Neural Executive Attentional Control in Robots
نویسندگان
چکیده
We have developed a robot controller based upon a neural implementation of Norman and Shallice's model of executive attentional control in humans. A simulation illustrates how attentional control leads to the suppression of action selection errors in neurally controlled robots. A related demonstration illustrates how lesioning of the control architecture leads to behavioural pathologies that resemble those seen in human patients with damage to the prefrontal cortex.

The role of executive control in human drug addiction.
Recent neurobiological models propose that executive control deficits play a critical role in the development and maintenance of drug addiction. In this review, we discuss recent advances in our understanding of executive control processes and their constituent neural network, and examine neuropsychological and neuroimaging evidence of executive control dysfunction in addicted drug users. We ex...
متن کاملFunctional deficits of the attentional networks in autism
Attentional dysfunction is among the most consistent observations of autism spectrum disorders (ASD). However, the neural nature of this deficit in ASD is still unclear. In this study, we aimed to identify the neurobehavioral correlates of attentional dysfunction in ASD. We used the Attention Network Test-Revised and functional magnetic resonance imaging to examine alerting, orienting, and exec...
متن کاملFos expression in the brains of rats performing an attentional set-shifting task
Impairments in executive function and cognitive control are a common feature of neuropsychiatric and neurodegenerative disorders. A promising behavioral paradigm for elucidating the neural mechanisms of executive function is extradimensional/intradimensional (ED/ID) shifting, which places demands on executive function by requiring the adjustment of behavioral responses based on affective or att...
متن کاملExecutive Attention and Action Selection in a Neurally Controlled Simulated Robot Executive Attention, Task Selection and Attention-based Learning in a Neurally Controlled Simulated Robot
We describe the design and implementation of an integrated neural architecture, modelled on human executive attention, which is used to control both automatic (reactive) and willed action selection in a simulated robot. The model, based upon Norman and Shallice’s supervisory attention system, incorporates important features of human attentional control: selection of an intended task over a more...
متن کاملAn Event-Related Potential Investigation of the Effects of Age on Alerting, Orienting, and Executive Function
The present study compared young and older adults on behavioral and neural correlates of three attentional networks (alerting, orienting, and executive control). Nineteen young and 16 older neurologically-healthy adults completed the Attention Network Test (ANT) while behavioral data (reaction time and error rates) and 64-channel event-related potentials (ERPs) were acquired. Significant age-re...
