Memory Chapter Summary
6.1 What are the three processes of memory and the different model of how memory works? Memory can be defined as an active system that receives information from the senses, organizes and alters it as it stores it away, and then retrieves the information from storage. The three process are:
Models of Memory
In the levels-of-processing model of memory, information that gets more deeply processed is more likely to be remembered. In the parallel distributed processing model of memory, information is simultaneously stored across an interconnected neural network that stretches across the brain.

6.2 How does sensory memory work?
Iconic memory is the visual sensory memory, in which an afterimage or icon will be held in neural form for about ¼ to ½ second. Echoic memory is the auditory form of sensory memory and takes the form of an echo that lasts for up to 4 seconds. 6.3 What is STM, and how does it differ from working memory? STM is where information is held while it is conscious and being used. It holds about 7 plus or minus two chunks of information. Working memory is an active system responsible for processing the information in STM. STM is easily lost through decay or interference.
6.4 How is LTM different from other types of memory?
LTM is the system in which memories that are to be kept more or less permanently are stored and is unlimited in capacity and relatively permanent in duration. Information that is more deeply processed, or processed according to meaning, will be retained and retrieved in duration. 6.5 What are the various types of LTM, and how is information stored in LTM organized? Procedural memories are memories for skills, habits, and conditioned responses. Declarative memories are memories for general facts and personal experiences and included both semantic memories and episodic memories. Implicit memories are...
