Visual and non-visual cues in the perception of linear self motion

Laurence R. Harris, Michael Jenkin, Daniel C. Zikovitz
2000 Experimental Brain Research  
We discuss this dominance of the physical cues in determining the perceived distance of self motion in terms of capture by non-visual cues.  ...  Surprisingly little is known of the perceptual consequences of visual or vestibular stimulation in updating our perceived position in space as we move around.  ...  Doug Crawford, Fara Redlick and Carolee Orme made useful comments on early versions of this manuscript and Agnieszka Kopinska helped with the statistics.  ...

Human locomotion in languages: Constraints on moving and meaning

Barbara C. Malt, Eef Ameel, Mutsumi Imai, Silvia P. Gennari, Noburo Saji, Asifa Majid
2014 Journal of Memory and Language  
To help understand what constrains word meaning and how variation arises, we examined name choices in English, Dutch, Spanish, and Japanese for 36 instances of human locomotion.  ...  These findings, considered along with naming patterns from other domains, suggest recurring principles of constraint and variation across domains.  ...  Wolff (Eds.), Words and the mind: How words capture human experience (pp. 29-57).
