The Hawthorne effect describes behavioral changes occurring when individuals are aware of being monitored. This phenomenon was observed during studies at the Western Electric Hawthorne Works in the 1920s and 1930s, where worker productivity increased solely due to the awareness of observation.
- Bias in memory recall due to emotional states (B) concerns how emotions impact memory retrieval, a concept distinct from the Hawthorne effect.
- Resistance to change in group dynamics (C) pertains to a group's inclination to resist alterations and is unrelated to the influence of observation.
- The effect of rewards on intrinsic motivation (D) examines how incentives affect motivation but does not account for the impact of observation on performance.
Consequently, the Hawthorne effect is the accurate identification.
