“…Porter and Lawler (1968) divide rewards into two categories: intrinsic and extrinsic rewards (Alderfer, 1968). According to Katz and Van Maanan (1977), organizational rewards can be divided into three categories: organizational, social, and task rewards (Katz & Van Maanen, 1977). Task rewards such as skill variety, feedback, autonomy (Hackman & Oldham, 1976), role clarity, participation in decision making (Glisson & Durick, 1988;Singh, 1998), and training (Armstrong, 1993) are intrinsic rewards, while organizational and social rewards are referred to as extrinsic rewards.…”
