Visual space as physical geometry

The geometrical incongruence between patterns in visual space and structures and patterns of activity in the visual cortex, long known to investigators, serves as a criterion for evaluating physical theories of visual space. The problem of determining the geometry of the visual world (visual geometry) is compared with that of determining the geometry of the physical world (physical geometry). Theories as to the possible physical locus of visual space, whether in the brain or elsewhere, are reviewed, analyzed, and criticized accordingly. It is concluded that on the basis of congruence alone it would be predicted that visual space is not to be found in the brain, even though it is seemingly linked to it causally, as experimental neurology and neurophysiology demonstrate. Alternative theories as to the nature of visual space are considered, but are also found to be inadequate in explaining visual space in terms acceptable to contemporary science.     

Logic for physical space

Since the early days of physics, space has called for means to represent, experiment, and reason about it. Apart from physicists, the concept of space has intrigued also philosophers, mathematicians and, more recently, computer scientists. This longstanding interest has left us with a plethora of mathematical tools developed to represent and work with space. Here we take a special look at this evolution by considering the perspective of Logic. From the initial axiomatic efforts of Euclid, we revisit the major milestones in the logical representation of space and investigate current trends. In doing so, we do not only consider classical logic, but we indulge ourselves with modal logics. These present themselves naturally by providing simple axiomatizations of different geometries, topologies, space-time causality, and vector spaces.

Ernst Cassirer as cultural scientist

The article investigates Cassirer’s developing interest in the cultural sciences to display how his Philosophy of Symbolic Forms constitutes a philosophy of culture. The core concept in such a philosophy of culture is the symbolic formation that both possesses a structured-structuring dimension and appears as an historical process in which culture shows itself as a temporal creation. The philosophy of culture displays ‘life in meaning’, that is reality as it exhibits human reality manifested in and through the medium of linguistic, artistic, religious, scientific “and so on” action and behaviour. This reality, therefore, is mediation between culture and nature through human spirit. Cassirer’s philosophy of culture connects back to Kant’s transcendental idealism by emphasizing that any concept of reality establishes itself through a modalization of reality, e.g. that reality constitutes itself in the mode of interpretation. This makes the basis for Cassirer’s characteristic understanding of hermeneutics where cultural development is regarded as drama.     

Emotional valence and physical space: limits of interaction

According to the body-specificity hypothesis, people associate positive things with the side of space that corresponds to their dominant hand and negative things with the side corresponding to their nondominant hand. Our aim was to find out whether this association holds also true for a response time study using linguistic stimuli, and whether such an association is activated automatically. Four experiments explored this association using positive and negative words. In Exp. 1, right-handers made a lexical judgment by pressing a left or right key. Attention was not explicitly drawn to the valence of the stimuli. No valence-by-side interaction emerged. In Exp. 2 and 3, right-handers and left-handers made a valence judgment by pressing a left or a right key. A valence-by-side interaction emerged: For positive words, responses were faster when participants responded with their dominant hand, whereas for negative words, responses were faster for the nondominant hand. Exp. 4 required a valence judgment without stating an explicit mapping of valence and side. No valence-by-side interaction emerged. The experiments provide evidence for an association between response side and valence, which, however, does not seem to be activated automatically but rather requires a task with an explicit response mapping to occur.     

Premenstrual syndrome as scientific and cultural artifact

Premenstrual Syndrome (PMS) has been defined in a variety of scientific and cultural ways over the years, but there is no consistent or agreed upon definition. For some women, the public legitimization of PMS and its symptoms as a real and natural part of the female body have led to a positive sense of vindication. However, a more negative image of PMS as something that controls women once a month, that makes them “crazy” and subject to their hormones, is much more pervasive in our contemporary Western culture. In this essay, the author explores the various definitions: PMS as a medical condition, as a social scientific and feminist issue, as an explanation for women's behavior and moods in the popular culture, and, finally, as something bought or sold in a market. The author shows how PMS is real because, if for no other reason, various people in different situations choose to define it as such.

A tutorial on Bayes factor estimation with the product space method

The Bayes factor is an intuitive and principled model selection tool from Bayesian statistics. The Bayes factor quantifies the relative likelihood of the observed data under two competing models, and as such, it measures the evidence that the data provides for one model versus the other. Unfortunately, computation of the Bayes factor often requires sampling-based procedures that are not trivial to implement. In this tutorial, we explain and illustrate the use of one such procedure, known as the product space method (Carlin & Chib, 1995). This is a transdimensional Markov chain Monte Carlo method requiring the construction of a “supermodel” encompassing the models under consideration. A model index measures the proportion of times that either model is visited to account for the observed data. This proportion can then be transformed to yield a Bayes factor. We discuss the theory behind the product space method and illustrate, by means of applied examples from psychological research, how the method can be implemented in practice.     

