Practicing is an activity that accounts for the highest levels of musical expertise, but one that many musicians do not typically—or at least consistently—carry out. Most people have done some kind of independent practicing (or academic studying or athletic training) in their lives and have likely heard platitudes such as “Practice makes perfect.” Such folk knowledge tends to suggest that quantity of practice is the most important factor. Unfortunately, popular handling of psychological research has largely reinforced this misconception. More careful consideration of the research, however, shows that although developing musicians certainly must make time for practice, the efficiency and deliberateness of time spent are also crucial. This chapter begins by defining “deliberate practice” as the type of practicing that optimally contributes to musical skill acquisition. Through consistent practice over time, skills that began as highly conscious and effortful progress to ultimately becoming fluently and automatically performed. Rather than striving to simply amass hours of practice time, musicians are encouraged to be more productive and efficient by strategically planning, executing, and reflecting on their practice.

A description of two cases from my time as a school psychologist in the middle of the 1950s forms the background to the following question: Has anything important happened since then in psychological research to help us to a better understanding of how and why individuals think, feel, act, and react as they do in real life and how they develop over time? The studies serve as a background for some general propositions about the nature of the phenomena that concerns us in developmental research, for a summary description of the developments in psychological research over the last 40 years as I see them, and for some suggestions about future directions.

Many outcome variables in developmental psychopathology research are highly stable over time. In conventional longitudinal data analytic approaches such as multiple regression, controlling for prior levels of the outcome variable often yields little (if any) reliable variance in the dependent variable for putative predictors to explain. Three strategies for coping with this problem are described. One involves focusing on developmental periods of transition, in which the outcome of interest may be less stable. A second is to give careful consideration to the amount of time allowed to elapse between waves of data collection. The third is to consider trait-state-occasion models that partition the outcome variable into two dimensions: one entirely stable and trait-like, the other less stable and subject to occasion-specific fluctuations.

Purpose The current study tested whether the difficulties of children with specific language impairment (SLI) in skill acquisition are related to learning processes that occur while practicing a new skill or to the passage of time between practice and later performance. Method The acquisition and retention of a new complex grapho-motor symbol were studied in 5-year-old children with SLI and peers matched for age and nonverbal IQ. The children practiced the production of the symbol for 4 consecutive days. Retention testing took place 10 days later. Results Children with SLI began each practice day slower than their peers but attained similar levels of performance by its end. Although they increased their performance speed within sessions more than their peers, they did not retain their learning as well between sessions. The loss in speed was largest in the 10-day retention interval. They were also less accurate, but accuracy differences decreased over time. Between-session group differences in speed could not fully be accounted for based on fine motor skills. Conclusions In spite of effective within-session learning, children with SLI did not retain the new skill well. The deficit may be attributed to task forgetting in the presence of delayed consolidation processes.

Rules of evidence are designed to facilitate trials by controlling what evidence may be presented at trial. Those rules came into being, and evolved over time, due to changes in trial process and structure – especially following the rise of adversarial procedure, whereby control over the marshaling and presentation of facts shifted from judges to lawyers. Refinements and reforms continue to be undertaken to try to improve the scope and clarity of the rules. Trial judges must not only apply the rules, they also have the discretion to make rulings in light of their expectations of the impact they think the evidence will have on jurors. This task involves metacognition: one human trying to estimate the thought processes of others. Thus, evidence rulemakers have been and are, effectively, applied psychologists. The rules of evidence reflect their understanding of the psychological processes affecting, and capabilities and limitations of witnesses, lawyers and jurors. Psychological research and methods provide an additional source of insight and assistance in that endeavor. Better psychological understanding should lead to more effective rules. Psychologists typically employ the scientific method: empirically testing hypotheses in an effort to discover which are valid understandings of how people perceive, store, and retrieve information. To evaluate evidence rules, one could conduct experiments directly on a rule, or borrow from existing knowledge developed in basic research and see whether those understandings support existing or proposed evidence rules.

There is a growing public health need for effective preventive interventions against dengue, and a safe, effective and affordable dengue vaccine against the four serotypes would be a significant achievement for disease prevention and control. Two tetravalent dengue vaccines, Dengvaxia (CYD-TDV—Sanofi Pasteur) and DENVax (TAK 003—Takeda Pharmaceutical Company), have now completed phase 3 clinical trials. Although Dengvaxia resulted in serious adverse events and had to be restricted to individuals with prior dengue infections, DENVax has shown, at first glance, some encouraging results. Using the available data for the TAK 003 trial, we estimate, via the Bayesian approach, vaccine efficacy (VE) of the post-vaccination surveillance periods of 12 and 18 months. Although better measurement over a long time was expected for the second part of the post-vaccination surveillance, variation in serotype-specific efficacy needs careful consideration. Besides observing that individual serostatus prior to vaccination is determinant of DENVax vaccine efficacy, such as for Dengvaxia, we also noted, after comparing the VE estimations for 12- and 18-month periods, that vaccine efficacy is decreasing over time. The comparison of efficacies over time is informative and very important, and brings up the discussion of the role of temporary cross-immunity in dengue vaccine trials and the impact of serostatus prior to vaccination in the context of dengue fever epidemiology.

Student acquisition of psychomotor skills in athletic training is diffcult, particularly those pertaining to non-orthopedic injuries and illnesses, which are less common in our patient populations. We provide examples of lesson plans to improve physical examination of the thorax and abdomen. Each lesson (the scratch test, utilization of a noise-immune stethoscope, tactile fremitus, and intent auscultation) allows students to engage in performance of the skill and expand contextual knowledge to enhance skill acquisition and learning.

Social isolation and nonparticipation in the community are chronic issues for adults with schizophrenia spectrum disorders that can lead to poorer health outcomes. The Independence through Community Access and Navigation (I-CAN) intervention was developed as a theoretically grounded intervention that uses motivational interviewing to understand the interests and motivations of clients for participation. The intervention is designed to support participation in community-based activities by providing access and skill acquisition in a community environment. Participation between the recreational therapist and the participant decreases over time to encourage the individual to begin to independently access his or her community. This article presents the treatment planning steps and the implementation protocol for the I-CAN intervention.

Music has played a pivotal role in the development of the theory of expert performance with much of the foundational research conducted with musical experts. This chapter explores the role music played in the development of the theory and issues arising from the original research that have not yet been fully addressed. The definitions of musical expertise and deliberate practice in music are explored. Because the musical field has not adopted a consistent definition of expertise, operational definitions in the research can be somewhat inconsistent. A preliminary hierarchical system is proposed. The chapter concludes with consideration of other variables, such as genetics, that could interact with deliberate practice to develop expertise in the musical domain. Current thinking is that deliberate practice is important, but insufficient to explain expertise. The development of musical experts may be more complex than either the amount of deliberate practice or genetics can explain.
