“…The fact that 10-month-olds found these featural changes salient is not unexpected, as it simply matches previous findings with adults (Loucks & Baldwin, 2009) and infants (Loucks and Sommerville, under review). This sensitivity is likely a key step towards gaining a functional understanding of other’s action.…”

“…Processing of others’ behavior is selectively focused on analyzing the features of action, such as how a hand contacts an object, in adulthood (Loucks & Baldwin, 2009) and infancy (Loucks & Sommerville, under review). These results indicate that one possible reason why infants are biased to selectively attend to featural information is that they are beginning to process action with respect to its functional consequences.…”

“…Recent evidence suggests that action discrimination shares processing similarities with face discrimination (Loucks & Baldwin, 2009). In face discrimination, people make use of distinct sources of featural and configural face information (see Maurer, Le Grand, & Mondloch, 2002, for a review).…”

Recent evidence suggests adults and infants selectively attend to features of action, such as how a hand contacts an object. The current research investigated whether this bias stems from infants’ processing of the functional consequences of grasps: understanding that different grasps afford different future actions. A habituation paradigm assessed 10-month-old infants’ (N = 62) understanding of the functional consequences of precision and whole-hand grasps in others’ actions, and infants’ own precision grasping abilities were also assessed. The results indicate infants understood the functional consequences of another’s grasp only if they could perform precision grasps themselves. These results highlight a previously unknown aspect of early action understanding, and deepen our understanding of the relation between motor experience and cognition.

“…Loucks and Baldwin (2009) created sets of video triads that included a standard-action video, a video altered solely in featural information, and a video altered solely in configural information. Featural changes were modifications in the local detail of the action performed, with no alteration of the global spatial trajectories of body parts.…”

In this paper, we compare responses of deaf signers and hearing non-signers engaged in a categorization task of signs and non-linguistic human actions. We examine the time it takes to make such categorizations under conditions of 180-degree stimulus inversion and as a function of repetition priming, in an effort to understand whether the processing of sign language forms draws upon special processing mechanisms or makes use of mechanisms used in recognition of non-linguistic human actions. Our data show that deaf signers were much faster in the categorization of both linguistic and non-linguistic actions, and relative to hearing non-signers, show evidence that they were more sensitive to the configural properties of signs. Our study suggests that sign expertise may lead to modifications of a general-purpose human action recognition system rather than evoking a qualitatively different mode of processing, and supports the contention that signed languages make use of perceptual systems through which humans understand or parse human actions and gestures more generally.

“…Another possibility would be that the important information for recognition is distributed across time and space and participants are intrinsically variable in their efficiency in accessing such information (Pollick, Lestou, Ryu, & Cho, 2002). Both these explanations suggest that the information available to observers to make their decisions varies, and thus so does performance (Loucks & Baldwin, 2009;Pollick & Paterson, 2008). However, another possible source of variability in recognizing biological motion could be the ability of the observer, and in this chapter we will explore this possibility.…”

Many discussions of biological motion perception involve a description of observers’ attunements for recognizing gender, emotion, action, and identity from point-light displays. This chapter describes an often-neglected determinant of biological motion perception: the role of expertise. First, the authors describe how variability among observers is essential for developing a comprehensive theory of biological motion perception. Then, they describe how the distributed network of brain areas devoted to biological motion perception provides an opportunity for this brain network to be applied to new tasks and environments.
