Study Notes

Long-Term Memory (LTM) vs Short-Term Memory (STM)

LTM stores information for long periods, while STM stores information for short periods.

Serial Position Curve

The Primacy Effect refers to better memory for the words at the beginning of a list.

Semantic Memory

Semantic memory stores general knowledge and facts.

Case of Patient KF

Patient KF, with parietal lobe damage, had severely impaired STM, but his LTM remained intact.

Episodic Memory

Episodic memory involves reliving past experiences.

Wickens et al. (1976)

Participants recalled words across multiple trials, demonstrating proactive interference (previous learning hindering new learning).

Expert-Induced Amnesia

Experts may be unable to describe how they perform certain tasks, a phenomenon called expert-induced amnesia.

Levels of Processing Theory (Craik & Lockhart, 1972)

Deeper levels of processing lead to better memory retention.

Procedural Memory

Knowing how to play a musical instrument is an example of procedural memory.

Grant et al. (1998)

Words learned in a noisy environment were better recalled in a noisy environment, demonstrating the influence of learning context on retrieval.

Glanzer and Cunitz (1966)

The recency effect (better memory for the last few items) can be eliminated by asking participants to perform a task before recall.

Proactive Interference

Learning a new phone number and forgetting the old one exemplifies proactive interference (old learning interfering with new learning).

Tulving (1985)

Episodic memory involves "self-knowing" and personal experiences, while semantic memory involves general knowledge.

Double Dissociation between STM and LTM

The Double Dissociation between STM and LTM is supported by the cases of HM (impaired LTM, intact STM) and KF (impaired STM, intact LTM).

Sachs (1967)

Participants recalled the meaning but not the exact wording of sentences, demonstrating that semantic memory is used for sentence recall.

Ranganath & D'Esposito (2001)

The hippocampus is responsible for maintaining novel information during short delays.

Semanticization

Over time, episodic memories become more like semantic memories, a process called semanticization.

Long-term Memory and Retrieval

Semanticization is a process where episodic memories become more general and lose specific details transforming into semantic memories
Encoding specificity is the principle that learning and retrieval are more successful when the context of learning and retrieval match
Parietal lobe is crucial for short-term memory (STM), indicated by its damage affecting performance on tasks like digit span and recall of recent information
Semantic memory refers to general knowledge and facts, while episodic memory relates to personal experiences and events.
People often mistakenly identify similar sentences as previously read, indicating that semantic meaning is encoded in memory, not just sound and structure of words.
