Infant Locomotion (IMAGE) Association for Psychological Science Caption To study the relationship between visual proprioception and the development of wariness of heights in infants, Dahl and colleagues placed infants in a powered mobility device (upper left) and a moving room (upper right). They tested their wariness of heights using the crossing paradigm (study 1, lower left) and lowering paradigm (study 2, lower right). Credit Dahl, A., et al. (2013).
