What is the key difference between the direct perception theory and the constructive perception theory in terms of their focus?
- Direct perception theory focuses on the neural hierarchy processing increasingly complex stimuli, while constructive perception theory focuses on basing one perception on another.

Study Notes
Theories of Perception
- Constructive perception theory emphasizes top-down processing, where individuals actively shape perceptions using expectations and prior knowledge.
- Direct perception theory focuses on how sensory information directly leads to perception without the influence of past experiences.
Ebbinghaus Size Illusion
- The perception of an object's size, like an orange circle, is influenced by surrounding objects, such as black circles, altering the perceived size through contextual comparison.
Recognition-by-Components (RBC) Theory
- Proposed by Biederman, RBC theory suggests that objects are recognized by analyzing their basic three-dimensional components (geons) and their configurations.
Modern Psychological Perspective
- The contemporary view emphasizes the significant role of experience and context in shaping perception, recognizing that prior knowledge and expectations play a crucial role.
Depth Perception Cues
- Certain perceptual cues, like texture gradient or linear perspective, contribute to the perception of depth; others may not have been specifically mentioned.
Factors Determining Perceived Size
- The perceived size of an object is primarily determined by context, relative size, distance, and surrounding elements that influence visual interpretation.
Light-from-Above Heuristic
- The light-from-above heuristic is a perceptual assumption that visual scenes are illuminated from above, influencing how shadows are interpreted.
Semantic Regularities in Perception
- An example of semantic regularity involves recognizing familiar contexts or scenarios that inform how objects are perceived based on learned associations.
Gestalt Psychology Principles
- Gestalt principles, such as proximity or similarity, influence how we group and perceive objects, leading to distinct interpretations of visual data.
Bottom-Up vs. Top-Down Processing
- Bottom-up processing involves perception that starts with sensory input, while top-down processing relies on cognitive factors like context and expectations.
Main Message on Processing
- The discussion emphasizes the interplay between bottom-up and top-down processing in perception, illustrating how both processes work together to shape human experience.
Heuristics for Visual Input
- Key heuristics, like the principle of parsimony and other mental shortcuts, aid in interpreting ambiguous visual information efficiently.
Simple vs. Complex Cells
- Simple cells in the striate cortex respond to specific orientations and locations of stimuli while complex cells are more sensitive to motion and can respond to stimuli across a larger area.
Role of Illusions
- Illusions highlight the complexities and limitations of visual perception, demonstrating how the brain can misinterpret sensory information.
Perception and External World
- The relationship between perception and the external world is characterized by a dynamic interaction where perceptions are not merely reflections of the outside world but are influenced by cognitive processes and experiences.
