Document Summary
Three-stage model of memory: sensory input from the environment is recorded as fleeting sensory memory, information is processed in short-term memory, information is encoded into long-term memory for later retrieval. The immediate, initial recording of sensory information in the memory system. Major function is to hold information long enough to be processed further. Helps us to experience a constant flow of information, even if that flow is interrupted. Our brain works more like an old cartoon or stop motion. Selective attention: mental resources are focused on only part of the stimuli around us. The exposure time for the stimulus is so small, that items cannot be rehearsed. Sperling argued sensory memory capacity was larger than what was originally thought. The longer the delay the greater the memory loss. Duration of sensory memory differs for different senses. Alan baddeley(2002) proposes working memory to contain auditory, visual processing controlled by central executive, through episodic buffer.
