long term memory - correct answer - Archive of information about past events and
knowledge learned
- Storage stretches from a few moments ago to as far back as one can remember
- More recent memories are more detailed
- Works closely with working memory
serial position curve - correct answer Graph depicting both primacy and recency
effects on people's ability to recall items on a list
- Distinction between short term and long term memories
primacy effect - correct answer memory for items presented at the start of a list
recalled better than items presented in the middle of a list
primacy effect research - correct answer Rundus: 1971
- Asked participants to repeat the words out loud during 5 second intervals between words
- Words presented earlier were rehearsed more and more likely remembered
recency effect - correct answer memory for items presented last in a list are recalled
between than items presented in the middle of a list
recency effect research - correct answer Glanzer and Cunitz, 1966
- Asked participants to recall words after counting backwards for 30 seconds after hearing the last word
- Prevented rehearsal and removed words from STM
- Eliminated recency effect
long term memory components - correct answer episodic, semantic, procedural
,episodic memory - correct answer - Mental time travel: mentally traveling back in
time to reconnect with events that happened in the past
- Tied to personal experience, remembering is reliving
- Self knowing
semantic memory - correct answer - Accessing knowledge about the world that isn't
necessarily tied to a personal experience
- General knowledge, facts
- Knowing
semantic coding in STM research - correct answer Wickens and coworkers: 1976
Fruits group:
- Presented with the names of three fruits on each trial
- After each presentation, counted backwards for 15 seconds
- Asked to recall the names
Professions group:
- Presented with the names of three professions on trials 1, 2, 3, and with the names of three fruits on
trial 4
- After each presentation, counted backwards for 15 seconds
Asked to recall the names
Fruits group:
- Showed reduced performance on trials 2, 3, and 4, caused by proactive interference - the decrease in
memory that occurs when previously learned information interferes with learning new information
Professions group:
- Showed reduced performance on trial 4 represents a release from proactive interference
, Semantic coding of words negatively impacted STM
semantic coding in LTM research - correct answer Sachs: 1967
- Many participants correctly identified sentence 1 as being identical and knew that sentence 2 was
changed
- Some participants identified sentences 3 and 4 as matching one in the passage even though the
wording was different
- They remembered the sentence's meaning, but not its exact wording
- Specific wording is forgotten but the general meaning can be remembered for a long time
- Meaning rather than specific wording tends to be coded in LTM
separation of episodic and semantic memories - correct answer KC
- Damaged hippocampus
- No episodic memory, cannot relive past events
- Semantic memory intact, can remember general information about the past
LP
- Brain damage due to encephalitis
- Issue with semantic, cannot remember general information about the past
episodic memory intact, can relive past events
Levine and coworkers (2004)
- Participants kept diaries on audiotape describing everyday personal events and facts from semantic
knowledge
- Participants listened to audiotaped descriptions while in an fMRI scanner
- Recordings of everyday events elicited detailed episodic autobiographical memories
- Recordings of facts reminded people of semantic memories
- fMRI scan demonstrates that retrieving episodic and semantic memories activate different areas of the
brain
