| definition of threshold in psychology: Sensory Evaluation of Food Harry T. Lawless, Hildegarde Heymann, 2010-09-27 The ?eld of sensory science has grown exponentially since the publication of the p- vious version of this work. Fifteen years ago the journal Food Quality and Preference was fairly new. Now it holds an eminent position as a venue for research on sensory test methods (among many other topics). Hundreds of articles relevant to sensory testing have appeared in that and in other journals such as the Journal of Sensory Studies. Knowledge of the intricate cellular processes in chemoreception, as well as their genetic basis, has undergone nothing less than a revolution, culminating in the award of the Nobel Prize to Buck and Axel in 2004 for their discovery of the olfactory receptor gene super family. Advances in statistical methodology have accelerated as well. Sensometrics meetings are now vigorous and well-attended annual events. Ideas like Thurstonian modeling were not widely embraced 15 years ago, but now seem to be part of the everyday thought process of many sensory scientists. And yet, some things stay the same. Sensory testing will always involve human participants. Humans are tough measuring instruments to work with. They come with varying degrees of acumen, training, experiences, differing genetic equipment, sensory capabilities, and of course, different preferences. Human foibles and their associated error variance will continue to place a limitation on sensory tests and actionable results. Reducing, controlling, partitioning, and explaining error variance are all at the heart of good test methods and practices. |
| definition of threshold in psychology: Puppy Socialization Marge Rogers, Eileen Anderson, 2021-06-23 Puppy Socialization: What It Is and How to Do It defines and demystifies the most important thing you can do for your puppy: socialization. The authors don't just tell you what you need to know about socialization. They show you with dozens of photographs and exclusive linked videos (a live internet connection is needed to view the videos). You'll see other owners socialize their puppies under the guidance of a nationally certified dog trainer and behavior consultant. These real-life examples of socialization show you what to do when things go well and when they don't go so well. You’ll learn about: • The magical time. Did you know that there is a special time in a puppy's life when he is primed to accept new things? The authors tell you when that time is, when that socialization window starts closing, and how a little effort by an owner during that time can save heartache later. • Canine body language. Puppies and dogs are talking all the time—with their body language. Learn to tell when a puppy or dog is relaxed and happy, a bit nervous about something, or outright fearful. • Myth-busting. There's a lot of advice out there about socialization and not all of it is good. Some common myths can actually cause a puppy harm. The authors give you the most up-to-date information on puppy socialization and put some harmful myths to rest. • Socializing a puppy during COVID-19. Puppies have so much to get used to: people, environments, noises, and more. The authors provide strategies for keeping humans and puppies safe while socializing puppies, even during the COVID-19 pandemic. • What supplies are needed during socialization. The authors provide checklists of things owners need when socializing a puppy at home and away from home. |
| definition of threshold in psychology: Introduction to Psychology Jennifer Walinga, Charles Stangor, This book is designed to help students organize their thinking about psychology at a conceptual level. The focus on behaviour and empiricism has produced a text that is better organized, has fewer chapters, and is somewhat shorter than many of the leading books. The beginning of each section includes learning objectives; throughout the body of each section are key terms in bold followed by their definitions in italics; key takeaways, and exercises and critical thinking activities end each section. |
| definition of threshold in psychology: Visual Perception Tom Cornsweet, 2012-12-02 Visual Perception explores fundamental topics underlying the field of visual perception, including the perception of brightness and color, the physics of light, and the optics of the eye. Although the text leans heavily on physical and physiological concepts, explanations of the relevant physics and physiology are considered. This book is organized into 16 chapters and begins with an overview of the relationship between information assimilation and the physiology of the visual system based on data gathered both in physiological and perceptual experiments. More specifically, this text discusses the nature of the human perceptual system in terms of the kinds of information that are assimilated from the world, and how this selection of information is governed by the structure of receptors and the neural circuits that are connected to them. The relationships between symbols and their corresponding physical and physiological variables are also examined. Finally, the book addresses the presence of strong lateral inhibition in the visual system and how it fits the concept of evolution. This book is aimed at undergraduate and graduate students, regardless of their academic backgrounds. |
| definition of threshold in psychology: The 4 Stages of Psychological Safety Timothy R. Clark, 2020-03-03 This book is the first practical, hands-on guide that shows how leaders can build psychological safety in their organizations, creating an environment where employees feel included, fully engaged, and encouraged to contribute their best efforts and ideas. Fear has a profoundly negative impact on engagement, learning efficacy, productivity, and innovation, but until now there has been a lack of practical information on how to make employees feel safe about speaking up and contributing. Timothy Clark, a social scientist and an organizational consultant, provides a framework to move people through successive stages of psychological safety. The first stage is member safety-the team accepts you and grants you shared identity. Learner safety, the second stage, indicates that you feel safe to ask questions, experiment, and even make mistakes. Next is the third stage of contributor safety, where you feel comfortable participating as an active and full-fledged member of the team. Finally, the fourth stage of challenger safety allows you to take on the status quo without repercussion, reprisal, or the risk of tarnishing your personal standing and reputation. This is a blueprint for how any leader can build positive, supportive, and encouraging cultures in any setting. |

