Thirty-two participants were tested for both resting electroencephalography (EEG) and neuropsychological function. Eight one-minute trials of resting EEG were recorded from 14 channels referenced to linked ears, which was rederived to an average reference. Neuropsychological tasks included Verbal Fluency, the Tower of London, and Corsi's Recurring Blocks. Asymmetries in EEG alpha activity were correlated with performance on these tasks. Similar patterns were obtained for delta and theta bands. Factor analyses of resting EEG asymmetries over particular regions suggested that asymmetries over anterior scalp regions may be partly independent from those over posterior scalp regions. These results support the notions that resting EEG asymmetries are specified by multiple mechanisms along the rostral/caudal plane, and that these asymmetries predict task performance in a manner consistent with lesion and neuroimaging studies.

<p>Drawing its main source of inspiration from a naturalized interpretation of Husserlian phenomenology, On Becoming Aware: A Pragmatics of Experiencing attempts to examine closely the nature of experience and how we may become aware of our own mental life. The authors also focus on how this project fits into the larger context of cognitive science, psychology, neurosciences, and philosophy. Additional partners in the effort to better understand experience are the contemplative systems of the world's spiritual or wisdom traditions, including particularly that of Buddhism. The book includes three separate glossaries of technical terms in phenomenology, the cognitive sciences, and Tibetan Buddhism. The book On Becoming Aware seeks a disciplined and practical approach to exploring human experience. While much of the book draws its inspiration from the phenomenological theories of Husserl, other approaches to the direct study of experience are also explored in depth. One of these approaches is embodied by the world's spiritual or wisdom or contemplative traditions such as Sufism, Buddhism, the Philokalia tradition, and others. Collectively, these traditions have come upon a variety of their own insights and methods for understanding experience, or, to use words from the phenomenological tradition, has developed its own ways of phenomenological reduction Amongst the various wisdom traditions, the authors focus mainly on Buddhism. The authors give an introduction to Buddhist theory and history, followed by an in-depth discussion of the Buddhist contemplative practices of mindfulness, śamatha, vipaśyanā, tonglen (gtong len), lojong (blo sbyong), dzokchen (rdzogs chen), and mahāmudrā. The authors then relate this discussion to themes from philosophy and phenomenology explored earlier in the book, paricularly Husserl's concept of épochè. (Zach Rowinski 2005-01-17) Publisher's description: This book searches for the sources and means for a disciplined practical approach to exploring human experience. The spirit of this book is pragmatic and relies on a Husserlian phenomenology primarily understood as a method of exploring our experience. The authors do not aim at a neo-Kantian a priori ‘new theory’ of experience but instead they describe a concrete activity: how we examine what we live through, how we become aware of our own mental life. The range of experiences of which we can become aware is vast: all the normal dimensions of human life (perception, motion, memory, imagination, speech, everyday social interactions), cognitive events that can be precisely defined as tasks in laboratory experiments (e.g., a protocol for visual attention), but also manifestations of mental life more fraught with meaning (dreaming, intense emotions, social tensions, altered states of consciousness). The central assertion in this work is that this immanent ability is habitually ignored or at best practiced unsystematically, that is to say, blindly. Exploring human experience amounts to developing and cultivating this basic ability through specific training. Only a hands-on, non-dogmatic approach can lead to progress, and that is what animates this book.</p>

Terror management theory posits that people tend to respond defensively to reminders of death, including worldview defense, self-esteem striving, and suppression of death thoughts. Seven experiments examined whether trait mindfulness--a disposition characterized by receptive attention to present experience--reduced defensive responses to mortality salience (MS). Under MS, less mindful individuals showed higher worldview defense (Studies 1-3) and self-esteem striving (Study 5), yet more mindful individuals did not defend a constellation of values theoretically associated with mindfulness (Study 4). To explain these findings through proximal defense processes, Study 6 showed that more mindful individuals wrote about their death for a longer period of time, which partially mediated the inverse association between trait mindfulness and worldview defense. Study 7 demonstrated that trait mindfulness predicted less suppression of death thoughts immediately following MS. The discussion highlights the relevance of mindfulness to theories that emphasize the nature of conscious processing in understanding responses to threat.

BACKGROUND: Studies using electroencephalogram (EEG) measures of activation asymmetry have reported differences in anterior asymmetry between depressed and nondepressed subjects. Several studies have suggested reciprocal relations between measures of anterior and posterior activation asymmetries. We hypothesized that depressed subjects would fail to show the normal activation of posterior right hemisphere regions in response to an appropriate cognitive challenge.
METHODS: EEG activity was recorded from 11 depressed and 19 nondepressed subjects during the performance of psychometrically matched verbal (word finding) and spatial (dot localization) tasks. Band power was extracted from all epochs of artifact-free data and averaged within each condition. Task performance was also assessed.
RESULTS: Depressed subjects showed a specific deficit in the performance of the spatial task, whereas no group differences were evident on verbal performance. In posterior scalp regions, nondepressed controls had a pattern of relative left-sided activation during the verbal task and relative right-sided activation during the spatial task. In contrast, depressed subjects failed to show activation in posterior right hemisphere regions during spatial task performance.
CONCLUSIONS: These findings suggest that deficits in right posterior functioning underlie the observed impairments in spatial functioning among depressed subjects.

