Final answer:
Long-term memory (LTM) has an unlimited capacity and retains information that occurred more than a few minutes ago. The ability to retrieve information from LTM can be affected by memory trace decay and proactive interference.
Step-by-step explanation:
Long-term memory (LTM) is a continuous storage system with an unlimited capacity. It retains information that occurred more than a few minutes ago. LTM can be divided into explicit and implicit memory. Explicit memory refers to memories that we consciously try to remember and recall, such as facts or events. Implicit memory, on the other hand, consists of memories that are not part of our consciousness.
In terms of duration, long-term memory can last for a lifetime. However, the ability to retrieve information from LTM can be influenced by factors like memory trace decay and proactive interference. Memory trace decay occurs when the memory trace becomes less activated over time, leading to forgetting. Proactive interference happens when previously learned information interferes with the ability to learn new information.
