Sensation color and absolute threshold correct

Perception is the mental process of sorting, identifying, and arranging the raw data of experience into meaningful patterns. Sensation is the activation of the receptors.

Sensation is the activation of the receptors by stimuli. Ganglion cells are connector neurons that come into play later in the process. They take information from receptors and related cells and then send it on for more processing.

Receptors respond directly to stimuli. Cells that are triggered by light, vibrations, sounds, touch, or chemical substances are called sensory receptors; examples are rods, cones, and hair cells. The point at which a person can detect a stimulus 50 percent of the time it is presented is called the absolute threshold.

The difference threshold is the smallest difference between two stimuli that a person can detect 50 percent of the time it is presented. Response threshold is not a term used in the text. The term just noticeable difference is the correct synonym. The term just noticeable difference is synonymous with difference threshold and refers to the detection of change.

The absolute threshold is the lowest intensity of a particular stimulus that enables the average person to consciously detect that stimulus 50 percent of the time it is presented.

There is no such term as psychophysical threshold. The smallest amount of a particular stimulus required to produce any sensation at all in a person is the absolute threshold.

Below that level the stimulus cannot be detected reliably. The smallest amount of a stimulus required to produce any sensation at all in a person is the absolute threshold.

The term minimum would seem to be correct, but it is not used. The difference threshold is defined as the degree of change in a stimulus level that is required in order for a person to detect it 50 percent of the time.

The lowest stimulus intensity required for detection is the absolute threshold, and the smallest noticeable difference between a standard stimulus intensity and another stimulus value is the difference threshold. The lowest stimulus intensity required for detection is the absolute threshold, whereas the smallest noticeable difference between a standard stimulus intensity and another stimulus value is the difference threshold.

The opponent-process principle refers to a concept regarding color vision. When Ann went to her doctor, he gave her a hearing test.

Sensation color and absolute threshold correct

During the test, the doctor presented tones to Ann through earphones. The tones started at a low intensity and then became louder. The doctor asked Ann to raise her hand whenever she started to hear a sound.

Subliminal stimuli are believed to operate at an unconscious level, meaning that people would be unaware of having perceived them. Below threshold perceptions would refer to stimuli that are too weak to be perceived, not necessarily to those that are perceived on an unconscious level.

Laverne goes to a movie theater to watch her favorite movie. About halfway through the movie she becomes aware of an overpowering hunger for popcorn.

Selective perception would refer to a choice between above threshold stimuli. She is responding to subliminal perception, which is not consciously detected.

Sensation and Perception

Weber did not focus on the absolute threshold but is known instead for his work on the just noticeable difference jnd.

Weber provided a formulation that is used to predict the smallest detectable difference between two stimuli. The average threshold for human vision is a candle flame seen from 30 miles.

We can see a candle flame at 30 miles on a clear, dark night, and we can hear the tick of a watch 20 feet away in a quiet room. Difference threshold has to do with the detection of changes, not the lowest detectable stimulus level. These are absolute thresholds, as they are at the lower limits of our detection.

The average threshold for human hearing is the tick of a watch from 20 feet under very quiet conditions. When you first put your hat on, you can feel it quite easily, but after a while, you forget that you are wearing a hat at all—the sensation is gone.

Sensory fatigue is not the proper term, though it sounds like it could be correct.

Sensation and Perception Sensory Thresholds and Psychophysics Sensation occurs when sensory areas in the cerebral cortex receive nerve impulses, usually when body sensors such as the touch receptors of the skin are stimulated.

Sensation must be distinguished from perception, which is based on the interpretation of patterns of sensation.
