<span class="ldml-entity">the People</span> asked the interviewer to provide the following information: <span class="ldml-parenthetical">(1)</span> how many children the interviewer had forensically

class="ldml-parenthetical">(3)</span> how many times the interviewer had testified in <span class="ldml-entity">a court</span> of law; <span class="ldml-parenthetical">(4)</span> whether children commonly tell other children about abuse before telling adults; <span class="ldml-parenthetical">(5)</span> whether children typically say different things to the interviewer than <span class="ldml-entity">they</span> do to responding officers or <span class="ldml-entity">Department of Human Services</span> workers, or when testifying at trial; <span class="ldml-parenthetical">(6)</span> whether specific details on which the children's stories differed—such as whether C.O. was present when A.M. was assaulted—were core or peripheral; <span class="ldml-parenthetical">(7)</span> what <span class="ldml-quotation quote">"reproduction"</span>—whereby child victims demonstrate inappropriate touching on their own bodies—is; <span

data-sentence-id="6976" class="ldml-sentence"><span class="ldml-entity">The trial court</span> allowed the interviewer to answer all of these questions except for two: the question regarding the gestures A.M. used to reproduce the event, ruling that this evidence was cumulative because the jury would witness A.M.'s actions when it watched the videotaped interview, and the question regarding why interviewers look for signs of reproduction, ruling that this called for expert testimony.</span></p><p data-paragraph-id="7385" class="ldml-paragraph "><span data-paragraph-id="7385"

data-sentence-id="22827" class="ldml-sentence">The interviewer also described how <span class="ldml-entity">she</span> conducts an interview with a child victim, including that <span class="ldml-entity">she</span> builds rapport with the child, tests the child's memory, directs the child to answer questions honestly, and usually asks open-ended, not leading, questions.</span> <span data-paragraph-id="22370" data-sentence-id="23086" class="ldml-sentence">This description of basic interview protocol did not amount to expert testimony, either.</span> <span data-paragraph-id="22370" data-sentence-id="23175" class="ldml-sentence">While an ordinary person may not be able to articulate a specific protocol for conducting interviews, <span class="ldml-entity">she</span> would know that in order to obtain accurate information from a child, it is important to make the child feel comfortable, evaluate whether the child remembers the events in question, and make sure the child understands the importance of the truth.</span> <span data-paragraph-id="22370" data-sentence-id="23529" class="ldml-sentence">As for the distinction between

<span data-paragraph-id="22370" data-sentence-id="23857" class="ldml-sentence">Significantly, in testifying about her professional background, the interviewer did not draw any inferences about the

children before <span class="ldml-entity">they</span> tell adults was expert testimony.</span> <span data-paragraph-id="24383" data-sentence-id="24663" class="ldml-sentence"><span

data-paragraph-id="24383" data-sentence-id="25237" class="ldml-sentence">Because an ordinary person who interacts with children can recognize these behaviors without additional training or specialized
