Literature on sleep and child development is growing in novel directions across several disciplines necessitating guiding conceptual principles and methodological tools. First, this volume presents a summary of discussions from an SRCD-sponsored multidisciplinary forum on sleep and development, which includes presentation of key issues and guiding recommendations for research priorities in this...

Sleep quality has a large impact on daily performance and general health. Among the different methods of objectively measuring sleep quality, actigraphy continues to be very popular. It can take continuous activity measurements over several days in order to determine sleep-wake cycles and calculate sleep variables, including the three standard sleep variables used in determining sleep quality: ...

The aim of this study was to determine whether wrist actigraphy could be used to assess the daytime effects of stimulant medication in the treatment of narcolepsy. Nine subjects with narcolepsy/cataplexy (medicated and unmedicated) were compared with matched control subjects. Data were collected over 4 days in the subjects' home. It was found that the actigraph variable of Immobility (mean dura...

We propose a novel machine learning-based method for analysing multi-night actigraphy signals to objectively classify and differentiate nocturnal awakenings in individuals with chronic insomnia (CI) their cohabiting healthy partners. analysed from 40 couples one partner seeking treatment insomnia. extracted 12 time-domain dynamic nonlinear features the those CI. These were then used train two l...

Geoghegan et al. (2012) recently reported the sleep quality of 33 college students, aged 20–25 years, using wrist actigraphy in combination with sleep diary and mood questionnaire to know the effect of alcohol on sleep. As a main result, they observed significant decreases in total sleep time and sleep latency associated with alcohol drinking. They speculated on the mechanism in this change of ...
