  2. Bottom–up and top–down design - Wikipedia

    en.wikipedia.org/wiki/Bottom–up_and_topdown...

    An example of top-down processing: Even though the second letter in each word is ambiguous, top–down processing allows for easy disambiguation based on the context. These terms are also employed in cognitive sciences including neuroscience, cognitive neuroscience and cognitive psychology to discuss the flow of information in processing. [6]

  3. Context effect - Wikipedia

    en.wikipedia.org/wiki/Context_effect

    Top down design fuels understanding of an image by using prior experiences and knowledge to interpret a stimulus. This process helps us analyze familiar scenes and objects when encountering them. [3] During perception of any kind, people generally use either sensory data (bottom-up design) or prior knowledge of the stimulus (top-down design ...

  4. Predictive coding - Wikipedia

    en.wikipedia.org/wiki/Predictive_coding

    McClelland and Rumelhart's parallel processing model describes perception as the meeting of top-down (conceptual) and bottom-up (sensory) elements. In the late 1990s, the idea of top-down and bottom-up processing was translated into a computational model of vision by Rao and Ballard . [ 3 ]

  5. Top-down - Wikipedia

    en.wikipedia.org/wiki/Top-down

    Top-down reading, is a part of reading science that explains the reader's psycholinguistic strategies in using grammatical and lexical knowledge for comprehension rather than linearly decoding texts. Top-down proteomics, a method for protein analysis; Top-down effects, effects of population density on a resource in a soil food web

  6. Dorsal attention network - Wikipedia

    en.wikipedia.org/wiki/Dorsal_attention_network

    Interaction between dorsal and ventral attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation. [1]The dorsal attention network (DAN), also known anatomically as the dorsal frontoparietal network (D-FPN), is a large-scale brain network of the human brain that is primarily composed of the intraparietal sulcus (IPS) and frontal eye ...

  7. Attentional shift - Wikipedia

    en.wikipedia.org/wiki/Attentional_shift

    Attention can be guided by top-down processing or via bottom up processing. Posner's model of attention includes a posterior attentional system involved in the disengagement of stimuli via the parietal cortex, the shifting of attention via the superior colliculus and the engagement of a new target via the pulvinar. The anterior attentional ...

  8. Feature integration theory - Wikipedia

    en.wikipedia.org/wiki/Feature_integration_theory

    Information acquired through both bottom-up and top-down processing is ranked according to priority. The priority ranking guides visual search and makes the search more efficient. Whether the Guided Search Model 2.0 or the feature integration theory are "correct" theories of visual search is still a hotly debated topic.

  9. Levels of Processing model - Wikipedia

    en.wikipedia.org/wiki/Levels_of_Processing_model

    Conversely, deep processing (e.g., semantic processing) results in a more durable memory trace. [1] There are three levels of processing in this model. Structural processing, or visual, is when we remember only the physical quality of the word (e.g. how the word is spelled and how letters look).
