Daniel Clement Dennett III (born March 28, 1942) is an American philosopher, writer, and cognitive scientist whose research centers on the philosophy of mind, philosophy of science, and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science.
The Rhine Research Center is an independent, non-profit parapsychology research center that takes a scientific approach to anomalous phenomena and exceptional human experience.
 According to the mission statement, the "Rhine's mission is to advance the science of parapsychology, to provide education and resources for the public, and to foster a community for individuals with personal and professional interest in PSI."
 It is the successor to the Parapsychology Laboratory at Duke University and is considered the oldest and most reliable source for information on the science of parapsychology in the United States.
Charles Darwin was one of the first scientists to write about the existence and nature of emotions in animals.
 His observational (and sometimes anecdotal) approach has developed into a more robust, hypothesis-driven, scientific approach.
 General hypotheses relating to correlates between humans and animals also support the claim that animals may feel emotions and that human emotions evolved from the same mechanisms.
 Several tests, such as cognitive bias tests and learned helplessness models, have been developed.
 Cognitive biases (feelings of optimism or pessimism) have been shown in a wide range of species including rats, dogs, cats, rhesus macaques, sheep, chicks, starlings, pigs and honeybees.
Jantje Visscher is an American painter, printmaker, photographer, sculptor, teacher and mentor.
 Visscher uses geometry and mathematics to explore the dynamics of perception and optical effects through the use of nontraditional mixed media.
 She is based in Minneapolis, MN and is currently active among the WARM (Women's Art Resources of MN) Mentor Program and the Traffic Zone Center for Visual Art.
 Visscher is best known for hard edge abstraction and minimalism within her scientific approach and exploration of perception and mathematics.
The Gambling Research Center (Universität Hohenheim) examines the various aspects of gaming and gambling through an interdisciplinary scientific approach.
 The goal of the Center is to systematically and scientifically examine the wide range of topics relating to gaming and gambling such as lotteries, sports betting, card games and gaming machines.
Heterophenomenology ("phenomenology "of another", not oneself") is a term coined by Daniel Dennett to describe an explicitly third-person, scientific approach to the study of consciousness and other mental phenomena.
 It consists of applying the scientific method with an anthropological bent, combining the subject's self-reports with all other available evidence to determine their mental state.
 The goal is to discover how the subject sees the world him- or herself, without taking the accuracy of the subject's view for granted.
Sonja Lyubomirsky is a professor in the Department of Psychology at the University of California, Riverside and author of the bestseller "The How of Happiness: A Scientific Approach to Getting the Life You Want", a book of strategies backed by scientific research that can be used to increase happiness.
Alastair Hannay (born 1932) is Professor emeritus at the University of Oslo.
 Educated in Edinburgh, where his early interest in philosophy was roused by John Macmurray, and London, where he studied under A. J. Ayer and Bernard Williams.
 In his published doctoral dissertation "Mental Images - A Defence" (1971) Hannay argues that visual images, like physical portraits, resemble visible objects.
 As a kind of sensation a mental image has material properties of its own which allow it to picture.
 He thus contradicts Gilbert Ryle and Daniel Dennett.
 Hannay has translated Søren Kierkegaard, and written an intellectual biography and a monograph about his philosophy.
 Under Hannay's direction (managing editor 1962-71, editor 1971-2002), "Inquiry" grew into a widely read philosophical journal.
 In "Human Consciousness" (1990), Hannay reviews contemporary theories of human consciousness while maintaining a characteristic conservatism.
 Hannay argues that consciousness and the first-person point of view cannot be analysed or displaced by scientific materialism, nor can they be explained functionally, a view close to that of Thomas Reid, William Hamilton, and Ferrier.
 Hannay's book "The Public" (2004) brings several Kierkegaardian insights to bear on contemporary political life and examines the roles of the 'public' as audience as well as political participant.
 Hannay is also a member of a team translating Kierkegaard's complete journals and notebooks.
Hard systems is a problem-solving approach in systems science.
 It is opposing soft systems.
 Although soft systems thinking treats all problems as ill-defined or not easily quantified, hard systems approaches (systems analysis (structured methods), operations research and so on) assume that the problems associated with such systems are well-defined, they have a single, optimum solution, a scientific approach to problem-solving will work well, and that technical factors will tend to predominate.
Neuroesthetics (or neuroaesthetics) is a relatively recent sub-discipline of empirical aesthetics.
 Empirical aesthetics takes a scientific approach to the study of aesthetic perceptions of art, music, or any object that can give rise to aesthetic judgments.
 Neuroesthetics received its formal definition in 2002 as the scientific study of the neural bases for the contemplation and creation of a work of art.
 Neuroesthetics uses neuroscience to explain and understand the aesthetic experiences at the neurological level.
 The topic attracts scholars from many disciplines including neuroscientists, art historians, artists, psychologists,
