| different threshold psychology definition: 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. |
| different threshold psychology definition: 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. |
| different threshold psychology definition: 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. |
| different threshold psychology definition: 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. |
| different threshold psychology definition: Handbook for Teaching Introductory Psychology Michelle Rae Hebl, Charles L. Brewer, Ludy T. Benjamin, Jr., 2001-08-01 Like its predecessors, Volume III of the Handbook for Teaching Introductory Psychology provides introductory psychology instructors with teaching ideas and activities that can immediately be put into practice in the classroom. It contains an organized collection of articles from Teaching of Psychology (TOP), the official journal of the Society for the Teaching of Psychology, Division 2 of the American Psychological Association. Volume III contains 89 articles from TOP that have not been included in other volumes. Another distinction between this volume and its predecessors is its emphasis on testing and assessment. The book is divided into two sections. Section One, Issues and Approaches in Teaching Introductory Psychology, contains 52 articles on critical issues, such as: how to approach the course; understanding students' interests, perceptions, and motives; students' existing knowledge of psychology (including their misconceptions); a comparison of introductory textbooks and tips on how to evaluate them; test questions and student factors affecting exam performance; an overview of different forms of feedback; giving extra credit; and how to deal with academic dishonesty. Section Two consists of 37 articles that present demonstrations, class and laboratory projects, and other techniques to enhance teaching and learning in both the introductory, as well as advanced courses in the discipline. This section is organized so as to parallel the order of topics found in most introductory psychology textbooks. Intended for academicians who teach the introductory psychology course and/or oversee grad assistants who teach the course, all royalties of the book go directly to the Society for the Teaching of Psychology to promote its activities to further improve the teaching of psychology. |
| different threshold psychology definition: 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. |
| different threshold psychology definition: 13 Things Mentally Strong People Don't Do Amy Morin, 2014-12-23 Kick bad mental habits and toughen yourself up.—Inc. 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. |
| different threshold psychology definition: 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. |
| different threshold psychology definition: Dictionary of Psychology Mike Cardwell, 2014-01-27 Psychology as a subject is notorious for its often confusing use of language, particularly as many words that have one meaning in common everyday language have quite a different meaning when used as specialist terms in psychology. Dictionary of Psychology is an A-Z guide to key terms in the subject. Each entry begins with a clear, one-sentence definition and is followed by explanation and examples. Entries are developed in line with the relative importance of the topic covered. For many of the more central topic areas, further commentary is included to assist the reader in acquiring a critical understanding of the topic in question. Entries are carefully cross-referenced, and the format makes the Dictionary of Psychology very easy to use. |
| different threshold psychology definition: 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. |

| different threshold psychology definition: 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. |

| different threshold psychology definition: 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. |

| different threshold psychology definition: The Measurement of Sensation Donald Richard John Laming, 1997 The publication in 1957 of S.S. Stevens' famous paper, On the psychophysical law, ignited a controversy which has continued ever since relating to people's subjective judgements of physical reality. Why is it that the perception of sensation can diverge so sharply from the magnitude of thestimulus? How should sensation be measured? Donald Laming brings together a diversity of ideas and a wealth of experimental evidence, and provides a challenging new perspective on the question which has fragmented the research community for nearly 40 years. |
| different threshold psychology definition: A Practical Logic of Cognitive Systems Dov M. Gabbay, John Woods, 2005-05-02 The present work is a continuation of the authors' acclaimed multi-volume APractical Logic of Cognitive Systems. After having investigated the notion ofrelevance in their previous volume, Gabbay and Woods now turn to abduction. Inthis highly original approach, abduction is construed as ignorance-preservinginference, in which conjecture plays a pivotal role. Abduction is a response to acognitive target that cannot be hit on the basis of what the agent currently knows.The abducer selects a hypothesis which were it true would enable the reasoner to attain his target. He concludes from this fact that the hypothesis may be conjectured. In allowing conjecture to stand in for the knowledge he fails to have, the abducer reveals himself to be a satisficer, since an abductive solution is not a solution from knowledge. Key to the authors' analysis is the requirement that a conjectured proposition is not just what a reasoner might allow himself to assume, but a proposition he must defeasibly release as a premiss for further inferences in the domain of enquiry in which the original abduction problem has arisen.The coverage of the book is extensive, from the philosophy of science tocomputer science and AI, from diagnostics to the law, from historical explanation to linguistic interpretation. One of the volume's strongest contributions is its exploration of the abductive character of criminal trials, with special attention given to the standard of proof beyond a reasonable doubt.Underlying their analysis of abductive reasoning is the authors' conception ofpractical agency. In this approach, practical agency is dominantly a matter of thecomparative modesty of an agent's cognitive agendas, together with comparatively scant resources available for their advancement. Seen in these ways, abduction has a significantly practical character, precisely because it is a form of inference that satisfices rather than maximizes its response to the agent's cognitive target.The Reach of Abduction will be necessary reading for researchers, graduatestudents and senior undergraduates in logic, computer science, AI, belief dynamics, argumentation theory, cognitive psychology and neuroscience, linguistics, forensic science, legal reasoning and related areas.Key features:- Reach of Abduction is fully integrated with a background logic of cognitive systems.- The most extensive coverage compared to competitive works.- Demonstrates not only that abduction is a form of ignorance preservinginference but that it is a mode of inference that is wholly rational.- Demonstrates the satisficing rather than maximizing character ofabduction.- The development of formal models of abduction is considerably more extensive than one finds in existing literature. It is an especially impressive amalgam of sophisticatedconceptual analysis and extensive logical modelling.· Reach of Abduction is fully integrated with a background logic of cognitive systems.· The most extensive coverage compared to competitive works· Demonstrates not only that abduction is a form of ignorance preservinginference but that it is a mode of inference that is wholly rational.· Demonstrates the satisficing rather than maximizing character ofabduction.· The development of formal models of abduction is considerably more extensive than one finds in existing literature.

