Smallest change in sensation that a person can detect is?
The smallest change in sensation that a person can detect is known as the just noticeable difference (JND). This is the smallest difference in stimulation that a person can notice 50% of the time. The JND varies depending on the type of stimulus, with some senses being more sensitive to change than others.
The minimal difference between two stimuli that people can reliably detect?
The difference threshold, also known as the just noticeable difference, is the smallest change in a stimulus that can be detected by an observer. It is a measure of the sensitivity of a human's sensory system to changes in stimuli.
What is the difference between absolute threshold and difference threshold?
absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.
What term is used to describe the minimum amount of a stimulus that can be perceived?
The term used to describe the minimum amount of a stimulus that can be perceived is the absolute threshold. This threshold represents the lowest level of stimulation that an individual can detect.
How is information transferred when movement is fast to a stimulus?
When movement is fast in response to a stimulus, the body sends rapid signals through the nervous system. Sensory neurons detect the stimulus and quickly convey this information to the brain. The brain then processes the information and sends out signals to motor neurons, instructing the body to react accordingly.
The smallest intensity of a stimulus that you can detect 50 percent of the time is?
The smallest intensity of a stimulus that you can detect 50 percent of the time is called the absolute threshold. This threshold varies depending on the sensory system and the specific stimulus being measured.
What is the ability to detect small changes of weak stimuli and large changes in stron stimuli?
This ability is known as Weber's Law, which states that the smallest change in a stimulus that can be detected is proportional to the magnitude of the original stimulus. The law suggests that the ability to detect changes in stimuli depends on the intensity or strength of the original stimulus.
What is the Point at which a person can detect a stimulus 50 percent of time it is presented?
The point at which a person can detect a stimulus 50% of the time it is presented is known as the absolute threshold. This threshold represents the minimum intensity of a stimulus needed to detect it half of the time. It is often used in psychology to study perception and sensory processing.
What is the smallest intensity of an odor that can be detected by a human?
The nose can detect an odor from the presence of only a few molecules of substance.
How are stimulus and response related?
our senses will detect stimulus and send impulse into the integrating centre(brain) to interpret. the brain will produce appropriate response toward the stimulus to the effector. e.g when Telephone ring, the ears will detect the stimulus(sound) and the brain will produce the response to pick up the phone (copy from Yahoo answers)

What is guesses law?
Guess's Law, often associated with the field of psychophysics, suggests that the perception of stimuli is influenced by factors such as the intensity of the stimulus and the observer's sensitivity. It implies that the ability to detect changes in stimulus intensity follows a logarithmic scale, meaning that larger changes are necessary to notice differences at higher intensity levels. This principle is foundational in understanding human sensory perception and the thresholds of awareness.
What is the function of the cold receptor?
to detect stimulus
Which type of stimulus do mechanoreceptors detect?
Sound
What does limen mean in psychology?
In psychology, "limen" refers to the threshold or point at which a stimulus becomes perceptible to an individual. It is often used in the context of sensory perception, where the limen determines the minimum intensity of a stimulus required for it to be noticed, known as the "absolute threshold." Additionally, it can refer to the difference threshold, which is the minimum change in stimulus intensity needed for a person to detect a difference. Overall, limen is crucial for understanding how we perceive and respond to various stimuli in our environment.
What is value of 1 decibal?
One decibel (dB) is a logarithmic unit used to express the ratio between two values, commonly used in acoustics, electronics, and telecommunications. It represents a change in intensity or power level, with a difference of 10 dB corresponding to a tenfold increase in power. In terms of sound intensity, an increase of 1 dB is generally considered the smallest change in sound level that the average human ear can detect.
What is stimulus with examples?
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
