She has conducted several studies, with Prof. Gershon Ben-Shakhar, on the efficiency and validity of polygraph assessment of guilty knowledge. Dr. Gronau examined the efficiency of behavioral measures such as reaction times in the assessment of concealed information, along with their incremental contribution to psychophysiological measures (e.g., skin conductance responses) typically used in polygraph investigations. Dr. Gronau also conducts cognitive research in the field of visual attention and visual recognition, using both behavioral and neuroimaging measures.
