Note on the integration of prototype theory and fuzzy-set theory

Many criticisms of prototype theory and/or fuzzy-set theory are based on the assumption that category representativeness (or typicality) is identical with fuzzy membership. These criticisms also assume that conceptual combination and logical rules (all in the Aristotelian sense) are the appropriate criteria for the adequacy of the above “fuzzy typicality”. The present paper discusses these assumptions following the line of their most explicit and most influential expression by Osheron and Smith (1981). Several arguments are made against the above identification, the most important being that representativeness in prototype theory is exclusively based on element-to-element similarity while fuzzy membership is inherently an element-to-category relationship. Also the above criteria for adequacy are criticized from the viewpoint of both prototype theory and fuzzy-set theory as well as from that of both conceptual and logical combination, and also from that of integration.     

道德层次论与人生境界说

不同的人有不同的人生境界,同一个体,其在不同阶段,由于觉解程度不同,所呈现的人生境界也不尽一致。对处于不同人生境界的个体而言,其对道德行为的践行则有所不同,由此出现道德冷漠、道德顾虑、道德恐惧以及道德自由诸种道德行为。不同道德行为,多是一种偶在性表现,既不是个体一成不变的定行,亦非某一群体集体行为的表征。每一种道德行为的出现,都有其相应的内因外缘,剖析诸类非正常道德行为出现的缘由,以期提出对治之方,这是学者的使命,亦是社会之所寄。     

The molarity of molecular theory and the molecularity of molar theory.

Dinsmoor (2001) rejects shock-frequency reduction as a reinforcer for avoidance behavior, and considers this to be an invalidation of so-called molar avoidance theory. This is a narrow view of operant avoidance theory, for which shock-frequency reduction is by no means the only reinforcer.     

Linear theory, dimensional theory, and the face-inversion effect

We contrast 2 theories within whose context problems are conceptualized and data interpreted. By traditional linear theory, a dependent variable is the sum of main-effect and interaction terms. By dimensional theory, independent variables yield values on internal dimensions that in turn determine performance. We frame our arguments within an investigation of the face-inversion effect--the greater processing disadvantage of inverting faces compared with non-faces. We report data from 3 simulations and 3 experiments wherein faces or non-faces are studied upright or inverted in a recognition procedure. The simulations demonstrate that (a) critical conclusions depend on which theory is used to interpret data and (b) dimensional theory is the more flexible and consistent in identifying underlying psychological structures, because dimensional theory subsumes linear theory as a special case. The experiments demonstrate that by dimensional theory, there is no face-inversion effect for unfamiliar faces but a clear face-inversion effect for celebrity faces.     

Reexploring the connection between terror management theory and dissonance theory

Building upon suggestive earlier findings, the present study sought to test more informatively the notion that reminders of mortality can intensify efforts at dissonance reduction. Toward this end, an induced-compliance experiment was conducted in which participants were given high versus low choice to write a counterattitudinal statement regarding a boring topic under conditions of either mortality salience (MS) or uncertainty salience (control). It was predicted that although dissonance reduction (via attitude change) would be provoked in the control group, MS would significantly exacerbate this effect. These predictions were borne out empirically. The findings, obtained using the historically preeminent paradigm for assessing dissonance reduction, provide firm support for the notion that MS amplifies concerns with cognitive consistency.     

Separation-individuation theory and attachment theory

Separation-individuation and attachment theories are compared and assessed in the context of psychoanalytic developmental theory and their application to clinical work. As introduced by Margaret Mahler and John Bowlby, respectively, both theories were initially regarded as diverging from traditional views. Separation-individuation theory, though it has had to be corrected in important respects, and attachment theory, despite certain limitations, have nonetheless enriched psychoanalytic thought. Without attachment an infant would die, and with severely insecure attachment is at greater risk for serious disorders. Development depends on continued attachment to a responsive and responsible caregiver. Continued attachment to the primary object was regarded by Mahler as as intrinsic to the process of separation-individuation. Attachment theory does not account for the essential development of separateness, and separation-individuation is important for the promotion of autonomy, independence, and identity. Salient historical and theoretical issues are addressed, including the renewed interest in attachment theory and the related decline of interest in separation-individuation theory.     

Realism and the underdetermination of theory

The main theme is that theorizing serves empirical prediction. This is used as the core of a counter to contemporary anti-realist arguments. Different versions of the thesis that data underdetermines theory are identified and it is shown that none which are acceptable differentiates between theory selection and prediction. Criteria sufficient for the former are included amongst those necessary for the latter; and obviously go beyond mere compatibility with data.Special attention is given to causal process theories. It is argued that the only empirically equivalent alternatives which can be constructed to any theory of this kind must be parasitic on that theory; so a choice for the original theory can not be avoided. Once this is established, a positive case for taking a realist position can be developed.     

Bilattices and the theory of truth

Conclusion While Kripke's original paper on the theory of truth used a three-valued logic, we believe a four-valued version is more natural. Its use allows for possible inconsistencies in information about the world, yet contains Kripke's development within it. Moreover, using a four-valued logic makes it possible to work with complete lattices rather than complete semi-lattices, and thus the mathematics is somewhat simplified. But more strikingly, the four-valued version has a wide, natural generalization to the family of interlaced bilattices. Thus, with little more work, the theory is extended to a broad class of settings. Indeed, a result like Theorem 6.2 would not even be possible to state without the interlaced bilattice machinery. We hope the notion of interlaced bilattice will make apparent further such connections.     

Anthropology and the theory of medicine

Instead of presupposing reality as the “realists” do, a genetic theory of knowledge attempts to understand scientific knowledge through the psychological origins of both the concepts, and the operations on which these concepts are based. Adopting the viewpoint of genetic epistemology, the envisaged theory of medicine will have to perform a threefold task: (1) A revision and reformulation of the psycho-physical problem and the development of a model for the living body; (2) A revision of our views concerning the relationship between humans and the inanimate and animate environment; and (3) The development of a concept for the construction of individual reality and its consequences for the patient-physician relationship.     

Religion and the theory of masochism

The various aspects of masochistic personality structures provide a useful model for examining familiar elements of ordinary religious life. Overall theories of masochism can be divided into six general categories which trace masochism to 1) a distortion of love, 2) a need for punishment, 3) a payment for future rewards, 4) a strategy of the weak or powerless, 5) a flight from selfhood, or 6) an effort to be an object for others. In each case, religious analogies can be found exhibiting the same dynamics. Thus, certain religious phenomena may provide cultural or collective responses to the psychological needs at the root of masochism.240     

Explanation and the theory of questions

In The Scientific Image B. C. van Fraassen argues that a theory of explanation ought to take the form of a theory of why-questions, and a theory of this form is what he provides. Van Fraassen's account of explanation is good, as far as it goes. In particular, van Fraassen's theory of why-questions adds considerable illumination to the problem of alternative explanations in psychodynamics. But van Fraassen's theory is incomplete because it ignores those classes of explanations that are answers not to why-questions but to how-questions. In this article I provide a unified theory of explanatory questions that comprehends both how-questions and why-questions, and I show that a question-theoretic approach to explanation can be defended independently of van Fraassen's programme of Constructive Empiricism.
