Abstract
Our previous research showed that vertical vection could modulate human mood. We further examined this possibility by using memory recognition task of positive, negative and neutral emotional images with high and low arousal levels. Those images were remembered accidentally while the participants did visual dummy task, and later presented together with novel images during vertical vection-inducing or neutral visual stimuli. The results showed that downward vection facilitated the recognition of negative images and inhibited the recognition of positive ones. These modulations of incidental memory task provide an additional evidence for vection influence on cognitive and emotional processing, and also provide a new paradigm that can be used in future vection and embodied cognition research.
Highlights
Embodied cognition research has shown that certain body postures and movements can affect cognition and memory (Lakoff and Johnson, 1980; Riskind and Gotay, 1982; Riskind, 1983; Klatzky et al, 1989; Stepper and Strack, 1993; Goldstone and Barsalou, 1998; Barsalou, 1999)
Hit Rate (HR) and False-Alarm Rates (FAR) were normalized for each subject so that 100% corresponded to the maximal number pictures recognized for all five types of images
Vection direction and emotional valence interaction was significant at F(2,27) = 4.26, p < 0.05, η 2p = 0.24 with stimuli moving up facilitating recognition of negative images and inhibiting positive ones
Summary
Embodied cognition research has shown that certain body postures and movements can affect cognition and memory (Lakoff and Johnson, 1980; Riskind and Gotay, 1982; Riskind, 1983; Klatzky et al, 1989; Stepper and Strack, 1993; Goldstone and Barsalou, 1998; Barsalou, 1999). Recognition Memory and Vertical Vection responses such as electrodermal activity, heart rate or blood pressure can be modulated by moving environments inducing vection and/or motion sickness in healthy subjects (Stout and Cowings, 1993; Aoki et al, 2000 and references therein). Considering these previous research we can hypothesize that vection might alter our emotion state and the underlying affective responses. We conducted an experiment in which we provided participants with image recognition task during the continuous induction of vertical (upward/downward) vection
