Lulling them to sleep

One of my fondest memories as a child is falling asleep to the sound of my grandmothe singing me a lullaby. Now that I am a teacher in a specialized preschool with small classes try to provide some fond memories for my children by singing them to sleep at naptime.Martha Christine is a Kindergarten Teacher at the Wiley House Preschool in Allentown, PA.     

Improving sleep,cognitive functioning and academic performance with sleep education at school in children

We aimed at measuring the impact of a school-based sleep education program (ENSOM: ‘EN’ for ‘ENfant’ and SOM for ‘SOMmeil’ in French) on sleep, cognitive functioning and academic performance in children. In contrast with existing sleep education programs, ENSOM was designed by sleep experts with the intent of being autonomously achieved by teachers. One-hundred and thirty children aged 8–9 years took part in control versus ENSOM interventions. Compared to the control intervention, total sleep time was extended by 31 min per night, sleep efficiency improved by 2.9%, and sleep latency and wake after sleep onset were shortened by 7.7 and 4.5 min respectively after the ENSOM program. Sleep improvement remained significant at one-year follow-up. Attention, executive functioning, academic performance and parents' sleep knowledge also improved significantly. Given the frequency of sleep curtailment in children, school-based programs could be an efficient method to implement sleep education on a large scale.

Marital conflict and disruption of children's sleep

Marital conflict was examined as a predictor of the quality and quantity of sleep in a sample of healthy 8- to 9-year-olds. Parents and children reported on marital conflict, the quantity and quality of children's sleep were examined through an actigraph worn for 7 consecutive nights, and child sleepiness was derived from child and mother reports. Increased marital conflict was associated with disruptions in the quantity and quality of children's sleep as well as subjective sleepiness, even after controlling for child age, ethnic group membership, socioeconomic status, sex, and body mass index. The results support the sensitization hypothesis in that exposure to marital conflict may influence an important facet of children's biological regulation, namely sleep.

Many years ago a farmer had a farm along the Pacific seacoast. He often hired workers to help him. Most people didn＇t want to work on farms along the Pacific Ocean because they were afraid of the terrible storms（暴风雨）.     

Trauma characteristics and sleep impairment among trauma-exposed children

Trauma-related sleep difficulties are quite common and their functional and clinical importance are increasingly recognized. High rates of sleep problems have been documented among trauma-exposed adults, particularly those diagnosed with posttraumatic stress disorder (PTSD); however, research with trauma-exposed children is relatively limited. Research specifically with child samples is critical due to the numerous developmental and functional implications that may result from sleep impairment. Characteristics of the traumatic event may play a key role in understanding sleep difficulties, yet, these associations are not well understood among trauma-exposed children. The current study therefore investigated whether aspects of the traumatic event (i.e., type, nature, chronicity, age of onset, removal from home, and complex trauma) were related to higher levels of sleep disturbances among 276 treatment-seeking children ages 6–18 years (M = 10.88, SD = 3.39; 63.4% female; 62.7% Black). Sleep problems were common in this sample. Domestic and community violence exposure were associated with higher levels of select sleep difficulties, as were interpersonal trauma, chronic trauma, a trauma that began early in life, and complex trauma. Nonetheless, type of trauma and characteristics of the traumatic event were largely unrelated to sleep problems on either caregiver’s or children’s reports. Removal from the home was not linked with sleep impairment. Although findings signify the relevance of sleep disturbances among trauma-exposed children, trauma characteristics may have limited influence on sleep problems.     

First-time mothers' selection of infant supine sleep positioning

The incidence of Sudden Infant Death Syndrome (SIDS) has decreased dramatically since the inception of the "Back to Sleep" campaign initiated by the American Academy of Pediatrics in 1992. However, that decrease has leveled off and many new parents cease to follow the recommendation to place their infants in the supine position for sleep between 1 and 3 months of age, the peak age for the incidence of SIDS. Shortened hospital stays for new mothers and the overwhelming amount of required patient teaching dictate the need to find the best method of instruction. The purpose of this study was to determine if a one-on-one teaching intervention improved the effectiveness of patient education and led to an increase in the desired behavior of placing the infant to sleep in the supine position. A quantitative experimental approach was used to examine the difference in compliance of supine infant positioning. Participants were drawn from a convenience sample of 61 primiparous women between the ages of 18 and 35 years with random assignment to either the experimental or control group. Compared to mothers in the control group, mothers in the experimental group demonstrated greater compliance in selecting supine sleep position in the first week home from the hospital and on the day of follow-up 6 weeks later. However, no difference in "usual position" was reported at 6 weeks and for the night previous to follow-up.     

