Iconic (vision/images) and echoic (sound) most important aspects of our sensory memory: only a small portion is going to get through to short-term memory; largely depended on certain triggers. > habituated or desensitized stimuli forgotten within seconds. Foreground information able to go on to further processing. Internal trigger motivated and aroused to perceive certain information: arousal -> stimuli, external trigger selective attention to changes in environment, stimuli -> arousal. Registered and transferred to short-term memory: short-term memory ( working memory ): brief storage of information currently being used/limited capacity, duration: less than twenty seconds, it manipulates the information, processing and filtering the information.
