Somewhat slower, the hypothalamus–pituitary–adrenal axis is activated, releasing corticotropin-releasing hormone (CRH) from the hypothalamus which stimulates the anterior pituitary to secrete adrenocorticotropic hormone (ACTH).ACTH in turn causes the adrenal cortex to produce cortisol and release it into the blood stream.Based on these empirical findings, we will finally discuss the implications of stress effects on learning and memory processes for the classroom.Difficult situations in the classroom such as exams or interpersonal conflicts can challenge or exceed the coping strategies or resources available and thus threaten our homoeostasis, our inner balance, leading us to feel ‘stressed’.

While stress (indicated as red flash) long before encoding impairs memory formation, stress shortly before or after the presentation of new information generally enhances subsequent memory performance.In addition to its effects on memory encoding and retrieval, stress appears to impair this integration of new information into existing knowledge structures.Emotionally arousing events are typically very well-remembered.Moreover, distinct memory stages, i.e., encoding, consolidation or retrieval may be differently affected by these time-dependent physiological changes after a stressful encounter.In the next section, we will portray the time-dependent effects of stress on learning and memory, taking into account both the specific memory stage affected and the temporal proximity between the stressful event and the memory formation or retrieval process (Figure 2).Exams, tight deadlines and interpersonal conflicts are just a few examples of the many events that may result in high levels of stress in both students and teachers.Research over the past two decades identified stress and the hormones and neurotransmitters released during and after a stressful event as major modulators of human learning and memory processes, with critical implications for educational contexts.In sharp contrast, stress before memory retrieval impairs the recall of information learned previously which may directly affect performance at exams.In education, knowledge needs to be frequently updated by new facts or concepts relating to prior knowledge.Therefore, a large number of studies has been conducted to better understand how stress affects learning and memory.The effects of stress were found to be complex, though, with stress having both enhancing and impairing effects on memory, depending on the specific memory process or stage that is affected by stress This review summarises the current state of knowledge on the impact of (acute) stress on memory and derives implications for educational settings from these laboratory findings.
