Specific and nonspecific thalamocortical functional connectivity in normal and vegetative states

Recent theoretical advances describing consciousness from information and integration have highlighted the unique role of the thalamocortical system in leading to integrated information and thus, consciousness. Here, we examined the differential distributions of specific and nonspecific thalamocortical functional connections using resting-state fMRI in a group of healthy subjects and vegetative-state patients. We found that both thalamic systems were widely distributed, but they exhibited different patterns. Nonspecific connections were preferentially associated with brain regions involved in higher-order cognitive processing, self-awareness and introspective mentalizing (e.g., the dorsal prefrontal and anterior cingulate cortices). In contrast, specific connections were prevalent in the ventral and posterior part of the prefrontal and precuneus, known involved in representing externally-directed attentions. Significant reductions of functional connectivity in both systems, especially the nonspecific system, were observed in VS. These data suggest that brain networks sustaining information and integration may be differentiated by the nature of their thalamic functional connectivity.     

A Turing Test for Computational and Associative Theories of Learning

A Turing test is proposed to evaluate current computational and associative models of learning, and to guide theoretical developments. This test requires a specification of the procedures to which the model applies, a sampling of procedures and response measures, and an objective way to determine the difficulty of discriminating the responses of the model from the responses of the animal. Scalar timing theory is used as an example of a well-developed computational theory of timing that involves addition, multiplication, division, and sampling. The behavioral theory of timing is used as an example of a well-developed associative theory of timing that involves state transitions and strengthening of connections. A Turing test provides a way to evaluate such theories.     

Modeling self on others: An import theory of subjectivity and selfhood

This paper outlines an Import Theory of subjectivity and selfhood. Import theory claims that subjectivity is initially perceived as a key feature of other minds before it then becomes imported from other minds to own minds whereby it lays the ground for mental selfhood. Import theory builds on perception-production matching, which in turn draws on both representational mechanisms and social practices. Representational mechanisms rely on common coding of perception and production. Social practices rely on action mirroring in dyadic interactions. The interplay between mechanisms and practices gives rise to model self on others. Individuals become intentional agents in virtue of perceiving others mirroring themselves. The outline of the theory is preceded by an introductory section that locates import theory in the broader context of competing approaches, and it is followed by a concluding section that assesses import theory in terms of empirical evidence and explanatory power.     

The burdens-benefits ratio consideration for medical administration of nutrition and hydration to persons in the persistent vegetative state.

In this article, Harvey notes the initial confusion about the statement made by the pope concerning artificial nutrition and hydration on patients suffering persistent vegetative states (PVS) due to misunderstanding through the translation of the pope's words. He clarifies and assesses what was meant by the statement. He also discusses the problems of terminology concerned with the subject of PVS. Harvey concludes that the papal allocution was in line with traditional Catholic bioethics, and that while maintaining the life of a patient is favorable, in particular cases this presumption wanes when it is clear that this treatment modality would be futile or very burdensome.     

Consciousness lost and found: subjective experiences in an unresponsive state

Anesthetic-induced changes in the neural activity of the brain have been recently utilized as a research model to investigate the neural mechanisms of phenomenal consciousness. However, the anesthesiologic definition of consciousness as “responsiveness to the environment” seems to sidestep the possibility that an unresponsive individual may have subjective experiences. The aim of the present study was to analyze subjective reports in sessions where sedation and the loss of responsiveness were induced by dexmedetomidine, propofol, sevoflurane or xenon in a nonsurgical experimental setting. After regaining responsiveness, participants recalled subjective experiences in almost 60% of sessions. During dexmedetomidine sessions, subjective experiences were associated with shallower “depth of sedation” as measured by an electroencephalography-derived anesthesia depth monitor. Results confirm that subjective experiences may occur during clinically defined unresponsiveness, and that studies aiming to investigate phenomenal consciousness under sedative and anesthetic effects should control the subjective state of unresponsive participants with post-recovery interviews.     

The living state,evolution and consciousness

The purpose of the paper is to discuss the phenomenon of life through the aspect of consciousness and in particular to analyze the role which consciousness plays in the living state (the L‐state for short) as well as the consequences of the development of consciousness for the evolution of living beings. Consciousness is an epiphenomenon of knowledge. The discussion of the role of consciousness in life will have to involve an elucidation of the role of knowledge. This will be done in light of and using the ideas of the theory of the Ecology of Knowledge developed by the author (Wojciechowski, 1975, 1986, 1989).

Because of the special nature of consciousness, the paper will deal with the methodological problems of the study of consciousness, and, therefore of the study of the living state.     

State and Society in the Political Thought of the Moscow Slavophiles

Leading members of the Slavophile circle shared a commonWeltanschauung, fostered by a complex reaction to thesocial and political changes taking place in mid-nineteenth-centuryRussia. There was, however, considerable diversity in their views aboutthe character and value of the Russian state apparatus. While theyall criticised the bureaucratic ethos of the tsarist state,a number of them recognised that it played a critical role in stabilising deep-seated social tensions in Russian society. Inthe late 1850s, some members of the Slavophile circle also cameto recognise that the state apparatus could play a positiverole in eliminating serfdom. Nevertheless, in the wake ofthe Emancipation Edict of 1861, conflict over the roleof the Russian state became the most divisive issuefor surviving members of the Slavophile circle.     

