Human Memory

Topic: human memory -based on a lecture.

Neuropsychology is the study of the structure and function of the brain as it relates to specific psychological processes and behaviors. Human memory is a big study topic, as it is an important mental process by which information is encoded, stored, and retrieved. Memory can be divided into three major categories which are sensory memory, short-term memory, and long-term memory. (Wikipedia)
To begin with, “sensory memory corresponds approximately to the initial 200–500 milliseconds after an item is perceived.” Sensory memory is often divided into iconic memory (visual input), and echoic memory (sound input). It is not often discussed in terms of somatic sensations, but the immediate perception is considered sensory memory. Specifically, sensory memory refers to memory of sensory input for the first second or two; anything longer is either short-term memory or long-term memory. (Classification by duration, psychology wiki) (Samuraitum, 2007)
Short-term memory allows recall for a short period of time with a limited capacity. The duration of short-term memory is believed to be in the order of seconds to a maximum of a minute or two. The nature of the material to be recalled varies, which makes it very difficult to demonstrate the exact capacity of short-term memory, but there are theories that state that the capacity of short-term memory is typically of the order of four to five items. For example, the beginning of a sentence needs to be help in mind while the rest is read in order to understand it. (Short-term memory, human-memory.net)
 To add on, long-term memory can store much larger amounts of information for possibly unlimited duration and its capacity is immeasurably large. Long-term memory is typically divided up into two major categories: declarative memory and implicit memory. Memories that can be consciously recalled such as facts and knowledge are declarative memory, which can also be divided into categories. Implicit memory is considered non-declarative memory or unconscious memory which includes priming and non-associative learning. Examples of long-term memory are: how to ride a bicycle, or remembering an old friend’s face after a long time. (Classification by duration, psychology wiki) (Classification by duration, psychology wiki)
In conclusion, sensory memory, short-term memory, and long-term memory are the three major categories when dividing the brain functions. They can be affected positively by conscious actions by the brain such as chunking or repetition, or negatively by some memory disorders such as Alzheimer or amnesia.

Should Religion Influence Government Decisions?

Date written: February 23rd, 2013
Topic: Should Religion Influence Government Decisions?
-Opinions may vary.

Although religions have set standards for human lives, governments should not be influenced by religions when making laws and decisions; considering that our communities have a wide range of diverse beliefs and cultures, there is no place for discrimination nowadays, and excluding a group of people from a legislation is not acceptable in the modern world. Every decision the government makes affects every citizen’s life in that country because people have to obey the laws.
To begin with, people have the freedom of and from religions bearing in mind that they come from different places with different beliefs and values, and that the laws have to be fair to every citizen. Laws give the society as a whole a sense of order, while religions give individuals something personal to believe in and hold on to. Also, religious beliefs are out of sync with the new public opinion about many groups of people and different actions, like homosexuals and abortion, such groups and actions are most likely to be socially acceptable, but are not acceptable at all in most religions.
Furthermore, religions have caused lots of wars and conflicts in the past, such as the crusades between 1095 and 1291, which left England broke, and the holocaust during the Second World War, where over six million Jews were killed. At this time, governments are more civilized, and are aware of the human rights and freedoms, they would not like any riots or discrimination against any race or religious groups, so they would not make laws based on a specific religion that takes away anyone’s rights by discriminating them.
To add on, religions should not influence government decisions because if only one group were included in a legislation, even if it were a majority, all the minority groups would be excluded; which would cause discrimination, chaos, and possibly a civil war. For instance, over three-thousand people died due the conflict between the Catholics and the Protestants in Ireland when England began to establish themselves as the ruling class in Ireland (Catholic) with protestant laws, moreover, Saddam Hussein ruled Iraq based on Sunni beliefs, so the Shi’ite were discriminated, which created a civil war.

As shown by history all in all, impeding the freedom of choice, bad experiences in the past such as genocides and religious holy conflicts, and discrimination among citizens are three main reasons religions should not influence government decisions. Religion is a belief, and government is a law made to keep things in order and protect the citizens.

