Artificial Intelligence
Artificial Intelligence☜A collaboratively editable version of Robert Horns brilliant and pioneering debate map Can Computers Think?—exploring 50 years of philosophical argument about the possibility of computer thought.☜F1CEB7

⇤
Top-down image processing has been implemented
Top-down image processing has been implemented☜Top-down processing of imagery has been formally described using a theory of processing subsystems. The theory is mathematically precise enough to be simulated in computer programs that recognise patterns by a process of top-down hypothesis testing.☜FFFACD
⇤
Quasi-pictorial images are adequate
Quasi-pictorial images are adequate☜An adequate theory of mental activity can be formed without assuming an underlying proposition or deep structure. Quasi-pictorial images can do the same work as symbolic descriptions.☜FFFACD
⇤
Images are Quasi-pictorial representations
Images are Quasi-pictorial representations☜Images are quasi-pictorial entities with special properties that correspond to those of their correlated physical objects. Images possess structure by virtue of their ties to higher-perceptual processes.☜FFFACD
⇤
Experimental evidence
Experimental evidence☜Kosslyn argues that image psychology is supported by experimental evidence.☜FFFACD
⇤
Mental Rotation
Mental Rotation☜Subjects rotated images in their heads in much the same way that they would rotate physical objects in space. Conclusion: the mental image being rotated has spatial properties analogous to those of an object.☜FFFACD
⇤
Scanning visual images
Scanning visual images☜The time needed for subjects to describe mental images corresponds to the time it would have taken them to scan an actual picture. Conclusion: internal images have special properties analogous to those external images. ☜FFFACD
⇤
Alleged problems have been disconfirmed
Alleged problems have been disconfirmed☜Task demands and experimenter effects do not refute scanning and rotation experiments (see detailed text).☜FFFACD
⇤
Behavioural evidence favours image psychology
Behavioural evidence favours image psychology☜Image psychology predicts image rotation and scanning in addition to explaining them. Propositional theory, by contrast, does not predict image rotation and scanning.☜FFFACD
⇤
Impenetrability doesn’t isolate basic elements
Impenetrability doesn’t isolate basic elements☜The requirement that basic elements of functional architecture must be cognitively impenetrable is flawed as many body functions—eg digestion—are cognitively penetrable but still basic, and elements can change levels in the functional hierarchy.☜FFFACD
⇤
Images important even if not primitive explanations
Images important even if not primitive explanations☜It may be true that images are not primitive, low-level entities. However, explanation does not always require an understanding of what happens at the lowest possible level. The proper level of analysis perception requires the inclusion of images.☜FFFACD
⇤
Simulation suggests image theory precision
Simulation suggests image theory precision☜Images can be precisely described computational data structures. This is not just a vague picture in the head metaphor, because operations on these data structures (such as rotation and scanning) can be simulated on a computer.☜FFFACD
⇤
Pylyshyn uses wrong notion of an image
Pylyshyn uses wrong notion of an image☜Pylyshyn attacks an extreme picture-in-the-head theory of images that views images as mental photographs. But photographs lack intrinsic structure. Mental images, in contrast, are richly structured entities that still have some spatial properties.☜FFFACD
⇤
Machine implementations show computational power
Machine implementations show computational power☜Computer models based on a visual buffer have been highly successful at a variety of tasks, even to the point of being able to solve problems they were not originally programmed for. Such success could not result from an incoherent theory.☜FFFACD
⇤
Regard mind's eye as a classification scheme
Regard mind's eye as a classification scheme☜The minds eye need not be interpreted as a location in space. The minds eye is better thought of as a processor (or visual buffer) that interprets sensory information in a series of stages.☜FFFACD
