Everyday cognition: age and intellectual ability correlates

The primary aim of this study was to examine the relationship between a new battery of everyday cognition measures, which assessed 4 cognitive abilities within 3 familiar real-world domains, and traditional psychometric tests of the same basic cognitive abilities. Several theoreticians have argued that everyday cognition measures are somewhat distinct from traditional cognitive assessment approaches, and the authors investigated this assertion correlationally in the present study. The sample consisted of 174 community-dwelling older adults from the Detroit metropolitan area, who had an average age of 73 years. Major results of the study showed that (a) each everyday cognitive test was strongly correlated with the basic cognitive abilities; (b) several basic abilities, as well as measures of domain-specific knowledge, predicted everyday cognitive performance; and (c) everyday and basic measures were similarly related to age. The results suggest that everyday cognition is not unrelated to traditional measures, nor is it less sensitive to age-related differences.     

Use of relaxation skills in differentially skilled athletes

ObjectivesTo examine the use of relaxation skills by differentially skilled athletes in relation to the deliberate practice framework.DesignDifferentially skilled athletes completed a survey about their use of relaxation skills.Method150 athletes representing three skill levels (recreational, college, and professional) completed the deliberate relaxation for sport survey, which assessed relaxation on three deliberate practice dimensions (relevancy, concentration, and enjoyment); time spent in different relaxation skills in a recent typical week; and functions of relaxation.ResultsAthletes perceived relaxation as relevant to performance, requiring concentration, and enjoyable, and the relationships between these dimensions were positive. Professional and college athletes perceived relaxation as more relevant to effective competition than recreational athletes. Professional athletes engaged in more relaxation in a typical week than college and recreational athletes. In a typical week, autogenic, eastern, and muscle relaxation types were used least, deep breathing, meditation, and imagery relaxation types moderately, and stretching most. Athletes reported the primary functions of relaxation were to cope with competitive anxiety and promote recovery but relaxation was also reported to be used to cope with “everyday” anxieties associated with being an athlete. More physical (e.g., muscle relaxation) than mental relaxation types were used in relation to coping with competitive anxiety, whereas more mental (e.g., meditation) than physical relaxation types were used in relation to coping with everyday anxiety.ConclusionsThe study provides support for the sport-specific framework of deliberate practice in relation to use of relaxation skills and informs the current understanding of self-regulation by athletes.     

Deliberate practice predicts performance over time in adolescent chess players and drop‐outs: A linear mixed models analysis

In this study, the longitudinal relation between deliberate practice and performance in chess was examined using a linear mixed models analysis. The practice activities and performance ratings of young elite chess players, who were either in, or had dropped out of the Dutch national chess training, were analysed since they had started playing chess seriously. The results revealed that deliberate practice (i.e. serious chess study alone and serious chess play) strongly contributed to chess performance. The influence of deliberate practice was not only observable in current performance, but also over chess players' careers. Moreover, although the drop‐outs' chess ratings developed more slowly over time, both the persistent and drop‐out chess players benefited to the same extent from investments in deliberate practice. Finally, the effect of gender on chess performance proved to be much smaller than the effect of deliberate practice. This study provides longitudinal support for the monotonic benefits assumption of deliberate practice, by showing that over chess players' careers, deliberate practice has a significant effect on performance, and to the same extent for chess players of different ultimate performance levels. The results of this study are not in line with critique raised against the deliberate practice theory that the factors deliberate practice and talent could be confounded.

How Do Creative Experts Practice New Skills? Exploratory Practice in Breakdancers

How do expert performers practice as they develop creatively? This study investigated the processes involved in the practice of new skills by expert breakdancers. A great deal of evidence supports the theory of “deliberate practice” (Ericsson, Krampe, & Tesch‐Römer, 1993, Psychological Review, 100, 363) in skill acquisition; however, expert creative performers may emphasize other forms of practice for skill development. Four case studies collected through fieldwork and laboratory observation were analyzed to evaluate expert dancers’ practice processes as they developed proficiency in new, specific skills. We focused on three aspects of learning: the degree of skill acquisition, the content of skills included in practice, and dancers’ stated purposes for practicing. The results showed that dancers’ practice improved skills (as suggested by deliberate practice) and engaged the exploration of new, original skills, along with coordinating skills within performance. In their practice, these dance experts went beyond deliberative practice to highly exploratory processes for skill development.     

