We sought to replicate Ericsson, Krampe & Tesch-Römer's (Ericsson, Krampe & Tesch-Römer 1993 Psychol. Rev. 100 , 363–406) seminal study on deliberate practice. Ericsson et al . found that differences in retrospective estimates of accumulated amounts of deliberate practice corresponded to each skill level of student violinists. They concluded, ‘individual differences in ultimate performance can largely be accounted for by differential amounts of past and current levels of practice’ (p. 392). We reproduced the methodology with notable exceptions, namely (i) employing a double-blind procedure, (ii) conducting analyses better suited to the study design, and (iii) testing previously unanswered questions about teacher-designed practice—that is, we examined the way Ericsson et al . operationalized deliberate practice (practice alone), and their theoretical but previously unmeasured definition of deliberate practice (teacher-designed practice), and compared them. We did not replicate the core finding that accumulated amounts of deliberate practice corresponded to each skill level. Overall, the size of the effect was substantial, but considerably smaller than the original study's effect size. Teacher-designed practice was perceived as less relevant to improving performance on the violin than practice alone. Further, amount of teacher-designed practice did not account for more variance in performance than amount of practice alone. Implications for the deliberate practice theory are discussed.

The Relationship

This study used participants from the martial arts (karate) to examine the influence of context in the acquisition of novel motor sequences and the applicability of Ericsson, Krampe, and Tesch-Romer's (1993) theory of deliberate practice in this athletic domain. The presence of context did not benefit recall performance for the experts. The performance of the novice group was hindered by the presence of context. Evaluation of the role of deliberate practice in expert performance was assessed through retrospective questionnaires. The findings related to the relationship between relevance and effort, and relevance and enjoyment diverged from Ericsson et al.'s (1993) definition of deliberate practice, suggesting that adaptations should be made if it is to be considered general theory of expertise.

Paradigm Function Morphology (PFM) is an evolving approach to modeling morphological systems in a precise and enlightening way. The fundamental insight of PFM is that words have both content and form and that in the context of an appropriately organized lexicon, a language’s morphology deduces a complex word’s form from its content. PFM is therefore a realizational theory: a language’s grammar and lexicon are assumed to provide a precise characterization of a word’s content, from which the language’s morphology then projects the corresponding form. Morphemes per se have no role in this theory; by contrast, paradigms have the essential role of defining the content that is realized by a language’s morphology. At the core of PFM is the notion of a paradigm function, a formal representation of the relation between a word’s content and its form; the definition of a language’s paradigm function is therefore the definition of its inflectional morphology. Recent elaborations of this idea assume a distinction between content paradigms and form paradigms, which makes it possible to account for a fact that is otherwise irreconcilable with current morphological theory—the fact that the set of morphosyntactic properties that determines a word’s syntax and semantics often differs from the set of properties (some of them morphomic) that determines a word’s inflectional form. Another recent innovation is the assumption that affixes and rules of morphology may be complex in the sense that they may be factored into smaller affixes and rules; the evidence favoring this assumption is manifold.

Experiential factors such as long-term deliberate practice are powerful and necessary conditions for outstanding achievement. Nevertheless, to be able to reject the role of biology based individual differences (including genetic ones) in the manifestation of talent requires designs that expose heterogeneous samples to so-called testing-the-limits conditions, allowing asymptotic levels of performance to be analyzed comparatively. When such research has been conducted, as in the field of lifespan cognition, individual differences, including biology based ones, come to the fore and demonstrate that the orchestration of excellence requires joint attention to genetic–biological and experiential factors.

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.

The profession of explainer is still pretty much undefined and underrated and the training of explainers is many times deemed to be a luxury. In the following pages we make the argument that three main factors contribute to this state of affairs and, at the same time, we try to show why the training of explainers should really be at the core of any science communication institution. These factors are: an erroneous perception of what a proper scientific training means for explainers; a lack of clear definition of the aptitudes and role of explainers required by institutions that are evolving and diversifying their missions; and an organizational model based on top-down practices of management and activity development which underappreciates the potential of the personnel working directly with the public.

Maladaptive risk taking can have severe individual and societal consequences, thus individual differences are prominent targets for intervention and prevention. How to capture individual differences in risk taking, however, presents a major challenge because convergence between measures is mostly low. Considering that functional brain markers are being examined for their potential to account for various risk-taking related outcomes, we urgently need to establish the role of risk-taking measures for establishing reliable brain-outcome associations. To address this issue, we analyzed within-participant neuroimaging data for two widely used risk-taking measures collected from the imaging subsample of the Basel–Berlin Risk Study (N = 116 young human adults), and computed brain-outcome associations within/out-of-measure as well as within/out-of-session. Although we observed a regionally-specific convergence of group-level activation differences for the two imaging measures in the nucleus accumbens, one of the core brain regions associated with risk taking, results from our individual differences analyses suggest that (1) individual differences in brain activation are not preserved between measures, and (2) the success of brain-outcome associations for risk taking is highly dependent on the measures used to capture neural and behavioral individual differences. Our results help to better filter risk- taking measures for their potential to establish brain markers for intervention or prevention purposes.

