In this chapter, we present the findings of the National Assistive Technology Research Institute (NATRI). The institute was funded in October 2000 as a cooperative agreement with the U.S. Department of Education, Office of Special Education Programs to take a comprehensive look at the factors related to the planning, development, implementation, and evaluation of assistive technology (AT) services in schools. We present the data from seven research areas: (1) the status of AT use in schools, (2) policies and procedures in the development and delivery of AT services, (3) AT decision-making by IEP teams, (4) integration of AT use in learning environments (facilitate instruction, access to curriculum), (5) effects of AT use on academic, social, functional performance of students, (6) training and technical support needed by persons implementing AT, and (7) the extent to which institutions of higher education (IHEs) were developing AT knowledge and skills. In each area we summarize the lessons learned as a result of the research to assist policy-makers, researchers, and practitioners in improving AT services and delivery systems.

Purpose – This essay attempts to answer the question, “What distinguishes inter-human influence from other forms of influence?”

Design/methodology/approach – Specifying the micro-foundations of social structures in terms of communicative inferences necessitates a revision of the concept of social structures (and institutions) as distributed, and hence, uncertain, structures of expectation. Institutional realities are generated in linguistic interaction through the indirect communication of generic references. The generalizing function of language – in particular, abstraction and memory – coupled with its reflexive function, to turn references into things, are sufficient to generate both social structures and institutions as collective inferences.

Findings – Social relations are fundamentally communicative relations. The communicative relation is triadic, implying an enunciator, an audience, and some referential content. Through linguistic communication, humans are capable of communicating locally with others about others nonlocally. Institutions exist only as expectations concerning the expectations of others. These expectations, however, are not only in the mind, and they are not exclusively psychological entities. Linguistically, these expectations appear as the reported statement within the reporting statement, that is, they are constituted through indirect discourse.

Research limitations/implications – An important implication for current sociological theory is that, from the point of view of a sociology defined as communication about communication from within communication, institutional realities should not be reified as existing naturalistically or objectively above or behind the communications through which they are instantiated.

Originality value – This approach, then, is decidedly anti-“realist.” The goal of such research is to examine the inadequacy of nonreflexive models of social order. Accounts of how sets of social relationships emerge will remain inadequate if they do not reflect upon the cognitive and communicative processes which make possible the consideration of such structures.