Benti, practice and state: On the doctrine of mind in the four chapters of Guanzi

“Xin 心 (Mind)” is one of the key concepts in the four chapters of Guanzi. Together with Dao, qi 气 (air, or gas) and de 德 (virtue), the four concepts constitute a complete system of the learning of mind which is composed of the theory of benti 本体 (root and body), the theory of practice and the theory of spiritual state. Guanzi differentiates the two basic layers of mind—the essence and the function. It tries to attain a state of accumulated jing 精 (essence, anima) and nourished qi, in which qi is concentrated in a miraculous way, through a series of methods of mind cultivation and nurturing, including being upright, calm, tranquil and moderate, and to concentrate the mind and intention. The doctrine of mind of the four chapters of Guanzi influenced Daoism and Confucianism and is a key link in the history of Chinese thought. It is a prelude to the merger of Confucianism, Daoism and Buddhism.     

More dead than dead: perceptions of persons in the persistent vegetative state

Patients in persistent vegetative state (PVS) may be biologically alive, but these experiments indicate that people see PVS as a state curiously more dead than dead. Experiment 1 found that PVS patients were perceived to have less mental capacity than the dead. Experiment 2 explained this effect as an outgrowth of afterlife beliefs, and the tendency to focus on the bodies of PVS patients at the expense of their minds. Experiment 3 found that PVS is also perceived as “worse” than death: people deem early death better than being in PVS. These studies suggest that people perceive the minds of PVS patients as less valuable than those of the dead – ironically, this effect is especially robust for those high in religiosity.     

The excitatory state in the triangular constant method

The Triangular Constant Method was designed for the measurement of discriminability between sensory stimuli. Its original model assumes a steady excitatory detection state. The purpose of this paper is to elaborate on the consequences of assuming a variable excitatory state and to formulate the concomitant model.     

Missing piece of the puzzle in the science of consciousness: Resting state and endogenous correlates of consciousness

Consciousness still stands as one of the most interesting and the most elusive problems of neuroscience. Finding its correlates is the first step toward its satisfactory explanation. Several theories have proposed its correlates but none of them seem to be generally accepted even though most of them share some very similar elements. These elements are the activity of the thalamus, which is considered by some as the central region for consciousness, and gamma synchronization, which should be the general principal for the emergence of conscious experience. However, all of these proposed theories share one characteristic and that is that they do not take into consideration the recently discovered endogenous activity of the brain, which is generally associated with the default mode network. Although the activity of this large scale brain network is in correlation with various levels of consciousness it is still missing in discussions of consciousness. This review recognizes the importance of endogenous activity and points out the important discoveries of endogenous activity that could be an important step toward a satisfactory explanation of consciousness.     

The translation and validation of the Mini‐K scale in Japanese

The purpose of this study was to validate the 20‐item Mini‐K scale, which is the short form of the Arizona Life History Battery, as translated into Japanese. Two samples of Japanese adults (N = 2000; 50.0% men; Mage = 40.9 for the first survey; N = 400; 50.0% men; Mage = 42.2 for the second survey) completed a web‐based questionnaire, including the Japanese translation of the Mini‐K. The results showed that the psychometric properties of the Japanese Mini‐K scale were comparable to those of the original English version. The scale had good reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the Mini‐K scores and life history indicators. In addition, the Mini‐K score was related to both personality and psychosomatic health. The translated scale provides a valid and reliable instrument in Japanese that measures human life‐history strategy.     

Mental Attention, Consciousness, and the Progressive Emergence of Wisdom

I discuss the mental–attentional mechanisms of consciousness, meditation, and the emergence of wisdom. A developmental (neoPiagetian), dynamic flash-light model of mental attention is used. I model the initial stages of consciousness in infancy, showing that the growth of consciousness is influenced by the number of schemes that attention can coordinate. I discuss ordinary consciousness in adults and the stages/levels of adult development in consciousness. Wisdom is defined as an expectable but often missed outcome of adult development. To accelerate access to wisdom, two complementary paths are mentioned: a natural life-experience path and a meditation path. Maturational organismic factors and the role of mental attentional mechanisms in these two paths are discussed, and a constructivist neuropsychological model of what happens in the brain during meditation, and in higher consciousness, is sketched. Processes involved in higher stages of consciousness are then examined from this perspective.     

