Serial diverse imagining task: A new remedy for bedtime complaints of worrying and other sleep-disruptive mental activity

This is a test of super-somnolent mentation theoretical framework using the Serial Diverse Imagining technique. CogSci Apps Corp.\u27s SomnoTest, which is a research version of mySleepButton, was used in the serial diverse imagining group. Submitted to SLEEP 2016 Conference in Dec 2015.

The separateness of social and emotional loneliness in childhood

Much of the childhood loneliness research is misleading because it confounds objective and subjective measures of loneliness. The overall aim of this research was to examine the relationship between social isolation and emotional loneliness. Method: Three extreme groups were identified in a sample of 640 4-9-year-old children. There were two ('rejected' [Nˆ60] and 'lonely' [Nˆ146]) in which social and emotional loneliness were unrelated. The first were socially isolated (rejected) but they did not feel lonely. The second group felt lonely but they were not socially isolated. The third group ('rejected/ lonely') consisted of 61 children who were rejected and also felt lonely. Results: Felt loneliness and social rejection were experienced together by 61 children, but 206 children experienced either one or the other, but not both. The fourth and largest group [Nˆ374] were neither rejected nor lonely. Differences between the groups were found on direct observation measures of solitariness, sociability, and aggression; peer reports of shyness, aggression, prosocial behaviour, disruptive behaviour and inability to take teasing; self-reports of self-worth and competence, self-reports of supportive relationships; and measures of language use

Assessment of chronotype in four- to eleven-year-old children: reliability and validity of the Children's Chronotype Questionnaire (CCTQ)

Individual differences in circadian phase preference ("chronotype") are linked to sleep schedule variability, psychosocial functioning, and specific properties of the circadian clock. While much is known about the development, distribution, and variability of chronotype in adolescents and adults, assessment in prepubertal children has been hindered by a lack of appropriate, reliable, and valid measures. This study presents a detailed description of the assessment of children's chronotype by the Children's ChronoType Questionnaire (CCTQ). The CCTQ is a parent-report, 27-item mixed-format questionnaire resulting in multiple measures of chronotype in 4- to 11-yr-old children: the midsleep point on free days (MSF), a morningness/eveningness scale (M/E) score, and a five-point chronotype (CT) score. The study provides validity data using actigraphy as well as test-retest reliability data for all three chronotype measures and sleep/wake parameters. Overall, the findings indicate moderate to strong agreement between the three measures, adequate associations between chronotype measures and sleep/wake parameters assessed by actigraphy, and excellent temporal stability (reliability)
