Observer Perspective
• Another distortion in visuospatial processing
• People tend to subjectively stretch area around them and shrink other areas
• Report distance from familiar place to unfamiliar place to be longer than reverse
• E.g., Perspective from NYC

Propositional vs. Depictive
• Propositional– The globe is on the desk
– ON (GLOBE, DESK)
• Depictive

Propositional vs. Depictive• Issue: Is the representation that underlies imagery propositional or depictive?

Demand Characteristics?
• Perhaps subjects think you want them to act like they’re scanning an image, so they act that way– Subjects infer the experimenter’s implicit demands
• Or perhaps experimenters expect a certain set of results and this biases results
• But get similar results when experimenters and subjects told that theory predicts scanning short distances takes longer

Imagery isn’t just like perception
• Perception has metric qualities that images don’t
• Example: Bisected rectangle with diagonal lines

Ambiguous Figures
• That figure was actually ambiguous
• Using imagery: What else could that figure have been?
