RESUMEN

Ecological and enactive approaches to embodied cognition endorse a concept of constitution that involves dynamical causality. I argue that this is a challenge for new mechanistic accounts which hold to a strict distinction between causality and constitution.

RESUMEN

Although post-cognitivist approaches have shaken the status quo by emphasising the dynamic interactions among the brain, the body, and the environment in cognition, mainstream psychological theories continue to view concepts as primarily representational or skull-bound mental phenomena. As a result, the dynamics of action and the possible impact of material culture on conceptual thinking are poorly understood. In this paper, we explore the process and meaning of conceptual thinking from a material engagement perspective. We argue that conceptual thinking is not a matter of forming representations in the head but something we do-a way of engaging with materiality. Conceptual thinking is conceptual thinging, namely a kind of unmediated practical knowledge that individuals put into play when they engage, in a general way, with and through the world. In this sense, we propose that conceptual thinking is instantiated in the dynamic coordination of bodily practices and artefacts in sociomaterial activities. To elucidate this perspective, we introduce seven principles defining conceptual thinking within an ecological-enactive framework of cognition.

RESUMEN

INTRODUCTION: Reduced physical activity (PA) among people with multiple sclerosis (pwMS) with low disability is a significant concern. Developing healthcare to promote PA requires a comprehensive understanding of pwMS's perspectives. PURPOSE: To explore how pwMS with mild disability perceive PA and the impact of individual, professional, social, and environmental aspects on their PA engagement. METHODS: Qualitative, in-depth interviews with 27 pwMS (21 women, 6 men; aged 31-66; EDSS ≤ 3.5) were analyzed via systematic text condensation and informed by enactive theory. RESULTS: Three categories were formed: Perception Shifts after Diagnosis: Participants adapted their perceptions to PA throughout their disease journey. Initial uncertainty concerning bodily capacities, prospects and safety reduced PA. Moving "correctly" during activities was emphasized to facilitate PA levels. Affective Experiences Drive Behavior: Pleasure associated with movement was a highlighted motivator, however, some experienced PA less rewarding after diagnosis. Discomfort and fear were barriers to PA engagement. The Surroundings Influence Perceptions: Participants sought social interactions and outdoor-environments to improve PA. Healthcare professionals were trusted to provide possibilities for PA, but early-stage and tailored follow-up was often lacking. CONCLUSION: This study illuminates changed PA perceptions after MS diagnosis and how affect, shaped by personal, interpersonal, and environmental aspects, drive PA engagement. Moreover, it calls for early follow-up and the implementation of tailored healthcare throughout the disease course to promote PA engagement. Considering these findings, we have put forth a model aimed at fostering a nuanced comprehension of PA in pwMS with mild disabilities. Further development and exploration of this model is needed.

RESUMEN

Mental disorders are increasingly understood as involving complex alterations of self that emerge from dynamical interactions of constituent elements, including cognitive, bodily, affective, social, narrative, cultural and normative aspects and processes. An account of self that supports this view is the pattern theory of self (PTS). The PTS is a non-reductive account of the self, consistent with both embodied-enactive cognition and phenomenological psychopathology; it foregrounds the multi-dimensionality of subjects, stressing situated embodiment and intersubjective processes in the formation of the self-pattern. Indications in the literature already demonstrate the viability of the PTS for formulating an alternative methodology to better understand the lived experience of those suffering mental disorders and to guide mental health research more generally. This article develops a flexible methodological framework that front-loads the self-pattern into a minimally structured phenomenological interview. We call this framework 'Examination of Self Patterns' (ESP). The ESP is unconstrained by internalist or externalist assumptions about mind and is flexibly guided by person-specific interpretations rather than pre-determined diagnostic categories. We suggest this approach is advantageous for tackling the inherent complexity of mental health, the clinical protocols and the requirements of research.

RESUMEN

Photoluminescence intermittency remains one of the biggest challenges in realizing perovskite quantum dots (QDs) as scalable single photon emitters. We compare CsPbBr3 QDs capped with different ligands, lecithin, and a combination of oleic acid and oleylamine, to elucidate the role of surface chemistry on photoluminescence intermittency. We employ widefield photoluminescence microscopy to sample the blinking behavior of hundreds of QDs. Using change point analysis, we achieve the robust classification of blinking trajectories, and we analyze representative distributions from large numbers of QDs (Nlecithin = 1308, Noleic acid/oleylamine = 1317). We find that lecithin suppresses blinking in CsPbBr3 QDs compared with oleic acid/oleylamine. Under common experimental conditions, lecithin-capped QDs are 7.5 times more likely to be nonblinking and spend 2.5 times longer in their most emissive state, despite both QDs having nearly identical solution photoluminescence quantum yields. We measure photoluminescence as a function of dilution and show that the differences between lecithin and oleic acid/oleylamine capping emerge at low concentrations during preparation for single particle experiments. From experiment and first-principles calculations, we attribute the differences in lecithin and oleic acid/oleylamine performance to differences in their ligand binding equilibria. Consistent with our experimental data, density functional theory calculations suggest a stronger binding affinity of lecithin to the QD surface compared to oleic acid/oleylamine, implying a reduced likelihood of ligand desorption during dilution. These results suggest that using more tightly binding ligands is a necessity for surface passivation and, consequently, blinking reduction in perovskite QDs used for single particle and quantum light experiments.

