Correct option is A
Statement I: "Bottom-up processes involve information or input-driven cognitive processes" (True)
Bottom-up processing refers to a data-driven approach where perception begins with raw sensory input from the environment.
The brain constructs meaning step-by-step, starting from basic sensory information (e.g., shapes, colors, sounds).
Example: Identifying an unfamiliar object based purely on its features (edges, colors, texture).
Statement II: "Cognitive processes that are driven by the organism's prior knowledge and expectations are known as top-down processes" (True)
Top-down processing is concept-driven, where the brain interprets sensory input based on prior experiences, expectations, and knowledge.
It helps in recognizing familiar objects, words, and situations quickly.
Example: Reading a blurred sentence and still understanding it because of previous knowledge of language.
Since both statements accurately describe Bottom-up and Top-down processing, option 1 is correct.
Information Booster:
-Bottom-up Processing: Sensory-driven, starting with raw data (e.g., recognizing a new sound).
-Top-down Processing: Knowledge-driven, influenced by prior experience (e.g., understanding handwriting despite missing letters).
-Example of Bottom-up Processing: Seeing an unfamiliar animal and identifying it based on its shape and color.
-Example of Top-down Processing: Recognizing a friend in a crowd even if their face is partially obscured.
-Role of Attention:
---Bottom-up attention is automatic and stimulus-driven (e.g., reacting to a loud noise).
---Top-down attention is goal-directed and intentional (e.g., focusing on a lecture despite background noise).
-Applications in AI and Neuroscience:
---Bottom-up processing is used in image recognition and sensory perception models.
---Top-down processing helps in decision-making and context-based AI responses.
