2019, Current BiologyCitation Excerpt :The extraordinary capabilities of locomotor control systems are illustrated by the ability of animals to traverse complex environments without much conscious effort. Sensory information obtained about surrounding obstacles can be used to modify stepping in a feedforward manner [1–3], allowing, for example, mountain goats to scale precarious rocky ledges while grazing or humans to walk through busy crowds without colliding into other people or objects. This relative ease of obstacle locomotor behaviors is facilitated by the ability to store information about an obstacle in working memory (WM) that can be used to coordinate the appropriate movements for avoidance.

2014, NeuroscienceCitation Excerpt :The “around one second” time to reaching for manipulation of a viewed object appears to be a “golden rule” for timing of visual sampling for adjustment/generation of a wide variety of movements. It was reported that, when walking in a cluttered environment, cats look 1.3 s ahead (Fowler and Sherk, 2003; Wilkinson and Sherk, 2005) and people look 0.8–1.2 s ahead (Grasso et al., 1998; Patla and Vickers, 2003; Land, 2006; Marigold and Patla, 2007). Also, people take 0.75 s to start steering a car after seeing a target (Land and Lee, 1994), articulating a sound after seeing a letter (rev. in Rayner, 1998), and 0.8 s to strike a key after observing a musical note (Furneaux and Land, 1999).
