Black feminist intellectual activism: a transformative pedagogy at a South African university

This dissertation engages with critical pedagogic theories and activism from a black feminist perspective. The central argument is that education is not only confined to the formal classroom but also takes place in the most unlikely places outside the classroom. This work is premised on the educational philosophies of liberation, embodiment and freedom of the oppressed and the marginalised. The qualitative research is largely presented as ethnographical research, with the researcher located as both participant in the evolvement of the two educational programmes and as writer of this dissertation. Both educational programmes deal with performance and performativity and aim to give voice to the marginalised bodies and lives in the university environment. The research demonstrates how two marginalised groups claim space on campus through performativity involving the body and voice. In the Edudrama, Reclaiming the P…Word, young black women, via representation of word and body, transform the performance space into one in which the misogynistic and racist gaze is transformed. This feminist theatre is intrinsically related to the feminist political work of reclamation of the black female body, which became invisible and objectified for abuse under colonialism, apartheid and patriarchy. The various feminist elements and processes involved in creating feminist text and theatre are discussed. The praxis involved in these processes is then theorised in terms of critical pedagogy as black feminist intellectual activism. In the case of the lesbian, gay and transgender programme, Loud Enuf, the bodies and voices are used differently in the public campus domain to challenge homophobia. This programme is used to raise awareness about sex, sexuality, sexual orientation and gender identity. This programme is intensely political and challenges ambiguous understandings regarding the notion of equality in South Africa post-1994

Liar liar neurons fire: how executive control processes contribute to the ability to deceive

This thesis presents a series of empirical investigations into the executive demands of deception. The first two experiments investigated whether the executive demands of deception are sufficient to influence receiver perceptions of credibility. Participant-senders in Study 1 (n = 52) and Study 2 (n = 97) completed a false opinion task and a battery of cognitive tasks. Deception performance was operationalized via participant-receiver judgements of veracity (Study 1, n = 624; Study 2, n = 1140). While the results from Study 1 showed a small positive relationship between executive abilities and deception performance, the results from Study 2 were stronger. They indicated that while working memory skill had a moderate positive relationship with deception performance, set shifting and inhibitory control skills were unrelated to deception performance once working memory skill had been taken into account. The third study used a resource depletion framework to experimentally manipulate executive abilities. Participant-senders (n = 114) completed two false opinion tasks; one before the administration of a cognitive task (either an executive task designed to deplete the availability of executive resources or one of two control tasks) and the other immediately after. Once again deception performance was operationalized via participant-receiver judgements of veracity (n = 798). The results indicated that while deception performance was impaired by the executive task, it was relatively unaffected by either of the control tasks. The fourth study presents a theoretical analysis assessing the appropriateness of standard by-judge and by-sender aggregating procedures commonly used in deception detection research. A series of Monte Carlo simulations demonstrated that the aggregation of deception data can cause inflated Type 1 error rates and poor statistical power and that Generalized Linear Mixed Models (GLMMs) may overcome these problems. Consequently, a series of GLMMs were used to re-analyze the data from Study 3. The results were consistent with previous analyses. Overall, the evidence reported in this thesis demonstrates that the demands of deceiving in false opinion tasks are sufficient to influence a person’s behaviours such that those with poor executive abilities tend to be worse liars than those with good executive abilities
