The role of deliberate practice in the acquisition of expert performance.

Abstract

The theoretical framework presented in this article explains expert performance as the end result of individuals' prolonged efforts to improve performance while negotiating motivational and external constraints. In most domains of expertise, individuals begin in their childhood a regimen of effortful activities (deliberate practice) designed to optimize improvement. Individual differences, even among elite performers, are closely related to assessed amounts of deliberate practice. Many characteristics once believed to reflect innate talent are actually the result of intense practice extended for a minimum of 10 years. Analysis of expert performance provides unique evidence on the potential and limits of extreme environmental adaptation and learning.Our civilization has always recognized exceptional individuals, whose performance in sports, the arts, and science is vastly superior to that of the rest of the population. Speculations on the causes of these individuals' extraordinary abilities and performance are as old as the first records of their achievements. Early accounts commonly attribute these individuals' outstanding performance to divine intervention, such as the influence of the stars or organs in their bodies, or to special gifts (Murray, 1989). As science progressed, these explanations became less acceptable. Contemporary accounts assert that the characteristics responsible for exceptional performance are innate and are genetically transmitted.The simplicity of these accounts is attractive, but more is needed. A truly scientific account of exceptional performance must completely describe both the development leading to exceptional performance and the genetic and acquired characteristics that mediate it. This account must specify the critical differences between exceptional and ordinary performers. It must also show that any postulated genetic differences can be hereditary and are plausible from an evolutionary perspective.

Therefore, to better understand expert and exceptional performance, we must require that the account specify the different environmental factors that cou...

Dedicated time for deliberate practice: one emergency medicine program’s approach to point-of-care ultrasound (PoCUS) training

“…Integration of modern educational frameworks (Ericsson's Deliberate Practice, 6 Competency-Based Medical Education 8 ) can facilitate skill acquisition. After redesigning our PoCUS curriculum around the precepts of deliberate practice, our residents were able to achieve competency in all basic PoCUS applications during their junior years of training.…”

The psychology of intelligence analysis: Drivers of prediction accuracy in world politics.

“…Similar results occurred with cutoffs of 30 and 40 questions. This analysis is based on only 2 years of deliberative practice, not 10,000 hr (i.e., the length of deliberative practice necessary to achieve expertise, according to Ericsson et al, 1993). Nonetheless, the difficulty of the questions and the breadth of topics suggest that one would do poorly in our tournament without some degree of sustained effort and engagement.…”

Review article: Closing the research gap at the interface of learning and clinical practice

“…73 Total hours of active practice fell significantly short of the 10,000 mark found in individuals who have attained ''international-level performance'' in other sectors of competence, such as athletes, professional musicians, and chess players. 4,[74][75][76][77] The absence of research on the hours and the processes involved in the acquisition of clinical skills makes these proxies from other domains of performance appealing, but their applicability to medical education has not been studied formally; at the same time, much of the research cited in Ericsson's 2004 comprehensive review about the acquisition of physician competence was conducted in the 1960s. 77 There has been little recent work in this important area, including work on the benefits of simulation, rehearsal, and ''deliberate and guided practice'' in medical education.…”
