Short Term Memory

Long Term Memory (LTM)

• Depth of Processing

• Breadth of Processing-elaborative encoding

• Distributed Practicing

• Intentional Learning

• Incidental Learning

Measuring Memory

Three measures typically used:

Recognition

Recall

Relearning

Forgetting• Failure to Encode

• Consolidation Failure

• Decay

• Interference

• Motivated Forgetting

• Retrieval Failure

Amnesia

• Retrograde amnesia– Infantile amnesia

• Anterograde amnesia

Tip of the Tongue

• The feeling of being on the verge of recalling something

• Often you can say what letter it starts with, or how many syllables it has

Reconstruction

Piecing memory together from a few highlights, then filling in details based on what we think should have happened (schema)

False Memories

• Implanting memories

• Distinguishing fact from fiction– Reality monitoring– Source amnesia

Repressed Memories

• Memories of early sexual abuse

Eye Witness Testimony

• Relies greatly on reconstructive memory

• Influential in trials

• Accuracy is variable

Expertise

• Experts remember more details

• Probably due to use of elaborative encoding

Hypnosis

• Increases rememberer's confidence & amount of inaccurate information

• Doesn't increase memory accuracy

Factors Affecting Retrieval

• Serial Position

• Cues

• Environmental Context

• State-Dependence

• Stress and Anxiety

Improving Memory• Organization

• Spaced Practice

• Mnemonic Devices

• Method of Loci

• Peg-Word Method

• Acronyms

• Overlearning

• Recall Practice

Improving Memory: Tricks and Tools

• Improving memory retrieval– Mentally reinstate environment in which

information was learned

– Focus

– Keep tying

– Think of characteristics of the information sought

– Use external cues
