Theatrical Latency: Walking Katrina Palmer’s The Loss Adjusters

In this article I introduce the term ‘theatrical latency’ as a pleasurable effect experienced when listening to sound in relation to visual perception. Latency refers to both the phenomena of audio delay (in feedback from analogue to digital conversion and the momentary lapses experienced when playing live with recorded music) and a theatrical sensation that comes from the reanimation of visual environments through aural framing. In this configuration, the notion of latency takes on a double meaning as both a recorded phenomenon and the retrieval of something dormant within physical objects, sites or materials. These ideas will be introduced through my experience of walking Katrina Palmer’s site-specific audio work The Loss Adjusters (2015) on the island of Portland (UK). The audio tracks create an extended meditation on Portland, interweaving specific locations and histories with fictional characters and ghosts of the island.

A Practical Approach to Using Motion Capture in Performance Dance

Markerless systems are becoming more ubiquitous due to their increased use in video games consoles. Cheap cameras and software suites are making motion capture technologies more freely available to the digitally inclined choreographer. In this workshop we will demonstrate the opportunities and limitations provided by easily accessible and relatively inexpensive markerless motion capture systems. In particular we will explore the capacity of these systems to provide useful data in a live performance scenario where the latency, size and format of the captured data is crucial in allowing real-time processing and visualisation of the captured scene

Investigating Behaviour and Face Encoding in a Hypothetical Real-World Social Contract: Handwashing in Hazardous Health Settings

Investigations into the evolutionary origins of human cognition has shown that individuals’ memory for others is influenced by the latter’s behaviour in social contracts. Such research is primarily based on hypothetical or more abstract forms of social contracts, whereas an application of this knowledge to everyday health behaviours can be of great value. To address this, the current study investigated whether participants who were asked to imagine themselves in a hypothetical hazardous health scenario showed differential response sensitivity (d’) and latency (RT) to faces of hospital staff tagged with contrasting hand hygiene before touching patients: clean hands, dirty hands, or unknown hand-washing behaviour (control). The test used a two alternative forced-choice (2AFC: “old/new”) face recognition paradigm. The findings showed that d’ to dirty and clean hands was similar, but higher than for controls. Moreover, d’ was not affected by the occupation of hospital staff (nurses vs porters). The absence of memory gains towards clean or dirty hands points to the need for new strategies to remind patients to observe (and remember) the hand hygiene of others when exposed to hazardous health environments.
