Psychophysics of numerosity comparison in humans and deep networks. Scatter plots of Numerosity, Size and Spacing coefficients for humans (A) and all deep networks (B), also showing the axes of individual features as done in41. (C) Differences between the projection on the Numerosity dimension and the projections on all individual non-numerical features for humans (left) and deep networks (right). Positive values indicate that number was a better predictor of behavior than the specific feature. Negative values would indicate that the considered feature had greater impact on discrimination choice. (D) Angles between the discrimination vector and all non-numerical features (the discrimination vector is on the y axis) for humans (left) and deep networks at two different developmental stages: Young (middle) and Mature (right).
