Absolute threshold: See stimulus threshold.
Acceptance measurement: Consumer test to determine the acceptance of (new) products. Generally involves a comparison of new products with those already on the market.
Acquired preferences: Preferences which are acquired during life as a result of learning or conditioning processes.
Adaptation: Ability of a sense to show a change in perception as a result of the continuing effect of a constant stimulus; the stimulus threshold of the affected sense becomes adapted to the stimulus intensity level.
Adaptive response: An appropriate action in which the individual responds successfully to some environmental demand. Adaptive responses require good sensory integration, and they also further the sensory integrative process.
Additivity: Addition effect of sensory impressions in a mixture so that the perceived overall intensity is equal to the sum of the intensity of the single components.
Affective tests: Tests to evaluate the popularity of an aroma and/or taste impression (also called hedonic tests).
Aftertaste: Sensory impression that lasts longest after swallowing.
Analysis of variance: Multivariate statistical method. An independent variable Y, one or more independent variables X. Are there X differences between the products for term Y?
Analytical testing: See objective testing. nosmia: Olfactory disorder resulting in temporary or permanent loss of smell.
Appearance: Characteristics that encompass all visually perceptible sensory impressions of a food. Examples include shape, surface, structure, colour, lustre, clarity, cloudiness, opalescence.

Sensory Perception

...Critical Thinking PHI 210: Sensory Perception Sherman Woodard July 09, 2012 Professor Dr. Charles Fleming Strayer University Three reasons for believing in the accuracy or inaccuracy of sensory information is perception, interpretation, and knowledge. Perception is our sensory experience of the world around us and involves both the recognition of environmental stimuli and actions in response to these stimuli (Bagley, 2004). Through the perceptual process, we gain information about properties and elements of the environment that are critical to our survival. Perception not only creates our experience of the world around us, and it also allows us to act within our environment. Interpretation is a communication process, designed to reveal meanings, and relationships of our cultural and natural heritage, through involvement with objects, artifacts, landscapes and sites. Interpretation is how we perceive certain situations through our own thoughts and beliefs. Knowledge is a familiarity with someone or something, which can include facts, information, descriptions, or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject), and it can be more or less formal or systematic. The definitions of perception, interpretation, and knowledge are closely entwined when it comes to the accuracy......

The Interpretation of the Definition of the Word Courage

...Topic: The interpretation of the definition of the word “Courage”. Essay Questions: What feelings does the word courage provoke in you? How courage is traditionally interpreted? How important is courage for any personality type? Thesis Statement: The definitions of this word are numerous, but since the world around us changes the definitions change, too. For instance, if we talk about the liberty of word we can define “courage” as the person’s ability to say what he thinks on this matter. Courage, what feelings do you get when you hear this word? Do you feel Inspiration, Admiration, Respect, Fear, or maybe nothing at all? To some people courage is just another word, and for others it means so much more. The word courage comes from the Latin word coraticum. The root”cor” means heart. Then after the world entered English through French it was completed with an English suffix- age, which expressed action or the result of action. So the word courage really means an action that comes from the heart, in other words it is a noble action. How is this word used by contemporary people? The main usage of this term of this term of the word is, to describe people who have a type of mind that allows them not to think rational, and face danger without fear. Which is also referred to as bravery or boldness? This word is usually used when talking about man, because from its original form it was considered to be more of manly virtue. The definitions of this word are numerous, but......

Sensory Perception

...Sensory Perceptions Victoria Shelton Strayer University PHI 210 Joel Goldstein January 25, 2013 Sensory Perceptions Reasons for believing in the accuracy of sensory information What is sensory perception? Sensory perception is the events or occurrences in the environment a person takes in, processes and understands through their five senses. Three reasons for believing in the accuracy or inaccuracy of sensory information is perception, interpretation, and knowledge. In the words of Jacques Barzun, “In ordinary speech the words perception and sensation tend to be used interchangeably, but the psychologist distinguishes. Sensations are the items of consciousness—a color, a weight, a texture—that we tend to think of as simple and single. Perceptions are complex affairs that embrace sensation together with other, associated or revived contents of the mind, including emotions (Barzun, 1907).” Perception is the organization, identification and interpretation of sensory information in order to represent and understand the environment (2003). This is as a result of organizing and interpreting information that is gained from our five senses which we use on a daily basis. Our senses can be helpful to us in many ways by providing our brains with the right information, or harmful by making our minds play tricks on us. The accuracy of this information that is taken in varies because of many different reasons. Sensory information is gained as first-hand......

