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 ... -
The Irish mind abroad - the experiences and attitudes of the Irish diaspora

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. ... -
Multiple neuronal networks mediate sustained attention
(MIT Press, 2003)& Sustained attention def icits occur i n several neuropsychi- atric di sorders. However, the underlying neurobiol ogical mechani sms are stil l i ncompletely understood. To that end, f unctional MRI was used to ... -
Cingulate hypoactivity in cocaine users during a GO/NOGO task as revealed by event-related fMRI.
(Society for Neuroscience, 2003)Although extensive evidence exists for the reinforcing properties of drugs of abuse such as cocaine, relatively less research has addressed the functional neuroanatomical correlates of the cognitive sequelae of these ... -
Predicting success: The effect of pre-target cueing on inhibition performance.
(MIT Press, 2004)The present study investigated the relationships between attention and other preparatory processes prior to a response inhibition task and the processes involved in the inhibition itself. To achieve this, a mixed ... -
A pattern recognition approach to the detection of single-trial event-related fMRI.
(IFMBE, 2004)Functional magnetic resonance imaging (FMRI) is an imaging technique for determining which regions of the brain are activated in response to a stimulus or event. Early FMRI experiment paradigms were based upon those ... -
Executive `brake failure? following deactivation of human frontal lobe
(MIT Press, 2006)In the course of daily living, humans frequently encounter situations in which a motor activity, once initiated, becomes unnecessary or inappropriate. Under such circumstances, the ability to inhibit motor responses ...
