Question 63

A supervisor's rating of punctuality influences her ratings on other dimensions on the rating form.

The halo effect occurs when an individual's overall impression of a person influences their evaluations of that person's specific traits. In this case, the supervisor's positive or negative rating of punctuality affects her ratings on other unrelated dimensions, exemplifying the halo effect.

A) A supervisor's ratings are compressed into a normal distribution.

This option describes a statistical phenomenon related to how ratings are organized, rather than a psychological bias. It does not illustrate the halo effect, as it does not involve one rating influencing another.

B) A supervisor's ratings are based on critical behaviors of productivity.

While this option hints at a structured approach to evaluating performance, it does not demonstrate the halo effect. The halo effect specifically involves a situation where one characteristic, such as punctuality, unduly influences ratings of other unrelated traits.

C) A supervisor's rating of punctuality influences her ratings on other dimensions on the rating form.

This option perfectly encapsulates the halo effect, where the supervisor's perception of punctuality spills over into her assessments of other areas. This illustrates how an overall impression can skew evaluations of specific attributes.

D) A supervisor tends to give all 4's and 5's on a 5-point scale.

While this option suggests a leniency bias in ratings, it does not specifically relate to the halo effect. Instead, it demonstrates a tendency toward high ratings without indicating that one trait affects another.

Conclusion

Option C is the definitive example of the halo effect, as it directly shows how one evaluation (punctuality) can influence assessments of other unrelated traits. All other options fail to illustrate this psychological phenomenon, focusing instead on statistical methods or biases that do not involve the interconnectedness of ratings.