...Definitions A definition is a statement that gives the meaning of a concept. For simple and relatively concrete concepts such as ‘Table’ we can understand them without definitions by simply seeing them. But most concepts are abstract and complex and to understand them definitions are important tool of knowledge. A definition does the following functions: a. It clarifies the boundaries of a concept. b. It clarifies the relationships among concepts. c. It clarifies the referents of the concepts. Vagueness and Ambiguity A term is ‘vague’ means it is hazy obscure and imprecise for example the words love, happiness, rich or poor are vague. We can rarely tell whether they apply to a given situation or not. How rich one has to be in order to be called rich? An ‘ambiguous expression’ is one that can be interpreted as having more than one clearly distinct meaning in a given context for example: words such as proper, light, critical, bank can be used ambiguously. If one were to describe an action as proper, does this mean proper in moral sense or proper in the sense of being socially acceptable? The difference between ambiguity and vagueness is that vague terminology allows for a relatively continuous range of interpretations, where as ambiguous terminology allows for multiple discrete interpretations. A vague expression creates a blur of meaning where as ambiguous expression mixes up otherwise clear meanings. Definitions and their purposes Definition is a......

How Is the Word Myth Used Popularly

...Luis R. Vazquez Jr. World Mythology HUM/105 1. How is the word myth used popularly? For example, what does the statement, “It’s a myth” mean? In contrast, how is the word myth used in the academic context? After considering the definition in your textbooks and course materials, write a definition in your own words. Well, the word myth brings to my mind fantasy tale of good and evil and how good wins over evil. I was reading the material’s for the class but however it has brought me to a new form of thinking. For me it was like playing in the woods as a child with my older brother and younger sister they would say to me to the boogey scare, I would hurry and run home scared out my mind, crying to my mother to help me and she would tell me that “it’s just a myth”, there is no boogey man. So then I learned that a myth was what I would say people who tell lies. I live in this world of 2013, which knowing the facts are a way better of understanding the differences of a myths and the facts are the truth. Seems like if a story is recorded on film and in the least a scientist can have fun in explaining of the unexplained in the stories told. I think the best way to look at the stories of myths is to have an open mind and not a close one (naïve’) so to speak. 2. Why do myths from different cultures around the world address such similar or universal themes? Think about how myths explain the unknown and the tribulations of mankind. By reading the textbook,......

Sensory Science: Electronic Noses

...NAME LYNETTE CHIRIDZA COURSE SENSORY SCIENCE PROGRAM FOOD PROCESSING TECHNOLOGY LECTURER MR MPOFU ASSIGNMENT ONE QUESTION Describe and explain the working principle of electronic noses and their application in the food industry. ANSWER Analysis of odour and flavour in food has traditionally been performed either by a trained sensory panel or by head-space gas chromatography mass spectrometry. These methods are time consuming and costly and there is need in the food industry for objective automated non-destructive techniques that can characterize odour and flavour in food. New methods should allow a high number of samples to be analysed within a short period of time with a sufficient reproducibility and accuracy. During recent years there has been a rapid development of a concept named electronic nose (artificial nose) based on chemical gas-sensor array technology which seems to fulfil these requirements (Russell et al, 2001) The principle of operation of electronic noses is simple. Headspace gas from a sample is introduced to an array of sensors, which will respond to different degrees depending on the nature of the organic compounds present. The electronic nose derived its name because it in several aspects tries to resemble the human nose. Human olfactory perception is based on chemical interaction between volatile odour compounds and the olfactory receptors in the nasal cavity. The signals generated are transferred to the brain...

