PS102 Lecture Notes - Lecture 8: Sensory Memory, Mind Map, Memory Span
PS102 LECTURE 8
o Memories are stored as part of a large integrated web of information
o Represented in the brain as a pattern of activation across entire neural networks
Information Processing Theory (Figure 8-1, 8-2)
• • Memory is similar to a computer (Three stage model of memory- Know the duration
(30
seconds without rehearsal for working memory or it is lost)
• • We can’t preserve our memory 100%, interferences between coding and retrieval
meaning our
memories are not as similar to computers
Parallel Distributed Model (Figure 8-3)
• This web of memories is similar to how neurons form networks in our brain (Our mind map of
apples is differently perceived by each individual)
Encoding
• • The transformation of information from one form/code to another (neural code)
• • Code can be sound to pattern, letter sequence, image, and tactile cue
• • Paying attention to incoming information (Garbage in= Garbage out)
Storage
• • The retention of encoded information over time
• • Has to be a memory trace
• • Can last from fractions of a second (sensory memory) to several seconds (short-term
and
working memory) to indefinitely (long-term memory)
Retrieval
• • Recovery of stored information when it is needed
o Recall (Must remember things from scratch)
o Recognition (Easier- Multiple Choice will have cue words)
Document Summary
Ps102 lecture 8: memories are stored as part of a large integrated web of information, represented in the brain as a pattern of activation across entire neural networks. Parallel distributed model (figure 8-3: this web of memories is similar to how neurons form networks in our brain (our mind map of apples is differently perceived by each individual) Encoding: the transformation of information from one form/code to another (neural code, code can be sound to pattern, letter sequence, image, and tactile cue, paying attention to incoming information (garbage in= garbage out) Storage: the retention of encoded information over time, has to be a memory trace, can last from fractions of a second (sensory memory) to several seconds (short-term and working memory) to indefinitely (long-term memory) Types and stages of memory: atkinson- shriffen model (aka store model, information processing theory, sensory input sensory memory (forgetting) short-term memory (rehearsal to send to long-term memory or forgetting) long-term memory.