The problem of rehearsal or mental practice

The present study examines several methodological and conceptual problems which in the past have made it difficult to accept the hypothesis that mental practice facilitates behavioral skill. An experiment on skill in speech production is then reported which overcomes the methodological problems. Subjects practice producing a sentence at maximal rate either mentally (mental practice) or overtly (physical practice) and then produced a transfer sentence which was either related or unrelated. The maximal rate of speech was faster for related than unrelated transfer sentences, and the degree of transfer for the mental and physical practice conditions was equivalent. A theory was developed to explain these results and overcome the conceptual problems outlined in the introduction. Implications of the theory for several related phenomena are discussed: rehearsal, errors in action, automatization, control processes in motor skills, speed-up as a function of practice, the relative advantages of physical vs. mental practice, and the evoked potentials accompanying mental rehearsal of an action.     

Deliberate practice in dogs: a canine model of expertise

The acquisition of expertise is an area of controversy between those who lean more toward learning and those who lean more toward talent. Because the genetics and early life experiences of humans are not open to direct manipulation, human studies are of limited use in this debate. Studies using nonhumans as expert models may prove useful in resolving this dispute. For nonhumans to be considered proper models of human experts, there must be evidence supporting a shared acquisition mechanism. A candidate mechanism is deliberate practice. The author tested the deliberate practice theory of expertise acquisition on dogs competing in the sport of agility. The author examined the relationships between amounts of accumulated deliberate practice and agility performance measures. The author found there was a statistically significant relationship between the amount of deliberate practice and measured performance in agility dogs, even when controlling for sex, breed group, age, and height.     

Understanding deliberate practice in preschool-aged children

Deliberate practice is essential for skill acquisition and expertise and may be a direct consequence of episodic foresight. However, little is known about how deliberate practice develops in children. We present two experiments testing children's ability to selectively practise a behaviour that was going to be useful in future and to reason about the role of practice in skill formation. Five-year-olds demonstrated an explicit understanding of deliberate practice both in selectively choosing to practise a future-relevant skill and in predicting skill change in others based on their practice. Four-year-olds showed some capacities, but failed to demonstrate consistent understanding of the relationship between practice and skill improvement. Children's understanding of this relationship was significantly related to their understanding of how information leads to knowledge, suggesting that both may draw on similar cognitive developmental changes.     

Testing assumptions of deliberate practice theory relevance, effort, and inherent enjoyment of practice with a novel task: study II

This study examined three assumptions of the theory of deliberate practice: that deliberate practice is perceived as relevant for improving performance and that it requires effort, but that it is not perceived as being inherently enjoyable. Of particular interest was how these perceptions change as practice difficulty changes. 30 college undergraduates practiced two different maze memorization and replication tasks and rated the practice relevance for improving performance on the task, the practice effort, and the inherent enjoyment of practice. The findings for each of the assumptions were consistent with those suggested by the theory and also showed that these perceptions are subject to the current performance on an activity and the difficulty of the practice.     

Skill acquisition in music performance: relations between planning and temporal control

We investigated the acquisition of music performance skills in novice and expert pianists. Temporal disruptions in novice performances coincided with constraints in planning capacities. Child and adult pianists ranging in age (9-26 years), training (3-15 years) and sight-reading ability learned to perform a novel musical piece in eleven practice trials. Computer-detected pitch and timing errors revealed: (1) gradual improvements in performance tempo and pitch accuracy with skill level and practice, generally fitting a power function; (2) a relative-timing/pitch accuracy trade-off and high incidence of simultaneous pitch/time errors; (3) improvements in relative timing (temporal continuity, underlying beat, metrical structure) with skill and practice; and (4) increased anticipatory behavior and a greater range of planning with skill and practice. A strong positive relationship between the mastery of temporal constraints and planning abilities within performance suggests that these two cognitive indicators are closely related and may arise from segmentation processes during performance. Examination of sequence timing may explicate planning abilities that underlie many complex skills.     

The Problem of Rehearsal or Mental Practice

The present study examines several methodological and conceptual problems which in the past have made it difficult to accept the hypothesis that mental practice facilitates behavioral skill. An experiment on skill in speech production is then reported which overcomes the methodological problems. Subjects practiced producing a sentence at maximal rate either mentally (mental practice) or overtly (physical practice) and then produced a transfer sentence which was either related or unrelated to the practiced sentence. The maximal rate of speech was faster for related than unrelated transfer sentences, and the degree of transfer for the mental and physical practice conditions was equivalent.

A theory was developed to explain these results and overcome the conceptual problems outlined in the introduction. Implications of the theory for several related phenomena are discussed: rehearsal, errors in action, automatization, control processes in motor skills, speed-up as a function of practice, the relative advantages of physical vs. mental practice, and the evoked potentials accompanying mental rehearsal of an action.     

