The Development of the Numeracy Apprehension Scale for Children Aged 4-7 Years: Qualitative Exploration of Associated Factors and Quantitative TestingPetronzi, Dominic; Staples, Paul; Sheffield, David; Hunt, Thomas E.; Fitton-Wilde, Sandra; University of Derby (2018-02-02)Previous psychological literature has shown mathematics anxiety in older populations to have an association with many factors, including an adverse effect on task performance. However, the origins of mathematics anxiety have, until recently, received limited attention. It is now accepted that this anxiety is rooted within the early educational years, but research has not explored the associated factors in the first formal years of schooling. Based on previous focus groups with children aged 4-7 years, ‘numeracy apprehension’ is suggested in this body of work, as the foundation phase of negative emotions and experiences, in which mathematics anxiety can develop. Building on this research, the first piece of research utilized 2 interviews and 5 focus groups to obtain insight from parents (n=7), teachers (n=9) and mathematics experts (n=2), to explore how children experience numeracy and their observations of children’s attitudes and responses. Thematic and content analysis uncovered a range of factors that characterised children’s numeracy experiences. These included: stigma and peer comparisons; the difficulty of numeracy and persistent failure; a low sense of ability; feelings of inadequacy; peer evaluation; transference of teacher anxieties; the right or wrong nature of numeracy; parental influences; dependence on peers; avoidance and children being aware of a hierarchy based on numeracy performance. Key themes reflected the focus group findings of children aged 4-7 years. This contributed to an item pool for study 2, to produce a first iteration of the Numeracy Apprehension Scale (NAS) that described day-to-day numeracy lesson situations. This 44-item measure was implemented with 307 children aged 4-7 years, across 4 schools in the U.K. Exploratory factor analysis led to a 26-item iteration of the NAS, with a 2-factor structure of Prospective Numeracy Task Apprehension and On-line Number Apprehension, which related to, for example, observation and evaluation anxiety, worry and teacher anxiety. The results suggested that mathematics anxiety may stem from the initial development of numeracy apprehension and is based on consistent negative experiences throughout an educational career. The 26-item iteration of the NAS was further validated in study 3 with 163 children aged 4-7 years, across 2 schools in the U.K. The construct validity of the scale was tested by comparing scale scores against numeracy performance on a numeracy task to determine whether a relationship between scale and numeracy task scores was evident. Exploratory factor analysis was again conducted and resulted in the current 19-item iteration of the NAS that related to a single factor of On-line Number Apprehension. This related to the experience of an entire numeracy lesson, from first walking in to completing a task and was associated with, for example, explaining an answer to the teacher, making mistakes and getting work wrong. A significant negative correlation was observed between the NAS and numeracy performance scores, suggesting that apprehensive children demonstrate a performance deficit early in education and that the NAS has the potential to be a reliable assessment of children’s numeracy apprehension. This empirical reinforces that the early years of education are the origins of mathematics anxiety, in the form of numeracy apprehension.
Epistemology, theory and Jung: Towards an analytical sport psychologySheffield, David; Cowen, Andrew; University of Derby (University of Derby, 2019-07-22)Sport psychology has historically adopted a positivist and post-positivist conceptualization of science at the expense of systematic engagement with epistemology itself (Whaley & Krane, 2011). In this thesis it will be argued that positivist orthodoxy does not hold a monopoly over the idea of science, and that future theoretical developments within sport psychology will require more systematic engagement with epistemology. In order to explore this proposition, the thesis examines the epistemology developed in C. G. Jung’s analytical psychology, an approach which has been generally overlooked within the sport psychology literature. In addition, more recent epistemological developments within psychology are considered with respect to current and future theorising within sport psychology. The thesis is a “desktop study” comprising of 8 chapters. The introduction (chapter 1) outlines how the current crisis within psychological science is epistemological, not methodological, in nature. Chapter 2 identifies key foundational challenges to sport psychology based on positivism; and introduces C. G. Jung’s analytical psychology which developed out of the rejection of a positivist conceptualization of science. Chapter 3 introduces aspects of a new epistemological framework (i.e., unconsciousness~consciousness; the psyche as a process) based on the work of Jung and identifies points of convergence between these contributions and more recent theorising. Chapter 4 considers the implications of analytical psychology with respect to momentum in sports. An original theoretical account of psychological momentum is outlined, based on libido theory (Jung, 1960), and the implications are considered with respect to current literature within sport psychology. Chapter 5 considers more recent developments in psychology (i.e., cybernetic systems paradigm, idiographic science) which have important parallels with analytical psychology, and which have important implications for the future of sport psychology as a science. Chapter 6 outlines an original theoretical perspective with respect to our understanding of performance variation in sport (Cowen, Nesti, & Cheetham, 2014), based on epistemological and theoretical developments outlined in the preceding chapters. Chapter 7 considers the implications of the epistemology outlined in the thesis with respect to current and future theorising in sport psychology. The central theme of this chapter is temporality, which, it is argued is necessarily an axiomatic component of future theoretical work, in order to overcome the foundational problems associated with a positivist conceptualisation of science. In the final concluding chapter (Chapter 8) it is proposed that the provisional epistemological criteria outlined in the thesis (i.e., subject~object, conceptual integration, being~becoming, teleology, temporality) offers a basis on which an analytical sport psychology could be developed. With respect to sport psychology, these criteria suggest that future developments should focus more on understanding performance variation itself rather than prioritising the study of psychological constructs, or objectivist representations, associated with performance. It is concluded that the “personal equation” – the creativity, judgement, intuition and/or insight of the researcher - represents an important component of the process of knowledge construction; which in turn necessitates collaboration as a necessary counterpoint to individual subjectivity. Taken together, this thesis suggests that analytical psychology, despite historically sitting outside of psychological science, can make an important contribution to the future of sport psychology as a scientific discipline.
