More than just ambivalence: the perception of emotionally ambiguous words on the spaces of origin and activation indexed by behavioural and webcam-based eye-tracking correlates

Abstract

AbstractWhen we think about emotional ambiguity, we usually think about the feeling of ambivalence. However, in a recently proposed model, ambiguity might also be present in different emotional spaces, such as origin (dimensions of automaticity and reflectiveness) and activation (arousal and subjective significance) as proposed in the basics of dual-process theories. In two experiments, we checked for behavioural and psychophysical differences in processing words of origin and activation ambiguities while completing an emotionality rating task. In Experiment 1, we assessed emotionality ratings and reaction times; in Experiment 2, we used a webcam-based eye-tracking measurement to assess the number and mean duration of fixations. We found significant effects for words differing in origin and activation: the emotionality ratings increased within the intensity of origin ambiguity but decreased within the intensity of activation ambiguity; more and longer fixations were registered for words of higher origin ambiguity; and gradually fewer and shorter fixations were registered within increases in activation ambiguity. We found that the ambiguities on spaces of origin and activation produced their own main effects, but they also factored significantly into the interaction, modifying each other’s results. Our study is the first to show specifics of the perception of ambiguous stimuli on spaces other than valence.
