From: In search of rules behind environmental framing; the case of head pitch
Incidence of stylised peaks [for examples see Fig. 1] (blue symbols), troughs (green symbols) and fixations (red symbols) in head pitch over time in 3 participants operating in 3 different environments (see Fig. 3). Sections of the graphs where there no data are shown correspond to periods where the changes in head pitch did not correspond to the identified stylised behaviour (see text)
