Document Summary
), overt, and covert attention: overt = eyes moving to focus on something, covert = eye not moving (e. g. when you tell your friend to look at something but not make it too obvious) In these theories all stimuli are processed fully then attention determines which information reaches consciousness. In general, both models suggest information can be boosted/filtered at various levels of processing depending on the needs for a particular task or set of circumstances. Endogenous attention: endogenous attention is voluntary and depends on goals, expectation, knowledge, or instructions 9e. g. cued visual spatial attention, a valid cue speeds up a reaction to target stimulus, while invalid cue slows reaction. In endo attention you have to directly attend to something in the environment. Neuroscience of sensory attention: measuring brain responses to stimuli reveals brain areas are modulated by attention, generic sensory input bottom up processing attentional control network bottom up processing.
