Memory as Information Processing (p.237)

INTRODUCTION

Cognitive psychologists liken the mind to a computer information processor.


KEY CONCEPTS EXPLAINED

...Like a computer, the mind:


...Introduction to the Three Box Model: Three Interacting Memory Systems

...Challenge to the Three Box Model computer analogy


...Parallel Distributed Processing (PDP)/ Connectionist Model

GLOSSARY

parallel distributed processing (PDP)






Sensory Memory: Fleeting Impressions (p.239)


INTRODUCTION

Sensory memory acts as a holding bin until we select the items for our further attention.


KEY CONCEPTS EXPLAINED


GLOSSARY

sensory memory

sensory register




Short-term Memory: Memory's Work Area (p.239)


INTRODUCTION

The "working memory" processes information to be stored in long term memory. It is relatively brief and limited in capacity.


KEY CONCEPTS EXPLAINED

..Brief


..Encoded Format


..
Transfers selected information into long term memory.

..
..Working Memory: The mental "scratchpad".



..The "leaky bucket" problem.


..Chunks: Combating the leaky bucket

GLOSSARY

short-term memory (STM)

chunk



Long-term Memory: Final Destination (p.241)


Organization in Long-term Memory (p.241)

INTRODUCTION

The vast storage of information in long-term memory needs to be organized and indexed.


KEY CONCEPTS EXPLAINED

..Semantic Categories


..Network Models of Organization



..
Other Ways to Organize Information




GLOSSARY

long-term memory (LTM)


The Contents of Long-term Memory (p.243)

INTRODUCTION

The contents of long-term memory can be placed into the categories of skills and abstract knowledge.


KEY CONCEPTS EXPLAINED

..Procedural Memories: Knowing "how to."


..Declarative Memories: Knowing "that."


GLOSSARY

procedural memories

declarative memories

semantic memories  

episodic memories
