Memory in the Real World
100

This type of memory lasts less than 1 second and holds visual information.

Iconic memory

100

This type of rehearsal—repeating information over and over—is great for short-term memory but terrible for long-term memory.

Maintenance rehearsal

100

This type of retrieval is tested by multiple choice exams where you identify the correct answer among options.

Recognition

100

This theory of forgetting suggests the information never entered long-term memory to begin with.

Encoding failure

100

Memory works like a _______, reconstructing events using available evidence. Not like a video recorder.

A detective

200

This is the term for the brief holding place where sound is stored for about 4 seconds.

Echoic memory

200

This type of rehearsal involves connecting new information to what you already know.

Elaborative rehearsal

200

This type of retrieval requires you to reproduce information with minimal cues, like on essay exams.

Recall

200

This occurs when old information interferes with learning new information, like typing your old password.

Proactive interference

200

According to Glass and Kang's research, students who used devices during class scored this much lower.

Half a letter grade

300

George Miller found that short-term memory can hold 7 plus or minus 2 of these meaningful units.

Chunks

300

According to Craik and Lockhart, this type of processing—thinking about meaning—creates the strongest memories.

Semantic processing

300

This study approach spreads sessions over time with gaps, forcing retrieval when you return to material.

Spacing (or distributed practice)

300

This occurs when new information interferes with old information, like a new phone number making you forget your old one.

Retroactive interference

300

Each time you retrieve and reconstruct a memory, this happens to the memory.

It can change slightly (or be altered)

400

This is why short-term memory is also called "working memory."

It's where we do mental work like problem-solving and decision-making

400

This ancient memory technique, also called a memory palace, involves placing information along a familiar route.

Method of Loci

400

Students should study using this harder skill even though multiple choice exams test the easier skill of recognition.

Recall

400

The "tip of the tongue" phenomenon is best explained by this type of forgetting involving missing retrieval cues.

Cue-dependent forgetting

400

Jennifer Thompson was absolutely certain about her identification, but this type of evidence proved she was wrong.

DNA evidence

500

Echoic memory lasts longer than iconic memory for this reason related to how sound unfolds.

Sound unfolds over time and needs longer duration to be meaningful

500

Sleep helps memory by doing this to memories and neural connections.

Consolidating memories and strengthening neural connections

500

For an exam in one week, this study schedule is most effective according to the spacing effect.

30 minutes per day for 7 days

500

According to Craik and Lockhart's research, this matters more than how long you study.

How you process information (or depth of processing)

500

The Ronald Cotton case demonstrates that these two qualities are not the same thing when it comes to memory.

Certainty and accuracy (or confidence and correctness
