     Seeing from the heart or from the attention , that's what an interesting topic to be discussed , many argue that a person sees an object or something which is viewed by heart or feelings , but there are some people saying that there is an assessment of the object is a person attempts to commit sensation , perception and attention . The third component is basically an interaction  closely united to perform information processing on the stimulus received by a person .
     Sensory organs is something very precious in human life in which the sensory organs that humans can do easily and activities organized . But it is different when we try to make relation with someone who has the limitations of sensory organs , a small sample of people who have limitations in terms of vision , blindness is sometimes it makes it difficult to perform activities , including act and understanding the information about environment, but it is both tasks can not be denied a normal person or not is equally required to undertake the process of interpretation or assess the existing stimulus , so that the process of sensation , perception and attention is very important for every individual to perform against external environment .
      In human life  required to understand the social environment around them , so human in its development must also master of social cognition . Where social cognition is the way our minds work in understanding the environment around us in order to function adaptively in it ( ( Robert A. Baron , 2003), the point here is social cognition are all efforts made in understanding the person's social environment and make adjustments to the environment , so that people can understand the environment appropriately by doing the processing of the stimulus information received from the environment .
      Observation and understanding of the environment is something that has become a habit for human life , so that the expected human observation capable of processing the information received is accurate and true. With reference to the sensory systems that exist in the human body , in fact it is known that in the conduct of human information processing can’t be separated from the sensory system and always involve existence . After observing humans then humans would receive a stimulus that must be captured and translated appropriately . This stimulus is an object that is outside human , so with the stimulus the humans can perform a personal task is to do the task in sensation and perception .
In doing information processing , sensation is human behavior that arise as a result of stimulus or object that exists with the process of identification or detection . After the sensation then humans will follow the perception stage . By Robert L . Solso (2007 ) is the perception of high-level cognition involved in interpretation  to sensory information , so that the statement can be seen that after the initial approach that sensation then humans are required to assess or interpret the objects that have been received by involving cognition that I owned .
      Besides involving human sensation and perception to attempt to do an information processing , it is no less important is that there should be attention or concern . Attention is concentration mind in clear and vivid form , of the number of objects stimulants or group of minds ( Robert L . Solso , 2007) . Attention is therefore essential role in the interpretation of the stimulus that did exist , because humans can do with attention focusing fully on the events that are sensory or mental .
     By involving attention processing into information , humans have the great task personally . Any attention in the processing of information originated from human limitations in receiving information as a whole , because humans have the limitations in receiving stimulus thoroughly. So people just focusing the consideration at one point only. In the human attention involves a conscious and use cognition owned the interpretation of the stimuli that are beyond human .