The influence of caffeine expectancies on simulated soccer performance and perceptual statesHooton, Andy; Sheffield, David; Higgins, Matthew; Shabir, Akbar (University of DerbyThe University of Derby, School of Human Sciences, 2020-10)Caffeine (CAF) is the most widely consumed ergogenic substance in sport and has been reported to improve various attributes associated with successful soccer performance including, endurance capacity, gross motor skill performance and cognitions. These benefits are typically ascribed to pharmacological mechanisms (i.e. central nervous and peripheral tissue stimulation). However, the psychological and perceptual permutations that are associated with CAF expectancies are largely unaddressed in most experimental designs but could be as important as CAF pharmacology in understanding if/how CAF elicits an ergogenic response on sport performance. As the consumption of pharmacologically active CAF may not be necessary in observing a CAF associated ergogenic response, this body of work may prove beneficial to individuals suffering from pre-existing health concerns (e.g. hypertension, genetic polymorphisms, depression, insomnia etc.), CAF habituation, and those participating in late evening sports competitions whereby CAF consumption may impair sleep quality/duration. The main aim of this thesis is to evaluate and explore the psychobiological effects of expectancies associated with oral CAF consumption on various facets of simulated soccer performance and perceptual states. This was achieved via completion of the following objectives: (1) conducting a systematic review and meta-analyses pertaining to literature exploring the potential psychobiological effects of CAF on sport and exercise (A) and cognitive performance (B) (2) exploration of the potential psychobiological effects of CAF on high-intensity intermittent endurance capacity, reaction time and soccer skill proficiency (3) exploration of the potential psychobiological effects of CAF on perceptual fatigue and mood states (4) exploration of the potential psychobiological effects of CAF on subjective perceptions using the double-dissociation design but in particular the mixed methods approach (Brooks et al., 2015). There remains a severe under representation of the mixed methods design in the literature pertaining to the phenomenon of CAF expectancies on sport, exercise, and cognitive performance. The mixed methods design and associated triangulation of quantitative and qualitative data is fundamental to validly compare CAF’s psychological versus pharmacological impetus. Prior to this thesis, only two other studies (Beedie et al., 2006; Duncan et al., 2009) implemented the mixed methods design, with neither providing a rigorous account of methodological decisions, researcher reflexivity, and/or evidence of applying an epistemological framework. These factors were incorporated within the current thesis and improved the quality of data collection, analysis, and reflection. The results of our, novel, meta-analyses demonstrated that all studies exploring the psychobiological effects of CAF on sport and exercise performance displayed a beneficial effect (p=0.01) with an overall moderate effect size (Cohen’s d (ES): 0.40) observed. In contrast, no significant effect was observed for studies exploring the psychobiological effects of CAF on cognitive performance (p=0.142) with a small effect size (ES=0.1) observed. Though, due to significant methodological heterogeneity associated with studies exploring the psychobiological effects of CAF on cognitive performance, any associated implications here should be taken with caution. Experimental study 1 explored the influence of CAF expectancies on facets of simulated soccer performance (e.g. exercise capacity, reaction time and passing ability (LSPT)) and perceptual states via utilisation of a mixed-methods approach and double-dissociation design. Exercise capacity was greater (p<0.05) for CAF psychology (given placebo (PLA)/told CAF) (623 ± 117 s) versus pharmacology (given CAF/told PLA) (578 ± 99 s) with all participants running longer during psychology. This benefit appeared to be driven by CAF expectancies and reductions in perceptual effort. Interestingly, positive perceptions for told CAF conditions appeared to impair BATAK performance via potential CAF over reliance. In contrast, negative perceptions possibly facilitated BATAK performance via augmented conscious effort. A similar trend to BATAK was observed for LSPT performance. Following the completion of experimental study 1 it became apparent that the techniques used to modulate expectancies across experimental conditions (i.e. told PLA/CAF groups) here or any other study with a primary aim of exploring the influence of CAF expectancies on sport, exercise and/or cognitive performance, require validation. This was the premise of experimental study 2. No meaningful findings were observed from baseline to post-intervention across any outcome measure during experimental study 2. This lack of effect may be related to environmental factors, whereby individuals completed trials in classrooms and/or a home cinema, prior to lectures/seminars and/or social interactions, respectively. In contrast, participants in experimental study 1 were administered the appropriate expectancy modulating techniques after they had perceived to consume PLA or CAF within an environment that necessitated an immediate importance for CAF (e.g. prior to exercise performance). In summary, the novelty and original contribution of the current body of research entails: completion of a systematic review and meta-analyses pertaining to the influence of CAF expectancies on sport, exercise and cognitive performance; assessment of the influence CAF expectancies may have on simulated soccer performance; the implementation of a mixed methods approach and double dissociation design; an in depth rationale, description and set of instructions for the utilisation of the mixed methods approach in any future research, including the use of an epistemological framework; a summary of ecological factors that are fundamental in understanding the phenomenon of CAF expectancies across sport and exercise performance. With respect of the main findings from the experimental data contained in this thesis: the benefits associated with CAF expectancies may better suit tasks that entail lesser cognitive/skill specific attributes but greater gross motor function (e.g. cycling, weightlifting, running etc.) and this is likely due to reduced perceptual effort. Moreover, future studies aiming to validate expectancy modulating techniques or generally assessing expectancies should provide a greater immediate importance for CAF and this may be achieved by replicating environmental and/or psychosocial conditions associated with sport performance (e.g. the utilisation of a performance measure) and the perception for CAF consumption.
