Texture Discrimination Task
The texture discrimination task is a common task used in visual perception learning. In this task, the subject must respond to the central letter task (in order to ensure that the subject remains fixated on the letter) and then identify the orientation of a target array in a peripheral A peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core compo ... location of the test stimulus. The test stimulus and mask stimulus (composed of randomly oriented V-shaped patterns) are separated by a period of time known as the stimulus-to-mask onset asynchrony. The shorter the stimulus-to-mask onset asynchrony, the more difficult the task becomes. A 2015 study has shown that action gamers typically do better than non-gamers in this task.

Perception Learning
Perceptual learning is learning better perception skills such as differentiating two musical tones from one another or categorizations of spatial and temporal patterns relevant to real-world expertise. Examples of this may include reading, seeing relations among chess pieces, and knowing whether or not an X-ray image shows a tumor. Sensory modalities may include visual, auditory, tactile, olfactory, and taste. Perceptual learning forms important foundations of complex cognitive processes (i.e., language) and interacts with other kinds of learning to produce perceptual expertise. Underlying perceptual learning are changes in the neural circuitry. The ability for perceptual learning is retained throughout life. Basic sensory discrimination Laboratory studies reported many examples of dramatic improvements in sensitivities from appropriately structured perceptual learning tasks. In visual Vernier acuity tasks, observers judge whether one line is displaced above or below a second l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orientation (vector Space)
The orientation of a real vector space or simply orientation of a vector space is the arbitrary choice of which ordered bases are "positively" oriented and which are "negatively" oriented. In the three-dimensional Euclidean space, right-handed bases are typically declared to be positively oriented, but the choice is arbitrary, as they may also be assigned a negative orientation. A vector space with an orientation selected is called an oriented vector space, while one not having an orientation selected, is called . In mathematics, '' orientability'' is a broader notion that, in two dimensions, allows one to say when a cycle goes around clockwise or counterclockwise, and in three dimensions when a figure is left-handed or right-handed. In linear algebra over the real numbers, the notion of orientation makes sense in arbitrary finite dimension, and is a kind of asymmetry that makes a reflection impossible to replicate by means of a simple displacement. Thus, in three dimensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peripheral
A peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core component of the computer. A peripheral can be categorized based on the direction in which information flows relative to the computer: * The computer receives data from an '' input device''; examples: mouse, keyboard, scanner, game controller, microphone and webcam * The computer sends data to an '' output device''; examples: monitor, printer, headphones, and speakers * The computer sends and receives data via an ''input/output device''; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter Many modern electronic devices, such as Internet-enabled digital watches, video game consoles, smartphones, and tablet computers, have in ...

Stimulus (physiology)
In physiology, a stimulus is a change in a living thing's internal or external environment. This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. Sensory receptors can receive stimuli from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system. External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold; if a signal does reach threshold, the information is transmitted to the central nervous system (CNS), where it is integrated and a decision on how to ...

Asynchrony (game Theory)
In game theory Game theory is the study of mathematical models of strategic interactions. It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. Initially, game theory addressed ..., asynchrony refers to a gameplay structure where interactions and decisions do not occur in uniformly timed rounds. Unlike synchronous systems, where agents act in coordination with a shared timing mechanism, asynchronous systems lack a global clock, allowing agents to operate at independent and arbitrary speeds relative to one another. This flexibility introduces unique strategic dynamics and complexities to the study of decision-making in such environments.Halpern, J. Y. (2003). A computer scientist looks at game theory. ''Games and Economic Behavior'', 45(1), p. 120 For example, in an asynchronous online auction, bidders may place bids at any time before the auction ends, rather than in fixed, simultaneous turns, le ...

Gamer
A gamer is someone who plays interactive games, either video games, tabletop role-playing games, skill-based card games, or any combination thereof, and who often plays for extended periods of time. Originally a hobby, gaming has evolved into a profession for some, with some gamers routinely competing in games for money, prizes, or awards. In some countries, such as the US, UK, and Australia, the term "gaming" can refer to legalized gambling, which can take both traditional and digital forms, such as through online gambling. There are many different gamer communities around the world. Since the advent of the Internet, many communities take the form of Internet forums or YouTube or Twitch virtual communities, as well as in-person social clubs. In 2021, there were an estimated 3.24 billion gamers across the globe. Etymology The term ''gamer'' originally meant ''gambler'', and has been in use since at least 1422, when the town laws of Walsall, England, referred to "any dice ...

Learning
Learning is the process of acquiring new understanding, knowledge, behaviors, skills, value (personal and cultural), values, Attitude (psychology), attitudes, and preferences. The ability to learn is possessed by humans, non-human animals, and some machine learning, machines; there is also evidence for some kind of learning in certain plants. Some learning is immediate, induced by a single event (e.g. being burned by a Heat, hot stove), but much skill and knowledge accumulate from repeated experiences. The changes induced by learning often last a lifetime, and it is hard to distinguish learned material that seems to be "lost" from that which cannot be retrieved. Human learning starts at birth (it might even start before) and continues until death as a consequence of ongoing interactions between people and their environment. The nature and processes involved in learning are studied in many established fields (including educational psychology, neuropsychology, experimental psycho ...
