Table 4. Mapping clusters to spectral cue fidelity. For clusters, refer to Figure 3.

Clusters	Behavioral Profile (current study)	Baumgartner Model Mapping (Baumgartner et al., 2014)	Inferred Spectral Cue Fidelity
C1 (35.29%)	Equally accurate on top/bottom and front/back identification tasks	The model predicts strong spectral-template matching + low uncertainty → sharp localization	High-fidelity cues across the full spectrum
C2 (33.33%)	Normal front–back; poor top/bottom identification tasks	Fails top/bottom tasks when corresponding spectral-template matching is unreliable	Degraded top-bottom elevation-band cues (~6–11 kHz) (Hebrank and Wright, 1974)
C3 (31.37%)	Normal top-bottom; many front–back confusions	Fails front/back when corresponding spectral-template matching is unreliable	Degraded cues for front/back distinction (likely mid/high frequencies) (Hebrank and Wright, 1974; Middlebrooks and Green, 1991)
