Document Summary
1)attention has to do with many things; inputs, thoughts and actions: is a facilitary and, supressory mechanism. Vs arousal: there are processes that are inhibited while you are sleeping. Attention and arousal are diff things. that doesn"t mean they dont interact with each other. 1. -we have all sorts of bottlenecks. impossible to process everything at the same time. Too much info, u can"t process all the details, hence hard to find waldo. Lack of brain to process everything so attention is good to have: bottleneck exist on sensory(lack of arms, demo of waldo) and cognitive level [we can only have 1 or 2 thoughts at same time. ]. also motor (motor behaviour involving output to muscles, etc) Attention helps us to focus on things that have certain probabilities to be more important than others. Hard to measure attention. only measurable if effects are seen. How do your thresholds of perception change over time.
