How Relevant are Incidental Power Poses for HCI?
summary
Replication attempts test whether incidental expansive postures change feelings or risk taking: first study has 44 participants tapping targets on a wall display and measures self-reported felt power; second has 80 participants playing the Balloon Analog Risk Task on a large touch table while resting arms. Bayesian analyses show little to no effect of posture on felt power or risk taking, but expansive postures increase physical discomfort, so UI-induced postures are unlikely to meaningfully shift behavior.
