Narrative Personae and Visual Signs: Reading Leonard’s intimate photo-memoir. a/b: Auto/Biography Studies.

: In this paper, I look at Joanne Leonard’s Being in Pictures and engage in a critical dialogue with an assemblage of visual and textual narratives that comprise her intimate photo memoir. In doing this I draw on Hannah Arendt’s take on narratives as tangible traces of uniqueness and plurality, political traits par excellence in the cultural histories of the human condition. Being aware of my role as a reader/viewer/interpreter of a woman artist’s auto/biographical narratives, I move beyond dilemmas of representation or questions of unveiling “the real Leonard”. The artist is instead configured as a narrative persona, whose narratives respond to three interrelated themes of inquiry, namely the visualization of spatial technologies, vulnerability and the gendering of memory. Key words: gendered memories, narrative persona, spatial technologies, photo memoir, vulnerability

Vestibular and oculomotor influences on visual dependency

The degree to which a person relies on visual stimuli for spatial orientation is termed visual dependency (VD). VD is considered a perceptual trait or cognitive style influenced by psychological factors and mediated by central re-weighting of the sensory inputs involved in spatial orientation. VD is often measured using the rod-and-disk test, wherein participants align a central rod to the subjective visual vertical (SVV) in the presence of a background that is either stationary or rotating around the line of sight - dynamic SVV. Although this task has been employed to assess VD in health and vestibular disease, it is unknown what effect torsional nystagmic eye movements may have on individual performance. Using caloric ear irrigation, 3D video-oculography and the rod-and-disk test, we show that caloric torsional nystagmus modulates measures of visual dependency and demonstrate that increases in tilt after irrigation are positively correlated with changes in ocular torsional eye movements. When the direction of the slow phase of the torsional eye movement induced by the caloric is congruent with that induced by the rotating visual stimulus, there is a significant increase in tilt. When these two torsional components are in opposition there is a decrease. These findings show that measures of visual dependence can be influenced by oculomotor responses induced by caloric stimulation. The findings are of significance for clinical studies as they indicate that VD, which often increases in vestibular disorders, is not only modulated by changes in cognitive style but also by eye movements, in particular nystagmus.
