Rebecca Lawson's researchMy research investigates how we use vision and haptics (our sense of active touch) during locomotion, object recognition and perceptual estimation. To do this I manipulate memory, context and attentional demands. My research spans a diverse range of topics within these broad areas. Some specific questions that I am interested in include: - how do our gaze strategies influence our stability whilst walking outside in everyday environments? - how do we achieve visual and haptic object constancy (ie how do we consistently categorise objects when the same object can appear so different when we re-encounter it?) - how do we categorise stimuli in order to discriminate between different shapes? - what causes our visual preferences for direct eye gaze in human faces? - what do people perceive when they look at mirrors and windows and what do people believe about how mirrors and windows work? - what misunderstandings do people have about how everyday objects function? If you want to contact me about my research, my email address is rlawson@liv.ac.uk. I am always interested in discussing options for doing a PhD with me.
I investigate how humans extract visual information from the outside world as they move around and how they recognise, categorise and understand the function of everyday objects. I am interested in how gaze alters when we walk over more challenging surfaces. I test how our visual system achieves view generalisation for similar and dissimilar objects by comparing performance with novel objects to everyday, familiar objects and for 2D images relative to 3D objects. I also investigate whether accounts of visual object recognition can be extended to predict performance at haptic object recognition and if objects presented visually or haptically activate bi-modal (visual-haptic) representations. In addition I probe what people understand about how objects function and the limitations of their knowledge. Together this research provides converging evidence about how people process different sources of information about their everyday environment and familiar objects in the world. The aim is to establish a coherent theoretical framework for understanding the perceptual and conceptual processes involved in scene and object recognition and understanding.
Forgotten why this matters? Here's one of my favourite xkcd cartoons about it. If you want to know more about aviation and climate change try wikipedia or Airportwatch. And if you care about your carbon emissions then ask to use a telepresence robot to present your work at distant conferences. I have requested this several times over the years to both psychology and computer science conferences. The answer has always been no. Why?
