I shall argue in this chapter that the discussion of nonreductive materialism has been conducted under the shadow of an ambiguity in the sense of reductive. One sense is specific to the philosophy of mind, and here the reductive tradition is marked by the attempt to give an account of the mind in behavioral or functional terms, without remainder. The other sense derives from the philosophy of science, and it concerns the possibility of giving some kind of systematic account of “higher” sciences in terms of “lower” ones, and, ultimately, in terms of physics. I shall argue that failure to distinguish these senses in Davidson's “Mental Events” has led to serious confusions in the discussion of “nonreductive materialism” and in the attendant notion of ‘supervenience.’ Davidson has clarified the confusion in “Mental Causes”, but in a way that makes his original contribution much less interesting than it had seemed to be. In the course of the discussion, I hope to clarify the various senses in which theories, properties, and predicates can be ‘reduced’ or ‘emergent.’
Story 1. In order to vindicate a materialist theory of the mind it is necessary to show how something that is a purely physical object can satisfy psychological predicates. Those features of the mind which seem to be, prima facie, incompatible with this physicalism – such as consciousness and the intentionality of thought – must, therefore, be explained in a way that purges them of their apparently Cartesian elements, which would be incompatible with materialism.
The word physicalism, when introduced into philosophical conversation by Neurath and Carnap, seemed theirs to define, much as a century earlier the word positivism had been Comte's to define. Not everyone is so lucky as to introduce a label by which they will later become known, and such was the lot of Locke who has been tossed with Hobbes and Hume into the catchall bin of Empiricism. Whether original with Locke or presaged in Leviathan, the idea that Ideas were all the mind could contemplate seems distinctive enough to deserve its own ‘ism.’ In any event, the marriage of Locke's internal Empiricism with Comte's cold Positivism produced the uneasy union that the Vienna Circle styled ‘physicalism,’ but that the world has since come to call by turns ‘Logical Positivism’ and ‘Logical Empiricism.’ That a philosophical position could be defined by conjoining two seemingly mismatched themes would itself be of at least historical interest. But it gains a more topical interest if we could show how antiphysicalist theses more recently bandied about were born of the same unhappy union. To that end we will begin in the middle.
Consistent with their antimetaphysical approach to philosophy, Neurath and Carnap cast their original definition of physicalism in linguistic terms. Roughly, physicalism was the name they gave to the thesis that every meaningful sentence, whether true or false, could be translated into physical language. Although both thought the thesis obviously true, neither thought it knowable a priori.
It is a commonplace that much of contemporary metaphysics is deeply bound up with the metaphysical modalities: metaphysical possibility and necessity. To take one central instance, the mind-body problem, in its most familiar contemporary form, appears as a problem about property identities, and it is hard to imagine discussing any issue about property identity without calling on the idea of metaphysical possibility. If we want to ask whether the property of being conscious, or being in pain, or having this sort of pain S, is identical with some physical or functional property P – say, the property of having such-and-such neurons firing in such-and-such a way – we typically begin by asking whether I could have had these neurons firing in this particular way, without experiencing S. And the could here is the could of metaphysical possibility.
As we all know, these questions about what could be the case – metaphysically could – are far from easy to answer. There are, it seems to me, two features of the notion of metaphysical possibility that combine to make them hard to settle, either negatively or positively. What makes them hard to settle negatively is that because metaphysical possibility is supposed to be a kind of possibility distinct from physical possibility, styles of argument that work very well to show that various describable situations are not physically possible do not carry over to show that the same situations are not metaphysically possible. Most of us would agree that the standard correlations between brain and pain already give us excellent reasons for believing that it is not physically possible for there to be a perfect neurological duplicate of me who feels no pain at the dentist's.
This chapter is an attempt to understand the content of and motivation for a popular form of physicalism, which I call nonreductive physicalism. Nonreductive physicalism claims that although the mind is physical (in some sense), mental properties are nonetheless not identical to (or reducible to) physical properties. This suggests that mental properties are, in earlier terminology, emergent properties of physical entities. Yet many nonreductive physicalists have denied this. In what follows, I examine their denial, and I argue that on a plausible understanding of what emergent means, the denial is indefensible: nonreductive physicalism is committed to mental properties being emergent properties. It follows that the problems for emergentism – especially the problems of mental causation – are also problems for nonreductive physicalism, and they are problems for the same reason.
The structure of the chapter is as follows. In the first section, I outline what I take to be essential to nonreductive physicalism. In the second section I attempt to clarify what is meant by emergent, and I argue that the notion of emergence is best understood in terms of the idea of emergent properties having causal powers that are independent of the causal powers of the objects from which they emerge. This idea, ‘downward causation,’ is examined in the third section. In the final section I draw the lessons of this discussion for the contemporary debate on the mind-body problem.
