The book is designed as a text for undergraduate and graduate courses in sensory evaluation and as a reference for industrial practitioners. It covers all the basic techniques of sensory testing, from simple discrimination tests to home use placements for consumers. It provides a practical guide to how tests are conducted and, for the reader who wishes a deeper understanding, provides the fundamental psychological and statistical theories that form the basis and rationale for sensory test design. Statistics used in sensory evaluation are demonstrated as integrated applications in the context of appropriate sensory methods and are also presented as a stand-alone material in appendixes. Statistical applications are tailored to common and relevance are obvious, and space is not wasted on designs or analyses that are not suitable for data collection from human observers. The text presents divergent philosophies in a balanced manner. Chapters are constructed so that beginning students who want only practical aspects of conducting sensory tests will find clear instructions on how tests should be conducted. Advanced students and practitioners will profit from the detailed section on rationale and sensory evaluation issues. "It covers the entire spectrum of sensory analysis. I have read many books on this intriguing subject, but this is the Rolls-Royce." a?? Aubrey Parsons, governing council member, International Union for Food Science and Technology
This book will assist practitioners who work with autistic people to comprehend sensory perceptual differences in autism. Strategies for dealing with sensory integration dysfunction are presented in a manner that can easily be understood by practitioners and carers.
Understanding what the consumer wants and will accept are two of the most significant hurdles faced by anyone in new product development. Whether the concern is the proper mouth-feel of a potato chip, the sense of freshness" evoked by a chewing gum, or the weight and texture of a cosmetic, if the consumer doesn't find the product acceptable, it won't sell. Sensory evaluation testing is the process that establishes the consumer acceptability of a product. It can help identify issues before general production is begun and potentially bring to light issues that hadn't previously been considered a factor in the success of the project. Emphasizes the importance of a scientific sensory methodology used to measure and understand consumer perception Illustrates the importance of planning, managing, and communicating product sensory information in a way that is actionable to developers and marketers Presents demonstrated methods for test selection, application and measurement, and testing with the right consumer, including more typical usage environments Includes worked examples for interpreting and displaying results
This is the first modern textbook of sensory ecology in two decades, one of the most popular and rapidly growing subjects in biology. The topic deals with how animals capture (and send) information from their environment, and the sensory systems involved. It investigates the type of information that is gathered by animals, how it is used in a range of behaviours, and the evolution of such traits. Sensory ecology deals with both mechanistic questions (e.g. howsensory receptors capture information from the environment, and how the physical attributes of the environment affect information transmission) and functional questions (e.g. the adaptive significance ofthe information used by the animal to make a decision). Sensory ecology covers the full range of sensory systems and types of sensory information (sound, visual, chemical, magnetic, electric etc.). The latest research has dealt more explicitly with how sensory systems may actually drive evolutionary change, including the formation of new species. This book provides an introduction to the key ideas, theories, and examples, describes how sensory systems work, and explores the links between thesenses, animal signals, behaviour, and evolution.
Do you have a child in your early childhood classroom who: Climbs on top of furniture and jumps off? Covers his ears when children are singing? Refuses to touch clay, paint, or sand? Often falls down and skins his or her knees? Refuses to play on outdoor playground equipment? If so, it is possible this child is having trouble with sensory integration. How can teachers help children with these problems so they can enjoy learning and grow in positive ways? The Sensory Integration Book helps identify children who have difficulties with sensory processing and offers preschool teachers simple, easy-to-use solutions to support the sensory needs of young children in the preschool classroom. Easy-to-implement solutions include adaptations and activities for children with different types of Sensory Processing Disorder. This book has a bonus chapter with instructions on creating low-cost items to help children with sensory issues.
