The study evaluates the effects of 5 years of religious training on the personalities of 31 residents of a Zen Buddhist monastic seminary. The Minnesota Multiphasic Personality Inventory was administered to each subject each year. Comparison of results at Years 1 and 5 revealed predicted improvements, significant at the .05 level, in scales assessing ego strength and dependency and in two measures of general adjustment. A similar pattern of results was found across a time period of only one year in those subjects who experienced a major religious understanding. Comparison with similar studies conducted in Christian seminaries and religious orders suggests that specific elements of monastic life may influence personal adjustment.

We present a new sparse shape modeling framework on the Laplace-Beltrami (LB) eigenfunctions. Traditionally, the LB-eigenfunctions are used as a basis for intrinsically representing surface shapes by forming a Fourier series expansion. To reduce high frequency noise, only the first few terms are used in the expansion and higher frequency terms are simply thrown away. However, some lower frequency terms may not necessarily contribute significantly in reconstructing the surfaces. Motivated by this idea, we propose to filter out only the significant eigenfunctions by imposing l1-penalty. The new sparse framework can further avoid additional surface-based smoothing often used in the field. The proposed approach is applied in investigating the influence of age (38-79 years) and gender on amygdala and hippocampus shapes in the normal population. In addition, we show how the emotional response is related to the anatomy of the subcortical structures.

<p>Social cognition, including complex social judgments and attitudes, is shaped by individual learning experiences, where affect often plays a critical role. Aversive classical conditioning-a form of associative learning involving a relationship between a neutral event (conditioned stimulus, CS) and an aversive event (unconditioned stimulus, US)-represents a well-controlled paradigm to study how the acquisition of socially relevant knowledge influences behavior and the brain. Unraveling the temporal unfolding of brain mechanisms involved appears critical for an initial understanding about how social cognition operates. Here, 128-channel ERPs were recorded in 50 subjects during the acquisition phase of a differential aversive classical conditioning paradigm. The CS+ (two fearful faces) were paired 50% of the time with an aversive noise (CS upward arrow + /Paired), whereas in the remaining 50% they were not (CS upward arrow + /Unpaired); the CS- (two different fearful faces) were never paired with the noise. Scalp ERP analyses revealed differences between CS upward arrow + /Unpaired and CS- as early as approximately 120 ms post-stimulus. Tomographic source localization analyses revealed early activation modulated by the CS+ in the ventral visual pathway (e.g. fusiform gyrus, approximately 120 ms), right middle frontal gyrus (approximately 176 ms), and precuneus (approximately 240 ms). At approximately 120 ms, the CS- elicited increased activation in the left insula and left middle frontal gyrus. These findings not only confirm a critical role of prefrontal, insular, and precuneus regions in aversive conditioning, but they also suggest that biologically and socially salient information modulates activation at early stages of the information processing flow, and thus furnish initial insight about how affect and social judgments operate.</p>

This paper argues the case for meditation with children. It seeks to define what meditation is, why it is important and how it can be practised with children. Meditation provides a good starting point for learning and creativity. It builds upon a long tradition of meditative practice in religious and humanistic settings and research gives evidence of its practical benefits. We need to help children find natural ways for body and mind to combat the pressures of modern living and to find better ways to help focus their minds on matters of importance. There are strong pedagogical reasons for including meditation as part of the daily experience of pupils of all ages and abilities. Meditation is a proven means for stilling the mind, encouraging mindfulness, and providing optimum conditions for generative thinking and reflection. This paper aims to encourage more experimentation and research into meditative practice with children.

<p>Previous research has reported that individuals high in the need for Power, high in inhibition, and high in power stress (the HHH group) are more likely than other individuals to report more severe illnesses. The present study investigates the possibility that the mechanism underlying this relationship is greater sympathetic activation in the HHH group which has an immunosuppressive effect. College males with the HHH syndrome reported more frequent and more severe illnesses than other individuals, as in previous studies. More of the HHH than other subjects also showed above average epinephrine excretion rates in urine and below average concentrations of immunoglobulin A in saliva (S-IgA). Furthermore, higher rates of epinephrine excretion were significantly associated with lower S-IgA concentrations, and lower S-IgA concentrations were significantly associated with reports of more frequent illnesses. The findings are interpreted as consistent with the hypothesis that a strong need for Power, if it is inhibited and stressed, leads to chronic sympathetic overactivity which has an immunosuppressive effect making individuals characterized by this syndrome more susceptible to illness.</p>

