    "subtitle": null,
    "abstract": "Mathematical competence requires pattern recognition for appropriate application of concepts and procedures. Research\ndemonstrates that interventions targeting perceptual learning (PL) improve math performance. Little research, however,\nhas directly investigated encoding changes, measured psychophysically, that may accompany PL gains in real-world tasks. We\nsought evidence of lasting encoding changes for mathematical objects for participants who used an Algebraic Transformations\nPLM and compared them to a Control group who did a different task, one that did not target PL of equation structure, but provided\nequal exposure to the same equations as in the PLM. All participants completed a speeded same/different psychophysical\ntask comparing equations at pretest and delayed posttest. The PLM group improved on the psychophysical task more than\ncontrols, demonstrating that PLM structure, not mere exposure to equations, caused the information encoding gains. Perceptual\nlearning interventions can accelerate expertise in complex domains, and these learning gains produce detectable, durable\nencoding changes.",
