MENTAL IMAGERY --Is visual information stored in a visual or propositional (language- like code)?? -If visual, it should maintain spatial and perceptual characteristics of pictures (including the ability to re-interpret an image). -If more descriptional, then only information & characteristics that one had originally encoded should be evident (including one’s first interpretation). [Reisberg refers to depiction vs. descriptional ] --ways to study imagery: a-Introspection___________ (“looking inward”) b-Chronometric______________ Studies I. Quasi-Picture Theory (Shepard, Kosslyn, Finke) --mental images are Analog/ Geometric representations of visual stimuli; and are “functional isomorphs” to Euclidean space (Shepard) --visual imaging is functionally equivalent to seeing, with our “mind’s eye” A. Theoretical Claims ( Finke’s Principles*) 1. Spatial__Equivalence* : represent like pictures (not like sentences). Location, size, and distance are arranged in an image as they are in physical space. --spatial relations among objects in an array are preserved

2. Implicit_ Encoding* : spatial relations can be implicitly represented in a picture/ image (without explicit attention ever have been paid to the spatial relations). 3. Perceptual_ Equivalence* : imaging is like seeing (with a “mind’s eye”); the same ‘visual screen’ is used E.g., Perky’s (1910) tomato/leaf/banana experiment --the parts of visual images can be processed in parallel (whereas sentence elements are processed serially) 4. Transformational_ Equivalence* : images can be scanned, rotated, etc. in the same way as actual pictures or spatial stimuli E.g., “mentally” walking around one’s house --Eye movement patterns are the same when people image an object as when they perceive that object 5. Structural_ Equivalence* : the structure of Images is like that of actual perceived objects, and can be re-organized & re- interpreted. Images are analogous to 2-1/2 D sketches. --Images are assembled; assembly based on description
