While the exhibition contextualized mindfulness within the Buddhist tradition, Ayesha's research on the history of therapeutic relaxation provided an opportunity to demonstrate the social and structural links between secular mindfulness and twentieth-century relaxation practices. Keywords Muscle relaxation • Mind-body medicine • Rest • Stress • Twentieth-century history of medicine Today's Western 'mindfulness movement' is often portrayed as a sign of and remedy for our restless, overloaded times. Contemporary mindfulness-based interventions comprise treatments for pain, mental illness and stress management and have become an integral part of preventive medicine, lifestyle and well-being agendas. In Britain, the 2015 Mindfulness All-Party Parliamentary Group report 'Mindful NationUK', 1 recommended that mindfulness be taught within schools, prisons, the workplace, and doctor and teacher training courses; there is now a burgeoning ChAPTeR 9

It is unknown, however, whether a later stage, feature extraction, is also slowed. To answer this question, an additive factors method (AFM) experiment was conducted which employed seven well trained subjects whose arterial oxyhaemoglobin saturation was controlled at 63% with low oxygen mixtures. The subjects responded to oddball names presented on a computer screen and both reaction time (RT) and the event-related brain potential P300 were measured. The luminance and quality of the names was varied factorially to influence the preprocessing and feature extraction stages, respectively. RT and P300 latency showed the same pattern of results: stimulus luminance and signal quality were additive, indicating that AFM assumptions were met; hypoxia and stimulus luminance were interactive but hypoxia and signal quality were additive. In conjunction with other evidence...

To determine if the stimulus identification stage of information processing is slowed by hypoxia,... more To determine if the stimulus identification stage of information processing is slowed by hypoxia, eight highly trained subjects performed a mental rotation task involving same or different responses to pairs of two-dimensional figures rotated in the picture plane. They breathed low oxygen mixtures adjusted to maintain arterial blood oxygen saturation at 64%. The results showed that hypoxia increased the intercept rather than the slope of the linear function relating reaction time to angle of rotation. According to Additive Factors Method logic, this result indicates that hypoxia does not slow stimulus identification. This is further evidence against the long-held view that hypoxia impairs information processing mechanisms throughout the system--the multiple loci hypothesis. The authors propose instead the early slowing hypothesis. According to this view, the slowing produced by hypoxia is highly specific to one or two early stages of visual processing, and this early slowing acts as a bottleneck to later processing.
