    Study Notes

    Signal Detection and Perception

    • Changes in auditory and visual stimuli can be detected at specific thresholds known as absolute limen, the point at which a stimulus goes from undetectable to detectable.
    • Within detected stimuli, the difference limen refers to the minimum intensity change required to notice a difference, such as increasing sound volume beyond which it becomes uncomfortable, known as terminal limen.
    • Just noticeable difference is crucial for marketing psychology, as seen in branding strategies like the transition of Lexmark printers connected to IBM's identity.

    Brand Perception Examples

    • The rebranding of products, like laser printers, shows how noticeable differences in design (size and space) influence consumer memory and brand association.
    • Betty Crocker’s gradual change in brand ambassadors from 1936 to 1996 illustrates subtlety in marketing, maintaining consumer familiarity with slight alterations in appearance.

    Perceptual Cycle Model

    • U. Neisser's perceptual cycle model combines bottom-up and top-down processes for understanding perception, attention, and categorization.
    • Differentiation between figure (the object of focus) and ground (the background) is essential for meaningful perception, affecting how we recognize items visually.

    Signal Detection Theory

    • Originating from communication and radar systems, this theory addresses human sensitivity to stimuli, especially under weak signal conditions.
    • The grid system of responding to signals (presence vs. absence) creates scenarios of hit (correct response) and false alarm (incorrect response), emphasizing the need to discern signals from noise.

    Visual Depth and Perception

    • Monocular cues, such as interposition (when one object blocks another) and shadow patterns (luminance and contrast), help gauge depth and height in visual fields.
    • Understanding depth cues is critical in recognizing spatial relationships and the size of objects based on their visual presentation.

    Practical Applications

    • Knowledge of perceptual psychology assists in marketing, design, and visual comprehension, enhancing product positioning and consumer engagement.
    • Subtle adjustments in brand representation can lead to significant perceptual impact, keeping the overall identity intact while refreshing the brand's image.
