Object Permanence
Object permanence is the understanding that whether an object can be sensed has no effect on whether it continues to exist. This is a fundamental concept studied in the field of developmental psychology, the subfield of psychology that addresses the development of young children's social and mental capacities. There is not yet scientific consensus on when the understanding of object permanence emerges in human development. Jean Piaget, the Swiss psychologist who first studied object permanence in infants, argued that it is one of an infant's most important accomplishments, as, without this concept, objects would have no separate, permanent existence. In Piaget's theory of cognitive development, infants develop this understanding by the end of the " sensorimotor stage", which lasts from birth to about two years of age. Piaget thought that an infant's perception and understanding of the world depended on their motor development, which was required for the infant to link visual ...

Physical Object
In natural language and physical science, a physical object or material object (or simply an object or body) is a contiguous collection of matter, within a defined boundary (or surface), that exists in space and time. Usually contrasted with abstract objects and mental objects. Also in common usage, an object is not constrained to consist of the same collection of matter. Atoms or parts of an object may change over time. An object is usually meant to be defined by the simplest representation of the boundary consistent with the observations. However the laws of physics only apply directly to objects that consist of the same collection of matter. In physics, an object is an identifiable collection of matter, which may be constrained by an identifiable boundary, and may move as a unit by translation or rotation, in 3-dimensional space. Each object has a unique identity, independent of any other properties. Two objects may be identical, in all properties except position, ...

Carrion Crow
The carrion crow (''Corvus corone'') is a passerine bird of the family Corvidae, native to western Europe and the eastern Palearctic. Taxonomy and systematics The carrion crow was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', and it still bears its original name of ''Corvus corone''. The binomial name is derived from the Latin , "raven", and Greek , "crow". The hooded crow (''Corvus cornix''), formerly regarded as a subspecies, has been split off as a separate species, and there is some discussion whether the eastern carrion crow (''C. c. orientalis'') is distinct enough to warrant specific status; the two taxa are well separated, and it has been proposed they could have evolved independently in the wetter, maritime regions at the opposite ends of the Eurasian landmass.Madge, Steve & Burn, Hilary (1994): ''Crows and jays: a guide to the crows, jays and magpies of the world''.

Wax Argument
The wax argument or the sheet of wax example is a thought experiment that René Descartes created in the second of his ''Meditations on First Philosophy''. He devised it to analyze what properties are essential for bodies, show how uncertain our knowledge of the world is compared to our knowledge of our minds, and argue for rationalism.Newman, Lex"Descartes' Epistemology", The Stanford Encyclopedia of Philosophy (Fall 2010 Edition), Edward N. Zalta (ed.)/ref> The thought experiment Descartes first considers all the sensible properties of a sheet of wax such as its shape, texture, size, color, and smell. He then points out that all these properties change as the wax is moved closer to a fire. The only properties that necessarily remain are extension, changeability and movability: These properties are, however, not directly perceived through the senses or imagination (the wax can be extended and moved in more ways than can be imagined). Instead, to grasp the essence of the wax, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peekaboo
Peekaboo (also spelled peek-a-boo) is a form of play played with an infant. To play, one player hides their face, pops back into the view of the other, and says ''Peekaboo!'', sometimes followed by ''I see you!'' There are many variations: for example, where trees are involved, "Hiding behind that tree!" is sometimes added. Another variation involves saying "Where's the baby?" while the face is covered and "There's the baby!" when uncovering the face. Peekaboo uses a joke-like structure: surprise, balanced with expectation. Linguist Iris Nomikou has compared the game to a dialogue given the predictable back-and-forth pattern. Other researchers have called the game “protoconversation" – a way to teach an infant the timing and the structure of social exchanges. Object permanence Peekaboo is thought by developmental psychology, developmental psychologists to demonstrate an infant's inability to understand object permanence. Object permanence is an important stage of Infant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idealism
Idealism in philosophy, also known as philosophical realism or metaphysical idealism, is the set of metaphysics, metaphysical perspectives asserting that, most fundamentally, reality is equivalent to mind, Spirit (vital essence), spirit, or consciousness; that reality is entirely a mental construct; or that ideas are the highest type of reality or have the greatest claim to being considered "real".Goldschmidt et al. 2017, p. ix. Because there are different types of idealism, it is difficult to define the term uniformly. Indian philosophy contains some of the first defenses of idealism, such as in Vedanta and in Shaivism, Shaiva Pratyabhijna, Pratyabhijña thought. These systems of thought argue for an all-pervading consciousness as the true nature and ground of reality. Idealism is also found in some streams of Mahayana Buddhism, such as in the Yogachara, Yogācāra school, which argued for a "mind-only" (''cittamatra'') philosophy on an analysis of subjective experience.

