A schema (pl. schemata), in psychology and cognitive science, is a mental structure that represents some aspect of the world. Schemata were initially introduced into psychology and education through the work of the British psychologist Sir Frederic Bartlett (1886–1969)[[Bartlett, 1932]]. This learning theory views organized knowledge as an elaborate network of abstract mental structures which represent one's understanding of the world. Schema theory was developed by the educational psychologist R. C. Anderson. The term schema was used by Jean Piaget in 1926, so it was not an entirely new concept. Anderson, however, expanded the meaning.
People use schemata to organize current knowledge and provide a framework for future understanding. Examples of schemata include Rubric (academic), stereotypes, social roles, scripts, worldviews, and archetypes. In Piaget's theory of development, children adopt a series of schemata to understand the world.
Schemata are an effective tool for understanding the world. Through the use of schemata, most everyday situations do not require effortful thought— automatic thought is all that is required.
People can quickly organize new perceptions into schemata and act effectively without effort. For example, most people have a stairway schema and can apply it to climb staircases they've never seen before.
However, schemata can influence and hamper the uptake of new information (proactive interference), such as when existing stereotypes, giving rise to limited or biased discourses and expectations (prejudices), may lead an individual to 'see' or 'remember' something that has not happened because it is more believable in terms of his/her schema. For example, if a well-dressed businessman draws a knife on a vagrant, the schemata of onlookers may (and often do) lead them to 'remember' the vagrant pulling the knife. Such distortion of memory has been demonstrated. (See Background research below.)
Schemata are interrelated and multiple conflicting schemata can be applied to the same information. Schemata are generally thought to have a level of activation, which can spread among related schemata. Which schema is selected can depend on factors such as current activation, accessibility, and priming.
Accessibility is how easily a schema comes to mind, and is determined by personal experience and expertise. This can be used as a cognitive shortcut; it allows the most common explanation to be chosen for new information.
With priming, a brief imperceptible stimulus temporarily provides enough activation to a schema so that it is used for subsequent ambiguous information. Although this may suggest the possibility of subliminal messages, the effect of priming is so fleeting that it is difficult to detect outside laboratory conditions. Furthermore, the mere exposure effect —which requires consciousness of the stimuli— is far more effective than priming.
Sufferers of Korsakov's syndrome are unable to form new memories, and must approach every situation as if they had just seen it for the first time. Many sufferers adapt by continually forcing their world into barely-applicable schemata, often to the point of incoherence and self-contradiction.[citation needed]
The original concept of schemata is linked with that of reconstructive memory as proposed and demonstrated in a series of experiments by Bartlett (1932). By presenting participants with information that was unfamiliar to their cultural backgrounds and expectations and then monitoring how they recalled these different items of information (stories, etc.), Bartlett was able to establish that individuals' existing schemata and stereotypes influence not only how they interpret 'schema-foreign' new information but also how they recall the information over time. One of his most famous investigations involved asking participants to read a Native American folk tale, "The War of the Ghosts," and recall it several times up to a year later. All the participants transformed the details of the story in such a way that it reflected their cultural norms and expectations, i.e. in line with their schemata. The factors that influenced their recall were:
Omission of information that was considered irrelevant to a participant;
Transformation of some of the detail, or of the order in which events etc were recalled; a shift of focus and emphasis in terms of what was considered the most important aspects of the tale;
Rationalisation: details and aspects of the tale that would not make sense would be 'padded out' and explained in an attempt to render them comprehensible to the individual in question;
Cultural shifts: The content and the style of the story were altered in order to appear more coherent and appropriate in terms of the cultural background of the participant.
Bartlett's work was crucially important in demonstrating that long-term memories are neither fixed nor immutable but are constantly being adjusted as our schemata evolve with experience. In a sense it supports the existentialist view that we construct our past and present in a constant process of narrative/discursive adjustment, and that much of what we 'remember' is actually confabulated (adjusted and rationalised) narrative that allows us to think of our past as a continuous and coherent string of events, even though it is probable that large sections of our memory (both episodic and semantic) are irretrievable to our conscious memory at any given time.
