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]
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.
Discrimination testing is a technique employed in sensory analysis to determine whether there is a detectable difference among two or more products. The test uses a group of assessors (panellists) with a degree of training appropriate to the complexity of the test to discriminate from one product to another through one of a variety of experimental designs.
Howard-Dolman test. Stereoacuity [1] is most simply explained by considering one of its earliest test, a two-peg device, named Howard-Dolman test after its inventors: [2] The observer is shown a black peg at a distance of 6m (=20 feet). A second peg, below it, can be moved back and forth until it is just detectably nearer than the fixed one.
The hedonic music consumption model was created by music researchers Kathleen Lacher and Richard Mizeski in 1994. Their goal was to use this model to examine the responses that listening to rock music creates, and to find if these responses influenced the listener's intention to later purchase the music. [ 1 ]
The felicific calculus could in principle, at least, determine the moral status of any considered act. The algorithm is also known as the utility calculus, the hedonistic calculus and the hedonic calculus. To be included in this calculation are several variables (or vectors), which Bentham called "circumstances". These are:
Emotion is defined as any mental experience with high intensity and high hedonic content. [1] The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms.
The use of the term in psychology entered English with the translation from German ("Valenz") in 1935 of works of Kurt Lewin.The original German word suggests "binding", and is commonly used in a grammatical context to describe the ability of one word to semantically and syntactically link another, especially the ability of a verb to require a number of additional terms (e.g. subject and ...
