1. Memory is the process of encoding, consolidating, storing, and retrieving information over time. It involves different areas of the brain and can be impacted by various factors. 2. There are three main types of memory: sensory memory, short-term memory, and long-term memory. Short-term memory only lasts a few seconds while long-term memory can last a lifetime. 3. Memory is not a perfect recording of events but rather a reconstructive process that can be influenced by suggestion, misinformation, and interference over time. Eyewitness testimony for example can be unreliable.
