Anatomically-neutral dolls: their effects on the memory and suggestibility of 4- to 6-year-old eyewitnesses.

The purpose of this investigation was to compare the amount and accuracy of details provided in the eyewitness accounts of preschool-aged children interviewed exclusively with a verbal interview against those interviewed with anatomically-neutral dolls in addition to a verbal interview. Forty-four children, aged 4 to 6 years, were paired up and assigned as participants or observers for an event they engaged in with a confederate. Children's memory was assessed afterwards by (a) The Step-Wise Interview (Yuille, Hunter, Joffe, & Zaparniuk, 1993); (b) the Step-Wise Interview and big dolls; or (c) The Step-Wise Interview and small, detailed dolls and props. Three leading questions were incorporated into the interviews. Results indicated no main effect of interview type on the overall amount or accuracy of the children's accounts. No main effects for interview type or participant versus observer condition were observed for the leading questions. Relative to 4-year-olds, 5-year-olds recalled a greater number of overall details and were more accurate in their accounts with both types of dolls. Females were more accurate than males in their accounts with the small detailed toys and props. Implications for the use of anatomically-neutral dolls in child sexual abuse investigations are discussed.