Behavioral coaching in the development of skills in football, gymnastics, and tennis

A review of the literature indicates that methods of skill acquisition based on the operant paradigm have been scientifically validated with many motor behaviors. However, these procedures have been limited to the use of positive reinforcement for correct performance when applied to the acquisition of complex sports skills in natural settings. To find complementary procedures to enhance skill acquisition, a coaching method involving several behavioral techniques was developed that focused on remediation of errors. This coaching method combined the following components: (1) systematic use of verbal instructions and feedback, (2) positive and negative reinforcement, (3) positive practice, and (4) time out. Three sports, football, gymnastics, and tennis, were selected to determine the effectiveness and generality of this behavioral coaching method. A total of 23 male and female subjects, ranging in age from 11 to 35, was included in this study. Baseline data were first collected for each sport under standard coaching conditions. Next, the behavioral coaching method was evaluated depending on the sport in either a multiple baseline or a reversal design. The behavioral dimensions selected were blocking in football; backward walkovers, front hand springs, and reverse kips in gymnastics; and the forehand, backhand, and serve in tennis. Behavioral coaching was immediately effective in increasing the correct execution of complex skills in all three sports. Gains of up to 10 times the baseline performance were achieved in each sport. In football, behavioral coaching resulted in an increase in correct blocking performance from a baseline average of 5% to 51.3%. Gymnasts' performances increased from baseline averages of 2.7% to 52.6% across the three skills. In tennis, standard coaching produced an average of 6% correct performance which increased dramatically under behavioral coaching to 57% across the three strokes. The success of the behavioral coaching package used here suggests that a technology of behavior may offer additional and complementary strategies to the acquisition of motor skills in the natural environment.     

Beyond totem and idol,the sexuate other

The author interprets idolatry, totemism, sacrilege and taboo through her theory of sexual difference and her study of Eastern spirituality. She argues that the taboo on spirituality in Western culture has cancelled difference, resulting in our current forms of idolatry. Preserving difference, however, would allow the transcendence of the human other to exist. The task of learning to respect difference is central to human spirituality and spiritual progression. The article is a translation of “La transcendance de l’autre” in Autour d’idôlatrie: figures actuelles de pouvoir et de domination, Ed. Bernard Van Meenen, Publications des Facultés Universitaires Saint-Louis, Brussels: 2003.     

Speculations on the emergence of self-awareness in big-brained organisms: the roles of associative memory and learning, existential and religious questions, and the emergence of tautologies

This paper argues that self-awareness emerges in organisms whose brains have a sufficiently integrated, complex ability for associative learning and memory. Continual sensory input of information related to the organism leads to the formation of a set of associations that may be termed an organismal “self-image”. After providing the basic mechanistic basis for the emergence of an organismal self-image, this paper proceeds to go through a representative list of behaviors associated with self-awareness, and shows how associative memory and learning, combined with an organismal self-image, leads to the emergence of these various behaviors. This paper also discusses various tautologies that invariably emerge when discussing self-awareness. We continue with various speculations on manipulating self-awareness, and discuss how concepts from set and logic theory may provide a useful set of tools for understanding the emergence of higher cognitive functions in complex organisms.     

Religion and state entanglement and interstate armed conflict initiation, 1990–2010

ABSTRACT

The relationship of religion to armed conflict initiation, as opposed to occurrence, remains understudied and undertheorised. The same is true for the relationship of religion to armed conflicts between states, cf. intra-state or extra-state conflict. This contribution adds to the understanding of both of these conflict outcomes. It examines the relationship to interstate armed conflict initiation of state religion, operationalised as government involvement in religion in the Religion and State dataset of Jonathan Fox. We find sufficient evidence to conclude that religion–state entanglement does raise states’ propensities towards first use of military force. Official religion and official support are both strongly correlated with that outcome. Legislative support to the majority religion is also well correlated with it. State-level discrimination against minority religions is weakly but positively correlated, but heavy regulation of majority religions is not correlated. We further find evidence that minority discrimination, majority regulation and legislative support wield their effects in tandem more strongly than they do individually. The foregoing supports the theory that official religious preference does make states more militant.     

A Norwegian translation of the self–liking and competence scale

Although global self-esteem has historically been assumed to be a unidimensional construct, recent theory and research has challenged this assumption. Instead, it has been suggested that self-esteem might more fruitfully be viewed as a two-dimensional construct composed of: (a) self-liking, based on our perceptions of feedback from our social environment; and (b) self-competence, based on our internal conceptions of success and failure in performing tasks. The Self-Liking and Competence Scale (SLCS) is a self-esteem measure that has recently been developed based on this two-dimensional conceptualization of self-esteem. The purpose of the present research was to validate a Norwegian translation of the SLCS. 372 participants were given a translated version of the SLCS, and the translated scale exhibited psychometric properties similar to those of the original English version of the scale.     

Religion–state relations and public opinion: norms,institutions and social consensus

ABSTRACT

Are levels of religion–state regulation associated with cross-national variation in attitudes related to the place of religion in public life? Data sources measuring both the institutional relationship between religion and state and public opinion on the political role of religion have significantly improved in recent years, but scholars have just begun to examine relationships between political institutions and public attitudes. This contribution tests several potential examples of such links by exploring the relationship between religion–state institutions and norms of religion and politics, both between and within countries. The contribution first develops theoretical expectations regarding the institutional correlates of public opinion, then conducts initial tests of these expectations by blending data from the Religion and State project with comparative survey data drawn from Waves 4 and 5 of the World Values Survey. Analysis demonstrates modest links between institutions and aggregate public views, a relationship between institutions and social consensus, and, most robustly, consistent variation in institutional effects across political regime type.
