Emotions are a complex phenomenon that entails a tricky problem regarding the measurement. To partially overcome this question, we assess emotions both using self‐report and measures commonly used in neuromarketing. This study assesses the accuracy of the recall after 4 months regarding two social advertising videos about female genital mutilation. Forty female participants were recruited. The skin conductance trend of the participants is different when viewing the two videos. The majority of participants (94.9%) reported that the two videos elicited different emotions (sadness for the first video and anger for the second one). Furthermore, according to arousal and valence model, these data are consistent with the literature that underlines the importance of psychophysiological indexes in measuring emotions and their associations with memory performances.

In this paper expert and non-expert consumers reactions about wine consumption are studied by means of traditional self-questionnaires and neuromarketing methods, as electroencephalography and eye-tracking. Data from self-questionnaires allow to identify the most import factors mediating wine evaluation, while data from electroencephalography show how non-expert consumers feel stressed by wine evaluation in comparison to expert ones. Eye-tracking data show how expertise mediates time spent to process visual elements on wine labels. These techniques can lead to a model enabling to better understand consumers evaluation about wine products.

The objective of the study was to evaluate effects of complexity on cognitive workload in a simulated air traffic control conflict detection task by means of eye movements recording. We manipulated two complexity factors, convergence angle and aircrafts minimum distance at closest approach, in a multidimensional workload assessment method based on psychophysiological, performance, and subjective measures. Conflict trials resulted more complex and time-consuming than no conflicts, requiring more frequent fixations and saccades. Moreover, large saccades showed reduced burst power with higher task complexity. A motion-based and a ratio-based strategy were suggested for conflicts and no conflicts on the basis of ocular metrics analysis: aircrafts differential speed and distance to convergence point at trial start were considered determinant for strategy adoption. Eye metrics measurement for online workload assessment enhances better identification of workload-inducing scenarios and adopted strategy for traffic management. System design, as well as air traffic control operators training programs, might benefit from on line workload measurement.
