Between the Rock and a Hard Place: In Support of (something like) a Reformed View of the Eucharist

In this article, Calvin's eucharistic theology is re-read in the light of Aquinas, Augustine, Irenaeus, Luther, Jean-Luc Marion, Graham Ward and Catherine Pickstock. It is found to have great strengths, sucessfully avoiding both static ideas of Christ's presence and individual nominalism, while allowing a prominent place for the Holy Spirit and room for the believer's faith. Calvin took account of the doctrine of the Ascension quite differently from Luther by stressing Christ's bodily absence from this world. The article argues that this dialectic of presence and absence would gain from giving it a temporal dimension, giving more weight to eschatology.     

<Emphasis Type="Italic">Revolutionary Becomings</Emphasis>: Negritude's Anti-Humanist Humanism

In this paper I establish an alliance between the thought of Frantz Fanon and Gilles Deleuze's Philosophy of Difference. In light of Fanon's critique of Sartre's characterization of the place of the Negritude movement in terms of dialectic, I point to the inherent limitations of modern humanism's dialectical accounts for enabling genuine historical change. Alternatively, I appeal to Deleuze's distinction between history and becoming, and his concomitant idea of intensive becoming-revolutionary. I conclude that such an alliance with Deleuzian metaphysics holds far greater promises for effecting Fanon's revolutionary project of the creation of a new humanity (and therefore, of a new ethics and a new politics) than his traditional assimilation to Phenomenology and Existentialism.     

Before Analogy: Recovering Barth'sOntological Development

What is the nature of Barth's development over the 1920s? Barth himself understood this period as his "apprenticeship," and cites his 1931 book on Anselm as a significant juncture in moving beyond this stage in his thinking. Barth's emphasis upon both change and continuity lies at the heart of the discrepancy between two prominent interpreters of his theology, Hans Urs von Balthasar and Bruce McCormack. On the surface it appears as though their disagreement centers around Barth's employment of dialectic and analogy in his theology. However, our thesis is that this focus conceals the ontological strategies Barth's multifarious uses of analogy and dialectic always implied. Although McCormack is right to suggest that Balthasar's depiction of a shift from dialectic to analogy is inadequate, in the end McCormack's account of Barth's development over the 1920s conceals as much as it reveals. The following essay attempts to demonstrate the kinds of insights which can be made of the past accounts of Barth's development which focused on the transition from dialectic to analogy. Far from relegating these accounts to the sidelines, McCormack's work helps us see all the more clearly just what was at stake in figures like Balthasar's work. By looking past McCormack and Balthasar's respective periodizations of Barth's development, a clearer focus upon Barth's theological ontology can begin to take place.     

Are ants sensitive to the geometry of tunnel bifurcation?

The ability to orient and navigate in space is essential for all animals whose home range is organized around a central point. Because of their small home range compared to vertebrates, central place foraging insects such as ants have for a long time provided a choice model for the study of orientation mechanisms. In many ant species, the movement of individuals on their colony home range is achieved essentially collectively, on the chemical trails laid down by their nest mates. In the initial stage of food recruitment, these trails can cross each other and thus form a network of interconnected paths in which ants have to orient. Previous simulation studies have shown that ants can find the shortest path between their nest and a food source in such a network only if there is a bias in the branch they choose when they reach an asymmetrical bifurcation. In this paper, we studied the choice of ants when facing either a symmetrical or an asymmetrical bifurcation between two tunnels. Ants were tested either on their way to a food source or when coming back to their nest, and either in the presence or in the absence of a chemical trail. Overall, our results show that the choice of an ant at a tunnel bifurcation depends more on the presence/absence of a trail pheromone than on the geometry of the bifurcation itself.     

A Dialectic on Validity: Where We Have Been and Where We Are Going

It has been suggested that the primary issue in considerations of validity today is the discrepancy between currently accepted theory and the practice of validation. The reason for this discrepancy may be that although considerable discussion has taken place in educational measurement and psychometrics regarding changes in our conceptions of validity, that has not been the case more generally in the social and behavioral sciences. A dialectic on the current status of validity theory for social and behavioral scientists is presented to help bridge this gap.     

