This diagram comes from a study by Glanzer and Cunitz (1966) who looked at the effect of delay on recall. This shows three serial position curves for a task like the one we did in clas where you had to recall 20 words in any order. In one of these curves, there was no delay before recall. In one there was a 10 second delay and in one there was a 30 second delay. What do these curves demonstrate? .70 .60 .40 30 .20 10 POSITION O The primacy effect is reduced or even eliminated with a delay. O The primacy effect is enhanced with a delay. O The recency effect is enhanced with a delay. O The recency effect is reduced or even eliminated with a delay. PROPORTION CORRECT

Question
This diagram comes from a study by Glanzer and Cunitz (1966) that investigated the effect of delay on recall. It shows three serial position curves for a task involving the recall of 20 words in any order. The curves represent different conditions: one with no delay before recall, one with a 10-second delay, and one with a 30-second delay. The question posed is: What do these curves demonstrate?

**Graph Explanation:**

- **X-Axis:** Represents the position of words (1 to 15) in the sequence.
- **Y-Axis:** Represents the proportion of words recalled correctly, ranging from 0.20 to 0.70.

The graph includes three different curves:

1. **Solid Line (No Delay):** This line shows higher recall at both the beginning and the end of the list, demonstrating both primacy and recency effects.
2. **Dashed Line (10-Second Delay):** This line exhibits a reduced recency effect compared to the no-delay condition, but the primacy effect is relatively intact.
3. **Dotted Line (30-Second Delay):** This line shows a further reduction in the recency effect, with the primacy effect still apparent.

**Question: What do these curves demonstrate?**
- The options provided suggest examining changes in primacy and recency effects.
- The curves illustrate that the recency effect is reduced or eliminated with a delay.

**Answer Choices:**
- The primacy effect is reduced or even eliminated with a delay.
- The primacy effect is enhanced with a delay.
- The recency effect is enhanced with a delay.
- The recency effect is reduced or even eliminated with a delay. 

The most accurate answer would be that the recency effect is reduced or even eliminated with a delay.
