Discuss the Role of Neural and Hormonal Mechanisms in Aggression Essay Support that serotonin leads to aggressive behaviour has been found, as human and animal research suggest that serotonin levels influence aggression and violent behaviour. There seems to be a negative correlation as low levels of serotonin, increase aggressive behaviour. Although we cannot determine a causal link as the cause of aggression cannot be attributed solely to serotonin. The link between dopamine and aggression is not as clear as with serotonin. Although there does seem to be a relationship between high levels of dopamine and aggression. Dopamine is produced in response to rewarding stimuli such as food, sex and recreational drugs. Research suggests that some individuals try to find aggressive encounters because of the rewarding sensations it brings, caused by increases in dopamine. Researchers have also suggested that people can become addicted to aggression, in the same way that they become addicted to food, gambling, etc. Ferrari et al. made a rat fight for 10 consecutive days. On the 11th day it was not allowed to fight. Researchers found that in anticipation of the fight the rat’s dopamine levels had raised and serotonin levels had decreased. This shows that experience had altered the rat’s brain chemistry, gearing it up for a fight. This supports the idea that both neurotransmitters are involved in aggressive behaviour and suggests a possible cognitive element in aggression i. e. the anticipation the rats experienced seemed to altar the levels of neurotransmitters in the brain. It is hard to extrapolate these results from animals to humans as it is unclear whether the influence is the same for both. Hormonal mechanisms such as testosterone and cortisol, are chemicals which regulate and control body functions. It is said that hormone levels affect a person’s behaviour. An example of a hormone which affects body functions is testosterone. This hormone is found in both men and women, but in larger quantities in men. Testosterone makes aggression more likely, but there is not a causal link. Nelson found a positive correlation between levels of testosterone and aggressive behaviour in male and female prisoners. However these levels were not measured during the aggressive act so we cannot be sure whether hormonal levels are a causal factor. Observational studies of children have shown that they tend to become more aggressive once they enter puberty and their testosterone levels rise. Pillay found that male and female athletes involved in aggressive sports have higher levels of testosterone than those involved in non-aggressive sports. Despite these findings we can question this using the basal and reciprocal model of testosterone. Did the male and females have high levels of testosterone and so were more competitive and dominant, therefore enjoying aggressive sports as stated by the basal model of testosterone. Or were the high levels of testosterone in those involved in aggressive sports exerted due to the aggressive sports, as stated by the reciprocal model of testosterone. Whether testosterone causes aggression has not been proved, although it does have an effect on aggressive behaviour. It also plays a big role in encouraging other behaviours i. e. dominance, impulsiveness and competition. These are all adaptive behaviours in human evolution and therefore very important for our survival as species. Despite this, this is a deterministic view of human behaviour. If aggression is completely controlled by neural and hormonal levels then it follows that individuals don’t exert any free will over their actions and that their behaviour is completely determined by their biochemistry. There are many individuals who have high testosterone levels, who may choose not to act aggressively even though they may be provoked. This demonstrates how a person can exert their free will and choose to override biological impulses. By only understanding aggressive behaviour from a biological approach, these explanations can be criticised for being reductionist. Simpson argues that testosterone is just one factor linked to aggression and that the effects of environmental stimuli such as heat and overcrowding have at times been found to correlate strongly. Likewise social psychological theories of aggression, e. g. social learning theory and deindividualisation have also received a lot of research support, for example the studies conducted by Bandura and Zimbardo.

