...We used a custom inclinometer (Li & Durgin, 2011a) to measure hand orientation relative to a horizontal baseline, using the central axis of the hand to represent the response (Durgin, Li & Hajnal, 2010)....

...Moreover, free hand measures also have been found to be tightly correlated with verbal measures (Li & Durgin, 2011a)....

...The gesture was conducted with the hand occluded behind a screen and was measured with a custom inclinometer (Li & Durgin, 2011a)....

...Li and Durgin (2011a) showed that free hand manual matching techniques were correlated with verbal reports (see also Li & Durgin, 2011b)....

...…that perceived gaze angles are exaggerated and that perceived egocentric distances are foreshortened, as we have mentioned above, there is no actual contradiction because action can be calibrated to visual experience (Harris, 1963; Held & Freedman, 1965; Li & Durgin, 2012b; Rieser et al., 1995)....

...Note, in contrast, that if an L-shape configuration (1.5 m x 1.5 m) were placed on the ground 9 m away, and the direct comparison of the frontal and depth legs were requested, participants might tend to switch to a judgment based on estimating the optical slant (Li & Durgin, 2012a)....

...The angular expansion hypothesis has been successfully applied to findings regarding the perception of egocentric extents, vertical extents and slant whereas other theories tend to have a more limited scope (see Li & Durgin, 2012a)....

...One, associated with shape tasks such as the aspect ratio task developed by Loomis et al. (1992), is quite a large anisotropy that seems to be related to the misperception of local optical slant (Li & Durgin, 2010, 2012a; Loomis & Philbeck, 1999; Loomis et al., 2002)....

...…hypothesis The angular expansion hypothesis is based on evidence that two angular variables, optical slant and the gaze declination, are perceptually exaggerated in the range most relevant in action space (Durgin and Li, 2011; Durgin et al., 2010; Li and Durgin, 2009, 2010, 2012a; Li et al., 2011)....

...The idea of perceptual calibration (see Lackner and DiZio 2000 for review) indicates that accurate (or efficient) actions do not necessarily require accurate perception but can be based on correct expectation (see also Powers 1973)....

...Indeed, observed arm trajectories and end postures in hand reaching actions are typically quite constrained (Jeannerod 1988) compared to the possible degrees of freedom of arm movement (Cruse and Bruwer 1987)....

...In research on space perception, action based measures are often used in studying perceived distance and slant (e.g. Bingham and Pagano 1998; Gibson and Cornsweet 1952; Loomis et al. 1992; Norman et al. 2009; Rieser et al. 1990)....
