- Description: Statistics anxiety describes the extensive worry and apprehension that students may experience when faced with statistics content as part of their university curriculums. Student’s perfunctory disposition towards statistics has been indicated to negatively affect performance outcomes in statistics courses. Two meta-analyses were conducted to investigate the relationship between statistics anxiety and achievement in statistics. The first meta-analysis was inclusive of 22 studies investigating the relationship attitudes towards statistics and achievement, whilst the second meta-analysis focused on the relationship, primary amongst Psychology students. Student’s attitudes towards statistics were measured using the Survey of Attitudes Towards Statistics (SATS), whilst achievement in statistics courses was quantified using different outcome measures. Finding from the meta-analysis were supplemented by cortical mapping of the neural correlates of statistical reasoning using functional near-infrared spectroscopy (fNIRS). Results from the meta-analysis indicated a small significant relationship between university students’ Affect, r = 0.28, Value, r = 0.22 and Difficulty, r = 0.18, and subsequent achievement in statistics courses. A medium significant relationship between Cognitive Competence, r = 0.31, and achievement was also noted. Findings from the second meta-analysis, indicated a medium, significant relationship between Affect, r = 0.32, and Cognitive Competence, r = 0.35, and achievement. Moreover, a small significant relationship was found between Value, r = 0.24, and Difficulty, r = 0.23, in relation to achievement in statistics courses. Case study analysis of the neural correlates of statistics reasoning revealed varied signal quality findings of cortical mapping of the neural correlates of statistics in the dorsolateral prefrontal cortex (DLPFC). Moreover, seed-based correlation analysis indicated cortical activation of the dorsolateral prefrontal cortex paired with diverse prefrontal regions. Recommendations from the study include improvements to the fNIRS research design and the inclusion of larger samples to investigate the cortical mapping of the DLPFC in relation to statistics reasoning and statistics anxiety. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024

- Description: Deficits in sustained attention are ubiquitous across numerous neuropsychological disorders. Besides being critical in learning, memory, and general cognitive capacity, sustained attention is thought to be the primary foundation for ‘higher’ cognitive functions including, divided, selective, and focused attention. Despite the above, sustained attention remains the lesser-researched form of attention. Sustained attention is thought to be regulated by the default mode network and the central executive network, the latter of which is situated in the dorsolateral prefrontal cortex (DLPFC), a brain region typically associated with sustained attention. Given the contributions of sustained attention in overall cognitive functioning, alternative and natural methods used to enhance this type of executive function are important. One alternative method is yoga exercise, where yoga is thought to place the body into the most favourable state to enhance sustained attention capacity. This study found a significant (p = 0.018) difference between the yoga and control group in incongruent response accuracy scores in the SCWT. However, no statistically significant differences (p < 0.05) were observed in fNIRS individual and group analyses, SCWT congruent and incongruent reaction time, as well as congruent response accuracy. This suggests that short-term yoga practice may improve behavioural markers for sustained attention, at least in terms of cognitive interference. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024
