Variations on the vertical jump: individual adaptations to changing task demands

Here we explored the coordination of joint behaviors exhibited during the vertical jump and variations of that jump. By manipulating the take-off angle, we required an adjustment to changing task demands. It was hypothesized that kinematic features of the jump would change but that spatiotemporal relationships essential to propulsion would remain invariant across all conditions. To test this hypothesis, six adult male subjects performed jumps at six different take-off angles. An analysis of cinematographic data revealed that individual subjects changed the sequence and timing of lower-extremity joint reversals. In contrast, the covariation of joint behaviors during the propulsive phase and the timing of maximum intersegmental extension velocities were extremely stable within each individual across changes in task. We argue that the flexibility to alter sequence and timing is part of a strategy that permits adaptation to the context and facilitates a continued coordination among variables associated with propulsion.     

Finer Distinctions: Variability in Satisfied Older Couples’ Problem‐Solving Behaviors

This study utilized observational and self‐report data from 64 maritally satisfied and stable older couples to explore if there were meaningful differences in how couples approached marital disagreements. Using a typology approach to classify couples based on their behaviors in a 15‐minute problem‐solving interaction, findings revealed four types of couples: (1) problem solvers (characterized by both spouses’ higher problem‐solving skills and warmth), (2) supporters (characterized by both spouses’ notable warmth), (3) even couples (characterized by both spouses’ moderate problem‐solving skills and warmth), and (4) cool couples (characterized by both spouses’ greater negativity and lower problem‐solving skills and warmth). Despite the differences in these behaviors, all couples had relatively high marital satisfaction and functioning. However, across nearly all indices, spouses in the cool couple cluster reported poorer marital functioning, particularly when compared to the problem solvers and supporters. These findings suggest that even modest doses of negativity (e.g., eye roll) may be problematic for some satisfied couples later in life. The implications of these typologies are discussed as they pertain to practitioners’ efforts to tailor their approaches to a wider swath of the population.     

Motor intentionality and the case of Schneider

I argue that Merleau-Ponty’s use of the case of Schneider in his arguments for the existence of non-conconceptual and non-representational motor intentionality contains a problematic methodological ambiguity. Motor intentionality is both to be revealed by its perspicuous preservation and by its contrastive impairment in one and the same case. To resolve the resulting contradiction I suggest we emphasize the second of Merleau-Ponty’s two lines of argument. I argue that this interpretation is the one in best accordance both with Merleau-Ponty’s general methodology and with the empirical case of Schneider as it was described by Gelb and Goldstein.

Word of God or Witness? Issues in Christian Biblical Hermeneutics

This article gives a historical overview of the main issues and problems facing Christian interpreters of the Bible. The Christian understanding of the Bible is influenced by two main factors. On the one hand, Christians believe that God revealed himself and was present in the life, ministry, teaching, death and resurrection of Jesus of Nazareth. In other words, Jesus is the one Word of God. On the other hand, Christians believe that the Bible is inspired Holy Scripture, containing the revelation of God. There is a tension between these two approaches, as one locates the divine revelation in the person of Jesus of Nazareth, the other in the Holy Book. The article argues that this tension has been a major creative driving force in the history of Christian biblical interpretation. It traces the main strategies with which Christian interpreters have approached the Bible in order to reconcile these two elements, or in which they have allowed one to overrule the other. This will provide an introduction to the key approaches and methods in Christian biblical interpretation.     

Conceptions of God and the Devil Across the Lifespan: A Cultural-Developmental Study of Religious Liberals and Conservatives

Utilizing a cultural-developmental approach, this interview study examined how children, adolescents, and adults from religiously liberal and conservative groups conceptualize God and the Devil. Participants ( N = 120) conceptualized God and the Devil along similar dimensions, including number (e.g., one, many), gender, central attributes (e.g., physical, supernatural), and evaluation (e.g., positive, neutral). Within-subject differentiations of God and the Devil occurred on all dimensions. Religiously liberal and conservative groups differed on attributes, evaluations, and degree of control ascribed to God and the Devil. With respect to age, results suggest a rethinking of the Piagetian interpretation that children's conceptions of supernatural entities are more concrete, more anthropomorphic, and less abstract than those of adolescents and adults. The results instead point to the usefulness of a cultural-developmental approach.     

Developing/development cyborgs

The paper takes as its starting point Donna Haraway’s suggestion, “The actors are cyborg, nature is coyote, and the geography is elsewhere”. It discusses first the understanding of the cyborg promoted by Haraway as illustrating an ontological non-humanist disposition, rather than a periodizing claim. The second part of the paper examines some instances of low-tech cyborg identities, which have emerged in developing countries (elsewhere) as a consequence of development initiatives. The paper argues that the quite literal attempts to develop cyborgs in such countries gives rise to developments not foreseen or controllable by the development industries. If cyborg identities are developing and minds and bodies shaped in the frictions between culture, technology, economy, and development projects and activities then what are the implications for cognitive studies. In the final part of the paper this question is considered and it is suggested that cognitive studies would do well to expand their analytical foci to take into account cyborg bodies and minds found “elsewhere”.
