Drawing upon a concept of ‘critical bioethics’ [7] this paper takes a species-broad approach to the social and ethical aspects of enhancement. Critical Bioethics aims to foreground
interdisciplinarity, socio-political dimensions, as well as reflexivity to what becomes bioethical subject matter. This paper
focuses upon the latter component and uses the example of animal enhancement as a way to think about both enhancement generally,
and bioethics. It constructs several arguments for including animal enhancement as a part of enhancement debates, and considers
some connections between human and animal enhancement. The paper concludes in a plea for an ‘enhancement’ to our critical
abilities to examine some of the underlying social, moral and ethical assumptions bound up in varied anticipated ‘enhanced’
futures.

Executive function is foundational for cognitive development. Previous research has shown both gross motor skills and physical activity to be related to executive function. However, evidence for these relationships in the preschool years, as well as in low‐ and middle‐income countries is lacking. Therefore, this study aimed to investigate the relationships between components of executive function (inhibition, shifting and working memory) and gross motor skills (locomotor skills and object control skills) in a sample of preschool children from urban and rural low‐income settings in South Africa. Results revealed that inhibition and working memory, but not shifting, were associated with gross motor skills. More specifically: inhibition was associated with both locomotor [β = 0.20, p = 0.047] and object control skills [β = 0.24, p = 0.024], whereas working memory was only associated with locomotor skills [β = 0.21, p = 0.039]. Physical activity was not associated with inhibition and shifting but was negatively associated with working memory. These results elaborate a growing evidence base linking executive function and gross motor skills in the early years, and it is the first to look at specific associations of locomotor and object control skills with executive function in the South African context (a low‐ and middle‐income country). 相似文献

The widely and internationally replicated socioeconomic status (SES) gradient of executive function (EF) implies that intervention approaches may do well to extrapolate conditions and practices from contexts that generate better child outcomes (in this case, higher SES circumstances) and translate these to contexts with comparatively poorer outcomes (often low‐SES populations). Yet, can the reverse also be true? Using data from equivalent assessments of 1,092 pre‐schoolers’ EFs in South Africa and Australia, we evaluated: the SES gradient of EF within each sample; and whether this SES gradient extended cross‐culturally. The oft‐found EF‐SES gradients were replicated in both samples. However, contrary to the inferences of EF‐SES associations found nationally, the most highly disadvantaged South African subsample outperformed middle‐ and high‐SES Australian pre‐schoolers on two of three EFs. This suggests the possibility of EF‐protective and ‐promotive practices within low‐ and middle‐income countries that may aid understandings of the nature and promotion of EFs. 相似文献

This article reports on research on antecedents of first-year male students’ experiences of senior male students’ aggression in residences at a university in South Africa. Fourteen purposefully selected first-year male student residents (black = 14%; coloured = 7%; white = 79%) voluntarily participated. Their ages ranged between 18 and 21 years. Data were on their perceived precursors to aggression and violence that were collected using photo-narratives (written) and photo-narrative-elicitation-interviews. The data were analysed by means of Interpretative Phenomenological Analysis (IPA). Three themes emerged which indicate that precursors to aggression and violence included physical and verbal aggression in the form of hitting, shoving around, pushing and shouting, swearing, taunting others, and nasty comments. Social aggression involves acts of bullying, exertion of power, modelling dominant behaviour in which perpetrators defend their status, or signal exclusion of others. The survivors experienced pressure to conform to fellow residents’ practices, norms and behaviour in the hope that they would gain acceptance into the in-group. 相似文献

The recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions (Experiment 1) as well as differently-valenced emotions (Experiment 2) conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence for a context effect on accuracy only in Experiment 1. This demonstrates that affective theory of mind inferences made at the pragmatic level of a text can automatically, contextually influence the perceptual processing of emotional facial expressions in a separate task even when those emotions are of a distinctive valence. Thus, our novel findings suggest that language acts as a contextual influence to the recognition of emotional facial expressions for both same and different valences. 相似文献

False recognition in children aged 5, 8, and 11 years was investigated using the standard version of the Deese-Roediger-McDermott (DRM) procedure and an alternative version in which the DRM stimuli were embedded in stories designed to emphasize their overall theme. Relative to the 8- and 11-year-olds, the 5-year-olds falsely recognized fewer critical lures when the DRM stimuli were presented in lists, but falsely recognized more critical lures when the stimuli were presented in stories. Levels of false recognition in the 8- and 11-year-olds were not affected by study format. We argue that the story context enhanced the ability of the 5-year-olds to make inferences based on the theme of the DRM stimuli. The 5-year-olds then showed higher levels of false recognition than the older children owing to their inability to reject lure words consistent with the stories. 相似文献
