Attachment is the emotional bond between children and their caregivers (parents or otherwise). Infants and young children usually have more than one selective attachment, and all of these attachment relationships, including those between children and teachers, have important effects on cognitive and social development. Secure attachment to a preschool teacher may help children to improve their preschool experience. Recent studies suggest that the adverse effect of inadequate preschool experiences can lead to skill deficiencies that mimic the effects of basic cognitive deficits. This study evaluates the relationships among attachment to preschool teachers, school readiness, and the risk for developing learning difficulties in preschoolers using three measures: the School Readiness 4-5 battery, the Precocious Identification of Learning Difficulties, and the Attachment Q Set. This study examined 152 preschoolers. The results showed that attachment to preschool teachers is related to linguistic development level, the psychomotor skills involved in school readiness, and learning difficulty risk.
