Help us research multisensory perception in sighted and non-sighted individuals

We're studying the role of vision for the developing brain, and how hearing and touch perception is influenced by the availability of vision during childhood.

The aim of this research is to understand how normally sighted and blind/visually impaired individuals use hearing and touch to precisely perceive their environment. By carrying out two studies, we will investigate how non-visual perception develops during childhood and adulthood, and how strongly it is influenced by the availability of vision early in life.

Take part

To be eligible, you must:

  • be an adult aged 18 to 70 years old or a child aged 7 to 14 years old
  • be normally sighted or visually impaired/blind, with otherwise typical development
  • speak English fluently
  • not have any hearing or tactile impairments

What you'll get

  • You will help to contribute towards vital research that will help developing technologies for visually impaired/blind individuals
  • Data collected* in this project will help answer questions about fundamental perceptual processes
  • You will receive £6 per hour or 2 credits for Quantitative Research Methods Research participation scheme

What's involved

We are looking at how well our brains combine hearing and touch when estimating object size. Therefore, you will be asked to attend one or two experimental sessions.


In the first session, you will play an object size discrimination game whereby you will be blindfolded and will only be able to touch or hear the objects in order to estimate their size.

The second session will use a similar object size perception task, but this time we will record your brain activity with an electroencephalogram (EEG). EEGs are non-invasive, don’t hurt and involve wearing an EEG cap. They externally record signals coming from the brain and will tell us how this helps you perceive the world.

The sessions will take about 60 minutes each and they can be conducted either on the same or on separate days. The research will be held in a laboratory at the University of Bath or in the Wolfson Centre at University College London.
