Impairment of probabilistic reward-based learning in schizophrenia.
30 Aug 2009 
Recent models assume that some symptoms of schizophrenia originate from defective reward processing mechanisms. Understanding the precise nature of reward-based learning impairments might thus make an important contribution to the understanding of ...

Visual adaptation to goal-directed hand actions.
30 Aug 2009 Prolonged exposure to visual stimuli, or adaptation, often results in an adaptation "aftereffect" which can profoundly distort our perception of subsequent visual stimuli. This technique has been commonly used to investigate mechanisms underlying ...

Event-related brain potentials suggest a late interaction of meter and syntax in the P600.
30 Aug 2009 Many studies refer to the relevance of metric cues in speech segmentation during language acquisition and adult language processing. However, the on-line use (i.e., time-locking the unfolding of a sentence to EEG) of metric stress patterns that are ...

A multisensory cortical network for understanding speech in noise.
30 Aug 2009 In noisy environments, listeners tend to hear a speaker's voice yet struggle to understand what is said. The most effective way to improve intelligibility in such conditions is to watch the speaker's mouth movements. Here we identify the neural ...

30 Aug 2009 Past experience is hypothesized to reduce computational demands in PFC by providing bottom-up predictive information that informs subsequent stimulus-action mapping. The present fMRI study measured cortical activity reductions ("neural ...

Learning to become an expert: reinforcement learning and the acquisition of perceptual expertise.
30 Aug 2009 To elucidate the neural mechanisms underlying the development of perceptual expertise, we recorded ERPs while participants performed a categorization task. We found that as participants learned to discriminate computer generated "blob" stimuli, ...

Mind your left: spatial bias in subcortical fear processing.
30 Aug 2009 Hemispheric lateralization of emotional processing has long been suggested, but its underlying neural mechanisms have not yet been defined. In this functional magnetic resonance imaging study, facial expressions were presented to 10 right-handed ...

30 Aug 2009 Although significant insights into the neural basis of numerical and mathematical processing have been made, the neural processes that enable abstract symbols to become numerical remain largely unexplored in humans. In the present study, adult ...

30 Aug 2009 Metamemory refers to knowledge and monitoring of one's own memory. Metamemory monitoring can be done prospectively with respect to subsequent memory retrieval or retrospectively with respect to previous memory retrieval. In this study, we used fMRI ...

Cross-modal emotional attention: emotional voices modulate early stages of visual processing.
30 Aug 2009 Emotional attention, the boosting of the processing of emotionally relevant stimuli, has, up to now, mainly been investigated within a sensory modality, for instance, by using emotional pictures to modulate visual attention. In real-life ...
