Figure 1.
Stress (left) and proportion of variance accounted for (right), plotted as a function of the dimensionality of the space, for the teddy bear (circular symbols) and butterfly (triangular symbols) categories.
Figure 2.
Two-dimensional MDS solutions for the teddy bear stimuli.
Figure 3.
Two-dimensional MDS solutions for the butterfly stimuli.
Figure 4.
Weirdness scores for the teddy bear (left) and butterfly (right) categories, plotted as a function of dimensionality of the space (weirdness scores are not possible for one-dimensional solutions).
Each symbols shows the score for one participant (i.e., one data matrix), and the three participants with the highest mean weirdness scores have been identified with labels, for demonstrative purposes.
Figure 5.
Organizational agreement curves for the teddy bear (left) and butterfly (right) categories, plotted separately for raw distances (open symbols) and ordinal rankings (closed symbols).
Plotted are the mean Pearson correlation coefficients that relate the inter-item distance vectors across dimensionalities 1–5.
Figure 6.
Prototypical agreement curves for the teddy bear (left) and butterfly (right) categories, plotted separately for raw distances (open symbols) and ordinal rankings (closed symbols).
Plotted are the mean Pearson correlation coefficients that relate the prototypicality ratings across dimensionalities 1-5.
Figure 7.
Stress (left), variance accounted for (center), and mean weirdness scores (right), plotted as a function of dimensionality.
Data are plotted separately for real data (circular symbols, solid lines), SpAM simulations (square symbols, dotted lines), and pairwise simulations (triangular symbols, dotted lines). Error bars represent ±1 standard error of the mean.
Figure 8.
Agreement curves for inter-item distance vectors (top), and prototypicality (bottom), plotted as a function of dimensionality.
Data are shown separately for the raw distance values (left) and ordinal rankings (right). Separate lines are shown for real data (circular symbols, solid lines), SpAM simulations (square symbols, dotted lines), and pairwise simulations (triangular symbols, dotted lines). Error bars represent ±1 standard error of the mean.
