Lpez explains that in her research she adapted a series of tests that where already known in the United States a country with a long history of work in the field of neuropsychology to the Spanish context, because "the neuropsychological tests cannot be extrapolated without adjustments from a context to another. The percentage of patients who suffer from head injuries that feign symptoms is nearly the same as that obtained by the American researchers.

The study carried out in the UGR also included a method which has become very popular recently due to several television programs: the lie detector, an instrument which registers the physiological responses of blood pressure, heart beat, breathing rate and galvanic skin response. Vilar Lpez used this equipment with a group of 80 Psychology students as the analogous group, that is, as no patient would admit being a simulator, a group of people without any disorders were asked to fake them in order to confirm the validity of the test. Furthermore, 54 actual patients were analyzed by the doctor. These patients belonged to different departments of the University Hospital Virgen de las Nieves in Granada.

The researcher explains that although the lie detector itself has no scientific rigor, it could be an efficient instrument if combined with other tools, as for example the tests that we have validated. Part of the results of her research were presented at the last International Neuropsychological Society and National Academy of Neuropsychology conferences the two most important organizations in the field of neuropsychology in the world and in the prestigious scientific journal Archives of Clinical Neuropsychology.
