In this paper, we argue that the contributions of perceivers to object perception can substantially affect what objects are represented in perceptual experience. To capture the scalar nature of these perceiver-contingent contributions, we discuss two grades of subject-dependency in object perception. The first grade, weak subject-dependency, concerns attentional changes to perceptual content like, for instance, when a perceiver is turning her head, plugging her ears, or her attention is primed for a particular cue. The second grade, strong subject-dependency, concerns generating perceptual objects whose existence depends upon their perceivers’ sensory contributions. We offer evidence from the future-directed anticipation of perceptual experts and from the feature binding of synesthetes to exemplify this nonstandard, subject-dependent form of object perception. We conclude that strongly subject-dependent perceptual objects are more than mere material objects, but are rather a necessary combination of material objects with the contributions of a perceiving subject.
