A preference test is an experiment in which animals are allowed free access to multiple environments which differ in one or more ways. Various aspects of the animal's behaviour can be measured with respect to the alternative environments, such as latency and frequency of entry, duration of time spent, range of activities observed, or relative ...
Sensory analysis (or sensory evaluation) is a scientific discipline that applies principles of experimental design and statistical analysis to the use of human senses (sight, smell, taste, touch and hearing) for the purposes of evaluating consumer products. This method of testing products is generally used during the marketing and advertising ...
The hedonic scale is a sensory evaluation tool used to measure the degree of pleasure or liking of a product or service. The scale usually consists of 9 levels ranging from 1 to 9, or "dislike extremely" to "like extremely". [1] The hedonic scale is widely used for consumer acceptance testing. [2] [3]
Developed by Tragon Corporation in 1974, Quantitative Descriptive Analysis (QDA) is a behavioral sensory evaluation approach that uses descriptive panels to measure a product's sensory characteristics. Panel members use their senses to identify perceived similarities and differences in products, and articulate those perceptions in their own words.
Sensometrics is a scientific discipline that involves the application of mathematical, statistical, and computational methods to the field of Sensory and Consumer Science. It is an interdisciplinary field, closely related to disciplines such as sensory evaluation, statistics, psychometrics, and chemometrics, among others. Sensometrics deals ...
The Just-About-Right scale (JAR scale), is a sensory evaluation tool used to measure the intensity of a particular attribute or characteristic of a product or service. The JAR scale typically consists of 5 levels ranging from "Much too little" to "Much too much."
In the preference testing phase, the animal is allowed unrestricted access to all compartments of the apparatus. [17] During the test, the time a subject spends in each compartment is measured in seconds. [16] Modern protocols utilize commercial automated tracking systems to measure the time; however, manual measurement is also used.
Sensory testing can quantify and assess the swelling for better treatment. The strength of the air pulse given during sensory testing in acid-injured vocal cords due to acid reflux disease will necessarily be much greater in order to elicit an airway reflex than tissues that are not swollen.