Complying with food regulations and, more importantly, quality standards, requires practical and reliable methods to estimate a product’s shelf life. Emphasizing the importance of the consumer’s perception of when food has reached the end of its shelf life, Sensory Shelf Life Estimation of Food Products provides a tool for adequately predicting sensory shelf life (SSL). The book delineates the basics of sensory analysis and how it applies to shelf-life studies and includes discussions of experimental design aspects, survival analysis methodology, and its extensions. It provides detailed instructions and software functions for performing SSL estimations, accompanied by data sets and the R Statistical Package functions that are available for download. The author presents the cut-off point methodology used to estimate SSL when the survival analysis methods get complicated. He includes a chapter on accelerated storage covering kinetics, calculations of prediction confidence intervals and potential pitfalls. He also examines extensions of survival analysis statistics to other areas of food quality such as optimum concentration of ingredients and optimum cooking temperatures. Microbiologically stable foods, such as biscuits or mayonnaise, will have their shelf-life defined by the changes in their sensory properties. Many fresh foods, such as yogurt or pasta, after relatively prolonged storage may be microbiologically safe to eat but rejected due to changes in their sensory properties. Shelf life in most food products is determined by sensory issues instead of microbiological or chemical concerns. This book offers key techniques for experimental design, storage, consumer testing procedures, and calculations. It includes methods for accelerated storage experiments, thoroughly explains statistical data treatment, and includes practical examples.
Choose the Proper Statistical Method for Your Sensory Data Issue Analyzing Sensory Data with R gives you the foundation to analyze and interpret sensory data. The book helps you find the most appropriate statistical method to tackle your sensory data issue. Covering quantitative, qualitative, and affective approaches, the book presents the big picture of sensory evaluation. Through an integrated approach that connects the different dimensions of sensory evaluation, you’ll understand: The reasons why sensory data are collected The ways in which the data are collected and analyzed The intrinsic meaning of the data The interpretation of the data analysis results Each chapter corresponds to one main sensory topic. The chapters start with presenting the nature of the sensory evaluation and its objectives, the sensory particularities related to the sensory evaluation, details about the data set obtained, and the statistical analyses required. Using real examples, the authors then illustrate step by step how the analyses are performed in R. The chapters conclude with variants and extensions of the methods that are related to the sensory task itself, the statistical methodology, or both.
The third edition of this monograph continues to have the goal of providing an overview of current thought about the spinal cord mechanisms that are responsible for sensory processing. We hope that the book is of value to both basic and clinical neuroscientists. Several changes have been made in the presentation, as well as additions because of the research advances that have been made during the past decade. Chapters 3 and 4 in the previous edition have been subdivided, and now the morphology of primary afferent neu rons of the dorsal root ganglia is described in Chapter 3 and the chemical neuroanatomy of these neurons in Chapter 4. The description of the dorsal horn in the previous Chapter 4 is now included in Chapter 5, and the chemical neuroanatomy of the dorsal horn in Chapter 6. Furthermore, discussions of the descending control systems have now been consolidated at the end of Chapter 12. The authors would like to express their appreciation for the help provided by several individuals. R.E.C. wishes to acknowledge the many things he learned about primary afferent neurons from conversations with Dr S. N. Lawson. He also thanks Lyn Shilling for her assistance with the typing. WDW thanks Dr Nada Lawand for her critical reading of parts of the manuscript, Rosaline Leigh for help with the manuscript, and Griselda Gonzales for preparing the illustrations.
Sensory processing difficulties can lead to puzzling, hard-to-treat emotional and behavioral challenges in children and adolescents. For example, children who can't filter normal background sounds may seem anxious, those oversensitive to touch may seem phobic, and those who seek sensory input may appear hyperactive. Filled with case vignettes, this highly informative guide helps mental health clinicians recognize and address sensory dysregulation that may co-occur with or be misdiagnosed as anxiety disorders, attention-deficit/hyperactivity disorder, and other psychological or behavioral problems. In rich detail, the authors illustrate how to modify cognitive-behavioral therapy and other evidence-based interventions to meet this population's unique needs and make treatment more effective. Reproducible clinical tools can be downloaded and printed in a convenient 8 1/2" x 11" size.
