The diagnostic process,the diagnosis and homeostasis

In this paper I shall try to analyse appropriate logic and actual methods as a preliminary to developing expert systems that will simulate clinical diagnosis. It is doubtful that all diagnoses address the same kind of problem and hence no one logic will suffice. Sometimes the signs and symptoms manifest an underlying disorder that cannot be observed directly (“the substantialist model”); sometimes there seems to be no underlying disorder and the diagnosis is a rearrangement of the data (“the nominalist model”). In deciding their merits in the particular case, we must identify the sources of variation; what is meant by saying that the data are independent; and what can be meant by “wrong” diagnosis and misclassification. Problems arise in human diagnosis because the data may be false, even lies; because the known list of diseases is not exhaustive; and because the probability of multiple unrelated diseases increases with age. Special difficulties arise from homeostasis (which is fundamental in defining and understanding disease) because the primary disturbances may be hard to distinguish from the homeostatic responses to them.     

Categorizing objects in isolation and in scenes: what a superordinate is good for

Many studies have shown that subjects are faster at categorizing objects into "basic" concepts than into more general superordinate concepts. However, all of these studies have used a categorization task in which single, isolated objects are identified. There is good reason to believe that superordinate concepts are typically used to refer to collections of objects rather than to individual objects. For example, people more often use the term furniture to refer to a number of pieces of furniture rather than to name a single piece. This suggest that superordinate concepts include information about multiple objects and their common relations, particularly the typical scenes in which such objects appear. Four experiments examined this possibility by investigating whether the basic concept advantage will decrease or reverse itself when subjects are asked to categorize an object as part of a scene. The results showed that the basic-superordinate difference did decrease when subjects categorized objects in scenes. Furthermore, when an object was placed in an inappropriate scene, there was more interference for superordinate identifications. The results suggest qualitative differences in the representations of superordinate and basic concepts.     

TRUTH, RELATIVISM, AND CROSSWORD PUZZLES

Abstract. Neither the correspondence nor the coherence theory of truth does justice to the truth claims made in science and theology. I propose a new definition that relates truth to solving puzzles. I claim that this definition is more adequate than either of the traditional theories and that it offers two additional benefits: first, it provides grounds for a theory regarding the relations between theology and science that may stand up better to philosophical scrutiny than does critical realism; and second, it blocks the move to relativism based on recognition of the plurality of perspectives and the historical and social conditioning of knowledge.     

A functional analysis of objects used in stereotyped behavior: The relationship between social and non-social stimuli

This study examined the effects of objects, with and without social stimulus properties, on the behavior of children who are severely retarded, and compared such effects with behavior under conditions of minimal stimulation. It was found that these children approach, contact, grasp and interact significantly less often with objects which possess social stimulus properties than with objects which possess no social qualities. These results are discussed in relation to the ongoing debate on the importance of relationships in the reduction of challenging behavior. It is concluded that while having access to close-bonded relationships may be necessary for the reduction of challenging behavior, in some cases at least, it may not be sufficient.     

What Can Be Learned from the Arts About Aging?

This brief article examines some of the theoretical questions raised by aesthetics. Paintings have not only form and content, but are underpinned by philosophical principles that connect art to gerontology. We examine specific theoretical messages of a trend in art that have important implications for conceptualizing humans, including their interactions and surroundings. Three artists are used to illustrate this trend: Cezanne, Picasso, and Pollock. These and other artists of this century foster a heightened awareness of humanistic concerns. Caught between abstract reason and expert systems on the one hand, and the life worlds of older people on the other, gerontology finds itself in a place where art can speak to its deeper concerns in unique ways.     

Anglo-American Postmodernity: A Response to Clayton and Robbins

In Anglo-American Postmodernity I call attention to recent intellectual shifts in epistemology (from foundationalism to holism), philosophy of language (from reference to use), and metaphysics (from reductionism to nonreductionism), and pursue the consequences of these changes for science, theology, and ethics. Wesley Robbins criticizes the book for making overly optimistic claims for the intellectual status of theology; Philip Clayton criticizes it for giving up the quest for general standards of rational progress. Both criticisms miss the mark in not taking on the account of rationality that I have developed from resources in the work of Alasdair MacIntyre.     

Effects of Race, Gender, Perceived Similarity, and Contact on Mentor Relationships

This study examined the effects of similarity, both actual (race and gender) and perceived, and amount of contact between mentor and protégé on the quality of mentor relationships. Mentor relationship quality was measured by liking, satisfaction, intended retention, and degree of psychosocial and instrumental functions experienced by the protégé. The participants were 104 summer intern protégés and their volunteer staff mentors employed at a large West coast media organization. Protégés were randomly assigned to one of two types of mentor pairings—same and different race mentors. Results indicate that liking, satisfaction, and contact with mentor were higher when protégés’ perceived themselves to be more similar to their mentors. Actual race pairing was related to protégés’ perceptions of the amount of career support and to mentors’ liking of protégés.     

FURTHER ANALYSIS OF THE RELATIONSHIP BETWEEN SELF-INJURY AND SELF-RESTRAINT

It has been suggested that self-restraint, a phenomenon often correlated with self-injurious behavior (SIB), may be maintained by negative reinforcement in the form of escape from the aversive properties of SIB (e.g., pain). We examined the effects of blocking SIB (and presumably removing any aversive effects) on the self-restraint of a 19-year-old male with severe mental retardation. Consistent with the negative reinforcement hypothesis, blocking SIB resulted in near-zero levels of SIB and moderate reductions in self-restraint.
