What are feature detectors in psychology?
any of various hypothetical or actual mechanisms within the human information-processing system that respond selectively to specific distinguishing features.
How do feature detectors work psychology?
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 are feature detectors in psychology quizlet?
What are feature detectors? Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.
What psychologist discovered feature detectors?
David Hubel
Feature detection was discovered by David Hubel and Torsten Wiesel of Harvard University, an accomplishment which won them the 1981 Nobel Prize.
What is feature detector approach?
Feature detection is a process by which the nervous system sorts or filters complex natural stimuli in order to extract behaviorally relevant cues that have a high probability of being associated with important objects or organisms in their environment, as opposed to irrelevant background or noise.
Are feature detectors in the retina?
Feature detectors are neurons in the retina or brain that respond to specific attributes of a stimulus, movement, orientation etc.
What are the different types of feature detectors?
The three major groups of so-called feature detectors in visual cortex include simple cells, complex cells, and hypercomplex cells. Simple cells are the most specific, responding to lines of particular width, orientation, angle, and position within visual field.
What is the process of feature detection?
Where are feature detectors?
What is the definition of feature detector in psychology?
Feature Detectors are specialized nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.
Where are feature detectors located in the brain?
Beyond pyramidal cells and spherical cells, a more complex feature detector exists in the dorsal torus semicurcularis of the midbrain because the separate streams of amplitude and phase information converge on higher order sign-selective neurons in this region of the midbrain.
What is an example of a feature detector?
In a simple example, prey animals like horses and sheep need to be able to quickly identify movement, even when it occurs in their peripheral vision. Their feature detection is fine-tuned for any signs of movement so they can identify predators and respond to them.
What is the definition of feature detectors?
Feature detectors are individual neurons-or groups of neurons-in the brain which code for perceptually significant stimuli. Early in the sensory pathway feature detectors tend to have simple properties; later they become more and more complex as the features to which they respond become more and more specific.
