The question asks to identify the person who named the "Halo Effect," which is described as a common constant error made by raters or teachers in student assessments using rating scales.
Understanding the Halo Effect
The Halo Effect is a cognitive bias where an initial positive impression of a person influences the perception of their specific traits or abilities. In the context of assessment, this means a teacher's overall positive feeling about a student might lead them to rate that student higher on all specific attributes, even those not directly observed or assessed. Conversely, a negative overall impression can lead to a negative halo effect.
Historical Context of the Halo Effect
The concept of this assessment error was first mentioned by Wells in $1907$. However, the term "Halo Effect" itself was coined and popularized later.
Identifying the Namer of the Halo Effect
The credit for formally naming the Halo Effect goes to Edward Thorndike. In his research published in $1920$, Thorndike described this bias where a general impression about a person, either positive or negative, influences the specific judgments of their character traits. He observed this phenomenon in evaluations of army officers.
Therefore, among the given options, Thorndike ( $1920$ ) is recognized as the individual who named the Halo Effect.
The correct option is:
- Thorndike (1920)
