You asked: What are feature detectors AP 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 quizlet?

Feature detectors. Are neurons in the brain that respond to specific aspects of a stimulus. -Edges. –Lines. —Angles.

Where are feature detectors located and what is their function?

Feature detectors are neurons in the retina or brain that respond to specific attributes of a stimulus, movement, orientation etc.

Where are feature detectors located and what is their function How do feature detectors work together to portray a whole image?

Where are the feature detectors located, and what is their function? How do feature detectors portray a “whole” image? specialized neurons in the occipital lobe’s visual cortex that receive information from individual ganglion cells in the retina; piece together lines, edges, angles, etc.

Are rods and cones feature detectors?

The retina has two types of photoreceptor cells: rods, which detect brightness and respond to black and white, and cones, which respond to red, green, and blue. Colour blindness occurs when people lack function in the red- or green-sensitive cones.

What is an example of feature detectors?

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.

How do feature detectors work?

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.

What is top down in psychology?

In top-down processing, perceptions begin with the most general and move toward the more specific. These perceptions are heavily influenced by our expectations and prior knowledge. 1 Put simply, your brain applies what it knows to fill in the blanks and anticipate what’s next.

Where are feature detectors located in the brain?

Perception is created in part through the simultaneous action of thousands of feature detector neurons—specialized neurons, located in the visual cortex, that respond to the strength, angles, shapes, edges, and movements of a visual stimulus (Kelsey, 1997; Livingstone & Hubel, 1988).

What do feature detectors help you to perceive?

Feature detectors are also thought to play an important role in speech perception, where their function would be to detect those binary features that distinguish one phoneme from another. … Also called feature analyzer.

What are the four basic sensations skin can detect?

The thousands of nerve endings in the skin respond to four basic sensations: Pressure, hot, cold, and pain, but only the sensation of pressure has its own specialized receptors. Other sensations are created by a combination of the other four.

What are three types of sensations that your skin can detect?

The skin contains sensory receptors for touch, pressure, pain, and temperature (warmth and cold). Three types of receptors detect touch: Meissner corpuscles, Merkel disks, and free nerve endings.

How do we see psychology?

Rods and cones are connected (via several interneurons) to retinal ganglion cells. Axons from the retinal ganglion cells converge and exit through the back of the eye to form the optic nerve. The optic nerve carries visual information from the retina to the brain.

What are the stages of color vision?

The first stage can be considered as the receptor stage which consists of the three photopigments (blue, green and red cones). The second is the neural processing stage where the colour opponency occurs. The second stage is at a post-receptoral level, and occurs as early as the horizontal cell level.

What is dark adaptation in psychology?

the ability of the eye to adjust to conditions of low illumination by means of an increased sensitivity to light.

Are feature detectors located in the occipital lobe?

Word(s) of the Day (1) Feature detectors– specialized neurons that respond only to certain sensory information. David Hubel and Torsten Wiesel demonstrated that specialized neurons in the occipital lobe’s visual cortex respond to specific features of an image such as angles, lines, curves, & movement.
