[Abstract]Are universals (kinds) something over and above the things (their instances) of which they are kinds? Does the universe come already packaged into kinds of thing, or are the universals which the human and animal mind distinguishes simply the product of the mind's classificatory activity? Whether universals are mind-independent or mind-dependent, are the concepts human beings and other living organisms have of them innate or are they generated wholly or in part by some kind of learning process. In either case, what assurance do we have that our conceptual scheme does not seriously misrepresent the way things are, as Kant puts it, "in themselves." While the tides of philosophical fashion have flowed backwards and forwards between the poles of this debate ever since the time of Plato and Aristotle, it is argued that there is now some reason to think that the current tide which appears to be moving away from platonism and nativism and back towards conceptualism and empiricism may be taking us towards a permanent scientifically-based resolution of the problem. This solution, if that is what it is, gives due weight to both innate factors and learning at the biological level and to social construction at the level of human linguistic communication. It sees Darwin's principle of variation and natural selection as operating as much in the ontogenetic development of our conceptual scheme as in its phylogeny, and as providing the assurance we need that, in B.F.Skinner's words, it takes "account of the natural lines of fracture along which behavior and environment actually break." (Skinner 1938 p.33).

Place, U. T. (1992j). Towards a reconciliation between the associationist and radical behaviorist traditions in the experimental analysis of behavior. [Unpublished paper. Presented under the title 'The three term contingency as a link between the associationist and radical behaviorist traditions in the experimental analysis of behavior' as Invited Address to the First International Congress on Behaviorism and the Sciences of Behavior, Guadalajara, Mexico, 6th October 1992].
[Abstract]It is an implication of the Law of Non-Contradiction that two incompatible descriptions of the same class of phenomena cannot both be true. This suggests that the future for radical behaviorism must lie in achieving a reconciliation with other disciplines and approaches studying the same or closely related phenomena. The approach known as "associative learning theory" shares a common data basis with radical behaviorism in the area of the experimental analysis of animal behavior. It is separated from radical behaviorism by a different view of the nature of what is learned. According to the radical behaviorist, under certain antecedent conditions (discriminative stimulus + establishing condition) an organism learns to emit a response. According to associative learning theory what is learned is an association between a pair of consecutive stimulus events. When presented with the first member of the pair, the organism learns to "predict" or "expect" the second member of the pair. Until recently, the principal application of this principle was Rescorla and Wagner's (1972) analysis of  Pavlovian (respondent) conditioning. More recently, Adams and Dickinson's (1981) reinforcer-devaluation experiment has led associationists to pay more attention to instrumental (operant) learning. It has also opened up an interesting divergence of views between Dickinson (1988; Heyes and Dickinson, 1991; Dickinson & Balleine, forthcoming) who takes it as evidence of a discontinuity between respondent conditioning, which he interprets in terms of the establishment of mechanical associations, and operant learning which he interprets in terms of the ‘beliefs’ and ‘desires’ of philosophical action theory, and Rescorla (1991) who uses it as evidence for an interpretation of operant learning based on the same principles of stimulus-stimulus association invoked by Rescorla and Wagner to account for respondent conditioning. Standing in the way of a reconciliation between radical behaviorism and associative learning theory are the misgivings of the former about the use made by the latter of ‘mentalistic’ concepts, such as ‘expect,’ ‘anticipate,’ and ‘predict.’ These misgivings may be allayed if attention is paid to the results of applying to such concepts the technique, known as ‘conceptual analysis,’ developed by Wittgenstein (1953; 1958) and the philosophers of the Oxford ‘ordinary language’ school. A recent application of this technique to the linguistic phenomenon known variously as ‘intentionality’ or ‘intensionality’ shows that it consists of two distinct varieties of ‘referential anomaly’ which ‘infect’ the grammatical objects of certain verbs. In one case, the grammatical object is used to indicate a range of possible events any one of which, if it were to occur, would constitute a manifestation or satisfaction of a disposition. In the other case, the grammatical object functions as a quotation of what the agent either has said or might be expected to say or have said. Referential anomaly of the dispositional kind is both unavoidable and benign, but the use of quotations to characterize behavioral dispositions is acceptable for scientific purposes only in those cases where the behavior in question is in fact subject to linguistic control. Since the grammatical object of the verbs ‘know,’ ‘believe’ and ‘think,’ as they occur in belief/desire explanations, takes the form of an embedded indicative sentence in oratio obliqua or indirect reported speech, Dickinson's explanation of instrumental/operant learning in animals involves the scientifically unacceptable metaphor of linguistic initiation and control. Rescorla's theory, on the other hand, requires nothing more than that the organism learn to ‘expect’ or ‘anticipate’ an event (the outcome), given the combination of an antecedent discriminative stimulus and the stimulus constituted by the incipient emission of the response which it evokes. In this case the anomaly of reference in the noun phrase which occurs as the grammatical object of the verb reflects its use as a device for indicating a range of possible outcomes any one of which, if it occurred, would fulfill and confirm the expectation which it specifies.

