Cognitive Load Theory
In cognitive psychology, cognitive load is the effort being used in the working memory. According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: * ''Intrinsic'' cognitive load is the effort associated with a specific topic. * ''Germane cognitive load refers to the work put into creating a permanent store of knowledge (a schema).'' * ''Extraneous'' cognitive load refers to the way information or tasks are presented to a learner. However, over the years, the additivity of these types of cognitive load has been investigated and questioned. Now it is believed that they circularly influence each other. 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Psychology
Cognitive psychology is the scientific study of human 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. History Philosophically, ruminations on the human mind and its processes have been around since the times of the Ancient Greece, ancient Greeks. In 387 BCE, Plato had suggested that the brain was the seat of the mental processes. In 1637, René Descartes posited that humans are born with innate ideas and ...

Worked-example Effect
The worked-example effect is a learning effect predicted by cognitive load theory. Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving and discovery learning. According to Sweller: "The worked example effect is the best known and most widely studied of the cognitive load effects". Worked examples improve learning by reducing cognitive load during skill acquisition, and "is one of the earliest and probably the best known cognitive load reducing technique". In particular, worked examples provide instructions to reduce extraneous cognitive load and increase germane cognitive load for the learner initially when few schemas are available. Intrinsic cognitive load is a third type of cognitive load that provides a base load that is irreducible. Extraneous load is reduced by scaffolding of worked examples at the beginning of skill acquisition. Finally, worked exa ... [...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 physiology, physiological and psychology, psychological state of being awoken or of Five senses, sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the human brain, 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 reactivity. 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 Cerebral cortex, cortex; activity within the ARAS is regulated by neurons that release the neurotransmitters norepinephrine, acetylcholine, dopamine, serotonin and histamine. Activation of these neurons produces an increase in cortical activity and subsequently alertness. Arousal is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fundamental Attribution Error
In social psychology, the fundamental attribution error is a cognitive attribution bias in which observers underemphasize situational and environmental factors for the behavior of an actor while overemphasizing dispositional or personality factors. In other words, observers tend to overattribute the behaviors of others to their personality (e.g., ''he is late because he's selfish'') and underattribute them to the situation or context (e.g., ''he is late because he got stuck in traffic''). Although personality traits and predispositions are considered to be observable facts in psychology, the fundamental attribution error is an error because it misinterprets their effects. The group attribution error is identical to the fundamental attribution error, where the bias is shown between members of different groups rather than different individuals. The ultimate attribution error is a derivative of the fundamental attribution error and group attribution error relating to the acti ...

Implicit Stereotype
An implicit bias or implicit stereotype is the pre-reflective attribution of particular qualities by an individual to a member of some social out group. Implicit stereotypes are thought to be shaped by experience and based on learned associations between particular qualities and social categories, including race and/or gender. Individuals' perceptions and behaviors can be influenced by the implicit stereotypes they hold, even if they are ''sometimes'' unaware they hold such stereotypes. Implicit bias is an aspect of implicit social cognition: the phenomenon that perceptions, attitudes, and stereotypes can operate prior to conscious intention or endorsement. The existence of implicit bias is supported by a variety of scientific articles in psychological literature. Implicit stereotype was first defined by psychologists Mahzarin Banaji and Anthony Greenwald in 1995. Implicit stereotypes - unconscious associations held by individuals - can influence behavior even when they contra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schema (psychology)
In psychology and cognitive science, a schema (: schemata or schemas) describes a pattern of thought or behavior that organizes categories of information and the relationships among them. It can also be described as a mental structure of preconceived ideas, a framework representing some aspect of the world, or a system of organizing and perceiving new information, such as a mental schema or conceptual model. Schemata influence attention and the absorption of new knowledge: people are more likely to notice things that fit into their schema, while re-interpreting contradictions to the schema as exceptions or distorting them to fit. Schemata have a tendency to remain unchanged, even in the face of contradictory information. Schemata can help in understanding the world and the rapidly changing environment. People can organize new perceptions into schemata quickly as most situations do not require complex thought when using schema, since automatic thought is all that is required. ...

Subconscious
In psychology, the subconscious is the part of the mind that is not currently of focal awareness. The term was already popularized in the early 20th century in areas ranging from psychology, religion and spirituality. The concept was heavily popularized by Joseph Murphy's 1963 self-help book ''The Power of Your Subconscious Mind''. Scholarly use of the term The word ''subconscious'' represents an anglicized version of the French ''subconscient'' as coined by John Norris, in "An Essay Towards the Theory of the Ideal or Intelligible World” (1708): "The immediate objects of Sense, are not the objects of Intellection, they being of a Subconscient ubconsciousnature." A more recent use was in 1889 by the psychologist Pierre Janet (1859–1947), in his doctorate of letters thesis, ''Of Psychological Automatism'' (. Janet argued that underneath the layers of critical-thought functions of the conscious mind lay a powerful awareness that he called the subconscious mind.Henri F. Ellenb ...

Stereotype
In social psychology, a stereotype is a generalization, 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 make information processing easier by allowing the perceiver to rely on previously stored knowledge in place of incoming information. Stereotypes are often faulty generalization, faulty, inaccurate, and Belief perseverance, resistant to new information. Although stereotypes generally have negative implications, they aren't necessarily negative. They may be positive, neutral, or negative. They can be broken down into two categories: explicit stereotypes, which are conscious, and implicit stereotypes, which are subconscious. Explicit stereotypes An explicit stereotype is a belief about a group that a person is consciously aware of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Error
An error (from the Latin , meaning 'to wander'Oxford English Dictionary, s.v. “error (n.), Etymology,” September 2023, .) is an inaccurate or incorrect action, thought, or judgement. 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 (statistics), 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 (sociology), 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 f ...

Blood Pressure
Blood pressure (BP) is the pressure of Circulatory system, 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 a brachial artery, where it is most commonly measured. Blood pressure is usually expressed in terms of the systolic pressure (maximum pressure during one Cardiac cycle, heartbeat) over diastolic pressure (minimum pressure between two heartbeats) in the cardiac cycle. It is measured in Millimetre of mercury, millimetres of mercury (mmHg) above the surrounding atmospheric pressure, or in Pascal (unit), kilopascals (kPa). The difference between the systolic and diastolic pressures is known as pulse pressure, while the average pressure during a cardiac cycle is known as mean arterial pressure. Blood pressure is one of the vital signs—together with respiratory rate, heart rate, Oxygen saturation (me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Rate
Heart rate is the frequency of the cardiac cycle, heartbeat measured by the number of contractions of the heart per minute (''beats per minute'', or bpm). The heart rate varies according to the body's Human body, physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics, physical fitness, Psychological stress, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness, as well as the interaction between these factors. It is usually equal or close to the pulse rate measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 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 ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