BY ED M. WOOD When I left university I felt like I was bursting through a set of saloon swing doors, arms loaded with qualifications about to hold up the professional world until they handed over the job of my dreams. I think many graduates feel like this, and this misplaced confidence compounds the disappointment when the professional world shrugs its collective shoulders. My reaction to this disappointment was to turn my back on the opportunity vacuum and stock up on soft skills. I googled for TEFL courses in Spain, found a charming townlet called Zamora in Castilla y Leon and booked myself a one-way ticket. My Spanish education, albeit informal, started almost as soon as we touched down. I was tasked with navigating my way across Madrid weighed down by my backpack and an oppressive, immovable mid-summer mugginess. Your relationship with new words is shaped to some extent by the context in which you learn them. Whenever I hear words like estación de trenes (train station), vía (track) and billete (ticket), images of hulking, dusty mazes of misinformation arise in bubbles of residual dread. I......

The Larry Richards Reader includes a listing by Stuart Umpleby of notable definitions:[6] * "Science concerned with the study of systems of any nature which are capable of receiving, storing and processing information so as to use it for control." — A. N. Kolmogorov * "The art of securing efficient operation." — Louis Couffignal[7] * "'The art of steersmanship': deals with all forms of behavior in so far as they are regular, or determinate, or reproducible: stands to the real machine -- electronic, mechanical, neural, or economic -- much as geometry stands to real object in our terrestrial space; offers a method for the scientific treatment of the system in which complexity is outstanding and too important to be ignored." — W. Ross Ashby * "A branch of mathematics dealing with problems of control, recursiveness, and information, focuses on forms and the patterns that connect." — Gregory Bateson * "The art of effective organization." — Stafford Beer * "The art and science of manipulating defensible metaphors." — Gordon Pask * "The art of creating equilibrium in a world of constraints and possibilities." — Ernst von Glasersfeld * "The science and art of understanding." — Humberto Maturana * "The ability to cure all temporary truth of eternal triteness." — Herbert......

Definitions and Attitudes in Political Science

...1. What is your personal definition of politics? My personal definition of politics is a system (tacit, explicit or both) by which a subset of a population represents or governs the population (or both). I think it is only applications of this definition that vary widely. 2. What do you think are examples of political behaviours? To what extent do you engage in these behaviours in your own life? How different are these types of behaviour from what you perceive to take place in our municipal, provincial, and federal institutions? Political behaviours are essentially the private citizen stepping outside of their personal or professional life to engage in a behaviour, activity, instance or process that will affect or factor into the policy making process of the community, city or country, to whatever very small extent. In my opinion political behaviour may also amount to the expression of a view with a situation or a view regarding a suggested change or action in the decision making of the political establishment. In our democracy, the right, even the moral responsibility to participate in elections is an example of this. Speech making, volunteer work, participating in electoral campaigns, writing to the newspapers or even leaving comments on the Internet sites of newspapers, may all be considered political behaviours. I do not engage in political behaviours to a considerable extent; my extent is negligible. Often it is all I do to leave comments on the Internet......

Sensory Adaptation

...Sensory Adaptation Jessica Munden American Intercontinental University Abstract This paper will define and explain the concept of sensory adaptation. Three experiments were conducted to show sensory adaptation. This paper will report the experiments findings by illustrating what was experienced during the experiment. This paper will also discuss how adaptation is important from an evolutionary perspective. Sensory Adaptation Chemical senses, such as taste and smell, and the skin can be affected by sensory adaptation. It is important to understand the systems related to the chemical senses and the skin in order to understand how they can be affected by sensory adaptation. Three experiments were conducted to help explain sensory adaptation, which will appear later. Sensory Adaptation is defined in Words of Wisdom (2011) as “the process by which senses become less responsive to particular stimuli." In other words, when certain stimulus is continued the brain's sensory responses become less responsive. Adaptation affects the sensory systems, which include the five senses vision, taste, smell, hearing, and touch. When a non-smoker walks into a home, in which a person smokes inside, the smell of nicotine will be overwhelming. After spending some time in the home the smell of nicotine will seem to dissipate because one's system will adapt to the smell (Words of Wisdom, 2011). An experiment was conducted to show sensory adaptation to touch. During this experiment, one......
