Abstract

Humans and other animals perceive with many different sensory modalities, includ- ing olfaction, touch, audition, vision, echolocation, proprioception, gustation, and some other senses, depending on different criteria and definitions. Given its broad range, it is not possible to give a comprehensive overview of all of the philosophi- cal, psychological, and neuroscientific studies about perception in one chapter, so what will be offered here is quite selective. In the introduction, we will discuss basic concepts such as figure-ground segregation and scene analysis. Section 1.1 provides a historical overview of psychological theories of perception since the late 19th century. Section 1.2 discusses the information-processing approach and hierarchical explanations, while section 1.3 looks into the historical development of philosophical studies of perception. Sections 2.1–2.3 introduce contemporary issues, and 3.1–3.3 provide future directions.
