Skill transfer,affordances and dexterity in different climbing environments

This study explored how skills in one region of a perceptual-motor landscape of performance, created in part by previous experience in rock climbing, can shape those that emerge in another region (ice climbing). Ten novices in rock climbing and five intermediate rock climbers were observed climbing an icefall. Locations of right and left ice tools and crampons were videotaped from a frontal camera. Inter-individual variability of upper and lower limb couplings and types of action regarding icefall properties were assessed by cluster hierarchical analysis, distinguishing three clusters. Pelvis vertical displacement, duration and number of pelvis pauses were also analyzed. Experienced rock climbers were grouped in the same cluster and showed the highest range and variability of limb angular locations and coordination patterns, the highest vertical displacement and the shortest pelvis plateaux durations. Non-fluent climbers (clusters 2 and 3) showed low range and variability of limb angular locations and coordination patterns. In particular, climbers of cluster 3 exhibited the lowest vertical displacement, the longest plateaux durations and the greatest ratio between tool swinging and definitive anchorage. Our results exemplified the positive influence of skills in rock climbing on ice climbing performance, facilitated by the detection of affordances from environmental properties.     

Sensory substitution: an approach to the experimental study of perception / Sustitución sensorial: un abordaje para el estudio experimental de la percepción

Abstract

Sensory substitution refers to the phenomenon where object and environment information normally acquired through one sense can be obtained by another sense. For example, visual input being provided by hearing or touching. Sensory substitution devices are technological designs that transform the characteristics of one sensory modality into stimuli of another sensory modality. These devices were developed with two purposes: (1) to assist people with sensory disabilities in daily tasks; and (2) to study the involved mechanisms of brain plasticity. This article reviews studies in which sensory substitution phenomenon is employed as a methodological strategy to study visual perception. Furthermore, its use is discussed as an experimental platform to contrast new perceptual theories and underlying neurophysiological mechanisms that are currently under review.     

Re‐framing systemic paradigms for the art of learning

Thoughtful people are increasingly concerned that the current paradigms for social, corporate, and educational activities are in disgraceful disarray. The “problem‐solving” or analytical model, the competitive or game model, the commercial or consumer model, the bureaucratic or institutional model, and the disease or illness model which prevail in public discourse are proving to be especially unwholesome. We cannot, however, educate ourselves without paradigms. A credible educational paradigm must be generally accessible without being simplistic, informative without being monothematic, and accommodating as well as discriminating. Given our disquiet with the current cognitive situation, a renewing paradigm must be somehow novel; given the character of human nature, a sustaining paradigm must be somehow familiar.

For a very long time now, professional Sciences have committed themselves to paradigms about “reality out there,” while professional Arts have devoted themselves to expressing “imagination from within here.” The more these two worldviews polarize in opposition to one another, the more room there is—and the more human heed there becomes—for mediation by an applied philosophy which accommodates the “real” as well as the “imaginary” in a complementary way. Such a philosophy would address not only “what do you know?” and “how do you do?” but also “how do you know?” and “why do you do?” In earlier times, people would have been considered neither educated nor wise unless they appreciated the Sciences and the Arts whole. In our time, we may not survive unless we can re‐integrate our fractured perceptions. How might we proceed to do so? There may be a systemological way.     

Chaotic attractors in the therapeutic system 1

Because little research had been done on the presence and role of latent communication in the context of team‐conducted family therapy, the writers set out to monitor unconscious responses generated under these conditions. Specifically, they investigated an ongoing family treatment situation conducted according to the “reflecting team model.” One team of therapists handles the actual treatment session, while the other observes from behind a one‐way mirror. During the course of a session, the second team makes suggestions to the treatment team either by telephone or by calling the therapists out of the treatment room.

As the project developed, the writers found that the unconscious responses of both family and treatment teams indicated a process at work beyond the conscious intentions of the participants. That is, the therapeutic enterprise was functioning as a dynamical system, whose increasing complexity suggested a self organizing principle at work. This paper traces the development of the system's movement toward greater complexity, identifies the specific interventions that indicate this process, describes how all participants demonstrated a high degree of resonance and synchronization with this overarching‐self organizing pattern. This paper serves to alert therapists to the role of unconscious communication within the therapeutic system and postulates that the generation of form within psychotherapy follows many of the same self organizing processes found in other human and non human systems.     

On the archetypes in information systems development: An exploration

In this paper I examine possible archetypes that embody the role that systems analyst play in different models of systems development and briefly review attendant epistemological and ontological assumptions.     

The demotion of alpha‐homo sapiens: Consciousness,punctuated equilibrium,and the laws of the game

The result of using Eigen and Winkler's LIFE/DEATH GAME to integrate Rashevksy's social physics and Rapoport's mathematical game theory, synchrony removes the arbitrariness from problems of ethics. It focuses on the primary conflicts between strategies that optimize individual survival and those that optimize survival of groups. According to synchrony, cooperation is an optimal strategy, not because cooperation conforms to some ethical pattern, but because the evolution of our technical societies has made the alternatives to cooperation potentially lethal at all levels of human interaction. Eigen and Winkler offer hypercycles as a possible method of resolving problems that conventional wisdom has labeled “irreconcilable differences.”

Combined with the findings of clinical psychologist Paul Meehl and cultural anthropologist Magoroh Maruyama, Eigen and Winkler's LIFE/ DEATH GAME indicates that a pattern of reasoning, called Alpha‐H, is not only a formidable obstacle to cooperation, it threatens contemporary societies with extinction through violent conflicts, social upheavals economic collapse or all three together.

The Demotion of Alpha‐H argues that an inability to deal constructively with change and/or diversity is Alpha‐H's fatal flaw. And the removal of gender bias toward opponent processes reasoning is a crucial step toward correcting it. The key concept is the LIFE/DEATH GAME.     

Canada 2001: Alternative futures for the Canadian communities

The global “problématique humaine” is described in terms of the “grand issues” of population, resources, development in the rich and poor countries, and the environment. Three competing paradigms about the future and their implications for the Canadian communities are examined, and a model is offered showing interrelationships between the different Canadian communities, organizational levels, and various societal/environmental activities. A comprehensive programme of future‐oriented studies is proposed.

This article is a shortened version of a monograph to appear as one of a series entitled Queen's Studies of the Future of the Canadian Communities, published by the Institute of Intergovernmental Relations, Queen's University, Kingston, Ontario. The research was funded by the Donner Canadian Foundation.     

World ethics: Its foundation

Although there are enormous differences between humans, it is also the case that they are fundamentally alike in certain ways. As a prelude to universal ethics, this paper enumerates many commonalities among humans.
