The Idiosyncrasy Principle: A New Look at Qualia

In the study of consciousness, qualia, the individual subjective experience, is neglected. It remains impenetrable because the objective perspective used for scientific investigations misses its subjective nature. In 1974, Thomas Nagel suggested that studying qualia requires an “objective phenomenology method” whose goal would be to describe the subjective character of experiences in an independent manner. We introduce a corresponding theoretical and experimental framework based on the “idiosyncrasy principle.” Accordingly, subjectivity depends on the idiosyncratic composition of physical properties to qualia. This allows conceptualizing an idiosyncratic transfer function between the world and its representation. The main challenge in delineating such a transfer function is to come up with an objective measure for another person’s perspective. Numerosity, as opposed to other perceived contents of the physical world, allows reporting subjective experience in an objective manner. On the basis of this unique attribute of numerosity, we suggest a tentative neurocognitive research plan aimed at delineating such idiosyncratic transfer functions, permitting one person to adopt the perspective of another and linking qualia to its mechanism.

A Systematic Review of Individual Differences in Perception, Action, and Decision Making: Implications for Dance Education.

This systematic bibliometric review summarizes recent neurocognitive research highlighting inter-individual differences in perception, action, and decision making that may have implications for dance education. First, the relevance of individual differences in cognitive functioning for dance education is illustrated by describing how a person's preferred reliance on certain perceptual, motor, or (meta) cognitive skills may be exploited in dance training. Subsequently, we describe the findings of a literature search conducted to identify cognitive neuroscientific publications between 2010 and 2021 that highlight individual differences in cognitive functions that were also found to be supported by structural or functional-connectivity differences in the central nervous system. To cluster the findings of the literature search, we propose a simplified, six-category information processing model. Finally, for each model category, we summarize recent representative findings on salient individual differences and tentatively formulate testable implications for dance education practice with regard to pedagogical and curricula adaptations. Finally, the review also delineates an agenda for lines of research of which the results hopefully will assist dance instructors in the future.

Norms for pictures of proper names: contrasting famous people and well-known places in younger and older adults.

Proper names comprise a class of labels that arbitrarily nominate specific entities, such as people and places. Compared to common nouns, retrieving proper names is more challenging. Thus, they constitute good alternative semantic categories for psycholinguistic and neurocognitive research and intervention. The ability to retrieve proper names is known to decrease with aging. Likewise, their retrieval may differ across their different categories (e.g., people and places) given their specific associated knowledge. Therefore, proper names' stimuli require careful selection due to their high dependence on prior experiences. Notably, normative datasets for pictures of proper names are scarce and hardly have considered the influence of aging and categories. The current study established culturally adapted norms for proper names' pictures (N = 80) from an adult sample (N = 107), in psycholinguistic measures (naming and categorization scores) and evaluative dimensions (fame, familiarity, distinctiveness, arousal, and representational quality). These norms were contrasted across different categories (famous people and well-known places) and age groups (younger and older adults). Additionally, the correlations between all variables were examined. Proper names' pictures were named and categorized above chance and overall rated as familiar, famous, distinctive, and of high representational quality. Age effects were observed across all variables, except familiarity. Category effects were occasionally observed. Finally, the correlations between the psycholinguistic measures and all rated dimensions suggest the relevance of controlling for these dimensions when assessing naming abilities. The current norms provide a relevant aging-adapted dataset that is publicly available for research and intervention purposes.

Self-regulation in preschool: Are executive function and effortful control overlapping constructs?

The concepts of executive function (EF) and effortful control (EC) are strikingly similar. EF originate from neurocognitive research and are described as an accumulation of cognitive processes that serve the goal-oriented self-regulation (SR) of an individual. EC originates from temperament research and is defined as the efficiency of executive attention, including the ability to inhibit a dominant response, to activate a subdominant response, to proceed in a planned manner and to recognize conflicts or errors. The aim of this article was to examine the association between the constructs of EF and EC at the preschool-age. Eighty-eight children (49 female; M-age=3.93 years, SD=.78) were tested with a computerized battery designed to assess EF at 3-6 years of age (EF Touch). Children's parents completed questionnaires assessing EF impairments (BRIEF-P) and EC (CBQ). Associations between the constructs and their conceptual overlap were analyzed using correlations and confirmatory factor analyses. We found significant correlations between EF and EC measures. A one-factor confirmatory model fitted the data very well and indicated that EF and EC are indeed overlapping and highly similar constructs. Therefore, our results show that measures of EC and EF have substantial overlap in preschoolers and suggest an integrated model of self-regulation.