Louis Armstrong - Influence on jazz

Date written: October 22nd, 2012
Topic: Louis Armstrong
Sources included

Louis Armstrong, also known as Satchmo or Pops, brought Jazz out of New Orleans and spread it around the world. He invented scat singing, which is using his voice as an instrument (vocalizing using sounds and syllables instead of lyrics). He was said to have used his instrument like a voice and his voice like an instrument. Armstrong was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. With his recognizable deep and distinctive rough voice, Armstrong was also an influential singer, demonstrating great skill as an improviser, bending the lyrics and melody of a song for expressive purposes. He was the top performer at a time when there wasn't internet or TV.
Coming to reputation in the 1920s as an "inventive" cornet and trumpet player, his work shows him playing at the outer limits of his abilities. Armstrong was a colourful character. He had a habit of telling tales, in his own biography he told tales about his early childhood, and his additions of his history often lack consistency. By the mid-1930s, Armstrong achieved a smooth assurance, knowing exactly what he could do and carrying out his ideas to perfection. He was the first soloist and the first African American to host a nationally broadcasted radio show in the 1930s.
In his early years, Armstrong was best known for his talent with the cornet and trumpet. The inventions he made on his records of New Orleans jazz standards and popular songs of the day are incomparable by later jazz performers. The older generation of New Orleans jazz musicians often referred to their inventions as "variating the melody." Armstrong's improvisations were daring and sophisticated for the time, while often subtle and melodic. In 1969, Armstrong also had a role in the film version of “Hello, Dolly!” As the bandleader, Louis sang the title song with actress Barbra Streisand. His solo recording of "Hello, Dolly!" is one of his most recognizable performances. This number one single knocked the Beatles off the top of the charts. In 1968 he recorded another hit called “What a Wonderful World.”
 He often re-composed pop-tunes he played, making them more interesting. Armstrong's playing is filled with happy, inspired original melodies. The genius of these passages is matched by Armstrong's playing technique, enhanced by constant practice, which extended the range, tone and capabilities of the trumpet. In these records, Armstrong almost created the role of the jazz soloist by himself, taking what was basically a collective folk music and turning it into an art form with marvellous possibilities for individual expression and emotion. He was one of the first artists to use recordings of his performances to improve his own skills. Armstrong was a keen audiophile. He enjoyed listening to his own recordings, and comparing his performances musically. At his home, he had the latest audio equipment and would sometimes rehearse and record along with his older recordings or the radio.
Armstrong had a leading personality of the day, who was so beloved by America, that he was able to live privately, a life of access and privilege according to few other African Americans. He tried to remain politically neutral, which gave him a large part of that access, but often alienated him from members of the black community who looked to him to use his status with white America to become more of an outspoken figure during the Civil Rights Era.
In 1972, Louis Armstrong was awarded the Grammy Lifetime Achievement Award by the Academy of Recording Arts and Sciences. The vote of the Recording Academy’s National Trustees presents the Special Merit Award, to creative performers who contributed by outstanding artistic significance to the field of recording.

Round Midnight - A Story About Jazz

Date written: December 7th, 2012
Topic: Development of Jazz - Round Midnight
This essay includes information about Lester Young, Bud Powell, Dexter Gordon


