certain needs have priority over others

criticisms of hierarchy

beyond physiological need and safety need, the priority varies between different cultures

after senses the stimuli, body's response and our interpretation work together and produce an feeling; arousal提供emotion一个生理基础,cognition提供emotion一个标签一个定义

spillover effect

arousal can spill over from one event to the next, influencing our response

the same physiological state can be interpreted as different emotions depending on the cognition effect.

fast pathways of processing of emotion

stimulus information travels from thalamus directly to amygdala with less detail; sometime we experience emotion before we know what cause them

slow pathways of processing of emotion

stimulus informaiton travels from thalamus to cortex then to amygdala and it has more detail but longer processing time

universality of expression

the hypothesis that emotional expressions have the same meaning for everyone
