What is top-down and bottom-up examples?
Bottom-Up vs.
Bottom-up processing begins with the retrieval of sensory information from our external environment to build perceptions based on the current input of sensory information. Top-down processing is the interpretation of incoming information based on prior knowledge, experiences, and expectations.
Why is bottom-up approach better?

What is a real life example of top-down processing?
One classic example of top-down processing in action is a phenomenon known as the Stroop effect. In this task, people are shown a list of words printed in different colors. They’re then asked to name the ink color, rather than the word itself.
What is the difference between top-down and bottom-up approaches to personality?
The top-down model assumes that life-satisfaction has a global halo effect on satisfaction with specific life domains. In contrast, bottom-up model consider life-satisfaction judgments to be summary judgments of satisfaction with important life domains (Schimmack, Diener, & Oishi, 2002).
