We have previously found that attention to internal somatic sensations during a heart beat perception task increases the misperception of external touch on a somatic signal detection task , during which healthy participants erroneously report feeling near-threshold vibrations presented to their fingertip in the absence of a stimulus. However, it has been suggested that mindful interoceptive attention should result in more accurate somatic perception, due to its non-evaluative and controlled nature. To investigate this possibility, 62 participants completed the SSDT before (...) and after a period of brief body-scan mindfulness meditation training, or a control intervention . The meditation intervention reduced tactile misperception and increased sensitivity during the SSDT. This finding suggests that the perceptual effects of interoceptive attention depend on its particular nature, and raises the possibility that body-scan meditation could reduce the misperception of physical symptoms in individuals with medically unexplained symptoms.

The power of the positive moral emotions to uplift and transform people has long been known, but not by psychologists. In 1771, Thomas Jefferson's friend Robert Skipwith wrote to him asking for advice on what books to buy for his library, and for his own education. Jefferson sent back a long list of titles in history, philosophy, and natural science. But in addition to these obviously educational works, Jefferson advised the inclusion of some works of fiction. Jefferson justified this advice (...) by pointing to the beneficial emotional effects of great fiction: [E]very thing is useful which contributes to fix us in the principles and practice of virtue. When any... act of charity or of gratitude, for instance, is presented either to our sight or imagination, we are deeply impressed with its beauty and feel a strong desire in ourselves of doing charitable and grateful acts also. On the contrary when we see or read of any atrocious deed, we are disgusted with its deformity and conceive an abhorrence of vice. Now every emotion of this kind is an exercise of our virtuous dispositions; and dispositions of the mind, like limbs of the body, acquire strength by exercise. (shrink)

Everyone has felt those tingling, tickly sensations occurring spontaneously all over the body in the absence of stimuli. But does anyone know where they come from? Here, right-handed subjects were asked to focus on one hand while looking at it and while looking away and subsequently to map and describe the spatial and qualitative attributes of sensations arising spontaneously. The spatial distribution of spontaneous sensations followed a proximo-distal gradient, similar to the one previously described for the density of receptive units. (...) The intensity and spatial extent of the reported sensations were modulated by the focusing condition, especially in respect of the left hand. Convergent focusing acted upon the conscious perception of sensations by enhancing or suppressing them. To our knowledge, this is the first ever study of spontaneous sensations, and it offers considerable insight into their sources. The presence of the proximo-distal distributional gradient is a clear sign that receptive units are involved. The enhancement/suppression effects also confirm the involvement of attention. Finally, left-hand dominance suggests several right-hemisphere processes may be involved, such as spatial and tactile perception, and probably interoception. (shrink)

Aesthetic chills occur in artistic, scientific and religious context. We introduce a theoretical framework relating them to humans’ vital need for cognition. We discuss the implications of such a framework and the plausibility of our hypothesis. Numerous references to chills are introduced.