Promoting an Empathic Dialectic for Therapeutic Change: An Integrative Review

This integrative review is focused on a formulation of therapeutic empathy. We describe the “empathic dialectic” as therapists’ capacity to emotionally resonate with patients’ internal states, such as during ruptures, and to coregulate their own and the patients’ states through mentalization. The first aim was to provide a theoretical framework for the empathic dialectic, by summarizing background literature on the empathic process, intersubjectivity, rupture repair, relational psychoanalysis, and attachment. The second aim was to conduct an integrative review of peer-reviewed articles published between the years of 2016 and 2021. After conducting a review of 28 articles, we sought to identify (1) research that supports the existence of an empathic dialectic, (2) evidence that therapists’ attachment influences the empathic dialectic, and (3) implications of the empathic dialectic for training and supervision. Results pointed to the central role of therapists’ attachment security in the empathic dialectic, and the negative repercussions of therapists’ insecurity when mentalization is underdeveloped. Results also highlighted the role of supervision as a means of enhancing trainees’ self-awareness of their attachment, and its impact on the alliance. As the American Psychological Association embraces a clinical competencies model in its accreditation of clinical psychology doctoral programs, the importance of attaining an integrative understanding of therapeutic empathy has become increasingly imperative. To this end, we conclude by promoting the empathic dialectic as a key clinical competency, and providing further recommendations for training and supervision.

     

‘I love you’. How to understand love in couple therapy? Exploring love in context

Acknowledging the place of love in couple therapy requires therapists to reflect upon what love means to them. We propose that love defines the couple relationship and in turn the relationship defines love. In this article we explore and focus on our conceptualization of love and its influence on couple therapy. Exploring love in the context of the phrase ‘I love you’ leads us to consider built‐in contradictions. These contradictions can be contextualized and understood in a relational dialectic framework. Implications for therapy are explored and briefly illustrated in a case vignette.     

The role of working memory capacity in implicit and explicit sequence learning of children: Differentiating movement speed and accuracy

This study investigated the role of working memory capacity on implicit and explicit motor sequence learning in young children. To this end, a task was utilized that required a gross motor response (flexing the elbow) and that could differentiate between movement speed (i.e., reaction time and movement time) and movement accuracy. Children aged 7–9 years practiced a serial reaction time task that involved the production of a fixed sequence of elbow flexions of prescribed magnitude across two consecutive days. Children in the explicit group were informed about the presence of the sequence and were shown this sequence, while children in the implicit group were not made aware of the sequence. Additionally, children's verbal and visuospatial working memory capacity was assessed. Results of day 1 regarding movement speed revealed no evidence of sequence learning for either group, but movement accuracy results suggested that sequence learning occurred for the implicit group. For both groups, only improvements in movement accuracy were consolidated on day 2, indicating both general and sequence specific learning. Working memory capacity did not correlate with learning in either of the groups. Children in the explicit group accumulated more sequence knowledge compared to children in the implicit group, but this knowledge did not translate to more or better sequence learning. The minimal differences found between the implicit and explicit condition and the absence of a role for working memory capacity add to the increasing evidence that the observed differences between implicit and explicit sequence learning in adults may be less distinct in children.     

Reversals of visual depth caused by motion parallax

The role of the velocity and direction of retinal movement in the determination of apparent depth from motion parallax was examined. Motion parallax was produced either by linking the movement of random-dots to head movement or by making this motion independent of the head movement. The results show that apparent depth was largely estimated from the velocity difference between the stimuli. The direction of retinal movement in the absence of head movement did not determine whether the pattern appeared to protrude or recede. Information about direction linked to head movement was able to stabilize protrusion/recession by providing a cue for the location of the fixation point. Depth reversal occurred less frequently in the presence than in the absence of head movement. When the fixation point shifted from the apparently protruding pattern to the apparently receding pattern, in both the presence and absence of head movement, depth reversal was readily observed.     

Apparent movement detection in the pigeon

Pigeons were trained to discriminate between the presence and absence of apparent movement in visual displays. Generalization gradients obtained on the dimension of speed indicated a broad range of movement detection. Extremely accurate discrimination performance on displays varying in direction of movement suggested formation of a "movement concept".     

