Zenon Pylyshyn
Zenon Walter Pylyshyn (; 25 August 1937 – 6 December 2022) was a Canadian cognitive scientist and philosopher. He was a Canada Council Senior Fellow from 1963 to 1964. Pylyshyn's research generally involved the theoretical analysis of the nature of the human cognitive systems behind perception, imagination, and reasoning. He developed visual indexing theory (sometimes called the FINST theory) which hypothesizes a pre-conceptual mechanism responsible for individuating, tracking, and directly (or demonstratively) referring to the visual objects that could be interrogated by cognitive processes. His very influential multiple object tracking experiment methodology emerged from this work. Early life and education Pylyshyn was born in Montreal, Quebec, Canada, to Ukrainian immigrants Anna and Yuriy. He obtained a degree in Engineering Physics (BEng 1959) from McGill University and in control systems (MSc 1960) and experimental psychology (PhD 1963), both from the Regina Campus, ...

20th-century Philosophy
Contemporary philosophy is the present period in the history of Western philosophy beginning at the early 20th century with the increasing professionalization of the discipline and the rise of Analytic philosophy, analytic and continental philosophy. The phrase "contemporary philosophy" is a piece of technical terminology in philosophy that refers to a specific period in the history of Western philosophy (namely the philosophy of the 20th and 21st centuries). However, the phrase is often confused with modern philosophy (which refers to an earlier period in Western philosophy), postmodern philosophy (which refers to some philosophers' criticisms of modern philosophy), and with a non-technical use of the phrase referring to any recent philosophic work. Professionalization Process Professionalization is the social process by which any trade or occupation establishes the group Norm (sociology), norms of conduct, acceptable wikt:qualification, qualifications for membership of the pro ...

Visual Indexing Theory
Visual indexing theory, also known as FINST theory, is a theory of early visual perception developed by Zenon Pylyshyn in the 1980s. It proposes a pre-attentive mechanism (a ‘FINST’) whose function is to individuate salient elements of a visual scene, and track their locations across space and time. Developed in response to what Pylyshyn viewed as limitations of prominent theories of visual perception at the time, visual indexing theory is supported by several lines of empirical evidence. Overview Fingers of instantiation 'FINST' abbreviates ‘FINgers of INSTantiation’. Pylyshyn describes visual indexing theory in terms of this analogy.Pylyshyn, Z.W. (1989). The role of location indexes in spatial perception: a sketch of the FINST spatial index model. Cognition, 32, 65–97. Imagine, he proposes, placing your fingers on five separate objects in a scene. As those objects move about, your fingers stay in respective contact with each of them, allowing you to continually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The main campus is located on of land, surrounded by residential neighbourhoods and the Thames River (Ontario), Thames River bisecting the campus's eastern portion. The university operates twelve academic faculties and schools. The university was founded on 7 March 1878 by Bishop Isaac Hellmuth of the Diocese of Huron, Anglican Diocese of Huron as The Western University of London, Ontario. It incorporated Huron University College, Huron College, which had been founded in 1863. The first four faculties were Arts, Divinity, Law and Medicine. The university became non-denominational in 1908. Beginning in 1919, the university had affiliated with several denominational colleges. The university grew substantially in the Post-war, post-World War II era, and a number of faculties and schools were added. Western is a co-educational univer ...

Computer Science
Computer science is the study of computation, information, and automation. Computer science spans Theoretical computer science, theoretical disciplines (such as algorithms, theory of computation, and information theory) to Applied science, applied disciplines (including the design and implementation of Computer architecture, hardware and Software engineering, software). Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of re ...

Psychology
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both consciousness, conscious and Unconscious mind, unconscious phenomena, and mental processes such as thoughts, feelings, and motivation, motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Biological psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as Behavioural sciences, behavioral or Cognitive science, cognitive scientists. Some psychologists attempt to understand the role of mental functions in i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-term Memory
Short-term memory (or "primary" or "active memory") is the capacity for holding a small amount of information in an active, readily available state for a short interval. For example, short-term memory holds a phone number that has just been recited. The duration of short-term memory (absent rehearsal or active maintenance) is estimated to be on the order of seconds. The commonly cited capacity of 7 items, found in Miller's Law, has been superseded by 4±1 items. In contrast, long-term memory holds information indefinitely. Short-term memory is not the same as working memory, which refers to structures and processes used for temporarily storing and manipulating information. Stores The idea of separate memories for short-term and long-term storage originated in the 19th century. A model of memory developed in the 1960s assumed that all memories are formed in one store and transfer to other stores after a small period of time. This model is referred to as the "modal model", mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Control Systems
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling Process (engineering), processes or machines. The control systems are designed via control engineering process. For continuously modulated control, a feedback controller is used to automatically control a process or operation. The control system compares the value or status of the process variable (PV) being controlled with the desired value or Setpoint (control system), setpoint (SP), and applies the difference as a control signal to bring the process variable output of the Plant (control theory), plant to the same value as the setpoint. For Sequential logic, sequential and combinational logic, software logic, such as in a programmable logic controller, is used. Open-loop and closed-loop co ...
