Dr Andrew Kolarik

Description: Andrew Kolarik

Andrew gained a BA in Psychology at Cardiff University in 2003. His PhD, ‘Binaural Resolution,’ was awarded in 2006 and involved measuring and modelling binaural temporal window durations and auditory filter widths.

Andrew’s first postdoctoral position investigated research in the field of vision science, also at Cardiff University. The post assessed accuracy and precision of eye movements in the ageing population. He then worked as a Research Fellow at the Vision and Eye Research Unit (VERU) at Anglia Ruskin University. The project involved investigating how blind and low vision listeners made use of two acoustic distance cues (level and reverberation) to improve their spatial awareness, and how use of acoustic cues was enhanced among blind listeners.

Andrew then spent time as a Research Associate at the University of Cambridge in Professor Brian Moore’s research group before returning to Anglia Ruskin University and then to the University of London, working in a group headed by Professor Colin Blakemore. His work looks at auditory perception among hearing impaired and blind listeners. He is interested in how sensory impairment affects spatial awareness, and to what extent supra-normal performance for auditory spatial tasks among blind listeners, such as distance discrimination and azimuthal localization, can be explained by cross-modal cortical reorganization. His work uses virtualization techniques and self-report to investigate whether accurate internal representations of auditory space are formed in the absence of a visual signal, and under what conditions blind individuals demonstrate supra-normal hearing abilities. His work looks at spatial awareness and speech perception among hearing impaired and blind listeners.

Andrew is a member of the British Society of Audiology and Cambridge Neuroscience. He is an Honorary Visiting Research Fellow at Anglia Ruskin University
