“…Previous studies have demonstrated the flexible weighting of different goal‐ and means‐oriented processes with each weight changing depending on the internal and external constraints presented (Seegelke & Weigelt, 2018; Yoon et al, 2010; Borghi & Riggio, 2015). These findings are in contrast to studies that propose the technical reasoning hypothesis, a concept that fits within the framework of the reasoning‐based hypothesis (Mizelle & Wheaton, 2014). According to these series of hypotheses, tool‐use is not associated with knowledge about object manipulation (Jarry et al, 2013).…”

Tools and objects are associated with numerous action possibilities that are reduced depending on the task-related internal and external constraints presented to the observer. Action hierarchies propose that goals represent higher levels of the hierarchy while kinematic patterns represent lower levels of the hierarchy. Prior work suggests that tool-object perception is heavily influenced by grasp and action context. The current study sought to evaluate whether the presence of action hierarchy can be perceptually identified using eye tracking during tool-object observation. We hypothesize that gaze patterns will reveal a perceptual hierarchy based on the observed task context and grasp constraints. Participants viewed tool-objects scenes with two types of constraints: task-context and grasp constraints. Task-context constraints consisted of correct (e.g., frying pan-spatula) and incorrect tool-object pairings (e.g., stapler-spatula). Grasp constraints involved modified tool orientations, which requires participants to understand how initially awkward grasp postures can help achieve the task. The visual scene contained three areas of interests (AOIs): the object, the functional tool-end (e.g., spoon handle) and the manipulative tool-end (e.g., spoon bowl). Results revealed two distinct processes based on stimuli constraints. Goal-oriented encoding, the attentional bias towards the object and manipulative tool-end, was demonstrated when grasp did not lead to meaningful tool-use. In images where grasp postures were critical to action performance, attentional bias was primarily between the object and functional tool-end, which suggests means-related encoding of the graspable properties of the object. This study expands from previous work and demonstrates a flexible constraint hierarchy depending on the observed task constraints.

“…This relationship is likely true of ritual and communicative gestures that depend on accurate replication of arbitrary body movements 37 . There is debate on whether the learning of technical skills is more reliant on the mastery of physical affordances through individual practice 18 and how efficiently observed movements translate effectively to different bodies 38 – 40 and contexts 41 , 42 . This debate raises questions about the role of action observation in modern skill learning 43 and the importance of putative neurocognitive specializations for action observation in human evolution 5 .…”

Stone toolmaking is a human motor skill which provides the earliest archeological evidence motor skill and social learning. Intentionally shaping a stone into a functional tool relies on the interaction of action observation and practice to support motor skill acquisition. The emergence of adaptive and efficient visuomotor processes during motor learning of such a novel motor skill requiring complex semantic understanding, like stone toolmaking, is not understood. Through the examination of eye movements and motor skill, the current study sought to evaluate the changes and relationship in perceptuomotor processes during motor learning and performance over 90 h of training. Participants’ gaze and motor performance were assessed before, during and following training. Gaze patterns reveal a transition from initially high gaze variability during initial observation to lower gaze variability after training. Perceptual changes were strongly associated with motor performance improvements suggesting a coupling of perceptual and motor processes during motor learning.
