Cognitive Load
In cognitive psychology, cognitive load refers to the amount of working memory resources used. There are three types of cognitive load: ''intrinsic'' cognitive load is the effort associated with a specific topic; ''extraneous'' cognitive load refers to the way information or tasks are presented to a learner; and ''germane'' cognitive load refers to the work put into creating a permanent store of knowledge (a schema). Cognitive load theory was developed in the late 1980s out of a study of problem solving by John Sweller. Sweller argued that instructional design can be used to reduce cognitive load in learners. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load. Task-invoked pupillary response is a reliable and sensitive measurement of cognitive load that is directly related to working memory. Information may only be stored in long term memory after first being attended to, and processed by, working memory. Worki ...

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] |
Expertise Reversal Effect
The expertise reversal effect refers to the reversal of the effectiveness of instructional techniques on learners with differing levels of prior knowledge.Kalyuga, S. (2007). Expertise reversal effect and its implications for learner-tailored instruction. '' Educational Psychology Review'', 19, 509–539.Kalyuga, S., Rikers, R., Pass, F. (2012). Educational implications of expertise reversal effect in learning and performance of complex cognitive and sensorimotor skills. Educational Psychology Review, 24, 313-337. The primary recommendation that stems from the expertise reversal effect is that instructional design methods need to be adjusted as learners acquire more knowledge in a specific domain. Expertise is described as "the ability to perform fluently in a specific class of tasks." Instructional techniques that assist learners to create long term memory schema are more effective for novices or low-knowledge individuals, who approach a learning situation or task without these kn ...

Expert
An expert is somebody who has a broad and deep understanding and competence in terms of knowledge, skill and experience through practice and education in a particular field. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opin ...

Novice
A novice is a person who has entered a religious order and is under probation, before taking vows. A ''novice'' can also refer to a person (or animal e.g. racehorse) who is entering a profession with no prior experience. Religion Buddhism In many Buddhist orders, a man or woman who intends to take ordination must first become a novice, adopting part of the monastic code indicated in the vinaya and studying in preparation for full ordination. The name for this level of ordination varies from one tradition to another. In Pali, the word is samanera, which means 'small monk' or 'boy monk'. Christianity Catholicism A novice in Catholic canon law and tradition, is a ''prospective'' member of a religious order who is being tried and being proven for suitability of admission to a religious order of priests, religious brothers, or religious sisters, whether the community is one of monks or has an apostolate. After initial contact with the community, and usually a period of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Facilitation
Social facilitation is a social phenomenon in which being in the presence of others improves individual task performance. That is, people do better on tasks when they are with other people rather than when they are doing the task alone. Situations that elicit social facilitation include coaction, performing for an audience, and appears to depend on task complexity. Norman Triplett's early investigations describes social facilitation to occur during instances of coaction, which is performing a task in the presence of other people performing a similar task, while not necessarily engaging in direct interactions with each other. Triplett first observed this in cyclists, finding that cyclists rode at faster speeds when competing against other cyclists compared to when cycling alone. Social facilitation has also been known to occur when performing a task in front of an audience, or during periods of observation, sometimes referred to as audience effects. For instance, during exercise M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arousal
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and readiness to respond. Arousal is mediated by several neural systems. Wakefulness is regulated by the ARAS, which is composed of projections from five major neurotransmitter systems that originate in the brainstem and form connections extending throughout the cortex; activity within the ARAS is regulated by neurons that release the neurotransmitters acetylcholine, norepinephrine, dopamine, histamine, and serotonin. Activation of these neurons produces an increase in cortical activity and subsequently alertness. Arousal is important in regulating consciousness, attention, ...

