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 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 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.
Smallest change in sensation that a person can detect is?
The smallest change in sensation that a person can detect is known as the just noticeable difference (JND). This is the smallest difference in stimulation that a person can notice 50% of the time. The JND varies depending on the type of stimulus, with some senses being more sensitive to change than others.
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 sound called above the upper threshold of hearing?
Sound above the upper threshold of hearing is called ultrasound. It is typically defined as sound with frequencies higher than 20,000 Hz, which is the upper limit of human hearing.

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 jnd?
Just Noticeable Difference (JND) The minimal difference that be detected between two similar stimuli is called the differential threshold, or just noticeable difference. In the field of psychophysics, that branch of experimental psychology that studies sensation and perception, a jnd is the amount that something must be changed for the difference to be noticeable, defined to mean that the change is detectable half the time
What does sensation level mean?
The sensation level is measured in decibels. It is frequency specific and starts at 0 dB SL (sensation level) where 0 dB SL is the softest the patient can here a specific frequency. This means that the SL will be different for different people. Everyone's SL will start at 0 but my SL at 1000 Hz may be at 23 db IL and another's may be at 54 db IL.Put more simply, dB SL is the difference between a person's threshold of hearing and the presentation level of a stimulus. If a person's speech reception threshold (SRT) is 10 dB on an audiometer (dB HL) and you present a speech stimulus to them at 50 dB HL on the audiometer, their sensation level would be derived thus: 50 dB (presentation level) minus 10 dB (threshold), which equals a sensation level of 40 dB SL. This is also the procedure for a frequency-specific stimulus (e.g. pure tones): subtract the audiometric threshold (dB HL) from the supra-threshold presentation level (dB HL) and the difference is the sensation level (dB SL).
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.
Smallest change in sensation that a person can detect is?
The smallest change in sensation that a person can detect is known as the just noticeable difference (JND). This is the smallest difference in stimulation that a person can notice 50% of the time. The JND varies depending on the type of stimulus, with some senses being more sensitive to change than others.
The term just noticeable difference is synonymous with?
difference threshold
What is sensation in psychology?
Sensation is defined as the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
What is the weakest stimulus that produces a detectable sensation?
The weakest stimulus that can produce a detectable sensation is known as the absolute threshold. This threshold varies between individuals and can be influenced by factors like attention and motivation. In general, it is the minimum level of stimulation needed for a person to detect a sensory input at least 50% of the time.
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 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