Music is an art of sound that expresses ideas and emotions in significant forms through the elements of rhythm, melody, and harmony. In the early 20th century, Jazz originated in black communities in the United States. By time, jazz has seen many changes and developments by many creative, talented musicians. Throughout the 1930s-1050s, major changes in jazz have been made, as the swing, bebop, and cool jazz eras were taking place. Some of the main influential jazz musicians who played major roles in the development of jazz are Lester Young, Bud Powell, and Dexter Gordon who played the role of Dale Turner in the movie Round Midnight.
To begin with, Lester Young was an American jazz musician who played the saxophone, clarinet, trumpet, violin, and drums. Young grew up in a musical family and he was inspired mainly by his father and brother. His father was a multi-talented musician, his brother was a drummer, and many of his relatives played music professionally. His dad organized them as a family band that played in carnivals and theatres. At the age of 18, his father proposed taking the band on a tour to the South, but he refused to go as he claimed that it was a place of racism and humiliation. Since then, he was an independent jazz musician. At that time, Coleman Hawkins was the king of the instrument, and most tenor saxophonists were imitating his style. As a saxophonist, Young brought a cool modernism and a new rhythmic flexibility to jazz, his playing was almost the complete opposite; his sound was soft and mellow in the lower registers, while his higher notes were clear and delicate, and his melodic lines were slow, and never in a hurry. In the 1930s, he became a member of The Count Basie Orchestra, where he rose to prominence and was the master of the clarinet. Young’s style when playing the clarinet influenced many other jazz musicians because his style was very unique and truly remarkable. He played with a cool tone and used sophisticated harmonies; his style satisfied both dancers and listeners. Also, Young invented and popularized the hipster character which was associated to music, as he was famous for his hip and quiet style.
Throughout the 1940s, Young performed with Count Basie’s Orchestra from time to time. “He claimed that he did not want to be a “repeater pencil”, which describes the act of repeating one’s own past ideas, but his playing showed reliance on a small number of clichéd phrases and reduced creativity and originality.” He produced some of the old, smooth-toned flow of the 1930s. In 1994, Lester was sent to the military, but his playing style was significantly different after he was sent back home. He began alcohol abuse from around 1951, because there was a declining command on the swinging music that he used to play, as the bebop era began. As a result, his level of playing declined rapidly. Although Young had many physical and mental issues, he still continued to play his instrument and recorded many of his “new” songs in the studio. In January 1959, Young travelled to Paris to continue his career as a jazz musician, but in March, his alcohol abuse put him through dangerous medical conditions, which made him fly back home.
Bud Powell was also a very influential jazz musician. As a child, he was influenced by his father, who was a pianist, and he was taught how to play the piano by a teacher whom his father hired. Powell showed his interest in jazz as he grew older, and his playing was heard all around the neighborhood. He had a significant impact on the development of bebop. His style became the leading approach for other pianists, as he reduced left hand functions to playing brief, shifted chords supporting long melody lines by the right hand. In 1945, Powell developed severe head injuries due to the police beating him on the head after a racially motivated attack, which interrupted his career several times for the rest of his life. In 1947, Powell got the chance to demonstrate his mature style when he was chosen to be Charlie Parker’s pianist along with three well-known jazz musicians. He acquired a brief solo spot in one of their performances, where his jocular chord filled while the horn players paused to breathe. In the late 1940s Powell developed alcohol abuse issues; even one drink had an overpowering impact on his character, making him aggressive and pessimistic.
In the late 1950s, he moved to Paris, in the company of a woman called Altevia "Buttercup" Edwards. In Paris, Powell worked in a trio with two other professional jazz musicians. He continued to perform and record despite the fact that Buttercup discouraged him from playing, as she did not have his best interests in mind, and kept control of his finances and overdosed him with medication. His technique formed the basic small ensembles that have dominated jazz since the bebop era. In his later years, some of his recordings and performances sounded quiet sad, while others would be scarily intense. However, he had a major role in the development of jazz and he will remain one of the most outstanding pianists ever. Nonetheless, many later pianists copied his daring attacks, looking to attain that rarefied status, of the fearless improviser.
Moreover, Dexter Gordon was an American jazz tenor saxophonist, one of the most influential saxophonists in modern jazz, and an Academy Award-nominated actor. Gordon started playing the clarinet since he was 13 and the saxophone at 15. One of his major influences was Lester Young. He was one of the primary innovators of bebop jazz and a lasting favorite of audiences and music critics. Crossing 50 years in recorded jazz history, Gordon’s studio and live performance careers were both extensive and complex. He is widely remembered for his wonderful charisma, his sense of style and sophistication, and his broad legendary sound on the saxophone, in addition to his innovative contributions in the world of Jazz. His styles included his clear, strong, metallic tones, their tendencies to bend up to high notes, and their abilities to single-tongue and still swing. One of Gordon's habits was to rehearse the lyrics of each ballad before playing it. Gordon spent 15 years in Europe, mostly in Paris and Copenhagen, where he played regularly with fellow expatriate jazzmen such as Bud Powell, and others. During the 1960s, Gordon experienced less racism and greater respect for jazz musicians in Europe.
            In 1986, Gordon starred in the movie Round Midnight as 'Dale Turner', an expatriate jazz musician much like him; although Lester Young and Bud Powell were its main inspirations the role might even be a lightly, indirect biography of him. In 'Round Midnight, real-life jazz legend Dexter Gordon brilliantly portrays the fictional tenor sax player Dale Turner, a musician slowly losing the battle with alcoholism, estranged from his family, and hanging on by a thread in the 1950's New York jazz world. Dale gets an offer to play in Paris, where, like many other black American musicians at the time, he enjoys a respect for his humanity that is not based upon the color of his skin. A Parisian man who is obsessed with Turner's music befriends him and attempts to save Turner from himself. Although for Dale the damage is already done, his poignant relationship with the man and his young daughter re-kindles his spirit and his music as the end draws near.
            Furthermore, the fictional character Dale Turner represents Lester Young’s original style and sophisticated tones when playing the saxophone. It also shows how listeners and dancers were pleased and entertained by his performances. To add on, the flashbacks about his military experience, the experience in Paris and the return to New York just before his death also show parallelisms to Young’s life. Additionally, Gordon played with Powell in the early 1960s, which helped him revise and rewrite the script. Dale Turner’s character also portrays Powell’s tortured and mysterious character, his experience with Buttercup, and his alcohol abuse issues. Dexter’s dynamic character allowed him to perfect the role of Dale Turner as a professional saxophonist, his experience with Powell helped him play the role, and his own experiences made him genuine about describing circumstances in Paris.


