Current computerized tools allow detailed exploration of the structure and functioning of the "black box," i.e., human cognitive and affective systems as well as thought. This technology was used to study the visual perception of facially expressed emotions. Morphological transition from one canonical emotion to another led to the creation of a continuum of intermediary pictures, and the identification of perceived emotions by 65 normal subjects was measured. We call this application "MARIE" (in French: Méthode d'Analyse et de Recherche de l'Intégration des Emotions; Method of Study and Analysis of Integration of Emotions). Our study examined the relationship between the quantitative modification of the continuum and the quantitative variation of the responses. Standardization of graphs led to the assessment of the two parameters of a Laplace-Gauss curve, i.e., mean and standard deviation. It is argued that such a tool could be very useful in the clinical assessment of the emotional state of subjects and/or of patients.

AbstractWe studied the visual recognition of the facial emotions, on 20 chronic and institutionalized schizophrenics. They were paired in age, sex, educational level with a reference group. We used the MARIE battery which uses a binary pairing in a continuum of intermediate images. The recognition of the disgust is decreased followed by the fear. The surprise is the least overdrawn. The recognition of anger and the bipolar series (emotionemotion) is strictly identical to that of the witnesses.
Background: Alzheimer's sufferers (AS) are unable to visually recognize facial emotions (VRFE). However, we do not know the kind of emotions involved, the timeline for the onset of this loss of ability to recognize facial emotional expressions during the natural course of this disease and the existence of any correlation with other comorbid cognitive disorders. For that reason, the authors aimed to determine whether a deficit in facial emotion recognition is present at the onset of Alzheimer disease, distinctly and concurrently with the onset of cognitive impairment or is it a prodromal syndrome of Alzheimer's Disease before the onset of cognitive decline and what emotions are involved. A secondary aim was to investigate relationships between facial emotion recognition and cognitive performance on various parameters. Method: Single Blind Case-control study. Setting in Memory clinic. Participants: 12 patients, (AS) and 12 control subjects (CS) were enrolled. Measurements: Quantitative information about the ability for facial emotion recognition was obtained from Method of Analysis and Research on the Integration of Emotions (MARIE). The Mini Mental Status Examination (MMSE), the Picture Naming, the Mattis Dementia Rating Scale (DRS), and the Grober & Buschke Free and Cued Selective Reminding Test (FCSRT) tests were used to measure cognitive impairment. Results: We note that the AS have a problem with the visual recognition of facial emotions with existence of a higher threshold for visual recognition. The AS is less sensitive to the visual recognition cues of facial emotions.