RESUMEN

Concepts of empathy, sympathy and compassion are often confused in a variety of literatures. This article proposes a pattern-theoretic approach to distinguishing compassion from empathy and sympathy. Drawing on psychology, Western philosophy, affective neuroscience, and contemplative science, we clarify the nature of compassion as a specific pattern of dynamically related factors that include physiological, cognitive, and affective processes, relational/intersubjective processes, and motivational/action tendencies. We also show that the dynamic nature of the compassion pattern is reflected in neuroscientific findings, as well as in compassion practice. The pattern theory of compassion allows us to make several clear distinctions between compassion, empathy, and sympathy.

RESUMEN

AIM: To explore patients' experiences with early rehabilitation in the intensive care unit and what they perceive to influence their participation. DESIGN: A qualitative design anchored in phenomenological and hermeneutical traditions utilizing in-depth interviews. METHODS: Thirteen patients were interviewed from 5 to 29 weeks following discharge from three units, in January-December 2022. Analysed using systematic text condensation and the pattern theory of self. Reporting adhered to consolidated criteria for reporting qualitative research. RESULTS: Interviews described four main categories: (1) A foreign body, how the participants experienced their dysfunctional and different looking bodies. (2) From crisis to reorientation, the transformation the participants experienced from a state of crisis to acceptance and the ability to look forwards, indicating how bodily dysfunctions are interlinked to breakdowns of the patients' selves and the reorganization process. (3) Diverse expectations regarding activity: ambiguous expectations communicated by the nurses. (4) Nurse-patient: a powerful interaction, highlighting the essential significance of positive expectations and tailored bodily and verbal interaction for rebuilding the patient's outwards orientation. CONCLUSION: Outwards orientation and reorganization of the self through a reduction in bodily dysfunctions, strengthening the patients' acceptance of the situation, providing tailored expectations and hands-on and verbal interaction appear to be fundamental aspects of patient participation in early rehabilitation. IMPLICATIONS: Insights into patients' perceptions show how dysfunctional bodies cloud individuals' perceptual fields, causing inwards orientation and negative thoughts concerning themselves, their capabilities, environment and future. This knowledge can improve nurses' ability to tailor care to promote optimal recovery for patients. PATIENT OR PUBLIC CONTRIBUTION: User representative contributed to the design of the study.

RESUMEN

Solution-processed semiconductors are in demand for present and next-generation optoelectronic technologies ranging from displays to quantum light sources because of their scalability and ease of integration into devices with diverse form factors. One of the central requirements for semiconductors used in these applications is a narrow photoluminescence (PL) line width. Narrow emission line widths are needed to ensure both color and single-photon purity, raising the question of what design rules are needed to obtain narrow emission from semiconductors made in solution. In this review, we first examine the requirements for colloidal emitters for a variety of applications including light-emitting diodes, photodetectors, lasers, and quantum information science. Next, we will delve into the sources of spectral broadening, including "homogeneous" broadening from dynamical broadening mechanisms in single-particle spectra, heterogeneous broadening from static structural differences in ensemble spectra, and spectral diffusion. Then, we compare the current state of the art in terms of emission line width for a variety of colloidal materials including II-VI quantum dots (QDs) and nanoplatelets, III-V QDs, alloyed QDs, metal-halide perovskites including nanocrystals and 2D structures, doped nanocrystals, and, finally, as a point of comparison, organic molecules. We end with some conclusions and connections, including an outline of promising paths forward.

