Phenomenology and the Third Generation of Cognitive Science: Towards a Cognitive Phenomenology of the Body

Phenomenology of the body and the third generation of cognitive science, both of which attribute a central role in human cognition to the body rather than to the Cartesian notion of representation, face the criticism that higher-level cognition cannot be fully grasped by those studies. The problem here is how explicit representations, consciousness, and thoughts issue from perception and the body, and how they cooperate in human cognition. In order to address this problem, we propose a research program, a cognitive phenomenology of the body, which is basically motivated by the perspective of Merleau-Ponty. We find a substantial clue in developmental psychological studies on the body and language.

Are There Stable Factors in Preadolescent Girls’ Externalizing Behaviors?

Relatively little is known about the factor structure of disruptive behavior among preadolescent girls. The present study reports on exploratory and confirmatory factor analyses of disruptive girl behavior over four successive data waves as rated by parents and teachers in a large, representative community sample of girls (N = 2,451). Five factors were identified from parent ratings (oppositional behavior/conduct problems, inattention, hyperactivity/impulsivity, relational aggression, and callous-unemotional behaviors), and four factors were identified derived from teacher ratings (oppositional behavior/conduct problems/callous-unemotional behaviors, inattention, hyperactivityimpulsivity, and relational aggression). There was a high degree of consistency of items loading on equivalent factors across parent and teacher ratings. Year-to-year stability of factors between ages five and 12 was high for parent ratings (ICC = 0.70 to 0.88), and slightly lower for teacher ratings (ICC = 0.56 to 0.83). These findings are discussed in terms of possible adjustment to the criteria for children's disruptive behavior disorders found in the Diagnostic and Statistical Manual for Mental Disorders.

Towards a New Epistemology of Mathematics

In this introduction we discuss the motivation behind the workshop “Towards a New Epistemology of Mathematics” of which this special issue constitutes the proceedings. We elaborate on historical and empirical aspects of the desired new epistemology, connect it to the public image of mathematics, and give a summary and an introduction to the contributions to this issue.

Worlds are colliding! Explaining the fictional in terms of the real

I discuss Gregory Currie’s taxonomy of explanations of the fictional. On the one hand, there is an important kind of relation between internal and external explanations of some fictional truths that Currie leaves out, where both are salient and yet in a relation of harmony with each other. On the other hand, I do not see that he has established that there is a genuine relation of tension between some pairs of internal and external explanations, and thus I question the usefulness of the category of collapse. I also consider a further kind of explanation: the exterior explanation.

Dynamical agents: Consciousness, causation, and two specters of epiphenomenalism

The aim of this paper is to defend the causal efficacy of consciousness against two specters of epiphenomenalism. We argue that these challenges are best met, on the one hand, by rejecting all forms of consciousness-body dualism, and on the other, by adopting a dynamical systems approach to understanding the causal efficacy of conscious experience. We argue that this non-reductive identity theory provides the theoretical resources for reconciling the reality and efficacy of consciousness with the neurophysiology of the brain and body.

Constructive and deconstructive tool modification by chimpanzees (Pan troglodytes)

Nine chimpanzees (Pan troglodytes) were tested for their ability to assemble or disassemble the appropriate tool to obtain a food reward from two different apparatus. In its deconstructed form, the tool functioned as a probe for one apparatus. In its constructed form, the tool functioned as a hook, appropriate for a second apparatus. Each subject completed four test trials with each apparatus type. Tool types were randomized and counter-balanced between the two forms. Results demonstrated that adult and juvenile chimpanzees (N = 7) were successful with both tool types, while two infant chimpanzees performed near chance. Off-line video analyses revealed that tool modifications followed by attempted solutions by the adults and juveniles were typically correct on the first attempt. Neither infant was successful in modifying tools correctly on the first attempt over all eight trials. The older chimpanzees’ ability to modify the appropriate tool consistently prior to use indicates an immediate recognition of the functional attributes necessary for the successful use of tool types on each apparatus, and represents a non-replication of a previously reported study by Povinelli.