Existentialism And The Environment

This article examines the possible contributions the existentialist tradition might make to environmentalism. I note, first, that Martin Heidegger is a questionable ally, both because his relationship to technology is ambiguous, while his affiliations with the Nazis were not. But the larger existentialist tradition is valuable for the environmental movement because it opens up a field of possibilities for human creativity. Sartre serves as exemplary for the way he struggled with the dialectic between individual autonomy in his early philosophy of freedom, and the needs of the collective as he confronted them in his later turn toward Marxism. But the demands of the collective are more reasonably confronted in the larger legacy of Hegel than in the more limited form they took in Sartre's Marxism. The article concludes that Sartre's struggles can be enlightening to those of us who now seek the joyful wisdom of existential freedom for the individual even as we confront the demands that environmental degradation will place on the collective.     

From Canon to Dialectic to Antinomy: Giving Inclinations Their Due

In a recent paper, Eckart Förster challenges interpreters to explain why in the first Critique practical reason has a canon but no dialectic, whereas in the second Critique, there is not only a dialectic, but an antinomy of practical reason. In the Groundwork, Kant claims that there is a natural dialectic with respect to morality (4:405), a different claim from those advanced in the first and second Critiques. Förster's challenge may therefore be reformulated as the problem of explaining why practical reason has a canon in the first Critique, a dialectic in the Groundwork, and an antinomy in the second Critique. In this paper, I answer this challenge. I argue that these differences are due to the different aims and scope of the works, and in particular, the different place of the inclinations in their arguments.     

Target location and visual feedback as variables determining accuracy of aiming movements

The accuracy of a long aiming movement was studied as a function of whether it was performed toward or away from the midline of the subject's body in the presence or absence of visual feedback. 30 right-handed, male university students (19-26 yr.) served as subjects. With movement distance and duration controlled, the mean percentage of error was 6.34% less for movements made toward the body's midline than for those performed away from the midline. The mean percentage of error was also 48% less in the presence of visual feedback than in its absence. However, contrary to our expectation, movements executed toward the body's midline were not appreciably less disrupted in the absence of visual feedback than movements performed away from the midline.     

Painful semantic context modulates the relationship between action words and biological movement perception

Studies have revealed a close relationship between action–word processing and the detection of point-light biological movements and that this effect can be modulated by the context of action-verb presentation. The goal of the present study was to further examine the extent to which motor representation activation plays a role in this relationship by testing the influence of painless/painful sentence understanding during a listening task. Participants judged the presence or absence of a point-light biological movement that was embedded in a scrambled mask after a congruent or incongruent action sentence was presented. The sentences varied according to the context of action-verb presentation (painful, painless). Perceptual judgments of human movements improved after a prior presentation of a congruent action sentence but only in the painless context. Thus, our findings show that pain included in a semantic context of sentence presentation can preclude the relationship between action–word understanding and point-light biological movement judgments.     

Aspects of body self-calibration

The representation of body orientation and configuration is dependent on multiple sources of afferent and efferent information about ongoing and intended patterns of movement and posture. Under normal terrestrial conditions, we feel virtually weightless and we do not perceive the actual forces associated with movement and support of our body. It is during exposure to unusual forces and patterns of sensory feedback during locomotion that computations and mechanisms underlying the ongoing calibration of our body dimensions and movements are revealed. This review discusses the normal mechanisms of our position sense and calibration of our kinaesthetic, visual and auditory sensory systems, and then explores the adaptations that take place to transient Coriolis forces generated during passive body rotation. The latter are very rapid adaptations that allow body movements to become accurate again, even in the absence of visual feedback. Muscle spindle activity interpreted in relation to motor commands and internally modeled reafference is an important component in permitting this adaptation. During voluntary rotary movements of the body, the central nervous system automatically compensates for the Coriolis forces generated by limb movements. This allows accurate control to be maintained without our perceiving the forces generated.     

