Assessor cognitive processes in an operational assessment center.

Area of Science:

• Organizational Psychology
• Human Resources Management
• Assessment Center Methods

Background:

• Assessment centers are widely used for employee selection and development.
• Previous research has debated whether ratings reflect situational specificity or method bias.
• Understanding assessor cognitive processes is crucial for accurate performance evaluations.

Purpose of the Study:

• To further test the situational specificity interpretation of exercise effects on assessment center ratings.
• To compare salient dimension versus general impression models of assessor evaluations during exercises.

Main Methods:

• Utilized data from assessment center exercises.
• Analyzed the relationship between exercise performance, overall impressions, and dimensional ratings.
• Employed statistical models to test competing hypotheses.

Main Results:

• Findings strongly supported the situational specificity hypothesis.
• Evidence indicated that general impression models better explain assessor cognitive processes.
• Overall candidate performance evaluations significantly influenced specific dimension ratings.

Conclusions:

• Assessor ratings in assessment centers are more influenced by situational factors and overall impressions than method bias.
• General impressions of candidate performance appear to drive subsequent dimensional ratings.
• These findings have implications for improving the validity and reliability of assessment center evaluations.
