    Study Notes

    Attention

    • Attention is selective, focusing on specific details while overlooking others, as demonstrated by the change blindness effect, a card trick that shows how our attention can be deceived.

    Change Blindness

    • Change blindness is an illusion that occurs when there is an interruption in viewing an image, allowing for changes to go unnoticed.
    • Saccades (rapid eye movements) that occur multiple times per second during normal vision can cause this interruption.
    • During saccades, the brain suppresses visual information, maintaining visual continuity and allowing for efficient visual exploration.

    Visual Suppression

    • Visual suppression is a process that temporarily suspends visual processing during rapid eye movements, maintaining visual continuity and facilitating seamless transitions between points of interest.
    • This process minimizes disruptions in visual input, allowing for selective processing of relevant visual stimuli.

    Limited Cognitive Resources

    • Attentional resources are limited, and our brain prioritizes stimuli for processing, as described by Daniel Kahneman's theory.
    • Attentional allocation can be influenced by task demands, salience of stimuli, and individual goals, but is ultimately constrained by the limited capacity of the human mind.

    Attention to Space

    • Spatial allocation of attention allows us to focus on relevant information while filtering out distractions.
    • Spatial attention can be thought of as a spotlight, illuminating specific regions of space while leaving others in relative darkness.

    Spatial Attention

    • Research suggests that spatial attention is more nuanced and adaptable than initially thought, with experts in different sports exhibiting distinct attentional spotlights shaped by their respective activities.
    • Attentional focus and eye movements are intricately related, with attention potentially anticipating eye movements.

    Attention to Features

    • Donald Broadbent's work introduced the concept of diotic listening, which explores how individuals manage attention when faced with information overload.
    • This method has been used to study how attention is allocated to different features or stimuli.
