Discourse analysis is a useful and flexible method for exploring power and identity. While there are many forms of discourse analysis, all agree that discourse is the central site of identity construction. However, recent feminist concerns over power, agency, and resistance have drawn attention to the absence of participants’ first-hand experiences within broad discursive accounts (Lafrance &; McKenzie-Mohr 2014; Saukko 2008). For those with an interest in power relations, such as feminist researchers, this is a problematic silence which renders the personal functions of discourse invisible. In this article, we argue that the “personal” and “political” are inextricable, and we make a case for putting the “personal” into broader discursive frameworks of understanding. Further, we assert that feminist research seeking to account for identity must more explicitly aim to capture this interplay. To this end, we argue that voice is the key site of meaning where this interplay can be captured, but that no clear analytical framework currently exists for producing such an account. In response, we propose Feminist Relational Discourse Analysis (FRDA) as a voice-centered analytical approach for engaging with experience and discourse in talk. We then set out clear guidance on how to do FRDA, as applied in the context of women working in U.K. policing. Finally, we conclude that by prioritizing voice, FRDA invites new and politicized feminist readings of power, agency, and resistance, where the voices of participants remain central to the discursive accounts of researchers. 相似文献

This study investigated retrieval mechanisms that may be involved in memory for distressing stimuli. Forty-one nonclinical participants watched a video clip depicting the immediate aftermath of a serious car accident. Following this, half of the participants were instructed to focus attention on the victims of the accident and to consider the negative sequelae of their injuries. The remaining participants were not given any instructions. Following the Victim Focus/Control period, all participants completed a cued-recall task assessing their memory of the video clip. Overall, victim-related details were better recalled than nonvictim related details. It is important to note that participants in the Victim Focus condition retrieved fewer peripheral details than participants in the Control condition. These results suggest that people focusing attention on distressing aspects of an event can experience a cost in remembering other aspects of the event. These findings may be interpreted in terms of enhanced recollection of central events or retrieval-induced forgetting mechanisms to explain patterns of diminished memory for aspects of distressing events. 相似文献

This paper reviews the effects of single and repetitive transcranial magnetic stimuli (rTMS) delivered to one cortical area and measured across distributed brain regions using electrophysiological measures (e.g. motor thresholds, motor evoked potentials, paired-pulse stimulation), functional neuroimaging (including EEG, PET and fMRI) and behavioural measures. Discussion is restricted to changes in excitability in the primary motor cortex and behaviour during motor tasks following transcranial magnetic stimulation delivered to primary motor and premotor areas. Trains of rTMS have lasting effects on the excitability of intrinsic and corticofugal neurones, altering the responsiveness of local and remote sites. These effects lead to distributed changes in synaptic activity at rest, and during a range of motor tasks. It is possible to impair or improve performance following rTMS, but for most simple motor tasks performance is unaltered. Changes in distributed activity observed with functional imaging during motor behaviour may represent compensatory activity, enabling maintenance of performance; stimulation of additional cortical areas appears to impair performance. A detailed understanding of the distributed changes in excitability following rTMS may facilitate future attempts to modulate motor behaviour in the healthy brain and for therapeutic purposes. 相似文献

In this study, we examined the effect of within-category diversity on people's ability to learn perceptual categories, their inclination to generalize categories to novel items, and their ability to distinguish new items from old. After learning to distinguish a control category from an experimental category that was either clustered or diverse, participants performed a test of category generalization or old-new recognition. Diversity made learning more difficult, increased generalization to novel items outside the range of training items, and made it difficult to distinguish such novel items from familiar ones. Regression analyses using the generalized context model suggested that the results could be explained in terms of similarities between old and new items combined with a rescaling of the similarity space that varied according to the diversity of the training items. Participants who learned the diverse category were less sensitive to psychological distance than were the participants who learned a more clustered category. 相似文献

The effect of long-term knowledge upon performance in short-term memory tasks was examined for children from 5 to 10 years of age. The emergence of a lexicality effect, in which familiar words were recalled more accurately than unfamiliar words, was found to depend upon the nature of the memory task. Lexicality effects were interpreted as reflecting the use of redintegration, or reconstruction processes, in short-term memory. Redintegration increased with age for tasks requiring spoken item recall and decreased with age when position information but not naming was required. In a second experiment, redintegration was found in a recognition task when some of the foils rhymed with the target. Older children were able to profit from a rhyming foil, whereas younger children were confused by it, suggesting that the older children make use of sublexical phonological information in reconstructing the target. It was proposed that redintegrative processes in their mature form support the reconstruction of detailed phonological knowledge of words. 相似文献

Similarity as transformation 总被引:2,自引:0,他引:2
We propose that similarity is determined by the transformation distance between representations: entities which are perceived to be similar have representations which are readily transformed into one another, whereas transforming between dissimilar entities requires many transformations. We present three experiments that indicate that similarity is strongly influenced by transformation distance. These data present a challenge for featural or spatial accounts of similarity. Finally, we introduce a family of transformation-based accounts of similarity, called 'Representational Distortion', as a specific example of a transformational approach to similarity. 相似文献

Three experiments were conducted to examine the effects of extraneous speech warnings (i.e., low-priority warnings initiated during high-priority tasks) on cognitive performance and whether organizing the auditory warnings into streams can attenuate any disruption. Experiment 1 demonstrated that a variety of speech warnings can be separated into perceptually distinct streams by allocating them to discrete spatial locations. Experiment 2 showed that increasing the rate of presentation of the warnings to promote streaming decreased clarity ratings but increased perceived urgency ratings. Experiment 3 demonstrated that the disruption to serial memory for navigational information by extraneous speech warnings could be attenuated by streaming. Results are interpreted in light of previous research, and practical implications for auditory warning design are discussed. 相似文献

The pattern of language deficit following left-hemisphere brain injury and visual/spatial deficit following right-hemisphere injury in an adult or older child is well recognized, but has been inconsistently reported following presumed neonatal brain injury. Our prospective study of 24 children at age 5 with documented neonatal unilateral brain injury lends support to the theory of hemisphere specialization at the time of birth. Twelve children who had unilateral left-hemisphere lesion were compared to 12 children with unilateral right-hemisphere lesion of similar timing and severity. Relative visual/spatial deficit following right-hemisphere lesion and receptive language deficit following left-hemisphere lesion were identified. Lateralized measures of grip strength, fine motor speed, and fine motor dexterity were not significantly different between the groups for either hand in this nonhemiparetic study sample. Only one child with a left-hemisphere lesion was left-handed, and only one child (right-lesion) had a hemiparesis. 相似文献