The Narrator in The Tell-Tale Heart :: Tell-Tale Heart Essays

The Narrator in The Tell-Tale Heart Through the first person narrator, Edgar Allan Poe's "The Tell-Tale Heart" illustrates how man's imagination is capable of being so vivid that it profoundly affects people's lives. The manifestation of the narrator's imagination unconsciously plants seeds in his mind, and those seeds grow into an unmanageable situation for which there is no room for reason and which culminates in murder. The narrator takes care of an old man with whom the relationship is unclear, although the narrator's comment of "For his gold I had no desire" (Poe 34) lends itself to the fact that the old man may be a family member whose death would monetarily benefit the narrator. Moreover, the narrator also intimates a caring relationship when he says, "I loved the old man. He had never wronged me. He had never given me insult" (34). The narrator's obsession with the old man's eye culminates in his own undoing as he is engulfed with internal conflict and his own transformation from confidence to guilt . The fixation on the old man's vulture-like eye forces the narrator to concoct a plan to eliminate the old man. The narrator confesses the sole reason for killing the old man is his eye: "Whenever it fell upon me, my blood ran cold; and so by degrees - very gradually - I made up my mind to rid myself of the eye for ever" (34). The narrator begins his tale of betrayal by trying to convince the reader he is not insane, but the reader quickly surmises the narrator indeed is out of control. The fact that the old man's eye is the only motivation to murder proves the narrator is so mentally unstable that he must search for justification to kill. In his mind, he rationalizes murder with his own unreasonable fear of the eye. The narrator wrestles with conflicting feelings of responsibility to the old man and feelings of ridding his life of the man's "Evil Eye" (34). Although afflicted with overriding fear and derangement, the narrator still acts with quasi-allegiance toward the old man; however, his kindness may stem more from protecting himself from suspicion of watching the old man every night than from genuine compassion for the old man.

A composer of several popular works, he is best known as the author of the epicRamcharitmanas, a retelling of the Sanskrit Ramayana in the vernacular Awadhi. Tulsidas was acclaimed in his lifetime to be a reincarnation ofValmiki, the composer of the original Ramayana in Sanskrit.[4] He is also considered to be the composer of the Hanuman Chalisa, a popular devotional hymn dedicated to Hanuman, the divine devotee of Rama.[5] Tulsidas lived permanently and died in the city of Varanasi.[6] The Tulsi Ghat in Varnasi is named after him.[3] He founded the Sankatmochan Temple dedicated to Hanuman in Varanasi, believed to stand at the place where he had the sight of Hanuman.[7] Tulsidas started the Ramlila plays, a folk-theatre adaption of the Ramayana.[8] He has been acclaimed as one of the greatest poets in Hindi, Indian, and world literature.[9][10][11][12] The impact of Tulsidas and his works on the art, culture and society in India is widespread and is seen to date in vernacular language, Ramlila plays, Hindustani classical music, popular music, and television series.

Different sources give the date as the third day of the bright half, seventh day of the bright half, or the third day of the dark half.[77][78] ————————————————- Works Kamban Kambar (Kampan in casual address) was a medieval Tamil poet and the author of the Tamil Ramayanam Ramavatharam, popularly known as Kambaramayanam, the Tamil version of Ramayana. He was born in the 12th century in Tiruvaluntur in Tanjore district ————————————————- Life Kambar belonged to the Ochchan or Occhan caste, traditionally nadaswaram players in southern India.[3][4] But he was brought up in the household of a wealthy farmer in Vennai Nellur in south India. The Chola king having heard of this talented bard, summoned him to his court and honoured him with the title Kavi Chakravarthi or The Emperor of Poets. The Ramavataram or Kamba Ramayanam of Kamban is an epic of about 11,000 stanzas as opposed to Valmiki’s 24000 couplets. Kamba Ramayana is not a translation of the Sanskrit epic by Valmiki, but an original retelling of the story of the God Rama. The poetic work is well known for its similes. Many Tamil poets, statesmen, kings and common people have praised Kambar for his Kambaramayanam which has more than 10000 songs forming one of the greatest epics of Tamil.

