Question: What American professor of cognitive science whose research focuses on the sense of "I" developed the Parallel terraced scan with John Rehling?

full_context: Document 1: Parallel play: Parallel play is a form of play in which children play adjacent to each other, but do not try to influence one another's behavior. Children usually play alone during parallel play but are interested in what other children are doing. This usually occurs after the first birthday. It usually involves two or more children in the same room who are interested in the same toy, each seeing the toy as their own. The children do not play together, but alongside each other simply because they are in the same room. Parallel play is usually first observed in children aged 2–3. An observer will notice that the children occasionally see what the others are doing and then modify their play accordingly. The older the children are, the less frequently they engage in this type of play. However, even older preschool children engage in parallel play, an enduring and frequent activity over the preschool years. The image of parallel play is two children playing side-by-side in a sandbox, each absorbed in his or her game, not interacting with the other. "This is considered an early stage in child development, characterized by egocentric behavior and the inability to decenter and coordinate with the activities of a 'playmate'".

Document 5: Pedagogical agent: A pedagogical agent is a concept borrowed from computer science and artificial intelligence and applied to education, usually as part of an intelligent tutoring system (ITS). It is a simulated human-like interface between the learner and the content, in an educational environment. A pedagogical agent is designed to model the type of interactions between a student and another person. Mabanza and de Wet define it as "as a character enacted by a computer that interacts with the user in a socially engaging manner". A pedagogical agent can be assigned different roles in the learning environment, such as tutor or co-learner, depending on the desired purpose of the agent. "A tutor agent plays the role of a teacher, while a co-learner agent plays the role of a learning companion".
Document 6: Stephen Wolfram: Stephen Wolfram (born 29 August 1959) is a British-American computer scientist, physicist, and businessman. He is known for his work in computer science, mathematics, and in theoretical physics. He is the author of the book "A New Kind of Science." In 2012 he was named an inaugural fellow of the American Mathematical Society.
Document 7: Scenario (artwork): Scenario is an Artificial Intelligence (AI) computer graphic interactive installation, directed by the artist Dennis Del Favero, and developed in collaboration with scriptwriter Stephen Sewell, AI scientist Maurice Pagnucco working with computer scientists Anuraag Sridhar, Arcot Sowmya and Paul Compton. It is a 360-degree 3D cinematic work whose narrative is interactively produced by the audience and humanoid characters. The title is a Commedia dell'arte term (ʃeˈnarjo) referring to the way dramatic action is dependent on the way actors and audience interact. "Scenario" was developed at the iCinema Centre for Interactive Cinema Research  at the University of New South Wales.
Document 8: Termite-inspired robots: Termite-inspired robots or TERMES robots are biomimetic autonomous robots capable of building complex structures without a central controller. A prototype team of termite-inspired robots was demonstrated by Harvard University researchers in 2014, following four years of development. Their engineering was inspired by the complex mounds that termites build, and was accomplished by developing simple rules to allow the robots to navigate and move building blocks in their environment. By following these simple rules, the robots could construct complex structures through a process called "stigmergy", without requiring constant human instruction or supervision.
Document 9: Douglas Hofstadter: Douglas Richard Hofstadter (born February 15, 1945) is an American professor of cognitive science whose research focuses on the sense of "I" (sense of self in relation to the external world), consciousness, analogy-making, artistic creation, literary translation, and discovery in mathematics and physics. Hofstadter's book "Gödel, Escher, Bach: An Eternal Golden Braid", first published in 1979, won both the Pulitzer Prize for general non-fiction
Document 10: Noam Chomsky: Avram Noam Chomsky ( ; born December 7, 1928) is an American linguist, philosopher, cognitive scientist, historian, social critic, and political activist. Sometimes described as "the father of modern linguistics," Chomsky is also a major figure in analytic philosophy and one of the founders of the field of cognitive science. He is the author of over 100 books on topics such as linguistics, war, politics, and mass media. Ideologically, he aligns with anarcho-syndicalism and libertarian socialism.

Document 11: Peri Tarr: Peri Tarr received her BS in Zoology from the University of Massachusetts Amherst in 1986, and her MS and PhD in Computer Science from the University of Massachusetts Amherst (1992 and 1996, respectively). Between her BS and MS/PhD, she worked full-time at the University of Massachusetts Physical Plant, attempting to introduce an automated system to help with the Plant's operations. After receiving her PhD, she joined the IBM Thomas J. Watson Research Center as a Research Staff Member in 1996, where she worked on and led various projects relating to issues of software composition, morphogenic software, and aspect-oriented software development.
Document 12: Copycat (software): Copycat is a model of analogy making and human cognition based on the concept of the parallel terraced scan, developed in 1988 by Douglas Hofstadter, Melanie Mitchell, and others at the Center for Research on Concepts and Cognition, Indiana University Bloomington. The original Copycat was written in Common Lisp and is bitrotten (as it relies on now-outdated graphics libraries); however, Java and Python ports exist.
Document 13: Parallel terraced scan: The parallel terraced scan is a multi-agent based search technique that is basic to cognitive architectures, such as Copycat, Letter-string, the Examiner, Tabletop, and others. It was developed by John Rehling and Douglas Hofstadter at the Center for Research on Concepts and Cognition at Indiana University, Bloomington.
Document 14: Jorge Luis Borges and mathematics: Jorge Luis Borges and mathematics concerns several modern mathematical concepts found in certain essays and short stories of Argentinian author Jorge Luis Borges (1899-1986), including concepts such as set theory, recursion, chaos theory, and infinite sequences, although Borges' strongest links to mathematics are through Georg Cantor's theory of infinite sets, outlined in "The Doctrine of Cycles" ("La doctrina de los ciclos"). Some of Borges' most popular works such as "The Library of Babel" ("La Biblioteca de Babel"), "The Garden of Forking Paths" ("El Jardín de Senderos que se Bifurcan"), "The Aleph" ("El Aleph"), an allusion to Cantor's use of the Hebrew letter aleph (formula_1) to denote cardinality of transfinite sets. and "The Approach to Al-Mu'tasim" ("El acercamiento a Almotásim") illustrate his use of mathematics.
