Conceptual priorities shape individual gaze patterns during naturalistic visual attention

Our visual landscape consists of not only people, places, and objects (e.g., “soldier”, “stadium”, “flag”), but also the conceptual relationships that unite them (e.g., “patriotism”). Because conceptual knowledge varies across individuals, this level of structure may support individualized patterns of attentional selection during naturalistic scene viewing. Here, we ask whether individuals’ gaze patterns reflect, in part, latent attentional priorities organized in conceptual space. Participants (N=61) freely explored a diverse set of immersive real-world scenes (N=100) in head-mounted VR while their gaze position was continuously recorded. We modeled gaze behavior using spatial, visual, and conceptual feature spaces, leveraging embeddings from large vision and language models, to uncover the latent priorities guiding individuals’ unique patterns of selective attention across environments. Individuals exhibited stable and idiosyncratic gaze patterns across scenes and test–retest sessions, consistent with trait-like individual differences in attention. Spatial, visual, and conceptual feature spaces each explain unique variance in individual gaze patterns, with conceptual features contributing variance beyond that explained by spatial and visual features alone. Notably, language-model–based predictions were particularly effective at capturing these individualized patterns. Together, these findings indicate that naturalistic visual attention is structured at multiple levels -- including a conceptual level -- revealing stable individual differences in how people sample and prioritize information across complex visual environments.
