Psychologists Often Rely on Rating Scales for the Assessment of Children's

Psychologists often rely on rating scales for the assessment of children's behavior. One potential problem with rating scales is known as the "halo effect." Which of the following scenarios best describes ratings possibly contaminated by the halo effect?

A) A child receives a 4 out of 5 rating on one area of personality functioning and receives the same rating on every other area of personality functioning.
B) A child was evaluated with a rating scale the year before and was rated 4 out of 5 on a particular area of behavior. The same rating scale is used on the same child a year later, and the rating remains the same.
C) Two children are rated by the same person with the same rating scale. The first child receives high ratings, and so does the second child.
D) Two children are rated by the same person with the same rating scale. After giving a poor rating to one child, the rater, not wanting to have poor ratings across the board, gives another child a high rating.
