    Study Notes

    Visual Perception Concepts

    • Orientation Constancy: The ability of the visual system to maintain a consistent perception of an object's orientation despite changes in the viewer's perspective or the object's position.
    • Size Constancy: The ability of the visual system to maintain a consistent perception of an object's size despite changes in the viewer's distance or the object's distance from the viewer.

    Top-Down Influence

    • The IT (Inferotemporal) area is affected by top-down influence, which means that higher-level cognitive processes can influence earlier stages of visual processing.

    Contour Integration

    • Contour Integration: The process of combining simple features, such as line segments, into a unified percept of a complete object or shape.

    Lateral Occipital Complex (LOC)

    • The LOC is specified for object recognition, which is the ability to identify and categorize visual objects.

    Developmental Visual Processing

    • Processing Contours for static Displays develops at around 4-6 months of age, indicating that infants at this stage can start to perceive and process simple shapes and contours.

    Neuronal Processing

    • Complex cells are the type of neurons for which bottom-up processing is not sufficient, requiring additional top-down processing to accurately respond to visual stimuli.

    Bottom-Up Processing

    • Bottom-up processing is a type of visual processing that starts with the analysis of simple features, such as lines and edges, and progresses to more complex representations of visual objects.

    Object Recognition Theories

    • Biederman's Recognition-by-Components (RBC) theory states that objects are recognized by breaking them down into simple geometric components, such as edges, lines, and vertices, and matching these components to stored representations.

    Visual System Overview

    • The visual system is a complex network of brain areas and pathways that work together to process and interpret visual information from the environment.
