Our perceptions are influenced by physical, environmental, and learned factors. Physical factors include our senses and brain processing, while environmental factors refer to the available information and context. Learned factors like culture, personality, and habits shape the filters we use to process information. Perception can also be impacted by ambiguity and influenced differently across cultures - for example, the color red may signify stop, anger, or good fortune depending on one's culture. We are constantly bombarded with sensory data, so our minds selectively attend to information that grabs our attention through strong stimuli, elicits emotion, is unexpected or fits patterns, connects to prior knowledge or interests, or is useful.
