What is long-term memory (LTM) responsible for?
Long-term memory is a system responsible for storing information for long periods of time, ranging from a few moments ago to as far back as we can remember. It acts as an archive of past events and learned knowledge.
How does long-term memory differ from short-term memory in terms of time span?
Short-term memory/working memory retains information for about 30 seconds or less, while long-term memory spans from minutes ago to decades earlier, covering both recent and remote memories.
How does long-term memory interact with working memory in everyday understanding?
Working memory holds current information (e.g., the wording of a sentence), while long-term memory supplies meaning and background knowledge (e.g., facts about James Bond, movies, or people mentioned). This interplay allows comprehension and interpretation of ongoing experiences.
Why is long-term memory not just about storing information?
While LTM retains past information, it also supports dynamic processes by interacting with working memory. This enables us to interpret, understand language, solve problems, and make decisions in real time.
What classic experiment studied the distinction between short-term and long-term memory?
B.B. Murdoch Jr. (1962) studied the distinction between STM and LTM by measuring the serial position curve, which shows how recall varies depending on an item’s position in a list.

What is a serial position curve and how is it created?
A serial position curve is created by presenting a list of words to participants one at a time. After the last word, participants recall as many words as they can in any order. The curve plots recall percentage versus the word’s position in the list.
What does the serial position curve reveal about memory performance?
It shows that memory is better for words at the beginning (primacy effect) and end (recency effect) of the list than for words in the middle.
What is the primacy effect in memory recall?
The primacy effect is the tendency to better recall words presented at the beginning of a list. It occurs because early words receive more rehearsal time, which allows transfer into long-term memory.
How did Rundus (1971) test the explanation for the primacy effect?
Rundus presented lists of 20 words at 5-second intervals. In one condition, participants repeated words aloud during the intervals. Words rehearsed more often (earlier items) were recalled better, supporting the idea that rehearsal time underlies the primacy effect.
What is the recency effect in memory recall?
The recency effect is the tendency to better recall words presented at the end of a list. It occurs because the most recent items are still stored in short-term memory.
How did Glanzer and Cunitz (1966) test the recency effect?
They asked participants to recall words after counting backwards for 30 seconds immediately after the last word. The counting prevented rehearsal and eliminated the recency effect, showing it depends on items being stored in short-term memory.
