Statistical relationships between objects in scenes are used to optimize perceptual processing of a scene. Specifically, previous studies have shown that semantic features of objects and scenes are used to guide eye movements and improve visual search. The expected size of the object relative to the scene (i.e. canonical size of a pot in a kitchen) is known as object-scene scale consistency and is one feature that may impact scene processing. To that end, we aim to investigate behavioral responses to variations in object-scene scale consistency within real-world indoor scenes. Participants will briefly view a real-world object against a neutral background that is then replaced with a scene. The categorical size of the object and the zoom level of the scene (i.e. zoomed in, zoomed out) are used in conjunction to make objects seem mis-scaled or canonically scaled with the scene. Participants then view a second scene that is either of the same or different semantic category as the first. The task is to respond if the two scenes are categorically congruent. The chosen task is deliberately orthogonal to the prior object-scene size scaling to assess if mis-scaling impairs ability to compare scenes categorically. The design is such that categorical object size, object-scene size congruency, and object semantic congruence with the first scene is counterbalanced. Importantly, scene zoom level is not indicative of object-scene size scaling. We predict that if the object is semantically and/or size incongruent to the scene, that an impediment to performance (RT, accuracy) will be observed. Measuring behavior in this task will begin to clarify how object-scene size information is incorporated into scene and object processing more generally. Based on previous neuroimaging work the transverse occipital sulcus (TOS) has shown neural selectivity to object-size relationships. Future steps include translating this behavioral paradigm into a TMS experiment to further investigate the neural mechanism behind object-scene scaling and semantics. |
