The Effect Of Rater Training On Rating Accuracy In Leaderless Group Discussion

Leaderless Group Discussion is an important method of Assessment Center ,and is an effective personnel test. The raters evaluate their abilities by watching their behaviors to find which one is competent for a position in the simulation condition. Rater training can improve the rating accuracy. Frame-of-reference Training(FOR) and Behavioral observation Training (BOT)are two most effective method. The aims of the study are as follows:(1) We examined the utility of frame-of- reference( FOR) training and behavioral observation training( BOT) for enhancing rating accuracy and behavioral accuracy in the study by experiment. (2) If we connected FOR and BOT, it will result in higher rating accuracy than FOR only.(3)The FOR+BOT group will have higher behavioral accuracy.We use experimental method in the study. The Participants are 123 students of Psychology Department and Education Technology Department in Guangxi Normal University. Participants were randomly assigned to either( a) FOR training,( b) FOR training + BOT, or( c) control training. SPSS Windows for 10.0 is used to analyze the data.Results indicated (1) Training group led to significant enhancements in rating accuracy. (2) FOR training group and FOR+BOT group provided higher rating dimension differentiation than control training. And there is no significant difference between FOR training and FOR+BOT training.The reason is that there may not have been sufficient opportunity to employ BOT techniques. (3) However, contrary to predictions, the inclusion of BOT did not lead to significant increases in rating accuracy beyond FOR training alone. (4) We also obtained evidence that there is no significant difference among three groups on DEL variable. That is to say, Training didn't provided higher ratee differentiation. (5)FOR+BOT trained participants also produced significantly higher levels of behavioral accuracy compared to other conditions.