            To sum up, jazz have gone through a lot of changes and developments. Although Young, Powell, and Gordon have been through a lot of difficulties, they continued influencing other musicians because they were determined to make a difference in the jazz world. The fictional character, Dale Turner, in the movie Round Midnight portrays the circumstances that Lester Young and Bud Powell lived through, as they were Gordon’s influences.

Bullying

Date written: May 3rd, 2013
Topic: Bullying
Citations included.


Social networks are becoming more popular among kids nowadays. Some of them are using them for the wrong purposes though; as they are hurting other people’s feelings. Putting others down and pointing out their faults makes these kids feel somehow better about themselves. Bullying is anything that hurts another person’s feelings, makes them feel uncomfortable, or offends them. It could be verbal or physical. It is one of the most common causes of depression in our society. Victims of bullying tend to have lower self-esteem and could become aggressive in some cases. Bullying has changed many people’s lives, and people need to be more understanding to what others are going through.
To begin with, bullying scars its victims for life and these scars never heal or fade away. They have to live with this experience for the rest of their lives remembering every word that has been said to them and everything that has been done to them. Bullying takes away people’s identities, they feel inferior to people around them, weak, and insecure. It takes away their right of safety and security and gives them bad memories. Mark Dombeck, PH.D. wrote an article explaining the long-term effects of bullying, the feelings of its victims, and shared the stories of some people including his own.[1] To add on, bullying is the most common reason of depression amongst adolescents in our society. Depression causes suicidal thoughts and lots of suicide attempts. According to the Canadian Institutes of Health Research’s statistics, 47 percent of Canadian children are victims of bullying. [2] Also, there has been a few suicide cases, and 78 percent of the children who committed suicide were bullied at school and using social networks. [3]
Furthermore, people cannot really understand how it feels like to be a victim unless they were victims themselves. Most schools hold anti-bullying campaigns and get student volunteers to raise awareness about the effects of bullying between each other. Raising awareness is the least they could do. It is not that effective anymore nowadays though. In addition, there should be stricter rules about bullying and more effective punishment methods for bullies. That would show the victims that there is always someone there for them to protect them and keep bullies away from them, punishments would make bullies stop at some point. Even if people do not understand how it feels like to be a victim, they could at least appreciate what others are going through by not making it worse and help them stand up for themselves. Also, therapy is a great relief for victims of bullying or any other reason for depression. In the book The Worst Thing She Ever Did, Sophie is going through a trauma after her sister’s death. She decided to go to therapy and feels so much better after. “I realized it’s okay that it’s going to take me a long time to recover after what’s happened. It’s normal. “ [Kuipers]
“If you have nothing nice to say, don’t say anything at all.” That is one thing everyone should know and carry out in their lives. Most bullies get bullied at home, or got bullied at some point in their lives; being mean to people makes them feel more powerful over vulnerable persons. I strongly believe that people should have more understanding of the long-term effects of bullying and more appreciation to the strength that the victims have to deal with it every single day.
