“…Although these techniques enhance the amount of information retrieved, at least under some conditions (see Salmon, 2001, for a review), interviewers seldom know which props might be relevant, and need to avoid introducing props at times which would make them suggestive. In addition, analogue studies show that, when children interact with the prop items, showing as well as telling, accuracy decreases markedly, and that the effects on accuracy are even greater when young children are shown toys and models (Gordon et al, 1993;Salmon, 2001;Salmon, Bidrose, & Pipe, 1995;Salmon & Pipe, 1997;Steward & Steward, 1996;Thierry, Lamb, Orbach, & Pipe, 2005), presumably because young children are more vulnerable to suggestion and are less capable of representing their experiences using objects (DeLoache, 1995).…”
