Study Notes
Fundamental Processing of Human Perception
- Two main types of processing: Bottom-up and Top-down
- Bottom-up processing involves identifying parts, combining them, and then achieving recognition.
- Top-down processing starts from the brain, utilizing prior knowledge and expectations to interpret sensory information.
Bottom-Up Processing
- Begins at sensory receptors and moves to the brain.
- Recognition is direct and not influenced by complex thought processes.
- Theories include:
- Direct perception theory (Gibson, 1966)
- Template theories
- Feature-matching theories
- Recognition-by-components theory (Biederman, 1987)
Gibson’s Theory of Direct Perception
- Proposes that sensory receptors provide all necessary information for perception.
- Emphasizes ecological perception through texture gradients, indicating depth and distance without needing complex reasoning.
Transduction
- The process of converting sensory stimuli into signals for the brain.
- Requires both qualitative (basic qualities) and quantitative (degree/magnitude) information about stimuli.
Perception Explained
- Perception is an experience from sensory stimulation and is shaped by environmental information.
- Relies on context and learned experiences to construct meaningful interpretations.
Gestalt Principles of Organization
- Developed by Gestalt psychologists in the 19th century, counteracting structuralism's view of perception.
- Gestalt means “organized whole,” emphasizing the brain's intrinsic laws for grouping perceived features into wholes.
- Principles illustrate how perception is not simply the sum of its parts.
Recognition-by-Components (RBC) Theory
- Focused on Geons: simple, viewpoint-invariant geometrical shapes.
- Addresses how objects can be identified from their components regardless of viewpoint.
- Does not fully explain recognition of specific objects sharing the same geons.
Top-Down Processing
- Operates by constructing perceptions from prior knowledge and cognitive processes.
- Allows for quicker identification of objects within expectations, potentially leading to misinterpretations.
- Influenced by context effects, where environmental cues shape perception.
Context and Semantic Regularities
- Contextual surroundings significantly affect how stimuli are perceived.
- Semantic regularities are characteristics related to the functions of various scenes, influencing object perception based on prior knowledge.
- Scene schema contributes to expectations, aiding in the identification of objects in typical environments.
Overall Structure of Content
- The text covers Sensation and Perception, detailed theories of object perception, and the neural pathways involved in perception.
- Also addresses deficits of perception in dynamic contexts.
