Coding is the way information is changed so that it can be stored in memory. Information enters the brain via the senses (e.g. eyes and ears). It is then stored in various forms.

Duration is a measure of how long a memory lasts before it is no longer available. STM has a very limited duration whereas LTM has potentially unlimited duration.

Capacity. This is a measure of how much can be held in memory. It is measured in terms of bits of information such as the number of digits. STM has a very limited capacity whereas LTM has potentially unlimited capacity.

Long-Term memory is the permanent memory store. In LTM, coding is mainly semantic (by meaning), it has unlimited capacity and can store memories for up to a lifetime (duration). This includes memory for events that have happened in the past.

Short Term Memory (STM) is the limited capacity memory store. In STM, coding is mainly acoustic (Sounds), capacity is between 5 and 9 items on average and duration is about 18 seconds. Memories that have happened in the immediate past.

Human Memory can be broadly defined as the process by which we retain information about events that have happened in the past.

This is a new instrument song that I have composed and want to share. I also plan to share more also.

The Raven  The raven is a blackbird which reflects gothic literature. Gothic Literature is partly characterised by mystery and the supernatural and for some reason, the raven is symbolic of both of these. A raven is considered a cold dark bird who is demonic and appears at midnight. Ravens are also symbolic of death which is common in gothic literature. Firstly, the imagery of the raven links to the idea that Shakespeare has used some gothic imagery not just with the raven but throughout the play, this could create a sense of mystery and/or tension for the jacobean audience. The mystery element could be indicative of Macbeths plan to murder King Duncan and his other friends and how this will cause a mystery in Scotland of what happened to King Duncan and why Macbeth is a tyrant of a king. The divine right of kings said god appointed kings and kings were only answerable to god and so to kill the king would be to go against God and this creates mystery and tension. The supernatural part of this imagery refers to the witches and their prophecies as well as the other supernatural images throughout the tragedy, remember that jacobean audience feared witches and the supernatural and the audience would be angry with Macbeth for trusting the witches. This most strongly links in with the witches as they are in some way what started everything off, they presented Macbeth with the idea of killing king Duncan. The Raven is symbolic of death which hints at not only all the people Macbeth murders throughout the play but also Macbeth’s death at the end of the play. The raven is present before any of Macbeths Murders and so it could foreshadow punishment for going against the divine right of kings.

himself is hoarse Something or someone that is hoarse is sounding rough and harsh and is normally because of a cold or lots of shouting. This could paint the idea that either Lady Macbeth keeps going on about Murdering King Duncan but also that the raven is trying to warn the Macbeths. Firstly, the idea of Lady Macbeth being hoarse looks at the idea that she keeps going on to Macbeth about killing King Duncan because not only it will give Macbeth power but she will also gain some power from the death of King Duncan. Lady Macbeth keeps talking about killing Duncan as she is afraid that Macbeth is too much of a coward without any ambition and so without her push, he will never kill Duncan and so therefore never become king. Secondly, the raven may be hoarse because he is warning Macbeth of the consequences of killing king Duncan but because lady Macbeth keeps going on to Macbeth the raven also has to keep warning Macbeth. Finally, the adjective hoarse could also create the impression that Duncan is an old man who is loyal to his country and so, therefore, Macbeth would not only be killing the King but an old, innocent, honest king.
