Available in PDF, EPUB and Kindle. Book excerpt: Measurement of visual acuity has been the cornerstone of visual testing since Snellen began quantitating visual acuity using letter optotypes in the 1860s. Bjerrum in the 1880s brought sophistication and quantitation to the assessment of the visual field with tangent screen examination using differently sized and colored targets. Further advances in visual testing did not occur until the Goldmann perimeter and the Farnsworth Munsell 100 Hue test were introduced in the 1940s, permitting further refinement in the detection and quantitation of acquired visual loss. An explosion of interest in sensory visual function testing followed the demonstration by Quigley and his colleagues in 1982 that despite the loss of more than 40% of the axons in the optic nerve, Snellen acuity and kinetic perimetry remained normal. Much of this interest has focused on a search for more sensitive and disease-specific sensory visual tests. Previously, novel tests used to probe visual function remained in the province of the visual physiologist and psychophysicist. These tests are now being introduced by the ophthalmologist into clinical practice. Concomitantly, the mass production of microcomputers and other technical advances have made tests such as automated perimetry and visual evoked response testing affordable for most offices. The clinician is presently being inundated with a plethora of visual function tests that may require a knowledge of visual psychophysics and statistics to understand and interpret. The purpose of this book is to acquaint the clinician with these new tests so that they may be used to maximum benefit.

Download or read book Visual Impairments written by National Research Council and published by National Academies Press. This book was released on 2002-08-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.

Download or read book A Handbook for Sensory and Consumer Driven New Product Development written by Maurice O'Sullivan and published by Woodhead Publishing. This book was released on 2016-09-16 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Handbook for Sensory and Consumer Driven New Product Development explores traditional and well established sensory methods (difference, descriptive and affective) as well as taking a novel approach to product development and the use of new methods and recent innovations. This book investigates the use of these established and new sensory methods, particularly hedonic methods coupled with descriptive methods (traditional and rapid), through multivariate data analytical interfaces in the process of optimizing food and beverage products effectively in a strategically defined manner. The first part of the book covers the sensory methods which are used by sensory scientists and product developers, including established and new and innovative methods. The second section investigates the product development process and how the application of sensory analysis, instrumental methods and multivariate data analysis can improve new product development, including packaging optimization and shelf life. The final section defines the important sensory criteria and modalities of different food and beverage products including Dairy, Meat, Confectionary, Bakery, and Beverage (alcoholic and non-alcoholic), and presents case studies indicating how the methods described in the first two sections have been successfully and innovatively applied to these different foods and beverages. The book is written to be of value to new product development researchers working in large corporations, SMEs (micro, small or medium-sized enterprises) as well as being accessible to the novice starting up their own business. The innovative technologies and methods described are less expensive than some more traditional practices and aim to be quick and effective in assisting products to market. Sensory testing is critical for new product development/optimization, ingredient substitution and devising appropriate packaging and shelf life as well as comparing foods or beverages to competitor's products. - Presents novel and effective sensory-based methods for new product development - two related fields that are often covered separately - Provides accessible, useful guidance to the new product developer working in a large multi-national food company as well as novices starting up a new business - Offers case studies that provide examples of how these methods have been applied to real product development by practitioners in a wide range of organizations - Investigates how the application of sensory analysis can improve new product development including packaging optimization
Download or read book The Neurology of Vision written by Jonathan D. Trobe and published by Oxford University Press. This book was released on 2001-03-29 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neurology of Vision sets out the principles and information needed to understand and manage disorders of the visual pathways in the brain. The author divides vision into three components. The optical component addresses the eye's ability to properly focus light on the retina. The retinocortical component converts light into neural signals in the retina, transmitting them to the primary visual cortex. Finally, the integrative component converts this simple visual information into more complicated forms. The symptoms and signs, testing methods, and diseases of each part of the visual system are presented using this unique, structural component approach. A final chapter discusses the visual manifestations of psychiatric disturbances. The book is heavily illustrated with over 150 beautifully rendered line illustrations, 50 radiographic brain images, and 60 retinal photographs. Case studies with teaching questions are also included, to further the reader's knowledge and test understanding.

Available in PDF, EPUB and Kindle. Book excerpt: This Second Edition of Sensory Evaluation Practices provides the background and understanding necessary to make informed decisions about managing a sensory evaluation program, designing tests, and interpreting and reporting results. The authors have been in the sensory management consulting business for more than 20 years and bring their expertise to the enthusiastic and comprehensive revision of this invaluable book. Sensory evaluation of a product is the measurement of what is perceived about that product—not only in terms of its efficacy, but also by the more subtle influences of sight, smell, taste, touch, and where applicable, sound. A key benefit from this exciting and quantitative science is cost reduction in product reformulation due to the ability to evaluate a product's consumer acceptance in the marketplace. - Reveals changes in the field, particularly in the business view of sensory evaluation as a product information source - Clarifies the relationships between product specialists/experts and sensory panels, between sensory and market research , and between study of perception and sensory evaluation of products - Includes discussion of test requests and their "hidden agenda" product selection, and the relative merits of testing products from different (laboratory, pilot plant, production) sources - Introduces two new methods of quantitative descriptive analysis and an investigation of the merits of product specific versus global panels - Discusses affective testing and the advantages of various methods including testing with children, the interaction between sensory and market research, the use of employees versus non-employees, and the effect of the number of judgments on product decisions

Download or read book Sensory Evaluation of Food Principles and Practices written by Harry T. Lawless and published by Springer Science & Business Media. This book was released on 1999-08-31 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
