In addition to environmental influences (chaps. 4 to 8) and social effects (in the previous section), happiness also derivers in part from the ways in which a person processes the information that is available in a particular setting. Psychologists’ models of information processing in this area have mainly addressed negative stimuli and way that people might cope with those. For example, the appraisal-coping model (e.g.,Lazarus, 1999); smith, Haynes, Lazarus, & Pope, 1993) emphasized the mental processes through which people initiate different kinds of coping behavior. “Primary” appraisal was viewed as the assessment of an event’s threat or value, and the creation of behaviors to change environmental conditions perceived as undesirable was described as “secondary” appraisal. The framework presented by Daniels, Harris, and Briner (2004) also focuses on unpleasant affect and possible coping procedures, specifying patterns of controlled or automatic processing linked to the development of relevant mental models.