Philosophical Realism
Philosophical realismusually not treated as a position of its own but as a stance towards other subject mattersis the view that a certain kind of thing (ranging widely from abstract objects like numbers to moral statements to the physical world itself) has ''mind-independent existence'', i.e. that it exists even in the absence of any mind perceiving it or that its existence is not just a mere appearance in the eye of the beholder. This includes a number of positions within epistemology and metaphysics which express that a given thing instead exists independently of knowledge, thought, or understanding. This can apply to items such as the physical world, the past and future, other minds, and the self, though may also apply less directly to things such as universals, mathematical truths, moral truths, and thought itself. However, realism may also include various positions which instead reject metaphysical treatments of reality altogether. Realism can also be a view about the ...

Solipsism
Solipsism ( ; ) is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind. Varieties There are varying degrees of solipsism that parallel the varying degrees of skepticism: Metaphysical Metaphysical solipsism is a variety of solipsism based on a philosophy of subjective idealism. Metaphysical solipsists maintain that the self is the only existing reality and that all other realities, including the external world and other persons, are representations of that self, having no independent existence. There are several versions of metaphysical solipsism, such as Caspar Hare's egocentric presentism (or perspectival realism), in which other people are conscious, but their experiences are simply not ''present''. Epistemological Epistemological solipsism is the variety of id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabeth Spelke
Elizabeth Shilin Spelke FBA (born May 28, 1949) is an American cognitive psychologist at the Department of Psychology of Harvard University and director of the Laboratory for Developmental Studies. Starting in the 1980s, she carried out experiments on infants and young children to test their cognitive faculties. She has suggested that human beings have a large array of innate mental abilities. In recent years, she has made important contributions to the debate on cognitive differences between men and women. She defends the position that there is no scientific evidence of any significant disparity in the intellectual faculties of males and females. Education and career Spelke did her undergraduate studies at Radcliffe College of Harvard University with the child psychologist Jerome Kagan. Her thesis studied attachment and emotional reactions in babies. She realized that she needed to have an idea of what babies really understood, and so began her lifelong interest in the cogni ...

Language Acquisition
Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language. In other words, it is how human beings gain the ability to be aware of language, to understand it, and to produce and use words and sentence (linguistics), sentences to communicate. Language acquisition involves structures, rules, and representation. The capacity to successfully use language requires human beings to acquire a range of tools, including phonology, morphology (linguistics), morphology, syntax, semantics, and an extensive vocabulary. Language can be vocalized as in speech, or manual as in sign language, sign. Human language capacity is language processing in the brain, represented in the brain. Even though human language capacity is finite, one can say and understand an infinite number of sentences, which is based on a syntactic principle called recursion. Evidence suggests that every individual has three recursive Mechanisms of mindfulness meditation, mech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hearing Impairment
Hearing loss is a partial or total inability to Hearing, hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to Language acquisition, acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Presbycusis, Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness. Hearing loss may be caused by a number of factors, including: genetics, ageing, Noise-induced hearing loss, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common condition that results in hearing loss is chronic ear infections. Certain infections during pregnancy, such as cytomegalovirus, syphilis and rubella, may also cause he ...
