From: Lower Attentional Skills predict increased exploratory foraging patterns
Illustration of search paths in visual (top, with the stimulus sheet overlaid – Bells test by Gauthier et al. 198930) and semantic (bottom) spaces for two participants, representative of diverse patterns of Inattentive/hyperactive behaviours, one with high (47, left, red) and the other with low (0, right, blue) rating on the ADHD-rating scale. For illustrative purposes only, we here represent the semantic space by means of the t-distributed stochastic neighbor embedding (t-SNE, tsne package in R56) algorithm for dimensionality reduction, in order to obtain a two dimensions map of the 300 dimensions vectors from the word2vec google.news model34. Insets contain the histograms for the distributions of distances.
