The role of goal-directed processes in the causation of seemingly habitual behavior KU Leuven
People sometimes do not behave in line with their explicit goals or not in their best interest. Examples of such suboptimal behaviors are action slips (e.g., entering an old password), impulsive behaviors (e.g., unhealthy eating), and behaviors in psychopathological disorders (e.g., substance use and compulsions). Suboptimal behaviors frequently occur under conditions such as stress or time pressure. The research questions addressed in this ...
Toward an increased understanding of suboptimal behavior from a goal-directed perspective KU Leuven
People often engage in suboptimal behaviors that do not align with their explicit goals. Examples are action slips, impulsive behaviors, and behavioral reluctances. These types of behavior are especially likely when a behavior has been selected frequently in the past and when individuals face poor operating conditions (e.g., a lack of time, attention, or motivation) due to fatigue, stress, or cognitive load.

Reconnecting learning and memory: the effect of retrieval manipulations effective conditioning. KU Leuven
! Any layman would agree that learning and memory are intimately connected
processes. Memories carry what has been learned; learning is only effective when it is
memorized. It is surprising that the influential domains of learning and memory have
largely evolved in separation over the last decades. With few exceptions, there have
been virtually no cross-fertilizations. In the domain of Pavlovian conditioning (a ...
The power of goal-directed processes in the causation of emotional and other actions KU Leuven
People often engage in behavior that is not in their best interest. For instance, they engage in unhealthy behaviors such as smoking, commit action slips such as taking a wrong habitual route, or they become aggressive even when they risk a high cost (e.g., retaliation or ruining a relationship). To make sense of these so-called suboptimal actions, theorists have come up with dual process models that distinguish between (a) a stimulus-driven ...

Variability in multistable apparent motion perception KU Leuven
Visual perception is not merely the result of stimuli being processed by passive observers. Our perceptual system actively disambiguates and interprets the information it receives from our eyes. Multistable perception of ambiguous stimuli allows to make a clear distinction between stimuli and perception. Perceptual multistability occurs when one stimulus leads to multiple different percepts in the same observer. This way, we can study how a ...
Colour appearance modelling of unrelated self-luminous stimuli KU Leuven
Colour appearance models, i.e. models that attempt to predict the colour appearance of a stimulus by taking the physical properties of the stimulus and its surroundings into account, have been developed and investigated for more than 40 years. Most of these models were developed to handle related colours, i.e. colours perceived in relation to other colours. A typical example is the ‘reflected’ colour of an object as seen in an illuminated ...
The role of goal-directed processes in the causation of emotional behavior studied with TMS/MEP KU Leuven
Modelling the perception of light sources KU Leuven
Colour Appearance Models (CAM) attempt to predict the colour appearance of a stimulus by taking the physical properties of the stimulus and its surroundings into account. The fundamental goal is to look for correlates between the measured optical spectral data of a stimulus and its surrounding and the corresponding perceptual attributes. There are three absolute colour attributes (Brightness, Colourfulness and Hue) and three relative colour ...
