Many learners in South Africa first encounter English when it is used as a medium of instruction at the start of formal schooling. This has ramifications for literacy acquisition and academic performance. Working memory is responsible for distributing cognitive resources among the various processing and storage tasks. It has been pivotal in many cognitive theories linking working memory to academic skills like reading comprehension and mathematics ability. In addition, research indicates that both Short Term Memory (STM) and Working Memory (WM) are instrumental in cognitive processing but that in bilinguals their roles are more complex than they are in monolinguals. This research explored the capacity of WM and the role of WM in reading comprehension and mathematical ability in two South African populations: a monolingual English group (L1) and a bilingual Afrikaans/English group (L2). No significant differences were found in the WM capacity of the two groups. In the second part of the study it was found that both reading comprehension and bilingualism depend on the same verbal domain resources of WM, which act as constraining factors for the L2 group. However, in the L1 group, there appeared to be less competition for verbal domain resources and more for visuospatial resources probably due to the phase of literacy acquisition these learners were in. In terms of WM and mathematical ability it was found that bilinguals exceed their storage capacity (STM) before they run out of processing capacity (WM). STM therefore is a constraining factor for this group. However, for the L1 group, visuospatial processing is the constraining factor. The research concludes that bilinguals use WM both for semantic processing of their nondominant language and for complex cognitive processing. While the WM capacity for monolingual and bilingual learners appears to be equivalent, the way the resources are allocated during cognitive tasks differ.

Dissertation Submitted to fulfil the requirements for the Degree of Master of Arts by Research (Psychology) by Dissertation Only / The aim of this study was to explore black South African women academics’ constructions of culture, mothering and education. The study further explored the relationships inherent between these aspects. The study followed a qualitative design through the utilisation of open-ended interviews that took place at a large urban public university in Johannesburg, South Africa. Nine women in academia who were linked predominantly to the field of health, who were of African descent and who had children between the ages of 0 and 18 years old were interviewed. The results illustrated that the women used multiple sources in the construction of their identities, some of which were congruent whereas between others there were tensions. The largest influence in their constructions of their identities was their religious affiliation, which took precedence over all other influences. At different stages of life their diverse identities held various significances to the women. This study is important because it is the first to investigate mothering in a low-risk African group

Rationale : Investigating the relationship between working memory and reading comprehension will lead to an improved understanding of the nature of working memory and will reveal how working memory contributes to reading comprehension failure. A pattern of working memory deficits will determine if ‘signature’ working memory profiles exist which will assist in the diagnosis and treatment of children with reading comprehension difficulties. Aims : (1) To explore the relationship between working memory and reading comprehension to determine if there are ‘signature’ working memory profiles that distinguish subgroups of Grade 5 English language learners with different comprehension capabilities. (2) To determine if a domain-specific or general working memory system is implicated in reading comprehension. (3) To explore the particular role played by the episodic buffer zone in reading comprehension. Method : Eighty Grade 5 English learners were tested on the GORT-4, AWMA and CELF- 4 Recalling Sentences Subtest. Based on their accuracy/decoding and comprehension scores on the GORT-4, participants were assigned to one of four reading ability groups: Skilled Reader Group; Reading Disabled Group; Poor Comprehender Group; or Poor Fluency Group. Comparison of mean standard scores determined how the four reading ability groups fared on the five memory components. Correlation and regression methods investigated the relationships between the five working memory variables and reading comprehension across the four reading ability groups. Results : Working memory plays a role in reading comprehension. The Skilled Reader group displayed intact working memory profiles, whilst the Reading Disabled group performed in the low average range on four working memory variables and below average on the fifth viz. sentence recall. The Poor Comprehender group’s working memory performance resembled that of the Skilled Reader group on two working memory variables. The Poor Fluency group performed below average on visuo-spatial short-term memory. These findings gave evidence of the inter-play between domain-specific and domain-general components of working memory during the complex task of reading comprehension. In addition, the findings highlighted the predictive role of sentence recall, as well as that of verbal working memory in reading comprehension. The episodic buffer was shown to play an important binding function between fluid and crystallised knowledge. The results suggested that reading comprehension was affected by a learner’s working memory capacity, however, working memory alone did not account for variations in performance. Lower-order and higher-order cognitive processes, as well as the interaction between fluid and crystallised knowledge appear essential to authentic reading. This has ramifications for prevention and remediation of reading comprehension deficits and underscores the important role of the speech therapist in literacy promotion.
