• Developmental multisensory integration and social perception in infancy reveals how early cross-modal cues—from faces and gaze to tactile interactions—shape recognition and joint visual attention, with cross-species developmental interference affecting learning [15], [9], [11], [7].

• Perceptual adaptation, transformation of the visual field, and temporal processing: the visual system recalibrates under prism-like displacements and disparity changes, with multiple studies documenting adaptation processes and their time course [4], [5], [13], [16], [17].

• Color-luminance interactions and texture-based organization: chromatic and luminance cues jointly constrain perceptual structure, with equivalent luminance contrast and double opponency shaping texture segregation [1], [6].

• Cross-modal sensory coupling in social and somatosensory contexts: tactile-somatosensory inputs modulate social interaction and learning, including still-face/touch paradigms and sensory recombination techniques [2], [3], [14].
