On the a priori and a posteriori assessment of probabilities

We argue that in spite of their apparent dissimilarity, the methodologies employed in the a priori and a posteriori assessment of probabilities can both be justified by appeal to a single principle of inductive reasoning, viz., the principle of symmetry. The difference between these two methodologies consists in the way in which information about the single-trial probabilities in a repeatable chance process is extracted from the constraints imposed by this principle. In the case of a posteriori reasoning, these constraints inform the analysis by fixing an a posteriori determinant of the probabilities, whereas, in the case of a priori reasoning, they imply certain claims which then serve as the basis for subsequent probabilistic deductions. In a given context of inquiry, the particular form which a priori or a posteriori reason may take depends, in large part, on the strength of the underlying symmetry assumed: the stronger the symmetry, the more information can be acquired a priori and the less information about the long-run behavior of the process is needed for an a posteriori assessment of the probabilities. In the context of this framework, frequency-based reasoning emerges as a limiting case of a posteriori reasoning, and reasoning about simple games of chance, as a limiting case of a priori reasoning. Between these two extremes, both a priori and a posteriori reasoning can take a variety of intermediate forms.     

Cogmic space for narrative-based world representation

Representing a world or a physical/social environment in an agent’s cognitive system is essential for creating human-like artificial intelligence. This study takes a story-centered approach to this issue. In this context, a story refers to an internal representation involving a narrative structure, which is assumed to be a common form of organizing past, present, future, and fictional events and situations. In the artificial intelligence field, a story or narrative is traditionally treated as a symbolic representation. However, a symbolic story representation is limited in its representational power to construct a rich world. For example, a symbolic story representation is unfit to handle the sensory/bodily dimension of a world. In search of a computational theory for narrative-based world representation, this study proposes the conceptual framework of a Cogmic Space for a comic strip-like representation of a world. In the proposed framework, a story is positioned as a mid-level representation, in which the conceptual and sensory/bodily dimensions of a world are unified. The events and their background situations that constitute a story are unified into a sequence of panels. Based on this structure, a representation (i.e., a story) and the represented environment are connected via an isomorphism of their temporal, spatial, and relational structures. Furthermore, the framework of a Cogmic Space is associated with the generative aspect of representations, which is conceptualized in terms of unconscious- and conscious-level processes/representations. Finally, a proof-of-concept implementation is presented to provide a concrete account of the proposed framework.     

Luther's Radical Conception of Faith: God,Christ, and Personhood in a Post‐Metaphysical Age

Luther's exposition of Paul's letter to the Galatians offers a premier window into a deconstruction of the tandem God, ego and symbolic order of the law by proposing a radical “technology of the self,” a new understanding of what it means to be a person in light of God's own becoming in the flesh—a new subjective perspective. This places the event of belief as a displacement of a socially and ecclesiastically constructed ego‐consciousness and the emergence of a new (social) center of subjectivity—Christ consciousness, that is, faith. For Luther the “person” emerges as a radical break with the self‐referentiality of the ego and through the perspectival assimilation of God's own subjective experience in the flesh.     

Timing multimodal events in pigeons

The peak procedure was used in two experiments to study pigeons' ability to time multimodal events. In the first experiment, birds were trained to time a single event consisting of a 9-s tone or light followed by a 21-s fixed interval associated with a signal of light or tone (signal of the other modality). On occasional empty trials, different lengths of the first signal were followed by a long period of the second signal. Peak response times as a function of the duration of the first signal were linear and had a slope of close to one in all birds. This indicates that the birds were timing only the second signal. In a second experiment, two complex events were used in training. One consisted of a 9-s tone or light followed by a 21-s fixed interval associated with a light or tone. The other consisted of a 21-s tone or light followed by a 9-s fixed interval associated with a light or tone. Different durations of the first signal were again used on empty trials. Peak response times as a function of the duration of the first signal were again linear in all birds. The slope of the function was less than one but greater than zero for 3 birds. This indicates that these birds were partly timing the entire complex event of 30-s duration and partly timing only the second signal of the event. A model is proposed in which the bird takes as a criterion for timing a weighted average of different target criteria. Comparisons with the performance of rats are made.     

