Q1)

  • PERFORMANCE LOAD: Refers to the amount of Pysical and mental activity required to obtain an end result. It is also made up of two other componants ‘congnitive load and kinematic load.  In order to maintain a lower error rate we need to make sure that the ‘performance load’ is lower.  In saying this I can imagine though that the amount of stress that one person can handle to another can be greater or less, and it depends on the person.
  • COGNATIVE LOAD: Is based on the amount of mental activity it takes to reach an end result.  
  • KINEMATIC LOAD: Incorporates the above mentioned in realtion to mental and physical activity that is needed to obtain the end result along with the amount of energy and movements needed to complet the end result.

Q2)

  • CHUNKING: We live in a culture that is full of information technology every day, in order to break some of this information down to be able to function effectively we can apply a technique called “chunking”, which simply means to group information so it can be easily understood.
  • For example the only difference between why we remember information is based on how it was presented.  When things are in order and organised they are much easier to process. Some examples of chunking and it’s positive effects are: credit card numbers and phone numbers, they are generaly grouped so they are easier to process.

Q3)

  • Psychology is effective in viual design simply because we can learn about our audiences needs more and then effectively incorporate that knowledge into the design of the product or message.  

 

  • I can help us to be more culturaly sensitive and learn how different colours effect peoples moods and emotions, after all when we purchase goods we tend to have and buy some emotional connection with it and or it defines a type of character and or status about ourselves.
