- Abstract
the valence and arousal scales of the Self-Assessment Manikin (SAM), which provide a subjective cognitive appraisal of different emotional dimensions. However, cognitive assessment ability in patients with acquired brain injury (ABI) may be compromised. Consequently, their emotional responses measured by self-report may be inconsistent. In these cases, the assessment should include complementary techniques, such as peripheral physiological measures empirically validated for the study of emotions. Method: We evaluated 36 patients with ABI and 33 healthy controls. Both groups watched pleasant, unpleasant and neutral images from the International Affective Picture System (IAPS) and rated them using SAM valence and arousal scales, while their peripheral physiological responses, consisting of skin conductance response (SCR) and heart rate (HR), were recorded. Results: In self-report measures, patients with ABI evaluated valence differently, regardless of stimuli, compared to controls. Regarding the arousal scale, patients with ABI reported feeling more aroused when compared to controls, except in unpleasant stimuli. However, the results obtained in the physiological assessment are not consistent with those of the cognitive assessment, as they showed lower reactivity to stimuli regardless of their emotional condition. Conclusion: These results show that patients with ABI have more difficulty in making a coherent assessment of their physiological arousal. For this reason, the simultaneous use of psychophysiological measures is highly recommended.
