“…In spite of the positive association between nap duration and adiposity over time found in our study, we caution interpreting this as evidence to support limiting nap duration in toddlers, especially because nap(s) may be beneficial to other health and development outcomes, such as reduced stress levels, 51 improved motor skill learning, 52 and better cognitive function. 53 Therefore, it may also be important for future studies to identify the ideal nap duration in young children for optimal health, growth, and developmental outcomes.…”

Summary Background The associations between sleep characteristics and adiposity in children under three years are not fully understood yet. Objective The objective of the study is to examine the cross‐sectional and prospective associations between sleep characteristics and adiposity in toddlers over a 12‐month period. Methods Participants were 202 toddlers from the GET‐UP! Study. Sleep duration, sleep timing, and sleep variability were assessed using 24‐hour accelerometry for seven consecutive days. Height and weight were measured, and BMI z scores were calculated. Linear mixed models were performed to examine the cross‐sectional and prospective associations between sleep characteristics and adiposity, with adjustments for clustering effects and demographic factors. Results Total sleep duration was negatively associated with higher adiposity cross‐sectionally (B = −0.12; 95% CI: −0.23, −0.01; .033) but not prospectively (B = 0.01; 95% CI: −0.13, 0.10; .843). Nap duration was prospectively associated with higher levels of adiposity (B = 0.41; 95% CI: 0.14, 0.68; .003). Sleep variability and sleep timing were not associated with concurrent or subsequent adiposity. Conclusion Although sleep duration is an important factor associated with obesity in toddlerhood, the potential effects of different types of sleep duration may vary. While longer total sleep duration may protect children from increasing adiposity, longer nap duration seems to be risk factor. As evidence in this age group is scarce, more research is needed to confirm this finding.

“…The beneficial effect of napping on explicit memory has also been reported in children between 3 and 6 years old 148 . In this age group, the mean nap duration was documented as 77 +/-18.7 min, and napping had a clear benefit on memory retention, with children forgetting significantly more items after staying awake than following a nap.…”

“…that makes identification more difficult. A useful method to study visual priming is the use of an ascending paradigm, where the difficulty of recognition is manipulated by gradually increasing the spatial frequency at which the visual images of the stimuli are presented, starting from very low spatial frequencies (at which the stimulus is very difficult to recognize) until the maximum spatial frequency (at which the visual image is complete; Giganti et al ., ; Vannucci et al ., ; Viggiano et al ., , , ).…”

Insomniacs often report memory and concentration problems, but these complaints have not been consistently supported by performance measurements. Furthermore, while the majority of studies have addressed explicit memory, few have investigated the implicit domain, and very little is known concerning other types of implicit memory besides procedural memory, such as priming. Thus, the purpose of the study was to investigate priming effect for visual stimuli in insomniacs and good sleepers. Twenty-three insomniacs and 20 good sleepers performed a visual priming task in which they were asked to name new and old pictures presented at nine ascending levels of spatial filtering. Both neutral and sleep-related stimuli were used, as previous research evidenced an attentional bias for sleep-related stimuli. Visual priming effect was observed in both groups, suggesting that poor sleep quality does not affect this type of implicit memory. However, the identification process in insomniacs is influenced by the nature of the stimulus to identify: insomniacs recognized both new and old sleep-related stimuli at lower spatial frequencies compared with good sleepers. The tendency to selectively attend to sleep-related stimuli may influence top-down processes occurring during identification of filtering stimuli, by determining a pre-allocation of attentional resources and facilitating identification processes even when sensorial information is scant. Differences in the identification processes of sleep-related stimuli compared with neutral ones should be carefully taken into account as possible pre-clinical markers of insomnia in poor sleepers.

The Effect of a Daytime Nap on Priming and Recognition Tasks in Preschool Children

Abstract: A positive role of sleep in explicit memory consolidation, similar to the one observed in the adult, was detected in our sample of preschool children. In contrast, our data suggest that implicit perceptual learning, involved in priming tasks, does not benefit from sleep.
