Questions and Answers

What is a key characteristic of long-term memory as opposed to short-term memory?

It has a limited storage capacity.

It only retains sensory information.

Information is lost rapidly.

It allows for retrieval of stored information. (correct)

Which type of memory appears to remain intact in individuals with certain brain damage?

Long-term memory prior to the injury (correct)

Working memory during the injury

Sensory memory after the injury

Short-term memory before the injury

What effect did counting backward have on the recall of initial material in the study mentioned?

It increased retention of new information.

It enhanced recall significantly.

It prevented almost all the material from reaching long-term memory. (correct)

It had no effect on short-term memory.

How does the serial position effect influence memory recall?

Early items in the list are often remembered better due to the primacy effect. Signup and view all the answers

Which statement best describes the nature of short-term memory based on the provided content?

It retains information only for a brief amount of time. Signup and view all the answers

What conclusion can be drawn from the laboratory experiments regarding short-term memory?

The decline in recall after a short duration suggests separate memory types. Signup and view all the answers

Why do people with brain damage have difficulty recalling new information after the injury?

Short-term memory remains operational, but new entries cannot be stored. Signup and view all the answers

What was the result of varying the time interval before the recall of initial material in the studies discussed?

Recall significantly dropped after a 15-second delay. Signup and view all the answers

What inference can be made from the observation that individuals retain memories prior to brain injury but struggle with new information afterwards?

It suggests that there are distinct systems for short-term and long-term memory. Signup and view all the answers

How does the research involving counting backward illustrate the limitations of short-term memory?

Counting backward diverts attention, preventing information from transferring to long-term memory and causing rapid decay of short-term recall. Signup and view all the answers

What role does the primacy effect play in the understanding of memory recall?

The primacy effect highlights that items presented early in a list are often recalled better than those presented later. Signup and view all the answers

What conclusion can be drawn from the findings on the recall rates after a 15-second interval?

Recall rates drop to around 10 percent after 15 seconds, indicating that short-term memories deteriorate quickly without reinforcement. Signup and view all the answers

In what way do the findings on memory support the existence of separate memory systems?

The distinct patterns of recall in short-term versus long-term memory demonstrate that they operate through different processes. Signup and view all the answers

How can brain damage support theories about memory systems?

Observations of brain-damaged individuals retaining old memories while failing to recall new ones provides evidence for separate memory mechanisms. Signup and view all the answers

What implications do the studies on memory suggest about the encoding process?

The studies imply that effective encoding is crucial for moving information from short-term to long-term memory. Signup and view all the answers

Why is understanding the differences between short-term and long-term memory significant in cognitive psychology?

Understanding these differences aids in developing strategies for improving memory and addressing memory impairments. Signup and view all the answers

Study Notes

Long-Term Memory

Long-term memory has almost unlimited capacity, like a large hard drive
Information is filed and coded for retrieval
Brain damage can result in loss of new information but old memories intact, showing distinct storage systems
Short-term memory still functions though, proving two different types of memory

Short-Term Memory

Short-term memory holds information briefly, like temporary files
Experiments using recall tasks (memorizing, reciting) reveal short timeframes for the information to stay in short-term memory
If distraction occurs, recall rate of short-term information drops rapidly after 15 seconds. Distraction prevents entry into long-term memory.

Serial Position Effect

Information recall varies depending on the list position
Primacy effect: items presented at the beginning of the list are better recalled
Recency effect: items later in the list (recent) are recalled better