| definition of threshold in psychology: Emergent Techniques for Assessment of Visual Performance National Research Council, 1985-01-01 Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function. |
| definition of threshold in psychology: Threshold Spaces Till Boettger, 2014-09-25 What is a threshold space? A prelude, an intermediate space, a barrier? Inside or outside? The threshold space is all of these, usually even at the same time. He lives on the spatial ambivalence between opening and closing and at the same time creates the expectation of what is to come. Till Boettger has dealt in teaching and research projects closely with the architectural staging of arrival and reception. His book is a collection of exemplary phenomenological analyzes of spatial transitions in historical and modern cultural buildings by renowned architects. It also develops a methodology to optimize threshold rooms in all construction projects. In addition to a balance that can generate an exciting space, there is also primarily the temporal sequence of experiencing determining. Threshold spaces are shown here in their role as a spatial agent: they receive and bid farewell. |

| definition of threshold in psychology: Perceptual Organization Michael Kubovy, James R. Pomerantz, 2017-03-31 Originally published in 1981, perceptual organization had been synonymous with Gestalt psychology, and Gestalt psychology had fallen into disrepute. In the heyday of Behaviorism, the few cognitive psychologists of the time pursued Gestalt phenomena. But in 1981, Cognitive Psychology was married to Information Processing. (Some would say that it was a marriage of convenience.) After the wedding, Cognitive Psychology had come to look like a theoretically wrinkled Behaviorism; very few of the mainstream topics of Cognitive Psychology made explicit contact with Gestalt phenomena. In the background, Cognition's first love – Gestalt – was pining to regain favor. The cognitive psychologists' desire for a phenomenological and intellectual interaction with Gestalt psychology did not manifest itself in their publications, but it did surface often enough at the Psychonomic Society meeting in 1976 for them to remark upon it in one of their conversations. This book, then, is the product of the editors’ curiosity about the status of ideas at the time, first proposed by Gestalt psychologists. For two days in November 1977, they held an exhilarating symposium that was attended by some 20 people, not all of whom are represented in this volume. At the end of our symposium it was agreed that they would try, in contributions to this volume, to convey the speculative and metatheoretical ground of their research in addition to the solid data and carefully wrought theories that are the figure of their research. |
| definition of threshold in psychology: The Consolation of Philosophy (Sedgefield translation) Anicius Manlius Severinus Boethius, 2022-11-13 Consolation of Philosophy (Latin: Consolatio Philosophiae) is a philosophical work by Boethius, written around the year 524. It has been described as the single most important and influential work in the West on Medieval and early Renaissance Christianity, and is also the last great Western work of the Classical Period. Anicius Manlius Severinus Boëthius, commonly called Boethius (c. 480–524 or 525 AD), was a philosopher of the early 6th century. He was born in Rome to an ancient and prominent family which included emperors Petronius Maximus and Olybrius and many consuls. His father, Flavius Manlius Boethius, was consul in 487 after Odoacer deposed the last Western Roman Emperor. Boethius, of the noble Anicia family, entered public life at a young age and was already a senator by the age of 25. Boethius himself was consul in 510 in the kingdom of the Ostrogoths. In 522 he saw his two sons become consuls. Boethius was imprisoned and eventually executed by King Theodoric the Great, who suspected him of conspiring with the Eastern Roman Empire. While jailed, Boethius composed his Consolation of Philosophy, a philosophical treatise on fortune, death, and other issues. The Consolation became one of the most popular and influential works of the Middle Ages. |

| definition of threshold in psychology: Bayesian Cognitive Modeling Michael D. Lee, Eric-Jan Wagenmakers, 2014-04-03 Bayesian inference has become a standard method of analysis in many fields of science. Students and researchers in experimental psychology and cognitive science, however, have failed to take full advantage of the new and exciting possibilities that the Bayesian approach affords. Ideal for teaching and self study, this book demonstrates how to do Bayesian modeling. Short, to-the-point chapters offer examples, exercises, and computer code (using WinBUGS or JAGS, and supported by Matlab and R), with additional support available online. No advance knowledge of statistics is required and, from the very start, readers are encouraged to apply and adjust Bayesian analyses by themselves. The book contains a series of chapters on parameter estimation and model selection, followed by detailed case studies from cognitive science. After working through this book, readers should be able to build their own Bayesian models, apply the models to their own data, and draw their own conclusions. |

