Question 43

Information gradually fades over time because it is not used.

The decay theory of forgetting suggests that memories fade and are lost over time if they are not actively recalled or used. This means that without reinforcement or retrieval, information can diminish in strength and clarity.

A) current information is lost because of interference from previous learning

This option describes interference theory rather than decay theory. Interference theory posits that newer information can disrupt the retrieval of older memories, which is distinct from the idea that memories simply fade away over time due to lack of use.

B) previously learned information is lost because of interference from current information

Similar to Option A, this statement aligns with interference theory. It states that existing memories can be overshadowed or lost due to newer information, contradicting the principle that decay occurs through the passage of time without active engagement.

C) information is lost because it exceeds the capacity of short-term memory

This option refers to the limitations of short-term memory capacity and does not pertain to the decay theory. Decay theory focuses on the gradual fading of information over time, independent of the limitations of memory storage.

D) information gradually fades over time because it is not used

This is the essence of the decay theory, which asserts that without retrieval or use, memories will naturally diminish in strength and clarity over time. It highlights the importance of active engagement in retaining information.

E) some memories are stored in the unconscious, making them difficult to retrieve

This option addresses the concept of unconscious memory and retrieval difficulties, which is not relevant to decay theory. Decay theory specifically deals with the fading of memories over time, rather than issues related to unconscious storage.

Conclusion

The decay theory of forgetting is accurately represented by option D, which emphasizes the gradual loss of information over time due to lack of usage. All other options either describe different theories of forgetting, such as interference, or fail to align with the fundamental principles of decay theory, making D the only correct choice.