Neural network involvement for religious experiences in worship measured by EEG microstate analysis

ABSTRACT Not much is known about large-scale brain activation patterns in religious states of mind and previous studies have not set an emphasis on experience. The present study investigated the phenomenon of religious experiences through microstate analysis, and it was the first neurocognitive research to tackle the dimension of experience directly. Hence, a total of 60 evangelical Christians participated in an experiment where they were asked to engage in worship and try to connect with God. With a bar slider, people were able to continuously rate how strongly they sensed God’s presence at any given moment. A selection of songs was used to help in the induction of the desired experience. With 64 electroencephalography (EEG) electrodes, the brain activity was assessed and analyzed with five clusters of microstate classes. First, we hypothesized that the neural network for multisensory integration was involved in the religious experience. Second, we hypothesized that the same was true for the Default Mode Network (DMN). Our results suggested an association between the auditory network and the religious experience, and an association with the salience network as well as with the DMN. No associations with the network thought to be involved with multisensory integration was detected.

Meditation, Idealism and Materiality: Vivid Visualization in the Buddhist \u2018Qizil Yoga Manual\u2019 and the Context of Caves

This paper examines the topic of Yogācāra idealism through a little studied Buddhist meditation manual, the so-called ‘Yogalehrbuch’ or ‘Qizil Yoga Manual’, a primarily Buddhist Sarvāstivāda Abhidharma text with Mahāyāna Yogācāra strands. What does this unique Central Asian text say about Buddhist meditation practices called yogācāra or yoga? It centres on methods of vivid visualization that are somewhat specific to the Central Asian region of Kucha on the Silk Road. To understand the Manual’s practice and definition of yogic meditation, this paper considers how some of the hyper-real visualizations in the dhātuprayoga section relate the mind to reality and whether Yogācāra meditation can be said to propose idealism as a metaphysical theory about the nature of reality. The paper also asks whether neurocognitive research insights can be useful in understanding what some regard as a ‘hallucination-like’ quality of some visualizations, which destabilise distinctions between appearances and reality. Furthermore, it argues that analyzing the materiality of meditation, particularly the environment of the cave, helps us to better understand the text’s techniques of yogic visualization. The paper concludes that the ‘Qizil Yoga Manual’ facilitates soteriological idealism and suggests that factoring in the material contexts of meditation is useful, both in deciphering the text’s meditation methods and in discussing the metaphysical theory of idealism.

The interface issue in second language acquisition research: An interdisciplinary perspective

The interface issue concerning the nature of interactions between explicit and implicit linguistic knowledge in second language acquisition (SLA) has been a focus of widespread academic interest for almost four decades. However, despite intense debate at the theoretical level and emerging methodologically rigorous studies related to the topic, the issue remains unresolved. With this overview paper, we hope to offer a contribution to the pending theoretical and methodological topics related to the interface in acquiring L2 syntax. First, the paper discusses the definitions and operationalization criteria of implicit and explicit knowledge, as well as their interface. Then, we review the methods and findings of representative studies on domain-general learning and second language acquisition that have explored the interactions between implicit and explicit learning systems. Specifically, we identify the types of interactions that are tenable according to the literature in cognitive psychology and seek evidence for those interactions in the results of published state-of-the-art research. Finally, we compile methodological recommendations for further SLA studies exploring the interface. Following other scholars, throughout the discussion, we argue that bringing the field closer to resolving the interface issue requires an interdisciplinary approach that combines insights and methods from linguistic, psychological and neurocognitive research traditions.