RESUMEN

This article aims to show that there is an alternative way to explain human action with respect to the bottlenecks of the psychology of decision making. The empirical study of human behaviour from mid-20th century to date has mainly developed by looking at a normative model of decision making. In particular Subjective Expected Utility (SEU) decision making, which stems from the subjective expected utility theory of Savage (1954) that itself extended the analysis by Von Neumann and Morgenstern (1944). On this view, the cognitive psychology of decision making precisely reflects the conceptual structure of formal decision theory. This article shows that there is an alternative way to understand decision making by recovering Newell and Simon's account of problem solving, developed in the framework of bounded rationality, and inserting it into the more recent research program of embodied cognition. Herbert Simon emphasized the importance of problem solving and differentiated it from decision making, which he considered a phase downstream of the former. Moreover according to Simon the centre of gravity of the rationality of the action lies in the ability to adapt. And the centre of gravity of adaptation is not so much in the internal environment of the actor as in the pragmatic external environment. The behaviour adapts to external purposes and reveals those characteristics of the system that limit its adaptation. According to Simon (1981), in fact, environmental feedback is the most effective factor in modelling human actions in solving a problem. In addition, his notion of problem space signifies the possible situations to be searched in order to find that situation which corresponds to the solution. Using the language of embodied cognition, the notion of problem space is about the possible solutions that are enacted in relation to environmental affordances. The correspondence between action and the solution of a problem conceptually bypasses the analytic phase of the decision and limits the role of symbolic representation. In solving any problem, the search for the solution corresponds to acting in ways that involve recursive feedback processes leading up to the final action. From this point of view, the new term enactive problem solving summarizes this fusion between bounded and embodied cognition. That problem solving involves bounded cognition means that it is through the problem solver's enactive interaction with environmental affordances, and especially social affordances that it is possible to construct the processes required for arriving at a solution. Lastly the concept of enactive problem solving is also able to explain the mechanisms underlying the adaptive heuristics of rational ecology. Its adaptive function is effective both in practical and motor tasks as well as in abstract and symbolic ones.

RESUMEN

Clinical and neuroscientific evidence indicates that transdiagnostic processes contribute to the generation and maintenance of psychopathological symptoms and disorders. Rigidity (inflexibility) appears a core feature of most transdiagnostic pathological processes. Decreasing rigidity may prove important to restore and maintain mental health. One of the primary domains in which rigidity and flexibility plays a role concerns the self. We adopt the pattern theory of self (PTS) for a working definition of self. This incorporates the pluralist view on self as constituted by multiple aspects or processes, understood to constitute a self-pattern, i.e. processes organized in non-linear dynamical relations across a number of time scales. The use of mindfulness meditation in the format of Mindfulness Based Interventions (MBIs) has been developed over four decades in Clinical Psychology. MBIs are promising as evidence-based treatments, shown to be equivalent to gold-standard treatments and superior to specific active controls in several randomized controlled trials. Notably, MBIs have been shown to target transdiagnostic symptoms. Given the hypothesized central role of rigid, habitual self-patterns in psychopathology, PTS offers a useful frame to understand how mindfulness may be beneficial in decreasing inflexibility. We discuss the evidence that mindfulness can alter the psychological and behavioral expression of individual aspects of the self-pattern, as well as favour change in the self-pattern as a whole gestalt. We discuss neuroscientific research on how the phenomenology of the self (pattern) is reflected in associated cortical networks and meditation-related alterations in cortical networks. Creating a synergy between these two aspects can increase understanding of psychopathological processes and improve diagnostic and therapeutic options.

RESUMEN

The concept of minimal self-consciousness or "minimal self" is equivalent to a very basic form of first-person, pre-reflective self-awareness, which includes bodily self-awareness, and is related to phenomenal experience (qualia) and sentience. This phenomenological concept plays a role in characterizations of the senses of ownership and agency; in recent debates about Buddhist conceptions of the no-self; in explanations of illusions such as the Rubber Hand Illusion; as well as in characterizations of schizophrenia as a self-disorder. Despite its relevance to these complex investigations, a number of theorists have recently pointed out that the concept is not well defined. In order to provide some clarification about the notion of minimal self and how it relates to bodily and sensory processes this paper reaches back to the ideas expressed in a famous medieval thought experiment proposed in the 11th century: Avicenna's Flying Man argument. The paper then provides a review of some of the contemporary debates about the minimal self, pointing especially to questions about the role of bodily and social processes.

RESUMEN

In this paper I examine a set of exceptional aesthetic experiences that remove us from our pragmatic everyday life and involve a specific type of unaffordability. I then extend this notion of unaffordability to experiences of awe and its relation to the sublime. My analysis is guided by considerations of the phenomenologically inspired enactivist approach that supports an affordance-based accounts of aesthetic experience. I review some recent neurophenomenological studies of the experience of awe, and I then sketch out a phenomenology of awe as it approaches the sublime.

RESUMEN

In this paper I address what has been called the integration problem in psychiatry. This problem is tied to conceptions of causality and explanatory levels in our understanding of mind. I take an interdisciplinary enactive perspective to develop a 3-fold method for exploring the dynamics of integration, based on a concept of dynamical causation and a non-hierarchical (level-free) notion of gestalt. I also consider Autism Spectrum Disorder (ASD) as a test case.

