Tests on spatial aptitude, in particular Visualization, have been shown to be efficient predictors of the academic performance of Technical Drawing stu-dents. It has recently been found that Spatial Working Memory (a construct defined as the ability to perform tasks with a figurative content that require si-multaneous storage and transformation of information) is strongly associated with Visualization. In the present study we analyze the predictive efficiency of a bat-tery of tests that included tests on Visualization, SpatialWorking Memory, Spatial Short-term Memory and Executive Function on a sample of first year engineering students. The results show that Spatial Working Memory (SWM) is the most important predictor of academic success in Technical Drawing. In our view, SWM tests can be useful for detecting as early as possible those students who will require more attention and support in the teaching-learning process.

This paper discusses the redefinition of the function of freehand drawing in the design process in view of intuitive digital media. It sets forth an interpretive analysis of an experiment with drawing on opaque tablets, carried out with a group of students of the Instituto de Arquitetura e Urbanismo da Universidade de São Paulo. After a brief review of the current debate on freehand drawing and the advent of digital media, we examine the experiment as a possible way to elicit facts that may contribute to the discussion. To this end, our research has concentrated on the intuitive use enabled by existing digital media. It is our intention that this empirical approximation becomes a pilot experiment for the use of digital tablets in the process of construction the gaze of the student in Architecture and Urbanism as a reflection on the different cognitive dimensions that constitute the practice of drawing and its reinterpretation to develop new ideas.

Brain mechanisms associated with artistic talents or skills are still not well understood. This exploratory study investigated differences in brain activity of artists and non-artists while drawing previously presented perspective line-drawings from memory and completing other drawing-related tasks. Electroencephalography (EEG) data were analyzed for power in the frequency domain by means of a Fast Fourier Transform (FFT). Low Resolution Brain Electromagnetic Tomography (LORETA) was applied to localize emerging significances. During drawing and related tasks, decreased power was seen in artists compared to non-artists mainly in upper alpha frequency ranges. Decreased alpha power is often associated with an increase in cognitive functioning and may reflect enhanced semantic memory performance and object recognition processes in artists. These assumptions are supported by the behavioral data assessed in this study and complement previous findings showing increased parietal activations in non-artists compared to artists while drawing. However, due to the exploratory nature of the analysis, additional confirmatory studies will be needed.
