ABSTRACT
In verbal communication, affective information is commonly conveyed to others through spatial terms (e.g. in “I am feeling down”, negative affect is associated with a lower spatial location). This study used a target location discrimination task with neutral, positive and negative stimuli (words, facial expressions, and vocalizations) to test the automaticity of the emotion-space association, both in the vertical and horizontal spatial axes. The effects of stimulus type on emotion-space representations were also probed. A congruency effect (reflected in reaction times) was observed in the vertical axis: detection of upper targets preceded by positive stimuli was faster. This effect occurred for all stimulus types, indicating that the emotion-space association is not dependent on sensory modality and on the verbal content of affective stimuli.

Notes
1. Even though we tried to use an equivalent number of male and female non-linguistic vocalizations, our stimuli set contained more female vocalizations as our main selection criterion involved choosing the vocalizations with the highest emotion recognition rates (female vocalizations presented higher recognition rates for the emotions – Vasconcelos et al., Citation2017). However, no significant effects were expected as a function of speaker's gender: Cattaneo et al. (Citation2014) found no differences in line bisection when participants were listening to a female vs. male vocalization.