Spacetime theory as physical geometry

Discussions of the metaphysical status of spacetime assume that a spacetime theory offers a causal explanation of phenomena of relative motion, and that the fundamental philosophical question is whether the inference to that explanation is warranted. I argue that those assumptions are mistaken, because they ignore the essential character of spacetime theory as a kind of physical geometry. As such, a spacetime theory does notcausally explain phenomena of motion, but uses them to construct physicaldefinitions of basic geometrical structures by coordinating them with dynamical laws. I suggest that this view of spacetime theories leads to a clearer view of the philosophical foundations of general relativity and its place in the historical evolution of spacetime theory. I also argue that this view provides a much clearer and more defensible account of what is entailed by realism concerning spacetime.I would like to thank William Demopoulos and Michael Friedman for their comments on earlier drafts.

Fiat's cultural revolution: TQM as functional integration

The opening decade of this millennium witnessed genome scientists, policy makers, critical race theorists and world leaders standing together to pronounce the anti-racist democratic potential of human genomics. Understanding and assessing this rise of ‘anti-racist, democratic genomics’ requires distinguishing between two problems of power and science: the first characterized by what Michel Foucault labeled states of domination; the second by what he described as relations of power. When states of domination exist, as in the case of Nazi science, liberal efforts to extend new powers of participation and autonomy to research subjects may play important roles in redressing power imbalances between researchers and their subjects. However, when distinctions between scientist and research subject blur, as in the case of much human genomics, efforts to extend liberal rights to subjects of genomic studies—or genomic liberalism—may produce novel problems, including: (1) human genome scientists' loss of capacity to describe their objects of study; (2) disruption of research subjects' abilities to define themselves; and (3) lack of accountability for the unintended effects of efforts to democratize genomics. In these ways genomic liberalism may foster, at the same that it impedes, the co-constitution of knowledge and democratic subjects. It may create new forms of racism at the very moment that it explicitly seeks anti-racist ends. Addressing the problems created by this paradoxical position will require more sustained attention to and critique of the anti-racist and democratic imaginaries that increasingly animate technoscience.     

The protestant work ethic as a cultural phenomenon

A central contention of much of the literature about the nature of work values and the meaning of work is that there is (or at least has been) a consensual work ethic operating in modern industrial societies. This premise has surprisingly, rarely been put to the test. In this paper, evidence for a modern work ethic is obtained from the European Values Survey. The link between this work ethic and religion is then explored. While one conclusion of the analysis is that it is still an identifiably Protestant ethic, contextual analysis demonstrates that the effect of a country's religious culture is more potent than the religious beliefs of the individual.     

Female physical attractiveness in Britain and Japan: a cross‐cultural study

Two purported cues to female physical attractiveness are body mass index (BMI) and body shape as measured by the waist‐to‐hip ratio (WHR). This study examined the relative contribution of both cues in two culturally distinct populations. Eighty‐two male participants from Britain and Japan were asked to rate a set of images of real women with known BMI and WHR. Results showed that BMI is the primary determinant of female physical attractiveness, whereas WHR failed to emerge as a significant predictor. Results also showed that there were significant differences in preferences for physical attractiveness, with Japanese participants preferring images of women with significantly lower BMIs than Britons. Finally, results showed that the Japanese are more reliant on body shape than Britons when judging physical attractiveness. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theories which emphasise the learning of preferences in social and cultural contexts.

Consciousness as a concrete physical phenomenon

The typical empirical approach to studying consciousness holds that we can only observe the neural correlates of experiences, not the experiences themselves. In this paper we argue, in contrast, that experiences are concrete physical phenomena that can causally interact with other phenomena, including observers. Hence, experiences can be observed and scientifically modelled. We propose that the epistemic gap between an experience and a scientific model of its neural mechanisms stems from the fact that the model is merely a theoretical construct based on observations, and distinct from the concrete phenomenon it models, namely the experience itself. In this sense, there is a gap between any natural phenomenon and its scientific model. On this approach, a neuroscientific theory of the constitutive mechanisms of an experience is literally a model of the subjective experience itself. We argue that this metatheoretical framework provides a solid basis for the empirical study of consciousness.     

The group as an object in the cultural field

This paper illuminates the interplay between group and individual processes by exploring members' notions of the group itself. What members hold in common about the "group" is understood as an object in the cultural field, which is a particular kind of transitional phenomenon (Winnicott). The paper connects this notion to Bion's concept of "basic assumptions," and describes members' motivations for creating the "group" as well as its role in the psychotherapy group. The object in the cultural field is then further elaborated in its more general role in the relation between the individual and the group, which leads to a consideration of psychotherapy groups in terms of their value in facilitating living in the social world.
