“…As line junctions are also shown to be important for recognition of common objects (Biederman & Blickle, 1985; Dehaqani et al, 2016; Szwed et al, 2009), words (Lanthier et al, 2009; Szwed et al, 2009), letters (Lafontaine & Kolinsky, 2019; Lanthier et al, 2009), and geometrical figures (Kamenkovich & Skrandie, 2006; Shevelev et al, 2003), it is possible that humans also learn to make use of the information of line junctions in their neural representation for object categorization, in particular for the case of letters and words with which humans tend to develop a high level of perceptual expertise nowadays. These should also be clarified in future studies.…”

“…Line junctions indicate where edges and lines meet for defining the shape of two‐dimensional objects (e.g., letters and symbols), and help identify geons that give rise to three‐dimensional object recognition in a view‐invariant manner (Biederman, 1987). Empirically, humans recognize objects better when line junctions are preserved than removed with common objects (Biederman & Blickle, 1985; Dehaqani et al, 2016; Szwed et al, 2009), words (Lanthier et al, 2009; Szwed et al, 2009), letters (Lafontaine & Kolinsky, 2019; Lanthier et al, 2009), and geometrical figures (Kamenkovich & Skrandie, 2006; Shevelev et al, 2003). These advantages of recognizing objects when line junctions are present were also observed in animals, including pigeons and macaque monkeys (Gibson et al, 2007; Lazareva et al, 2008).…”

Previous studies have demonstrated that engaging in graphomotor activity for creating graphemes can enhance their subsequent visual discrimination. This suggests a positive influence of the motor system on visual learning. However, existing studies have emphasized the dominant hand, which is superiorly dexterous in fine-motor movements. This near-exclusive focus prompts the inquiry of whether the observed perceptual facilitation is a general characteristic of the motor system, or specific to pathways controlling the skilled over-trained dominant hand. Furthermore, the mechanistic underpinning of visual facilitation from graphomotor training (i.e., the individual contribution of motor activity, temporal evolution of the visual trace, variability of visual output) remain unclear. To address these questions, we assessed visual discrimination capabilities of healthy right-handed participants (N = 60) before and after graphomotor or visual training. Contrary to our initial expectation, graphomotor engagement with the non-dominant hand did not yield additional benefits to visual learning beyond those attainable through visual training alone. Moreover, graphomotor training with the non-dominant hand resulted in visual discrimination improvements comparable to those of dominant hand training, despite the inherent differences between hands in motor performance and in the amount of improvement in shape tracing throughout training. We conclude that the motor components of graphomotor activity may not be critical for visual learning of shapes through tracing activity. Instead, our results are in agreement with the symbolic theoretical account, suggesting that basic shape features required for discrimination can be acquired through visual inspection alone, providing a perspective on the improvements observed in prior studies.
