The current study assessed the impact of parents' dialogical storybook reading on their children's receptive vocabulary and reading attitudes. Forty parents and their preschoolers participated in the study. Parents were randomly assigned to experimental or control groups. The experimental group received dialogical storybook reading training. Children's receptive vocabulary and reading attitudes were measured before the dialogical storybook reading training and seven weeks after the training. Experimental group children showed significant increases in receptive vocabulary and reading attitude scores. There was no relation between reading attitude and receptive vocabulary development.
