Discrimination Learning
Discrimination learning is defined in psychology as the ability to respond differently to different stimuli. This type of learning is used in studies regarding operant and classical conditioning. Operant conditioning involves the modification of a behavior by means of reinforcement or punishment. In this way, a discriminative stimulus will act as an indicator to when a behavior will persist and when it will not. Classical conditioning involves learning through association when two stimuli are paired together repeatedly. This conditioning demonstrates discrimination through specific micro-instances of reinforcement and non-reinforcement. This phenomenon is considered to be more advanced than learning styles such as generalization and yet simultaneously acts as a basic unit to learning as a whole. The complex and fundamental nature of discrimination learning allows for psychologists and researchers to perform more in-depth research that supports psychological advancements. Research on ...

Classical Conditioning
Classical conditioning (also known as Pavlovian or respondent conditioning) is a behavioral procedure in which a biologically potent stimulus (e.g. food) is paired with a previously neutral stimulus (e.g. a triangle). It also refers to the learning process that results from this pairing, through which the neutral stimulus comes to elicit a response (e.g. salivation) that is usually similar to the one elicited by the potent stimulus. Classical conditioning is distinct from operant conditioning (also called instrumental conditioning), through which the strength of a voluntary behavior is modified by reinforcement or punishment. However, classical conditioning can affect operant conditioning in various ways; notably, classically conditioned stimuli may serve to reinforce operant responses. Classical conditioning was first studied in detail by Ivan Pavlov, who conducted experiments with dogs and published his findings in 1897. During the Russian physiologist's study of digestion, Pav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blocking Effect
In Kamin's blocking effect the conditioning of an association between two stimuli, a conditioned stimulus (CS) and an unconditioned stimulus (US) is impaired if, during the conditioning process, the CS is presented together with a second CS that has already been associated with the unconditioned stimulus. For example, an agent (such as a mouse in the figure) is exposed to a light (the first conditioned stimulus, CS1), together with food (the unconditioned stimulus, US). After repeated pairings of CS1 and US, the agent salivates when the light comes on (conditioned response, CR). Then, there are more conditioning trials, this time with the light (CS1) and a tone (CS2) together with the US. Now, when tested, the agent does not salivate to the tone (CS2). In other words, an association between the tone CS2 and the US has been "blocked" because the CS1–US association already exists. This effect was most famously explained by the Rescorla–Wagner model. The model says, essentia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pattern Recognition (psychology)
In psychology and cognitive neuroscience, pattern recognition describes a cognitive process that matches information from a stimulus with information retrieved from memory.Eysenck, Michael W.; Keane, Mark T. (2003). Cognitive Psychology: A Student's Handbook (4th ed.). Hove; Philadelphia; New York: Taylor & Francis. . OCLC 894210185. Retrieved 27 November 2014. Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory. An early example of this is learning the alphabet in order. When a carer repeats ‘A, B, C’ multiple times to a child, utilizing the pattern recognition, the child says ‘C’ after they hear ‘A, B’ in order. Recognizing patterns allows us to predict and expect what is coming. The process of pattern recognition involves matching the information received with the information already stored in the brain.

Mathematical Psychology
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance). The mathematical approach is used with the goal of deriving hypotheses that are more exact and thus yield stricter empirical validations. There are five major research areas in mathematical psychology: learning and memory, perception and psychophysics, choice and decision-making, language and thinking, and measurement and scaling. Although psychology, as an independent subject of science, is a more recent discipline than physics, the application of mathematics to psychology has been done in the hope of emulating the success of this approach in the physical sciences, which dates back to at least the seventeenth century. Mathematics in psychology is used e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-cultural Psychology
Cross-cultural psychology is the scientific study of human behavior and mental processes, including both their variability and invariance, under diverse cultural conditions. Through expanding research methodologies to recognize cultural variance in behavior, language, and meaning it seeks to extend and develop psychology.Gielen, U. P., & Roopnarine, J. L. (Eds.). (2016). ''Childhood and adolescence: Cross-cultural perspectives and applications'' (2nd ed.). Santa Barbara, CA: Praeger. Since psychology as an academic discipline was developed largely in North America and Europe, some psychologists became concerned that constructs and phenomena accepted as universal were not as invariant as previously assumed, especially since many attempts to replicate notable experiments in other cultures had varying success.Smith, Peter B., Fischer, R., Vignoles, V. L. & Bond, M. H. (Eds.). (2013). ''Understanding Social Psychology Across Cultures: Engaging with others in a changing world'' (2nd ed.) ...

