Limitations of Influencing factors on Memory

Time Need to pay to remember How to deal with abstract material? Learning vs. retention Creative ability Interference – more material Doesn’t help memory in general No help if fail to use technique Does not help understanding of material Need to practice mnemonics!

Influencing factors on Memory Influencing factors on Memory Retrieval cues Serial position

Basic memory task: Free Learn list of words – break – memory test % correct for each word Retrieval cues Serial position curve Primacy Long-Term Memory Cued-recall Recency Recognition Short-Term Memory How good is your memory for music lyrics? Two independent systems Rhyming technique of memory Organized/chunking

1 Primacy and Recency Influencing factors on Memory Portion of Serial Position Curve Elaboration and Meaning Memory instructions for study conditions Shallow: Count # of vowels in words (physical) Deep: Synonym for words (meaning) Memory Test: Performance is significantly better for “deep” condition Effect of elaboration Connection to existing knowledge Notice similarities and differences Provides cues Slow presentation = more 30s delay after list rehearsal = better LTM presentation = reduces STM Provides distinct memory