The locus of adaptation to altered gain in aimed movements

Altered gain settings cause a mismatch between the actual movement amplitude across the surface and the distance covered on a real time visual display. The present study pursued three objectives of how adaptation to altered gain affects aimed motor behavior. First, we replicated findings of an earlier study reporting a negative linear relation between gain and both target acquisition time and end-point variability. This means that our data do not agree with the classic U-shaped relation between gain and acquisition time. Second, our results proved to be robust when we manipulated movement difficulty by varying target distance. And third, dividing a movement into four successive sections on the basis of key kinematic events revealed the locus of the adaptation to altered gain within movement execution. Time differences between gain conditions proved to start at a very early part of the movement, but appeared to be absent in the final movement section. In contrast, differences between gain conditions regarding the use of online feedback were also present in the last part of the movement during which the final target approach takes place.     

The objects of American religious studies

Disciplinary retrospectives on American religious studies have come over the last several decades to center on a single turning point, a decisive and expansive reformation of the object of scholars’ attentions. In a nutshell, somewhere between the 1970s and 1980s a vanguard among us began at last to leave off writing about white, northeastern, Protestant men and to write instead about everybody: more religions, more relations to religion, more of what counts as religion in the first place. Even as it lies at the animating heart of our disciplinary self-appraisals, however, this narrative turn from Protestantism to pluralism in American religious studies seems itself peculiarly resistant to analysis. This essay proposes that we revisit the dialectic between ‘oneness’ and ‘manyness’ in American religious history and historiography. In particular, it urges that we bring scrutiny to bear on the ways that our newer narratives of religious pluralism in America come to be spliced within a more longstanding and resilient metanarrative rooted in American Protestantism.     

Newborns' preference for goal-directed actions

The central role of sensory-motor representations in cognitive functions is almost universally accepted. However, determining the link between motor execution and its sensory counterpart and when, during ontogenesis, this link originates are still under investigation. The aim of the present study is to investigate whether at birth this link is already present and 2-day-old newborns are able to discriminate between visual cues indicating goal-directed or non-goal-directed actions. Here, with a preferential looking technique, a hand grasping a ball was the observed movement and we orthogonally manipulated the three factors necessary to successfully reach the goal: (a) presence of the ball, (b) direction of the arm movement, and (c) hand shaping. Results indicated that newborns orient more frequently and look longer at a hand shape for whole hand prehension but only when the movement is directed away from the body and toward the external world. In addition, newborns prefer the away from the body movement only when the object is present. We argue that newborns prefer a movement directed toward the external world only when it may develop into a purposeful movement because of the presence of the to-be-grasped object. Overall, our results support the existence of primitive sensory-motor associations since the first days after birth.     

Topical Roots of Formal Dialectic

Formal dialectic has its roots in ancient dialectic. We can trace this influence in Charles Hamblin’s book on fallacies, in which he introduced his first formal dialectical systems. Earlier, Paul Lorenzen proposed systems of dialogical logic, which were in fact formal dialectical systems avant la lettre, with roles similar to those of the Greek Questioner and Answerer. In order to make a comparison between ancient dialectic and contemporary formal dialectic, I shall formalize part of the Aristotelian procedure for Academic debates. The resulting system will be compared (1) with Van Eemeren and Grootendorst’s system of rules of Critical Discussion (the pragma-dialectical discussion procedure), which must, however, first itself be reconstructed as a formal dialectical system, and (2) with a Hamblin-type system, and (3) a Lorenzen-type system. When drawing comparisons, it will become clear that there is a line to be drawn from Aristotle to formal dialectic and pragma-dialectics, extending to contemporary computational models of argument.     

Remembering and Remembering to Forget

To navigate our lives we all need to find ways both to remember and sometimes to forget aspects of our experiences that threaten us or cause us anxiety. Often patients need help in developing a capacity to hold in some dialectical tension, both remembering and forgetting. Some people are so frightened by the harsher realities of their lives that they turn to us to take on the remembering side of this dialectic, and, sometimes, to take on the forgetting side. Part of the work of their therapy is to help them develop the capacity to do more of both for themselves. Other patients come better prepared to take on this challenge and use us to witness and support their own efforts. This paper considers how patients use their hours with us to remember and to forget and ways in which psychoanalysts might participate in this undertaking.
