Presented is the first phase of the research project in which the authors try to establish the connection between personality characteristics and memory recall. They are trying to develop a model which could be helpful in predicting the validity of eyewitness testimony. First, personality characteristics were measured using Eysenck's personality test, then a short film about a physical attack and robbery was shown to the participants, and finally, one week later, the memory recall was checked. On the basis of data gathered it is impossible to predict the quality of eyewitness testimony satisfactorily. However, other interesting results were established: the participants high on extraversion and low on neuroticism were more reliable as witnesses, the level of accuracy of memory recall depended on the emotional stability, the participants with high neuroticism and psychoticism produced less accurate recall and the subjects with high psychoticism showed a weak response or smaller quantity of the recalled data.