BACKGROUND: The frontal lobe has been crucially involved in the neurobiology of major depression, but inconsistencies among studies exist, in part due to a failure of considering modulatory variables such as symptom severity, comorbidity with anxiety, and distinct subtypes, as codeterminants for patterns of brain activation in depression.
METHODS: Resting electroencephalogram was recorded in 38 unmedicated subjects with major depressive disorder and 18 normal comparison subjects, and analyzed with a tomographic source localization method that computes the cortical three-dimensional distribution of current density for standard electroencephalogram frequency bands. Symptom severity and anxiety were measured via self-report and melancholic features via clinical interview.
RESULTS: Depressed subjects showed more excitatory (beta3, 21.5-30.0 Hz) activity in the right superior and inferior frontal lobe (Brodmann's area 9/10/11) than comparison subjects. In melancholic subjects, this effect was particularly pronounced for severe depression, and right frontal activity correlated positively with anxiety. Depressed subjects showed posterior cingulate and precuneus hypoactivity.
CONCLUSIONS: While confirming prior results implicating right frontal and posterior cingulate regions, this study highlights the importance of depression severity, anxiety, and melancholic features in patterns of brain activity accompanying depression.

Fragile X syndrome (FXS) is the most commonly known genetic disorder associated with autism spectrum disorder (ASD). Overlapping features in these populations include gaze aversion, communication deficits, and social withdrawal. Although the association between FXS and ASD has been well documented at the behavioral level, the underlying neural mechanisms associated with the social/emotional deficits in these groups remain unclear. We collected functional brain images and eye-gaze fixations from 9 individuals with FXS and 14 individuals with idiopathic ASD, as well as 15 typically developing (TD) individuals, while they performed a facial-emotion discrimination task. The FXS group showed a similar yet less aberrant pattern of gaze fixations compared with the ASD group. The FXS group also showed fusiform gyrus (FG) hypoactivation compared with the TD control group. Activation in FG was strongly and positively associated with average eye fixation and negatively associated with ASD characteristics in the FXS group. The FXS group displayed significantly greater activation than both the TD control and ASD groups in the left hippocampus (HIPP), left superior temporal gyrus (STG), right insula (INS), and left postcentral gyrus (PCG). These group differences in brain activation are important as they suggest unique underlying face-processing neural circuitry in FXS versus idiopathic ASD, largely supporting the hypothesis that ASD characteristics in FXS and idiopathic ASD reflect partially divergent impairments at the neural level, at least in FXS individuals without a co-morbid diagnosis of ASD.

Buddhist meditation practice is perceived as non-relational. Yet a serious meditator develops an intimacy with herself that is an asset to being in a healthy relationship. In this essay, using composite profiles of patients, I pursue my interest in relationships and family life as a path to mental health and a home to enlightened experience. The intimacy of a relationship with oneself, with another and within family provides a container that may enable us to let go of our fixed sense of self.

Buddhism has made its way into American popular culture, particularly within the arena of death and dying. The growing influence of Buddhism on the American way of dying has been fostered through its connection with the American hospice movement. This paper describes the developing contact between Buddhism and hospice and documents the efforts of several prominent Buddhist organizations to revolutionize American death practices. The Buddhist approach to death has captured the interest of an American public attracted to its nonsectarian language of spirituality and pragmatic techniques for dealing with death.

The distinct definition of stress postulated by Buddhist and Western cultures is the foundation for their different coping styles, traditions, and practices. Dukkha, derived from Buddha's Four Noble Truths, appears on the surface similar to psychological stress. Further examination of the Eastern cosmology yields a fundamental disagreement between Western psychological theory and Buddhists' conception of suffering and stress related to incorporating reality into the formulation. Cross-cultural research on traditional approaches to coping with occupational stress found that problem solving was the most effective strategy, however in Thailand meditation helped nurses cope with a variety of stressors such as dealing with death and dying.

The category "experience" has played a cardinal role in modern studies of Buddhism. Few scholars seem to question the notion that Buddhist monastic practice, particularly meditation, is intended first and foremost to inculcate specific religious or "mystical" experiences in the minds of practitioners. Accordingly, a wide variety of Buddhist technical terms pertaining to the "stages on the path" are subject to a phenomenological hermeneutic-they are interpreted as if they designated discrete "states of consciousness" experienced by historical individuals in the course of their meditative practice. This paper argues that the role of experience in the history of Buddhism has been greatly exaggerated in contemporary scholarship. Both historical and ethnographic evidence suggests that the privileging of experience may well be traced to certain twentieth-century Asian reform movements, notably those that urge a "return" to zazen or vipassanā meditation, and these reforms were profoundly influenced by religious developments in the West. Even in the case of those contemporary Buddhist schools that do unambiguously exalt meditative experience, ethnographic data belies the notion that the rhetoric of meditative states functions ostensively. While some adepts may indeed experience "altered states" in the course of their training, critical analysis shows that such states do not constitute the reference points for the elaborate Buddhist discourse pertaining to the "path." Rather, such discourse turns out to function ideologically and performatively-wielded more often than not in the interests of legitimation and institutional authority.
