The Staircase Procedure for Finding a Perceptual Threshold

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Psychophysics is the name for a set of methods in perceptual psychology designed in order to relate the actual intensity of stimuli to their perceptual intensity. One important aspect of psychophysics involves the measurement of perceptual thresholds: How bright does a light need to be for a person to be able to detect it? How little pressure applied to the skin is detectable? How soft can a sound be and still be heard? Put...

Introduction to z Scores

2023
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one. z scores help...

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of zero.

Rapid Determination of the Thermal Nociceptive Threshold in Diabetic Rats

Here, we describe a rapid reliable and simple procedure to determine the lowest temperature at which rats or mice show nocifensive behavior, i.e. the thermal nociceptive threshold (TNT). This method applies a slowly increasing thermal stimulus allowing precise and reproducible estimation of TNTs with minimum, if any, stress to the animals.
FAQs
Each component contributes a different view of acid exposure. Event count reflects frequency, while event duration reflects persistence; the percentage of time below pH 5.5 summarizes the overall share of the recording affected. Considering these measures together helps clinicians distinguish a pattern of repeated or prolonged acid exposure from a brief, limited change.
Separate upright and supine values preserve the positional context of throat acid exposure. A recording can produce different results during periods spent upright compared with periods spent supine, so each interval is assessed against its corresponding cutoff. This approach prevents one position from obscuring the other and gives clinicians a more specific view of the monitoring pattern.
The commonly used reference cutoffs are greater than 9.41 for upright monitoring and greater than 6.8 for supine monitoring. These values serve as interpretive thresholds rather than universal conclusions. Their meaning depends on the monitoring system used and the patient’s clinical context, so the numerical result should be considered alongside the broader assessment.
A numerical score does not by itself establish the complete clinical meaning of a patient’s throat symptoms. Interpretation also depends on whether the measurement came from upright or supine monitoring, which system generated the result, and the surrounding clinical context. Recognizing these factors helps clinicians avoid treating a cutoff as an independent diagnosis.
Clinicians compare the values from upright and supine periods with their respective reference cutoffs. This comparison shows whether the recorded acid exposure exceeds the commonly used threshold in one position, the other, or both. The resulting pattern supports a more structured assessment of suspected laryngopharyngeal reflux than a single undifferentiated value.
Oropharyngeal pH monitoring can help clinicians assess whether throat symptoms may be associated with reflux reaching the upper airway. The measurements provide objective information for interpreting suspected laryngopharyngeal reflux and can support more consistent diagnostic and treatment decisions. They are therefore relevant when clinical teams evaluate reflux-related symptoms rather than relying on symptoms alone.