Chapter 6 explores the central concept of ‘investment’. It first considers the core question of the definition of ‘investment’ under the ICSID Convention and under investment treaties. It then takes up four important issues: (1) the time when an investment is made in relation to the temporal scope of the treaty protections; (2) the extent to which pre-contract investment may obtain treaty protection; (3) the place of an investment; and (4) the role of host State law in defining ‘investment’. It then analyses a set of problems that arise out of indirect investments: the relation between the losses suffered by a subsidiary in the host State and the investor’s investment; the rights of minority shareholders; claims brought by holding companies; corporate restructuring as a means to gain the advantage of investment treaties; the position of ultimate beneficiaries; and the position of portfolio investments.

OBJECTIVE: To determine the role of inhaled corticosteroids in the treatment of mild chronic asthma. SOURCE OF STUDIES: Searches of MEDLINE and Index Medicus for English language literature dealing with asthma and inhaled corticosteroids. DESIGN: All retrieved articles were subjected to predetermined criteria for inclusion in the meta-analysis. Inclusion criteria centered around randomized, double-blind studies reporting objective clinical endpoint(s) for subjects with mild chronic asthma who were treated for more than seven days. Studies that were included were not allowed to have any predetermined exclusion criteria. RESULTS: The literature search identified 129 articles, of which 41 satisfied some but not all of the criteria for inclusion. Five articles met all the criteria and were subjected to meta-analysis. The total number of subjects was 141. Peak expiratory flow rate (PEFR) was used as the objective endpoint for effect size calculation. Subjecting these five studies to quality review revealed a range of 0.607–0.741, with 1 as the highest attainable quality and 0 the lowest. Reported results for the different studies were found to be homogenous, thus allowing for the calculation of overall effect size. Inclusion of children in some of the studies added variance to the reported studies, but not to the point at which studies would be considered heterogenous. Effect sizes ranged between 0.41 and 0.89, and the overall weighted average effect size for PEFR was 0.59, with the calculated 95 percent confidence interval at 0.32 to 0.84. A tabulated display of binomial effect size for included trials provided ranges of success rates for treatment versus control values. Results of the studies were judged robust, as 92 studies reporting no significant effects are needed to turn the finding of the meta-analysis insignificant. CONCLUSIONS: Based on the results of the meta-analysis, the existing literature suggests a role for inhaled corticosteroids in the treatment of mild chronic asthma.

Suggestions that psychology lacks academic substance are common. Recently, in an article in the Australian newspaper, Emeritus Professor John Sutcliffe described it as a “dicky-shirt” discipline -- all form and no substance (Sutcliffe, 1994). He wrapped his observation into a general attack on the Dawkins education reforms which he correctly blames for eroding the intellectual core of Australian academic life. Many academics share Sutcliffe's concerns.The Dawkins reforms are an uneasy blend of populism and commercialism aimed at achieving the Labour government's economic goal of a “clever country”. Most conspicuously, they have involved the incorporation of former technical institutes into large multi-campus universities. The result has been the physical extension of a university presence across the country into some improbable rural backwaters. Inevitably these dramatic changes in the size and spread of universities have been accompanied by a change in the definition of the role of universities. Topics of study which were once the domain of lower tier tertiary institutions now find a place in the core academic centres. The result has been a shift in the balance of academic interest from abstract to applied research and teaching.Feeding into these changes has been what Sutcliffe describes as a “money-driven” ethos. After decades of intervention to redress inequalities and irrationalities stemming from the operation of free markets, Labour governments in various parts of the West have capitulated to historical forces and pre-emptively embraced the free enterprise policies of the traditional right.

The Relationship

The relationship between consciousness and working memory (WM) has been recently debated both at the theoretical and methodological levels (Persuh et al., 2018; Velichkovsky, 2017). While there is behavioral and neural evidence that argues for the existence of unconscious WM, several methodological concerns have been raised, rendering this issue highly controversial. To address the robustness of the previous findings, here we adopt a meta-analytic approach to estimate the effect size and heterogeneity of the previously reported unconscious WM results, also including unpublished results. We used meta-regression to isolate relevant experimental variables, in particular, consciousness manipulation and WM paradigm to identify the source of the heterogeneity in the reported effect size of the unconscious WM. Our meta-analysis supports the existence of the unconscious WM effect and critically reveals several experimental variables that contribute to relevant heterogeneity. Our analysis clarifies several theoretical and methodological issues. We recommend that future studies explicitly operationalize the definition of consciousness, standardize the methodology and systematically explore the role of critical variables for the unconscious WM effect.