Nap schedules and sleep practices in infant-toddler groups

This article describes and analyzes sleep-wake schedules and nap times in multiage infant-toddler groups through three case studies based on ethnographic research conducted in two Finnish day care centers. The study asks how day care centers and homes in collaboration can protect children’s biological sleep-wake rhythms and the physiological effectiveness of sleep. Data were derived through participant-observation in the groups, taped interviews with staff and parents, and sleep diaries kept by the parents. Findings show some of the complex interactions among family daily patterns, day care patterns, and sleep disturbances in very young children. The findings further show that major differences exist in day care practices regarding the quality of sleep and its physiological effectiveness. These differences are related to three issues: (1) whether the timing of naps in the multiage group is simultaneous or staggered in an age-appropriate and individually appropriate manner; (2) how efficiently the home/day care personnel communicate with one another; and (3) what is the awareness level of the day care staff about the significance of the sleep environment. The article further discusses the team aspect of protective practices, differences between caregivers and their differences in organizing work, as well as implications for further research and for caregiver training.

A twin-study of sleep difficulties in school-aged children

This study examines frequency, overlap, and genetic and environmental influences on sleep difficulties, which are understudied in school-aged children. The Sleep Self Report and the Children's Sleep Habits Questionnaire were completed by 300 twin pairs (aged 8 years) and their parents. Child report suggested more frequent sleep problems than parent report (e.g., regular sleep onset delay was reported by 45% of children and 17% of parents). Associations between most of the sleep difficulties were small but significant (e.g., r(s)=.16 for parent report of bedtime resistance and sleep onset delay). Twin correlations based on parent reports suggest greater genetic influence (M=50%) than those based on child self-report (M=18%). Possible rater effects should be considered when evaluating children's sleep problems.     

Reactivation of an old memory during sleep and wakefulness

In a series of four experiments, the effects of the reactivation of an old memory in different states of vigilance were investigated. Rats were trained to run in a six-unit spatial discrimination maze for food reward with low-level electrical stimulation delivered to the ear when they entered blind alleys. Twenty-five days after training, electrotactile stimulation was given to animals as a reactivating treatment just before a retention test. When the cuing treatment was given during wakefulness, retention performance was improved. When it was given in slow-wave sleep, it had no effect. When it was given in paradoxical sleep, performance was poorer. The use of control groups permitted an assessment of the specificity of the cuing effect in each case: Pretest presentation of the same stimulus did not modify performance when it had no cue value. Together, these results show that the effect of the reactivation of an old memory depends upon the vigilance state in which reactivation takes place. They suggest that reorganization of an old memory could be accomplished during paradoxical sleep.

Children's sleep regulation is linked to mothers’ sleep-related childhood experiences

The present research explored how mothers’ own childhood experiences are linked to their perceptions of their children's sleep regulation. It focused on collective sleeping; a practice used in the past in the Israeli kibbutz, and used a quasi-experimental research design to examine whether mothers who were raised in collective sleeping arrangements differed from mothers who were raised in home sleeping. Two typically developing cohorts: infants (n = 68; ages 9–15 months; M = 12.2, SD = 2.2) and preschool children (n = 113; ages 48–55 months; M = 51.5, SD = 1.85) participated in this investigation. Sleep regulation and temperament were reported for infants and children, whereas for mothers data were collected on separation anxiety and appraisal of the ecology in which they were raised. Collectively raised mothers evaluated their upbringing significantly more negatively than home-raised mothers, expressed higher separation anxiety with regard to an alternative caregiver, but were not different in their views of their child's sleep difficulties. For infants, it was maternal separation anxiety that contributed uniquely to the explained variance in maternal view of sleep regulation difficulties. For preschool children, it was maternal evaluation of own childhood ecology and child's temperament that contributed uniquely to the explained variance in maternal view of sleep regulation difficulties. These findings suggest that mothers’ representations of their sleep-related early experiences, rather than their childhood ecology in and of itself, influenced their perceptions about their child's sleep, which, in turn, affect child's sleep patterns. Implications to caregiving are discussed.     

Posttrial REM sleep: A critical period for consolidation of shuttlebox avoidance

Deprivation of REM sleep for 2 h immediately following shuttlebox avoidance training produced deficient retention at 24 h after initial training. REM deprivation beginning 2 h after training had no effect. REM sleep appears to be involved in consolidation of this learning.     

Sleepy and hostile: The effects of REM sleep deprivation on shock-elicited aggression

Two studies were conducted to assess the effects of rapid eye movement (REM) sleep deprivation on shock-elicited aggression. REM deprivation periods of 0, 24, 48, and 72 h were used in the first study, while 48-, 72-, 96-, and 120-h periods were used in the second study. Both studies indicated that increases in REM deprivation (up to 96 h) resulted in increases in the number of aggressive responses. A decrease was shown by the 120-h group. A drive-energization or motivational-effects model is suggested.