<p>Previous functional imaging studies have shown key roles of the dorsal anterior insula (dAI) and anterior midcingulate cortex (aMCC) in empathy for the suffering of others. The current study mapped structural covariance networks of these regions and assessed the relationship between networks and individual differences in empathic responding in 94 females. Individual differences in empathy were assessed through average state measures in response to a video task showing others' suffering, and through questionnaire-based trait measures of empathic concern. Overall, covariance patterns indicated that dAI and aMCC are principal hubs within prefrontal, temporolimbic, and midline structural covariance networks. Importantly, participants with high empathy state ratings showed increased covariance of dAI, but not aMCC, to prefrontal and limbic brain regions. This relationship was specific for empathy and could not be explained by individual differences in negative affect ratings. Regarding questionnaire-based empathic trait measures, we observed a similar, albeit weaker modulation of dAI covariance, confirming the robustness of our findings. Our analysis, thus, provides novel evidence for a specific contribution of frontolimbic structural covariance networks to individual differences in social emotions beyond negative affect.</p>

BACKGROUND: Hypothalamic-pituitary-adrenal (HPA) system activation is adaptive in response to stress, and HPA dysregulation occurs in stress-related psychopathology. It is important to understand the mechanisms that modulate HPA output, yet few studies have addressed the neural circuitry associated with HPA regulation in primates and humans. Using high-resolution F-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in rhesus monkeys, we assessed the relation between individual differences in brain activity and HPA function across multiple contexts that varied in stressfulness.
METHODS: Using a logical AND conjunctions analysis, we assessed cortisol and brain metabolic activity with FDG-PET in 35 adolescent rhesus monkeys exposed to two threat and two home-cage conditions. To test the robustness of our findings, we used similar methods in an archival data set. In this data set, brain metabolic activity and cortisol were assessed in 17 adolescent male rhesus monkeys that were exposed to three stress-related contexts.
RESULTS: Results from the two studies revealed that subgenual prefrontal cortex (PFC) metabolism (Brodmann's area 25/24) consistently predicted individual differences in plasma cortisol concentrations regardless of the context in which brain activity and cortisol were assessed.
CONCLUSIONS: These findings suggest that activation in subgenual PFC may be related to HPA output across a variety of contexts (including familiar settings and novel or threatening situations). Individuals prone to elevated subgenual PFC activity across multiple contexts may be individuals who consistently show heightened cortisol and may be at risk for stress-related HPA dysregulation.

"The practice of contemplation is one of the great spiritual arts," writes Martin Laird in A Sunlit Absence. "Not a technique but a skill, it harnesses the winds of grace that lead us out into the liberating sea of silence." In this companion volume to his bestselling Into the Silent Land, Laird focuses on a quality often overlooked by books on Christian meditation: a vast and flowing spaciousness that embraces both silence and sound, and transcends all subject/object dualisms. Drawing on the wisdom of great contemplatives from St. Augustine and St. Teresa of Avila to St. Hesychios, Simone Weil, and many others, Laird shows how we can uncover the deeper levels of awareness that rest within us like buried treasure waiting to be found. The key insight of the book is that as our practice matures, so will our experience of life's ordeals, sorrows, and joys expand into generous, receptive maturity. We learn to see whatever difficulties we experience in meditation--boredom, lethargy, arrogance, depression, grief, anxiety--not as obstacles to be overcome but as opportunities to practice surrender to what is. With clarity and grace Laird shows how we can move away from identifying with our turbulent, ever-changing thoughts and emotions to the cultivation of a "sunlit absence"--the luminous awareness in which God's presence can most profoundly be felt. Addressed to both beginners and intermediates on the pathless path of still prayer, A Sunlit Absence offers wise guidance on the specifics of contemplative practice as well as an inspiring vision of the purpose of such practice and the central role it can play in our spiritual lives.

This book takes a bold new look at ways of exploring the nature, origins, and potentials of consciousness within the context of science and religion. It draws careful distinctions between four elements of the scientific tradition: science itself, scientific realism, scientific materialism, and scientism. Arguing that the metaphysical doctrine of scientific materialism has taken on the role of ersatz-religion for its adherents, it traces its development from its Greek and Judeo-Christian origins, focusing on the interrelation between the Protestant Reformation and the Scientific Revolution. It also looks at scientists' long term resistance to the firsthand study of consciousness and details the ways in which subjectivity has been deemed taboo within the scientific community. In conclusion, the book draws on William James's idea for a “science of religion” that would study the nature of religious and, in particular, contemplative experience.
The specific aim of this course is development of a university dance curriculum that will link post-modern dance with Tai Chi as it is understood and practiced by the masters of the discipline in China – both as a practice (i.e., as a set of physical movements known as “Tai Chi Chuan”) and as a spiritual discipline (i.e., “Tai Chi”) worthy of scholarly study. A central hypothesis of this course is that the teaching of Tai Chi Chuan in this country – both in academic and experiential contexts – has generally missed the essence of the actual Chinese discipline by concentrating more on the specific physical steps than on the deeper mental and spiritual principles from which it derives. A major goal of the course is to restore to the curriculum those important principles of employing certain meditation techniques that have not been taught here. The course will apply two central principles of Tai Chi in the context of dance: first, the goal of awareness, or softness, which is simply movement based on stillness; and second, the goal of relational physics, or the intention and orientation of the individual to the whole.

