Final answer:
Richard Lazarus's theory on stress emphasizes appraisal as the first step in experiencing stress.
Step-by-step explanation:
The first step in experiencing stress, according to Richard Lazarus's theory, is called appraisal. Lazarus emphasized the importance of how we appraise or judge-demanding or threatening events, which in turn influences our reactions to these events.
This process involves two kinds of appraisals: primary appraisal and secondary appraisal. Primary appraisal involves judging the degree of potential harm or threat to well-being that a stressor might entail. Secondary appraisal involves judging the options available to cope with the stressor and how effective these options will be.
