PSYC 100 Lecture Notes - Lecture 4: Semantic Memory, Echoic Memory, Sensory Memory
Document Summary
Encoding sensory memory: selective attention, divided attention. In retention of information deeper levels of processing result in longer lasting memory codes: structural encoding-shallow, phonemic encoding- intermediate, semantic encoding- deep. Way to enhance encoding: elaboration, dual-code theory. Iconic memory- visual sensory memory: capacity, duration, echoic memory- auditory sensory memory, capacity, duration. Zooming in on the model: from stimuli to short-term memory: some of the stimuli we encounter are picked up by our senses and processed by the sensory organs. This generates information which enters sensory memory: before this information vanishes from sensory memory, we select details to pay attention to, and send this information into working memory for rehearsal and other processing. Short-term memory: memory store in which information first has meaning, duration, capacity, limited- miller 1956, 7 +/- 2. Chunking: meaningful grouping of stimuli that can be stored as a unit in short-term memory. Working memory: functions: the short-term memory is working in many ways.
