Figure 4. Bar-chart of reciprocal penalised path accuracy (pPA) by Age-Group and Sex.

Reciprocal pPA is a unitless measure of spatial accuracy whilst tracing, adjusted to standardise for individual variation in speed. Statistically significant differences between Age-Groups and Sex were found on this outcome (both p<.001), with no significant interaction between them. Performance improved with increasing age and was consistently better (higher) in Females. Note: Error bars represent 95% confidence intervals.
