 کو دہرانا lặp lại 重复 echo Echo and Narcissus - Google Arts & Culture Echo and Narcissus Walker Art Gallery, Liverpool In the Roman myth, Echo fell in love with the beautiful Narcissus.

But Narcissus, on seeing his own reflection in a fountain, became infatuated with it and consequently despised Echo. She then pined away until only her voice remained. Waterhouse has marvellously represented the self-absorption of Narcissus as he sprawls on the ground looking downwards and totally oblivious of the very desirable Echo separated from him by the river. Her cramped pose demonstrates the frustration of unrequited love - a very common theme in Victorian art and a favourite theme for the artist. The landscape background has a sinister atmosphere appropriate to the subject and a decorative quality with strong, distinct shapes. Read more tag / style: Romanticism; Classicism; Pre-Raphaelite; mythological; Roman; Echo; Narcissus; John William Waterhouse ; reflection Physical Dimensions: w1892 x h1092 cm (Without frame) Artist biographical information: Waterhouse was a painter of poetical, imaginative subjects, often with a female figure in the role of an enchantress. Born in Rome in 1849, the artist was frequently to return to the city throughout his career and was heavily influenced by his experiences there.

Waterhouse's artistic skills were nurtured in his father's studio, before he went on to study at London’s Royal Academy Schools. He exhibited at the Royal Academy from 1874 to 1917, was elected an Associate in 1885 and a Royal Academician in 1895. Liverpool was also one of Waterhouse's main exhibition centres and his work was regularly exhibited in the Walker Art Gallery from 1879 until the year before his death. Often labelled a Pre-Raphaelite, Waterhouse should perhaps be regarded more as a Romantic Classicist, as his work is often more classical and Italian than medieval and gothic. He revived the literary themes that the Pre-Raphaelites favoured. His narrative ability was very strong and his works mainly illustrate scenes from his own interpretations of history, legend and poetry. Waterhouse was hugely popular in the 19th century and this continues to the present day. Additional artwork information: The painting was exhibited in London’s Royal Academy in 1903.

In a feature in The Art Journal that year, it was said that ‘Echo and Narcissus’ was ‘one of the best examples of imaginative art which can be found in the Academy.’To learn more about this painting, please follow this link: waterhouse .aspx To learn more about the Walker Art Gallery’s 20th-century paintings, of which this is one of the earliest examples, please follow this link: You Can Say That Again! Echolalia in Visually Impaired Children | WonderBaby.org You Can Say That Again! Echolalia in Visually Impaired Children By Mary McDonach The word Echolalia derives from the ancient Greek myth about a nymph named Echo who could only repeat the last words of other people. Unrequited love left her heartbroken and she pined away until only her voice remained. It's a cautionary tale about love and loss. You may think this is an old story with little relevance today, unless your blind child is constantly repeating everything you say or seems to get stuck repeating one word or phrase over and over. In that case, you may have your own little Echo on your hands. Does this conversation ring a few bells?

(Please excuse the grammar—it's a real life example from my real life!) Parent: "Which story would you like tonight?" Child: "What story am I wanting?" Parent: "That's right; Which story are you wanting?" Child: "What story am I wanting?" Parent: "Yes, what story are you wanting?" Child: "What story am I wanting?" Parent, now exasperated: "What story am you wanting. I mean... never mind. No stories tonight!" That really is a cautionary tale. Nowadays, it's thought that as many as 80% of blind and visually impaired children exhibit echolalia in their speech patterns. It's an ordinary part of language development (because it's an excellent way to practice and learn real language skills) and is often seen in normally sighted children, but their period of echolalic-type speech tends to be much shorter. Blind and visually impaired children, on the other hand, seem to find this behavior more useful, so for them it has a more extended life. How Could Echolalia be Useful? The uses of echolalia are many and varied. As mentioned above, it's actually a normal stage of language development for sighted children as well.

However, it's not uncommon for blind and visually impaired children to spend a bit longer in the echolalic stage since they find it can function in some ways as sight does for other children: Who's there? A sighted child simply has to look to see who is in a room; A blind child does not have this ability, but does have the same interest in finding out, even before he has the verbal skills to do this in an unobtrusive way. Repeatedly asking questions that may have no bearing on what he is trying to find out can seem odd but when we consider that his question will elicit some form of response from the others within a room, it is more readily understandable as functionally adapted behavior. Frequent repetition of the behavior can then be seen as keeping him informed about whom is there and who has left. Who's where Getting everyone to respond to him will also help your child know where others are in relation to him throughout a room. Notice how in the following example everyone at the table engages with Tommy in some way in response to his echolalia: Mum says, "Dinner time Tommy. Yum, yum." Tommy says, "Dinner time Tommy.

