The minimum amount of stimulation a person needs to detect a stimulus 50 percent of the time is called the?
The minimum amount of stimulation a person needs to detect a stimulus 50 percent of the time is called the absolute threshold. This threshold differs for each individual based on their sensory abilities and can vary depending on factors such as noise levels and attention.
What is the difference between an absolute threshold and a decision threshold?
An absolute threshold was seen as a hypothetical barrier that incoming stimuli must overcome before they can be perceived, it was based on the ability to pass through the threshold based on absolute judgements about a single stimulus. In the case where a person were to, for example- detect a light, the strength of said light would have to be strong enough to pass the threshold for an observer to perceive it, it was generally based on the observer's ability to detect a signal.In reality however, there is no such threshold that splits the stimulus dimension into detectable and undetectable components. Rather, a stimulus must yield a sensation that exceeds the decision criterion (beta) for even the weakest signal to be perceived, so a decision threshold is the stimulus that elicits the response or perception. The detectability and reporting of the presence of a signal- or the light- are both factors because the decision threshold must be passed and the results from the strength of the stimulus, for example the light- as well the evidence of yielding such strength, must be plausible. Only in this case, do we have correct detection of a signal.
Just noticeable difference is a constant proportion of the intensity of an initial stimulus is this weber's law?
Yes, that's correct. Weber's law states that the just noticeable difference (JND) between two stimuli is proportional to the intensity of the initial stimulus. This means that the difference needed to perceive a change in stimulus intensity remains constant regardless of the initial intensity level.
The absolute threshold for hearing is arbitrarily defined?
The absolute threshold for hearing is defined as the lowest intensity of a sound that can be detected by an individual at least 50% of the time. While specific measurement criteria may vary, this threshold serves as a practical reference point for understanding auditory perception.
When several neurons are stimulated equally which one will fire first?
The neuron with the lowest threshold potential will fire first when several neurons are stimulated equally. Threshold potential is the minimum level of depolarization needed to trigger an action potential in a neuron. Neurons with lower threshold potentials are more excitable and will fire before neurons with higher threshold potentials.
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.
The term just noticeable difference is synonymous with?
difference threshold
What is the difference between an absolute threshold and a just noticeable difference?
An absolute threshold is the smallest amount of stimulation needed for a sensation to be detected, while a just noticeable difference is the smallest detectable difference between two stimuli. In other words, the absolute threshold is about detecting the presence of a stimulus, while the just noticeable difference is about discriminating between two stimuli.
What is the differences between the absolute threshold and the differential threshold Which is more important to marketers?
The absolute threshold is the minimum intensity of stimulus required to be perceived. In other words, it is the intensity amount which is needed to detect the difference between nothing and something. It is the lowest level at which an individual can experience a sensation.On the other hand, the minimal difference that can be detected between two stimuli is called the difference threshold or the j.n.d. (just noticeable difference)The main difference between the two concepts is that the differential threshold is a relative concept. Whereas the absolute threshold deals with whether or not a stimulus can be perceived, the differential threshold refers to the intensity difference needed between two stimuli before people can perceive that the stimuli are different.The marketing implication of absolute threshold is that consumers will only perceive a marketing stimulus when it is higher than absolute threshold. In other words, if images or words in a commercial are too small, consumer's sensory receptors will not ve activated and the stimulus will not be perceived. The differential threshold also has very important marketing applications Difference Threshold: The difference threshold, also known as the just noticeable difference (jnd), is the minimum difference in stimulation that a person can detect 50 percent of the time. We experience the difference threshold as a just noticeable difference. For example, let's say I asked you to put your hand out and in it I placed a pile of sand. Then, I add tiny amounts of sand to your hand and ask you to tell me when you notice any change in the overall weight. As soon as you can detect any change in the weight, that difference between the weight of the sand before I added that last bit of sand and the amount of sand after I added it, is the difference threshold.The absolute threshold is the minimum intensity of stimulus required to be perceived. In other words, it is the intensity amount which is needed to detect the difference between nothing and something.

Difference threshold of a sensation defined?
The difference threshold is the smallest amount by which two sensory stimuli can differ and still be perceived as distinct. It is also known as the just noticeable difference (JND) and varies depending on the type of sensation and the intensity of the stimuli. The difference threshold is an important concept in psychophysics for understanding how humans perceive and interpret sensory information.
What is the difference between a threshold and target?
Target is a potencial value achivable, the threshold is the status related to the percentage of achivement. E.g. Actual value: 90 Target 100 Threshold Grean is > 90 Threshold Yellow is >80 and <= 90 Threshold Red <= 80
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 difference between identification threshold and qualification threshold in impurity?
The identification threshold in impurity testing is the level at which it is possible to detect the impurity, while the qualification threshold is the level at which the impurity is deemed to be significant enough to potentially affect the quality, safety, or efficacy of the product. Identification threshold is usually lower than the qualification threshold.
What difference bvetween identification threshold and reporting threshold?
The identification threshold refers to the minimum level of a signal or data point at which a phenomenon can be reliably detected or recognized. In contrast, the reporting threshold is the level at which identified signals or data points are deemed significant enough to warrant formal reporting or action. Essentially, the identification threshold is about detection, while the reporting threshold involves determining the relevance or importance of that detection for reporting purposes.
Can rheobase be a threshold stimulus?
Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.

What is the recommended height difference between two types of flooring when installing a flooring threshold?
The recommended height difference between two types of flooring when installing a flooring threshold is typically around 1/4 inch to 1/2 inch.
