Neural mechanisms for response selection: comparing selection of items and responses from working memory.
(Elsevier, 2007)Recent functional imaging studies of working memory (WM) have suggested a relationship between the requirement for response selection and activity in dorsolateral prefrontal (DLPFC) and parietal regions. Although a number ... -
Vigilant Attention
(MIT Press, 2004)When train drivers pass through warning or stop signals ? as they do many thousands of times per day throughout the world ? this is an example, we argue, of an inefficiency in the functioning of a right hemispheric, ... -
Comparability of functional MRI response in young and old during inhibition
(Lippincott, Williams and Wilkins, 2004)AB When using fMRI to study age-related cognitive changes, it is important to establish the integrity of the hemodynamic response because, potentially, it can be affected by age and disease. However, there have been few ... -
Individual differences in the neuroanatomy of inhibitory control
(Elsevier, 2006)We combined the data of five event-related fMRI studies of response inhibition. The re-analysis (n = 71) revealed response inhibition to be accomplished by a largely right hemisphere network of prefrontal, parietal, ... -
Avoiding another mistake: Error and posterror neural activity associated with adaptive posterror behavior change
(Psychonomic Society, 2007)The magnitude of posterior medial frontal cortex (pMFC) activity during commission of an error has been shown to relate to adaptive posterror changes in response behavior on the trial immediately following. In the present ... -
Visual sensory processing deficits in Schizophrenia and their relationship to disease state
(Springer, 2008)Context: Visual Evoked Potential (VEP) abnormalities have been a fairly consistent finding in patients with schizophrenia, and it has been suggested that electrophysiological markers of early sensory processing may be ... -
Are auditory-evoked frequency and duration mismatch negativity (MMN) deficits endophenotypic for schizophrenia? High-density electrical mapping in clinically unaffected first-degree relatives, recent-onset and chronic schizophrenia
(Elsevier, 2008)Mismatch negativity (MMN) is a negative-going event-related potential (ERP) component that occurs in response to intermittent changes in constant auditory backgrounds. A consistent finding across a large number of studies ... -
Acute effects of cocaine on the neurobiology of cognitive control
(Royal Society Publishing, 2008)Compromised ability to exert control over drug urges and drug-seeking behaviour is a characteristic of addiction. One specific cognitive control function, impulse control, has been shown to be a risk factor for the development ... -
Prefrontal and midline interactions mediating behavioural control.
(Blackwell, 2009)Top-down control processes are thought to interact with bottom-up stimulus-driven task demands to facilitate the smooth execution of behaviour. Frontal and midline brain areas in humans are believed to subserve these control ... -
Menstrual cycle phase modulates cognitive control over male but not female stimuli
(2008)Evolutionary selection pressures have been one of the factors proposed to underlie sex differences in inhibitory control. Consequently, inhibitory control may vary as a function of the menstrual cycle and may be modulated ... -
A review of neuropsychological and neuroimaging research in autistic spectrum disorders: Attention, inhibition and cognitive flexibility
(2008)Autistic spectrum disorders (ASD) are devastating neurodevelopmental disorders of unknown aetiology with characteristic deficits in social interaction, communication and behaviour. Individuals with ASD show deficits in ... -
The neural correlates of deficient error awareness in attention-deficit hyperactivity disorder (ADHD)
(2009)The ability to detect and correct errors is critical to adaptive control of behaviour and represents a discrete neuropsychological function. A number of studies have highlighted that attention-deficit/hyperactivity ... -
Quantitative analysis of ATM safety issues using retrospective accident data: The DRM project
(Elsevier, 2009)The Dinamic Risk Modelling was a research project aimed at developing a simulation approach able to provide a quantitative analysis of some critical activities of Air Traffic Control (ATC) operators considering the ... -
Self in Schizophrenia: A Discourse Analysis
(2008)Objectives: Lysaker and Lysaker (2002) employ a dialogical theory of self in their writings on self disruption in schizophrenia. It is argued here that this theory could be enriched by incorporating a discursive and ... -
Impact of speed change on estimated journey time: Failure of drivers to appreciate relevance of initial speed
(Elsevier, 2009)Higher speeds are associated with increases in the probability of crashing and the severity of the outcome. Logically drivers speed to save time, and research evidence supports this assertion. It is therefore important to ... -
Activation and deactivation during the rapid visual information processing task: an fMRI study.
(MIT Press, 2003)Sustained attention deficits occur in several neuropsychi- atric disorders. However, the underlying neurobiological mechanisms are still incompletely understood. To that end, functional MRI was used to investigate ... -
Do antisaccade deficits in schizophrenia provide evidence of a specific inhibitory function?
(Cambridge University Press, 2006)Background: Despite its inhibitory control requirements, antisaccade deficits have been consistently associated with working memory impairments in schizophrenia. We investigated whether variance in antisaccade per formance ... -

When Falsification Fails
(The Psychological Society of Ireland, 1998)This study investigated the effectiveness of a falsification logic at early and late stages of the hypothesis testing process. The subject's task was to discover the "laws of motion" in a computerized Artificial ... -
Serial attention within working memory.
(Psychonomic Society, 1998)It is proposed that people are limited to attending to just one ?object? in working memory (WM) at any one time. Consequently, many cognitive tasks, and much of everyday thought, necessitate switches between WM items. ...
