Short Term Memory 12 Marker
Outline and evaluate research into the duration, capacity and encoding of information in the short term memory.
Short term memory is information that we are currently aware of and that we pay attention to, information from the short term memory comes from focusing on sensory memory and once focused on stored in the long term memory until it recalled.
Research suggests that the duration of short term memory is limited to on average of up to 2 minutes. Duration is the amount of time a memory lasts before it is no longer accessible. The researchers Peterson & Peterson were testing how 24 university students could recall 3 random syllables after counting back from a generated number in multiples of 3. The finding of this research was the larger amount of time between seeing the syllables and recalls them lead to a decrease in the amount of people that could recall the original 3 syllables. The conclusion that was made from this was that as time increases a lower amount of people can recall as the time elapses. Some of the strengths of this experiment were that they found out the correct things about their aims and it supported their hypothesis, as well as meeting their aim and hypothesis a strong conclusion and strong correlation. These are advantages because they are all key things to make a successful experiment and in order to be acknowledge for hard work strong analysis and good evidence has to be used in order to get noticed, there were however some disadvantages to their experiment as there are to all these were that because they have only use 24 participants it cannot be generalised and this also makes it a unfair test and is not representative, as well as only 24 students they were all in university which is a biased sample as well as a biased age because it also means it cannot be generalised except internally for their year. As well as duration there are other things that make up key parts of the short term memory with capacity now to follow.
