PREFRONTAL CORTEX ACTIVITY DURING ATTENTIONAL BIAS CONDITIONING WITH FEARFUL FACES: A NEAR-INFRARED SPECTROSCOPY ANALYSIS
… a fearful facial expression elicits an automatic orienting of attention. Past research focusing on fear conditioning has used an unconditioned stimulus that the participant directly experiences (e.g. shock). Other research has focused on observational fear learning where the participant watches …

EEG and fMRI studies of the effects of stimulus properties on the control of attention
In this dissertation the effects of variations in stimulus properties and CTOA, in auditory attention tasks were explored using recently developed approaches to EEG analysis including LIMO. The last experiment was structured using information theory, designing an effective experiment. Four studies …

The Use of Social Gaze Cues in Real World Scenes
Eyes are an ideal tool for investigating social attention, as their physiological composition with the iris and pupil highly-distinguishable against the white sclera, combined with our foveated vision, mean that gaze cues are both a means of understanding where attention is being allocated and a …

In the visual system, an influence of attention on sensory processing was repeatedly demonstrated on …