Execution and pauses in writing narratives: processing time, cognitive effort and typing skill

At the behavioural level, the activity of a writer can be described as periods of typing separated by pauses. Although some studies have been concerned with the functions of pauses, few have investigated motor execution periods. Precise estimates of the distribution of writing processes, and their cognitive demands, across periods of typing and pauses are lacking. Furthermore, it is uncertain how typing skill affects these aspects of writing. We addressed these issues, selecting writers of low and high typing skill who performed dictation and composition tasks. The occurrences of writing processes were assessed through directed verbalization, and their cognitive demands were measured through interference in reaction times (IRT). Before writing a narrative, 34 undergraduates learned to categorize examples of introspective thoughts as different types of activities related to writing (planning, translating, or revising). Then, while writing, they responded to random auditory probes, and reported their ongoing activity according to the learned categories. Convergent with previous findings, translating was most often reported, and revising and planning had fewer occurrences. Translating was mostly activated during motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes can be characterized as being typical of pauses, since translating was activated to a similar extent as the other two processes. Regarding cognitive demands, revising is likely to be the most demanding process in narrative writing. Typing skill had an impact on IRTs of motor execution. The demands of execution were greater in the low than in the high typing skill group, but these greater demands did not affect the strategy of writing processes activation. Nevertheless, low typing skill had a detrimental impact on text quality.     

Expertise and the evolution of consciousness

This paper argues that expertise can be used as an indicator of consciousness in humans and other animals. The argument is based on the following observations: (1) expertise and skill acquisition require deliberate practice; and (2) the characteristics of deliberate practice such as performance evaluation against a more proficient model, retention of voluntary control over actions, self-monitoring, goal-setting, error-detection and correction, and the construction of hierarchically organized retrieval structures are outside of the currently understood bounds of unconscious processing. Thus, to the extent that evidence of expertise exists in an organism, evidence of conscious experience is also present. Two important implications arise from this conclusion: (1) evidence of expertise can be used as the basis for cross-species comparisons of consciousness; and (2) the evolution of human consciousness can be assessed using fossil evidence of skilled behavior as a measure of consciousness.     

On the role of passion in performance

The present paper reports two studies designed to test the Dualistic Model of Passion with regard to performance attainment in two fields of expertise. Results from both studies supported the Passion Model. Harmonious passion was shown to be a positive source of activity investment in that it directly predicted deliberate practice (Study 1) and positively predicted mastery goals which in turn positively predicted deliberate practice (Study 2). In turn, deliberate practice had a direct positive impact on performance attainment. Obsessive passion was shown to be a mixed source of activity investment. While it directly predicted deliberate practice (Study 1) and directly predicted mastery goals (which predicted deliberate practice), it also predicted performance-avoidance and performance-approach goals, with the former having a tendency to facilitate performance directly, and the latter to directly negatively impact on performance attainment (Study 2). Finally, harmonious passion was also positively related to subjective well-being (SWB) in both studies, while obsessive passion was either unrelated (Study 1) or negatively related to SWB (Study 2). The conceptual and applied implications of the differential influences of harmonious and obsessive passion in performance are discussed.     

Testing assumptions of deliberate practice theory, relevance, effort, and inherent enjoyment of practice on a novel task

This study examined three assumptions of the theory of deliberate practice: that deliberate practice is perceived as relevant for improving performance and that it requires effort, but that it is not perceived as being inherently enjoyable. Of particular interest was the assumption of inherent enjoyment of practice since that has been questioned in previous research. 30 undergraduate and graduate students combined practiced a maze memorization and recall task and rated relevance of practice for improving recall, the practice effort, and inherent enjoyment of practice. The findings were consistent with three assumptions, but also suggested that perceptions about relevance, effort, and inherent enjoyment of practice may change with increasing experience and performance.     

Predicting performance times from deliberate practice hours for triathletes and swimmers: what, when, and where is practice important?

In Studies 1 and 2, the authors evaluated deliberate practice theory through analyses of the relationship between practice and performance for 2 populations of athletes: triathletes and swimmers, respectively. In Study 3, the authors obtained evaluations of practice from athletes' diaries. Across athletes, length of time involved in fitness activities was not related to performance. For the triathletes, a significant percentage of variance in performance was captured by practice. This was not so for sprint events for the swimmers, in which gender was a significant predictor. In the diaries, physical activities were perceived as enjoyable. In contrast to the results obtained from questionnaires, enjoyment did not covary with an activity's relevance to improving performance. Although these findings highlight the importance of sport-specific practice, the authors question a domain-independent account of expertise based on deliberate practice.     