Executive functioning in adults with borderline personality disorder and first-degree biological relatives

Objectives Behavioural dysregulation is a heritable core symptom domain in borderline personality disorder (BPD) that is likely influenced by the integrity of executive functions (EFs). However, the extent to which familial risk for BPD confers decrement to EFs has yet to be comprehensively studied. Methods In this family study, probands with BPD (n = 73), first-degree biological relatives (n = 65), and healthy controls without psychiatric diagnoses (n = 77) were assessed in abstraction, attentional vigilance, working memory, cognitive flexibility, interference resolution, planning, problem solving, and response inhibition. Results In univariate analyses, probands demonstrated lower response inhibition than relatives. Comparatively, discriminant function analyses revealed that lower interference resolution and response inhibition jointly discriminated probands from relatives and controls, whereas a combination of less efficient problem solving and difficulty manipulating mental information discriminated probands and relatives from controls. Moreover, the subset of psychiatrically non-affected relatives demonstrated a pattern of resilience to psychiatric morbidity substantiated by stronger response inhibition and abstraction abilities despite less efficient problem solving. Conclusions Familial risk for BPD is represented predominantly by a pattern of problem-solving and working memory deficits. Resilience to a psychiatric disorder in non-affected relatives reflects both EF weaknesses and strengths, highlighting potential protective factors that should be considered in future neurocognitive research on BPD families.

Psychopathy in women: insights from neuroscience and ways forward for research.

Psychopathy is a severe form of personality disturbance, resulting in a detrimental impact on individuals, healthcare systems, and society as a whole. Until relatively recently, most research in psychopathy has focused on male samples, not least because of its link with criminal behavior and the large proportion of violent crime committed by men. However, psychopathy in women also leads to considerable problems at an individual and societal level, including substance misuse, poor treatment outcomes, and contribution to ever-increasing numbers of female prisoners. Despite this, due to relative neglect, most research into adult female psychopathy is underpowered and outdated. We argue that the field needs revitalizing, with a focus on the developmental nature of the condition and neurocognitive research. Recent work international consortia into conduct disorder in female youth-a precursor of psychopathy in female adults-gives cause for optimism. Here, we outline key strategies for enriching research in this important field with contemporary approaches to other psychiatric conditions.

Does neural face processing explain effects of an attachment-based intervention on maternal sensitivity? A randomized controlled study including pre- and postintervention measures.

BackgroundAlthough there is a large body of literature highlighting the behavioral effects of parenting interventions, studies on the neurocognitive mechanisms involved in such intervention effects remain scarce.PurposeThe aim of the current study was to test whether changes in neural face processing (as reflected in N170 amplitudes) would act as a mediator in the association between the Video‐feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP‐SD) and maternal sensitivity.MethodsA total of 66 mothers of whom a random 33% received the VIPP‐SD and the others a “dummy” intervention participated in pre‐ and postintervention assessments. We recorded mothers' electroencephalographic (EEG) activity in response to photographs of children's neutral, happy, and angry facial expressions. Maternal sensitivity was observed while mothers interacted with their offspring in a semi‐structured play situation.ResultsIn contrast with our expectations, we did not find evidence for mediation of intervention effects on maternal sensitivity by the N170.ConclusionWe discuss that parenting support programs may yield different effects on neurocognitive processes depending on the population and provide recommendations for future research. Our study underscores the importance of reporting null findings and preregistering studies in the field of neurocognitive research.

Beyond olfaction: Beneficial effects of olfactory training extend to aging-related cognitive decline.

Studies on olfactory training (OT) outcomes have mostly been limited to olfactory performance, while direct neural connections between olfactory system and amygdala-hippocampal complex allow expecting OT to have psychological effects. To address this hypothesis, we examined olfactory, cognitive and emotional effects of OT in the group of 68 subjects aged between 50 and 88 years (Mage = 62.8 ± 8.9 years; 28 males) who are likely to experience an age-related decline in olfactory and cognitive performance. We diversified stimuli used in the OT to verify whether odor mixtures result in more effective activation of olfactory receptor neurons than single molecule odors. Subjects were randomly assigned to one of the experimental conditions: (a) simple OT utilizing single-molecule odors; (b) mixtures OT using odor mixtures; (c) control group without OT. Results indicate beneficent effects of the simple OT on cognitive assessment, cognitive decline symptoms, and olfactory sensitivity. OT can be adapted from otorhinolaryngological practice to successfully serve neurocognitive research and in supporting the cognitive-related aging process.

