Characteristics of participants in the Blind_NH and Blind_HH groups.

Infits and targeting of the DS-SLQ.
(A) Histogram showing the distribution of item and person infit statistics. Most items and persons have infit values between 0.5 and 1.5, indicated by the red dash lines. (B) Comparison of the range of person measures (upper panel) and item measures (lower panel) on the same logit scale.
Fig 2.
Perceived sound localization abilities across hearing and vision status.
(A) Comparison of hearing person measures from the DS-SLQ between blind individuals with normal hearing (Blind_NH) and those with hearing loss (Blind_HH). (B) Scatter plot illustrating the relationship between perceived sound localization abilities and onset of blindness in blind individuals. (C) Relationship between perceived sound localization ability and onset of hearing loss in blind individuals. In each plot, orange and cyan colors represent Blind_NH and Blind_HH groups, respectively. Regression lines are provided in the scatter plots.
Fig 3.
Echolocation and perceived sound localization abilities in blind individual.
(A) Proportion of echolocators among Blind_NH and Blind_HH participants. (B) Scatter plot showing the correlation between perceived sound localization abilities and echolocation rating. Regression lines are also provided in the scatter plot. In both plots, the orange and cyan colors represent Blind_NH and Blind_HH groups, respectively.
Fig 4.
Comparison of perceived sound and visual localization abilities in blind participants. The scatterplot shows a relationship between perceived sound localization abilities and perceived vision localization abilities (both in logits). The diagonal line represents the equality line, where equal perceived localization abilities in both modalities would lie. Orange circles represent Blind_NH and cyan triangles represent Blind_HH.
