Specifically, he identified two essential factors in an essay in which he discusses the cognitive aspects of emotion: "first, what is the nature of the cognitions (or appraisals) which underlie separate emotional reactions (e.g. fear, guilt, grief, joy, etc.). Second, what are the determining antecedent conditions of these cognitions." (Lazarus, Averill, & Opton (1970, p. 219) These two aspects are absolutely crucial in defining the reactions that stem from the initial emotions that underlie the reactions. Moreover, Lazarus specified two major types of appraisal methods which sit at the crux of the appraisal method: 1) primary appraisal, directed at the establishment of the significance or meaning of the event to the organism, and 2) secondary appraisal, directed at the assessment of the ability of the organism to cope with the consequences of the event. These two types go hand in hand as one establishes the importance of the event while the following assesses the coping mechanisms which Lazarus divided up into two parts: direct actions and cognitive reappraisal processes.