Podmiot ucieleśniony w zaprojektowanym środowisku. Analiza wykorzystania koncepcji afordancji w architekturze

The subject embodied in the designed environment. Analysis of the use of the affordance concept in architecture: James Gibson’s ecological psychology is considered as one of the research subtraditions within embodied cognition. Gibson emphasizes the nature of the agent-environment interaction through the development of the theory of affordances. According to this idea, affordances are relational properties of the environment that enable a specific action for the agent. Currently this concept is being applied in many different contexts. This paper considers the application potential of affordance in architectural studies as a tool that analyses the agent’s interaction with the environment. In this context, the affordance category can be a tool that allows one to take into account the importance of space for the shaping of behavior and interactions between its users, without falling into architectural determinism. The main aim of this study is to analyze affordances as a category that, despite its diversity and vagueness, can play an important role in the embodied view of architecture (which integrates phenomenological trends in architecture and the results of neurocognitive research). The first part of the article is an attempt to synthetically place affordances in the context of embodied cognition and to point out the basic philosophical interpretations and discussions related to Gibson’s concept. In the next part, we situate the concept of affordances in the context of design practice. We also present the pros and cons of applying affordances to this ground. The last section in presenting the concept of affordances is considered within the background of the embodied current in architecture.

Cognitive A Priori and Amodal Perception in the Focus of Experimental Philosophy

The article discusses the prospects of neurophenomenology as a substantiative theory with respect to the results of neurocognitive research. Some relevant ideas and theoretical findings of the phenomenology of Edmund Husserl, which are of great importance for the interpretation of experimental data from neuroscience, are consistently presented and analyzed. In particular, the emphasis is made on the procedure of analogizing apperception (appresentation), based on an even deeper pairing mechanism. In so doing, I consider and trace the evolution of these ideas in Husserl's works of different years and periods. As an example, that clearly demonstrates the universal a priori rock-bottom role of appresentation in cognition and perception, the procedure of amodal completion is chosen. Amodal completion is the process of perception by which an object is apprehended as a whole while some parts of it are occluded by other objects. These research seems to open up wide opportunities for neurophenomenology as the theoretical basis of the sciences of consciousness, mind and brain.

A novel coding scheme for assessing responses in divergent thinking: An embodied approach.

In the present study we devised a novel coding scheme for responses generated in a divergent thinking task. Based on considerations from behavioural and neurocognitive research from an embodied perspective, our scheme aims to capture dimensions of simulations of action or the body. In an exploratory investigation, we applied our novel coding scheme to analyze responses from a previously published dataset of divergent thinking responses. We show that a) these dimensions are reliably coded by naïve raters, and that b) individual differences in creativity influences the way in which different dimensions are used over time. Overall, our results provide new hypotheses about the generation of creative response in the divergent thinking task and should serve to characterize the cognitive strategies used in creative endeavors.

Language attrition: A matter of brain plasticity?

Abstract While it has long been assumed that brain plasticity declines significantly with growing maturity, recent studies in adult subjects show grey and white matter changes due to language learning that suggest high adaptability of brain structures even within short time-scales. It is not known yet whether other language development phenomena, such as attrition, may also be linked to structural changes in the brain. In behavioral and neurocognitive research on language attrition and crosslinguistic influence, findings suggest high plasticity as language interaction patterns of bilingual speakers change constantly and from early stages of language acquisition onwards. In this paper we will speculate on possible links between brain plasticity and L1 attrition in adult bilinguals, with particular attention to a number of factors that are put forward in memory frameworks in order to explain forgetting: time elapsed, frequency of L1 use, and interference from L2. In order to better understand the time-scales involved in the plastic changes during bilingual development, we then discuss some recent studies of re-exposure to L1 in formerly attrited immigrants, and their implications with respect to brain plasticity.

