Conscious awareness refers to the subjective experience of perceiving, thinking, and feeling and the ability to report these experiences. These perceptions and thoughts are experienced as bound to an individual self. A fundamental aspect of this self-consciousness is the sense of bodily self-the experience of one's physical presence distinct from the external world, serving as the spatial...
A Ganzfeld is a homogeneous visual field, devoid of any focal points. Such a stimulus has been used by researchers to study perceptual phenomena in the absence of changes in sensory structure. Others have used it to study altered states of consciousness (ASCs). Until now, these different facets have been studied separately with little attention for the emotional subjective experience. This...

Meditation training is widely used to enhance mental well-being. However, a mechanistic cognitive science framework for understanding how it transforms mental processing is still needed. The act of practicing meditation involves trying to be deliberately conscious of a target content. This requires monitoring the contents of one’s consciousness and regulating them in favor of the target. I...
While consciousness is typically considered equivalent to mental contents, certain meditation practices-including open monitoring (OM)-are said to enable a unique conscious state where meditators can experience mental content from a de-reified perspective as "ongoing phenomena." Phenomenologically, such a state is considered as reduction of intentionality, the mental act upon mental content. We...
During binocular rivalry, conflicting images are presented one to each eye and perception alternates stochastically between them. Despite stable percepts between alternations, modeling suggests that neural signals representing the two images change gradually, and that the duration of stable percepts are determined by the time required for these signals to reach a threshold that triggers an...
While diverse contemplative techniques are employed across a plethora of traditions around the world, contemplative research over the years has not reflected this variety. Despite exponential growth in contemplative research in recent decades, it has largely been dominated within a relatively narrow and inadequately-defined construct of contemplative practice (CP) under the umbrella term...
This is an editorial piece for a special issue (SI) in Frontiers of Psychology on 'The Varieties of Contemplative Experiences and Practices'. While diverse contemplative techniques are employed across a plethora of traditions around the world, contemplative research over the years has not reflected this variety. Despite exponential growth in contemplative research in recent decades, it has...
According to many first-person accounts, consciousness comprises a subject-object structure involving a mental action or attitude starting from the "subjective pole" upon an object of experience. In recent years, many paradigms have been developed to manipulate and empirically investigate the object of consciousness. However, well-controlled investigation of subjective aspects of consciousness...
Contemplative practices are thought to modify one's experience of self and fundamentally change self-referential processing. However, few studies have examined the brain correlates of self-referential processing in long-term meditators. Here, we used the self-referential encoding task (SRET) to examine event-related potentials (ERP) during assessment of pleasant and unpleasant self-views in...
Ambiguous sensory stimuli provide insight into the dynamics of the human mind. When viewing substantially different images in the two eyes (i.e., binocular rivalry), perception spontaneously fluctuates between the two images along with patch-like mixtures of the two, with limited ability to control such fluctuations. Previous studies have shown that long-term meditation training can enable a...
Meditation training is proposed to enhance mental wellbeing by modulating neural activity, particularly alpha and theta brain oscillations, and autonomic activity. Though such enhancement also depends on the quality of meditation, little is known about how these neural and physiological changes relate to meditation quality. One model characterises meditation quality as five increasing levels of...
