Open peer commentary on the article “Creativity in Solving Short Tasks for Learning Computational Thinking” by Valentina Dagienė, Gerald Futschek & Gabrielė Stupurienė. Abstract: Computational thinking (CT) skills are nowadays strongly advocated for educational institutions at all levels. CT refers broadly to skills of thinking about the world from a computational perspective, however, not necessarily referring to programming skills in particular. There is still a lack of consensus about what CT means, and how CT should be taught. This open peer commentary briefly discusses some ongoing trends of CT in response to the target article, which reports development, field testing and piloting of an extensive set of new learning materials for teaching CT. Recent calls for interdisciplinary technology education, creativity and open-ended problem solving in CT are highlighted.

Proponents of enactivism should be interested in exploring what notion of action best captures the type of action–perception link that the view proposes, such that it covers all the aspects in which our doings constitute and are constituted by our perceiving. This article proposes and defends the thesis that the notion of sensorimotor dependencies is insufficient to account for the reality of human perception and that the central enactive notion should be that of perceptual practices. Sensorimotor enactivism is insufficient because it has no traction on socially dependent perceptions (SDPs), which are essential to the role and significance of perception in our lives. Since the social dimension is a central desideratum in a theory of human perception, enactivism needs a notion that accounts for such an aspect. This article sketches the main features of the Wittgenstein-inspired notion of perceptual practices as the central notion to understand perception. Perception, I claim, is properly understood as woven into a type of social practices that includes food, dance, dress, and music. More specifically, perceptual practices are the enactment of culturally structured, normatively rich techniques of commerce of meaningful multi- and intermodal perceptible material. I argue that perceptual practices explain three central features of SDP: attentional focus, aspects’ salience, and modal-specific harmony-like relations.

Key words: enactivism, perception, practices, culture, intersubjectivity, pragmatism.

In his comment, McGann argues that in my “From Sensorimotor Dependencies to Perceptual Practices: Making Enactivism Social,” I have overlooked a group of enactivist theories that can be grouped under the participatory sense-making label. In this reply, I explain that the omission is due to the fact that such theories are not accounts of perception. It is argued that, unlike participatory sense-making, the approach of the “From Sensorimotor Dependencies to Perceptual Practices” article does not focus on the perceptual aspects of things social, but on the social aspects that are constitutive of perception in general. I conclude by underscoring the central argument of the original article: that the adequate notion to make enactivism about perception social is that of “perceptual practices,” a social practices-based notion of perception.

Context: Although trauma research has advanced immensely, the struggle to find effective treatment for posttraumatic survivors continues. It seems reasonable to say that, at present, our ability to treat those suffering from posttraumatic stress disorder (PTSD) is, at the very least, limited. Problem: We argue that in order to confront the current crisis in the study of trauma - evidenced by our limited ability to offer successful treatment for those who develop PTSD - we must return to the subjective experience. Our claim is that only by applying a rigorous method to study the subjective experience will we be able to understand the meaning of neuronal activity associated with PTSD. Method: The neurophenomenological research program (NRP) is a working plan that enables us to create a solid and reliable link between the subjective experience and neuronal activity. Thus, the NRP allows us to (a) delve deeply (and rigorously) into the subjective experience and, by so doing, (b) extract the cognitive mechanism that constitutes the building blocks bridging between the subjective experience and neuronal activity. Following this, we will be able to (c) identify the relevant neuronal activity for the phenomenon under examination. Results: Based on previous studies among posttraumatic survivors, we suggest that two cognitive mechanisms are especially relevant for the study of trauma: the sense of body ownership (i.e., the sense that this is our own body) and the sense of agency (the sense that we control our body. The trade-off between these closely related, yet independent mechanisms is highly significant. We conclude the article with the presentation of a detailed working plan for the study of trauma - one that begins with the subject and returns to the subject. Implications: This article summarizes our struggle to conduct a phenomenological research in the study of trauma and our methodological efforts of the last ten years. It should help the beginner to avoid some mistakes that have been made in this long journey, yet obviously, each one must build their own route. Likewise, we suggest that phenomenologists, brain scientists and clinicians should find a way to cooperate. This shared effort might allow us to improve our understanding of the traumatic experience and its long-term implications; as such, we believe that in this process a better treatment could be developed. That being said, the limitation of our proposal is the difficulty of creating a shared language that bridges these different worlds. Constructivist content: We strongly embraces phenomenological approach together with enactivist/embodied theories.