Following E. Goffman's (1967) face threat analysis of social interaction, it was hypothesized that the aggressive, playful content of teasing would vary according to social status and relational satisfaction, personality, role as teaser or target, and gender. These 4 hypotheses were tested in analyses of the teasing among fraternity members (Study 1) and romantic couples (Study 2). Consistent with a face threat analysis of teasing, low-status fraternity members and satisfied romantic partners teased in more prosocial ways, defined by reduced face threat and increased redressive action. Some findings indicate that disagreeable individuals teased in less prosocial ways, consistent with studies of bullying. Targets reported more negative emotion than teasers. Although female and male romantic partners teased each other in similar ways, women found being the target of teasing more aversive, consistent with previous speculation.

We present a new tensor-based morphometric framework that quantifies cortical shape variations using a local area element. The local area element is computed from the Riemannian metric tensors, which are obtained from the smooth functional parametrization of a cortical mesh. For the smooth parametrization, we have developed a novel weighted spherical harmonic (SPHARM) representation, which generalizes the traditional SPHARM as a special case. For a specific choice of weights, the weighted-SPHARM is shown to be the least squares approximation to the solution of an isotropic heat diffusion on a unit sphere. The main aims of this paper are to present the weighted-SPHARM and to show how it can be used in the tensor-based morphometry. As an illustration, the methodology has been applied in the problem of detecting abnormal cortical regions in the group of high functioning autistic subjects.

Brain oscillatory activity is associated with different cognitive processes and plays a critical role in meditation. In this study, we investigated the temporal dynamics of oscillatory changes during Sahaj Samadhi meditation (a concentrative form of meditation that is part of Sudarshan Kriya yoga). EEG was recorded during Sudarshan Kriya yoga meditation for meditators and relaxation for controls. Spectral and coherence analysis was performed for the whole duration as well as specific blocks extracted from the initial, middle, and end portions of Sahaj Samadhi meditation or relaxation. The generation of distinct meditative states of consciousness was marked by distinct changes in spectral powers especially enhanced theta band activity during deep meditation in the frontal areas. Meditators also exhibited increased theta coherence compared to controls. The emergence of the slow frequency waves in the attention-related frontal regions provides strong support to the existing claims of frontal theta in producing meditative states along with trait effects in attentional processing. Interestingly, increased frontal theta activity was accompanied reduced activity (deactivation) in parietal–occipital areas signifying reduction in processing associated with self, space and, time.

<p>Philosophers speak-or, rather, they respond to various forms of speaking that are handed to them. This book by one of our most distinguished philosophers focuses on the communicative aspect of philosophical thought. Peperzak's central focus is addressing: what distinguishes speaking or writing from rumination is their being directed by someone to someone. To be involved in philosophy is to be part of a tradition through which thinkers propose their findings to others, who respond by offering their own appropriations to their interlocutors.After a critical sketch of the conception of modern philosophy, Peperzak presents a succinct analysis of speaking, insisting on the radical distinction between speaking about and speaking to. He enlarges this analysis to history and tries to answer the question whether philosophy also implies a certain form of listening and responding to words of God. Since philosophical speech about persons can neither honor nor reveal their full truth, speaking and thinking about God is even more problematic. Meditation about the archaic Word cannot reach the Speaker unless it turns into prayer, or-as Descartes wrote-into a contemplation that makes the thinker consider, admire, and adore the beauty of God's immense light, as much as the eyesight of my blinded mind can tolerate."Thinking is a work of genuine and original scholarship which responds to the tradition of philosophical thinking with a critique of its language, style, focus, and scope.-Catriona Hanley, Loyola College, Maryland</p>

Two replication studies test in Canada a field theory of the effect of consciousness on social change. The exogenous variable is the number of participants in the largest North American group practice of the Transcendental Meditation and TM-Sidhi program, in Iowa. The first study indicated a significant reduction in violent deaths (homicide, suicide, and motor vehicle fatalities), using both time series intervention analysis and transfer function analysis methods, in weeks following change in the exogenous variable during the period 1983 to 1985. The second study, using time series intervention analysis, gave during and after intervention periods a significant improvement in quality of life on an index composed of the behavioral variables available on a monthly basis for Canada from 1972 to 1986 - homicide, suicide, motor vehicle fatalities, cigarette consumption, and workers' days lost due to strikes. Implications of the findings for theory and social policy are noted briefly.
