Ambiguity/inconsistency catalyses ideas (+) Positive One or more paragraphs pp. 448–449 «When externalized and in the visual field, however, the very processes of vision—the way the eye moves and checks for consistency—typically drives them to see the ambiguity. When a structure is probed deeply enough, relations or interactions between parts, that were never anticipated may be easy to discover. Thus, an author may be able to discover interpretations he or she never considered.»
Perception infers abstract structures (+) Positive One or more sentences pp. 443–444 «Most people find it easier to think in terms of physical lines than in terms of the mental counterparts of lines, particularly the more lines there are, or the more complex the structure.»
Visuailzations clarify common ground (+) Positive One or more sentences p. 444 «When someone externalizes a structure, they are communicating with themselves, as well as making it possible for others to share with them a common focus.»
Visualizations aid in resuming (+) Positive One or more sentences pp. 447–448 «The brute fact of physical persistence, then, changes the reliability, the shareability, and the temporal dynamics of thinking. It is easier to have the same thought tomorrow, if the vehicles encoding the thought, or the cues stimulating the thought, are the same as today’s.»
Visualizations are external physical entities (+) Positive Basically all of the publication
Visualizations are globally stable (+) Positive One or more sentences p. 444 «What’s persistent outside, and in the visual or tangible field—an external structure holds a structure constant until it is added to; the structure does not decay the way mental structures and processes do, and it supports repeated perceptual inquisition;»
Visualizations are objects to reference (can be pointed to) (+) Positive One or more sentences p. 444 «One virtue of this particular annotation is that by having verbally defined the structure to be manipulated, and then visibly locating it on his body, the choreographer and anyone looking at the video, knows that if they refer to any visible part of the trapezoid their reference will be understood.»
Visualizations are open for interaction (+) Positive One or more sentences p. 446 «They [external representations] can be operated on in different ways; they can be manually duplicated, and rearranged.»
Visualizations are open for interaction (+) Positive One or more paragraphs p. 442 «…access to new operators—you can do something outside that you cannot inside…»
Visualizations drive attention (*) Mentioned without valuation One or more sentences p. 443 «It is natural for visual attention to focus on estimating angles.»
Visualizations enable application of visuospatial skills to abstract domains (+) Positive One or more paragraphs pp. 446–447 «Interaction has thus converted the world from a place where internal computation was required to solve the problem to one where the relevant property can be perceived or physically discovered. Action and vision have been substituted for imagery, projection, and memory.»
Visualizations enable progressive evaluation (+) Positive One or more sentences p. 450 «Without actually testing things in the physical world, it’s too hard and error prone to predict downstream effects.»
Visualizations enable to work on more complex conceptual structures (+) Positive One or more paragraphs p. 447 «As the descriptive complexity of the board state increases, there comes a point where it is hard, if not impossible, for someone to hold the complete structure in mind.»
Visualizations enable to work on more complex conceptual structures (+) Positive Less than a sentence p. 442 «…you can encode structures of greater complexity than you can inside…»
Visualizations provide an additional explanation (+) Positive One or more sentences p. 451 «Without interacting with multiple representations certain discoveries would simply be out of reach. Visual designers who move between pen and paper, 3D mockups and rapid prototypes are familiar with the same type of process.»
Visualizations reduce effort (+) Positive One or more sentences p. 442 «Cognitive processes flow to wherever it is cheaper to perform them.»
Visualizations re-represent structures (+) Positive One or more paragraphs p. 449 «Much external activity can be interpreted as converting expressions into more explicit formulations, which in turn makes it easier to ‘grasp’ the content they encode.»
Visualizations re-represent structures (+) Positive One or more sentences p. 444 «How information is encoded, both inside and outside in virtue of interaction. Because there is an external structure present, subjects can try out different internal and external representational forms, the two forms can play off each other in an interactive manner, leading to new insights.»
Visualizations serve to focuse/reorganize/explore thoughts (+) Positive One or more sentences p. 446 «By reordering and rearranging what is close to what, we change a token’s neighborhood; we change the space of what is cognitively near.»
Visualizations show additional relationships (*) Mentioned without valuation One or more sentences p. 443 «For instance, if two lines intersect then they define a set of angles.»
Visualizations support external memorization (+) Positive One or more sentences p. 445 «Everyone knows it is useful to get things out of the head and put where they can be accessed easily any time.»
Visualizations track provenance (+) Positive One or more sentences p. 446 «The power of physical rearrangement, at least for vehicles of propositions, such as sentences, logical formulae, pictorial narratives, is that it lets us visually compare statements written later with those written earlier;»