Sensorimotor debilities in digital cultures

This paper reflects on the qualities of living and learning in digital cultures, the design of digital technologies and the philosophical history that has informed that design. It takes as its critical perspective the field of embodied cognition as it has developed over the last three decades, in concert with emerging neurophysiology and neurocognitive research. From this perspective the paper considers cognitive, neurological and physiological effects that are increasingly becoming noticed in user populations, especially young populations. I call this class of conditions ‘sensorimotor debility’, to distinguish it from other psychological, social, cultural and political symptoms associated with computer, internet and social media use.

A Case-Control Study on Behavioral Addictions and Neurocognition: Description of the BANCO and BANCO2 Protocols.

IntroductionOnly two behavioral addictions (BAs) are currently recognized in international classifications (gambling disorder: GbD; gaming disorder: GmD), while some of them await further investigation (food addiction: FA; sexual addiction: SA). Neurocognitive functioning is considered a risk factor for BAs. Research is quite abundant for GbD and highlights specific deficits in several cognitive functions. Nevertheless, grey areas still exist. The aim of this research programme is to investigate the neurocognitive profiles of patients presenting with various BAs and to establish parallels between different forms of BA to achieve a common addiction concept.Methods and AnalysisThis research program is composed of two studies sharing the same methodology but focusing on different samples: the BANCO study aims to include 30 individuals with a GbD, whereas the BANCO2 study aims to include 30 individuals with a GmD, 30 with a SA, and 30 with a FA. Moreover, for each BA group, 30 healthy controls will be recruited, matched by sex, age and education level. Several cognitive tasks will be completed by participants. Cue reactivity and physiological responses, as well as clinical data regarding addiction characteristics and personality, will also be investigated. A composite score based on the cognitive tasks will be computed using principal component analysis (PCA). Overall cognitive performance and detailed performance on the different cognitive tasks will be compared between individuals with BAs and their matched healthy controls using linear models with random effects. Comparisons will also be made between BA groups to investigate specific alterations associated with each disorder.DiscussionThe results of this research programme will impact both research and clinical areas by (i) providing new knowledge for discussions regarding the inclusion of BAs under the spectrum of addictive disorders; (ii) improving understanding of addiction mechanisms in general; (iii) providing clarity in the grey areas in neurocognitive research on BAs and improving the understanding of less studied BAs, (iv) guiding clinicians to propose therapeutic alternatives and complementary programmes.Trial RegistrationBANCO study (ClinicalTrials.gov NCT03202290); BANCO2 study (ClinicalTrials.gov NCT03967418).

INFORMATION, COGNITION, AND OBJECTIVITY

AbstractThe idea that the brain is an information processing system raises some challenging questions about whether information exists independently of brains. Answering these questions is relevant for clarifying the theoretical foundations of the sciences of mind and brain, but also for appropriately interpreting and evaluating the evidence about how brains—and other biological systems—work. This article claims that (1) informational descriptions in the sciences of mind and brain can be genuinely explanatory, despite assuming a mind-dependent notion of information; and (2) that either Popperian objectivity or response-dependence in normal receivers is sufficient for grounding the explanatory role that information often plays in these sciences. Hierarchical predictive processing, which has become a central theoretical framework for neurocognitive research, is used as a case study for supporting these two claims.

Executive functions and insight in OCD: a comparative study

BackgroundAround 25 to 30% of patients with obsessive-compulsive disorder (OCD) do not respond to treatment. These patients have the longest duration of disease and the worst prognosis. Following years of research on this topic, insight has emerged as a potential explanation for this therapeutic resistance. Therefore, it has become important to characterize OCD patients with poor insight. Few studies have focused on the neuropsychological and cognitive characteristics of these patients.MethodsTo help fill this gap, we divided 57 patients into two groups, one with good insight and the other with poor insight, assessed their neuropsychological functions—through a Rey’s figure test, a California verbal learning test, a Toulouse–Piéron test and a Wisconsin Card Sorting Test (WCST)—and compared the results with those of a paired control group.ResultsThe statistical analysis, with a significance level of 95%, revealed differences in the executive function tests, and particularly in the WCST (p ≤ 0.001) and trail-making-test (TMT A/B) (p = 0.002).ConclusionsThese differences suggest that the neuropsychological profile of poor-insight patients is different from their good-insight counterparts, emphasize the role played by the executive functions in insight and highlights the need for more accurate neurocognitive research and treatment.
