Subclaims¶

q3 i? Memory of uncertainty values was higher with stop light colors and with both visualizations than without any uncertainty visualization. → Glaser 2022

Results table of the mixed ANOVA on memory of uncertainty values lists significant post-hoc comparisons with 95% confidence intervals: "Stop light colors > without" and "Both > without". No standardized effect size is printed for this comparison.

Discussion¶

Related Claims¶

• Uncertainty values of more certain elements and their verbal scientific justifications were remembered better than those of uncertain elements — related
• For uncertain architectural elements, geometric contrast yielded worse memory of appearance than no visualization, stop light colors, or both visualizations — related
• For certain architectural elements, geometric contrast yielded better memory of appearance than stop light colors — related
• Adding relevant pictures or graphics to text improves learning from it, with a small pooled effect on reading comprehension, though whether dual coding explains the benefit is disputed — a broader claim this one bears on
