Well-conducted research is essential to the advancement of knowledge. Through poor research design, incorrect statistical analysis or inappropriate conclusions, experimenters can conduct virtually useless studies, or worse, call into question the integrity of researchers. However, analysis of poorly conducted research is essential to the improvement of the scientific method. Presented shall firstly be a literature review regarding a growing contemporary body of literature, premised on the association between stressors, management strategies and cortisol levels. Additionally, a replication study examining powerful poses and cortisol levels shall be analysed and critically and constructively evaluated.
Cortisol – commonly known as “the stress hormone” – is a steroid hormone regulated by the hypothalamic-pituitary-adrenal axis, an interaction of endocrine glands thought to be crucial in adapting to behavioural and environmental changes. Cortisol effects many functions within the body, including control of blood sugar levels, regulating the metabolism, reducing inflammation and assisting in immune responses (Randall, 2010; Shu-Fen et al. 2015). The main function of cortisol is to restore homeostasis to the body following stress, and it is the primary hormone responsible for the stress response. Fluctuation of cortisol levels throughout the day is normal for humans, however, sustained high levels of cortisol can have adverse effects. These can include serious health implications…