Expérience de pré-deuil à l’approche du décès de son conjoint : une analyse phénoménologique interprétative

This article aims at scientifically investigating the anticipatory grief/mourning phenomenon, which is referred to the psychic processes before the death of a loved one, using the interpretative phenomenological analysis (IPA). The IPA is grounded on a phenomenological hermeneutic: the indepth study of the meaning-process of a subjective experience by a person. This analysis is applied to the case of a woman caring for her spouse suffering from a cancer, in end-of-life. The findings give an insight of the psychological functioning of a person facing the impending death of a relative, and offer reflection-tools concerning prevention of psychic distress in the bereavement field.     

Mimic automata: A novel formal model for mimic computing

In this paper, we aim to establish a mathematical model for mimic computing. To this end, we present a novel automaton called a mimic automaton. First, a one-dimensional cellular automaton is used for expressing some dynamic changes in the structure of a computing unit, a sequential automaton is employed to describe some state transitions, a hierarchical automaton is employed to express the different granularities of some computing units, and a probabilistic automaton is used to depict some random changes of a computing unit. Second, a mimic automaton is obtained by combining the various types of automata mentioned above in a certain logical relationship. Compared with the existing models of mimic computing, the new model portrays the operational semantics for a mimic computing system, and it can directly describe the behaviors of a system. Furthermore, the new model possesses a stronger generality.     

Choice, changing over, and reinforcement delays

In three experiments, pigeons were used to examine the independent effects of two normally confounded delays to reinforcement associated with changing between concurrently available variable-interval schedules of reinforcement. In Experiments 1 and 2, combinations of changeover-delay durations and fixed-interval travel requirements were arranged in a changeover-key procedure. The delay from a changeover-produced stimulus change to a reinforcer was varied while the delay between the last response on one alternative and a reinforcer on the other (the total obtained delay) was held constant. Changeover rates decreased as a negative power function of the total obtained delay. The delay between a changeover-produced stimulus change had a small and inconsistent effect on changeover rates. In Experiment 3, changeover delays and fixed-interval travel requirements were arranged independently. Changeover rates decreased as a negative power function of the total obtained delay despite variations in the delay from a change in stimulus conditions to a reinforcer. Periods of high-rate responding following a changeover, however, were higher near the end of the delay from a change in stimulus conditions to a reinforcer. The results of these experiments suggest that the effects of changeover delays and travel requirements primarily result from changes in the delay between a response at one alternative and a reinforcer at the other, but the pattern of responding immediately after a changeover depends on the delay from a changeover-produced change in stimulus conditions to a reinforcer.     

Sense and Reference of Predicates: Comments on Frege’s Theory of Sense-Reference

Frege argued that a predicate was a functional expression and the reference of it a concept, which as a predicative function had one or more empty places and was thus incomplete. Frege’s view gives rise to what has been known as the paradox of the concept “horse.” In order to resolve this paradox, I argue for an opposite view which retains the point that a predicate is a function, i.e. that a predicative function is complete in a sense. Specifically speaking, a predicate performing the function of a predicate has at least one empty place and has no reference, while a predicate performing the function of a subject does not have any empty place but does have a reference. Frege not only regarded a concept with one or more empty places as the reference of a predicate but also took a set of objects without any empty place to be the extension of a concept with one or more empty places. Thus, it presents a complex relationship between the reference of a predicate and its corresponding extension, leading to disharmony in his theory. I argue that this is because there is a major defect in Frege’s theory of meaning, namely the neglect of common names. What he called extensions of concepts are actually extensions of common names, and the references of predicates and the extensions of common names have a substantial difference despite being closely related.     

