    Study Notes

    Visual Imagery

    • What is mental imagery? Forming mental images, even without the physical stimulus. Experiencing sensory impressions without sensory input.

    • Types of Visual Imagery:

      • Visual imagery: "seeing" without a visual stimulus (e.g., describing a face).
      • Other senses also have mental imagery (e.g., smell, taste, touch).

    The Imagery Debate: Spatial vs Propositional

    • Spatial vs Propositional Representations:
      • Debate about the underlying representation in the mind.

    Visual Imagery: Shepard & Metzler (1971) Mental Rotation Experiment

    • Experiment: Participants judged if shapes were the same object rotated, or different objects.
    • Measurements: Reaction time (RT) to compare objects depending on rotation angle.
    • Findings:
      • Longer RT for objects needing greater rotation.
      • Supports the idea of mental rotation.
      • Linear relationship between reaction time and angle of orientation.

    Visual Imagery: Image Scanning

    • Experiment (Kosslyn, 1980, 1994): Participants mentally scanned a spatial map.
    • Measurements: Reaction time depending on distance between locations on the mental image.
    • Findings:
      • Longer reaction times for scanning further distances. Indicating spatial representations during image scanning.
      • Further support for the idea that imagery uses spatial representations.

    Imagery & Perception

    • Both imagery and perception share similar mechanisms in the brain, but imagery might be less vivid and longer lasting.
    • The spatial layout of the stimulus is the same (in perception and imagery).

    Imagery & Memory

    • Paivio's Dual-Coding Theory: Memory is improved if information is encoded both visually & verbally.

    • Paired-associate learning: Memory for concrete words (evoking mental images) is better than abstract words.

    • Using imagery to improve memory:

      • Visualizing Interacting Images: Visualizing interacting images improves memory more than non-interacting images, especially bizarre ones.
      • Organizational Effect of Imagery: The "Method of Loci" uses a mental map to help remember ordered information.
    • Pegword method uses rhyming to link items.

    Imagery & The Brain

    • Evidence from ERP's, Brain Imaging, Imagery Neurons, and Neuropsychological Case Studies (e.g., transcranial magnetic stimulation):
      • The occipital lobe, especially area V1 is important in imagery.
      • Some neurons fire specifically when processing images.
      • Damaging parts of the visual cortex impacts the ability to do imagery tasks.
