This work provides a complete theory of emotional processes, explaining how different emotions are elicited and expressed, and how the emotional range of individuals develops over their lifetime. The author's approach puts emotion in a central role as a complex, patterned, organic reaction to both daily events and long-term efforts on the part of the individual to survive, flourish, and achieve. In his view, emotions cannot be divorced from other functions - whetherbiological, social, or cognitive - and express the intimate, personal meaning of what individuals experience. As coping and adapting processes, they are seen as part of the ongoing effort to monitor changes, stimuli, and stresses arising from the environment.
