What was Sensation , Perception , and Attention ?

Is a very important topic in psychology . Therefore in cognitive psychology will explain what it is like sensation , perception , and attention . A computational brain information processing done by the brain . As for the stages of the information processing is divided into two processes namely internal and external phenomena . Although these processes are differentiated into two but still have continuity between one process to another process . Sensation is the early detection of the stimulus . Sedangngkan perception is the interpretation of the things that our senses as we feel the aroma of cooking , taste the flavor of the dishes etc. .Detection process is a perceptual reality as determined by the sensed stimulus , sensory systems and brain structures , and prior knowledge . Our experiences in the world of perception leads us , but as well as the forces that drive the development of biological systems and kognititf .Iconic storage and echonik is a form of storage informaasi way through visual and auditory input . Is an iconic storage of information through visual input where the information we have seen memalui our senses so complete and clear but difficult to explain again the information we get . Inc shown letters and then we are in order to mention all the letters then we will find it hard to recall or mention all the letters that are shown earlier . Because iconic can only store information in one second . Unlike the echoik where we get some information through the auditory input . Inc in several different figures mentioned by every different person , then the capacity of the time we have to remember the information for four seconds . It shows that despite all the information mita know through our visual senses then we only have a second susceptible to remember it again after the information that we dapatka will disappear by itself . In contrast to our auditory senses that has vulnerable long enough to save the information that is for four seconds , when in the prone time we can not remember back then that information will go away by itself .Attention is focusing the mind , in clear and vivid nbentuk , the number of objects stimulants or group of minds . Many things that we notice every day but we have to be able to capture specific objects . For example, we were playing chess , we only pay attention to the pace of each pawn that is in use by our opponents but we do not pay attention to the other pawns pawn where every note that we do not have the potential to beat us in the game . This proves that we only pay attention to certain objects .Models of selective attention : Broadbent and Treismana. Capacity constraints and selective attention implies the existence of bottlenecks ( bottleneck ) in pemrsesan structural information . A model put the jam on , atu persiss before analiysis perceptual (model broad bent ) .b . Model treismen adalamh the idea of ​​the existence of filtration ( filter ) perceptual , which lies between the signal and the verbal analysis , which serves to filter input to selectively control the volume of messages .Automatic information processing thoroughly studied by Posner and Snyder ( 1974.1975 ) which mentions three characteristics of automatic processing :a) Automatic processing occurs without conscious intention .b ) automatic processing hidden from consciousness .c ) automated processing using fewer resources ( or even not using the resources at all )View of the cognitive neuroscience of attentiona) Efforts to find a correlation between the geographical structure of the brain and attentional processes .b ) The techniques developed in the cognitive laboratory test used as a diagnostic tool and used to hurt farmologis compounds that act affects attentional processes .Sources : Solso , Robert L et al .
