Long‐range correlation is a general class of coordination pattern found to be common to the intrinsic dynamics of complex systems, including human behavior. Balasubramaniam, Hove, and Médé investigate intrinsic dynamics in repeated finger movements, and they find that different measures of movement dynamics yield different long‐range correlations. Results shed light on the way that coordination patterns are expressed as a function of measurement context.

Grush has proposed a fairly comprehensive version of the idea of internal models within the framework of the emulation theory of representation. However, the formulation suffers from assumptions that render such models biologically infeasible. Here I present some problems from physiological principles of human movement production to illustrate why. Some alternative views to emulation are presented.

It is proposed here that Webb's ideas about robots as possible models of animals need some rethinking. In our view, even though widely used biorobotics strategies are fairly successful at reproducing the macroscopic behavior of biological systems, there are still several problems unresolved on the side of robotics as well as biology. Both mathematical and hardware-like robotics models should be feasible physiologically. Control principles elaborated in robotics are not necessarily applied to biological control systems. Although observations of flying birds inspired (...) aerodynamics and thus modern airplanes, little knowledge has been added to the neurophysiological principles underlying flight in birds. Chess playing computers might outperform most chess players, but they cannot be considered as physiologically feasible models of human thinking. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Pains And Gains Of Rural Health Practice:Lessons Books Never TaughtSridevi Seetharam, Bindu Balasubramaniam, G. S. Kumar, and M. R. SeetharamHow The Journey BeganIn the early 1980s, as fresh graduates from Mysore Medical College in southern India, we were brimming with a zeal to "cure the sick" and "change the world." We had an ideal of evidence-based, rational, ethical and equitable health care and set out to serve rural (...) and under-served communities which included displaced forest-based tribes. In the initial years, with the naivety of the inexperienced, we believed that by correcting the dehydration of the doe-eyed six-year-old Mare and giving her a free course of antibiotics, we had made health care accessible to her. Much to our dismay, within a month, Mare was back in the outpatient clinic, with diarrhea all over again and looking thinner than ever. We realized that it was a losing battle to keep her healthy as long as she continued to drink water from the same contaminated stream, live in unhygienic surroundings, and eat only the paltry meals that her family could barely afford. We gradually began to connect these living examples to what our preventive medicine text books had stressed all along—there are many social determinants of health which, if left unaddressed, do not permit realization of the vision of health for all.Such instances continually pulled us out of the hospital building and into the villages and tribal hamlets. We discovered that our textbook of Preventive and Social Medicine (Park, 1986) (P&SM as we used to call it), was our most valuable possession. [End Page 106] We devoured the descriptions of national health programs, sanitation procedures, water treatment protocols, and maintenance of cold chain for vaccines with a completely new perspective. We discovered the Manual of Basic Techniques for a Health Laboratory, (World Health Organization, 1980) detailing how to set up a laboratory with low cost, reliable and simple methods. We learned to drive a jeep to haul supplies and patients. To step up the level of clinical care, some of us pursued post-graduate programs and equipped ourselves to provide more specialized care too. It has been over two decades since we embarked on this journey. We have encountered a variety of perplexing dilemmas with no clear solutions. We have sometimes been compelled to adopt health practices that were not really evidence-based, seemingly irrational, inequitable and even downright unethical. This narration describes only a few of our thousands of cases, and hopefully conveys our periods of self-doubt, despair and hope, as well as, the challenges we face to reconcile with the difficult choices we are forced to make every day.Unforeseen Challenges in Saving Mothers and ChildrenHigh maternal and child mortality rates have been one of the most disturbing aspects of the health care scenario in rural India. To ensure immunization of all children, health workers with vaccine carriers go from village to village and hamlet to hamlet to reach those infants that would have missed visits to the immunization clinics. Our grass-root workers facilitate these visits by identifying households with such children. Occasionally, they encounter families who spirit away the infant into the adjoining woods as soon as the health worker is seen approaching, and blandly proclaim that the child is not at home. Despite reassurance and counseling about the safety and necessity of the vaccine, their apprehensions and misconceptions are insurmountable. What is the extent of the responsibility of the health worker? Is it ethical to hunt down the child and force the administration of the vaccine in view of the public health gains, besides the child's welfare?A few months ago, a pre-term neonate was admitted to our hospital, but worsened and needed referral to a higher centre in the city. The family refused to go despite repeated persuasion and detailed explanation about the technical limitations of care at our centre. From the family's perspective, the variety of social, cultural, and monetary challenges they would face in the city were themselves limitations for care. We were compelled to retain the baby and continue giving the best care we could.Two... (shrink)

The fearful ape hypothesis proposes that heightened fearfulness in humans is adaptive. However, despite its attractive anthropocentric narrative, the evidence presented for greater fearfulness in humans versus other apes is not sufficient to support this claim. Conceptualization, context, and comparison are strongly lacking in Grossmann's proposal, but are key to understanding variation in the fear response among individuals and species.

Rich sensorimotor interaction facilitates language learning and is presumed to ground conceptual representations. Yet empirical support for early stages of embodied word learning is currently lacking. Finding evidence that sensorimotor interaction shapes learned linguistic representations would provide crucial support for embodied language theories. We developed a gamified word learning experiment in virtual reality in which participants learned the names of six novel objects by grasping and manipulating objects with either their left or right hand. Participants then completed a word–color match (...) task in which they were tested on the same six words and objects. Participants were faster to respond to stimuli in the match task when the response hand was compatible with the hand used to interact with the named object, an effect we refer to as affordance compatibility. In two follow up experiments, we found that merely observing virtual hands interact with the objects was sufficient to acquire a smaller affordance compatibility effect, and we found that the compatibility effect was driven primarily by responses with a compatible hand and not by responses in a compatible spatial location. Our results support theoretical views of language which ground word representations in sensorimotor experiences, and they suggest promising future routes to explore the sensorimotor foundations of higher cognition through immersive virtual experiments.

When multiple individuals interact in a conversation or as part of a large crowd, emergent structures and dynamics arise that are behavioral properties of the interacting group rather than of any individual member of that group. Recent work using traditional signal processing techniques and machine learning has demonstrated that global acoustic data recorded from a crowd at a basketball game can be used to classify emergent crowd behavior in terms of the crowd's purported emotional state. We propose that the description (...) of crowd behavior from such global acoustic data could benefit from nonlinear analysis methods derived from dynamical systems theory. Such methods have been used in recent research applying nonlinear methods to audio data extracted from music and group musical interactions. In this work, we used nonlinear analyses to extract features that are relevant to the behavioral interactions that underlie acoustic signals produced by a crowd attending a sporting event. We propose that recurrence dynamics measured from these audio signals via recurrence quantification analysis (RQA) reflect information about the behavioral dynamics of the crowd itself. We analyze these dynamics from acoustic signals recorded from crowds attending basketball games, and that were manually labeled according to the crowds' emotional state across six categories: angry noise, applause, cheer, distraction noise, positive chant, and negative chant. We show that RQA measures are useful to differentiate the emergent acoustic behavioral dynamics between these categories, and can provide insight into the recurrence patterns that underlie crowd interactions.
