Chapter 6- Long-Term Memory

Three goals of the chapter

Division: distinguish the types of memory

Interaction: how the different types of memory interact with each other

Results of behavior studies

How do LTM and WM work together?

WM holds new information and takes memory from LTM to understand it

Capacity and Duration of LTM

Capacity is unlimited

Duration is from 30 seconds to a lifetime

What does the Serial Position Curve look like?

in the beginning it dips down, but slowly goes back up towards the end

Primacy Effect

Words are remembered more at the beginning because of rehearsal

LTM

Recency Effect

Words are remembered at the end of the list since they are still in the STM

KC study

damages to hippocampus left no episodic memory —> inability to recall past memories

semantic memory intact —>ability to recall the fact that events happened

HM study

removed hippocampus led to inability to transfer memories from STM to LTM

Anterograde Amnesia

KF study

Parietal lobe damage left a poor STM but working LTM

no recency effect

LP Study

Temporal lobe damage impacted semantic memory but impaired episodic memory

Brain Imaging contribution to semantic and episodic memory

showed that each takes place in different brain regions

Autobiographical memory

combination of episodic and semantic

Ex: Weddings, graduation

Personal Semantic Memories

semantic memories with personal significance

Ex: phone numbers of others
