Document Summary
Debate (teams in favor and against) topic: electronic performance monitoring. Multisource (e. g, peer, supervisor, self and subordinate ratings of performance) The immediate supervisor is, by far the most popular source of job performance ratings: but, there is an increasing emphasis being placed on ratings from other sources (multisource or 360-degree ratings) Harris and schaubroeck (1988): differences in peer supervisor and self. Range restriction (rr) (comes up often in meta-analysis) Occurs when the range of scores on a variable is narrower than it should be: e. g. If people inflate their self-ratings of performance to the point where many people achieve the highest possible score : hand out number 1 given in class. Range restriction has the effect of weakening he correlation between the range-restricted variable and other variables: example: rr would weaken correlations of self-ratings of performance with peer and supervisor ratings of performance.
