Long-term memory is sometimes unreliable because of _______ of information.

A) reconstruction
B) retention
C) coding
D) chunking

Long-term memory is prone to reconstruction because the process of retrieval involves bringing back stored information and integrating it with new experiences and information. During this process, memories can be altered or distorted, leading to errors and inaccuracies in recall. This is known as the misinformation effect, and it is one of the reasons why long-term memory is sometimes unreliable. Retention, coding, and chunking refer to other processes involved in memory storage and retrieval, but they do not directly contribute to the unreliability of long-term memory.
