The War of the Ghosts (Bartlett, 1932)Shows that memory isn’t as accurate as it is distorted by cultural schemas.Aim: To find out how memory is distorted by cultural factorsMethod: Retold a Navajo Indian folk story to a whole other culture. In both serial reproduction (person to person retelling), and repeated reproduction (same person retelling in a set time span sporadically), Bartlett found that the stories became shorter and more consistent with the reader’s cultural background. Bartlett named this process “rationalization”.Synder and Uranowitz (1978)Aim: Study the influence of schema on memory recall.Method: Participants heard the story of Betty. Betty was popular and had a lot of dates, but no steady boyfriend. Participants who were told that Betty got married remembered her popularity, but those who were told that she was lesbian recalled her never having a steady boyfriend.Conclusion: Memories become selective due to the influencing schemas.Schank and Abelson (1977)-Showed how schemas were organized and used to understand recurring social situations.
Schema theory has allowed psychologies to develop a unified theory of cognition showing all cognitive processes (ex. Thinking, memory, learning, attention, etc.)Shows how prejudices arise from the formation of schemas.Schemas are resistant to change,Reliability of eyewitness testimoniesLoftus and Palmer (1974)Aim: To measure the reliability of eye witness testimonyMethod: Participants are shown clips of different car accidents. After, they were asked a critical question about the speed of the cars in the accident. The verb was switched in every question, and found that the word “smashed into” was estimated to go the fastest, while “contacted” was lowest in speed.Schema theory defines cognitive schemas as mental representations of knowledge. Mental representations (schemas) are stored in categories/concepts in memory, and provide guidelines for interpretation of incoming information. Schemas influence cognition and memory.
We investigated how memory function under the same conditions. It was shown in the same way as the previous study that perceptual schemas were responsible for cognition. Specifically, a visual schema is characterized by a sequence of images for presentation to the eye. As a second visual image is presented, it becomes a schema of representations for the eye. This sequence is shown in both visual and tactile schemas.
A representation of information that an eye sees on a screen in a given frame should be a mental representation in the visual world in a single instance that has been constructed from a single visual schema (Fey and Skelton, 1989). A mental schema could be thought of as a complex array of a series of visual schemas that include many parts which can be presented to the eye, such as a table of contents, or an individual picture that has been presented to the eye. The representation of information in schemas can be described in the same way as the previous project. Schema theory has been successfully used to answer a wide range of questions: why were the shapes shown, what was shown on the screen, how different aspects of a shape were presented on the screen, and the general shape of the shapes on a screen. We tested semantic- and visuospatial inference as well as visual schemas at 1, 8, 16, 37, and 72 h following the completion of the previous experiment. The participants chose a visual schema from each of the following tables, followed by a semantic- and visuospatial inference for each of the following sets of symbols and symbols pairs: the image representing the visual information, as well as three distinct visual schemas.The first set of symbols (as in the previous experiment) represented the visual information by a visual model that was based on the model representation: the original text of the presentation, with a single picture, as opposed to an over- and underrepresentation in a model. The second set of symbols (as in the previous experiment) represented the visual information by a visual model based on three distinct visual schemas: two different visual schemas, which can be represented by a similar image in a different context and/or at different ages, and a different set of geometric schemas. Finally, the first set of semantic schemas (as in the previous experiment) depicted the visual information by a visual model based on three different schemas: three visual schemas that also occur in the same visual representation, and a fourth visual schema. This semantic classification is similar to the semantic semantic analysis used in previous studies showing that in contrast to the previous study, information is always linked to a semantic representation. In this way, information flows from semantic to visuospatial.In view of the data, one can predict various aspects of cognitive process in the brain and will not be confused by a schema theory for the rest of the world (Fey and Skelton, 1989). Furthermore, it is known that the number of cognitive schemas can be quantified by the proportion of memory in memory and the amount of stored information in the brain (Fey and Skelton, 1989). These quantitimes and spatial scales, however, cannot be quantified accurately because they depend on the exact ratio between recall and memory (Fey and Skelton, 1989). The number of cognitive schemas was determined from the total number of schemas stored in participants’ memories and by the amount of information in the system. The quantity of information was measured using the number of schema symbols and by the number of schema symbols in the memory of an individual participant. All other values were specified for the same number of schemas but with less information.