Yum, yum." Mum interprets correctly that this is Tommy's way of saying that he heard her. Tommy, now sitting at the dinner table with his siblings, says, "Dinner time Tommy. Yum, yum." His older brother says, "That's right Tommy." Tommy says, "Dinner time Tommy. Yum, yum". Older sister says, "You've already said that. Stop saying that." Tommy says, "Dinner time Tommy. Yum, yum." Baby sister says, "Yum, yum." Tommy says, "Yum, yum." Mum pulls her own hair out, strand by strand. Basic connections: A sighted child will make a primary contact with others using eye contact. Although this is not possible for the blind child, he still has the same fundamental need that the sighted child had for that initial contact with other people. Echolalia gives him the semblance of this contact—and since it's not necessary for the speech to do anything other than provide this connection, the child may not understand a need for it to be relevant speech, as echolalia does the job of mimicking frequent casual glances.

Conversations and social connections: The blind child's understanding of language (called responsive language) is, at this stage, greater than his ability to express language (called expressive language). He may have a desire to involve himself in the conversation of others but not have the ability to instigate or continue appropriate subjects. Echolalia can give the blind child the opportunity to seem to be involved in the conversation before his verbal abilities would allow it. This provides a feeling of inclusion in the social aspect of conversation which would otherwise have been fulfilled by eye contact and body language. Ironically, even though the blind child seeks social inclusion with his use of echolalia, he is actually increasingly seen by others as different. In addition to the echolalia, pronoun confusion is apparent in the speech of many blind children, and this only serves to multiply his apparent detachment from the group. Also, because his conversation can only ever be within the experience he already has and the clarity and usefulness of his experience is lessened because of his blindness, breaking away from this speech pattern can be very difficult, and what started as a transient developmental stage can become a rigidly performed habit. What can you do to minimize echolalia?

It is crucial to your sanity as a parent to remember that "This too will pass." Every child at some point exhibits idiosyncratic quirks of behavior. Showing your child that there can be easier, more practical ways to use language to achieve what he wants is the most effective use of a parent's time. Gentle, persistent guidance may be difficult when he is repeating for the 30th time something that was inane the 1st time, but it will work. This is not about preventing him from speaking and neither is it about a parent exerting dominance or control over a child's speech—on the contrary. This is about providing a path for your child to explore language, expand his abilities, and behave as an ordinary, social person and eventually a well-rounded, normal, socially-aware, and happy adult. And, as with raising any child, it's a huge and daunting task! Here are some tips to help you cope with your child's echolalia and encourage him to move on to more expressive forms of language. Read through this advice and work on what seems the best approach to you. Remember, all kids learn at their own pace and react in their own ways, so be patient and don't give up!

There is no quick fix. It is important for you to know and accept at the outset that giving your child an alternate to what works currently for him will take patience, commitment, and time. Language is his bridge to the world. His abilities with language will come directly from those around him, so make it work for both of you by providing him with a commentary on his world that grows with his understanding and abilities. The more expressive the language he is exposed to, the greater will be his ability with words; perhaps the most useful tool to give any child. So, for example, be sure to explain in very descriptive language what is going on around him, who is in the room and what they are doing, or what sounds he is hearing. A nice game to play is "I hear a..." because it builds on the child's desire to repeat a single phrase but also requires them to think and fill in the blank. So sit outside and listen and have your child tell you what he hears. Help him out by saying, "I hear a motorcycle, I hear an airplane, I hear the leaves rustling in the breeze, etc." Encourage him to listen and label his own sounds. Explain the unspoken language of sighted people.

Explain what is going on. In order to "fit in" in a visual and sighted world he needs an understanding of what people do and why they do it. Describe the non-verbal language of others, give detail about the smiles, the nods, the gestures that complete other people's speech and help him to emulate this where appropriate. It will bridge what might otherwise be perceived as a gap in his social behavior. Model the correct response to a question or situation. Sometimes a gentle nudge in the direction of appropriate responses or behavior is all he will need to act correctly this time, and positive feedback to this will ensure he will remember what he did right, so he can use a variation of the behavior the next time. Success breeds success. Here's an example: The kindergarten teacher says every morning: "How are you today Tommy?" Every morning Tommy replies: "How are you today Tommy" Standing behind Tommy, his mum whispers in his ear: "Tommy's fine and he had a big bowl of cereal for breakfast." This is the correct response if mum was answering the teacher, but she's offering it to Tommy. Now he has a choice, he may still say what he usually says; one morning soon, he may give the correct response.