RESUMEN

Criminal justice liaison and diversion services identify people with mental health needs and ensure they receive appropriate support. We describe a 25-year period of one such service that deals with a population of 864,540 in South East London that was set up in 1991. We used data from three time periods. A diagnosis of a mental illness was recorded in 70.0-80.3% of court liaison and diversion referrals. The proportion receiving a hospital order declined from 15.4% in 1991/1992 to 1.1% in 2015/2016; 54/199 (27.1%) of referrals to the police liaison and diversion service were detained in hospital. Although the service is designed to support any individual with a mental health issue, these results suggest that it has dealt mainly with people who have severe mental illness. Further research is required to understand how best to benefit a wider range of people with mental health issues who attend the lower (Magistrates') courts, and whether screening for mental disorders can be applied in liaison and diversion settings to aid the implementation of national policy. We also need to understand how disposal decisions are made, and which are most effective.

RESUMEN

As easy-to-grow quantum wells with narrow excitonic features at room temperature, two-dimensional (2D) Ruddleson-Popper perovskites are promising for realizing novel nanophotonic devices based on exciton-photon interactions. Here, we demonstrate a distinct hybrid exciton-photon Fano resonance in (C4H9NH3)2PbI4 thin films prepared via spin coating. Using a classical coupled-oscillator model and finite-difference time-domain simulations, we link the Fano interference to the coupling of the exciton with the Rayleigh-like scattering of the film microstructure. Combining colloidal plasmonic cavities with the 2D perovskite films, we demonstrate tuning of the Fano resonance. In combination with silver nanoparticles, the exciton-photon Fano interference couples to the in-plane plasmonic modes with indications of Rabi splitting. By creating a nanoparticle on mirror geometry, we address the out-of-plane excitonic component, reaching an intermediate coupling regime. These structures suggest possible photonic targets for biomolecular self-assembly applications.

RESUMEN

This paper discusses different frameworks for understanding imagination and metaphor in the context of research on the imaginative skills of children with autism spectrum disorder (ASD). In contrast to a standard linguistic framework, it advances an embodied and enactive account of imagination and metaphor. The paper describes a case study from a systemic therapeutic session with a child with ASD that makes use of metaphors. It concludes by outlining some theoretical insights into the imaginative skills of children with ASD that follow from taking the embodied-enactive perspective and proposes suggestions for interactive interventions to further enhance imaginative skills and metaphor understanding in children with ASD.

RESUMEN

Background: Group-based physiotherapy is effective for individuals with MS; nevertheless individualization within groups is questioned and little is known regarding individuals´ experiences with individualization in small groups.Objective: We aimed to explore the short- and long-term experiences of individuals with MS participating in a 6-week, group-based, individualized physiotherapy-intervention.Methods: Within a randomized controlled trial (RCT), 25 in-depth interviews with a strategic sample of 13 people (9 women; age 25-79 years old; European Disability Status Scale (EDSS) 1-6.5) were conducted at weeks 7 and 30 using systematic text condensation, with dynamic systems theory and phenomenology as analytical frameworks.Results: The main categories were: 1) movement control, orientation and insights: Bodily improvements were associated with targeted exercises, specific adjustments by the physiotherapist, emotional engagement and re-access to activities; and 2) the individual within the group: Equal distributions of one-to-one interactions and attention were important for experiencing success. Less attention and improvements turned attention toward own disability. Physical changes felt particularly emotional short term, implying that individuals' feelings of ownership and control of body and movement, new views of themselves and changed affordances in daily life were involved.Conclusion: Equally distributed attention and engagement, targeted exercises and hands-on adjustments resulting in visible and perceived bodily changes were experienced as key factors of individualization in small groups.

RESUMEN

In this paper, we engage in a reciprocal analysis of situated cognition and the notion of "meshed architecture" as found in performance studies (Christensen et al., 2016). We start with an account of various conceptions of situated cognition using the distinction between functional integration, which characterizes how an agent dynamically organizes to couple with its environment, and task dependency, which specifies various constraints and structures imposed by the environment (see Slors, 2019). We then exploit the concept of a meshed architecture as a model that provides a more focused analysis of situated cognition and performance. Through this analysis, we show how the model of meshed architecture can be enhanced through (1) the involvement of a more complex set of cognitive processes, (2) a form of intrinsic control, (3) the influence of affective factors, and (4) the role of factors external to the performer. The aim of this paper, then, is twofold: first to work out an enhanced conception of the model of meshed architecture by taking into consideration a number of factors that clarify its situated nature, and second, to use this model to provide a richer and more definitive understanding of the meaning of situated cognition. Thus, we argue that this reciprocal analysis gives us a very productive way to think about how various elements come together in skilled action and performance but also a detailed way to characterize situated cognition.