The Socialization of Children’s Memory: Linking Maternal Conversational Style to the Development of Children’s Autobiographical and Deliberate Memory Skills

Data from a large-scale, longitudinal research study with an ethnically and socioeconomically diverse sample were utilized to explore linkages between maternal elaborative conversational style and the development of children’s autobiographical and deliberate memory. Assessments were made when the children were aged 3, 5, and 6 years old, and the results reveal concurrent and longitudinal linkages between maternal conversational style in a mother–child reminiscing task and children’s autobiographical memory performance. Maternal conversational style while reminiscing was also significantly related to children’s strategic behaviors and recall in 2 deliberate memory tasks, both concurrently and longitudinally. Results from this examination replicate and extend what is known about the linkages between maternal conversational style, children’s abilities to talk about previous experiences, and children’s deliberate memory skills as they transition from the preschool years to early elementary school years.     

Constant or variable practice: recreating the especial skill effect

An especial skill occurs when performance of a single action from within a class of actions produces an advantage in performance. This advantage in a single action over others in the class is presumed to result from large amounts of practice performing the specific action (Keetch, Schmidt, Lee, & Young, 2005). In an experiment involving the learning of a basketball set shot, practice was manipulated to identify whether an especial skill effect emerges at the free-throw line as a result of constant practice conditions in novice performers. After a pretest, which involved set shots across five distances, participants were randomly assigned to one of two intervention groups. A constant practice group (n=10) performed 300 trials of the set shot at the 15 ft free throw line only, whereas a variable practice group (n=10) performed 300 trials across five distances. Shot accuracy increased for both groups as a result of practice at the 15' distance. However, on the posttest, a significant difference was reported between actual and expected scores for the constant practice group only. This finding provided evidence that an effect similar to that seen for especial skills emerges as a result of constant practice. Although an especial skill effect could result from massive amounts of practice, we show it can emerge as a result of short term repetitive practice, indicating that the type, rather than amount, of practice is important.     

Young children's non‐numerical ordering ability at the start of formal education longitudinally predicts their symbolic number skills and academic achievement in maths

Ordinality is a fundamental feature of numbers and recent studies have highlighted the role that number ordering abilities play in mathematical development (e.g., Lyons et al., 2014 ), as well as mature mathematical performance (e.g., Lyons & Beilock, 2011 ). The current study tested the novel hypothesis that non‐numerical ordering ability, as measured by the ordering of familiar sequences of events, also plays an important role in maths development. Ninety children were tested in their first school year and 87 were followed up at the end of their second school year, to test the hypothesis that ordinal processing, including the ordering of non‐numerical materials, would be related to their maths skills both cross‐sectionally and longitudinally. The results confirmed this hypothesis. Ordinal processing measures were significantly related to maths both cross‐sectionally and longitudinally, and children's non‐numerical ordering ability in their first year of school (as measured by order judgements for everyday events and the parents’ report of their child's everyday ordering ability) was the strongest longitudinal predictor of maths one year later, when compared to several measures that are traditionally considered to be important predictors of early maths development. Children's everyday ordering ability, as reported by parents, also significantly predicted growth in formal maths ability between Year 1 and Year 2, although this was not the case for the event ordering task. The present study provides strong evidence that domain‐general ordering abilities play an important role in the development of children's maths skills at the beginning of formal education.     

Capturing naturally occurring superior performance in the laboratory: translational research on expert performance

One of the central challenges to studying highly skilled performance in the laboratory is methodological. It is necessary to develop standardized methods that allow investigators to make experts repeatedly reproduce their superior performance in the laboratory. The recent increase in demand for translational research has raised related issues of how everyday phenomena, such as successful clinical treatments and expert achievement, can be reproduced in the laboratory and how laboratory studies of these phenomena can lead to successful interventions in everyday life. The expert-performance approach was developed as a framework for capturing, analyzing, and accounting for complex acquired skills and adaptations. Performance is initially captured and elicited in the laboratory using tasks representative of core activities in the domain. Process-tracing measures are employed to identify the mechanisms that mediate the reproducibly superior performance. Finally, the factors responsible for the development of the mediating mechanisms are studied by a retrospective analysis of training activities, such as deliberate practice, as well as genetic prerequisites. The principles and mechanisms discovered need then be validated using more traditional longitudinal and experimental designs.
