Abstract

We take a particular interest in things that belong to us; we remember them better and we pay them more attention when they appear in the environment. How this 'self prioritisation' comes about remains poorly understood however. The aim of this project is to use a new procedure we have developed in order to understand how 'self prioritisation' affects basic perceptual processes. In our new procedure we can 'tag' a geometric shape with self relevance and we can then study how basic perceptual processing for that shape changes when compared with other matched shapes. In the project we will conduct a series of experiments that examine whether 'self prioritisation' affects spatial and temporal attention to stimuli. The research will provide a first-ever analysis of the effects of a 'social' variable (the self) on difference stages of perception.

Data collection mode

The primary data were based on reaction times and accuracy of performance when people are asked to match a label to a shape, and the results are presented in tables organised for label (first) and then shape (second). The labels corresponded either to the self (you), your friend or a stranger, or (in different experiments) a high, medium or low reward value. The behavioural tasks required people to respond 'match' when the shape and label matched and 'mismatch' when shapes and labels were re-paired (shape with incorrect label). In addition, we ran two fMRI experiments and collected Blood Oxygen Level Dependent (BOLD) responses in the same matching and mismatching conditions. The data are presented here based on the mean reaction times, percentage correct responses and mean BOLD response for match and mismatch trials according to the label-shape pairing. The fMRI data are separated for brain regions of primary interest - the ventro-medial prefrontal cortex (a self representation region), the left posterior superior temporal sulcus (region linked to social attention) and the left intra-parietal sulcus (region linked to attentional control). For the fMRI experiments, the conditions are also listed according to the shape (e.g., ss=shape self) and label used (ls=label self).
