The neuropsychological status of pain conditions such as fibromyalgia, commonly categorized as 'psychosomatic' or 'functional' disorders, remains controversial. Activation of brain structures dependent upon subjective alterations of fibromyalgia pain experience could provide an insight into the underlying neuropsychological processes. Suggestion following a hypnotic induction can readily modula...

Subjective experience of a peripherally-induced sensation is found to appear without the substantial delay found for the experience of a cortically-induced sensation. To explain this finding, in relation to the putative delay of up to about 500 ms for achieving the "neuronal adequacy" required to elicit the peripherally-induced experience, a modified hypothesis is proposed: for a peripheral sen...

Conscious perception is typically assessed with either objective or subjective measures (Seth et al., 2008). Measures are considered objective if conscious perception is estimated from performance in a discrimination task; inability to discriminate between stimuli is taken as evidence that participants had no conscious perception (Hannula et al., 2005).Measures are considered subjective if part...

BACKGROUND Although the impact of emergency procedures on the childbirth experience has been studied extensively, a possible association of childbirth experience with indications for emergency interventions has not been reported. OBJECTIVES To compare the impacts on childbirth experience of 'planned' delivery (elective cesarean section and vaginal delivery) versus 'unplanned' delivery (vacuum...

OBJECTIVE The subjective experience of aging, indexed by how old or young an individual feels, has been related to well-being and health-related outcomes among older adults. The present study examined whether subjective age is associated with memory level and changes, as indexed by measures of immediate and delayed recall. A complementary purpose was to test the mediating role of depressive sym...

When developing multimedia as an educational tool formative and summative evaluations should be applied during this process. Among other aspects, these evaluations can pertain to the extent and way of use, the learning contents and their formal presentation, the learning results, the acceptability and the usability of the multimedia tool. Furthermore effectivity and efficiency of the multimedia...

This study examined the overall psychological effects of inebriation facilitated by the naturally-occurring plant hallucinogen Salvia divinorum using a double-blind, randomized, placebo-controlled trial. Thirty healthy individuals self-administered Salvia divinorum via combustion and inhalation in a quiet, comfortable research setting. Experimental sessions, post-session interviews, and 8-week ...

The right and left visual hemifields are represented in different cerebral hemispheres and are bound together by connections through the corpus callosum. Much has been learned on the functions of these connections from split-brain patients [1-4], but little is known about their contribution to conscious visual perception in healthy humans. We used diffusion tensor imaging and functional magneti...

The authors indexed the subjective experience of hypnosis through the use of a continuous behavioral measure of the strength of the participant's experience at the time of the suggestion. Specifically, subjects turned a dial to indicate changes in their experience of the suggested effect during that experience. Thirty-three high, 47 medium, and 28 low hypnotizable subjects were asked to use the...