Further work on the concept of schemata was conducted by Brewer and Treyens (1981) who demonstrated that the schema-driven expectation of the presence of an object was sometimes sufficient to trigger its erroneous recollection. An experiment was conducted where participants were requested to wait in a room identified as an academic's study and were later asked about the room's contents. A number of the participants recalled having seen books in the study whereas none were present. Brewer and Treyens concluded that the participants' expectations that books are present in academics' studies were enough to prevent their accurate recollection of the scenes.
New information that falls within an individual's schema is easily remembered and incorporated into their worldview. However, when new information is perceived that does not fit a schema, many things can happen. The most common reaction is to simply ignore or quickly forget the new information.[citation needed] This can happen on a deep level—frequently an individual does not become conscious of or even perceive the new information.
However, when the new information cannot be ignored, existing schemata must be changed.
Assimilation is the reuse of schemata to fit the new information. For example, when an unfamiliar dog is seen, a person will probably just assimilate it into their dog schema. However, if the dog behaves strangely, and in ways that don't seem dog-like, there will be accommodation as a new schema is formed for that particular dog.
Definition: A cognitive framework or concept that helps organize and interpret information. Schemas can be useful, because they allow us to take shortcuts in interpreting a vast amount of information. However, these mental frameworks also cause us to exclude pertinent information in favor of information that confirms our pre-existing beliefs and ideas. Schemas can contribute to stereotypes and make it difficult to retain new information that does not conform to our established schemas.
The way that human beings make sense of our world is by creating knowledge structures called schemas. A schema is a bundle of knowledge that tells you what to expect in a situation and why it is happening. For example, going to a party at a friend's house could be a buzzing confusion of people if you did not have knowledge about what to expect and how to act. Because of your knowledge about parties, though, you may expect loud conversation, music, dancing, or drinks. You know that you should find the hosts and let them know you are there. You might not ordinarily throw a coat on someone's bed, but if they are having a big party, that is an acceptable place to pile coats. All of this knowledge helps you get around the world.
An important way that we form these schemas is by telling stories and repeating them. Anyone who has spent a lot of time with a preschooler knows that they ask you the same questions over and over. They want repetition of stories. They are using this information to help them figure out how the world works. For a 4- or 5-year-old, almost everything in the world is new.
As adults, when something strange, new, wonderful, or traumatic happens, we return to that preschool behavior. Think first about a traumatic situation. Following the terrorist attacks of 9/11, the attacks on the World Trade Center and the Pentagon were all that anyone could talk about. They talked about where they were, and what they were doing. They followed the news reports to find out what happened and why. All of this was done to try to create some bundle of knowledge that would help this unthinkable tragedy make sense.
A schema is a cognitive structure of knowledge we have in our minds.
Without them, we’d probably go insane. They affect our lifes in every way. They can be at the root of racism, they can be used by some to indoctrinate others into desctructive cults.
Yet they’re perfectly natural, unavoidable and part of what makes us who we are.
Understand this process can help us with our daily interactions whether it be personally or professionally.
While individuals may have a spoken and even perhaps belief that they seek to "Deny Ignorance" they may in fact work against themselves. As the mind will even subconscious seek to reinforce existing beliefs.

Through schema logic, 10 people witness a monkey on a leash, dancing to music played by a man in an orange & green vest on the corner of Broad & High at 12:00 on a Friday as commuters rush past. How many of those ten people will report the exact sequence, details and observations? My guess is, 10 different descriptions with varying levels of detail and/or omission of certain points.
I have a BSc. Honours Degree in Psychology from the Open University and am a Graduate Member of the British Psychological Society. I was always fascinated by Psychology, long before I completed my degree. Understanding what can motivate people and how this can affect behaviour definitely helps makes my everyday interactions much more successful.

Hello. Unfortunately I am not sure if I can it's a rather involved if not intergal bit of information. I promise you you won't be disapointed if you read it. Although the online course offered not far above this one may help.

Not really. Schema is not really good or bad but it IS a two edged sword more of a shortcut we all use really. Thought using Schemata highlights that.
