Evaluate schema theory with reference to research studies. Introduction Define schema Schemas are cognitive structures that organise knowledge stored in our memory. They are mental representations of categories from our knowledge, beliefs and expectations about particular aspects of the world such as people, objects, events, and situations. Expand on schema Knowledge that is stored in our memory is organized as a set of schemas or knowledge structureswhich represent the general knowledge about the world, people, events, objects, actions and situations that has been acquired from past experiences.
Schemas Imagine what it would be like if you did not have a mental model of your world. It would mean that you would not be able to How social schemas theory and related so much use of information from your past experience or to plan future actions.
Schemas are the basic building blocks of such cognitive models, and enable us to form a mental representation of the world. Wadsworth suggests that schemata the plural of schema be thought of as 'index cards' filed in the brain, each one telling an individual how to react to incoming stimuli or information.
When Piaget talked about the development of a person's mental processes, he was referring to increases in the number and complexity of the schemata that a person had learned. When a child's existing schemas are capable of explaining what it can perceive around it, it is said to be in a state of equilibrium, i.
Piaget emphasized the importance of schemas in cognitive development and described how they were developed or acquired. A schema can be defined as a set of linked mental representations of the world, which we use both to understand and to respond to situations.
The assumption is that we store these mental representations and apply them when needed. For example, a person might have a schema about buying a meal in a restaurant.
The schema is a stored form of the pattern of behavior which includes looking at a menu, ordering food, eating it and paying the bill. This is an example of a type of schema called a 'script. The schemas Piaget described tend to be simpler than this - especially those used by infants.
He described how - as a child gets older - his or her schemas become more numerous and elaborate. Piaget believed that newborn babies have a small number of innate schemas - even before they have had many opportunities to experience the world.
These neonatal schemas are the cognitive structures underlying innate reflexes.
These reflexes are genetically programmed into us. For example, babies have a sucking reflex, which is triggered by something touching the baby's lips. A baby will suck a nipple, a comforter dummyor a person's finger. Piaget, therefore, assumed that the baby has a 'sucking schema.
Shaking a rattle would be the combination of two schemas, grasping and shaking.
Assimilation and Accommodation Jean Piaget ; see also Wadsworth, viewed intellectual growth as a process of adaptation adjustment to the world. Piaget believed that cognitive development did not progress at a steady rate, but rather in leaps and bounds.
Equilibrium occurs when a child's schemas can deal with most new information through assimilation. However, an unpleasant state of disequilibrium occurs when new information cannot be fitted into existing schemas assimilation. Equilibration is the force which drives the learning process as we do not like to be frustrated and will seek to restore balance by mastering the new challenge accommodation.
Once the new information is acquired the process of assimilation with the new schema will continue until the next time we need to make an adjustment to it. Example of Assimilation A 2-year-old child sees a man who is bald on top of his head and has long frizzy hair on the sides.
Piaget's 4 Stages of Cognitive Development Piaget proposed four stages of cognitive development which reflect the increasing sophistication of children's thought: Sensorimotor stage birth to age 2 2. Pre-operational stage from age 2 to age 7 3.Schemas and Memory How schemas influence what we pay attention to and the memories we recall.

How social schemas theory and related research contributes to our understanding of the way in which people evaluate and react in their social environment Cognitive representations of social situations are referred to as 'schemas'.
Schema Theory Linguists, cognitive psychologists, and psycholinguists have used the concept of schema (plural: schemata) to understand the area of social psychology. This model attempts to explain the roles of affect and cognition in reading comprehension.
The following lesson introduces the Schema theory - its strengths and limitations. It is also a precursor to the lessons on reconstructive memory and the reliability of cognitive processes.
This lesson takes two minute periodsThe following Powerpoint was developed . Schema Theory Linguists, cognitive psychologists, and psycholinguists have used the concept of schema (plural: schemata) to understand the interaction .
