Final answer:
Psychological factors like belief, known as the placebo effect, and attention from others, known as the Hawthorne effect, can have significant effects on performance, demonstrating the effectiveness of psychological elements in performance psychology training.
Step-by-step explanation:
A fact in performance psychology training is that psychological factors, such as belief and perception, can significantly impact an individual's performance. Research, such as that referenced by Arthur et al. (2003), demonstrates that believing one has taken a performance-enhancing substance can lead to nearly the same performance improvements as actually taking the substance. This is a manifestation of the placebo effect, wherein the power of belief impacts physical performance.
Additionally, the Hawthorne effect shows that individuals perform better when they are observed and given attention by researchers or supervisors. This indicates that human interaction and perception play a considerable role in improving performance beyond just the physical implementation of training or financial resources. Ultimately, psychological elements such as belief, attention, and the structure of the work environment are pivotal in enhancing performance within organizations.
