This paper explores the possible relations between Reaction Times (RT) and Index of Productive Syntax (IPSyn) scores in preschool children. Nineteen children participated and were categorized into two groups; low and high Mean Length of Utterance (MLU). An auditory plus visual looking-while-listening task was conducted and eye gaze was tracked. Language samples from a previous study collected as children played with their mothers and a standard toy set were used to obtain IPSyn scores. Three hypothesis were tested; children with shorter RT will have higher IPSyn scores regardless of MLU; the noun phrase subscale of IPSyn will be related to RT in the low MLU group and not the high; the verb phrase subscale of the IPSyn will not be related to RT in the low MLU group but will be in the high MLU group. Results revealed no significant relations between RT and IPSyn scores .
