Object-base; In general, object-based indicates that something such as a theory, language, or model is based on the concept of object.
Object based attention refers to the relationship between an ‘object’ representation and a person’s visually-stimulated, selective attention,
as opposed to a relationship involving either a spatial or a feature representation; although these types of selective attention are not necessarily mutually exclusive.
Research into object-based attention suggests that attention improves the quality of the sensory representation of a selected object, and results in the enhanced processing of that object’s features.
The concept of an ‘object’, apropos object-based attention, entails more than a physical thing that can be seen and touched.
It includes a perceptual unit or group, namely, elements in a visual field (stimuli) organised coherently by Gestalt factors such as collinearity, closure, and symmetry.