Memory for recent behavior in the pigeon

Variations of the symbolic delayed-matching-to-sample procedure were used to study a pigeon's memory for a small number of pecks. In the first experiment a choice of a left or right sidekey after a delay or retention interval was reinforced if a bird had not pecked at all or had pecked exactly once, before the delay, respectively. In the second experiment a choice of a red or green sidekey, regardless of its position, was reinforced if a bird had not pecked at all or had pecked exactly twice, respectively. In the first experiment a bird could orient toward the correct choice during the delay, whereas it could not in the second experiment. In a third experiment a feature-probing method was used to study a pigeon's memory for a number of pecks in the context of certain other pecks. The results showed that a pigeon can remember a small number of pecks for one-half to one minute or more and that the percent correct is a decreasing function of the log retention interval. When a second number of pecks is different from the first number, memory for the first number lasts only a few seconds. When a second number is the same, memory lasts considerably longer. The more recent number of pecks is remembered better. The results are interpreted in terms of a theory which holds that a reinforcer, in general, may act on a subjects' memory for recent behavior to generate patterns of behavior.     

Consider the source: One step in assessing premise acceptability

Premise acceptability is conceptually connected to presumption. To say that a premise is acceptable just when there is a presumption in its favor is to give a first approximation to this connection. A number of popular principles of presumption suggest that whether there is a presumption for a premise, belief, or claim depends on the sources which vouch for it. Sources consist of internal belief-generating mechanisms and external testimony. Alvin Plantinga's notion of warrant lays down four conditions upon a source for the belief which it generates to be warranted. We argue that there is a presumption for a premise, belief, or claim if and only if there is a presumption of warrant for that premise,belief or claim. This amounts to the thesis that there is a presumption for a belief from a challenger's point of view if and only if there is a presumption from that person's point of view that her cognitive faculties which have generated the belief have been functioning properly, in an appropriate cognitive environment, in accord with a segment of her design plan aimed at the truth, and that these faculties are reliable. In light of our argument for this thesis, we may legitimately claim that one way to determine that there is a presumption for a belief is to determine that there is a presumption of warrant for that belief, and thus that in determining whether there is a presumption for a belief or premise, we may consider the source.     

Plato's Criticism of the ``Democratic Man' in the Republic

The article discusses two puzzles about Plato's account of the democratic person: (1) unlike his account of the democratic city, his characterization of a democratic person is markedly incorrect. (2) His criticism of a person so characterized is criticism of a straw man. The article argues that the first puzzle is resolved if we see it as a result of Plato's assumption that a democratic person is a person whose soul is isomorphic to a democratic constitution. Such a person has a desire satisfaction theory of good and adopts liberty and equality of desires as a basis for action. The article then argues that Plato's criticism brings up two problems endemic to desire satisfaction theories of good, the problem of bad desires and the problem of conflicts of desires. The criticism is that the democratic person's way of dealing with these problems, by applying the social principles of liberty and equality to his desires, is irrational.     

People Make the Place: Religious Leadership and the Identity of the Local Congregation

The identity of a congregation is more dependent on the people who gather together than on any particular constellation of structures and strategies, programs, and policies. While social processes of attraction, selection and attrition are fundamental to identity development, a paradoxical consequence is that a strong identity is unavoidably linked to a degeneration of the congregation’s vitality and to a reduction of its capacity for survival in a changing environment. The arrival of a new religious leader may help to halt the growing degeneration and incapacity by the minister becoming the center of a new cycle of attraction, selection, and attrition. However such a renewal in identity is always rife with conflict and therefore contrary to the idea of a religious congregation as a harmonious and peaceful assembly of believers.     

THREE THEORIES OF HUMAN NATURE

In The Blank Slate: The Modern Denial of Human Nature, Steven Pinker maintains that at present there are three competing views of human nature—a Christian theory, a “blank slate” theory (what I call a social constructivist theory), and a Darwinian theory—and that the last of these will triumph in the end. I argue that neither the outcome of such competition nor the particular content of these theories is as clear as Pinker believes. In this essay I take a critical as well as a constructive look at the challenge presented by a Darwinian theory of human nature—a challenge to the social sciences and the humanities and also to theology and more specifically to a Christian understanding of human nature.     

