Performance Load

Performance Load

Q1

Performance load is the theory that the harder something is to do the less likely it is that it will be accomplished. For example if I want to make a sandwich I need to get bread, ham, butter, lettuce, mustard, onion and tomato. These are food stuffs that are easily found in my fridge and bread bin. However it requires physical and mental effort and energy for me to find them.

Then I need to combine these things together in the correct method with the correct quantity of each ingredient. This requires mental and physical effort from mr.

Now it you compare the process of making a sandwich to say travelling to Mars you start to see the difference in performance load.

Making a sandwich has a low performance load which means that it is likely that the endeavour will succeed.

However the trip to Mars has a high performance load. There needs to be a large amount of capital, physical effort, mental effort and time which means there is a greater chance of the endeavour failing.

The following was found on http://www.chambers.com.au/glossary/chunk.htm:

Chunking is a principle that applies to the effective communication of information between human beings. It is particularly useful in the domain of written communication. It was first put forward in the 1950s by a Harvard psychologist named George A. Miller. He published a landmark journal article entitled “The Magical Number Seven, Plus or Minus Two“. Miller studied the short term memory. For example, how many numbers people could be reliably expected to remember a few minutes after having been told these numbers only once. The answer was: “The Magical Number Seven, Plus or Minus Two”. Millers concept goes beyond numbers. For example, most of us can remember about seven recently learned chunks of similarly classified data. Keep this in mind when you are presenting information to other people.

So chunking is a principle that says that human can only remember so much in formation.
