IntroductionOccupational therapy handwriting studies have shown cognitive instructional techniques are effective methods to assist beginning or challenged handwriters. However, information about how children's cognitive (thinking) skills impact their handwriting development is scarce. This study examined the cognitive strategy efficiency of early learners while writing the alphabet‐letters from memory.MethodsParticipants included 408 mainstream children in their first two years of formal schooling (Year 1 and Year 2). Children were asked to write the 26‐lowercase alphabet‐letters from memory. Data were collected using alphabet‐letters generated by the children and observation of their cognitive strategy use while writing. The measurement tool employed was the Perceive, Recall, Plan, and Perform (PRPP) System of Task Analysis (Stage Two).ResultsThe results found that Year 1 and Year 2 children had difficulties applying cognitive strategies across all four PRPP quadrants while writing the lowercase alphabet‐letters from memory. Application of the cognitive strategies from the Plan and Recall quadrants showed the most inefficiencies. The lowest PRPP subquadrant scores were observed in Evaluating, Recall Facts, Sensing, and Programming. Except for the Attending subquadrant and the descriptor ‘Regulates’, Year 2 children were significantly better than Year 1 children at applying cognitive strategies from all other PRPP quadrants and subquadrants.ConclusionThe findings provide beginning evidence that efficient use of cognitive strategies from all four PRPP quadrants is important for children achieving proficiency in accurate and automatic alphabet‐letter‐writing skills. Recommendations for occupational therapy handwriting assessment and intervention are provided.Plain Language SummaryResearch suggests that occupational therapists can best help children with handwriting difficulties by using a cognitive approach. This approach involves instructing children how to form letters correctly, encouraging self‐evaluation, and providing opportunities to practice handwriting. However, the cognitive (thinking) skills required for children to write alphabet‐letters accurately are not well understood. To investigate this, a study was conducted on 408 mainstream children in their first two years of formal schooling (Year 1 and Year 2). The study examined how accurately the children could write lowercase alphabet‐letters from memory and which cognitive skills they used to do so. The cognitive skills investigated were related to attention, perception, recalling, planning, and performing. The assumption tested was that mistakes in correctly writing alphabet‐letters could be attributed to difficulties in using these cognitive skills effectively. The study found that Year 1 and Year 2 children made errors in over half of the 26‐lowercase alphabet‐letters they wrote. The cognitive skills, which scored the lowest were children's ability to evaluate their writing, recall how and where to write letters, gather information from their vision, and think carefully to ensure accuracy while writing. This implied that these thinking skills had the most impact on the children's ability to write alphabet‐letters correctly. More research is needed to confirm these findings and determine the reliability of the tool used in this study to measure the children's thinking skills.
