    Study Notes

    Perception

    • Initial Processing: Perception starts with basic sensations before object recognition, within a timeframe of less than one second.
    • Organization: Perception involves organizing sensory information into meaningful objects and scenes, much like creating order from a kaleidoscope.
    • Bottom-up Processing: Perception is driven by basic visual features, which are innate and processed automatically.
    • Top-down Processing: Perception is influenced by prior knowledge and expectations, shaping what we anticipate seeing and how we process information.

    Ecological Approach

    • Affordances: Objects possess inherent "affordances" or potential uses, influencing our perception. We see coffee mugs and immediately associate them with the act of drinking coffee.
    • Direct Perception: Direct Perception argues that we directly perceive the meaning of objects and scenes without significant internal processing.

    Perceptual Inferences

    • Perceptual Computations: Perception involves complex computations that combine sensory data with prior knowledge and expectations.
    • Distinction between "Perceiving" and "Cognizing": There is a distinction between simply seeing and understanding the meaning of what we see.
    • Internal Representations: Our brain uses internal representations to decode and encode information about the world, allowing us to understand and interact with it.

    The Visual System

    • Retinal Projection: The 3D world is projected onto our 2D retinas, requiring our brains to interpret and reconstruct the image.
    • Fovea: The fovea, a central part of the retina, provides detailed information about the world. Our eyes constantly move to gather information and focus attention.
    • Limitations of the Retina: The retina only signals contrast between objects and their backgrounds, not the underlying physical properties.
    • Hardwired Processes: Some perceptual and cognitive processes are hardwired in the brain, remaining fixed and unchanging.

    Key Takeaways

    • Perception involves both bottom-up and top-down processes.
    • The ecological approach emphasizes the direct perception of affordances.
    • Perceptual inferences play a crucial role in our understanding of the world.
    • There is a clear distinction between seeing and understanding.
    • The visual system utilizes multiple processes and representations to make sense of the world.
