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.

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 perceptual threshold?
Perceptual threshold refers to the minimum level of stimulus needed for a person to detect a particular stimulus. It is the point at which the stimulus becomes strong enough to be recognized by an individual's senses.
What is the difference between an absolute threshold and a decision threshold?
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.
What is the term for person's tendency to become familiar with a stimulus due to repeated experiences?
The term for a person's tendency to become familiar with a stimulus due to repeated experiences is "habituation." It is a decrease in response to a stimulus after repeated exposure to it.
A subliminal message is one that is presented?
A subliminal message is presented below the threshold of conscious awareness, making it difficult for the recipient to detect or process it consciously. These messages are often used in advertising, media, and psychology to influence attitudes or behaviors without the person being aware of it.

What is the smallest amount of a particular stimulus required to produce any sensation at all in the person to whom the stimulus is presented?
difference threshold
What is the smallest increase or increase in the intensity of a stimulus a person can detect?
just noticeable difference
A stimulus presented to a person or animal that decreases the probability of a particular response is known as?
Punishment by Application
Which theory assumes that top-down processing can influence a person's absolute threshold for a particular stimulus?
Signal detection theory assumes that top-down processing can influence a person's absolute threshold for a particular stimulus. This theory suggests that factors such as individual differences in attention and expectation can impact an individual's ability to detect a stimulus in a noisy environment.
What is perceptual threshold?
Perceptual threshold refers to the minimum level of stimulus needed for a person to detect a particular stimulus. It is the point at which the stimulus becomes strong enough to be recognized by an individual's senses.
What is the absolute 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.
When a person feels heat of a stove is that a stimulus or a response?
I think that it would be a stimulus because response is something you do because of a stimulus.