Abstract: This response confronts some crucial questions raised by the reviewers: (a) Can the phenomenological approach be applied to the study of trauma? (b) What is the exact meaning of the term “traumatic event? (c) Is our phenomenological approach too thin? (d) What is the nature of the proposed cognitive bridge - what else is needed? (e) Is the shared world indeed lacking? (f) Is it possible to control patients with posttraumatic stress disorder in the lab? (g) How is our proposal innovative?

This article presents a unifying theory of the embodied, situated human brain called the Hierarchically Mechanistic Mind (HMM). The HMM describes the brain as a complex adaptive system that actively minimises the decay of our sensory and physical states by producing self-fulfilling action-perception cycles via dynamical interactions between hierarchically organised neurocognitive mechanisms. This theory synthesises the free-energy principle (FEP) in neuroscience with an evolutionary systems theory of psychology that explains our brains, minds, and behaviour by appealing to Tinbergen’s four questions: adaptation, phylogeny, ontogeny, and mechanism. After leveraging the FEP to formally define the HMM across different spatiotemporal scales, we conclude by exploring its implications for theorising and research in the sciences of the mind and behaviour.

Open peer commentary on the article “Problematizing: The Lived Journey of a Group of Students Doing Mathematics” by Robyn Gandell & Jean-François Maheux. Abstract: The aim of this commentary is to add to the conceptualization of problematizing by prompting a consideration of the teacher-observer as a wholly complicit, ethical participant in the mathematical journeys of their students.

Context: For many people, religion and/or spiritual experiences are an important part of their daily lives - shaping their thinking and actions. Studying these experiences relies on qualitative religious studies (RS) research that engages respondents on a deeply personal level. Problem: Researchers are unable to provide an apolitical, value-free approach to research. There lacks a rigorous methodological approach to qualitative RS research that addresses this epistemological obstacle. This is particularly relevant when studying a cohort with radically different beliefs from the researcher. Method: Researcher coupling is presented as a topic that defines the researcher and her participants as a systemic entity. By demonstrating how the researcher’s worldview is tied to her research, an argument for personalised and relational observer-dependent research is presented. Five reflexive questions are proposed as a starting point for personalised research to demonstrate the relational and intersubjective nature of this activity. Results: By linking the researcher to her research and changing the goal of research from independent and objective research to one that is relational and contextual, the scholar can report on her research in an ethical and socially just manner by linking her worldview to her research. Implications: The traditional research activity is redefined as one that should embrace the scholar’s worldview instead of attempting to hide it. The scientific ideals of independence and objectivity are replaced by interdependence and hence a proposal is made for personalised research that embraces the intersubjective nature of this activity. This proposal is meant to alleviate some of the epistemological weaknesses in RS. This paradigm shift promotes rigour as a qualifier for methodology including changes to how research is categorised. Constructivist content: Margaret Mead’s ideas of observer dependence in anthropological research and how the observer constructs her research findings are discussed. The circularity that exists in this relational context is analysed according to Bradford Keeney’s ideas on recursion and resultant future behavioural correction. Ranulph Glanville’s ideas of intersubjectivity and his concept of “in the between” are used as a foundation for the researcher-participant relationship. Ross Ashby’s notion of experimenter coupling is used as a basis for researcher coupling.

Abstract: Ultimate truths and dogma form part of many religions, which poses epistemological challenges to researchers who have differing beliefs yet wish to study these religions. I have argued that conceptual bridging is a prerequisite in meeting this challenge as religious studies scholars should have a deep knowledge base of a variety of belief systems to assist in conceptualising the believers’ world. Scholars, however, need to be comfortable hearing the truths of others, which at times may be contrary to their own worldviews.

The notion of structural coupling plays a central role in Maturana and Varela’s biology of cognition framework and strongly influenced Varela’s subsequent enactive elaboration of this framework. Building upon previous work using a glider in the Game of Life (GoL) cellular automaton as a toy model of a minimal autopoietic system with which to concretely explore these theoretical frameworks, this article presents an analysis of structural coupling between a glider and its environment. Specifically, for sufficiently small GoL universes, we completely characterize the nonautonomous dynamics of both a glider and its environment in terms of interaction graphs, derive the set of possible glider lives determined by the mutual constraints between these interaction graphs, and show how such lives are embedded in the state transition graph of the entire GoL universe.
