Social information processing and job characteristics.

This study simultaneously tested 2 theories that attempt to explain differences in job satisfaction: job characteristics theory (Hackman & Oldham, 1976) and social information processing theory (Salancik & Pfeffer, 1978). The theories were tested using data collected from the civilian employees of the public works division at a U.S. military base. The results indicated that individuals' social environments had significant effects upon their attitudes. Multiple social networks were used to operationalize individuals' social environments. The results also suggested that job characteristics had an independent main effect upon job satisfaction, in addition to the effects of the social environment. Based on prior research, employees' past experience and self‐monitoring were tested as moderators of the effects of the social environment, and growth need strength was tested as a moderator of the effects of job characteristics upon job satisfaction. Only self‐monitoring was found to have a significant moderating effect on the relationship between information from the social environment and job satisfaction, and growth need strength had no significant moderating effect.     

Consumption-leisure tradeoffs in pigeons: Effects of changing marginal wage rates by varying amount of reinforcement

Pigeons' rates of responding and food reinforcement under simple random-ratio schedules were compared with those obtained under comparable ratio schedules in which free food deliveries were added, but the duration of each food delivery was halved. These ratio-with-free-food schedules were constructed so that, were the pigeon to maintain the same rate of responding as it had under the simple ratio schedule, total food obtained (earned plus free) would remain unchanged. However, any reduction in responding would reduce total food consumption below that under the simple ratio schedule. These “compensated wage decreases” led to decreases in responding and decreases in food consumption, as predicted by an economic model of labor supply. Moreover, the reductions in responding increased as the ratio value increased (i.e., as wage rates decreased). Pigeons, therefore, substituted leisure for consumption. The relationship between these procedures and negative-income-tax programs is noted.
