Document Summary
Information that has been stored over time. Information that can be retrieved over time. Sensory input from the environment is recorded as fleeting sensory memory. Information is encoded into long-term memory for later retrieval. Immediate, initial recording of sensory information in the memory system. Example: last few words of a sentence. 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. Selective attention: mental resources are focused on only part of the stimuli around us. Exposure time for the stimulus is so small, that items cannot be rehearsed. Sperling (1960) argued that 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. Prefrontal cortex, manipulate information and tell u what to pay attention to.