Place, U. T. (1993i). Following 'the natural lines of fracture': Concept formation in neural networks [Conference presentation, presented at the Symposium on Associationism, Behaviour Analysis and Connectionism, held at the Annual Conference of the Experimental Analysis of Behaviour Group, University College, London 31st March 1993].
[Abstract]It is an implication of Darwin's theory of evolution by variation and natural selection that the survival and reproduction of complex free-moving living organisms, animals in other words, depends on their ability to change the spatial relations between themselves and other objects, including other organisms of the same and of different species, and so bring about the conditions necessary for that survival and reproduction. In order to do that the organism requires a system - its nervous system - whose function is to match the output to the current stimulus input on the one hand and the organism's current state of deprivation with respect to conditions required for its survival and successful reproduction on the other. Matching behaviour to the conditions required for survival and reproduction is the function of the motivational/emotional part of the system. Matching behaviour to current stimulus input is the function of the sensory/cognitive part of the system. The sensory/cognitive system cannot perform its function successfully without the ability to group inputs together in such a way that every actual and possible member of the class or category so formed is a reliable indicator of the presence of an environmental situation in which a particular behavioural strategy or set of such strategies is going to succeed. In other words the survival and reproduction of an organism of this kind depends crucially on its having a conceptual scheme, a conceptual scheme moreover, which reliably predicts the actual behaviour-consequence relations operating in the organism's environment. Although verbs such as ‘classifying’, ‘categorizing’ and ‘conceptualizing’ are not to be found in Skinner's writings, there is an important passage in The Behavior of Organisms (Skinner 1938) where he addresses the issue which others talk about when they use such terms. Thus in Chapter One, after outlining his "System of Behavior", he goes on to say The preceding system is based upon the assumption that both behavior and environment may be broken into parts which retain their identity throughout an experiment and undergo orderly changes. If this assumption were not in some sense justified, a science of behavior would be impossible. But the analysis of behavior is not an act of arbitrary sub-dividing.  We cannot define the concepts of stimulus and response quite as simply as ‘parts of behavior and environment’ without taking account of the natural lines of fracture along which behavior and environment actually break. (Skinner 1938 p.33). What Skinner has primarily in mind in this passage is the way the scientist's concepts need to be shaped into conformity with what he calls "the natural lines of fracture." But on the Darwinian argument the same must be true of the stimulus classes within which any living organism's behaviour generalises and between which it discriminates. It is argued that studying the properties of artificially constructed neural networks helps us to understand how the brain develops patterns of generalisation and discrimination which do indeed "follow the natural lines of fracture along which behavior and environment actually break." Attention is drawn to the role of the ‘hidden layer’ in responding to resemblances of pattern, to the role of re-entrant/recurrent and reverberatory circuits in establishing expectations on the basis of consecutive stimulus patterns, and to the role of error-correction in bringing stimulus classes into line with the contingencies experienced during learning.

