The absolute threshold for vision refers to the minimum intensity of light that can be detected by the human eye under ideal conditions. This threshold varies between individuals and can be influenced by factors such as lighting conditions and the observer's sensitivity. Typically, it is estimated that the absolute threshold for vision is the detection of a single photon of light in complete darkness, although in practical terms, it may require slightly more light for reliable detection. This threshold is fundamental to understanding sensory perception and how we interact with our visual environment.
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.
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.
The Lurker at the Threshold was created in 1945.
Absolute threshold is the smallest level of energy required by an external stimulus to be detectable by the human senses, including vision, hearing, taste, smell and touch
The absolute threshold is the smallest amount of light that a person can detect. The human absolute threshold we can detect is a candle flame at 30 miles away.
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.
Taste threshold is the minimum concentration of a substance needed for a person to detect a taste. It varies depending on the individual's sensitivity to flavors and can be influenced by factors such as age, genetics, and health conditions.

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.
An example of an absolute threshold is the minimum amount of light that a person can detect in a dark room. This is the point at which the person first becomes aware of the presence of light.
A. absolute. The threshold for detecting an auditory signal is known as the absolute threshold, which refers to the minimum intensity of a sound that can be detected by the human ear.
The absolute threshold of vision is being able to see a candle flame from 30 miles on a clear dark night. This the absolute threshold under normal conditions and they vary according to the level and nature of ongoing sensory stimulation and varies from person to person and moment to moment.
Your question is meaningless, there is either an absolute logation (x/y point) or an approximate location(near the house on the corner), there can not be an "approximate absolute" location.
