Glanzer and Cunitz 1966 Support for MSM

Question 1

Aim

Answer 1

Investigate the serial effect position, with two separate stores of memory

Question 2

Experiment 1

Answer 2

Investigated LTM

Question 3

Participants #1

Answer 3

240 men enlisted in the army

Question 4

Method Info #1

Answer 4

5 Different Conditions
2 Variables:
-Learning Time
-Repetition of list

Question 5

Method Procedure #1

Answer 5

• Men in the different conditions were asked to immediately recall words after the presentation

Question 6

Results

Answer 6

• Results demonstrated that repetition of the lists had no effect on recall
• Spacing time demonstrated more time for rehearsal of the words
• Demonstrated Primacy effect

Question 7

Primacy Effect

Answer 7

Participants were able to recall more words at the beginning of the list because they had more time to rehearse the words

Question 8

1 Support for MSM

Answer 8

• Distinguishes different memory stores

- Rehearsal consolidates new information in LTM

Question 9

Experiment #2

Answer 9

Investigated STM

Question 10

Participants #2

Answer 10

46 Army enlisted men

Question 11

Method info #2

Answer 11

-15 word list
Conditions
- Recall immediately
-10 second recall (after interference task)
-30 second recall (after interference task)

Question 12

Method Procedure #2

Answer 12

46 participants were shown different variations of a 15 word list
-Different conditions of interference task

Question 13

Results #2

Answer 13

Participants with greater interference task resulted in less word recall (info displacement
-Removed the recency affect associated with STM

Question 14

Recency effect

Answer 14

Tendency to recall information most recently presented

Question 15

Conclusion

Answer 15

Both experiments support the hypothesis of two distinct storage mechanisms

Question 16

Conclusion #1

Answer 16

-Demonstrated by the increase in primacy effect when delay was increase

Question 17

Conclusion #2

Answer 17

-Decrease in recency effect when delay and interference prevented rehearsal

Question 18

Limitations

Answer 18

• Participant “mental” capacity not taken into consideration
• Low ecological validity
• Participants were all males

Question 19

Strengths

Answer 19

• Support MSM
• Tightly controlled lab design, limiting extraneous variables
• Repetition of the experiment, have demonstrated similar results (reliability)
