Embrace the present, but remember the past shapes your perspective.

Cognition and perception are intricately linked to both memory and present experiences. Rather than solely reflecting on past events, memory serves as a tool for understanding the present and foreseeing the future. This dynamic process involves selectively retrieving relevant information from past experiences to navigate current situations. Our perceptions are influenced by expectations formed from previous knowledge, which can lead to phenomena like change blindness, where critical aspects of the environment go unnoticed due to preconceived notions. Memory, whether semantic or episodic, is fundamental for situational awareness and providing context—it allows individuals to discern important details while filtering out redundancy. This interplay between memory and perception equips us to recognize surprises in our environment, reinforcing that while we are aware of the present, our comprehension is deeply informed by our past experiences.