On the Division Between Reason and Unreason in Kant

This article examines Kant’s discussion of the division between reason and unreason in his Anthropology from a Pragmatic Point of View. On the one hand, Kant says that there is a normative, clear, and definite division between reason and unreason. On the other hand, Kant offers three arguments showing that we cannot draw such a division. First, we cannot explain the normative grounds for the division. Second, both reason and unreason are present in everyone to varying degrees in different ways. Third, Kant invalidates the division as such by characterizing what should be more incomprehensible than an extreme case of unreason as also being a rational way of life.

Action planning with two-handed tools

In tool use, the intended external goals have to be transformed into bodily movements by taking into account the target-to-movement mapping implemented by the tool. In bimanual tool use, this mapping may depend on the part of the tool that is operated and the effector used (e.g. the left and right hand at the handle bar moving in opposite directions in order to generate the same bicycle movement). In our study, we investigated whether participants represent the behaviour of the tool or only the effector-specific mapping when using two-handed tools. In three experiments, participants touched target locations with a two-jointed lever, using either the left or the right hand. In one condition, the joint of the lever was constant and switching between hands was associated with switching the target-to-movement-mapping, whereas in another condition, switching between hands was associated with switching the joint, but the target-to-movement-mapping remained constant. Results indicate pronounced costs of switching hands in the condition with constant joint, whereas they were smaller with constant target-to-movement mapping. These results suggest that participants have tool-independent representations of the effector-specific mappings.

Sosa in perspective

Ernest Sosa draws a distinction between animal knowledge and reflective knowledge, and this distinction forms the centerpiece of his new book, A Virtue Epistemology. This paper argues that the distinction cannot do the work which Sosa assigns to it.

Introduction: Postphenomenological Research

This introduction to the special issue of Human Studies on postphenomenology outlines specific developments which have led to this style of phenomenology. Postphenomenology adapts aspects of pragmatism, including its anti-Cartesian program against early modern subject/object epistemology. Postphenomenology retains and emphasizes the use of phenomenological variations as an analytic tool, and in practice postphenomenology takes what is commonly now called “an empirical turn,” which deeply analyzes case studies or concrete issues under its purview.

Actuality and possibility: On the complementarity of two registers in the bodily constitution of experience

The purpose of this paper is to demonstrate the usefulness of the concept of possibility, and not merely that of actuality, for an inquiry into the bodily constitution of experience. The paper will study how the possibilities of action that may (or may not) be available to the subject help to shape the meaning attributed to perceived objects and to the situation occupied by the subject within her environment. This view will be supported by reference to empirical evidence provided by recent and current research on the perceptual estimation of distances and the effects brought about by the use of a tool on the organisation of our perceived immediate space.

Visualizations in Mathematics

In this paper we discuss visualizations in mathematics from a historical and didactical perspective. We consider historical debates from the 17th and 19th centuries regarding the role of intuition and visualizations in mathematics. We also consider the problem of what a visualization in mathematical learning can achieve. In an empirical study we investigate what mathematical conclusions university students made on the basis of a visualization. We emphasize that a visualization in mathematics should always be considered in its proper context.

Disembodied Minds and the Problem of Identification and Individuation

We consider and reject a variety of attempts to provide a ground for identifying and differentiating disembodied minds. Until such a ground is provided, we must withhold inclusion of disembodied minds from our picture of the world.

European Regulatory Issues in Nanomedicine

The paper is intended to focus on peculiarities of nanomedicine and the importance of social concerns implicated, in order to understand if existing regulations are appropriate to maintain its safety or if a new ad hoc regulatory framework is needed. Consideration of social challenges will underline the crucial role of medical ethics in regulatory discussion.

Gert on Subjective Practical Rationality

The purpose of this paper is to consider Joshua Gert’s novel view of subjective practical rationality in his book Brute Rationality. After briefly outlining the account, I present two objections to his view and then consider his own objections to a rival approach to understanding subjective rationality which I take to be much more plausible.
