How Does Attention Determine What Is Remembered281attention is limited and when it is divided among too many tasks or the tasks are too difficult performance suffers Visual Attention in Selective and Serial282Anne Treismanstudies on attentiontheory on attention and recognition we automatically identify primitive features colour shape orientation movement etc within an environment proposed that separate systems analyze objects different visual featuresthrough parallel processing these systems all process information at the same time and we can attend selectively to one feature by effectively blocking the further processing of the others visual search taskparticipants look at a display of different objects and search for targets that differ from the other in only 1 frame looking for red dot in a group of black dots although searching for a single feature red stimulus is fast and automatic searching for 2 features is serial you need to look at the stimuli at one time and effortful takes longer and requires more attentionconjunction task stimulus you are looking for is made up of 2 simple features trying to find red Xs in a display of different coloured Xs and Ys Auditory Attention Allows Selective Hearing282because attention is limited it is hard to perform two tasks at the same time especially if they rely on the same mechanism EC Cherry described the cocktail party phenomenon you can focus on a single conversation in the midst of a chaotic cocktail party yet a particularly pertinent stimulus such as hearing your name mentioned in another conversation can capture your attention while proximity and loudness influence what you will attend to your selective attention can also determine which conversation you hear some important information gets through the filter of attention but it needs to be personally relevant information your name or it has to be particularly loud or different in some obvious physical way Selective Attention Can Operate At Multiple Stages of Processing283Donald Broadbent developed the filter theory to explain the selection nature of attention assumed that people have a limited capacity for sensory information and thus screening incoming information letting in only the most important certain sounds especially highpitched sounds are harder to ignore than others adults screams which generally signal distress such as pain or fear tend to be much higher pitched than normal speaking voices some evidence says that decisions about what to attend to are made early in the perceptual processstudies also reveal that unattended information is processed at least to some extent people are often influenced by information delivered subliminally or incidentally change blindness the fact that we are often blind to large changes in our environment because we cannot attend to everything in the vast array of visual information available to us 50 of people giving directions never noticed they were talking to a different person as long as the replacement was of the same sex and race as the first stranger change blindness shows that we can attend to a limit amount of information and that large discrepancies exist between what most people believe they see and what they actually see change blindness shows how attention influences memory sometimes it is not because we forget them ie colour of strangers shirt but more likely because we never encoded these features What Are The Basic Stages of Memory286memory allows us to take information from our experiences and store it for retrieval later however all experiences are not equally likely to be remembered psychologists view memory as information processing model that consists of 3 distinct phases encoding the processing of information so that it can be stored storage the retention of encoded representations over time that corresponds to some change in the nervous system that registers the event can last from a fraction of a second up to a lifetime retrieval the act of recalling or remembering stored information to use it
