Instrumental vision

This chapter interrogates stereo-immersive ‘virtual reality’ (VR), the technology that enables a perceiver to experience what it is like to be immersed in a simulated environment. While the simulation is powered by the “geometry engine” (Cutting, 1997: 31) associated with high-end computer imaging technology, the visual experience itself is powered by ordinary human vision: the vision system’s innate capacity to see “in 3D”. To understand and critically appraise stereo-immersive VR, we should study not its purported ‘virtuality’, but its specific visuality, because the ‘reality’ of a so-called ‘virtual environment’ is afforded by the stereoacuity of binocular vision itself. By way of such a critique of the visuality of stereo-immersive VR, this chapter suggests that we think about the ‘practice’ of vision, and consider on what basis vision can have its own ‘materiality’. Pictorial perception is proposed as an exemplary visual mode in which the possibilities of perception might emerge. Against the ‘possibilities’ of vision associated with pictures, the visuality of stereo-immersive VR emerges as a harnessing, or ‘instrumentalisation’ of vision’s innate capabilities. James J. Gibson’s ‘ecological’ approach to vision studies is referenced to show the degree to which developers of VR have sought — and succeeded — to mimic the ‘realness’ of ordinary perceptual reality. This raises a question concerning whether the success of stereo-immersive VR is simultaneously the source of its own perceptual redundancy: for to bring into being the perceptual basis of ordinary ‘real’ reality, is to return the perceiver to what is already familiar and known.

Adaptive autobiographical memory in younger and older adults : the indirect association of integrative and instrumental reminiscence with depressive symptoms

Despite the established effectiveness of reminiscence-based interventions for depression, little research exists into the pathways through which specific reminiscence functions are related to depressive symptoms. Drawing on theory of the mechanisms of change in cognitive-reminiscence therapy, the current study tests the hypothesised indirect associations of adaptive integrative and instrumental reminiscence functions with depressive symptoms and whether these relationships might differ among younger and older adults. Questionnaires were completed by a large community sample of the Australian population. Multiple mediation models were tested in two groups: younger adults (n=730, M age=52.24, SD=9.84) and older adults (n=725, M age= 73.59, SD=6.29). Results were consistent across age groups, indicating that there was direct relationship between these reminiscence functions and depressive symptoms, but that integrative reminiscence is indirectly associated with depressive symptoms through meaning in life, self-esteem, and optimism, and that instrumental reminiscence is indirectly associated with depressive symptoms through primary control and self-efficacy. This study provides support for the relationships between constructs underlying the proposed mechanisms of change in cognitive-reminiscence therapy for the treatment of depression, and suggests these relationships are similar for younger and older adults.

Relationships between wearer assessment and the instrumental measurement of the handle and prickle of knitted wool fabrics

The relationships between wearer-assessed comfort and objectively measured comfort and handle parameters were investigated using 19 pure wool single jersey garments made of single ply yarns. Wearer trials were used to determine prickle discomfort, and whether wearers “liked” the garments. Fabrics then were objectively evaluated using the Wool HandleMeter, which measures seven primary handle attributes; and the Wool ComfortMeter (WCM), to predict a wearer's perception of fabric-evoked prickle. Wearer responses and the relationships within and between objective measurements and the effect of fibre, yarn and fabrics attributes were analysed by general linear modelling. Mean fibre diameter, fibre diameter coefficient of variation, yarn count, fabric thickness, fabric density, fabric mass per unit area and decatising affected one or more handle parameters. The best model for predicting wearer prickle discomfort accounted for 90.9% of the variance and included only terms for the WCM and WCM2. The WCM was a good predictor whereas mean fibre diameter was a poor predictor of whether wearers “liked” garments. Wearer assessment of prickle and whether or not wearers “liked” fabrics were independent of fabric handle assessment. The results indicate that the handle and comfort properties of lightweight, wool jersey fabrics can be quantified accurately using the Wool HandleMeter and the Wool ComfortMeter. For fabric handle, fibre and yarn characteristics were less important than changes in the properties of the fabric.