Or... Teacher says: "How are you today Tommy?" Then she says: "That's a question Tommy. I'd love to know if you are feeling well or grumpy or sad or happy." Tommy now has the answers to her question and a better idea of the parameters to follow. In addition, even if he is echolalic, he is more likely to repeat her last word—"happy"—which can be interpreted as a positive and appropriate response to her question, so he's winning already! Simplify your speech. When your child is very young and just beginning to speak, it's a good idea to keep things simple so that when he does repeat what you've said he's actually correct. So, for example, you may say, "Bye bye, sweetheart," instead of, "Bye bye, Tommy," because when he repeats, "Bye bye, sweetheart," his language will actually sound correct. Also, since blind children tend to have such a hard time with pronouns, it's a good idea to just drop them altogether, at least until your child is four or five years old and ready to move on to pronouns.

You may feel a little silly saying things like, "Mummy is going to pick you up now," or, "Tommy sounds tired," but it will help him know who you are taking about without having to decipher all those difficult pronouns. Don't ask unnecessary questions. When you ask a question that you don't really expect to be answered, you're just placing more pressure on your child. Instead of saying, "Are you ready for a bath?" you could say, "Bath is ready!" or, "Tommy's bath is ready." Either way, you're giving your child a phrase that they can readily repeat and learn as the signal that they're about to take a bath. Plus, what if they did answer your question and said no? You'd still give them a bath anyway, so don't leave yourself open to debate! Play up your child's strengths. If your child is good at repeating words and phrases then harness that power to teach them to talk on their own! Let them copy your phrases while you slowly phase out your words and encourage them to fill in the blanks. This is a great way to allow your child to gain control and take ownership of their own language.

Here's an example: Mum rolls a ball to Tommy: "Tommy has the ball!" Tommy, holding the ball, says: "Tommy has the ball!" The next day, Mum rolls the ball to Tommy: "Tommy has the b---" Tommy, holding the ball, says: "Ball. Tommy has the ball!" The next day, Mum rolls the ball to Tommy: "Tommy has the ----" Tommy, holding the ball, says: "Ball. Tommy has the ball!" The next day, Mum rolls the ball to Tommy but doesn't say anything. Tommy, holding the ball, says: "Tommy has the ball!" At this point Tommy gets lots of hugs and kisses for saying something on his own! Don't be tempted to ignore his echolalic speech. Any speech is an attempt to communicate and deserves a response from you. Whatever the quality of the content, your child needs to know that his efforts are valued. Find a Speech and Language Therapist who motivates and inspires both you and you child. Being able to trust the advice of a professional will be an invaluable addition to helping your child.

This is a long term issue, no quick fixes, no magic wands and it's a bit like guerrilla warfare; you'll have to be ever vigilant, ever ready with the correct word or phrase (or sometimes just an understanding cuddle) to save the day. And remember, it's no fun for him either. Start today and help him help move himself toward freedom of expression. (And just think of all the great arguments you're going to have when he's older!!!)

Echo, in Greek mythology, mountain nymph. She assisted Zeus in one of his amorous adventures by distracting Hera with her chatter. For this Hera made her unable to speak except to repeat another's last words. She fell in love with Narcissus, but when he rejected her, she pined away until only her voice remained.

In another myth, she was loved by Pan, who, because he could not win her, caused shepherds to tear her asunder; Gaea buried her limbs, leaving only her voice. echo, reflection of a sound wave back to its source in sufficient strength and with a sufficient time lag to be separately distinguished. If a sound wave returns within 1-10 sec, the human ear is incapable of distinguishing it from the orginal one. Thus, since the velocity of sound is c.344 m (1,130 ft) per sec at a normal room temperature of about 20&degC; (68&degF;), a reflecting wall must be more than 16.2 m (56 1-2 ft) from the sound source at this temperature for an echo to be heard by a person at the source. In this case the sound requires 1-20 sec to reach the reflecting surface and the same time to return. Bats navigate by listening for the echo of their high-frequency cry. Sonar and depth sounders work by analyzing electronically the echo time lag of sound waves, generally between 10 and 50 kilohertz, produced by underwater transducers.

