20. Which scenario illustrates long-term memory?

Answer: B

Explanation:

Knowledge of the family members favorite foods influences the persons choices as they walk through the grocery store.

This scenario exemplifies long-term memory as it demonstrates the use of previously acquired knowledge to guide decision-making in a real-time situation. The influence of the family member's favorite foods indicates the retention and application of information over an extended period.

A) Written information about a family members dietary restrictions is brought to the grocery store to be consulted.

While this scenario involves recalling specific information, it represents short-term memory usage since the individual is referring to written notes rather than relying on internalized knowledge. Thus, it does not illustrate long-term memory effectively.

B) Knowledge of the family members favorite foods influences the persons choices as they walk through the grocery store.

This choice accurately represents long-term memory as it involves the retention of information about the family member's preferences, which is applied to make informed choices. The ability to recall this information while shopping indicates that it has been consolidated into long-term memory.

C) Accidentally purchasing spoiled fruit at a grocery store causes a feeling of disgust each time the person visits that section of the same store.

Although this scenario reflects a learned emotional response, it primarily illustrates a form of associative memory rather than the recall of factual knowledge. The disgust felt is tied to a specific experience rather than a long-term retention of information.

D) Seeing that some favorite items are no longer available at a particular grocery store leads the person to go to a different one the following week.

This scenario indicates a change in behavior based on past experiences but does not highlight the retention of specific information about the family member's favorites. It suggests short-term decision-making rather than the use of long-term memory.

Conclusion

The correct answer, option B, effectively captures the essence of long-term memory by demonstrating the application of retained knowledge about preferences in a real-life context. In contrast, the other options either illustrate short-term memory processes or emotional associations, failing to represent the retention and application of information characteristic of long-term memory.
