Drawing is a powerful communication tool. For people with complex communication needs, like people with aphasia (PWA), drawing can serve as an effective modality of augmentative and alternative communication, helping repair communication breakdowns and better participate in discourse with others. There is also emerging evidence that semantic drawing, or creating drawings that are representative of conceptual knowledge, may also help improve word finding in this population (Farias et al., 2006; Kinney et al., 2019; Taylor & Hough, 2013). However, the mechanism behind this restorative effect is not well established. While researchers posit that there is a link between semantic drawing and semantic activation, there is also not sufficient evidence to demonstrate that improvements in word retrieval are not due to the motor act of drawing, regardless of the semantic content present in these drawings. The purpose of this study was to explore the effect of non-invasive brain stimulation to the anterior temporal lobes (ATL), a cortical area thought to be responsible for semantic integration, on different drawings tasks. Neurologically intact young adults completed two drawing tasks (semantic drawing and visuospatial drawing) while they received anodal, cathodal, or sham high-definition transcranial direct current stimulation over the right ATL. To test a secondary aim, they also completed a picture association task. The stimulation condition did not predict performance on any of the experimental tasks, making it difficult to draw conclusions on the role of the right ATL in either type of drawing task or the picture association task. However, other significant relationships found in the data provide insights into the potential feasibility of a treatment approach for PWA involving semantic drawing. Limitations in the current research design and future directions will be discussed.