This paper examines the provision of networked CALL services at the Faculty of Modern and Medieval Languages at the University of Cambridge. It argues that in such a context a broad, inclusive approach to networking – one which avoids any over-strict commitment to a single method or paradigm of network delivery, but makes the most of whatever is available – is often the most appropriate. This eclectic approach helps preserve the best of what has been created in the past while keeping up with everything technological advances offer, and respects the wide-ranging and widely-differing views and approaches of Faculty teaching staff. The aim of the MML Network Service is therefore to present a wide range of disparate resources in a single, coherent framework. While welcoming the many advantages the use of the World Wide Web brings, the article stresses that in a broad infrastructure both older programs which have proved their worth and newer, highly-developed programs which have come after them need not be lost while the functionality of the Web is still developing. It also lays out in general terms some technical suggestions for those seeking ideas on the implementation of networking strategies in a Windows-based local area or university-wide network, partly with a view to reinforcing the credentials for CALL and humanities computing generally to be afforded high-quality computing infrastructure both in the present and with whatever technological advances bring in the future.
This paper examines the role of checklists as a device for evaluating CALL courseware. After defining checklists, it examines the reasons why courseware is difficult to evaluate compared to other educational materials. It then covers in detail the main objections to the use of checklists for courseware evaluation; articles in the CAL literature from the 1980s through the 1990s have complained that checklists are inaccurate, cannot deal with educational issues, lack objectivity and reliability, are biased, etc. The present paper then examines these claims one by one, finding either that the criticism is unjustified or that it applies equally to any form of courseware evaluation. The paper concludes with speculations, drawn from postmodern literary theory, as to why the checklist has been the target of so many unsubstantial attacks.
This paper presents a proposed initial implementation for the DISSEMINATE concept and architecture first presented in 1998 at WorldCALL. Via an explanation of the explosion of the acronym, the article summarises the key points made in the initial article published by Swets and Zeitlinger in a volume edited by Chambers and Davies (Delcloque, 2001) where the project was described as the “implementation in the digital domain of the ring-binder philosophy”. It explains the slight changes and refinements brought to the general approach since its inception, presents briefly the results of a survey designed to examine authoring requirements and authors’ attitudes to authoring tools, summarises evidence of partially similar approaches taken by other developments and outlines the possible paths to the implementation of the project. It discusses some early proposals relating to the Macro Infrastructure and presents a Micro Module example. The article concludes with an explanation of the proposed provisional distribution structure, including commercial considerations, which, in the authors’ view, cannot be separated from the theoretical and practical questions which the concept poses. The conclusion also suggests that the principles of DISSEMINATE, whether or not resulting in a product, could nevertheless influence present and future digital learning authors.
This paper discusses the findings of two empirical studies which investigated how students of English used two English learners’ dictionaries on CD-ROM. The outcome of these studies will indicate in what way such dictionaries can serve as reference and language learning tools. It is argued that an English learner’s dictionary on CD-ROM could be much more than an ‘ordinary’ reference work because it includes facilities that are not available in book form, such as audio and visual elements, exercises and games. The studies suggest, however, that a number of changes in content and design will have to be made in order to make such dictionaries more effective and beneficial to their users. Learners, on the other hand, may need to acquire special skills in order to benefit from all the information an English learner’s dictionary on CD-ROM contains.
The reports of the demise of the CD-ROM have proved to be a little premature, if one judges by the contents of this issue of ReCALL. Whilst it is true that there is a strong emphasis in the articles by Huw Jarvis, Julie Belz and Lina Lee on the opportunities offered by network-based learning – and the trend towards such a focus is inevitable – it remains the case that the CD-ROM is still capable of rich and significant exploitation, as shown in the articles by Gunther Kaltenboeck and Birgit Winkler. Gavin Burnage argues for a ‘broad inclusive approach to networking’ which declines to abandon the old data-carriers, whether floppy-based DOS programs or CD-ROMs and argues for the pragmatic integration of a wide range of disparate resources into a single, coherent framework. DISSEMINATE, the macro-structure articulated here by Philippe Delcloque and Alexandre Bramoullé, is a concept with a similar integrative ambition but from an authoring perspective.
This paper describes an experiment in which an attempt was made to show that Japanese Computer Assisted Language Learning (JCALL) with Animated Graphical Annotation (AGA) is more effective and useful in assisting learners to acquire Japanese language listening skills compared to JCALL without AGA. The independent variable in the experiment is AGA. The principal research question addressed was, “Does the AGA used in the JCALL contribute to the students’ overall pronunciation and listening performances in elementary Japanese language courses by looking into its AKUSENTO (symbol missing), SEION (symbol missing) and DAKUON (symbol missing) and TANON, CHOUON & SOKUON (symbol missing)?”The experiment was conducted in Malaysia last summer. One hundred and twelve students (25 male and 87 female) who were enrolled in Japanese language courses participated in this study. The students were randomly divided into two groups and the pre-test/post-test approach was used in this study. The results of the research showed AGA’s effectiveness in assisting the students to improve their listening skills. However, AGA appeared to be less effective in helping the students to improve their pronunciation skills.
