Attention is a central topic in psychology that is essential to partial information processing. Attention enables limited psychological resource concentrate on the most important information at the specific time. Selection of incoming sensory information can be guided by many criteria. In humans, object similarity information process is one of primary tasks of the early process. Sensory processing of visual stimuli, along with prior visual experience, leads to categorization judgments that can ultimately be used for cognition.According to some models of visual selective attention, objects in a scene activate corresponding neural representations, which compete for perceptual awareness and motor behavior. During a visual search for a target object, top-down control exerted by working memory representations of the target's defining properties resolves competition in favor of the target. People must have conceptual knowledge that would constrain which perceptual correspondences would be detected and which would be ignored. Most importantly, the similarity-based approach does not assume the existence of conceptual knowledge at the beginning of development; rather, it attempts to explain the development of this knowledge from simpler processes operating on simpler components. There are multiple correlations in the environment and that humans have perceptual and attention mechanisms capable of extracting these regularities and establishing correspondences among correlated structures. Mature representation is that inductive generalization is grounded in perceptual and attention mechanisms capable of detecting multiple correspondences or similarities. The similarity approach does not assume the existence of conceptual knowledge at the beginning of development; rather, it attempts to explain the development of this knowledge from simpler processes operating on simpler components. In particular, linguistic labels presented as count nouns are claimed to be central properties, whereas appearances are claimed to be peripheral properties. There is evidence that...