He was a prolific composer and highly influential in the development of the South Indian classical music tradition. Tyagaraja composed thousands of devotional compositions, most in praise of Lord Rama — many of which remain popular today. Of special mention are five of his compositions called the Pancharatna Krithis (English: â€Å"five gems†), which are often sung in programs in his honor. Tyagaraja was born in 1767 in Tiruvarur, Tiruvarur district, in what is now called Tamil Nadu, to Kakarla Ramabrahmam and Sitamma in a Telugu Brahmin family of the Mulukanadu subsect He was named Tyagaraja after Lord Tyagaraja, the presiding deity of the temple at Tiruvarur. Tyagaraja began his musical training under Sri Sonthi Ramanayya, a music scholar, at an early age. He regarded music as a way to experience God’s love. His objective while practising music was purely devotional, as opposed to focusing on the technicalities of classical music. Tyagaraja, who was totally immersed in his devotion to Lord Rama and led the most spartan way of life without bothering in the least for the comforts of the world, The songs he composed were widespread in their popularity. due to the labour of love by these musicians and researchers, there is a definitive collection of Thyagaraja’s music. However out of 24,000 thousand songs said to have been composed, about 700 songs remain known. Tyagaraja Aradhana, the commemorative music festival is held every year at Thiruvaiyaru in the months of January to February in Tyagaraja’s honour. This is a week-long festival of music where various Carnatic musicians from all over the world converge at his resting place. SAROD The sarod is a stringed musical instrument, used mainly in Indian classical music. Along with the sitar, it is the most popular and prominent instrument in Hindustani (northern Indian, Bangladeshi and Pakistani) classical music. The sarod is known for a deep, weighty, introspective sound, in contrast with the sweet, overtone-rich texture of the sitar, with sympathetic strings that give it a resonant, reverberant quality. It is a fretless instrument able to produce the continuous slides between notes known as meend (glissandi), which is important to Indian music. The sarod is believed by some to have descended from the Afghan rubab, a similar instrument originating in Central Asia and Afghanistan. The nameSarod roughly translates to â€Å"beautiful sound† or â€Å"melody† in Persian . Design The design of the instrument depends on the school (gharana) of playing. There are three distinguishable types, discussed below. The conventional sarod is an 17 to 25-stringed lute-like instrument — four to five main strings used for playing the melody, one or two drone strings, twochikari strings and nine to eleven sympathetic strings. The design of this early model is generally credited to Niyamatullah Khan of the Lucknow Gharana as well as Ghulam Ali Khan of the Gwalior-Bangash Gharana. Among the contemporary sarod players, this basic design is kept intact by two streams of sarod playing Another type is that designed by Allauddin Khan and his brother Ayet Ali Khan. This instrument, referred to by David Trasoff (Trasoff, 2000) as the 1934 Maihar Prototype, is larger and longer than the conventional instrument, though the fingerboard is identical to the traditional sarod described above. This instrument has 25 strings in all. Sarod strings are made either of steel or phosphor bronze. Early sarod players used plain wire plectrums, which yield a soft, ringing tone. Playing The lack of frets and the tension of the strings make the sarod a very demanding instrument to play, as the strings must be pressed hard against the fingerboard. There are two approaches to stopping the strings of the sarod. One involves using the tip of one’s fingernails to stop the strings, and the other uses a combination of the nail and the fingertip to stop the strings against the fingerboard

Corporal Punishment Of Children. - 981 Words

Corporal Punishment of Children When I was in middle school at St. Mary’s Catholic School, in Ethiopia, I used to see our teachers using different techniques to punish my classmates. I remember an incident in middle school where a friend of mine was punished in a harmful way because he failed to answer a question. Although the use of corporal punishment in schools is intended to change the behavior of the student, teachers should not be allowed to use this method to punish their students as it is not effective for the child’s behavioral change, and it affects the student’s behavior psychologically and physically. To start with, allowing teachers to use the corporal punishment causes physical damage on the student and abuses the child right. It is obvious that most punishments somehow results in pain. When I was in middle school, our math teacher Ms. Helen used to order us to solve a question by writing on the blackboard to show the other students. One day my classmate, Daniel was asked to solve a problem on the board, but he didn’t write a complete answer. Ms. Helen was so angry with him that she put her pen between his pointing and middle fingers and twisted it so tight. We were so terrified because we had never seen someone being punished like that before. Daniel couldn’t move his fingers and was taken to the hospital to fix his broken fingers.