Network-based language teaching (NBLT) involves the application of global or local communication networks within foreign and second language education (Warschauer and Kern, 2000). In telecollaboration, a type of NBLT, distally located language learners use internet communication tools to support dialogue, debate, collaborative research and social interaction for the purposes of language development and cultural awareness (e.g. Kinginger et al., 1999). To date, the research on NBLT has been limited, focusing primarily on pedagogical implementations of technology and linguistic features of online communication. In particular, researchers have not robustly explored social and institutional dimensions of telecollaboration (Chapelle, 2000:217) nor have they adequately investigated the pervasive assumption that telecollaborative interaction will necessarily and unproblematically afford language learning (e.g. Kramsch and Thorne, to appear). Drawing on social realism (Layder, 1993), a sociological theory which emphasizes the inter-relationship between structure, i.e. society and institution, and agency, i.e. situated activity and psycho-biography, in researching and explaining social action, I present a sociocultural account of German-American telecollaboration. In particular, I explore the meanings that the macro features of (1) language valuation (Hilgendorf, 1996); (2) membership in electronic discourse communities (Gee, 1999); and (3) culturally determined classroom scripts (Hatch, 1992) may have for the differential functionality of virtual group work in this partnership. Differences in group functionality are reflected at the micro-interactional level in terms of (1) frequency and length of correspondence; (2) patterns of discursive behavior such as question-answer pairs; and (3) opportunities for assisted L2 performance and negotiation of meaning. Ethnographic data (e.g. interviews, electronic and classroom discourse, surveys and participant observations) on individual psycho-biographies are interwoven with macro-level descriptions and statistics to paint a rich picture of learner behavior in intercultural telecollaboration. This project is funded by a United States Department of Education International Research and Studies Program Grant (CFDA No.: 84.017A). The author is a research associate for the German component.
Building on the experience of developing a CD-ROM for English intonation practice, this article explores some advantages and limitations of this medium for the teaching of suprasegmentals. Despite their undeniable potential for foreign language learning, computers prove to be rather limited in their feedback to pronunciation, especially in terms of error identification and correction, which calls into question one of their very strengths, viz. that of teacher-independent learning. As a possible solution to this dilemma, the present paper proposes to build into the design of a CD-ROM for intonation teaching the concept of learner autonomy, i.e. transferring to an increased degree responsibility for the learning process from the teacher (computer) to the learner. Drawing on the discussion of autonomy by, e.g. Broady & Kenning (1996) and Little (1999), it is demonstrated how incorporating a metacognitive level (by offering the learner the choice to access intonation in different ways) and a metalinguistic level helps to make the CD-ROM users more autonomous in their learning and equip them with the necessary tools for self-assessment and self-monitoring, which in turn can make up for the lack of computerised diagnostic feedback.
The International Conference Eurocall 2001 was held from 29 August to 1 September 2001 at the Catholic University of Nijmegen, Netherlands. The conference attracted more than 350 participants from all over the world.
This paper begins by documenting general usage of the Internet as a tool for delivery of English for Academic Purposes (EAP) courses. It then goes on to illustrate how a number of specific internet-based classroom activities might be integrated onto EAP courses in order to equip non-native speakers with the main skills that they are likely to need when following an academic course at a British university.
To transform pedagogically sound classroom tasks into effective CALL-ware, it is advantageous to have an approach that takes into account the general principles applicable to all human computer interaction (HCI). This paper outlines an attempt at such an approach. Teacher-designed, pedagogically sound software often fails in terms of usability, while highly usable, professionally made software is often based on ideas that are not in accord with those of a particular curriculum or teacher.The approach outlined below may assist in the process of transforming pedagogic materials and practices already successfully used in the classroom into easily usable software.
Online interactive exchange offers learners many opportunities to use the target language to negotiate both meaning and form in a social context that is crucial for second language acquisition (SLA). This paper discusses the interaction between non-native speakers (NNSs) and the types of communication strategies employed during the online communication. A total of forty students participated in online discussions using a private chatroom. Data from this study suggest that interactive strategies facilitate comprehension of input and output. The results show that regardless of proficiency level, students used a variety of communication strategies. However, students tended to use more comprehension checks, clarification checks, requests and self-repairs to negotiate with each other. The quick interactions taking place in cyberspace impeded students from producing correct and coherent discourse, especially during the learner-learner interaction. Pedagogically, students need to be advised of the need to write correctly to maintain a balance between function, content, and accuracy. One of the corrective techniques is to make studentsre-examine and revise their exchanges with guided instruction. The current study focused on online interaction among NNSs. To claim the effectiveness of online interaction in SLA with certainty, future studies on online negotiation must include both NNSs and native speakers.
This contribution extends the notionsof roots and periodicity to strings of transfinitelengths. It shows that given atransfinite string, either it possesses a unique root or the set of itsroots are equivalent in a strong way.
