I am a cognitive psychologist, and I joined the School of Psychology as a lecturer in the early 1990s, after researching and teaching at a number of other universities.
One interesting effect that has been found by researchers in this field is that naming times are slowed when pictures from the same category are named (e.g., several pictures of animals). So one aspect of my research is directed at understanding this kind of semantic interference effect.
Another task that involves name retrieval for semantically related items is the category fluency task. Here, people are asked to generate as many items as they can for a given category e.g., animals. I am interested in evaluating novel ways of assessing performance in this type of task.
Understanding the specific processes involved in category fluency and picture naming is important, because both of these tasks are used by clinical neuropsychologists, when screening for memory or language difficulties.
