Memory implantation studies are also similar to recovered memory therapy in the way that they involve an authoritative figure claiming to know that the event actually happened and applying pressure on the participant/patient to remember. Memory implantation techniques in general also illustrate how people can relatively easily come to remember things that actually never happened. This poses a big problem for criminal confessions resulting from suggestive questioning by police and others and also for the accuracy associated with eyewitness memory. It has been argued that memory implantation studies are not applicable to real life memories of trauma such as childhood sexual abuse. As it is not ethical to try to implant false memories of sexual abuse researchers have tried to get around this by choosing other events that are seen as negative but not traumatic. Being lost in a shopping mall for example would be a negative experience for most children. Hyman and colleagues used memory implantation techniques with emotional events such as a specific birthday party (positive) and being hospitalized overnight (negative). They found that using emotional events did not change the rate of false memory creation significantly compared with other studies. Research with children In 1998 Herrmann and Yoder published an article arguing for the cessation of memory implantation research with children. The criticisms referred to several studies investigating the suggestibility of children written by Ceci and colleagues. Herrmann and Yoer argue that the methods used can have negative implications for the children used such as lessen their respect for authority, be damaging for their concept of self (feel incompetent when it is pointed out that their memories are wrong) and cause stress. This article created much debate and several commentaries to the article were published in the same June edition of the journal Applied Cognitive Psychology together with the original article. One of these was written by Ceci, Bruck and Loftus who disagree with the statements in Herrmann and Yoder's article. According to these authors there is no evidence that any children have been harmed in a memory implantation study and until such evidence exists there is no reason to stop using these techniques with children as long as it produces good research. Ornstein and Gordon also replied to Herrmann and Yoder's article saying that although people conducting research with children have an ethical responsibility there is much to be gained from memory implantation research and the
