A Research Study Contains the Following in Its Introduction Section

question 15

Multiple Choice

A research study contains the following in its Introduction section: "This study was undertaken to explore the effect of massage on total hours of sleep per 24-hour day, in persons averaging fewer than 7 hours of sleep per night, attributable to insomnia. Presumably by increasing endorphin levels, massage seems to provide an immediate relaxation and an ability to sleep immediately following the session, but it is unclear whether these benefits actually extend to total sleep, despite anecdotal support. The claim that massage increases total hours of sleep has been inadequately researched. Does massage increase the total number of hours of daily sleep? It was posited that provision of daily late-morning massage would affect total hours of sleep per 24-hour day. The study's causational explanation was based on the physiological matrix of McCarthy, which includes effects of endorphins on sleep, learning ability, pain, digestive function, and cardiac output. It was taken as established fact that massage is pleasant, that research subjects getting fewer than 7 hours of sleep per night were sleep-deprived, and that endorphins mediated the changes observed."
