Action plan interrupted: resolution of proactive interference while coordinating execution of multiple action plans during sleep deprivation.

Abstract: The ability to retain an action plan to execute another is necessary for most complex, goal-directed behavior Research shows that executing an action plan to an interrupting event can be delayed when it partly overlaps (vs does not overlap) with the retained action plan This phenomenon is known as partial repetition costs (PRCs) PRCs reflect proactive interference, which may be resolved by inhibitory, executive control processes We investigated whether these inhibitory processes are compromised due to one night of sleep deprivation Participants were randomized to a sleep-deprived group or a well-rested control group All participants performed an action planning task at baseline after a full night of sleep, and again either after a night of sleep deprivation (sleep-deprived group) or a full night of sleep (control group) In this task, two visual events occurred in a sequence Participants retained an action plan to the first event in working memory while executing a speeded action to the second (interrupting) event; afterwards, they executed the action to the first event The two action plans either partly overlapped (required the same hand) or did not (required different hands) Results showed slower responses to the interrupting event during sleep deprivation compared to baseline and the control group However, the magnitude of the PRCs was no different during sleep deprivation compared to baseline and the control group Thus, one night of sleep deprivation slowed global responses to the interruption, but inhibitory processes involved in reducing proactive interference while responding to an interrupting event were not compromised These findings are consistent with other studies that show sleep deprivation degrades global task performance, but does not necessarily degrade performance on isolated, executive control components of cognition The possibility that our findings involve local as opposed to central inhibition is also discussed

Sleep quality estimation device, sleep quality estimation method and program for sleep quality estimation

Abstract: In a sleep quality estimation device, a respiration sensor detects the respiratory waveform of a subject. A sleep stage estimation unit estimates the sleep stage of the subject during sleep based on the respiratory waveform detected by the respiration sensor. In a sleep rhythm model database, models associated with the appearance probability of δ-wave for the sleep stage during sleep are recorded. A sleep quality estimation unit estimates the appearance time of δ-wave of the subject during sleep based on the sleep stage of the subject estimated by the sleep stage estimation unit and the models associated with the appearance probability of δ-wave for the sleep stage recorded in the sleep rhythm model database, and estimates the sleep quality of the subject based on the appearance time of δ-wave.

A Personalized Sleep Quality Assessment Mechanism Based on Sleep Pattern Analysis

Abstract: Most sleep management systems lack reliable assessment of sleep quality and receive single information source only. In this paper, we proposed a sleep quality assessment mechanism based on the physiological sleep pattern with scenarios of multiple data sources. This mechanism provides an intuitive personalized sleep quotient which encourages users to have long-term usage of sleep management service. It further helps users to understand their sleep patterns and adjust sleep habits. In addition, sleep medical professionals can strengthen the diagnostic judgment with this assessment mechanism.

Humanized sleep monitoring alarm clock and control method thereof

Abstract: The invention discloses a humanized sleep monitoring alarm clock and a control method thereof. The humanized sleep monitoring alarm clock comprises piezoelectric sensors, an acquisition circuit, an analog-digital converter, a processor, an awakening device and a timer. Sleeping stages are judged according to eye movement frequency and combined with preset awakening time to enable the awakening device to be controlled to start at a light sleep stage. A user is awakened at the light sleep stage by the humanized sleep monitoring alarm clock according to the sleeping stages of the user and the awakening time preset by the user, so that the user can get into a waking state more quickly on the premise that life arrangement of the user is not delayed, and sleep efficiency can be improved within limited sleep time. The humanized sleep monitoring alarm clock is simple and can be integrated on a blinder to be worn by the user during sleeping, and normal sleeping of the user is unaffected. The piezoelectric sensors of the blinder integrated 'humanized' clock are arranged in the blinder and closely attachable to a human body, and continuity and accuracy in timing of the clock are guaranteed.
