The startle response has been extensively studied in basic and applied contexts, using measurement instruments that, however, suffer from certain limitations. In this regard, near-infrared spectroscopy (NIRS) has shown good results by measuring emotional response and stands as a method that could overcome such limitations. This technique consists of measuring the hemodynamic response, in terms of oxygenated and deoxygenated hemoglobin, in the forehead and the cerebral cortex. The aim of the present study is to assess the startle response by NIRS on the forehead. For this purpose, the hemodynamic response of 12 subjects was registered in two conditions: neutral, in which they observed images without emotional content, and startle, in which this reaction is generated by a strong sound. The results showed significant differences in the hemodynamic response of the forehead, observing a greater hemodynamic response in the startle condition. In this way, NIRS seems to be a suitable method to assess anxiety-related emotional reactions, and can be a useful tool in basic and applied contexts.