The most elegant design can fail if it forces users to conform to the design rather than working within the blueprint of how humans perceive and process the world around them. This practical guide explains how you can apply key principles in psychology to build products and experiences that are more intuitive and human-centered. Author Jon Yablonski deconstructs familiar apps and experiences to provide clear examples of how UX designers can build experiences that adapt to how users perceive and process digital interfaces. You’ll learn: How aesthetically pleasing design creates positive responses The principles from psychology most useful for designers How these psychology principles relate to UX heuristics Predictive models including Fitts’s law, Jakob’s law, and Hick’s law Ethical implications of using psychology in design A framework for applying these principles |
| definition of threshold in psychology: Visual Psychophysics Zhong-Lin Lu, Barbara Dosher, 2013-10-11 A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science. |

| definition of threshold in psychology: Detection Theory Neil A. Macmillan, C. Douglas Creelman, 2004-09-22 Detection Theory is an introduction to one of the most important tools for analysis of data where choices must be made and performance is not perfect. Originally developed for evaluation of electronic detection, detection theory was adopted by psychologists as a way to understand sensory decision making, then embraced by students of human memory. It has since been utilized in areas as diverse as animal behavior and X-ray diagnosis. This book covers the basic principles of detection theory, with separate initial chapters on measuring detection and evaluating decision criteria. Some other features include: *complete tools for application, including flowcharts, tables, pointers, and software; *student-friendly language; *complete coverage of content area, including both one-dimensional and multidimensional models; *separate, systematic coverage of sensitivity and response bias measurement; *integrated treatment of threshold and nonparametric approaches; *an organized, tutorial level introduction to multidimensional detection theory; *popular discrimination paradigms presented as applications of multidimensional detection theory; and *a new chapter on ideal observers and an updated chapter on adaptive threshold measurement. This up-to-date summary of signal detection theory is both a self-contained reference work for users and a readable text for graduate students and other researchers learning the material either in courses or on their own. |

His findings form the basis of Please Understand Me II, an updated and greatly expanded edition of the book, far more comprehensive and coherent than the original, and yet with much of the same easy accessibility. One major addition is Keirsey's view of how the temperaments differ in the intelligent roles they are most likely to develop. Each of us, he says, has four kinds of intelligence, tactical, logistical, diplomatic, strategic, though one of the four interests us far more than the others, and thus gets far more practice than the rest. Like four suits in a hand of cards, we each have a long suit and a short suit in what interests us and what we do well, and fortunate indeed are those whose work matches their skills. As in the original book, Please Understand Me II begins with The Keirsey Temperament Sorter, the most used personality inventory in the world. But also included is The Keirsey Four-Types Sorter, a new short questionnaire that identifies one's basic temperament and then ranks one's second, third, and fourth choices. Share this new sorter with friends and family, and get set for a lively and fascinating discussion of personal styles. |

Master your mental strength—revolutionary new strategies that work for everyone from homemakers to soldiers and teachers to CEOs. Everyone knows that regular exercise and weight training lead to physical strength. But how do we strengthen ourselves mentally for the truly tough times? And what should we do when we face these challenges? Or as psychotherapist Amy Morin asks, what should we avoid when we encounter adversity? Through her years counseling others and her own experiences navigating personal loss, Morin realized it is often the habits we cannot break that are holding us back from true success and happiness. Indulging in self-pity, agonizing over things beyond our control, obsessing over past events, resenting the achievements of others, or expecting immediate positive results holds us back. This list of things mentally strong people don't do resonated so much with readers that when it was picked up by Forbes.com it received ten million views. Now, for the first time, Morin expands upon the thirteen things from her viral post and shares her tried-and-true practices for increasing mental strength. Morin writes with searing honesty, incorporating anecdotes from her work as a college psychology instructor and psychotherapist as well as personal stories about how she bolstered her own mental strength when tragedy threatened to consume her. Increasing your mental strength can change your entire attitude. It takes practice and hard work, but with Morin's specific tips, exercises, and troubleshooting advice, it is possible to not only fortify your mental muscle but also drastically improve the quality of your life. |
