Visual attention & perception

This research theme mainly revolves around how humans process visual scenes. It is generally agreed that visual attention plays a critical role in dealing with the 'information overload' from such scenes typically. CPL's projects focus on how attention is directed towards behaviourally-relevant objects (visual search) and how these objects are recognized (object recognition). An interesting question (and rarely examined) is how the speed of finding object is balanced with the quality of detection (speed-accuracy-trade-off). Performing this balancing act is often attributed to cognitive control.

Interaction between visual processing and movement execution

This research them is a more recent addition to CPL's research activities. It links with the visual attention&perception theme and is interested in how the processing of visual scenes is translated into reach movements towards behaviourally-relevant objects e.g., reaching for your cup of coffee on the breakfast table while ignoring the beer glass from last night. In cognitive neuroscience this constitutes a relatively novel research question as typically movement control and visual processing are examined separately. However, CPL novel approach is to examine both mechanisms in the same experimental set-up (e.g., choice reaching task). This empirical work also goes along with the development of control architectures for robot arms aiming to mimic human reaching (robotics models).

Affordances & tool use

In this theme CPL examines how humans extract action possibilities (e.g. grasping, turning, and hammering) from visual objects. This theme particularly focus on how humans realize this extraction without the usage of semantic information (i.e., without recognising objects) and instead use geometrical properties e.g., handles. In recent years, CPL has extended this theme to how we are able to use tools. Of particular interest is the question how we are able to decide that we can use a pocket knife to turn a screw i.e., unusual tool use. Hereby CPL focuses not only on affordances but also at the involvement of problem solving.

Psychological disorders

This theme is the latest addition to CPL's activities. CPL's contribution mainly focuses on using advanced statistics and computational modelling of cognitive mechanisms to advance our understanding of these disorders.

Social processes

In this research theme CPL mainly focus on how a person's traits (e.g., good, intelligent, etc.) are inferred from the person's behaviours (e.g., helped an older lady across the street).
In addition we explore how the behaviour of social groups links with the behaviour of individuals using agent-based models.
