Nyctophobia
Fear of the dark is a common fear or phobia among children and, to a varying degree, adults. A fear of the dark does not always concern darkness itself; it can also be a fear of possible or imagined dangers concealed by darkness. Some degree of fear of the dark is natural, especially as a phase of child development. Most observers report that fear of the dark seldom appears before the age of two years. When fear of the dark reaches a degree that is severe enough to be considered pathological, it is sometimes called scotophobia (from – "darkness"), or lygophobia (from – "twilight"). Some researchers, beginning with Sigmund Freud, consider the fear of the dark to be a manifestation of separation anxiety disorder. An alternate theory was posited in the 1960s, when scientists conducted experiments in a search for molecules responsible for memory. In one experiment, rats, normally nocturnal animals, were conditioned to fear the dark and a substance called "scotophobin" was s ...

List Of Phobias
The English suffixes -phobia, -phobic, -phobe (from Greek φόβος ''phobos'', "fear") occur in technical usage in psychiatry to construct words that describe irrational, abnormal, unwarranted, persistent, or disabling fear as a mental disorder (e.g. agoraphobia), in chemistry to describe chemical aversions (e.g. hydrophobic), in biology to describe organisms that dislike certain conditions (e.g. acidophobia), and in medicine to describe hypersensitivity to a stimulus, usually sensory (e.g. photophobia). In common usage, they also form words that describe dislike or hatred of a particular thing or subject (e.g. homophobia). The suffix is antonymic to -phil-. For more information on the psychiatric side, including how psychiatry groups phobias such as agoraphobia, social phobia, or simple phobia, see phobia. The following lists include words ending in ''-phobia'', and include fears that have acquired names. In some cases, the naming of phobias has become a word game, of not ...

Anti-Scottish Sentiment
Anti-Scottish sentiment is disdain, discrimination, or hatred for Scotland, the Scots or Scottish culture. It may also include the persecution or oppression of the Scottish people as an ethnic group, or nation. It can also be referred to as Scotophobia or Albaphobia. See antonym Anglophobia. Middle Ages Much of the negative literature of the Middle Ages drew heavily on the writings from Greek and Roman antiquity. The writings of Ptolemy in particular dominated concepts of Scotland till the Late Middle Ages and drew on stereotypes perpetuating fictitious, as well as satirical accounts of the Kingdom of the Scots. The English Church and the propaganda of royal writs from 1337 to 1453 encouraged a barbarous image of the kingdom as it allied with England's enemy, the Kingdom of France, during the Hundred Years' War. Medieval authors seldom visited Scotland but called on such accounts as "''common knowledge''", influencing the works of Boece's "''Scotorum Historiae''" (Paris 152 ...

Nausea
Nausea is a diffuse sensation of unease and discomfort, sometimes perceived as an urge to vomit. While not painful, it can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, abdomen, or back of the throat. Over 30 definitions of nausea were proposed in a 2011 book on the topic. Nausea is a non-specific symptom, which means that it has many possible causes. Some common causes of nausea are gastroenteritis and other gastrointestinal disorders, food poisoning, motion sickness, dizziness, migraine, fainting, low blood sugar, anxiety, and lack of sleep. Nausea is a side effect of many medications including chemotherapy, or morning sickness in early pregnancy. Nausea may also be caused by disgust and depression. Medications taken to prevent and treat nausea and vomiting are called antiemetics. The most commonly prescribed antiemetics in the US are promethazine, metoclopramide, and the newer ondansetron. The word nausea is from Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He recalls the many times he has walked alone, and recollections of the feeling of being followed while walking at night. Strictly, the song is about paranoid ideas (fear of being watched or harmed by other persons) rather than phobia (fear of objects and situations), even though the latter is referred to in the lyrics ("Have a phobia that someone's always there"); darkness seems ...

Fear Of Ghosts
The fear of ghosts in many human cultures is based on beliefs that some ghosts may be malevolent towards people and dangerous ''(within the range of all possible attitudes, including mischievous, benign, indifferent, etc.''). It is related to fear of the dark. The fear of ghosts is a very common fear. A persistent fear of ghosts is sometimes called phasmophobia, a type of specific phobia. It derives from Greek , , meaning "apparition" and , , meaning "fear". It is often brought about by experiences in early childhood and causes sufferers to experience panic attacks. Typical character The fear of ghosts is widespread even in post-industrial societies. Philosopher Peter van Inwagen wrote:"God and the Philosophers", edited by Thomas V. Morris (1996)p. 39/ref> "...I am perfectly aware that the fear of ghosts is contrary to science, reason and religion. If I were sentenced to spend a night alone in a graveyard, I should already know that twigs would snap and the wind moan and that t ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Etiology
Etiology (pronounced ; alternatively: aetiology or ætiology) is the study of causation or origination. The word is derived from the Greek (''aitiología'') "giving a reason for" (, ''aitía'', "cause"); and ('' -logía''). More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine (pertaining to causes of disease) and in philosophy, but also in physics, psychology, government, geography, spatial analysis, theology, and biology, in reference to the causes or origins of various phenomena. In the past, when many physical phenomena were not well understood or when histories were not recorded, myths often arose to provide etiologies. Thus, an etiological myth, or origin myth, is a myth that has arisen, been told over time or written to explain the origins of various social or natural phenomena. For example, Virgil's ''Aeneid'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LED Nightlight With Switch
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (UV), ...

Classical Conditioning
Classical conditioning (also known as Pavlovian or respondent conditioning) is a behavioral procedure in which a biologically potent stimulus (e.g. food) is paired with a previously neutral stimulus (e.g. a triangle). It also refers to the learning process that results from this pairing, through which the neutral stimulus comes to elicit a response (e.g. salivation) that is usually similar to the one elicited by the potent stimulus. Classical conditioning is distinct from operant conditioning (also called instrumental conditioning), through which the strength of a voluntary behavior is modified by reinforcement or punishment. However, classical conditioning can affect operant conditioning in various ways; notably, classically conditioned stimuli may serve to reinforce operant responses. Classical conditioning was first studied in detail by Ivan Pavlov, who conducted experiments with dogs and published his findings in 1897. During the Russian physiologist's study of digestion, Pav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethel Spowers Angst Vor Der Dunkelheit
Ethel (also '' æthel'') is an Old English word meaning "noble", today often used as a feminine given name. Etymology and historic usage The word means ''æthel'' "noble". It is frequently attested as the first element in Anglo-Saxon names, both masculine and feminine, e.g. Æthelhard, Æthelred, Æthelwulf; Æthelburg, Æthelflæd, Æthelthryth (Audrey). It corresponds to the ''Adel-'' and ''Edel-'' in continental names, such as Adolf (Æthelwulf), Albert (Adalbert), Adelheid (Adelaide), Edeltraut and Edelgard. Some of the feminine Anglo-Saxon names in Æthel- survived into the modern period (e.g. Etheldred Benett 1776–1845). ''Ethel'' was in origin used as a familiar form of such names, but it began to be used as a feminine given name in its own right beginning in the mid-19th century, gaining popularity due to characters so named in novels by W. M. Thackeray (''The Newcomes'' – 1855) and Charlotte Mary Yonge (''The Daisy Chain'' whose heroine Ethel's full name is E ...
