Top-down selection in ageing
Top-down attention selection may involve both target enhancement and distractor suppression. These mechanisms, however, appear to be differentially affected in ageing. In particular it has been argued that distractor suppression is impaired as we age (Gazzaley et al., 2005). In accordance with this concept we have previously shown (Tsevetanov et al., 2013) that older participants are particularly impaired at ignoring salient distracters when instructed to respond to low salient targets – Salience based selection.
In this project we will investigate the neural signature of this altered selection as we age and the factors that may alter performance in old adults. We will use brain imaging techniques (fMRI and EEG) with older participants as well as brain stimulation techniques (TMS) with younger participants.
A successful candidate will be expected to have some familiarity with these methodologies (though they will be trained during the project) and sufficient background in the attention/perception literature in general.
Self-funded students may wish to apply.
There are a number of currently open competitive studentship schemes at the University of Birmingham, and students are welcome to discuss their eligibility for these with the supervisor or the PG Admissions Tutor.
