Sensory Analysis
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. The discipline requires panels of human assessors, on whom the products are tested, and recording the responses made by them. By applying statistical techniques to the results it is possible to make inferences and insights about the products under test. Most large consumer goods companies have departments dedicated to sensory analysis. Sensory analysis can mainly be broken down into three sub-sections: * Analytical testing (dealing with objective facts about products) * Affective testing (dealing with subjective facts such as preferences) * Perception (the biochemical and psychological aspects of sensation) Analytical testing This type of testing is concerned with obtaining ''objective facts'' about products. This could ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science
Science is a systematic endeavor that Scientific method, builds and organizes knowledge in the form of Testability, testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 Common Era, BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the Universe, physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of History of science in classical antiquity, Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the ...

Discrimination Testing
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. Though useful, these tests typically do not quantify or describe any differences, requiring a more specifically trained panel under different study design to describe differences and assess significance of the difference. Statistical basis The statistical principle behind any discrimination test should be to reject a null hypothesis (H0) that states there is no detectable difference between two (or more) products. If there is sufficient evidence to reject H0 in favor of the alternative hypothesis, HA: There is a detectable difference, then a difference can be recorded. However, failure to reject H0 should not be assumed to be suf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pangborn Sensory Science Symposium
The Pangborn Sensory Science Symposium is a 4–5 days biannual academic conference focusing on sensory and consumer science, named after sensory pioneer Rose Marie Pangborn. Usually, the event has 800–1000 participants and takes place in a different country every uneven year, which is chosen two years in advance. Program The main component of the conference consists of oral presentations given by the attendees. Keynote lectures, interactive workshops, and poster sessions complete the scientific program. Oral and poster presentations are selected by the scientific committee on the basis of submitted contributions, whereas keynote talks are generally by invitation. History The first Pangborn Sensory Science Symposium was held in Järvenpää, Finland in 1993. Since its fifth edition (2003) it has been operated by Elsevier. The journal ''Food Quality and Preference'' is the official supporting publication of the symposia and usually publishes a special issue featuring selected con ...

Focus Group
A focus group is a group interview involving a small number of demographically similar people or participants who have other common traits/experiences. Their reactions to specific researcher/evaluator-posed questions are studied. Focus groups are used in market research to understand better people's reactions to products or services or participants' perceptions of shared experiences. The discussions can be guided or open. In market research, focus groups can explore a group's response to a new product or service. As a program evaluation tool, they can elicit lessons learned and recommendations for performance improvement. The idea is for the researcher to understand participants' reactions. If group members are representative of a larger population, those reactions may be expected to reflect the views of that larger population. Thus, focus groups constitute a research or evaluation method that researchers organize to collect qualitative data through interactive and directed discuss ...

Napping (method Of Data Collection)
A nap is a short period of sleep, typically taken during daytime hours as an adjunct to the usual nocturnal sleep period. Naps are most often taken as a response to drowsiness during waking hours. A nap is a form of biphasic or polyphasic sleep, where the latter terms also include longer periods of sleep in addition to one single period. For years, scientists have been investigating the benefits of napping, including the 30-minute nap as well as sleep durations of 1–2 hours. Performance across a wide range of cognitive processes has been tested. Benefits Sara Mednick conducted a study experimenting on the effects of napping, caffeine, and a placebo. Her results showed that a 60–90-minute nap is more effective than caffeine in memory and cognition. Power nap A power nap, also known as a Stage 2 nap, is a short slumber of 20 minutes or less which terminates before the occurrence of deep slow-wave sleep, intended to quickly revitalize the napper. The power nap is meant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Choice Profiling
Free-choice profiling is a method for determining the quality of a thing by having a large number of subjects experience (view, taste, read, etc.) it and then allowing them to describe the thing in their own words, as opposed to posing them a set of "yes-no-maybe" questions. All of the descriptions are then analyzed to determine a " consensus configuration" of qualities, usually through Generalized Procrustes analysis (GPA) or Multiple factor analysis Multiple factor analysis (MFA) is a Factorial experiment, factorial method devoted to the study of tables in which a group of individuals is described by a set of variables (quantitative and / or qualitative) structured in groups. It is a Multivaria ... (MFA). Free-choice profiling first emerged in 1984 but the original published model has been modified by researchers into variations that are more applicable to their particular use. For example, a technique employed by Jean Marc Sieffermann combined it with flash profiling, specifically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantitative Descriptive Analysis
Developed by Tragon Corporation in 1974, Quantitative Descriptive Analysis (QDA) is a behavioral sensory evaluation 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 consum ... 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. Sensory evaluation is a science that measures, analyzes, and interprets the reactions of the senses of sight, smell, sound, taste, and texture (or kinesthesis) to products. It is a people science; i.e., people are essential to obtain information about products. Tragon QDA is a registered trademark with the United States Patent and Trademark Office. The term was coined by Herbert Stone (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insights
Insight is the understanding of a specific cause and effect within a particular context. The term insight can have several related meanings: *a piece of information *the act or result of understanding the inner nature of things or of seeing intuitively (called noesis in Greek) *an introspection *the power of acute observation and deduction, discernment, and perception, called intellection or noesis *An understanding of cause and effect based on the identification of relationships and behaviors within a model, context, or scenario (see artificial intelligence) An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word '' Aha-Erlebnis''. The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany, eureka moment or (for cross word solvers) the penny dropping moment (PDM). Sudden sickening realisations often identify a problem rather than solving it, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Design
The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which natural conditions that influence the variation are selected for observation. In its simplest form, an experiment aims at predicting the outcome by introducing a change of the preconditions, which is represented by one or more independent variables, also referred to as "input variables" or "predictor variables." The change in one or more independent variables is generally hypothesized to result in a change in one or more dependent variables, also referred to as "output variables" or "response variables." The experimental design may also identify control variables that must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