Developmental Psychology
Developmental psychology is the science, scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, morality, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation. Developmental psychology examines the influences of nature ''and'' nurture on the process of human development, as well as processes of change in context across time. Many researchers are interested in the inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Analysis Of Behaviour
The experimental analysis of behavior is school of thought in psychology founded on B. F. Skinner's philosophy of radical behaviorism and defines the basic principles used in applied behavior analysis. A central principle was the inductive reasoning data-driven examination of functional relations, as opposed to the kinds of hypothetico-deductive learning theory that had grown up in the comparative psychology of the 1920–1950 period. Skinner's approach was characterized by observation of measurable behavior which could be predicted and controlled. It owed its early success to the effectiveness of Skinner's procedures of operant conditioning, both in the laboratory and in behavior therapy. Basic learning processes in behavior analysis Classical (or respondent) conditioning In classical or respondent conditioning, a neutral stimulus (''conditioned stimulus'') is delivered just before a reflex-eliciting stimulus (''unconditioned stimulus'') such as food or pain.

Cognitive Psychology
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s in a break from behaviorism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. The domain of cognitive psychology overlaps with that of cognitive science, which takes a more interdisciplinary approach and includes studies of non-human subjects and artificial intelligence. History Philosophically, ruminations on the human mind and its processes have been around since the times of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparative Psychology
Comparative psychology refers to the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history, adaptive significance, and development of behavior. Research in this area addresses many different issues, uses many different methods and explores the behavior of many different species from insects to primates. Comparative psychology is sometimes assumed to emphasize cross-species comparisons, including those between humans and animals. However, some researchers feel that direct comparisons should not be the sole focus of comparative psychology and that intense focus on a single organism to understand its behavior is just as desirable; if not more so. Donald Dewsbury reviewed the works of several psychologists and their definitions and concluded that the object of comparative psychology is to establish principles of generality focusing on both proximate and ultimate causation.Dewsbury, D. (1984). ''Comparative Psy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychology Of Learning
The psychology of learning is a theoretical science that covers the various psychological theories that relate with learning. Throughout history, there has been many various psychological learning theories. Some take on a more behaviorist approach which focuses on inputs and reinforcements. Other approaches, such as theories related to neuroscience and social cognition, focus more on the brain's organization and structure to define learning. Some psychological approaches, such as social constructivism, focus more on one's interaction with the environment and with others. Other theories, such as those related to motivation, like the growth mindset, focus more on the individual. Psychology of learning is also very applicable today. There has been extensive research in recent years that looks closely at how students are learning both inside and outside the classroom. This information is then used to present new and more cooperative approaches to homework, tests and the student's abil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operant Conditioning
Operant conditioning, also called instrumental conditioning, is a learning process where behaviors are modified through the association of stimuli with reinforcement or punishment. In it, operants—behaviors that affect one's environment—are conditioned to occur or not occur depending on the environmental consequences of the behavior. Operant conditioning originated in the work of Edward Thorndike, whose law of effect theorised that behaviors arise as a result of whether their consequences are satisfying or discomforting. In the 20th century, operant conditioning was studied by behaviorist psychologists, who believed that much, if not all, of mind and behaviour can be explained as a result of envirionmental conditioning. Reinforcements are environmental stimuli that increase behaviors, whereas punishments are stimuli that decrease behaviors. Both kinds of stimuli can be further categorised into positive and negative stimuli, which respectively involve the addition or removal o ...
