Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is the information processing approach to memory?

    Model answer

    The information processing approach compares the mind to a computer. Information passes through the stages of input, processing and output.

  2. 2

    What is input in the information processing approach?

    Model answer

    Input is information from the environment entering the memory system through the senses.

  3. 3

    What happens at the processing stage of memory?

    Model answer

    Processing is the stage where incoming information is organised and changed into a form that can be stored.

  4. 4

    What is output in the information processing approach?

    Model answer

    Output is information retrieved from memory and used, such as an answer or an action.

  5. 5

    Define encoding.

    Model answer

    Encoding is converting information into a form that memory can store. Information can be encoded visually, acoustically or by meaning.

  6. 6

    Define storage in memory.

    Model answer

    Storage is holding information in the memory system over time.
