Carlo Caltagirone's Testimony (English)
Summary of Carlo Caltagirone's Testimony
- Carlo Caltagirone is a medical specialist in neurology and psychiatry and a professor at the University of Rome Tor Vergata. In addition he is also the scientific director of a research institute run by the foundation of Saint Lucia where Caltigirone does research on cognitive function.
- Caltagirone was asked to consult on Amanda Knox and the possibility of her having false memories with respect to the statements she gave the police on November 5th 2007.
- Caltagirone met Knox on one occasion at the prison and spent about three hours talking to in March of 2009 (originally he states two hours to two hours and forty-five minutes in the winter of 2008 but later changes that).
- His assessment of Knox was that in his opinion Knox's cognitive functions are very good and typical of a young girl who is very ductile.
- Caltagirone believes that it is possible Amanda Knox had a false memory.
- Situations that increase the probability of a test subject having a false memory include prolonged pressure and tension.
- Amanda Knox is estimated to have spent about 42 hours of combined interrogation and time spent at the police station between November 2 and November 6th when she was arrested.
- Mignini asks about the other friends of Meredith who spent the same or more time with the police over the same period of time and their propensity for false memories and Caltagirone responds that they also been susceptible to having had false memories.
- Judge Massei asked Caltagirone why Amanda Knox would be anymore stressed about talking to the police than the other roommates or Meredith's friends. Caltagirone responded that he didn't believe there was anything about Knox that was specific to her and that everyone involved would have undergone a server amount of stress.
- Caltagirone was asked if lying causes stress and he confirmed that it does.
- Mignini asked Caltagirone about the November 4th incident when Knox was at the cottage with the other roommates to examine the knives and Knox went from being absolutely normal to crying and putting her hands to her ears.
- Carlos Dalla Vedova objected to this question but the question is allowed.
- Caltagirone responds that he cannot comment since he was never made aware of this specific incident.
- Mignini asks about Amanda Knox's behavior at the police station on the evening that the body was discovered and how the factors into Caltagirone's analysis that Knox was under a lot of stress. Caltagirone responds that the behaviour was incongruous with the situation but that Knox's behavior was in fact proof of the great emotional stress Knox was experiencing. That the behavior was an attempt by Knox to defend against the reality of what had happened.
- Caltagirone is asked about drug use and the impact it would have memory formation and he says it would depend on the quantity used and frequency of use but that drug use does not substantially affect memories. Returning to the subject he says drug use can alter memories both in how we form memories and how we recall them.
- Asked if drug and alcohol use increases tendency for violent behaviour Caltagirone responds that it depends on the situation.
- Caltagirone is asked a question about a specific statement by Amanda Knox and responds that his analysis did not get into the merits of any of Knox's individual statements.
- Caltagirone was asked if he considered that Knox was not requested at the police station on November 5th but rather only Raffaele Sollecito and that Knox came of her own volition. Caltagirone responded that while that was true that someone she was emotionally involved with was requested was itself stressful.
- Caltagirone was asked what material he had available and he said the written statement and some of the transcripts of Knox talking to family. He ends his statement with in short, the material that was provided to me by Amanda's lawyers.
- During Amanda Knox's first meeting with her mother (November 10) while in prison Knox told her mother that she felt horribly for Patrick because he had nothing to do with it. Caltagirone is asked if Amanda Knox had previously accused Patrick because she had a false memory how would that explain this statement. Caltagirone responded that he did not want to comment on that but then after some back and forth said it is possible for people to oscillate between real and false memories.
- Carlo Pacelli followed up with if so then why did Knox tell her mother but not her lawyers, the prosecutor, or the police. Amanda's lawyers object to this question.
- Caltagirone is asked if someone is on drugs and commits violence can that lead to a false memory. Caltagirone responds that someone could have dissociation and posttraumatic amnesia.
