Object-based theories of visual attention predict that attempting to direct attention to a particular attribute of a visual object will result in an automatic selection of the whole object, including all of its features. It has been assumed, but not critically tested, that the spreading of attention from one feature to another in this manner, i.e. cross-feature attentional (CFA) effects, takes place at object-level stages of processing as opposed to early, local stages. In the present study we disambiguated these options for color-to-motion CFA by contrasting attention's effect on bivectorial transparent versus bivectorial locally paired motion displays. We found that association between features at the global, but not at the local, stage of motion processing leads to cross-feature attentional effects. These findings provide strong psychophysical evidence that such effects are indeed object-based.
