Media coverage of ‘decades of disparity’ in ethnic mortality in Aotearoa

For some time we have known that factors such as economic prosperity, community cohesion, and social justice bear on health. These societal influences are particularly pertinent to the health of indigenous groups, such as Maori, who are still responding to processes of colonization. In July 2003 the New Zealand Ministry of Health published a report entitled ‘Decades of Disparity’, which proposed (among other things) that neoliberal policies of the last two decades impacted negatively on mortality rates for Maori and Pacific peoples, when compared with Pakeha. In this article we explore media coverage of this report through analyses of media releases, radio, television and newspaper items. It is argued that as the story evolved media increasingly challenged the importance of societal determinants of health, preferring individual level explanations. As a result coverage failed to give due emphasis to structural health concerns for Maori, which necessitate social change. Copyright © 2004 John Wiley & Sons, Ltd.     

Narrating the negative consequences of elder care and familial obligation in Atlantic Canada

At a time when renewed emphasis is being placed on the role of the family in providing care for elderly people, shifts in family structures and the demographic profile of societies such as Atlantic Canada are impacting on community structures foundational to familial caregiving practices. Research shows that family members who attempt to provide familial care without adequate support risk negative health and interpersonal consequences. Hence many find it necessary to reflect upon their familial obligations. This article investigates the storytelling processes through which caregivers, aged between 45 and 55 years (N = 26), make sense of their efforts to provide care. We explore the ways in which participants in four focus groups and 12 interviews refer to negative consequences of caring in order to navigate dilemmas arising from their enactment of familial obligations in the absence of adequate support.

The Sound of Silence: Can Imagining Music Improve Spatial Rotation Performance?

We report two experiments exploring whether imagining music improves spatial rotation via increases in arousal and mood levels (Schellenberg 2005). To aid their imagination, participants were given instructions (none, basic or detailed) and lyrics (present or absent). Experiment 1 showed no effect of instructions or lyrics on performance although participants felt that the presence of the lyrics helped. Experiment 2 was identical to Experiment 1 except that the participants were musicians (as evidenced by musical experience and/or qualification). This time there was a significant effect of instructions in that those who received the detailed instructions performed significantly better than the no instruction condition although the presence of lyrics did not help. Further research is required to establish the similarity of the imagination to the traditional arousal and mood effect but the phenomenon may be useful for short-term boosts in spatial rotation activities.     

Similarity-based asymmetries in perceptual matching

Asymmetries, where response times differ depending on the order of two stimuli, have been widely used to explore fundamental aspects of perceptual processing. Given how much is made of asymmetries in the study of perception there has been surprisingly little research into the cognitive mechanisms that may underlie why comparing two objects in isolation depends on the order of presentation. In visual search, for example, asymmetries are typically attributed to fundamental processing characteristics as opposed to the inherent relation between two stimuli. However, one possible explanation for asymmetries found in perceptual processing is that similarity is important in the task and it is similarity itself that is asymmetric. In the current paper, we use a stimulus set for which the transformational account of similarity predicts asymmetries based on differences in transformational complexity. Using the fine-grained measure of reaction time we show that directional differences in transformation distance successfully predict asymmetries in the speed of matching two stimuli in sequence. The results are discussed in relation to the role of transformations in perceptual identification more generally, and how transformations could be revealing about how objects are compared in other experimental contexts where objects are compared directionally (e.g., visual search).     

Disruption of verbal-spatial serial memory by extraneous air-traffic speech

The disruptive impact of task-extraneous air-traffic radio speech on a task involving the serial-recall of combined verbal and spatial stimuli (7 letters and their locations) that were broadly analogous to information about aircraft callsigns and movements was examined. Regardless of the dimension to be recalled (identity or spatial location), accuracy was significantly disrupted by the air-traffic speech. Prior knowledge as to which dimension to recall did not affect accuracy and did not interact with the disruptive effect of air-traffic speech, but did extend the time to initiate a response to the first item. The results are discussed with reference to theories of the irrelevant sound effect and stimulus-dimension binding in short-term memory. The vulnerability of cognitive processing related to air-traffic management and similar work environments is also discussed.
