Glanzer and Cunitz Study Quiz

What was the primary aim of Glanzer and Cunitz's study on the primacy and recency effects?

Answer explanation

The primary aim of Glanzer and Cunitz's study was to investigate the primacy and recency effects in memory, demonstrating how items presented at the beginning and end of a list are recalled better than those in the middle.

What was the experimental design used in this study?

• independent measures

• repeated measures

• matched pairs

Answer explanation

The researchers used a repeated measures design

What was the purpose of the distractor task in the delayed recall condition?

Answer explanation

The purpose of the distractor task in the delayed recall condition was to prevent rehearsal of the information, thereby assessing the true retention of memory without interference from immediate recall.

How did the researchers ensure that recall was only influenced by the conditions of STM and LTM?

Answer explanation

The researchers controlled variables by standardizing the tasks and environments for both STM and LTM, ensuring that any differences in recall could be attributed solely to the conditions of these memory types.

What did the researchers find about the recall of words at the beginning of the list?

Answer explanation

The researchers found that words at the beginning of the list were recalled better than those in the middle or at the end, demonstrating the primacy effect in memory recall.

What did the researchers find about the recall of words at the end of the list in the immediate recall condition?

Answer explanation

The researchers found that words at the end of the list were recalled better in the immediate recall condition, demonstrating the recency effect, where the last items are more easily remembered.

What happened to the recency effect in the delayed recall condition, and why?

Answer explanation

In the delayed recall condition, the recency effect diminishes or disappears. This occurs because the last items are no longer fresh in memory due to the delay, reducing their accessibility during recall.

How did the study demonstrate the existence of two separate memory stores?

Answer explanation

The study demonstrated the existence of two separate memory stores by showing that different types of information (e.g., verbal and visual) were processed and recalled independently, indicating distinct memory systems.

What did Glanzer and Cunitz conclude about the primacy and recency effects?

Answer explanation

Glanzer and Cunitz concluded that the primacy effect is due to better recall of items presented at the beginning of a list, while the recency effect is attributed to items at the end, showing distinct memory processes for each.

How does this study support the Multi-store Model of Memory?

Answer explanation

This study supports the Multi-store Model of Memory by demonstrating how information is processed through distinct stages: sensory memory, short-term memory, and long-term memory, aligning with the model's structure.
