perceptions

Five experiments were conducted in order to determine which of two hypotheses, initially proposed by Rock (1990), accounts for interactions between oriented elements in a visual scene. We also explored the suggestion that two hypothetical processes-namely, frame of reference and hierarchical organization- describe phenomena arising from distinct mechanisms (Spinelli, Antonucci, Daini, Martelli, & Zoccolotti, 1999). Double inducing stimulus versions of one-dimensional and two-dimensional tilt illusions, the rod-and-frame illusion, and combinations of these were used. Our data suggest that both hypotheses can predict orientation interactions in conditions in which only one mechanism-namely, the global visual mechanism of symmetry axes extraction (Wenderoth & Beh, 1977)-is activated. Which hypothesis is appropriate to predict the perceived orientation depends on some physical features of the objects.
