Effects of rater conscientiousness on evaluations of task and contextual performance of older and younger co-workers

The possibility for age discrimination and stereotypes to affect performance evaluations is rising. Although careful evaluations might be expected from conscientious raters, little is known about whether they might show more or less bias towards certain age groups. Therefore, in our study using a time-lagged design, we investigated the effects of rater conscientiousness on the performance evaluations of younger and older actual co-worker (N = 242). We found that raters who were more conscientious provided higher ratings for older workers than for younger workers on task performance and organizational citizenship behaviours. Specifically, we tested the model of mediated moderation, in which the relation between rater conscientiousness and ratee age predicts ratee-perceived conscientiousness, which in turn predicts performance ratings. The model was significant for older ratees, but not for younger ratees. We discuss our results in terms of the “similar to me” effects and implications for organizational practices.     

The Psychological Benefits of Humor

In Men and Their Religion: Honor, Hope, and Humor (2002), I proposed that men have two primary ways of being religious—the religion of honor and the religion of hope. I also proposed that because these two religions do not always have their desired outcomes, men have developed a third way of being religious, the religion of humor. In A Time To Laugh (2005) I have expanded on my claim in Men and Their Religion that if men have three religions—honor, hope, and humor—the greatest of these is humor. In the course of doing the necessary research for a book on humor, I acquired and read a few books and a host of articles that explored the psychological benefits of humor. While I did not report on these studies in the book, I believe they are relevant to the assumption that a religion will have psychological benefits for those who embrace it. This article therefore provides a review of empirical studies of the psychological benefits of humor in order to answer the question whether a religion of humor is likely to have psychological benefits and, if so, what these might be.     

Attention and “visual field dependency” in the pigeon

Three pigeons were trained in an upright conditioning chamber to peck a key transilluminated by a vertical line. This training was followed by a line orientation generalization test. During the test, the chamber was tilted laterally 22.5 degrees from upright. The chamber floor remained horizontal with respect to gravity. Under these conditions, the subjects responded more often in the presence of a visually vertical (parallel to chamber walls) line orientation than in the presence of a gravitationally vertical line orientation. Subsequent reinforcement of pecking in the presence of a line that was always gravitationally vertical but not always visually vertical temporarily abolished this "visual field dependency" and resulted in generalization gradients with peak responding in the presence of the gravitationally vertical line orientation. The results are discussed in terms of selective attention to the gravitational and visual components of line orientation.
