• reaction to behaviourism
• way we percieve information, store it and then use it to solve problems rhrough experience learning and memory

• brain recieves constant stream of info as electrical impulses from neurons
• important info amplified by brain as action potentials
• signals sent ot specific part of brain specialized to recieve that info
• if its long enough signal to become even related potential brain gets body to act which cause muscle to contract

cognitive science

• attention and anticipation
• perception
• decision making
• problem solving
• pattern recognition
• memory
• focus and concentration

• how we process sensory info in short period of time (100ms)
• considered subconscious
• objects can shift from perception to awareness

• how we select info for more extensive processing in threshols that range from 120-200ms depending on snesory modality
• anticipation form of early attention

• primary and secondary attention
• serial vs parallel processing
• psychological refactoy period
• bias and selective attention
• anticipation (spatial vs temporal)
• expert attention

novice need more focus on how to do a skill while experts can focus on external anvironment more because motor skills become automatic

looking at different groups in one point of time

• parallel streams of info processed by brain at same time
• during stroop RT is slower and errors are greater

wernickes area

occipital

• delay in attention when 2 stimuli are processed close together
• once we detect the 2nd stimulus we cant process it until we finish the 1st
• even though S! and S2 may be 60-80 ms apart a delay of 200-300ms occurs in responding

ability to direct attention to a stimulus prior to its presentation

• spatial
• temporal

• predict what is going to happen before stimulus appears
• ability to anticipate where in spcae movement will occur
• ex being in position for a pass

• predicting when a stimulus will appear
• ex-timing attention and movement to be at right time and right place

• perception
• attention
• focus and concentration
• memory
• pattern recognition
• problem solving
• decision making

ability to attend what is important with period of mental relaxation

how info stored in the brain and we access it and use it as knowledge for controling thoughts and emotion

ability ro racognize staionary and moving objects, as well as navigating in clutteres environment

how we use perception attention and other cognitive abilities to arrive at a solution

how we chose from alternatives available to us
