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.

The absolute threshold refers to the minimum level of stimulation needed for a sensory system to detect a stimulus. The decision threshold is the point at which a person decides whether a stimulus is present or absent based on the strength of the stimulus compared to a set criterion.

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.
When a neuron reaches its threshold?
When a neuron reaches its threshold, it initiates an action potential. This is a brief electrical impulse that allows for communication between neurons. The action potential travels down the axon of the neuron to transmit signals to other neurons or cells.
What is the difference between absolute continuity and differential in psychology?
In psychology, absolute continuity refers to the smooth and uninterrupted progression of thoughts or behaviors, while differential involves understanding and identifying differences or variations between individuals or groups in terms of psychological traits or behaviors. Absolute continuity focuses on the flow and consistency of mental processes, while differential examines the unique characteristics that distinguish one person from another.
What is the difference between understanding and obedience?
Understanding involves comprehending the reasons behind a rule or instruction, whereas obedience is following the rule or instruction regardless of one's understanding. Understanding allows for informed decision-making, while obedience focuses on compliance.
Weber's law is relevant to an understanding of?
Weber's law is relevant to an understanding of how people perceive changes in stimuli, such as light, sound, or weight. It states that the just-noticeable difference between two stimuli is proportional to the magnitude of the stimuli, rather than their absolute value. This law helps explain why we may not notice small changes in a stimulus but can easily detect larger changes.
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 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.

What is the difference between threshold of hearing and absolute threshold of hearing?
The absolute threshold of hearing is the lowest possible tone/decibel you could possibly hear. (This differs form person to person). The Differential Threshold is the point at which a person recognizes the decibel level has changed.Hope this answers your question, just learned this in psychology!
The minimal difference between two stimuli that people can reliably detect?
Difference Threshold
The minimum amount of stimulation required to tell the difference between two stimuli is called the?
An absolute threshold is the smallest detectable level of a stimulus, whereas the just-noticeable difference is the smallest detectable change in two stimuli levels.
What is the difference between 0s and 1s?
The absolute difference is 1.
What is the difference between absolute and incremental encoder?
Nothink there is no difference
What is the difference between absolute temperature scale and kelvin scale urgent I am convinced that there is a difference?
Absolute temperature IS MEASURED IN KELVIN.
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
What is difference between identification threshold and qualification threshold in impurity?
Identification is the act of recognizing objects as a result of remembering them. Qualification is the act of being eligible for something.