Fundamental Attribution Error
In social psychology, fundamental attribution error (FAE), also known as correspondence bias or attribution effect, is the tendency for people to under-emphasize situational and environmental explanations for an individual's observed behavior while overemphasizing dispositional- and personality-based explanations. This effect has been described as "the tendency to believe that what people do reflects who they are", that is, to overattribute their behaviors (what they do or say) to their personality and underattribute them to the situation or context. The error is in seeing someone's actions as ''solely'' reflective of their personality rather than ''somewhat'' reflective of it and also largely prompted by circumstances. It involves a type of circular reasoning in which the answer to the question "why would they do that" is only "because they ''would'' do that." Although things like personality differences and predispositions are in fact real, the fundamental attribution error is an ...

Stereotype
In social psychology, a stereotype is a generalized belief about a particular category of people. It is an expectation that people might have about every person of a particular group. The type of expectation can vary; it can be, for example, an expectation about the group's personality, preferences, appearance or ability. Stereotypes are sometimes overgeneralized, inaccurate, and resistant to new information, but can sometimes be accurate. While such generalizations about groups of people may be useful when making quick decisions, they may be erroneous when applied to particular individuals and are among the reasons for prejudicial attitudes. Explicit stereotypes An explicit stereotype refers to stereotypes that one is aware that one holds, and is aware that one is using to judge people. If person ''A ''is making judgments about a ''particular'' person ''B'' from a group ''G'', and person ''A'' has an explicit stereotype for group ''G'', their decision bias can be partia ...

Error
An error (from the Latin ''error'', meaning "wandering") is an action which is inaccurate or incorrect. In some usages, an error is synonymous with a mistake. The etymology derives from the Latin term 'errare', meaning 'to stray'. In statistics, "error" refers to the difference between the value which has been computed and the correct value. An error could result in failure or in a deviation from the intended performance or behavior. Human behavior One reference differentiates between "error" and "mistake" as follows: In human behavior the norms or expectations for behavior or its consequences can be derived from the intention of the actor or from the expectations of other individuals or from a social grouping or from social norms. (See deviance.) Gaffes and faux pas can be labels for certain instances of this kind of error. More serious departures from social norms carry labels such as misbehavior and labels from the legal system, such as misdemeanor and crime. Departures ...

Saccade
A saccade ( , French for ''jerk'') is a quick, simultaneous movement of both eyes between two or more phases of fixation in the same direction.Cassin, B. and Solomon, S. ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company, 1990. In contrast, in smooth pursuit movements, the eyes move smoothly instead of in jumps. The phenomenon can be associated with a shift in frequency of an emitted signal or a movement of a body part or device. Controlled cortically by the frontal eye fields (FEF), or subcortically by the superior colliculus, saccades serve as a mechanism for fixation, rapid eye movement, and the fast phase of optokinetic nystagmus. The word appears to have been coined in the 1880s by French ophthalmologist Émile Javal, who used a mirror on one side of a page to observe eye movement in silent reading, and found that it involves a succession of discontinuous individual movements.

Blood Pressure
Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries. Blood pressure is usually expressed in terms of the systolic pressure (maximum pressure during one heartbeat) over diastolic pressure (minimum pressure between two heartbeats) in the cardiac cycle. It is measured in millimeters of mercury (mmHg) above the surrounding atmospheric pressure. Blood pressure is one of the vital signs—together with respiratory rate, heart rate, oxygen saturation, and body temperature—that healthcare professionals use in evaluating a patient's health. Normal resting blood pressure, in an adult is approximately systolic over diastolic, denoted as "120/80 mmHg". Globally, the average blood pressure, age standardized, has remained about the same sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Rate
Heart rate (or pulse rate) is the frequency of the heartbeat measured by the number of contractions (beats) of the heart per minute (bpm). The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide, but is also modulated by numerous factors, including, but not limited to, genetics, physical fitness, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness as well as the interaction between and among these factors. It is usually equal or close to the pulse measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. Tachycardia is a high heart rate, defined as above 100 bpm at rest. Bradycardia is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat with rates around 40–50 bpm is common and is considered normal. When the heart is not beating in a regular pattern, this is refer ...