Radar sets broadcast radio waves, usually between 100 and 10,000 megahertz, pick up the portion reflected back by objects, and electronically determine the distance and direction of the objects. A sound echo that is reflected again and again from different surfaces, as by parallel walls in a tunnel, is called reverberation. When a surface reflects sound it partially absorbs and partially reflects the energy. As the process is repeated the sound becomes weaker and weaker and eventually ceases. Echo A sound wave which has been reflected or otherwise returned with sufficient magnitude and time delay to be perceived in some manner as a sound wave distinct from that directly transmitted. Multiple echo describes a succession of separately indistinguishable echos arising from a single source. When the reflected waves occur in rapid succession, the phenomenon is often termed a flutter echo. Echoes and flutter echoes are generally detrimental to the quality of the acoustics of rooms. They may be minimized through the proper selection of room dimensions, room shape, and distribution of sound-absorbing materials. Echoes have been put to a variety of uses in measurement problems.

For example, the distance between two points can be measured by timing the duration required for a direct sound originating at one location to strike an object at the other point and to return an echo to the location of the initial source. Ultrasonic echo techniques have achieved considerable success in nondestructive testing of materials. See Reflection of sound , Sound , Ultrasonics Echo a device used in composition and performance that consists in the repetition of a musical phrase, gradually decreasing in volume, by the same or different voices or instruments. The echo is used mainly in choral works, operas, orchestral music, and chamber music. Sometimes the device is the basis for entire musical works or sections of works, as in O. di Lasso’s madrigal “O là, o che bon eccho,” or the section entitled “Echo” in J. S. Bach’s Partita in B minor for harpsichord. This device has been frequently used in operatic scenes (Orfeo ed Euridice by Gluck and Ariadne auf Naxos by R.

Strauss), and in classical compositions {Echo, a composition for two-string trios by Haydn, Hoboken II, 39; Nocturne for Four Orchestras by Mozart, K. 286). One of the registers of the organ is also called an echo. Echo (from the name of the nymph Echo in Greek mythology), an acoustic, electromagnetic, or other wave reflected from some barrier and perceived by an observer. For example, an acoustic echo may be observed upon reflection of an acoustic pulse, such as a knock or a brief, abrupt shout, from surfaces with good reflecting properties. An echo is discernible to the ear if the transmitted and received pulses are separated by a time interval τ ≥ 50–60 msec. An echo becomes multiple if there are several reflecting surfaces (near a group of buildings or in the mountains), the sound from which reaches the observer at moments of time separated by intervals of τ ≥ 50–60 msec. A harmonic echo arises upon the scattering of sound with a broad frequency spectrum by barriers with dimensions that are small compared with the wavelengths λ of the components of the spectrum. In an enclosure, numerous separate echoes merge into continuous repercussions (see REVERBERATION ).

An echo may be a means of measuring the distance r from a signal source to the reflecting object: r = cτ/2, where τ is the time interval between the signal burst and return of the echo and c is the velocity of wave propagation in the medium. Various applications of echo signals are based on this principle. The operation of sonar is based on the acoustic echo, which is also used in navigation, where echo sounders are used to measure depth. Electromagnetic echo is used in radar; being reflected from the ionosphere, it permits shortwave radio communication over great distances, as well as determination of the properties of the ionosphere. The echo-wave principle is also beginning to be used in the optical band of electromagnetic waves generated by a quantum optical generator. Elastic waves propagating in the crust of the earth, reflecting from layers of various rocks, form a seismic echo that is used to locate mineral deposits. Echoes can be used to measure the depth of boreholes (echo ranging of wells) and the height of the liquid level in tanks (ultrasonic level gauges). Echo methods are extensively used in ultrasonic flaw detection.

For some animals, such as bats, dolphins, and whales, acoustic echo is a means of orientation and of locating prey. REFERENCES You Can Say that Again!

Basic Connections: A sighted child will make a primary connection with others by using eye contact. Although eye contact is not possible for the blind child, he/she has the same need as the sighted child for that initial connection with other people. Echolalia gives him or her the semblance of this contact. It is not necessary for the speech to do anything other than provide connection. The child may not understand a need for speech to be relevant, as echolalia does the job of mimicking frequent casual glances. Conversations and Social Connections: At this stage the blind child's understanding of language (called receptive language) is greater than his or her ability to express things verbally (called expressive language). Your child may want to get involved in the conversation of others, but may not have the ability to initiate or continue discussion of appropriate subjects.

Echolalia can give the blind child the opportunity to seem to be involved in the conversation before his/her verbal abilities allow it. This behavior provides the child with a feeling of inclusion in the social aspects of conversation that would otherwise be fulfilled through eye contact and body language. Ironically, though the blind child seeks social inclusion through the use of echolalia, he/she is increasingly seen by others as different. In addition to echolalia, pronoun confusion is apparent in the speech of many blind children. This confusion serves to multiply the child's apparent detachment from the group. Breaking away from these speech patterns can be very difficult, and what started as a transient developmental stage can become a rigidly performed habit. What Can You Do to Minimize Echolalia? It is crucial to your sanity as a parent that you remember that this too will pass. Every child at some point exhibits idiosyncratic quirks of behavior. Showing your child that there are easier, more practical ways to use language is the most effective way for you to spend your time. Gentle, persistent guidance may be difficult when your child is repeating for the thirtieth time something that was inane the first time around, but it will pay off in the end.

