Information Processing Blog 2



A student, Bella is trying to learn and retrieve her multiplication facts. 

Input: In Bella’s class her teacher teaches the class there 2 times tables. (2x1=2, 2x2=4)

Sensory Memory: Bella takes in the different color of markers the teacher is using to write the multiplication facts on the board. She also notices who she is sitting by during the lesson and here’s a lawnmower outside. Most of these specific memories are soon lost.

Working Memory: Bella uses maintenance rehearsal and repeats the facts over and over again and uses flashcards. She also uses chunking by organizing the facts from 2x1 to 2x10 in numerical order and realizes that she can count by 2’s to help her remember the multiplication facts. Some of the facts might be forgotten due to encoding failure because the information never reached long term memory storage.

Long Term Memory:  Bella uses declarative knowledge to store her multiplication facts. Multiplication facts are known facts that are always going to be the same. These will be permanently in her mind once stored in long term memory. If she encodes the facts in two different ways (verbal and pictures) she will be able to store the memories easier. During her multiplication facts quiz Bella has to recall of the facts that she has learned. Almost all of the facts come easily to her because of recall.

  1. Anything Bella notices (consciously) is already in working memory! If she's not paying attention to the sounds outside, she's still processing the information (it's getting to her brain or into her mind but it's not significant enough to make it to conscious thought, unless someone yelled her name from outside). Rehearsal will keep information in conscious thought, but it will not move it to long term memory (cause learning)--that's one reason flashcards--according to this model--would not promote learning. This is important to understand.

    The categorization you describe is a method of encoding, because it adds meaning to the information (meaning she's already famiiliar with in long term memory--the number 2).

    What do you mean by she 'uses declarative knowledge'?
