Impact of sleep on attention in primary school-aged autistic children: Exploratory cross-cultural comparison between Singapore and UK children.
Poor sleep is common in autistic primary-schoolers, yet its effect on attention is uneven—measure both before you plan support.
01Research in Context
What this study did
Chua et al. (2022) compared sleep and attention in autistic and neurotypical primary-schoolers.
They tested children in Singapore and the UK to see if culture changed the sleep-attention link.
Parents filled out sleep logs while kids took a 15-minute computer attention test.
What they found
Autistic children slept less and took longer to fall asleep than doctors recommend.
Yet attention scores were all over the map: some autistic kids scored high, some low, and culture mattered.
The team could not say poor sleep always hurts attention in autism.
How this fits with other research
Bergmann et al. (2019) pooled three trials and showed behavioural sleep training adds 24 minutes of sleep and cuts falling-asleep time by 18 minutes for autistic children. Beatrice’s data fit here: the same short sleep they saw can be fixed.
Hong et al. (2021) then delivered this training through Zoom to school-aged autistic kids and parents saw better sleep and calmer days. Beatrice’s work sets the stage: they mapped the problem; S et al. showed a practical fix.
Rothwell et al. (2025) also found attention differences between autistic and typical kids during a word game, but both groups learned equally well when vocabulary was matched. This matches Beatrice’s message: attention varies, but outcome depends on the task and support, not just diagnosis.
Why it matters
You cannot assume a tired autistic child will look inattentive. Check sleep first, then test attention directly. If sleep is short, try the bedtime routines that S et al. proved work. Track the child’s own baseline instead of comparing to norms.

03Original abstract
BACKGROUND: There is a growing body of research studying the impact sleep has on attention among typically developing (TD) children, but research is lacking among autistic children. AIMS: The present study aimed to explore, for the first time, differences in (1) attention, (2) sleep parameters among primary school-aged Singaporean autistic children (N = 26) and Singaporean TD children (N = 20), and with UK autistic (N = 11) and UK TD children (N = 16), and (3) the impact of sleep on attention. METHODS AND PROCEDURES: Actigraphy was used to objectively assess sleep, and a Continuous Performance Task was used to measure attentional domains. OUTCOMES AND RESULTS: There were inconclusive findings indicating that autistic children had poorer sustained attention than TD children. Although autistic children did not display more sleep difficulties than TD children, they showed shorter actual sleep duration (Singapore ASD = 7:00 h, UK ASD = 7:35 h, p < .01) and longer sleep latency (Singapore ASD = 30:15 min, UK ASD = 60:00 min, p < .01) than clinical recommendations. Sleep difficulties were also present among Singaporean and UK TD children. Both TD groups had less actual sleep duration than recommended (Singapore TD = 6:32 h, UK TD = 8:07 h). Singaporean TD children had sleep efficiency below recommended criterion (78.15%). Sleep impacted attention across all groups, but effects were different for autistic and TD groups. CONCLUSIONS AND IMPLICATIONS: The study highlighted the importance for practitioners and carers to adopt a child-centred approach to assessing sleep and attentional difficulties, especially among autistic children due to the high variability in performance within the group. The impact of cultural and school-setting differences on sleep was also raised.