Your effort is not about preventing him or her from speaking, and neither is it about exerting your dominance or control. On the contrary, this is about providing a path for your child to explore language and expand his/her abilities. You are guiding your child to behave as an ordinary, social person and eventually a well-rounded, socially aware, and happy adult. Here are some tips to help you cope with your child's echolalia and encourage him/her to move on to more expressive forms of communication. Read through these suggestions and try the ones that seem the best suited to your situation. Remember that all kids learn at their own pace and react in their own ways, so be patient and don't give up! There is no quick fix. It is important for you to know and accept at the outset that giving your child an alternative to what currently works for him or her will take patience, commitment, and time. Build a Language Bridge. Language is your child's bridge to the world. His abilities with language will come directly from those around him. Make language work for both of you by providing him with a commentary on his world that grows with his understanding and abilities.

| View On Black In this photo there seems to be… | Flickr View On Black In this photo there seems to be a face, that of Narcissus (?) and if you look at the rock and its reflection sideways, there's the formation of two hearts... In Greek mythology, Narcissus, Narkissos or The Self-Admirer (Greek: Νάρκισσος), was a hero of the territory of Thespiae in Boeotia who was renowned for his beauty. Several versions of his myth have survived: Ovid's, from his Metamorphoses; Pausanias', from his Guide to Greece, and one found among the Oxyrhynchus papyri. Pausanias locates the spring of Narcissus at Donacon 'Reed-bed' in the territory of the Thespians. Pausanias finds it incredible that someone could not distinguish a reflection from a real person, and cites a less known variant in which Narcissus had a twin sister. Both dressed similarly and hunted together. Narcissus fell in love with her.

When she died, Narcissus pined after her and pretended that the reflection he saw in the water was his sister. Some Greek tales suggest that he was sexually attracted towards his sister, and when she was alive, he made love to her. As Pausanias also notes, yet another tale is that the Narcissus flower was created to entice Demeter's daughter Persephone away from her companions to enable Hades to abduct her. In the tale told by Ovid, Echo, a nymph, falls in love with a vain youth named Narcissus, who was the son of the blue Nymph Leirope of Thespia. The river god Cephisus had once encircled Leirope with the windings of his streams, and thus trapping her, had seduced the nymph. Concerned about the baby's welfare, Leirope went to consult the prophet Teiresias regarding her son's future. Teiresias told the nymph that Narcissus "would live to a ripe old age, as long as he never knew himself". One day when Narcissus was out hunting stags, Echo stealthily followed the handsome youth through the woods, longing to address him but unable to speak first.

When Narcissus finally heard footsteps and shouted "Who's there?", Echo answered "Who's there?" And so it went, until finally Echo showed herself and rushed to embrace the lovely youth. He pulled away from the nymph and vainly told her to leave him alone. Narcissus left Echo heartbroken and she spent the rest of her life in lonely glens, pining away for the love she never knew, until only her voice remained. Eventually he became thirsty and and went to drink from a stream, but he wouldn't touch the water for fear of damaging his reflection, so he eventually passed away, staring at his own reflection. The Narcissus flower grew from where he died. There is an older version than the one related by Ovid in his Metamorphoses, which is a moral tale in which the proud and unfeeling Narcissus is punished by the gods for having spurned all his male suitors (see pederasty in ancient Greece). It is thought to have been intended as a cautionary tale addressed to adolescent boys. Until recently, the only source for this version was a segment in Pausanias about 150 years after Ovid.

A very similar account was discovered among the Oxyrhynchus papyri in 2004, an account that predates Ovid's version by at least fifty years. In this story, Ameinias, a young man, loved Narcissus but was scorned. As a way of rebuffing Ameinias Narcissus gave him a sword, which Ameinias used to kill himself on Narcissus' doorstep; he prayed to Nemesis that Narcissus would one day know the pain of unrequited love. This curse was fulfilled when Narcissus became entranced by his own reflection in a pool and tried to seduce the beautiful boy, not realising it was himself. He only realised that it was his reflection after trying to kiss it. Completing the symmetry of the tale, out of sorrow Narcissus took his sword and killed himself; his body then turned into a flower. Done

Question: Who pined away until only her voice remained because of unrequited love?
Answer: Echo
