ABSTRACT
Head-mounted video cameras allow non-reactive and continuous recording of events in real time. Their use enables the capture of aspects of decision making which hitherto have only been possible to measure in the constrained environment of the laboratory. Own-point of view video recording provides a particularly powerful stimulus for evoking the recall of a wide range of cognitive and affective experiences with minimum distortion of the complexity and dynamics of these experiences. In this chapter we (a) note key methodological problems which limit the conduct of ecologically valid research into human behaviour in complex naturalistic settings, (b) introduce head-mounted video as a theoretically-grounded solution to these problems, and (c) outline the techniques which we have developed or adapted to maximise the quality and utility of data generated by use of head-mounted video cameras.
