the school of psychology that emphasized the organization of perceptual
Gestalt psychology Gestalt psychology or gestaltism (German: Gestalt [ɡəˈʃtalt] "shape, form") is a philosophy of mind of the Berlin School of experimental psychology. Gestalt psychology is an attempt to understand the laws behind the ability to acquire and maintain meaningful perceptions in an apparently chaotic world. The central principle of gestalt psychology is that the mind forms a global whole with self-organizing tendencies. The assumed physiological mechanisms on which Gestalt theory rests are poorly defined and support for their existence is lacking.[1][2] The Gestalt theory of perception has been criticized as being descriptive of the end products of perception without providing much insight into the processes that lead to perception.[2] In the introduction to a 2016 special issue of the journal Vision Research on Gestalt perception, the authors concluded that "even though they study the same phenomena as earlier Gestaltists, there is little theoretical coherence. What happened to the Gestalt school that always aspired to provide a unified vision of psychology? Perhaps there is, in fact, little that holds the classic phenomena of Gestalt psychology together."[3]
Object permanence Object permanence is the understanding that objects continue to exist even when they cannot be perceived (seen, heard, touched, smelled or sensed in any way). This is a fundamental concept studied in the field of developmental psychology, the subfield of psychology that addresses the development of young children's social and mental capacities. There is not yet scientific consensus on when the understanding of object permanence emerges in human development.
