Abstract
Perpetrators, victims and witnesses sometimes falsely deny events even though they truly experienced them, for various socio-emotional and motivational reasons. However, someone who initially denied a crime they witnessed, suffered or perpetrated might come forward with allegations and give testimony in court.
In this talk Dr Bücken will:
- Present field research examining how frequently such denials occur in interviews conducted at child protective services in the Netherlands
- Present lab-based experimental research investigating how false denials can affect memory-based testimony.
Using different experimental and statistical methods (e.g., ROC curve analysis, equivalence tests, minimum effects testing), she will show that false denials can negatively impact memory for interviews during which such denials occurred, but that memory for traumatic events remains largely unaffected.