Unsupervised and supervised learning in neural networks [Unpublished paper presented at the Annual Conference of the Experimental Analysis of Behaviour Group, University College, London, 30th March 1992, and at the Inter-Univerrsity Centre Conference on 'Connectionism and the Philosophy of Mind,' Park Hotel, Bled, Slovenia, 10th June 1993].
[Abstract]The paper examines the relationship between three distinctions, two drawn from the current literature on learning in connectionist networks and one from the animal learning literature: 1. the distinction drawn by connectionists between 'unsupervised' and 'supervised' learning, 2. the distinction also drawn by connectionists between the Hebbian and 'delta' or error-correction learning rules, and 3. the distinction drawn within traditional learning theory between classical or respondent conditioning on the one hand and instrumental or operant learning on the other. It is argued that, despite differences in the way error-correction is applied in the two cases, the distinction between unsupervised and supervised learning corresponds closely to that between classical and instrumental learning. But, whereas unsupervised learning is usually implemented in artificial networks by a version of the Hebbian rule and supervised learning by the 'delta' rule, recent and not so recent work in animal learning suggests that, given plausible assumptions about the arrangement of the network, a version of the Hebbian rule can account for both types of learning.

A selectionist approach to the problem of universals [Conference presentation, presented in the session 'Conceptual and Philosophical Issues in Behavior Analysis' of the 22nd Annual Convention of the Association for Behavior Analysis, San Francisco, May 27th 1996]. Association for Behavior Analysis.
[Abstract]As it is discussed by philosophers, the problem of universals has two aspects: an ontological aspect and an epistemological aspect. Views on the ontological aspect divide between "realism" which holds that universals are abstract objects, distinct from their instances, with which the organism's concepts must line up if it is to survive and reproduce, and "constructivism" which holds that the organism's concepts are the only universals there are. Views on the epistemological issue divide between "nativism" which holds that concepts are innate, and "empiricism" which holds that they are learned. Most realists are nativists. Most constructivists are empiricists. Selectionist considerations suggest a middle position between these extremes: (1) There are no universals in the absence of a classifying organism (constructivism). (2) There is a significant innate contribution to the organism's system of concepts (nativism). (3) The fine tuning which brings the organism's concepts into line with what Skinner (1938) calls "the natural lines of fracture along which environment and behavior actually break" is a matter of contingency-shaped discrimination learning (empiricism). (4) There are objective constraints which ensure that the concepts so formed line up with "real" similarities and differences between objects, events and states of affairs in the organism's interactions with the environment (realism).

[Abstract]The thesis of this paper is that behaviourism is the only adequate scientific foundation for the disciplines of psychology, linguistics and linguistic philosophy.  Behaviourism in psychology is presented as a convergence of six principles: (1) behaviour as the subject matter of psychology, (2) the objectivity principle, (3) the rejection of mentalistic explanation, (4) the three-term contingency, (5) the distinction between discriminative stimuli and establishing conditions, and (6) learning theory. Behaviourism in linguistics and linguistic philosophy is seen as resting on ten principles: (1) language as communication in the service of technology, (2) language and thought, (3) the sentence as the functional unit of linguistic communication, (4) novel sentence-construction, (5) novel sentences and the representation of unfamiliar contingencies, (6) sentence-construction and the win-shift/fail-stay contingency, (7) the picture theory of the meaning of sentences, (8) the associative learning of word and phrase meaning, (9) lexical words, syntactic words and Bickerton's "proto-language", (10) mutations and the facilitation of language learning.

[Abstract]Cowey & Stoerig's (1995) demonstration that the phenomenon of blindsight applies to monkeys with striate cortical lesions in the same way as it does to humans with similar lesions makes it plausible to argue that the behaviour of mammals and probably that of other vertebrates is controlled by two distinct but closely interdependent and interacting systems in the brain which I shall refer to respectively as 'consciousness' and the 'sub-conscious automatic pilot or "zombie" within'. On this hypothesis, consciousness has three functions, (a) that of categorizing any input that is problematic in that it is either unexpected or significant relative to the individual's current or perennial motivational concerns, (b) that of selecting a response appropriate both to the presence of a thing of that kind and to the individual's motivational concerns with respect to it, and (c) that of monitoring the execution of that response. Conscious/phenomenal experience, on this view, is the first stage in the process whereby problematic inputs are processed by consciousness. Its function is to modify the figure-ground relations within the central representation of a problematic input until an adequate categorization is selected. The sub-conscious automatic pilot or “zombie-within” has two functions (a) that of continuously scanning the total current input and alerting consciousness to any input it identifies as problematic, (b) that of protecting consciousness from overload either by ignoring those non-problematic inputs which require no response or by responding appropriately but automatically to those for which there already exists a well practised skill or other “instinctive” response pattern.