This groundbreaking text goes to the very heart of the therapeutic meeting between therapist and client. Focusing on the concept of ′relational depth′, the authors describe a form of encounter in which therapist and client experience profound feelings of contact and engagement with each other, and in which the client has an opportunity to explore whatever is experienced as most fundamental to her or his existence. The book has helped thousands of trainees and practitioners understand how to facilitate a relationally-deep encounter, identify the personal ‘blocks’ that may be encountered along the way, and consider new therapeutic concepts – such as ′holistic listening′ – that help them to meet their clients at this level. This classic text remains a source of fresh thinking and stimulating ideas about the therapeutic encounter which is relevant to trainees and practitioners of all orientations. |

Vance, 2013-09-03 A Laboratory Introduction to Psychology was written to acquaint the student with the concepts and methods of laboratory science as they apply to psychology. It is assumed that the laboratory course will follow or accompany a comprehensive course in introductory psychology which emphasizes scientific topics. The experiments have been related to journal articles and to sections of several popular textbooks so that students and instructors will have ready access to introductory material. This manual is limited to standard topics of experimental psychology, but includes some experiments that are relatively new. The topics discussed are grouped into in three main categories: Animal Behavior, Sensory Processes, and Human Behavior. Within each of these sections, the experiments are somewhat connected in shorter series. The Animal Behavior studies include one series consisting of conditioning, extinction, discrimination, and secondary reinforcement, and a second series on schedules of reinforcement and motivation. The experiments on Sensory Processes include some threshold measurements, and also a series of studies on perceived magnitude, adaptation level, and illusions. The experiments on Human Behavior include a series on learning and transfer, on short-term memory, and on two-person interactions. |

| different threshold psychology definition: Reinventing Structuralism Rodney B. Sangster, 2013-05-28 This monograph argues that the structuralist movement in linguistics was curtailed prematurely, before its contribution to cognitive science could be fully realized. Building upon Roman Jakobson's pioneering work on the nature of the linguistic sign, a new and detailed appreciation of the role of sign relations in the ultimate structuring of consciousness is presented, proving that the structural approach has as much to contribute today as any current cognitive theory. This study takes the view that the structure which linguistic signs themselves evince should be treated as an organic property of mind in its own right, as the device by which the ultimate differences in meaning in the human cognitive sphere are realized. Adherence to this principle assumes not only that the linguistic sign must be fundamentally monosemic, but also that the level of abstraction at which the relations between signs function must lie beyond the logical or rational level where polysemy is the rule. The study demonstrates that while the conceptual relations or categories uncovered at such a higher-order level of consciousness are of necessity highly abstract and hidden from normal awareness, they are nevertheless neither ineffable nor devoid of content. Rather, the categories identified and defined in this study are shown to have verifiable correlates at the supra-rational level where transpersonal rather than ego-oriented psychology operates, the level that Jung termed the collective unconscious. It is here that we find corresponding properties in reports from altered states of consciousness, in the structure of myths worldwide, as well as in studies of the image-making capacity of the human mind. Ultimately, when the structure of actual linguistic signs is treated as an ordered set of conceptual relations, one necessarily arrives at the conclusion that the sign relations of different languages are anything but Whorfian, but are all pointing to the same universal set of conceptual properties. This set of properties is then shown to be able to account for the relations between signs in all areas of linguistic structure, from the grammatical to the lexical and the syntactic. The monograph goes on to provide a detailed account of the process of making reference, of how speakers are able to contextualize the truly abstract conceptual relations inherent in the structure of signs in their language, to produce a potentially infinite variety of polysemous meanings in actual speech situations at whatever level of concreteness they choose; and how the feedback from such acts of communication determines the evolutionary trajectory of a system of signs conceived as a living organism, specifically as a neuronal structure inherent in the human brain operating as a fundamentally probabilistic or stochastic system. |

K., 2002-01-01 This revised and expanded edition is a sequel to the first edition which was warmly received by the student and teaching community for its indepth analysis and refreshing approach to the subject. Psychology of Individual differences Transfer of Learning or Training Emotional Development and Emotional Intelligence Learning Disabilities and Learning Disabled Children Beginning with an introduction to the nature and scope, and the various schools of psychology, the book dis-cusses the systems propounded by Freud, Adler, Jung and Piaget, taking into account their critical importance to the subject. It then focuses on the psychology of growth and development, psychology of individual differences, motivation, attention and personality, with an emphasis on the individual's attitude towards learning, and the factors influencing learning. The text also elaborates the nature and theories of learning and the aspects of memory such as remembering and forgetting. The cognitive aspect, i.e. intelligence, and vital topics like creativity and the psychology of thinking, reasoning and problem-solving have been accorded due promi-nence. A detailed discussion on exceptional children and learning disabled children together with the educational measures for overcoming such disabilities is also included. The text concludes with an important aspect of human behaviour, namely, adjustment. Interspersed with examples, illustrations and tables, this text is ideally suited for postgraduate students of education and psychology. It can also be profitably used by teachers, teacher-educators, guidance and counselling personnel, and administrators of educational institutions. |

| different threshold psychology definition: 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. |

| different threshold psychology definition: 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. |
