| Abstract: | It was suggested that the extremity of the scale values associated with standards used to represent effective and ineffective performance in Mixed Standard Scales may affect the nature of performance ratings derived from MSS responses and decisions based on MSS ratings. When the extremity of standards was experimentally manipulated, it was found that standard extremity affects both the level of performance ratings and the proportion of logically inconsistent response patterns observed. In addition, standard extremity appears to affect the rankings on performance of ratees. The implications of these observations for the development of Mixed Standard Scales were discussed. |
