PSYB57-10W-W04 Representation and Knowledge in Long-Term Memory Define what knowledge is and how it leads to inferences during perception (pp. 148-151). Knowledge is often thought of as constituting particular bodies of facts, techniques, and procedures that cultures develops. We assign a perceived entity to a category, categorization allow us to draw inferences to allow us to derive information from knowledge of that group. Language requires knowledge. Discuss how a representation must be intentional and carry information (pp. 152-153). Knowledge relies on representations. - representation is a physical state that stands for an object, event or concept. It also carries information of what they stand for. Intentional Criterion: A representation must be constructed intentionally to stand for something else. - brain is designed to store information even at unconscious levels. Information-carrying criterion: A representation must carry information about what it stands for. - the ability to recall details - use these detailed memory to categorize new objects Identify the four possible formats for representations (pp. 153-166). 1. Format: the types of its code, how elements make up a representation, how these elements are arranged. Also relies on characteristics of the process that operate on them to extract information. 2. Modality Specific: Representation make use of perceptual or motor systems 3. Amodal: Representation residing outside the perceptual and motor modalities 4. Content: the information it conveys. Understand how images are modality-specific, and what neurological evidence is available to support that claim (pp. 153-160). Visual information from images are stored like photos that are captured by a digital camera. An image has three elements, which taken together determine its content: a spatiotemporal window, storage units, and stored information. 1. spatiotemporal window, scenes are captured one at a time, and are limited to an area (window). 2. storage units, can be compared with the pixels of a digital camera. 3. storage information, collective information specifies the content of the image. Pattern of brain activation on brains surface roughl depicts the shape of the stimulus. - pattern of activation forms a topographical map www.notesolution.com
