Electrophysiological correlates of confidence differ across correct and erroneous perceptual decisions.

Every decision we make is accompanied by an estimate of the probability that our decision is accurate or appropriate. This probability estimate is termed our degree of decision confidence. Recent work has uncovered event-related potential (ERP) correlates of confidence both during decision formation and after a decision has been made.

Preoperative assessment of patients undergoing elective noncardiac surgery.

Patient comorbidities and risk factors are important to the success of any operation, and knowing about them before surgery can help clinicians anticipate perioperative complications and optimize patient conditions. This article describes key considerations in the preoperative assessment of patients undergoing elective noncardiac surgery and describes risk stratification for common conditions.

Trade-offs between three forest ecosystem services across the state of New Hampshire, USA: timber, carbon, and albedo.

Forests are more frequently being managed to store and sequester carbon for the purposes of climate change mitigation. Generally, this practice involves long-term conservation of intact mature forests and/or reductions in the frequency and intensity of timber harvests. However, incorporating the influence of forest surface albedo often suggests that long rotation lengths may not always be optimal in mitigating climate change in forests characterized by frequent snowfall.
