be difficult, if not impossible, to detect a round object, like a baseball, hurdling toward you at 90 miles per hour.
What is feature detection in image processing?
Feature detection is a method to compute abstractions of image information and making local decisions at every image point whether there is an image feature of a given type at that point or not. Feature detection is a low-level image processing operation.
What is timbre AP Psychology?
Timbre. the quality or texture of sound; caused by overtones. Pitch. auditory experience corresponding to the frequency of sound vibrations, resulting in a higher or lower tone; humans respond to 20 Hz to 20,000 Hz.
What is frequency in AP Psychology?
Frequency theory: The rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone; enabling us to sense its pitch. Place theory: links the pitch we hear with the place where the cochlea’s membrane is stimulated.
What is signal detection theory in psychology example?
The word “signal” changes meaning depending on the situation or the example. For instance, if someone gets injured, the doctor’s analysis can be measured using signal detection theory. An example of a “hit” would be if the person pulls a muscle, and the doctor correctly diagnoses the injured person (response-yes).
What does signal detection theory mean in psychology?
Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the …

What is Hue AP Psych?
hue. color, or aspects of colors; most people can name 150. ganglion cells. neurons that connect the bipolar cells to the optic nerve; an interneuron; one million in each eye; summarizes and organizes data from rods/cones and sends it to the brain.
