Ontologies, Mental Disorders and Prototypes

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field do not allow for the representation of concepts in terms of typical traits. However, the need of representing concepts in terms of typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific mental disorders. On this respect, we favor a hybrid approach to the representation of psychiatric concepts, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual spaces

Stopping at Stoppard: Decompositional Linguistic Models and Deconstructionism in Stoppard’s The Real Inspector Hound and Arcadia

This thesis will develop connections between the decomposition of binaries in the cognitive linguistic model of prototype theory and the deconstructionism of binaries in the literary critical theory of deconstructionism, focusing on Tom Stoppard’s The Real Inspector Hound to show the operation of the theory in literature and using on Stoppard’s Arcadia as an example of an application of prototype theory as a critical lens. Prototype theory is a linguistically and psychologically-based theory of categorization which rejects the definition of categorization found in classical theory. Deconstructionism is a reaction to and a partial rejection of structuralism, and teaches that language deconstructs itself through the breakdown of binaries and through a focus on the assumptions made within a text. Both these theories break down the binary conceptualizations in language set up by former theories, while avoiding anti-order by a continued use of binaries in different ways or by a re-ordering into new binaries or into multiplicities. Stoppard, who is often defined as a poststructuralist writer, has often been viewed through the lens of deconstructionism critical theory.1 However, his texts have not before been viewed through the lens of the similar transdisciplinary theory of prototypical categorizations. This thesis will use The Real Inspector Hound as an example of binary breakdown through the text’s overt discussion of binaries, and Arcadia as an example of prototype theory textual analysis through a discussion of the prototypicality of the different kinds of love portrayed in this text

An empirical revision of the definition of science fiction: it is all in the techne...

Researchers employ science fiction and fantasy in public engagement, advocacy, and education as significant sources of insights to identify public interests, inspire public policy, and influence future science. These uses of science fiction as a source that is expected to reflect public interests are undermined if the examples employed by researchers are interpreted differently by the intended audience or beneficiaries of research. We surveyed the public to identify their definitions and discovered a categorization based on clearly defined features. These align with some academic theories but differ from postmodern approaches as the analysis suggests science fiction can be defined categorically. The empirical survey data are consistent and demonstrate an unmistakable distinction between popular definitions of science fiction and fantasy. Our theoretical analysis implies some definitions may be confused by evaluating secondary "fuzzy" characteristics as if they were fundamental features of the genre. We suggest Wittgenstein's family resemblances, between subjects associated with the genre at any specific time, should be interpreted as an ephemeral grouping validated by correlation with enduring core features, rather than definitive. On the basis of the common themes identified from the survey responses and a critique of existing genre models, we suggest the classical concept of techne may best describe the empirical essence of science fiction. Researchers intending to employ science fiction for applications that have an influence in the public realm may wish to consider this when designing their research

Mind-wandering as a natural kind: A family-resemblances view

As empirical research on mind-wandering accelerates, we draw attention to an emerging trend in how mind-wandering is conceptualized. Previously articulated definitions of mind-wandering differ from each other in important ways, yet they also maintain overlapping characteristics. This conceptual structure suggests that mind-wandering is best considered from a family-resemblances perspective, which entails treating it as a graded, heterogeneous construct and clearly measuring and describing the specific aspect(s) of mind-wandering that researchers are investigating. We believe that adopting this family-resemblances approach will increase conceptual and methodological connections among related phenomena in the mind-wandering family and encourage a more nuanced and precise understanding of the many varieties of mind-wandering

Ontologies, Disorders and Prototypes

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field (such as, in the first place, the Web Ontology Language - OWL) do not allow for the representation of concepts in terms of typical traits. The need of representing concepts in terms of typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific disorders. We favour a hybrid approach to concept representation, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual space. As a preliminary step to apply our proposal to mental disorder concepts, we started to develop an OWL ontology of the schizophrenia spectrum, which is as close as possible to the DSM-5 descriptions

A Theory of Genre Formation in the Twentieth Century

In his article "A Theory of Genre Formation in the Twentieth Century" Michael Rodgers explores the relationship between Vladimir Nabokov's Invitation to a Beheading and magical realism in order to theorize about genre formation in the twentieth century. Rodgers argues not only that specific twentieth-century narrative forms are bound intrinsically with literary realism and socio-political conditions, but also that these factors can produce formal commonalities

The benefits of prototypes: The case of medical concepts

In the present paper, we shall discuss the notion of prototype and show its benefits. First, we shall argue that the prototypes of common-sense concepts are necessary for making prompt and reliable categorisations and inferences. However, the features constituting the prototype of a particular concept are neither necessary nor sufficient conditions for determining category membership; in this sense, the prototype might lead to conclusions regarded as wrong from a theoretical perspective. That being said, the prototype remains essential to handling most ordinary situations and helps us to perform important cognitive tasks. To exemplify this point, we shall focus on disease concepts. Our analysis concludes that the prototypical conception of disease is needed to make important inferences from a practical and clinical point of view. Moreover, it can still be compatible with a classical definition of disease, given in terms of necessary and sufficient conditions. In the first section, we shall compare the notion of stereotype, as it has been introduced in philosophy of language by Hilary Putnam, with the notion of prototype, as it has been developed in the cognitive sciences. In the second section, we shall discuss the general role of prototypical information in cognition and stress its centrality. In the third section, we shall apply our previous discussion to the specific case of medical concepts, before briefly summarising our conclusions in section four

Ludwig Wittgenstein’s Legacy to Cognitive Psychology: Concepts as Participatory

Ludwig Wittgenstein (1889–1951) is regarded as one of the most influential and eminent philosophers of the twentieth century. In both his early and later work, he is a key figure in the development of analytical philosophy: he wants us to see that natural language use is pivotal to understanding the nature of the mind. However, his later work, specifically with regard to the Philosophical Investigations (1953) [henceforth referred to as the Investigations], where concepts are a participating part of the context, makes him a key figure in contemporary cognitive psychology. While Wittgenstein’s interest in psychology began between 1934-1936 when he lectured on private experience and sense data, his contributions to the field of psychology continued up until his death in 1951. Unknown to Wittgenstein at the time, his remarks on philosophical psychology would have an enormous influence on both the psychology and philosophy disciplines
