The minimum amount of stimulation a person needs to detect a stimulus 50 percent of the time is called the?
absolute threshold
What is the signal detection theory?
a theory predicting how and when we detect the presence of a faint stimulus ("signal") amid background stimulation ("noise"). Assumes there is no signal absolute threshold and detection depends partly on a person's experience, expectations, motivation, and level of fatigue.
What is an example of a neutral stimulus?
A neutral stimulus is a stimulus that initially produces no specific response other than focusing attention. Examples of a neutral stimulus is a song, an animal, or a flower. If a person that you love gives you a specific flower, creating a pleasant memory, every time you see or smell this specific flower, it brings pleasant memories of that person.
What is the term for person's tendency to become familiar with a stimulus due to repeated experiences?
Habituation
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.

That is called "Absolute threshold"

absolute threshold
The minimum amount of stimulation a person needs to detect a stimulus 50 percent of the time is called the?
absolute threshold
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

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.
How do people experience pain?
A person begins to feel pain when nociceptors in the skin, muscles, or internal organs detect pressure, inflammation, a toxic substance, or another harmful stimulus. The pain message travels along peripheral nerve fibers.

What is a well presented person?
a well presented person is a person who looks and is dressed nicely and appropriatly for their age, talks respectfully and has good "manners"
The amount of time it takes a person to perceive a stimulus and react to it?
reaction time ----a+ foolThe amount of time it takes a person to perceive a stimulus and react to it is averagely 1 to 1.5 seconds.
