A teacher shows a blurry image of a familiar object to the class and asks students to identify it. Despite the lack of clear details, many students quickly recognize the object as a stop sign. Which of the following best explains why they were able to identify the object.
A: Top-down processing – they relied on prior knowledge and expectations to interpret the image
B: Bottom-up processing – they analyzed the image’s individual features before recognizing the object
C: Sensory Adaptation – the retina became less sensitive to the blurry details over time
D: Selective Attention – they focused on the parts of the image that stood out the most
