the hypothalamo-pituitary-adrenal axis but there are a few cases in which the problem of origination is elsewhere in the body. In a healthy individual‚ the hyptothalamus releases corticotropin- releasing hormone (CRH)‚ which in turn signals the anterior lobe of the pituitary gland to release adrenocoricotropin hormone (ACTH). ACTH then stimulates the release of glucocorticoid cortisol from the zona fasciculata/reticularis of the adrenal gland. The release of cortisol exerts negative feedback on

The Relationship Between Extraversion and Time Perception: A Correlational Study Abstract Eysenck stated that extraverts need more stimulation (e.g. engaging‚ loud‚ exciting situations) for optimal performance‚ whereas introverts require minimal stimulation (e.g. quiet isolation). Does the extravert’s reliance on constant activity mean that they will underestimate a period of time if they are not in a stimulating situation? Will introverts appreciate the lack of stimulation and overestimate that