INTERPRETATION AND THE ORIGIN OF LIFE

We offer a general definition of interpretation based on a naturalized teleology. The definition tests and extends the biosemiotic paradigm by seeking to provide a philosophically robust resource for investigating the possible role of semiosis (processes of representation and interpretation) in biological systems. We show that our definition provides a way of understanding various possible kinds of misinterpretation, illustrate the definition using examples at the cellular and subcellular level, and test the definition by applying it to a potential counterexample. We explain how we propose to use the definition as a way of asking new questions about what distinguishes life from non‐life and of formulating testable hypotheses within the field of origin‐of‐life research. If the definition leads to fruitful new empirical approaches to the scientific problem of the origin of life, it will help to establish biosemiotics as a legitimate philosophical approach in theoretical biology and will thereby support a theological appropriation of the biosemiotic perspective as the basis of a new theology of nature.     

Variables affecting establishment of schedule-induced attack on pictorial targets in White King pigeons.

White King pigeons exposed to food schedules before introduction of a colored photograph of a pigeon showed sustained schedule-induced attack on that image; additional birds given an early introduction to both the photograph and the schedule subsequently attacked the image at lower rates. Other pigeons attacked a second photograph of a pigeon regardless of whether it was introduced early or late. The late-introduction procedure was also effective in establishing attack on a projected image of a conspecific. The combined results showed that 14 of 17 White King pigeons given a late introduction to a pictorial target exhibited sustained attack against it and that a pigeon's initial reaction to a photograph of a conspecific when introduced early was a good predictor of subsequent schedule-induced attack on it.     

Cybersemiotics and the Question of Semiotic and Informational Thresholds

The present article discusses various suggestions for a philosophical framework for a transdisciplinary information science or a semiotic doctrine. These are: the mechanical materialistic, the pan-informational, the Luhmanian second order cybernetic approach, Peircian biosemiotics and finally the pan-semiotic approach. The limitations of each are analyzed. The conclusion is that we will not have to choose between either a cybernetic-informational or a semiotic approach. A combination of a Peircian-based biosemiotics with autopoiesis theory, second order cybernetics and information science is suggested in a five-leveled cybersemiotic framework. The five levels are 1) a level of Firstness, 2) a level of mechanical matter, energy and force as Secondness, 3) a cybernetic and thermodynamic level of information and signal, 4) a level of sign games in living systems, and 5) a level of conscious language games in self-conscious social humans.

A Psychoanalytic Dialectical Model for Sexual and Other Forms of Workplace Harassment

Beginning with a brief literature review, the present paper outlines a dialectical model for sexual and other forms of workplace harassment in which the role dependent models of bully, victim and bystander are seen to complexly interact and facilitate each other. An organization which has a bully always has the other two roles represented according to the model. It is suggested that for a workplace to function harmoniously all three roles must be addressed, and the power struggle resolved. The theory is illustrated with a series of case studies drawn from a forensic psychiatry practice. These include some more unusual forms of harassment such as the harassment of a Mexican American woman by an African American woman, the harassment of a middle-aged conservative man by two young women, the harassment of a man by several male employees together with traditional patterns of an older male employer harassing a younger female employee. Psychoanalytic processes which explain the pathological patterns are illustrated with material drawn from a psychoanalysis of a harassed woman. The paper concludes with some brief suggestions for a plan for workplace intervention.     

Looking to understand: the coupling between speakers' and listeners' eye movements and its relationship to discourse comprehension

We investigated the coupling between a speaker's and a listener's eye movements. Some participants talked extemporaneously about a television show whose cast members they were viewing on a screen in front of them. Later, other participants listened to these monologues while viewing the same screen. Eye movements were recorded for all speakers and listeners. According to cross-recurrence analysis, a listener's eye movements most closely matched a speaker's eye movements at a delay of 2 sec. Indeed, the more closely a listener's eye movements were coupled with a speaker's, the better the listener did on a comprehension test. In a second experiment, low-level visual cues were used to manipulate the listeners' eye movements, and these, in turn, influenced their latencies to comprehension questions. Just as eye movements reflect the mental state of an individual, the coupling between a speaker's and a listener's eye movements reflects the success of their communication.     

Spoon-to-cup fading as treatment for cup drinking in a child with intestinal failure

We treated a child with intestinal failure who consumed solids on a spoon but not liquids from a cup. We used spoon-to-cup fading, which consisted of taping a spoon to a cup and then gradually moving the bowl of the spoon closer to the edge of the cup. Spoon-to-cup fading was effective for increasing consumption of liquids from a cup.
